Charging station lighting problems
       The highway toll station uses basically is high pressure sodium lamp, high-pressure sodium lamp for the reason of high brightness, long has been main lighting lamp road lighting, however, its high current, high power, high energy consumption to energy and environmental protection, and caused huge waste. Fourth generation lighting - solid state lighting (LED lighting) after decades of research and exploration, has become a universal recognition and promotion of the world's highly efficient energy-saving lighting. China's Ministry of science and Technology launched the Ten City million semiconductor lighting application demonstration city plan, the plan covers Beijing, Shanghai, Shenzhen, Wuhan and other 21 domestic developed cities.
       LED lighting in addition to the green environmental protection, the biggest bright spot is high energy-saving, long-life, LED lighting the actual energy saving is about 60% of the high pressure sodium lamp, today in the development of science and technology has matured, LED lighting to replace high pressure sodium lighting has become a necessity.

The LED lamp and high pressure sodium contrast

1, energy conservation: the white LED luminous efficiency is about 90 Im/W, actual lighting effects tested, than the way for the use of high-pressure sodium lamp integrated energy-saving 50% ~ 60%. With the rapid development of LED technology, LED industrial and mining lamps have a huge potential for energy saving.

2, the maintenance cost is low: high power LED light source can be normal with 4 ~ 5 years without replacement, and traditional high-pressure sodium lamp average a year and a half to replace a, greatly reduce the maintenance cost, save human resources.

3, the color of good: LED color index is high, can meet the needs of different occasions of the color temperature of, the road looks brighter, feeling more comfortable, the driver also feel more secure; while the narrow spectrum of high pressure sodium lamp, color difference and road feel dim.

4, green environmental protection: light source do not lead, there is no pollution of the environment, from the production process to use until scrapped almost devoid of pollution, realize the real meaning of green environmental protection and energy saving lighting, but does not produce electromagnetic interference (high pressure sodium lamp contains mercury and xenon elements, the electronic ballast will produce electromagnetic interference), non polluting to the power grid, power factor is greater than or equal to 0.9, harmonic distortion is less than or equal to 20%, EMI with global index.

5, the protection function: LED lamp using light-emitting semiconductor chips, LED light source no filament and glass enclosure, no fragmentation of the traditional lamp, strong earthquake, using advanced packaging technology of high reliability, adequate protection of the service life of the LED lamp.

6, high safety factor: the characteristics of the DC low voltage work compared to the traditional lamps more safe and reliable, LED lights the required voltage, current smaller, less heat, no security risks.

Application effect of LED lamps
        According to the needs of users, the highway toll station three roads, each road calyceal 250W high pressure sodium lamp, a total of six lamp 250W high pressure sodium lamp replacement for six lamp 120WLED miner's lamp:

       Through the above data comparison, we can led mining lamp illuminance were found to be far above the high-pressure sodium lamp, led mining lamp in the power-saving effect is better than high voltage sodium lamp saves 60%. This is no additional maintenance costs often HPS and green environmental advantages.

Charging station special popularization light LED industrial and mining lamp

1, thermal design by superconducting aluminum radiator, using advanced phase-change heat transfer ways to enhance the heat dissipation capability, with temperature integration;

2, power supply design, anti surge absorption circuit, load protection, open circuit protection, EMC circuit design, power efficiency of more than 90%, power factor of up to 95;

3, LED light source: LED lamp with integrated light source of imports, high light efficiency, high color rendering index, longer life; optical design using special optical design, uniform light, no glare; energy saving and environmental protection without mercury and other heavy metals and UV.

4, the product has passed UL, TUV, CE, SAA, RoHS certification.

Replacing measures: toll station in the field survey, we found that now the high-pressure sodium lamp only very weak light according to the toll station into the station and a station outside the place, after the installation of the LED mining lamp, lighting distance could be far? Provided by the Division I led mining lamp with a patented rectangular prescription lens. Through the light distribution lens, the light distribution curve was batwing, effective control of the light emitting angle, the reasonable control of the beam shape the the effective optical illumination range light is more uniform, and the lighting effect is improved, reducing glare.

The scheme can also be applied to the workshop, workshop, warehouse, highway toll stations, gas stations, large supermarkets, exhibition halls, stadiums, construction sites, mining areas and other places of lighting. Popularity light is led lighting lamps professional supplies manufacturers, home lighting and commercial lighting / engineering lighting solutions experts to solve, continue to flip to consult it.
