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.
