A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Example (b):
as shown in fig. 1 and 2, a rainbow projection lamp includes a glass panel 1, a front cover 2, a light source assembly 3, a heat dissipation housing 5, a switching power supply 6, a rear cover 8 and a bracket 10; the glass panel 1 is arranged on the front cover 2, and the front cover 2, the LED light source component 3, the switching power supply 6, the rear cover 8 and the bracket 10 are all arranged on the heat dissipation shell 5; the LED light source assembly 3 comprises a plurality of aluminum substrates 33 provided with a plurality of LED light sources with the same color, lenses 31 corresponding to the LED light sources 21 one by one and a mounting plate 34; the surface of the mounting plate 34 includes a plurality of planes with different angles, and the plurality of aluminum substrates 33 are respectively fixed on the plurality of planes with different angles of the mounting plate.
The surface of the mounting plate 34 comprises planes with a plurality of different angles, each aluminum substrate 33 comprises a plurality of LED light sources with the same color, 32, and the aluminum substrates 33 are respectively fixed on the planes with different mounting plates, so that the angles of the light projected from the LED light sources on each aluminum substrate 33 are different, the overlapping areas of different light spots are reduced, and finally, a relatively clear separated rainbow effect is formed.
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, so that a white light effect can be generated, 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.

The beneficial effect of this embodiment is that three planes can form the basic three-color projection effect requirement of the conventional projection lamp.
As a preferred embodiment, the 3 aluminum substrates 33 respectively include R, G, B color LED light sources, which has the advantage of universal RGB light sources.
As shown in fig. 3, as a preferred embodiment, the included angle α between the first plane 341 and the horizontal plane is 0 ° < α <20 °, and most preferably α =8 °, because if α is too small, the mixed area of the light spots projected by the light sources on the first plane 341 and the light spots projected by the light sources on the second plane 342 is larger, which is not favorable for color separation and thus rainbow effect; if α is too large, the light spot projected by the light source on the first plane 341 and the light spot projected by the light source on the second plane 342 are completely free of a mixed region, and although color separation is achieved, a dark region is generated between the two light spots, which may affect the overall rainbow visual effect.
Meanwhile, on any two adjacent aluminum substrates in the multiple aluminum substrates 33, at the same arrangement position, the horizontal distance h between two adjacent LED light sources is 20mm < h <60mm, preferably h =30mm, because h is too small, the first plane 341 and the second plane 342 are too close to each other, and the mixed area of the light spots projected by the light sources on the first plane 341 and the light spots projected by the light sources on the second plane 342 is larger, which is not beneficial to color separation and thus affects the rainbow effect; and if h is too large, the plane one 341 and the plane two 342 are too far away, so that the light spots projected by the light source on the plane one 341 and the light spots projected by the light source on the plane two 342 are completely free of a mixed region, although color separation is realized, a dark region is generated between the two light spots, and the whole rainbow visual effect is influenced.
As a preferred embodiment, as shown in fig. 4, the lens 31 is an arch lens, and the light-emitting surface is an arch surface 311; the lens 31 is flanked by frosted surfaces 312. The beneficial effect of this embodiment lies in, lets the luminous more concentrated directly over of LED light source, and reduces the interference light of both sides to reduce the interference of both sides interference light to final different colours facula fusion region.
In a preferred embodiment, the LED light sources on the different aluminum substrates 33 are different in color, and may be any of a plurality of different single colors, so that a rainbow effect of different colors can be formed.
In addition, the colors of the LED light sources on the adjacent aluminum substrates 33 are different, and in this embodiment, because the colors of the adjacent light spots are different, a rainbow effect can still be formed; meanwhile, the combination mode of colors is more diversified, such as RGR, BGB or the like, and a rainbow effect with part of the same color bands can be formed.
Example two:
the difference between the embodiment and the first embodiment is that the lamp is added with a waterproof function, and as shown in fig. 1, for those skilled in the art, a waterproof rubber ring I4 is added at the assembly joint between the front cover 2 and the heat dissipation shell 5 of the lamp, so that the waterproof function of the upper half part of the lamp can be realized through simple structural design change; meanwhile, a waterproof rubber ring II 7 is added at the assembly joint between the radiating shell 5 and the rear cover 8, then the external wiring position is changed into a waterproof joint 91, a vent valve 92 is added, and then the waterproof function of the lower half part of the lamp can be realized through simple structural design change; thereby realizing that the whole lamp has waterproof effect.
In the description herein, it is to be understood that the terms "upper", "lower", "right", and the like are based on the orientations and positional relationships shown in the drawings and are used for convenience in description and simplicity in operation, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be constructed in a particular operation, and thus should not be construed as limiting the present invention.
