In the first embodiment, the first monochromatic light source 211, the second monochromatic light source 221 and the third monochromatic light source 231 are different in light emitting color.
An LED light source component for realizing a three-color rainbow effect comprises a supporting plate 1, a first light-emitting module 21, a second light-emitting module 22, a third light-emitting module 23 and a lens 3; the surface of the supporting plate 1 comprises three planes with different angles, namely a plane I11, a plane II 12 and a plane III 13;
the first light-emitting module 21 comprises an aluminum substrate 20 and a plurality of monochromatic light sources one 211 arranged on the aluminum substrate, the second light-emitting module 22 comprises an aluminum substrate 20 and a plurality of monochromatic light sources two 221 arranged on the aluminum substrate, and the third light-emitting module 23 comprises an aluminum substrate 20 and a plurality of monochromatic light sources three 231 arranged on the aluminum substrate; the arrangement rules of the plurality of single-color light sources I211, the plurality of single-color light sources II 221 and the plurality of single-color light sources III 231 are the same;
the first light-emitting module 21, the second light-emitting module 22 and the third light-emitting module 23 are sequentially fixed on the surfaces of three different angle planes of the supporting plate 1 through the aluminum substrate 20, so that the angles of light rays projected from the first light-emitting module 21, the second light-emitting module 22 and the third light-emitting module 23 are different, the overlapping areas of three light spots are reduced, and a relatively clear separated rainbow effect is finally formed.
In a preferred embodiment, the first monochromatic light source 211, the second monochromatic light source 221 and the third monochromatic light source 231 are different in light emission color. For easier understanding, the monochromatic light source one 211 is defined as an R light source, the monochromatic light source two 221 is defined as a G light source, and the monochromatic light source three 231 is defined as a B light source.
As shown in fig. 5, when the RGB light source of the conventional projector is fully bright, the overlapping area 1230 of the R light spot 100 projected by the R light source, the G light spot 200 projected by the G light source, and the B light spot 300 projected by the B light source is very large, and at this time, the area 1230 is a white light effect after RGB color mixing, and the R light spot 100, the G light spot 200, and the B light spot 300 cannot be displayed clearly and independently.
As shown in fig. 6, after the technical solution is implemented, the R light spot 100 projected by the R light source, the G light spot 200B projected by the G light source, and the B light spot 300 projected by the light source, wherein the overlapping area 101 of the R light spot and the G light spot is only located at the edge of the R light spot and the G light spot, and the overlapping area 203 of the G light spot and the B light spot is also only located at the edge of the G light spot and the B light spot, that is, the R light spot 100, the G light spot 200, and the B light spot 300 are relatively clearly and independently displayed, so that the rainbow light projecting effect.
In a preferred embodiment, the first plane 11 and the third plane 13 are symmetrically distributed on two sides of the second plane 12, the second plane 12 is a horizontal plane, and the first plane 11 and the third plane 13 are outward inclined planes. The beneficial effect of this embodiment is that the second plane 12 is designed as a horizontal plane to facilitate the installation of the light emitting module or LED light source assembly, and the first plane 11 and the third plane 13 are designed as outward inclined planes, so that the light emitting directions of the first light emitting module 21, the second light emitting module 22 and the third light emitting module 23 are structurally differentiated without being changed by a lens.
As shown in fig. 3, as a preferred embodiment, the angle α between the first plane 11 and the horizontal plane is 0 ° < α <20 °, and most preferably α =8 °, because α is too small, the mixing area of the light spot projected by the first monochromatic light source 211 on the first plane 11 and the light spot projected by the second monochromatic light source 221 on the second plane 12 is larger, which is not favorable for color separation and thus affects the rainbow effect; if α is too large, the light spot projected by the monochromatic light source one 211 on the plane one 11 and the light spot projected by the monochromatic light source two 221 on the plane two 12 have no mixed region, and although color separation is achieved, a dark region is generated between the two light spots, which affects the overall rainbow visual effect.
Meanwhile, in the monochromatic light source I211, the monochromatic light source II 221 and the monochromatic light source III 231 which are at the same relative position, the horizontal distance h between any two adjacent monochromatic light sources is 20mm < h <60 mm. Preferably, h =30mm, because h is too small, the plane one 11 and the plane two 12 are too close to each other, and the mixed area of the light spot projected by the monochromatic light source one 211 on the plane one 11 and the light spot projected by the monochromatic light source two 221 on the plane two 12 is larger, which is not beneficial to color separation and affects the rainbow effect; and if h is too large, the plane one 11 and the plane two 12 are too far away, so that the light spot projected by the monochromatic light source one 211 on the plane one 11 and the light spot projected by the monochromatic light source two 221 on the plane two 12 are completely free of a mixed area, although color separation is realized, a dark area is generated between the two light spots, and the whole rainbow visual effect is influenced.
In a preferred embodiment, the plurality of first monochromatic light sources 211, the plurality of second monochromatic light sources 221, and the plurality of third monochromatic light sources 231 are all arranged in a straight line on the respective aluminum substrate and are parallel to each other. This embodiment has the advantage that a rainbow effect of a linear stripe pattern can be achieved.
As a preferred embodiment, as shown in fig. 4, the lens 3 is an arch lens, and the light-emitting surface is an arch surface 31; the lens 3 is flanked by frosted surfaces 32. The beneficial effect of this embodiment lies in, let the luminous more concentrated directly over of light source, and reduce the interference light of both sides to reduce the interference of both sides interference light to final different colours facula fusion region.
Preferably, the longitudinal light-emitting angle of the arched surface 31 of the lens 3 is 100-180 °, which has the advantage of enabling the length of the light spot projected by each monochromatic light source to be larger.
Preferably, the lens 3 has an arcuate surface 31 with a lateral light-emitting angle of 6 ° to 20 °. The embodiment has the advantages that the width of each light spot projected by each monochromatic light source is narrower, the separation display of each light spot is more facilitated, and the layered rainbow effect is easier.
Example two: the emission colors of the first monochromatic light source 211 and the third monochromatic light source 231 are the same, but different from the emission color of the second monochromatic light source 221.
As those skilled in the art can understand, the difference between the second embodiment and the first embodiment is only different from the color of the monochromatic light source, and the others are the same, so the description is not repeated again.
For better understanding, the monochromatic light source one 211 and the monochromatic light source two 221 are both defined as R light sources, the monochromatic light source three 231 is defined as G light sources, and the rainbow effect formed at this time is an RGR rainbow, because the colors of adjacent light spots are different, and thus a layered rainbow effect can still be formed.
