First, aluminum radiator and product outline structure design Â
The design is novel, the structure is clever, and it is full of modern flavor. It conforms to the trend of the times. In terms of heat dissipation, we have creatively adopted the air convection cavity aluminum radiator design scheme. The radiator has two upper and lower heat dissipation surfaces, and the middle is connected by eight vertical bars. , Before and after permeation, both sides of the air convection holes on both sides, to strengthen the air circulation inside the cavity, is conducive to the discharge of heat, thus effectively improving the LED light source heat transfer efficiency. The above unique heat dissipation design ensures safe operation of high-power LED light sources below 45°C. Â
Second, the design of metal bolt type high power LED light source Â
Independently researched and developed a metal bolt type high power LED light source. In order to improve the stability of the product, we use high-quality imported from the United States Â
The patented LED light-emitting chip of the LED street lamp directly encapsulates the LED light-emitting chip on the top of the nut of the metal bolt. When the product is assembled, the LED metal bolt is directly screwed on the aluminum heat sink, thereby effectively integrating the LED and the radiator. As a whole, the traditional high-power LED light source has changed the status of heat conduction with the aid of thermal conductive silicone, which greatly improves the heat transfer efficiency between the LED and the aluminum heat sink, and effectively ensures that the service life of the LED light source is greater than 60,000 hours. At the same time using Taiwan's high-quality phosphor, so that a single LED brightness to 80 lumens or more; and a variety of color temperature can be selected to meet different occasions for different color temperature needs. Â
Third, the design of the secondary optical system and light distribution curve Â
Unique secondary optical lens module and "ribbon spot" light design. The length of the light spot is determined by the LED light exit angle, so that the distribution of light can be controlled reasonably, light waste can be avoided, light loss can be reduced, and the strip light spots can be connected between the light poles to meet the requirements of national standards. The brightness indicators. The LED glare and the protection of the LED light source are eliminated while ensuring ideal road illumination and uniformity. Â
Fourth, the optimal design of the drive circuit Â
DC 9V-30V or commercial AC 84V-264V wide voltage input drive circuit design. Accurate constant current output makes each high-power LED light source work under constant rated current. The line loss and aging coefficient are small, and the electrical conversion efficiency is ≥85%. The accurate constant current output ensures the service life of the LED light source. Â
Fifth, the modular design of LED light source Â
The light source adopts a modular design scheme to achieve the best matching of ground illumination and power. By increasing or decreasing the number of light sources to meet different road width and illumination requirements, the purpose of meeting the city's lighting requirements without wasting energy is achieved.
