Light source using modular design program, to achieve the ground illumination and power matching, by increasing or decreasing the number of light sources to meet the different road width and illumination requirements, to meet the city's lighting requirements and not waste electricity.
1. Aluminum radiator and product shape structure design
The appearance design is novel, the structure is ingenious, full of modern atmosphere, in line with the trend of the times, in terms of heat dissipation, we have creatively adopted the air convection type aluminum radiator design scheme, the radiator upper and lower two layers of heat dissipation surface, the middle is connected by eight standing tendons, front and rear ventilation, while the left and right sides have air convection holes, strengthening the air circulation inside the cavity, which is conducive to the discharge of heat, thus effectively improving the LED The heat transfer efficiency of the light source is effectively improved. The above unique heat dissipation design program to ensure that the high-power LED light source in the safe working temperature of 45 ℃ or less.
2, the design of metal bolt type high-power LED light source
The metal bolt type high-power LED light source is designed by our own research and development. In order to improve the stability of the product we use high-quality U.S. imported LED street lamp patented LED light-emitting chip, LED light-emitting chip directly encapsulated in the top of the nut of the metal bolt, the product assembly will be LED metal bolt screwed directly in the aluminum heat sink, thus effectively LED and heat sink closely into one, changing the traditional high-power LED light source with the help of heat-conductive silica gel for The status quo of heat conduction, improve the efficiency of heat transfer between LED and aluminum heat sink, effectively ensure the service life of LED light source more than 60,000 hours. At the same time, the use of Taiwan phosphor, so that the single LED brightness of more than 80 lumens; and a variety of color temperature can be selected to meet the needs of different occasions for different color temperatures.
3, the design of the secondary optical system and light distribution curve
Adopt the unique secondary optical lens module and "strip light spot" light design. The length of the light spot is determined by the LED light angle, so as to reasonably control the distribution of light, avoid the superposition of light waste, reduce the light loss, realize the connection between the light poles with light spots, so that it reaches the national standard brightness index. In order to ensure the ideal road illumination and uniformity at the same time eliminate the LED glare and protect the role of LED light source.
4, the optimal design of the drive circuit
DC 9V-30V or mains AC 84V-264V wide voltage input drive circuit design. Constant current output, so that each high-power LED light source work at a constant rated current, line loss and aging coefficient is small, electrical conversion efficiency ≥ 85%, constant current output to ensure the service life of the LED light source.
5, the LED light source module design
Light source using modular design program, to achieve the ground illumination and power matching, by increasing or decreasing the number of light sources to meet the different road width and illumination requirements, to meet the city's lighting requirements and not waste electricity.
