LED tunnel lights for tunnels, workshops, large warehouses, venues, metallurgical and various types of factories, construction, and other places a large area of flood lighting.
LED tunnel lights have the following characteristics
(1) LED tunnel light power consumption, energy saving, LED Tunnel Light compared with the traditional high pressure sodium lamp, its energy consumption savings of more than 40%.
(2) LED tunnel light long life, in the ideal state of 100,000 h, and high pressure sodium lamp and fluorescent tube life of only 10,000 to 30,000 h.
(3) LED tunnel lights with high reliability, low daily maintenance and repair costs, LED Tunnel Light MTBF up to 20,000 h, and high pressure sodium and fluorescent tubes with MTBF less than 10,000 H
(4) Reduce the construction costs of distribution systems (cables, transformers, distribution boxes, bridges, etc.). For long tunnels and long-distance power supply, the proportion of cables and power distribution facilities is particularly large, Lights due to energy saving can greatly reduce the investment in cable and power distribution equipment.
(5) LED tunnel lights can achieve instant start, LED Tunnel Light easy to adjust the brightness, with no flicker, wide start voltage range, etc., can achieve a variety of energy-saving methods, LED Tunnel Light such as according to the road, tunnel traffic flow smart adjustment illumination.
Design of LED tunnel lights
(1) in the tunnel, whether day or night are required to set the basic lighting. When the vehicle enters the tunnel during the daytime, the road surface brightness should gradually decrease, so that the driver's vision has a process of adaptation, the entrance section is divided into the introduction section, LED Tunnel Light the adaptation section and the transition section.
(2) Determine the length (S) of the incoming section, the adaptation section and the transition section, usually determined by the adaptation time of T = 2s according to the vehicle speed (V), which can be estimated by S = VT / 3.6m; Lighting, in the case of two-way traffic and the same entry section.
(3) night entrance is not reinforced lighting, the tunnel should be set up street lighting, brightness is not lower than the basic brightness of the hole 1/2; LED Tunnel Light tunnel should be equipped with emergency lighting, the brightness of not less than 1/10 of the basic brightness.
(4) According to the provisions of JTJ026-90 "Highway Tunnel Design Code", the tunnel entrance lighting section length and the minimum brightness standard of the road are designed as shown in Table 1.
What are the characteristics of LED tunnel lights? Mainly: low power consumption, energy saving, compared with the traditional high pressure sodium lamp, LED Tunnel Light its energy consumption savings of more than 40%; long life, in the ideal state of 100,000 h, high reliability, Daily maintenance and maintenance costs are low.
