Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lampshades, in particular to a high-brightness multi-layer composite film used for lampshades. Background Art
[0002] At present, the lampshades on general lamps are made of plastic, glass, acrylic, etc. When light passes through the lampshade, it will reduce the light transmission and reduce the brightness. Moreover, after these materials are used for a long time, they will be stained by dust and other dirt, which will reduce the brightness of the lamp. Therefore, the lampshade needs to be cleaned regularly, and it is difficult to clean these materials after they are stained with dirt. Therefore, it is necessary to improve this. Summary of the invention
[0003] The utility model aims at the defects in the prior art that the lampshade reduces the brightness of the light source, and provides a new high-brightness multi-layer composite film applied to the lampshade.
[0004] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:
[0005] A high-brightness multi-layer composite film used for lampshades comprises a honeycomb micro-permeable structure, a first substrate layer, a first bonding adhesive layer, a prism layer, a second substrate layer, a diffusion layer, a second bonding adhesive layer, a high-fog diffusion layer, and a third substrate layer, which are sequentially connected from top to bottom.
[0006] The light first passes through the high fog diffusion layer to make the brightness of the light uniform. The honeycomb micro-transparent structure and the prism layer are bonded together to enhance the overall brightness of the light source. The three-layer base material increases the hardness of the material, making it more convenient to use.
[0007] Preferably, in the high-glow multi-layer composite film used as a lampshade, the honeycomb micro-transparent structure is composed of a combination of micro-lenses arranged in a honeycomb pattern on the first substrate layer.
[0008] The upper honeycomb micro-transparent structure can concentrate light, improve light utilization, and maximize the brightness of the light source.
[0009] Preferably, in the high-glow multi-layer composite film used for lampshades, the microlens is a hemispherical structure.
[0010] The hemispherical microlens improves the scratch resistance of the entire membrane, ensuring that the overall performance of the product will not decline.
[0011] Preferably, in the high-glow multi-layer composite film used for lampshades, the diameter of the microlenses ranges from 26 μm to 50 μm, and the height ranges from 11 μm to 23 μm.
[0012] The micro lens can make the film have higher brightness, improve the utilization rate of the light source, and make the light source of the lamp brighter.
[0013] Preferably, in the high-glow multi-layer composite film used as a lampshade, the thickness of the first substrate layer is 100 μm-250 μm.
[0014] Selecting a polyester film with a thickness of 100 μm-250 μm as the first substrate layer can make the overall diaphragm harder and facilitate product replacement and use.
[0015] Preferably, in the high-glow multi-layer composite film used as a lampshade, the prism layer includes alternately arranged first prisms and second prisms, the bottom side L1 of the first prism cross section is 75 μm long, the bottom side L2 of the second prism cross section is 75 μm long, and the height of the first prism is higher than the height of the second prism.
[0016] A prism structure with one high and one low is adopted, in which the height of the first prism is higher than the height of the second prism, and the overall brightness of the product can be improved by concentrating the light source.
[0017] Preferably, in the high-glow multi-layer composite film used for lampshades, the haze of the diffusion layer is 3%-8%, and the thickness of the diffusion layer is 3μm-5μm.
[0018] The haze of the diffusion layer is 3%-8% and the thickness is 3μm-5μm, which can make the light source have better transmittance. The diffusion particles distributed in the diffusion layer can improve the utilization rate of the light source and have the effect of uniform light.
[0019] Preferably, in the high-glow multi-layer composite film used for lampshades, the haze of the high-fog diffusion layer is 80%-95%, and the thickness of the high-fog diffusion layer is 3μm-10μm.
[0020] The high fog diffusion layer allows the light to be reflected and refracted at different angles after entering the film, which can achieve the effects of high light transmittance and high diffusion.
[0021] Preferably, in the high-glow multi-layer composite film used as a lampshade, the thickness of the third substrate layer is 100 μm-250 μm.
[0022] Selecting a polyester film with a thickness of 100 μm-250 μm as the third substrate layer can make the overall diaphragm harder and facilitate product replacement and use. BRIEF DESCRIPTION OF THE DRAWINGS
