技术领域technical field

LED光源由于具有低能耗、发光效率高、响应时间快、长寿命、绿色环保，而成为新一代光源，受到各国的高度重视。随着LED发光效率的不断提高，LED光源以其明显的优势正显示出广泛的应用前景，如道路、隧道、景观等照明灯具的应用。LED light source has become a new generation of light source due to its low energy consumption, high luminous efficiency, fast response time, long life, and environmental protection, and has been highly valued by various countries.

与白炽灯、金属卤素灯等发光是360度全方向的传统光源不同的是，LED由其芯片封装的结构决定了发光的多种形式，如朗伯型、侧射型、蝙蝠翼型和聚光型几种。因此在具体应用领域中，为符合该领域的行业或国家标准，需要进行二次光学设计，尤其是大功率LED光源，从而使得LED的光照范围、照度曲线等符合该行业的照明的需求。Unlike incandescent lamps, metal halide lamps and other traditional light sources that emit light in 360-degree directions, LEDs have various forms of light that are determined by the structure of their chip packages, such as Lambertian, side-firing, bat-wing and poly Several types of light. Therefore, in specific application fields, in order to comply with industry or national standards in this field, secondary optical design is required, especially for high-power LED light sources, so that the illumination range and illuminance curve of LEDs meet the lighting requirements of this industry.
在进行LED应用的二次光学设计中，由于发光角度的原因LED的大部分光线是不经反射体而直接照射出去的，这造成LED的光能损失很大。如何有效利用这部分光能是大功率LED光源应用所急需解决的。In the secondary optical design of LED applications, due to the angle of light, most of the light from the LED is directly irradiated without a reflector, which causes a large loss of light energy of the LED. How to effectively utilize this part of light energy is an urgent need to be solved in the application of high-power LED light sources.
