1. Light spot: refers to the figure formed by the light on the illuminated object (usually in a vertical state) (it can also be understood literally).
2. According to the lighting design requirements of different venues, there will be different light spot requirements. Therefore, LEDs often need to go through secondary optical designs such as lenses and reflectors to achieve the design effect.
3. According to the combination of LED and supporting lens, there will be different shapes, such as circle and rectangle. At present, circular light spots mostly appear in commercial lighting fixtures, while rectangular light spots are mainly required for LED street lamps.
4. For different light spot design requirements, you need to deal with both LED and secondary optics. LEDs have various specifications and shapes, and each specification will have corresponding lenses and reflectors of various specifications. Comprehensive evaluation and test
At present, there are many manufacturers of LED lamps on the market. I believe that everyone has to face a thorny problem: the dazzling and light spot of LED and the problem of strong light direction. Three factors that should be considered for exterior recessed lighting For LED inground Uplights, the key technology is to control the brightness uniformity of in ground outdoor lighting. Generally speaking, to improve the brightness uniformity, the thickness of the mixed light cavity must be increased to avoid Increasing the optical path can achieve the best light mixing, but it will inevitably increase the overall thickness of the lamp and increase the light loss of the lamp. For outdoor uplights, a diffuser plate is used to atomize and diffuse the LED electric light source.Such as our Ground floor lights GL150. The principle is that there is a partial overlap between the circular diffused light spot formed on the diffuser plate by each LED and the diffused light spot, so that we can achieve the effect of uniform atomization from the front of the lamp. To achieve this effect, we need to consider two factors. First, what kind of LEDs are used, different LEDs form different light spots on the diffuser plate, and we try to choose LEDs with a large light-emitting angle. Second, the distance between the diffuser plate and the LED, the smaller the distance, the smaller the light loss, but the LED bright spot will appear when the distance is small. Therefore, when designing outdoor stainless steel lights, it is necessary to achieve uniformity, no light points, and less light loss as much as possible. The above factors must be considered.
