Detailed Description

The invention is further described with reference to the following drawings and specific examples.

In an embodiment, referring to fig. 1-2, an atmosphere lamp assembly with a starry sky lamp effect includes a housing 1, and a light guide plate 5, a first circuit board 6, a second circuit board 2 and a partition plate 3 fixedly mounted with the housing 1; the light guide plate 5 comprises a light inlet surface, a light reflecting surface and a light outlet surface, the light reflecting surface of the light guide plate 5 is provided with a plurality of light reflecting points 51 capable of reflecting light, and the light reflecting points 51 are all laser mesh points formed by laser etching on the light reflecting surface of the light guide plate 5 by a laser dotting machine in the embodiment; the first circuit board 6 is arranged on the light inlet surface side of the light guide plate 5, the first circuit board 6 comprises a microcontroller and a plurality of first LED lamp modules connected with the microcontroller, light sources of the first LED lamp modules are attached to the light inlet surface of the light guide plate 5, emitted light enters from the light inlet surface and is emitted from the light outlet surface after being reflected by the light reflecting points 51; the light guide plate 5 is provided with a plurality of through holes 52 penetrating the light reflecting surface and the light emitting surface, and all or part of the through holes 52 in each through hole 52 are linearly arranged and spaced by a preset distance; the isolation plate 3 is arranged on the reflecting surface of the light guide plate 5, the lower end surface of the isolation plate 3 is provided with a plurality of light-isolating columns 31 which are matched and arranged with the through holes 52 in a one-to-one correspondence mode, and light-emitting holes 32 which penetrate through the isolation plate 3 are formed in the light-isolating columns 31; the isolation plate 3 can isolate light from entering and exiting between the light guide plate 5 and the light outlet hole 32; the transparent plug 4 is further fixed in the light-emitting hole 32, and the transparent plug 4 can seal the light-emitting hole 32 to achieve the effects of dust prevention and soft and uniform light. The second circuit board 2 is arranged on the isolation board 3, and the circuit of the second circuit board 2 is communicated with the first circuit board 6 through a flat cable or a connector, so that the microcontroller can also control the components of the second circuit board 2; the second circuit board 2 comprises a plurality of second LED lamp modules 21 connected with the microcontroller, the second LED lamp modules 21 correspond to the light outlet holes 32 in a matched mode, and light rays emitted by the second LED lamp modules 21 are emitted from the light outlet holes 32; the microcontroller may independently control the brightness and color of each second LED lamp module 21.

The visual effect that this embodiment atmosphere lamp assembly finally appears includes starry sky lamp effect, meteor effect and starlight scintillation effect, wherein:

the starry sky lamp effect is realized through the light guide plate 5, and the light that a certain amount of first LED lamp module sent gets into from the light guide plate 5 side, takes place diffuse reflection and refraction when shining at reflection of light point 51, finally jets out from the plain noodles, and a reflection of light point 51 just is equivalent to a luminous star. The size, number and position of the star light depend on the size, number and position of the preset reflective dots 51 on the reflective surface of the light guide plate 5.

The meteor effect is realized by the second LED lamp modules 21 which are arranged in a straight line, and because the second LED lamp modules 21 can be independently controlled by the microcontroller, when the second LED lamp modules 21 on the straight line are sequentially lightened on and extinguished or gradually darkened after being lightened, the visual effect presented to the user is like the effect of meteor stroking; due to the presence of the partition plate 3, light in the light guide plate 5 does not enter the light exit holes 32 to affect the light emitted from the second LED lamp module 21.

The starlight flickering effect is realized through the second LED lamp module 21, different from the light emitted by the light guide plate 5, the light guide plate 5 emits a plurality of light spots which can only be simultaneously turned on or off, and the effect that part of starlight can twinkle cannot be simulated; the second LED lamp modules 21 can be independently controlled by the microcontroller, so that the brightness of the plurality of second LED lamp modules 21 can be completely controlled by the program, and the effect of starlight flickering is realized; this method has a great drawback only: if a relatively realistic effect is to be achieved, the flickering star light should be scattered throughout the sky, rather than being confined to a certain area, and thus, the second circuit board 2 should be made large; the current area of the automobile ceiling is about 1.5 to 2 square meters, the light guide plate 5 is good in cost, but the second circuit board 2 is large in size, difficult to manufacture and obviously unrealistic, and even if the size can be high, the cost is high.

In order to better achieve the effect of starlight flickering, the embodiment further comprises an optical fiber lamp module connected with the microcontroller; the microcontroller can independently control the brightness and the color of the optical fiber lamp module; the optical fiber lamp module comprises a light source device and a plurality of optical fiber wires with head ends fixed at the light source device; the light guide plate 5 is provided with a plurality of fixing holes for fixing the tail ends of the optical fibers, and the fixing holes also penetrate through the light guide plate 5; the terminal side of optic fibre silk has the light shield layer, and the length of light shield layer is greater than the thickness of light guide plate 5, and light can be kept apart to the light shield layer and pass in and out between light guide plate 5 and fixed orifices. The optical fiber lamp module has the advantages that the length of the optical fiber filament can be adjusted at will, so that the optical fiber filament can be conveniently fixed at any position of the light guide plate 5; secondly, the twinkling stars are only interspersed, and the number is not large, so that the cost is not increased too much.

Compared with the all-optical fiber star-sky-top scheme in the background art, the atmosphere lamp assembly is simple and convenient to install, lower in cost and easier to popularize in middle and low-end vehicles; compared with a pure acrylic light guide plate star empty top scheme, the light guide plate star empty top scheme has a meteor crossing effect and a starlight flickering effect, and is better in embodiment sense for users.
