Our products cover the finished lighting production company, for LED cabinet lights, LED ceiling light, LED? Bulb, LED down light, LED spotlights, LED panel lights, more than a family portrait, and commercial lighting field. ? ?? The company has been engaged in the LED lamps and accessories R & D and production, over the years accumulated a wealth of expertise and production processes. The company independently developed products, but also for customers to design and manufacture products. Our company has high-quality management team capable, advanced equipment, improve the service system. Production speed and quality, every worker to undergo a rigorous training posts, providing the best of products and services for each customer. LED tunnel lights: 1, lead-in: the elimination of "black hole" phenomenon, so that the driver can identify the obstacles in the hole at the brightness of the sector to adapt to the driver's situation will determine the brightness level to the next area needed. CIE calculate the brightness adaptation method is a method of L20, and it calculates the average luminance within enter the start area to the driver's line of sight angle range centered around 20 degrees, the weather and the road. Obviously daytime brightness is higher than at night, so the higher requirements of tunnel lighting during the day. 2. Adaptation section: After entering the tunnel, the driver can adapt quickly and eliminate the "black hole" phenomenon, in the beginning of the brightness requirement remains unchanged and with the outside brightness L20 value and traffic related, later you can make rapid decline in brightness, By the end it could be reduced to 40% of the initial value. 3. TRANSITION: driver gradually adapt to the tunnel interior lighting, brightness declining in the region know the same position with the interior section, but the brightness change rate shall not exceed 1: 3 or the human eye's ability to adapt to the environment is not enough. Of course, at the end of the transition section is three times the brightness of the interior. 4, the basic sections: basic lighting section inside the tunnel, inside the tunnel is usually the longest part. Its brightness level is usually determined by the speed and traffic conditions, usually according to CIE standards. 5 and outlet sections: during the day, so the driver can gradually adapt to the exit of the light, eliminating the "black hole" phenomenon, at night, the driver can see the road outside line and road obstacles, elimination of export at "black hole" phenomenon.
