Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle lamps, in particular to a starry sky lamp with depth effect. Background Art
[0002] With the development of automobile lighting technology, the shapes of lights are becoming more and more novel, and starry sky lights are one of them. Traditional starry sky lights are made by painting the transparent lampshade black, and then laser engraving the lampshade to carve out small light-transmitting holes with random positions and sizes to simulate the starry sky effect. This kind of starry sky light only has a flat visual effect and cannot simulate the depth of the real starry sky. At the same time, in order to simulate the disorder of starlight in the starry sky, a large number of light-transmitting holes with random positions and sizes are required, which increases the difficulty and time of processing. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a starry sky lamp with a depth effect.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a starry sky lamp with a depth effect, comprising a lamp shell, a light source assembly is arranged on the inner side of the lamp shell, a reflector is arranged on the lamp shell outside the light source assembly, the reflector has a plurality of discretely distributed small reflectors, the small reflectors are in an arc structure, a plurality of light-transmitting patterns are arranged on the reflector, and a semi-transparent and semi-reflective mirror is also arranged on the lamp shell outside the reflector.
[0005] Taking production convenience into consideration, further, the reflector is composed of a plurality of small reflectors.
[0006] Furthermore, the small reflectors have different shapes and sizes. The small reflectors have different curvatures and different shapes and sizes, and the distances from the light source to each small reflector are also different.
[0007] In order to ensure the depth visual effect, further, the maximum distance from the light source assembly to the reflector is smaller than the minimum distance from the reflector to the semi-transparent and semi-reflective mirror.
[0008] Furthermore, the positions, sizes and shapes of the patterns are different. With such arrangement, the directions, quantities and brightness of the pattern images will also be different.
[0009] For the convenience of installation, further, the light source assembly is a plate-like structure with point light sources, strip light sources or surface light sources.
[0010] Taking production convenience into consideration, further, the semi-transparent and semi-reflective mirror has a plate-like structure.
[0011] The beneficial effect of the utility model is as follows: the utility model is provided with a reflector with multiple small reflectors, and multiple randomly distributed translucent patterns are arranged on the reflector, the light emitted by the light source on the light source assembly passes through the translucent pattern, passes through the semi-transparent and semi-reflective mirror, part of the light is emitted, and part of the light is reflected back to the reflector, and then the light is reflected again, the light is reflected multiple times between the reflector and the semi-transparent and semi-reflective mirror, and the pattern is also imaged multiple times accordingly, forming a starry sky lamp with a depth effect, and the directions of the pattern imaging are also different; at the same time, due to multiple reflections and multiple imaging, the number of smaller pattern images is far greater than the number of patterns, and the brightness of these images is different, which is closer to the actual starry sky effect.

[0018] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0019] like Figure 1 and Figure 2As shown, a starry sky lamp with a depth effect comprises a lamp housing 1, a light source assembly 2 is arranged inside the lamp housing 1, a reflector 3 is arranged on the lamp housing 1 outside the light source assembly 2, a plurality of discretely distributed small reflectors 31 are arranged on the reflector 3, and the small reflectors 31 are in an arc structure, a plurality of light-transmitting patterns 32 are arranged on the reflector 3, and a semi-transparent mirror 4 is also arranged on the lamp housing outside the reflector 3. Preferably, the maximum distance from the light source assembly 2 to the reflector 3 is less than the minimum distance from the reflector 3 to the semi-transparent mirror 4. Since the bottom surface of the reflector 3 is undulating, the maximum distance from the light source assembly 2 to the reflector 3 is the distance between the light source assembly 2 and the highest point of the bottom surface of the reflector 3; and the minimum distance from the reflector 3 to the semi-transparent mirror 4 is the distance between the lowest point on the upper surface of the reflector 3 and the semi-transparent mirror. Such a configuration can ensure that the time for light to pass through the light-transmitting pattern 32 is short, and ensure that the light is reflected a sufficient number of times between the reflector 3 and the semi-transparent mirror 4.
[0020] like Figure 3 and Figure 4 As shown, the reflector 3 is composed of a plurality of small reflectors 31, and the shapes and sizes of the small reflectors 31 are different. The reflector 3 can be designed as an integral shape, and then cut into a plurality of small modules with different curvatures, and the production according to the small modules is convenient and fast. The position, size and shape of the pattern 32 are different. The pattern 32 is considered at the same time when designing the reflector 3. When it is necessary to apply the front and back film layers during the manufacturing process of the small reflector 31, the light-transmitting pattern 32 can be formed by avoiding the position of the pattern 32. Therefore, there is no need to open a light-transmitting hole separately, which reduces the processing difficulty and shortens the processing time.
[0021] For the convenience of installation, the light source assembly 2 is a plate-like structure with a point light source, a strip light source or a surface light source. It is not required that the light source is directly opposite to the light-transmitting pattern 32, so various forms of the light source are possible. For the convenience of production, the semi-transparent and semi-reflective mirror 4 is a plate-like structure.
[0022] Specific formation process: the light emitted by the light source component 2 passes through the light-transmitting pattern 32 of the reflector 3, passes through the semi-transparent and semi-reflective mirror 4, part of the light is emitted, part of the light is reflected on the reflector 3, and then the light is reflected again. The light is reflected multiple times between the reflector 3 and the semi-transparent and semi-reflective mirror 4, and the pattern 32 is also imaged multiple times, forming a starry sky lamp with a depth effect. Since the reflector 3 is composed of multiple discrete small reflectors 31, the directions of the pattern 32 imaging are also different. At the same time, due to multiple reflections and multiple imaging, the number of images of fewer patterns 32 is far greater than the number of patterns 32, and the brightness of these images is different, which is closer to the actual starry sky effect.
[0023] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
