Uniform optical reflection method and round LED light source designing method

Abstract

The invention discloses a uniform optical reflection method and a round LED light source designing method. According to the uniform optical reflection method and the round LED light source designing method, a curved reflecting surface and a plane light-out surface are set, an LED light source is arranged between the curved reflecting surface and the plane light-out surface, the positional relation between the curved reflecting surface, the LED light source and the plane light-out surface enables uniform light to be emitted by the plane light-out surface after light emitted by the LED light source is reflected through the curved reflecting surface, the positional relation is set according to a formula, and the LED light source generates a round LED light source through the curved reflecting surface. According to the uniform optical reflection method and the round LED light source designing method, the diffusion film part of the light source is omitted, the light-out rate of the light source is greatly improved, and uniform light emitting is achieved.

Description

technical field [0001] The invention belongs to the field of lighting, and in particular relates to a uniform optical reflection method and a circular LED light source design method. Background technique [0002] Optics and geometric optics and other theories and technologies are very mature and have been widely used in various fields, and the application scope of LED is also expanding. The application of semiconductor lighting and LED lamps has been widely promoted, especially LED backlights and LED flat lights have a large number of applications, but the planar light emitting technology is not yet fully mature, the main reason is the huge difference between the LED electric light source and the planar light, usually Under normal circumstances, the LED light distribution is Lambertian, and the LED luminous angle is between 90° and 120°. There are two main structural forms of flat lights: one is side-firing type, and the other is direct-firing type, and the side-firing type ...

The application of semiconductor lighting and LED lamps has been widely promoted, especially LED backlights and LED flat lights have a large number of applications, but the planar light emitting technology is not yet fully mature, the main reason is the huge difference between the LED electric light source and the planar light, usually Under normal circumstances, the LED light distribution is Lambertian, and the LED luminous angle is between 90° and 120°. There are two main structural forms of flat lights: one is side-firing type, and the other is direct-firing type, and the side-firing type emits light more uniformly. , but the luminous efficiency is extremely low; the direct-type flat lighting has high efficency, but the thickness is relatively large, and its uniformity is poor compared to high luminous efficacy
