Embodiment Construction

[0012] Combine below Figure 1 to Figure 2 The present invention is described in detail:

[0013] A multi-faceted reflective LED color mixing optical path device of the present invention includes an LED lamp board 1 and a super-spherical lens group 2 composed of at least one LED lamp bead, and a solid transparent lens is arranged between the LED lamp board 1 and the super-spherical lens group 2 Regular polygonal light guide column 3, the surface of each side of the light guide column is covered with a reflective film 30, so that the sides of the light guide column can achieve the purpose of total reflection of light. The light column is mixed multiple times through multiple reflections from multiple sides, making the mixed color more uniform and natural, and its color mixing effect is better. The hyper-spherical lens group 2 includes one or two hyper-spherical lenses 20, the function of which is to collect and condense the light with a larger angle emitted through the light g...

Abstract

The invention relates to a multi-surface reflecting LED (light-emitting diode) mixed color light path device, which comprises an LED lamp panel consisting of at least one LED bead and a hypersphere lens assembly, wherein a solid transparent light guide pillar is arranged between the LED lamp panel and the hypersphere lens assembly; each lateral surface of the light guide pillar is covered with a reflective film; the LED lamp panel is covered by the end, close to the LED lamp panel, of the light guide pillar. According to the device with the structure, light emitted by the LED lamp panel is reflected for many times by a plurality of lateral surfaces through the light guide pillar and is mixed for many times, mixed light is uniform and natural in color, and a good color mixing effect is achieved.

Description

technical field [0001] The invention relates to a multi-facet reflective LED color mixing light path device. Background technique [0002] At present, floodlights generally include a light source installed in the lamp tube and a lens assembly sequentially installed on the front side of the light source. The lens assembly generally includes two lenses. The above-mentioned structure is a commonly used structure at present, but there is still color mixing when using LED light sources in the above-mentioned structure. Inhomogeneity, the defect that the utilization rate of light is not high. Contents of the invention [0003] The invention solves the above-mentioned technical problems, and provides a multi-facet reflective LED color mixing light path device with better color mixing effect and higher light utilization rate. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to include an LED lamp board and a super...
