Description

Technical Field

[0001] This utility model relates to the field of lighting design, and in particular to a lighting fixture. Background Technology

[0002] With technological advancements and rising aesthetic standards, lighting design is no longer limited to meeting basic regulatory requirements; it now demands more uniform and distinctive lighting effects. Three-dimensional lighting effects, compared to single-sided lighting, offer a greater sense of space and technology, making them popular among OEMs.

[0003] In existing automotive lighting solutions, traditional spatial three-dimensional lighting effects use multiple sets of spatially staggered LED lights. Each set of LED lights controls the lighting effect of each layer individually. The spatial three-dimensional effect is achieved by the different depths between LED lights and the differences in brightness between LED groups. This results in increased costs and a larger structure, which seriously affects the overall cost and miniaturization of the product. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a lamp that can achieve a three-dimensional spatial lighting effect, while also reducing costs and meeting the market demand for miniaturization.

[0030] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 4As shown, a lamp includes a light source assembly 10, a light diffusion lampshade 20, a reflective layer 30, a semi-reflective and semi-transparent film 40, and a transparent lampshade 50 arranged sequentially. A patterned groove 31 is formed on the reflective layer (30), and the reflective layer 30 is disposed on the surface of the light diffusion lampshade 20. The semi-reflective and semi-transparent film 40 is disposed opposite to the reflective layer 30, and the semi-reflective and semi-transparent film 40 is attached to the surface of the transparent lampshade 50. Both the light diffusion lampshade 20 and the transparent lampshade 50 are made of light-transmitting material. It should be noted that the light emitted by the light source assembly 10 can pass through the patterned groove 31, that is, the light is diffused through the patterned groove 31. In a preferred embodiment, the patterned groove 31 is formed by laser engraving the reflective layer 30, and the semi-reflective and semi-transparent film 40 and the reflective layer 30 are arranged relatively parallel to each other.

[0032] For better understanding, please refer to [the website / platform] again. Figure 1 and Figure 4 As shown, Figure 1 The diagram provided illustrates the transmission of light emitted from the light source assembly 10 within the luminaire. Figure 4 A schematic diagram of the imaging effect of the lamp in this embodiment is provided. Using a single light source component 10, and through a reflective layer 30 and a semi-reflective film 40, light passing through the light-diffusing lampshade 20 is reflected and transmitted multiple times, achieving a three-dimensional light-emitting effect on a plane. This significantly saves design space, allowing for miniaturization and reducing design costs. Furthermore, the reflective layer 30 has pattern grooves 31, which form the pattern to be displayed by the lamp, improving the clarity of the image.

[0033] To make it easier to understand, the specific way the lamp displays the pattern is as follows: the light emitted by the light source component 10 passes through the light diffusion lamp cover 20 and the pattern groove 31 and shines on the semi-reflective and semi-transparent film 40. Some of the light passes through the semi-reflective and semi-transparent film 40 and the transparent lamp cover 50 to form a pattern, and some of the light is reflected back to the reflective layer 30 through the semi-reflective and semi-transparent film 40. After being reflected by the reflective layer 30, it shines on the semi-reflective and semi-transparent film 40 again. The light undergoes multiple reflections and refractions between the semi-reflective and semi-transparent film 40 and the reflective layer 30 to form a three-dimensional pattern with a multi-layered light emission effect where the brightness gradually decreases.

[0034] In one embodiment, the luminaire further includes a light-shielding plate 60, which is disposed between the light source assembly 10 and the light diffusion lampshade 20 to separate the patterned grooves 31 on the light diffusion lampshade 20. It should be noted that, considering the light source assembly 10 comprises multiple light sources, and the light produced by different light sources has different brightness and wavelengths, separating the patterned grooves 31 by setting the light-shielding plate 60 ensures that the light passing through different patterned grooves 31 is different; that is, different light sources correspond to different patterned grooves 31. The light-shielding plate 60 is used to separate the patterned grooves 31 on the reflective layer 30, preventing light from interfering with each other through different patterned grooves 31, thereby better achieving a dynamic light emission effect.

[0035] In one embodiment, black paint 32 is screen-printed on the edge of the pattern groove 31, and the width of the black paint 32 ranges from 0.5mm to 2mm. By screen-printing black paint 32 on the edge of the pattern groove 31, the pattern formed by two adjacent reflections is divided, the influence of stray light is reduced, and the three-dimensional effect of the overall lamp illumination is increased.

[0036] In one embodiment, the light transmittance of the semi-reflective membrane 40 is 5% to 30%. It should be noted that the light transmittance of the semi-reflective membrane 40 refers to the percentage of light flux passing through the membrane to the percentage of light flux received by the membrane. By controlling the light transmittance of the semi-reflective membrane 40 to 5% to 30%, it is easier to control the reflection of some light rays within the membrane, thereby increasing the three-dimensional effect of the lamp's illumination.

[0037] In one embodiment, the reflective layer 30 is an aluminum-plated layer disposed on the surface of the light diffusion lampshade 20. That is, the reflective layer 30 can be formed by directly spraying the aluminum-plated layer onto the surface of the light diffusion lampshade 20. The aluminum-plated layer has good light reflection effect and is easy to process, which facilitates the formation of the reflective layer 30 on the light diffusion lampshade 20.

[0038] In one embodiment, the thickness of the light diffuser 20 ranges from 1 mm to 3 mm, and the light diffuser 20 is made of a light-transmitting material with a light transmittance of 10% to 50%. It should be noted that the light transmittance of the light diffuser 20 refers to the percentage of light flux transmitted through the light diffuser 20 to the light flux received by the light diffuser 20.

[0039] In one embodiment, the distance between the light diffuser 20 and the transparent lampshade 50 ranges from 5mm to 8mm. If the distance between the light diffuser 20 and the transparent lampshade 50 is too small or too large, the spacing between different layers of the three-dimensional pattern will be too small, resulting in an unclear three-dimensional effect of the pattern.

[0040] In one embodiment, the light source assembly 10 includes a circuit board 11 and an LED lamp 12. The LED lamp 12 is electrically connected to the circuit board 11 and is positioned toward the light diffusion lamp cover 20. The distance between the circuit board 11 and the light diffusion lamp cover 20 is in the range of 15mm to 25mm, thereby ensuring uniform pattern light emission effect.

[0041] Based on the above scheme, the lamp also includes a lamp housing 70, and the circuit board 11, light diffusion lamp cover 20 and transparent lamp cover 50 are all fixedly connected to the lamp housing 70 to improve the structural stability of the lamp.

[0042] Based on the above solutions, please refer to Figure 3As shown, a limiting through hole 111 is provided on the circuit board 11, and a limiting post 71 is provided on the lamp housing 70. The circuit board 11 is mounted on the limiting post 71 through the limiting through hole 111. The cooperation between the limiting through hole 111 and the limiting post 71 securely connects the circuit board 11 to the lamp housing 70.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
