LED Tunnel Light 250Watts
1、Module structure provides larger conductive surface for better heat conduction. Lower light decay and longer life of the fixture would be achieved.
2、Aluminum Die-casting body to insure heat dissipation and the same time the long lifespan of the LED Tunnel light.
3、Ballast and other auxiliary lighting parts become unnecessary，enabling to save large amount of lighting maintenance man-hours and cost
4、Human ergonomics light distribution allows uniform illumination
5、Through the CE 、CQC、CCC、ROHS certification

- Q:What are the LED tunnel lamps manufacturers in China doing better?
- Yan Sen lighting technology is based on LED electronic display, LED photoelectric lighting for the main business, set technology research and development, production and processing, product sales, advertising engineering as one of the provincial high-tech enterprises.
- Q:Which brand of LED tunnel light is good?
- Product characteristics:1, imported LED lamp, low light decay, high brightness, long service life2, toughened glass transparent mask, light transmittance, no glare3 、 modular structure, good heat dissipation, easy installation and maintenance4 、 overheating and over-current protection device, lightning protection, safe and reliable.5 、 aluminum alloy shell, plastic sprayed surface, waterproof and dustproof, strong adhesion, uniform color.6, meet the CE/ROHS/3C/UL/CQC standard7, warranty for five years
- Q:Why is the highway tunnel lights two yellow white?
- In fact, not all two yellow white, told the tunnel lighting is set according to the actual situation of tunnel location, specific analysis
- Q:Led turn on the tunnel light, connect the power supply, and then turn on the light system device. Why not turn on the light?
- Compared with outdoor lighting, the tunnel lighting is relatively constant temperature and humidity, and the air flow characteristics of the automobile driving space also make it better for the cooling conditions, but the construction and maintenance are difficult, and the service life is longer. LED is one of the best application fields for tunnel lighting because it has the most remarkable energy-saving effect and the most advantages of directional dense lighting.
- Q:LED what are the tunnel lights?
- Buy LED tunnel lamp, whether the lumen volume first note LED tunnel lamp is higher than 100, light must be less than 3%, the temperature must be less than 60 degrees, the power factor is above 90, recommend that you purchase a LED tunnel lighting lamp, LED tunnel lamp warranty of up to three years, high light rate of patent LED the chip, to ensure high light efficiency, low light decay, can reach 6/1000. The shell adopts high thermal conductivity aluminum material to ensure the long service life of the lamp. Now, there are 300 roads in our country which use the LED tunnel lamp of Yan Sen lamps!
- Q:Comparison of LED tunnel light and high pressure sodium lamp
- 1, simply from the luminous efficiency, LED light effect 90lm/w can not reach the light effect of sodium lamp 120lm/w;2, from the fog performance, the golden light orange fog better performance, of course, can also be replaced by warm white LED;3, from the initial cost of investment, LED lamp price is three to four times sodium lamp;4, from the cost of power saving, taking into account the power factor and other factors, LED lights can save about 60%;5, service life, LED lamp can theoretically reach more than 50000 hours, but by a variety of factor restrictions, such as lamp heat dissipation, the power of life, life can reach 12000 hours of sodium lamp, considering the high cost of maintenance in the tunnel, the LED lamp is more appropriate;Overall, 100WLED lamps can completely replace 200W high pressure sodium (sodium lamp is 250W, but the general specifications) should select the appropriate products from the color temperature, light efficiency, heat dissipation and so on, in addition to do the project is to sell the product, you can do a more detailed comparison of investment plan, product of the initial investment, energy saving the performance and maintenance cost analysis. In the long run, it is only a matter of time before LED replaces gas light.
- Q:LED lights do 3C certification to do those tests, and standards.
- Many LED lamps can not do CCC, can only do CQC, depending on the product, the landlord can combine European standards to see the content of the test!
- Q:Where is the difference between the light distribution and the street light distribution of the LED tunnel light?
- Most of the current market can be divided into the traditional tunnel lamp, light source, light source and LED 2, the production process is not the same, the traditional sodium lamp is divided into 2 parts and the bulb shell, LED complex, light + power + shell. More detailed, including a lot of industrial design in it, what heat radiation structure, light angle, waterproof level, intelligent control, and so on. Need to pay attention to, because the tunnel is not easy to clean, and dust and automobile exhaust combination, easy to adhere to the surface of the lamp, long-term easy to cause attenuation. Therefore, the tunnel lamp dustproof and cleaning should be done well. Most of the LED tunnel lights on the market now change the LED road lamp to tunnel lights.
- Q:Comparison of high pressure sodium lamp and LED lamp in tunnel
- Of course, the power is less than LED high pressure sodium lamp, but the tunnel environment is complex, because of poor air circulation, a large number of exhaust gas expansion accumulation, light propagation ability was significantly inhibited, high pressure sodium lamp can emit yellow light penetration better (anti fog light), to ensure the safety of passing vehicles.
- Q:I would like to ask Chongqing has the strength of LED energy-saving products (such as LED street lights, tunnel lights, etc.) distributors what?
- The mainland is relatively small, do LED lights. Coastal areas are more, I know that there is a company in Shenzhen to do LED lights, I asked the price, LED street lamps, fluorescent lamps are not very expensive
