Problems solved by technology

[0003] The polygonal integrating rod achieves the uniform light effect by reflecting light multiple times in it. The more reflection times, the better the uniform light effect, and the reflective surface of the polygonal integrating rod is a plane, such as figure 1 As shown, the dodging effect of the beam is proportional to the length of the polygonal integrating rod, but the entire optical system has a certain limit on the length of the polygonal integrating rod, which makes the dodging effect of the polygonal integrating rod not good; when the compound eye is used for dodging, Because the light beam entering the compound eye is required to be parallel light, and the light emitted from the LED is divergent, at least two lenses are required to collimate the light and one lens is used to condense the light at the front and rear of the compound eye, which makes the optical element relatively small. many, high cost

Abstract

The invention discloses a dodging device based on a multi-color light beam. The dodging device comprises an integrator rod, which comprises an incident end and an outgoing end, and is used to provide a reflection channel for the light beam; a curved surface reflection member, which is disposed on the integrator rod, and is used to realize the reflection of the light beam. The invention provides an optical system. The dodging effect is good, at low cost.

Description

technical field [0001] The invention relates to the field of optics, in particular to a light homogenizing device and an optical system based on multi-color light beams. Background technique [0002] After the red, green and blue tri-color LEDs are synthesized by optical elements such as filters, they will project light spots containing multi-color patches. The colors are very uneven and cannot achieve ideal white light. Therefore, it is necessary to uniformly light the multi-color beams. The existing dodging methods mainly use polygonal integrating rods or use compound eyes to dodge light. [0003] The polygonal integrating rod achieves the uniform light effect by reflecting light multiple times in it. The more reflection times, the better the uniform light effect, and the reflective surface of the polygonal integrating rod is a plane, such as figure 1 As shown, the dodging effect of the beam is proportional to the length of the polygonal integrating rod, but the entire op...
