As shown in fig. 1-2, in an embodiment of the present application, there is provided an interactive screen lamp with uniform light emission, including:

a substrate 100;

the light source assemblies 200 are arranged on the surface of the substrate 100 and are used for emitting light to the side opposite to the substrate 100;

the reflective support 300 is disposed on the surface of the substrate 100 and distributed around each of the light source assemblies 200, and is configured to collect light emitted from the light source assemblies 200 and reflect the light toward the diffusion film 400;

the diffusion film 400 is arranged side by side with the substrate 100 at intervals, and the diffusion film 400 is supported at one end of the reflecting support 300 away from the substrate 100, and is used for receiving the light reflected by the reflecting support 300 and emitting diffusion light to one side away from the substrate 100.

Specifically, the light source assemblies 200 emit light, and the reflection bracket 300 optically condenses the light emitted from the light source assemblies 200 and reflects the condensed light toward the diffusion film 400, so that the light emitted from each light source assembly 200 is adjusted; after the adjusted light enters the diffusion film 400, uniform diffusion is performed inside the diffusion film 400, and finally diffused light is emitted from the side of the diffusion film 400 away from the substrate 100.

Referring to fig. 3, the reflective support 300 of the present embodiment distributed around each of the light source assemblies 200 first performs preliminary focusing and adjustment to the light so that the light is focused in the sub-regions before reaching the diffusion film 400; and then the light rays which enter the light source assemblies 200 are respectively homogenized and regulated by each block on the surface of the upper diffusion film 400 which is respectively in one-to-one correspondence with the light source assemblies. As shown in fig. 4, the final surface after conditioning of the diffusion film 400 exhibits a more uniform light pattern and a smaller dark space width and area.

The width and the area of the dark space between the light source assemblies 200 are reduced as much as possible, so that the screen which is originally non-uniform in light emission can realize more uniform light emission, and the full light emission filling effect can be realized more easily.

The lamp structure can be arranged on the head or the tail of the vehicle or can be arranged in the interior trim of the vehicle, and can be independently formed into a lamp or integrated into a front lamp or a tail lamp, and the design scheme is not limited.

Referring to fig. 2, in some embodiments, the reflective support 300 includes a plurality of first supports 310 extending in a first direction and a plurality of second supports 320 extending in a second direction; each of the light source assemblies 200 is disposed in a grid formed by intersecting the first and second holders 310, 320.

Specifically, the surfaces of the first support 310 and the second support 320 simultaneously optically condense the light emitted by the light source assemblies 200 and reflect the light toward the diffusion film 400, so that the light can be adjusted and condensed at each position of the annular area surrounding each light source assembly 200, the brightness of the light reaching each area of the diffusion film 400 is basically consistent, the uniformity is improved, the finally presented light is more uniform, and the full luminous filling effect is easier to realize.

Referring to fig. 2, in some embodiments, the second direction is perpendicular to the first direction. When the second direction is perpendicular to the first direction, the first support 310 is a longitudinal support extending along the longitudinal direction, the second support 320 is a transverse support extending along the transverse direction, and the reflective support 300 forms a standard matrix structure, which can be designed in a standardized manner according to different length and width requirements of customers on products, and can be manufactured in a mold opening manner or a stamping manner.

Referring to fig. 1 and 2, in some embodiments, the cross-section of the first and second brackets 310, 320 is isosceles triangle, and the base angle is 70-85 °. The two sides of the isosceles triangle can reflect the light rays emitted by the light source assemblies 200 at two sides at the same angle, which is beneficial to ensuring the uniformity of the light emission at the whole plane position, and the bottom angle is set to be 70-85 degrees, so that the light rays emitted by the light source assemblies 200 can be ensured to be converged and reflected to the upper area of the light source assemblies 200, and the light efficiency can be easily regulated and controlled.

In some embodiments, the material of the first bracket 310 and the second bracket 320 is PC (polycarbonate) or PA66 (polyamide 66 or nylon 66). The PC or PA66 resin material has the advantages of stretching flexibility, easy manufacturing and forming, good optical property and favorable presentation of required light effect.

In some embodiments, the material of the reflective support 300 is a highly reflective material (e.g., a highly reflective nylon material), or the surface of the reflective support 300 is painted to form a highly reflective coating, or the surface of the reflective support 300 is dip-dyed to form a highly reflective coating. By setting the material of the reflective support 300 to be a highly reflective white material, or forming a highly reflective coating (Ag layer, etc.) on the surface of the reflective support 300 by painting or dip-dyeing, the reflective capability of the reflective support 300 can be improved, thereby improving the brightness and uniformity of the light.

In some embodiments, the diffusion film 400 comprises a fresnel-shaped diffusion film.

The basic structure of the diffusion film is that optical diffusion particles (such as sodium iodide crystal blocks, sodium fluoride crystal blocks, crystal and quartz) are coated on two sides of a transparent substrate such as PET, light passes through a diffusion layer taking PET as the substrate and can pass through a medium with different refractive indexes, so that a plurality of phenomena of refraction, reflection and scattering occur on the light, the light can be corrected to form a uniform surface light source with stable chromaticity, the effect of optical diffusion is achieved, and the effect of diffusing the light is achieved.

The diffusion film 400 may be a fresnel-shaped diffusion film, and according to different customer requirements, the diffusion angle X, Y may be evaluated and controlled separately in two dimensions, or the XY diffusion angle may be maintained with the same parameters. The diffusion film 400 is made of transparent material, and the color is designed according to the requirements of customers, so that different light emitting forms are realized.

Referring to fig. 1, in some embodiments, an inner lens 500 is further included, which is disposed on a side surface of the diffusion film 400 remote from the substrate 100.

Specifically, the inner lens 500 is designed to enhance the strength of the diffusion film 400, prevent it from being bent or broken, and ensure the uniformity of the product; as shown in fig. 3, the inner lens 500 may further refract, diffuse and homogenize the light diffused by the diffusion film 400, further reducing the dark space width and area. The diffusion film 400 and the inner lens 500 may be formed as one piece by in-film injection molding, or may be split into two pieces for separate processing.

Referring to fig. 1, in some embodiments, the light source assembly 200 includes:

a light source 210 provided on the surface of the substrate 100;

and a lens 220, covering the light source 210, for primarily diffusing the light emitted from the light source 210.

Specifically, the lens 220 is covered on the light source 210, and can primarily diffuse the light emitted from the light source 210, so that the light emitted from the light source 210 is uniform, and the bright spot of the light source 210 at the central position is prevented from affecting the subsequent light effect.

In some embodiments, the light source 210 is white, yellow, ice blue, or RGB. And can be specifically selected according to the needs, and the application is not limited.
