Can Any LED Light Fixture Be Used As A LED Tunnel Light?

 


 

Tunnel lights are special lamps used for tunnel lighting to solve the “black hole effect” or “white hole effect” caused by sudden changes in brightness when vehicles enter or exit the tunnel. Tunnels are special sections of high-grade highways, and a series of visual problems will appear when vehicles drive into, pass through and leave the tunnel. In order to adapt to visual changes, additional electro-optical lighting needs to be set up.

 

The shell of the lamp needs to be made of alloy environmental protection material with high strength and good toughness, and the transparent part is reinforced tempered glass, which is dustproof, waterproof, corrosion-resistant, and rust-proof. It has strong anti-collision and impact ability; multi-channel anti-shock structure and high-tech surface spraying treatment, all kinds of close-range high-strength and high-frequency vibrations cannot affect the lamps and can be used in workshops, roadbeds, rails, etc. High-frequency vibration and humidity, Long-term stable work in a high-temperature environment. Good electromagnetic compatibility, will not cause interference to the transmission network.

 

Generally, tunnel lights use energy-saving light sources, which have high luminous efficiency and long service life. With different reflectors, they can realize multi-purpose lighting; and after softening treatment, they will not cause glare or other uncomfortable reactions. The ballast adopts overheating protection technology to ensure the service life of the lamp. Imported high-purity mirror aluminum anodized material is used as the reflector and is designed through precise light distribution. The power factor is greater than 0.9, the reflective efficiency is high, the light transmission is good, and energy saving and environmental protection.

LED Tunnel Lights Have Experienced 5 Update Iterations From Birth To Now

 


 

 

  • Integrated LED Light Source Tunnel Light

The earliest LED tunnel lights are traditional high-pressure sodium lamp tunnel lights shell modified LED light sources, basically integrated LED light source tunnel lights, old style, no new ideas, and no special radiator device, LED light source heat dissipation is not good, light decay Big, short life. The emergence of this LED tunnel light is of great significance, breaking the dominance of high-pressure sodium lamps in tunnel lights, and giving tunnel lighting more choices. This hybrid product has been used for about two or three years and then withdrawn from the market.

 

 

  • Special LED Lamp Body With Heat Sink

The second-generation LED tunnel light products have a special LED lamp body and a heat sink, but the light source is still an integrated LED light source, the heat is relatively concentrated, and there is also a heat dissipation problem, and the service life is not very long. However, there are some improvements compared to the first-generation products. First, there is a cooling device, and second, it is equipped with a lens, and the light distribution is more reasonable. The disadvantage is that the heat dissipation is not ideal, the lamp body is thick and easy to deform, more aluminum materials are used, and the cost is higher.

 

 

  • Flat LED Tunnel Light

The third-generation LED tunnel light product is a flat LED tunnel light, and the light body is made of an aluminum profile and tempered glass surface. This LED tunnel light is more classic and has been popular for the longest time, lasting for six or seven years. It can be said that it is a generation of LED tunnel light products that are not fading. The advantage of this product is that the LED light source is changed to a single 1W high-power LED lamp bead, the aluminum profile lamp body with an integrated radiator structure, heat dissipation, and good heat dissipation effect, and the single high-power packaged LED light source has high light efficiency. long life. The disadvantage is that more aluminum is used, the light transmittance of the tempered glass surface is not very high, and the glass is fragile. The light distribution is to use a reflector, without a special lens, the light distribution is not very reasonable.

 

 

  • Fin Module LED Tunnel Light

 

Fin Module LED Tunnel Light

 

The fourth generation LED tunnel light is a fin module LED tunnel light. The advantage of this kind of LED tunnel light is that it uses less aluminum material, and has a large heat dissipation area and good heat dissipation effect. The light-transmitting surface is changed to a PC cover with an integrated lens, which has high light transmittance, good toughness, and is not easy to break. The light source is changed to SMD LED light source to further reduce the cost. The disadvantage is that the surface of the lamp body is not smooth enough, there are many dead spots, it is easy to collect dust, and it is difficult to clean.

 

 

  • Die-Cast Aluminum Module LED Tunnel Light

The fifth-generation LED tunnel light is a die-cast aluminum module LED tunnel light. The appearance of this generation of LED tunnel light is similar to that of the fourth-generation fin module, but the material of the lamp body is changed to die-cast aluminum, and the surface of the lamp body is smoother and easy to clean. The production cost of the whole lamp is further reduced, and it is a more popular style of LED tunnel lamp at present. The fifth-generation LED tunnel light integrates the advantages of previous generations of LED tunnel lights and has the lowest cost, so it is widely used. At present, most of the tunnel lights on the market are this kind of die-casting module LED tunnel lights.

 

 

What Should Be Paid Attention To When Installing Tunnel Lights?

 


 

Unlike most indoor and outdoor lighting, other lighting is not turned on until the sun goes down, or supplementary lighting is provided when the light is insufficient. As for tunnel lighting, the brighter the sunlight outside the tunnel, the brighter the lighting at the entrance and transition sections. The darker the outside light, the darker the inside of the tunnel. At night, the lowest level of lighting is treated as ordinary roads.

 

We have actually measured the illuminance outside the entrance of many tunnels. The illuminance of the road surface at noon in summer exceeds 100,000 lx, and the illuminance of the road surface at the end of the entrance section of many tunnels is less than 1 lx during the day without lights. With such a large contrast, no one’s eyes can suddenly transition from photopic vision to scotopic vision within 2 seconds.

 

Tunnel lighting designers should carefully understand the standards and site conditions, and then carefully give the brightness Lth of the entrance section. The key point should be clear: before the design, it is very important to measure the brightness L20(S) outside the tunnel, which is the most critical link related to the success or failure of the entire tunnel lighting design.
