It is necessary to use non-imaging optical design methods to form a uniform spot of a specific size in a specific area, and to maximize the limited light uniformly irradiating the desired area. area, transforming the Lambertian form into a rectangle. At present, in the scheme of using multiple 1W LEDs in series to form a street light source, each LED is equipped with a lens or multiple lenses are connected to form a lens module. For integrated LED street lights, reflectors are mostly used for light distribution. , the former solution has defects such as large light loss, complicated waterproof treatment, inconvenient assembly, and easy aging and yellowing in high temperature environments; in the latter solution, about 50% of the light from the reflective cup is directly emitted, and about 50% % of the light is emitted after reflection, it is difficult to control the uniform distribution of energy, and the light distribution effect is difficult to meet the application requirements.
