Abstract

The invention relates to a three-color optical mixing LED point light source device which comprises a shell, a microprism optical board and a circuit base board, wherein the microprism optical board and the circuit base board are fixed in the shell. The three-color optical mixing LED point light source device is characterized in that a plurality of V-shaped ridges which extend along two differentdirections are formed on the microprism optical board; three LED point light sources which can emit a plurality of different single colors are distributed on the LED circuit base board; a light ray emitted by each LED point light source forms four virtual light sources after passing through the microprism optical board; every three LED point light sources emitting different colors form a light source group; and the LED point light sources in each light source group are distributed at a preset distance so that the virtual light sources generated by the LED point light sources in each light source group are laminated. The three LED point light sources in different colors are mixed optically and the color rendering performance of light is enhanced when light luminance is improved.

Description

technical field

[0001] The invention relates to a point light source device, in particular to a three-color mixed light LED point light source device with adjustable light color. Background technique

[0002] LED has the advantages of no mercury, high luminous efficiency, and long service life, and has the tendency to gradually replace traditional lighting sources. The existing LED point light source device is equipped with a micro-prism optical plate to make the LED point light source generate multiple virtual light sources, which reduces the number of LEDs and saves costs without affecting the luminous brightness. However, the monochromatic LED lighting device can only Adjusting the brightness cannot change the light color, which makes it impossible to emit an appropriate light color as the environment changes. In the existing practice, LED point light sources of two colors are usually set up to form a mixed light color suitable for the environment, but the color renderin...
