In the first embodiment, n =3 is used for illustration.

A method for realizing n-color rainbow effect of a lamp, as shown in fig. 1, 2 and 3, comprises a support plate 10, a light emitting module 2 and a lens 30; the surface of the supporting plate 10 comprises 3 rectangular planes with different angles, namely a plane I11, a plane II 12 and a plane III 13.

The light emitting module 2 comprises 3 light emitting components, namely a first light emitting component 21, a second light emitting component 22 and a third light emitting component 23, wherein the first light emitting component 21 is fixed on the first plane 11, the second light emitting component 22 is fixed on the second plane 12, and the third light emitting component 23 is fixed on the third plane 13.

Light spots projected by the first light-emitting component 21, the second light-emitting component 22 and the third light-emitting component 23 are monochromatic rectangular light spots, the color of the light spot projected by the first light-emitting component 21 is different from that of the second light-emitting component 22, and the color of the light spot projected by the second light-emitting component 22 is different from that of the third light-emitting component 23; and the main optical axes of any two adjacent light-emitting assemblies are deviated in the light-emitting direction.

For convenience of understanding, the colors of the light spots projected by the first light emitting element 21, the second light emitting element 22 and the third light emitting element 23 are set to R, G, B respectively, because RGB is the most widely used color of the lamp.

As shown in fig. 6, 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. 7, after the method is implemented, since the first plane 11, the second plane 12, and the third plane 13 are rectangular planes with three different angles, the first light emitting element 21, the second light emitting element 22, and the third light emitting element 23 are respectively fixed on the first plane 11, the second plane 12, and the third plane 13, and the main optical axes of any two adjacent light emitting elements are in a deviation trend in the light emitting direction. Therefore, in 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, the overlapping region 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 region 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 projection effect can be.

In a preferred embodiment, the second plane 12 is a horizontal plane, the first plane 11 and the third plane 13 are symmetrically distributed on two sides of the second 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 structure, 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 assembly 21, the second light emitting assembly 22 and the third light emitting assembly 23 are structurally differentiated without being changed by a lens.

As one preferred embodiment, as shown in fig. 1, the first light emitting assembly 21 includes a plurality of single-color LED light sources one and a rectangular aluminum substrate 20 for mounting the plurality of LED light sources one 211, the second light emitting assembly 22 includes a plurality of single-color LED light sources two 221 and a rectangular aluminum substrate 20 for mounting the plurality of LED light sources two 221, and the third light emitting assembly 23 includes a plurality of single-color LED light sources three 231 and a rectangular aluminum substrate 20 for mounting the plurality of LED light sources three 231. Preferably, the plurality of single-color LED light sources one 211, the plurality of single-color LED light sources two 221, and the plurality of single-color LED light sources three 231 are linearly and equidistantly arranged on the aluminum substrate. The beneficial effect of this embodiment is that the straight equidistant arrangement is the simplest arrangement for projecting rectangular light spots.

As a preferred embodiment, as shown in fig. 2, the second plane 12 is a horizontal plane, and the first plane 11 and the third plane 13 are symmetrically distributed on two sides of the second plane 12. Meanwhile, the included angle a between the first plane and the horizontal plane is 0 degrees < a <20 degrees, most preferably, alpha =8 degrees, because alpha is too small, the mixed area of the light spots projected by the light sources on the first plane 11 and the light spots projected by the light sources on the second plane 12 is larger, and color separation is not facilitated, so that the rainbow effect is influenced; if α is too large, the light spots projected by the light source on the first plane 11 and the light spots projected by the light source on the second plane 12 have no mixed area, and although color separation is achieved, a dark area is generated between the two light spots, which affects the overall rainbow visual effect.

In one preferred embodiment, as shown in fig. 1 and 2, the lens 30 is an arched lens with frosted surfaces on both sides. The advantage of this embodiment is that this type of lens 30 can project a rectangular spot with less stray light around the rectangular spot.

As one of the preferred embodiments, as shown in fig. 3, the beam angle b of the lens 30 is in relation to a by b = a/2+ k, where k is a constant. Through experiments, preferably, when the light emitting angle of the lens is b =6 °, the most suitable included angle a =8 ° between the plane one 11 and the plane three 13 and the horizontal plane is provided, and then the constant k = 2. When the light-emitting angle of the lens is changed, the calculation can be carried out according to a formula.

In addition, the first plane 11, the second plane 12 and the third plane 13 may be in continuous transition or discontinuous transition, and may be adjusted according to the shape of the housing of the actual lamp and the aperture size of the light projecting glass.

Example two, when n is an odd number:

as shown in fig. 4, a method for realizing n-color rainbow effect of a lamp comprises a support plate 10, a light emitting module, and a lens 30; the surface of the supporting plate 10 includes N rectangular planes with different angles, and the plane one (11), the plane two (12), and the plane N (1N) are sequentially arranged from left to right.

The light emitting module comprises N light emitting components, namely a first light emitting component 21, a second light emitting component 22 and a light emitting component N (2N) which are sequentially arranged from left to right, and the N light emitting components are sequentially and respectively fixed on N rectangular planes on the surface of the supporting plate 10 from left to right.

The light spots projected by the first light-emitting component 21, the second light-emitting component 22, the light-emitting component N (2N) are all monochromatic rectangular light spots, and the colors of the light spots projected by any two adjacent light-emitting components are different; and the main optical axes of any two adjacent light-emitting assemblies are deviated in the light-emitting direction. The beneficial effects of this embodiment lie in for the coincidence region of the rectangle facula that two adjacent light emitting component sent is littleer, more does benefit to and shows independent rainbow effect, if the main optical axis of two arbitrary adjacent light emitting component is the trend of gathering together on the light-emitting direction, then the coincidence region of the rectangle facula that two adjacent light emitting component sent can be very big, and can't show better independent rainbow effect.

The plane (n +1)/2 in the middle is a horizontal plane, and the planes on the two sides of the plane (n +1)/2 are the same in number and are symmetrically distributed. If the planes (n-1)/2 and (n +3)/2 are symmetrically distributed on two sides of the plane (n + 1)/2; the same plane one (11) and plane N (1N) are also symmetrically distributed on both sides of plane (N + 1)/2. The beneficial effects of this embodiment are that the design of symmetric distribution is not only beneficial to the structure assembly, but also makes the projected n rectangular light spots more beautiful in arrangement.

Meanwhile, the included angles between the planes on the left side of the plane (N +1)/2 and the horizontal line become smaller from left to right, namely a1> a2> … > a (N-1)/2, and the planes on the right side of the plane (N +1)/2 are symmetrical to the left side, so that the embodiment structurally trends the light emitting directions of any two adjacent light emitting assemblies in the first light emitting assembly 21, the second light emitting assembly 22, the light emitting assembly N (2N) to deviate and trend without changing through a lens.

In a preferred embodiment, each light emitting assembly includes a plurality of monochromatic LED light sources of the same color and a rectangular aluminum substrate for mounting the LED light sources, and the plurality of LED light sources are regularly arranged on the aluminum substrate. Preferably, the plurality of LED light sources are arranged on the aluminum substrate in a linear and equidistant manner. In practical application, the linear equidistant arrangement of the plurality of LED light sources is the simplest arrangement mode for projecting rectangular light spots.

In a preferred embodiment, the lens 30 is an arcuate lens with frosted surfaces on both sides. The beam angle b of the lens is related to an by b = an/2+ k, where k is a constant.

It is understood that the difference between the present embodiment and the first embodiment is that n in the present embodiment is an arbitrary odd number, and n in the first embodiment is a specific value of 3. But they are conceivable in principle, except that when n >3, the difference is that the included angles between the planes on the left side of the plane (n +1)/2 and the horizontal line become smaller from left to right, namely a1> a2> … > a (n-1)/2, which means that the overlapping area of the rectangular light spots emitted by any two adjacent light-emitting assemblies is smaller so as to display the independent rainbow effect.

For easier understanding, when n =5 is exemplified again here, and the colors of the single-color LED light sources are R, G, B, W, A respectively, the color mixing effect of the conventional projector differs from that of the present technical solution.

As shown in fig. 8, when the conventional projector rgbw a light source is fully bright, the overlapping area 12345 of the R spot 100 projected by the R light source, the G spot 200 projected by the G light source, the B spot 300 projected by the B light source, the W spot 400 projected by the W light source, and the a spot 500 projected by the a light source is very large, and at this time, the 12345 area is a white light effect after rgbw a color mixing, and the R spot 100, the G spot 200, the B spot 300, the W spot 400, and the a spot 500 cannot be displayed clearly and independently.

As shown in fig. 9, after the technical solution is implemented, the R light spot 100 projected by the R light source, the G light spot 200B, B projected by the G light source, the B light spot 300 projected by the W light source, the W light spot 400 projected by the W light source, and the a light spot 500 projected by the a light source, wherein the overlapping area 101 of the R light spot 100 and the G light spot 200 is only located at the edge of the R light spot and the B light spot 300, the overlapping area 203 of the G light spot 200 and the B light spot 300 is also only located at the edge of the B light spot, the overlapping area 304 of the B light spot 300 and the W light spot 400, and the overlapping area 405 of the W light spot 400 and the a light spot 500 is also only located at the edge of the R light spot 100, the G light spot 200, the B light spot 300, the W light spot 400, and the a light spot 500 are relatively clearly.

Example three, when n is an even number:

The plane I (11), the plane II (12), the plane N (1N) are distributed in a left-right symmetrical mode, two planes are arranged in the middle and are respectively a plane N/2 and a plane (N +2)/2, and the beneficial effects of the implementation mode are that the symmetrical distribution design is beneficial to structure assembly, and N projected rectangular light spots are more attractive in arrangement.

Meanwhile, the angle a (n/2) between the plane n/2 and the horizontal line is 0 ° < a (n/2) <20 °, and the angle a (n +2)/2 between the plane (n +2)/2 and the horizontal line is equal to a (n/2) according to the symmetry relation. The included angles between the planes on the left side and the horizontal line become smaller from left to right, namely a1 a2 a … a (N/2), so that the embodiment structurally trends the light emitting directions of any two adjacent light emitting assemblies in the first light emitting assembly 21, the second light emitting assembly 22, and the N (2N) to deviate without changing through a lens.

It is understood that the difference between the present embodiment and the first embodiment is that n in the present embodiment is an arbitrary even number, and n in the first embodiment is a specific value of 3. However, they are conceivable in principle, except that when n is an even number and the left and right are symmetrically distributed, the two planes in the middle are not horizontal planes, but have certain included angles with the horizontal planes, and the included angles between the multiple planes on the left side and the horizontal line become smaller from left to right, that is, a1> a2> … > a (n/2), which means that the overlapping area of the rectangular light spots emitted by any two adjacent light-emitting assemblies is smaller, so as to display the independent rainbow effect.

For easier understanding, when n =4 is exemplified again here, and the colors of the single-color LED light sources are R, G, B, W respectively, the color mixing effect of the conventional projector differs from that of the present technical solution.

As shown in fig. 8, when the conventional projector RGBW light source is fully bright, the R light spot 100 projected by the R light source, the G light spot 200 projected by the G light source, the B light spot 300 projected by the B light source, and the W light spot 400 projected by the W light source overlap each other in a very large area 1234, and at this time, the area 1234 is a white light effect after RGBW color mixing, and the R light spot 100, the G light spot 200, the B light spot 300, and the W light spot 400 cannot be displayed clearly and independently.

As shown in fig. 9, after the technical solution is implemented, the R light spot 100 projected by the R light source, the G light spot 200B, B projected by the G light source, the B light spot 300 projected by the W light source, and the W light spot 400 projected by the W light source, wherein the overlapping area 101 of the R light spot 100 and the G light spot 200 is only located at the edge of the R light spot 100 and the G light spot 200, the overlapping area 203 of the G light spot 200 and the B light spot 300 is also only located at the edge of the R light spot and the W light spot 400, and the overlapping area 304 of the B light spot 300 and the W light spot 400 is also only located at the edge of the R light spot 100, the G light spot 200, the B light spot 300, and the W light spot 400 are relatively clearly and independently displayed.
