Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 As shown, it is a schematic diagram of the bottom surface of a reflective astigmatism combination structure of a high-power LED light source in the present invention. The reflective astigmatism combination structure 1 is in the form of a rectangular plate as a whole, and the rectangular plate of the reflective astigmatism combination structure 1 is formed by injection molding. Reflective coating. The reflective astigmatism combination structure 1 is provided with a housing 2 , on which there is a fixing screw hole connected to the outside, and on the housing 2 is provided a reflective astigmatism plate 3 .

[0018] Such as figure 2 and image 3 As shown, the reflective diffuser 3 is provided with a plurality of single holes 4, the front of the single holes 4 is rectangular or polygonal, and the cross-section is inverted tap...

Abstract

The invention relates to a reflective light-scattering combined structure of a high-power light-emitting diode (LED) light source. The reflective light-scattering combined structure is provided with a plurality of single holes; the front surface of each single hole is rectangular, polygonal or circular; the cross section of each single hole is reversely conical from the base surface to the end face; and the inner surface of each single hole is at least provided with three layers of arc diffuse reflection surfaces. The inner part of the reflective light-scattering combined structure of the high-power LED light source is rectangular or polygonal, so the beam forms relative reflection; the light rays are repeatedly refracted by the reverse cone and a plurality of layers of arc diffuse reflection surfaces and guided to a light projection direction, so the light uniformity is enhanced; the angle of the reversely conical surface controls an illuminating angle of the light source according to the height and the distance which are needed by illumination so as to increase the light utilization rate; and the LED light sources having the same power and an illuminating distance and a reflective light-scattering board ensure a better multi-layer reflection light-scattering effect, so the uniformity and the light utilization rate of the high-power LED light source in an illuminating light spot region.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a reflective astigmatism combined structure for a high-power LED light source. Background technique [0002] The current high-power LED light source is packaged as a spherical structure, and its irradiation angle is between 70° and 150°. When it is used in the field of high-power lighting, it generally adopts a matrix combination arrangement of multiple LED light sources. However, since the LED is a point light source (the chip is only 1.5mm), the center brightness is high, the uniformity in the irradiation spot area is poor, and the effective light utilization is low. There is an urgent need for a reflective astigmatism combined structure for high-power LED light sources. Contents of the invention [0003] In view of the above problems, the object of the present invention is to propose a reflective astigmatism combination structure for high-power LED light sources, which has better mu...
