Changhui Lighting Technology Innovation of Solar Photoelectric Conversion

LED street lights are widely used in weak current fields such as signal indication and digital display due to their low power consumption and exceptional service life. However, due to the small opening angle of the traditional LED light source, the high brightness of the spot area, the strong directionality of light scattering, the light source is easy to form light spots, and the light uniformity is not good, which restricts its application in the field of lighting. Through the update and technical improvement of the traditional solar lighting fixture structure, intelligent controller and reflector angle, Changhui Lighting carries out the optimal tilt angle design, so that the advantages of the flat head and the round head complement each other, so that the light is more uniform and the overall brightness is higher. , lower cost, more conducive to application promotion. The column-type and torch-type combined light source structure of the flat-head LED can greatly improve the uniformity and illuminance of the illumination light emitted by the LED combined light source by reasonably controlling the installation inclination angle of the flat-head ultra-high-brightness white light LED. This technology can not only enhance the light efficiency, but also the combined light source consumes only about 4W, and the brightness of the light emitted can reach the brightness of 20W energy-saving lamps or 40W incandescent lamps, which can make more effective use of solar energy. Only the capacity of 12W solar cells is needed, and the 12V/24Ah battery pack can ensure that this LED light source can work continuously and effectively in 5 cloudy and rainy days, and the service life is more than 100,000 hours, which is more than 10 times that of energy-saving lamps. The combination light source specially developed for the field of street lamps; the cross type and the rectangular combination light source, give full play to the advantages of the flat head LED with large opening angle and good light uniformity and the round head LED point area with high brightness, so that the two can learn from each other and maximize the light effect. , Overcome the flat head LED point area brightness is not as good as the round head LED, and the round head LED light uniformity is not as good as the shortcoming of the flat head LED. In terms of the controller, the solar photoelectric conversion technology is used to maximize the collection of electric energy. After the electric energy storage is completed, the battery provides 12V DC power to the light-emitting source, so that the light-emitting source can generate 6500K white light. At the same time, by simplifying the structure of the intelligent controller, the structure is simpler and the failure rate is lower, and technical preparations are made for further cost reduction. Moreover, by detecting the output of the solar cell and the power of the battery, the working state of the system is determined, and the automatic control and intelligent management of the whole system are realized.
