We independently developed and designed a metal bolt type high-power LED light source. To improve the stability of the product, we have adopted high-quality LED light-emitting chips imported from the United States. The LED light-emitting chips are directly packaged on the top of the metal bolt nuts. During product assembly, the LED metal bolts are directly screwed onto the aluminum heat sink, effectively integrating the LED and the heat sink, changing the current situation of traditional high-power LED light sources using thermal conductive silicone for heat conduction, Greatly improving the heat transfer efficiency between LED and aluminum heat sink, effectively ensuring that the service life of LED light sources exceeds 60000 hours. At the same time, high-quality fluorescent powder from Taiwan is used to achieve a single LED brightness of over 80 lumens; And there are multiple color temperatures to choose from, which can meet the needs of different occasions for different color temperatures.

Light distribution curve

Adopting a unique secondary optical lens module and a "strip spot" light output design. The length of the light spot is determined by the angle of LED light output, thereby controlling the distribution of light reasonably, avoiding the superposition and waste of light, reducing light loss, and achieving the interconnection of strip light spots between lamp poles, so as to achieve various brightness indicators specified in national standards. It eliminates LED glare and protects LED light sources while ensuring ideal road illumination and uniformity.

drive circuit

Design of a wide voltage input drive circuit for DC 9V-30V or AC 84V-264V. Accurate constant current output ensures that each high-power LED light source operates at a constant rated current, with low line loss and aging coefficient, and an electrical conversion efficiency of ≥ 85%. Accurate constant current output ensures the service life of the LED light source.
