High lighting efficiency of solar garden lights

The high lamp efficiency of solar garden lights provides convenience for life. The design of solar garden light reflectors is mainly to use various quadratic curves to form reflector busbars independently or in combination, and to coat the reflective surface with silver aluminum or chrome with high reflectivity. ; and other materials. In this structure, nearly 50% of the light is directly emitted, and the light reflected by the reflective surface can also reduce the absorption loss through the control of the reflectivity of the film layer, so the reflective device can achieve high lamp efficiency. The secondary optical design combining reflection and refraction simply uses the structure of the aspheric reflector. Due to the limited envelope angle, the solar garden light will swirl around the lens; it cannot be effectively used. Therefore, it is necessary to add a reflector to the structure of the lens to fully and effectively collect and utilize the flux of LED street lights and garden lights. An aspherical fly-eye lens is also an effective structure for generating a uniform light spot. The primary optical device using a fly-eye lens is also composed of a reflector and a lens. The reflector collects the light and modulates it into a relatively parallel beam, which is then converted by the fly-eye lens. The light radiates out at a certain angle; the structure mechanism is clear, and the uniform and comfortable lighting effect is achieved. ; In the field of commercial lighting, the optical software commonly used in China is mainly divided into two categories, lighting engineering design software and light distribution design of lamps.
