https://www.ledmeen.com/products/lw-23w-4-linear-wall-mounting-lighting/

The color of ceilings, wall decorations, floors and even furniture will affect the performance of lights, so it must not be neglected when choosing lighting. If the main color of the home environment (mainly the color of the wall) is a high-brightness light color, such as white, beige, bright yellow, extremely light gray, etc., you can choose relatively low-brightness soft lighting to avoid glare; if it is low Walls with bright colors, such as dark blue, burgundy and other deep colors, need to cooperate with lamps with higher brightness.

The overall furniture style and arrangement determine the style and orientation of the wall-mounted linear LED lighting. The safe way is to match the modern with the modern and the classical with the classical. Of course, there are also masters who can achieve good results by mixing the modern and the classical, but they must be carefully Considering, there must be an echo between the classical and the modern. If it is piled up randomly, it will lose the quality. The size, height and orientation of sofas, coffee tables, dining tables, desks, beds, bedside tables and other furniture are the main basis for the size, height and orientation of the table lamps, chandeliers, and floor lamps that cooperate with them. The distribution of lamps and lanterns should not be too concentrated. Chandeliers, wall lamps, table lamps, floor lamps, etc. have different lighting effects. The light is strong or weak. Concentrated settings will cause light disorder, unclear intentions, and damage to the atmosphere of the room. In addition, it should be noted that the orientation of the lamps should be uneven and orderly, and should not be too concentrated at a certain level to avoid dazzling and messy.

1. Home LED tube lighting collocation method

(1) Saving electricity is a necessary factor to consider

There is no better way to save electricity than to use natural light, so your lighting setup should work with it too. First understand the orientation of the furniture, the orientation and size of the windows. Daytime light conditions. If the lighting with adjustable brightness and darkness is used, it can coordinate the needs of nighttime lighting and make up for the lack of natural light sources during the day.

(2) The layout of the power supply in the room is also very important

Without sufficient power supply, no matter how beautiful the lighting is, it is useless. Wall-mounted linear LED lighting fixtures should be properly coordinated with other indoor electrical appliances to avoid potential safety hazards due to circuit overload. In short, all indoor lighting should be considered as a whole, planned in advance, and then purchased and installed, and should not be arbitrary and half-hearted.

2.How to choose LED tube lighting

LED tube lighting in the bedroom is very important for people's daily life. Because it not only plays the role of lighting, but also the decorative effect is very important. So how to match LED home lighting? Many people don't know how to choose lamps after decorating their houses.

(1) Consider the bedroom decoration style

Generally speaking, when it comes to home decoration, there will be a unified style. The overall style will be considered when other individual decorations are made. If the bedroom is a modern and minimalist style, then the choice of lighting should choose modern led bedroom lights. If the bedroom is a classical style, then you should choose European-style crystal lamps, but it should be noted that no matter which style it is, it must pay attention to coordination and unity. Otherwise, it will make people feel awkward, and the effect is not good.

(2) Consider the population living in the bedroom

Because the people living in the bedroom are different, the LED tube lighting at home is also different. If it is a room where children live, some lamps with soft lighting should be selected, otherwise the strong light will stimulate the children's sight and affect the children's health. If you are an elderly person, you should also choose some soft and strong lighting. Because the elderly are generally inconvenient to move at night, if the lights are dim, it will affect the movement. And if two people live, you can choose a wall lamp facing the head, or a spotlight. This can increase the romantic effect. It can also play a role in setting off the family atmosphere.

LED light strips are widely used in home decoration, but where should the light strips be installed in the home? Many people are a little unclear. In fact, the use of light strips can greatly increase the three-dimensional layering of the house and also assist the lighting of the house.

1. Application of recessed linear LED strip light in bedroom

The lighting design is like putting on makeup for the interior, it not only makes the space look elegant and light, but also highlights the level of the space. The recessed linear LED strip light design in warm colors will make the bedroom more warm. The LED light strip installed on the bedside of the bedroom can not only beautify the bedroom but also act as a night light.

2. Application of recessed linear LED strip light in living room

The LED light strips surround along the ceiling curve, and the translucent light is refracted to deploy the open space, which will make the whole living room brighter. Installing LED light strips in the grooves of the TV background wall can enhance the three-dimensional sense of space, and even simple lines can show a different dynamic beauty.

3. Application of recessed linear LED strip light in bathroom

It is a very trendy way to install LED light strips around the wall of the bathroom. It is simple and beautiful, and it is easier to highlight the personality and style. The LED light strip around the bathroom mirror can create an atmosphere, and secondly, it provides the basic lighting needs. If the LED light strip is hidden on the top or around the bathroom mirror, the light is projected without worrying about backlight and polarized light.

4. Application of recessed linear LED strip light in kitchen

Although headlights are also installed at the top of the kitchen, it is very inconvenient for cooking at night to be blocked by shadows. It is very inconvenient to install recessed linear LED strip lights under the wall cabinet as cabinet lights, which can save these troubles and add cooking. of warmth.

5. Application of recessed linear LED strip lights in cabinets and laminates

The LED light strip device adds a light source inside the cabinet, and the wonderful combination with the shelf can weaken the closed feeling of the space and fully set off the exquisite and fashionable indoor atmosphere.

COMFORT REQUIREMENTS AND APPLICATIONS OF LED LINEAR TRACK LIGHTING FIXTURES(2023年01月14日)

ledmeen — 2023-01-12T12:35:39+0900

https://www.ledmeen.com/products/lw-46r-led-linear-recessed-lighting-with-trim.html

With the rapid development of national road traffic construction, the construction scale and number of highway tunnels are also increasing, and tunnel lighting also has problems such as energy saving and safety that need to be solved. With the maturity of LED light source technology, lighting The industry has also carried out research and application practice of LED application in highway tunnel lighting. Therefore, linear track lighting fixtures combined with advanced control methods in tunnel lighting, using a new generation of light sources with high light efficiency, good stability and long life will become a new generation of light sources. A need and trend.

1. Brightness of linear track lighting fixtures

Since the brightness outside the tunnel during the day is much higher than that inside the tunnel, when the driver drives into the tunnel, the vision needs to have a certain adaptation time before he can see the inside of the tunnel. This phenomenon is called "adaptation lag phenomenon" "If there is no proper transition, a black hole phenomenon will occur, causing the driver to temporarily lose normal visual function, which will bring certain safety hazards. The black hole phenomenon is a visual problem that occurs before entering a tunnel, and it is also the most important problem in tunnel lighting. To this end, tunnel lighting is usually divided into entrance lighting, interior lighting and exit lighting. The brightness of the tunnel entrance lighting during the day should be determined according to the brightness outside the tunnel, the speed of the vehicle, the field of view at the entrance and the length of the tunnel. The threshold segment is to eliminate the "black hole" phenomenon, and the lighting level in the transition segment is further gradually decreased, thereby providing the driver with time for visual dark adaptation.

2. Uniformity of linear track lighting fixtures

Good visual function not only requires a good average brightness, but also requires that the average brightness on the road surface and the minimum brightness should not be too different. If the brightness difference in the field of view is too large, the bright part will form a glare source, and the change of brightness and darkness will bring a certain stroboscopic effect, which will then affect the vision. Fatigue can also increase.

3. The glare of linear track lighting fixtures

The formation of glare is due to the existence of extremely high brightness or brightness contrast in the field of view, which reduces visual function or makes the eyes feel uncomfortable. Glare in tunnel lighting can come from oncoming vehicle headlights, tunnel lighting fixtures, high brightness outside at tunnel exits, and the like. Glare will reduce people's ability to recognize obstacles and endanger driving safety. Linear tunnel lighting fixtures should be cut-off type, and special technical measures to eliminate direct and reflected glare should be adopted to form diffuse reflection, so that the light can enter the human eye very softly.

The International Commission on Illumination has used relative threshold increments (TI) to account for the decline in visual function due to glare, a measure of disabling glare. The European Commission for Standardization's tunnel lighting standard specifies the following requirements for incapacitating glare: the relative threshold increment (TI) must be less than 15% in the tunnel threshold segment and inner segment during the day and the entire tunnel at night.

4. Control of linear track lighting fixtures

The advanced lighting control method is an important technique for reasonable energy saving while ensuring the visual conditions and meeting the tunnel lighting requirements. The purpose of the LED linear tunnel lighting control is that the lighting level of the tunnel can be changed at any time. Due to cloudy, rainy or twilight, the brightness outside the tunnel entrance is much lower than usual, so appropriate measures should be taken to reduce the level of lighting at the entrance to reduce unnecessary energy waste. In tunnel lighting, the illuminance of the tunnel lighting environment or the opening and closing of lights can be adjusted and controlled through various dimming devices or control devices according to factors such as day, night, and traffic flow. At present, most of the foreign countries use photosensitive devices, dimmable electronic rectifiers, etc. to form an intelligent lighting system, which reduces the overall brightness of the lamps in the tunnel and reduces the energy consumption; at the same time, the uniformity of the tunnel brightness is kept unchanged.

Serenity and comfort are the main trends in contemporary bedroom lighting. There are various schemes adopted. You can choose a ceiling lamp with a simple shape, the milky white light it emits, which contrasts with the light-colored walls of the bedroom, and it is pure; you can use light eaves lighting, so that the light is reflected through the ceiling or wall, which is very soft and pleasant; you can also install embedded ceiling lights, With the wall lamp, the "starry" direct light and the "hazy" auxiliary light complement each other, making it more elegant and warm.

The luxurious style shows the owner's financial resources and identity. The LED linear ceiling light adopts good materials and lighting to match the luxurious interior decoration. For example, with golden candle lighting and Baroque furniture, it can show the atmosphere of the French court, which is resplendent and splendid. If the mahogany lamps with meticulous workmanship, exquisite materials and exquisite shapes are used, together with simple mahogany furniture, it will be extraordinary, showing the strong national sentiment and economic strength of the owner.

1. Pay attention to the heat dissipation characteristics of LED linear ceiling lights

The shell made of aluminum alloy profiles will have an excellent heat exhaust system, which can increase the service life of the LED lamp and the actual effect of lighting. Next, the internal material is the key to all living room ceiling lamps; it can be distinguished according to the quality of the internal solar cells, the coloring of the LED lamp beads, the CRI and whether the embedded electronic rectifier is a constant current power supply and other index values. Generally speaking, the better the heat dissipation of solar cells, the better the safety, and the higher the coloring of LED lamp beads and their CRI, the better.

When installing fixtures of LED linear ceiling lights, do not install it on flammable objects. Many people will install home furniture living room ceiling lamps on three-layer wood-based panels with painted materials to make the actual effect of decorative design more beautiful and generous. This is very risky. If you're going to install on this type of material, you should also use insulation, otherwise it's very easy to ignite.

2. The LED linear ceiling light should be in harmony with the overall design style of the house

And a variety of lighting fixtures in the same room should maintain harmony in color or style. Such as wooden walls, solid wood cabinets, and square living balconies with wooden tops are suitable for square wooden lamps; square living rooms equipped with wrought iron accessories, galvanized pipe laminated glass dining table and dining chairs are suitable for ceiling lamps with square galvanized pipe materials; Bedrooms with golden cabinet door handles and golden track spotlights are suitable for lamps with golden decorative designs.

Although the way to install home LED linear ceiling lights is relatively simple, safety accidents can only be prevented by being firmly fixed. If there are children in the house, you must remind them not to throw small toys such as balloons. For lighting fixtures, doing so is very risky.

HOW TO CHOOSE THE RIGHT LED LINEAR CEILING LIGHT ACCORDING TO THE ROOM AREA?(2023年01月12日)

ledmeen — 2023-01-12T12:34:37+0900

https://www.ledmeen.com/products/lw-36m-led-linear-surface-mounting-lighting/

1. The choice of LED linear ceiling light in the living room

The living room lamp plays the finishing touch in the decoration of the whole room. Too complicated shapes and too complicated colors are not suitable for the decoration of the room with simple design, which will increase the feeling of crowding. It is also not suitable to install chandeliers in rooms with a floor height of less than 2.8 meters. Only LED linear ceiling lights can be installed to make the room appear taller and make people feel more lively and generous. In addition, the living room, as the place where the host receives guests, needs to be bright and bright in order to make people feel happy.

2. The choice of bedroom LED linear ceiling light

Apart from work, the bedroom is the place where we spend the longest time, and it is also the harbor where we relieve stress and rest our souls. Therefore, a bedroom lamp that integrates warmth, romance and freshness is particularly important. For a bedroom of 15-20 square meters, you need to choose a 24W LED linear ceiling light, and the diameter of the lamp body is between 40-50cm; for a bedroom of 12-15 square meters, you can choose a 20W LED linear ceiling light, and the diameter of the lamp body can also be It is between 40-50cm; for small bedrooms under 12 square meters, 15W linear LED ceiling lights are fine, and the diameter can be between 35-40cm. As for whether to use white light or warm light, this mainly depends on personal preference. Some friends like bright, or often study and work in the bedroom, then choosing white light will reduce eye fatigue and protect eyesight; while other friends prefer to decorate the bedroom warm and romantic, then the warm light LED linear ceiling light is the first choice. But in general, the style of modern home improvement needs to be concise and bright.

3. The choice of restaurant LED linear ceiling light

The restaurant is generally close to the kitchen, and there is heat from the food, and the fumes are relatively large. In order to keep it clean, the restaurant lights need to be cleaned frequently. Therefore, it is advisable to choose a LED linear ceiling light with a smooth lampshade. Most of my friends should have had the experience of changing light bulbs; step on the table, step on the chair, hold your head 90 degrees, and raise your arms to the roof. Compared with incandescent lamps and energy-saving lamps, LED linear ceiling lights have a long life, which saves friends from the trouble of frequently replacing light bulbs, but the convenience of removing and washing the lampshade still needs to be considered. In addition, the light of the restaurant light should make the food look full of color and fragrance, so as to increase appetite, so it is more appropriate to choose a 15-20W LED ceiling light.

In short, the area of LED linear ceiling lights should not be greater than 2%-3% of the room area. If the lighting is insufficient, the number of lamps or auxiliary light sources can be increased, otherwise the decorative effect of the room will be affected. The perfect home lighting configuration is an organic combination of practicability, artistry and rationality. Clever use of lighting lighting can not only enable you to obtain functional requirements, but also under the delicate combination of beautiful shapes, colors, patterns and light colors of lighting. The pleasant environment and atmosphere can give people a beautiful enjoyment.

https://www.ledmeen.com/products/lw-60p-ud-led-linear-up-and-down-lighting

At present, in the light source used in tunnel lighting application, the high pressure sodium lamp has been applied on a large scale because of its high visual light effect (up to 120lm/w), but there are still some difficult problems in tunnel lighting, mainly poor color rendering and limited range of light source power selection (usually only 250W and

400W), especially in the internal segment lighting, high-pressure sodium lamps on the one hand there is no smaller power, on the other hand, point-like strong light source caused by glare and strobe is more serious. In some long tunnels, straight tubular fluorescent lamps have also been used for their high color rendering and linear illumination with good visual inducement, but because of the short life span of fluorescent lamps, usually only about 8,000 hours, so often need to be replaced, greatly increasing the maintenance cost of the tunnel. In addition, fluorescent lamps have less power and do not meet the requirements in areas requiring high illumination, such as inlet segments, transition sections, and exit segments. In recent years, with the maturity of the cathode lamp technology, due to the elimination of the influence of electrode factors, infinity fluorescent lamps than traditional fluorescent lamps have a longer life, but also to achieve greater power, which makes the infinity lamp in the tunnel lighting situation reflects the advantages. However, the luminous surface of the cathode lamp is large, and the optical efficiency of the whole luminaire is low when the optical design is carried out.

Spark LED tunnel lamp can be said to be integrated with high-pressure sodium lamps, straight tube fluorescent lamps and cathode lamps of various advantages, is currently the most ideal light source in tunnel lighting applications, its advantages are mainly reflected in the following aspects:

1) High light efficiency, the current mass production single chip 1W LED light efficiency can reach more than 100lm/w, and because it is a single-sided light, in the entire luminaire optical system design process, can achieve a high luminaire efficiency.

2) long life, led in a reasonable heat dissipation design and power drive conditions, can have a life of up to 50,000 to 70,000 hours, for 24 hours of light tunnel lighting applications, can greatly reduce maintenance costs, and can shorten the return on investment period.

3) easy to match light; LED light source because the luminous size is very small, single-sided light, light directivity is very strong, so it can be very convenient with the lens or reflective cup, to achieve a more ideal light distribution, not only improve the efficiency of the entire luminaire, but also to ensure good uniformity.

4) Flexible luminaire design; Spark led tunnel lamp not only in the power design flexible, the use of 1W or so led devices, according to the actual illumination requirements to change the number of led tube lighting source, to achieve the best energy-saving effect, and because the size is very small, luminaire shape design is also very flexible,

Can be made into a linear luminaire to achieve better visual conductivity, can also be designed into rectangular lamps suitable for high illumination requirements of the inlet, transition and outlet segments.

5) Intelligent dimming control, the use of LEDs can achieve the lamp's infinite dimming, can be combined with the brightness of the hole to dynamically change the brightness of the tunnel lighting, give full play to the technical characteristics of LED tunnel lighting fixtures, and further improve the energy-saving effect of LED tunnel lamps, to achieve intelligent tunnel lighting. Spark patented intelligent LED tunnel lamp can achieve computer dimming, temperature control, automatic inspection, elevation/horizontal angle adjustable and other functions.

Lighting light efficiency 80lm/w, energy saving rate 70% Although there are still many difficulties and challenges in the large-scale application of LED tunnel lamps, such as the imperfect standard of LED lighting products, the negative impact of some inferior products on market promotion, LED tunnel lights for the first purchase cost is higher. These put pressure on the large-scale market applications of LED tunnel lighting products, but these pressures are inevitable for any new technology and new products to be encountered in the early stages of popularization and application. However, with the further development of high-power white LED technology, led tunnel lighting thermoelectric overall system technology continues to mature, people's energy saving and environmental awareness of further enhancement, LED technology will be in the field of tunnel lighting applications to create a new future of semiconductor lighting industry.

Usually the human eye can perceive a flicker of light with a frequency of up to a Hz, which is not perceived above this frequency. Therefore, in LED lighting applications, if the pulse signal appears less frequently than the low frequency component of the Hz, the human eye will feel the flicker. Of course, in specific applications, there are a number of factors that can cause LED lights to blink. For example, in offline low-power LED lighting applications, a common power topology is an isolated flyback topology. In the case of the greenpoint® reference design for 8W off-line led drivers that meet the "Energy Star" solid-state lighting standards, the dynamic self-powered (DSS) circuit may activate and trigger light flicker because the sinusoidal square wave power conversion of the Flyback regulator does not provide a constant energy for the primary bias.

In order to avoid this problem, it is necessary to make the primary bias partial discharge in each half cycle, and accordingly, the measure of the capacitance and resistance that make up the bias circuit needs to be properly selected. In addition, electromagnetic interference (EMI) filters are required even in LED drive applications that provide excellent power factor correction and support triac dimming. The transient current caused by the Triac step (step) stimulates the natural resonance of inductors and capacitors in the EMI filter. If this resonant characteristic causes the input current to drop below the Triac maintenance current, the TRIAC will be turned off. After a short delay, the triac usually leads again, stimulating the same resonance. During a half-period of the input power waveform, this series of events may be repeated multiple times, resulting in visible led flickering. In order to deal with this problem, a key requirement of triac dimming is that the input capacitance of the EMI filter is extremely low, and the capacitance can be decoupled by triac and winding impedance. According to the formula, if the capacitance decreases in the dimming module, it can increase the resistance of the resonant circuit, suppress the oscillation on the principle, and restore the desired circuit work.

1. Current voltage instability, power supply voltage rise is particularly easy to cause the destruction of LED lights, the cause of sudden increase in voltage, power supply quality problems, or improper use of users and other reasons may let the power supply voltage suddenly increased.

2. The power supply path of the led circular lighting is partially short-circuited, which is usually caused by a part of the line, or the short circuit of other wires to increase the voltage in this place.

3. It may also be that the LED is damaged due to its own quality reasons and thus forms a short circuit, and its original voltage drop is passed on to other LEDs. 4. The heat dissipation effect of the luminaire is not good, we all know that the lamp luminescence is a heat dissipation process, if the temperature inside the luminaire is too high easy to make the characteristics of the LED become bad.

This is also easy to cause damage to LED lights.

4. It is also possible that the luminaire is inside the water, because it is conductive, so it will make the lamp line short circuit. 6. Assembly time did not do a good job of anti-static work, so that the inside of the LED has been hurt by static electricity.

Although the normal voltage and current values are applied, it is also extremely easy to cause damage to the LED.

The so-called LED lamps, as the name implies, refers to the Luminaire products using LED (light-emitting diode, light-emitting diode) technology as the main source of light. LED is a solid-state semiconductor assembly, which uses the current to flow to the semiconductor p-n junction coupling, and then by the semiconductor separated by the negative electrons and the positively charged electric hole two kinds of carrier combined, resulting in photon emission, different kinds of LEDs can emit from infrared to blue, Light of different wavelengths, such as between purple light and UV rays. In recent years, the new development is to put fluorescent powder on the Blu-ray led, the Blu-ray led into White LED products.

This operation typically requires a combination of a drive circuit (LED Driver) or a power supply, the main function of the drive circuit or power supply is to convert the AC voltage to a DC power supply and simultaneously complete the voltage and current consistent with the LED to drive the matching components. LED Lamps Light bulbs small size, light weight, and epoxy resin package, can withstand high-strength mechanical impact and vibration, not easy to break, and brightness attenuation cycle is long, so its service life can be up to 50,000-100,000 hours, far more than the traditional tungsten light bubble 1,000 hours and fluorescent lamp 10,000 Hours. Because the service life of LED lamps can reach 5 ~10 years, so not only can greatly reduce the cost of luminaire replacement, but also because of its very small current can drive the characteristics of luminescence, in the same lighting effect, power consumption is only one-second of fluorescent lamps, so LEDs also have the advantages of power saving and energy savings. However, because some of the LED technology is not enough, so the initial use of the lamp on the shortcomings include light quality (color performance, consistency, color temperature) poor, heat dissipation is not easy, and the price is high, and the improper heat dissipation, will lead to the brightness of LED lamps and circuit 0 components of the service life accelerated attenuation. Manufacturing technology is surging, these shortcomings, including LED thermal resistance gradually reduced, light quality is also in the promotion. In 2008, in addition to the LED Baileng luminous efficiency has reached lm/w, and led warm white light luminous efficiency, is expected in 2010, can also be increased from the lm/w to lm/w. Compared with other general light sources, tungsten light bubble about lm/w, fluorescent fluorescent lamp about 45~60 lm/w, HID lamp about 120~150 lm/w,led luminous efficiency has obviously gradually become advantageous
