Case Location: Santo domingo, D.R;.

At the beginning of 2022, our customer installed 150w K-COB LED TUNNEL LIGHTS for a tunnel with a total length of 2KM in the Dominican Republic, with a total number of 565 lights. Today, the customer is very happy to give us feedback from the actual situation from the Dominican country. Feedback, the whole tunnel is brightly lit, which makes people feel very safe! The following are real videos and pictures taken by netizens from this tunnel.


You may be curious, the lamp used in this tunnel is a 150W tunnel lamp from K-COB. The whole lamp adopts fluorescent ceramic light source developed by K-cob patented technology and self-developed dual-channel heat dissipation technology. The lamp body is made of private die-casting aluminum, with compact structure and stylish appearance. The power supply adopts the world's top brand Infinet to ensure the safety of the power supply of the lamp body. High boron glass lens is used to achieve scientific light distribution, the light efficiency is as high as 110lm/w, and the color temperature is 6000K, which perfectly restores the traffic flow inside the tunnel and ensures driving safety.

What's is tunnel lighting?

As the name implies, tunnel lights are used in tunnels, which can be anti-corrosion, dust-proof, moisture-proof and explosion-proof. They have high requirements for tunnel lighting. There are many types of tunnel lights: LED tunnel lights, sodium lamp tunnel lights, electrodeless tunnel lights, and fluorescent tunnel lights. If the material is distinguished, there are aluminum die-casting tunnel lights, aluminum profile tunnel lights, and the layout of the tunnel lights in the tunnel also plays a crucial role. The black hole effect of the entrance section will cause glare to the driver, which will affect the driving field of vision. Therefore, the lighting value of the entrance section is very important. At present, tunnel lights are everywhere, and humans can no longer live without tunnel lights. After all, as long as there are mountains, there are tunnel lights.

What are the advantages of LED tunnel lights?

1. Safety, environmental protection, no pollution
Traditional tunnel lamps contain a large amount of mercury vapor, which will evaporate into the atmosphere if broken. However, LED fluorescent tunnel lights do not use mercury at all, and LED tunnel lights do not contain lead, which protects the environment. The working voltage of LED tunnel lights is low, mostly 1.4-3V; the working current of ordinary LEDs is only 10mA, and the ultra-high brightness is only 1A. LED tunnel lights do not add "mercury" in the production process, do not need to be inflated, do not need glass shells, have good impact resistance, good shock resistance, not easy to break, easy to transport, very environmentally friendly, and known as "green energy".
2. Efficient conversion to reduce heat generation
Traditional lamps and tunnel lamps will generate a lot of heat energy, while LED tunnel lamps convert all electrical energy into light energy without wasting energy.
3. Quiet and comfortable, no noise
LED tunnel lights do not produce noise, and are the best choice for occasions where precision electronic instruments are used. Suitable for libraries, offices, research rooms and other occasions.
4, the light is soft, protect the eyes
Traditional tunnel lamps use alternating current, so there will be 100-120 strobes per second. LED tunnel lighting directly converts alternating current into direct current without flickering and protects eyes.
5. No UV rays, no mosquitoes
LED tunnel lamps do not generate ultraviolet rays, so there will not be many mosquitoes around the light source like traditional tunnel lamps. The interior will become more clean and tidy.
6. Voltage adjustable 80V-265V
Traditional tunnel lamps are lit by the high voltage released by the rectifier and cannot be lit when the voltage drops. The LED tunnel lamps can be lit within a certain range of voltage, and the brightness can be adjusted.
7. Save energy and have a longer life
The LED tunnel light is small in size and light in weight, and the shell is encapsulated by epoxy resin, which not only protects the internal chip, but also has the ability to transmit light and concentrate light. The service life of LED is generally between 50,000 and 100,000 hours. Because LED is a semiconductor device, even frequent switching will not affect the service life.
8. Sturdy and reliable, long-term use
The LED tunnel light itself is made of epoxy resin instead of traditional glass, which is more sturdy and reliable. Even if it is hit on the floor, the LED tunnel light will not be easily damaged and can be used with confidence.

How to install tunnel lights?


If the LED tunnel light uses glass, it must be tempered glass. Tempered glass/Reinforced glass Glass with compressive stress on the surface. Also known as tempered glass.

Tempered glass has the following characteristics:
When the glass is damaged by external force, the fragments will be broken into small particles with obtuse angles similar to honeycomb, which is not easy to cause serious harm to the human body.
2.high strength
The impact strength of tempered glass with the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.
3.Thermal stability
Tempered glass has good thermal stability and can withstand a temperature difference three times that of ordinary glass, and can withstand a temperature difference of 300°C.
A major feature of tempered glass is that it is broken into pieces, and it is a burr, which is not easy to cut.
