Description
Technical Field
[0001] The utility model belongs to the technical field of dimming glass, and particularly relates to a high-temperature-resistant lighting atomization sheet. Background Art
[0002] Lighting atomization glass, also known as dimming glass or electro-atomization glass, is a special functional optoelectronic glass product. The lighting atomization glass is a sandwich structure formed by sandwiching a liquid crystal film between two layers of glass. By controlling the on-off of the current, the switching between the transparent and opaque states of the glass can be realized.
[0003] In the traditional dimming glass system, there is usually a lack of effective heat regulation and heat protection functions. The traditional dimming glass material is prone to heat accumulation under long-term light irradiation, which affects the use effect of the dimming film and the product life. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a high-temperature-resistant lighting atomization sheet to solve the problems that common dimming glass is prone to heat accumulation, affecting the use effect and product life.
[0005] The utility model realizes the above purpose through the following technical solutions: including tempered glass, a dimming film and a lighting module. A silk screen ink layer, an OCA adhesive layer, and an SCA optical film layer are sequentially arranged and adhered to each other between the tempered glass and the dimming film. A heat-resistant and light-transmitting plate is arranged on one side of the dimming film. The heat-resistant and light-transmitting plate includes cavity glass. A heat-conducting glass tube is horizontally penetrated through the cavity of the cavity glass. An endothermic medium is filled inside the cavity glass.
[0006] Further, through holes are provided at both ends of the cavity glass. The heat-conducting glass tube is located inside the through holes and is hermetically connected. The holes at both ends of the heat-conducting glass tube are exposed to the air. The cavity glass is connected to one side of the dimming film.
[0007] Further, the endothermic medium is a liquid substance with a high specific heat capacity and good light transmittance.
[0008] Further, the lighting module includes a mounting plate and a plurality of lamp heads. The lamp heads are electrically connected to the mounting plate. The light emitted by the lamp heads penetrates through the dimming film and the tempered glass.
[0009] Further, a circuit board is arranged at one end of the dimming film. The circuit board is electrically connected to the dimming film.
[0010] Beneficial Effects: The design of the utility model is reasonable and has the following beneficial effects:
[0011] 1. In the solution of the present utility model, the heat absorption medium inside the heat-insulating and light-transmitting plate blocks and absorbs the heat emitted by the lamp head, reducing the influence of heat on the dimming film. When the dimming glass stops being used, the heat in the heat absorption medium is reversely conducted through the heat-conducting glass tube to the cavity glass to increase the heat dissipation area and accelerate heat dissipation. Moreover, part of the heat can be directly dissipated into the air through the holes in the middle of the heat-conducting glass tube, avoiding heat accumulation and affecting the service life of the dimming film.
[0012] 2. In the solution of the present utility model, the flexibility of light adjustment is improved. By using the dimming film, the light intensity can be adjusted according to actual needs to achieve a foggy light effect, providing a more comfortable and personalized lighting experience for users. While meeting the lighting requirements, it reduces energy consumption and achieves energy conservation and emission reduction.
[0013] 3. In the solution of the present utility model, the cured adhesive layer is used as the adhesion medium between the tempered glass and the dimming film, enhancing the stability of the overall structure and reducing the risk of accidents during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0020] Combined with Figures 1 to 3 shown is a high-temperature-resistant light fogging sheet, which includes a tempered glass 1, a dimming film 2 and a light-emitting module 3. A silk screen ink layer 4, an OCA adhesive layer 5, and an SCA optical film layer 6 are sequentially provided and adhered between the tempered glass 1 and the dimming film 2. A heat-insulating and light-transmitting plate 7 is provided on one side of the dimming film 2. The heat-insulating and light-transmitting plate 7 includes a cavity glass 71, a heat-conducting glass tube 72 is horizontally penetrated in the cavity of the cavity glass 71, and a heat absorption medium is filled inside the cavity glass 71.
[0021] Among them, through holes 73 are provided at both ends of the cavity glass 71. The heat-conducting glass tube 72 is located inside the through holes 73 and is hermetically connected. The holes at both ends of the heat-conducting glass tube 72 are exposed to the air. The cavity glass 71 is connected to one side of the light-dimming film 2. The heat-conducting glass tube 72 can conduct the heat on the cavity glass 71 to the heat-absorbing medium. At the same time, when the light-dimming glass stops being used, the heat in the heat-absorbing medium is reversely conducted to the cavity glass 71 through the heat-conducting glass tube 72 to increase the heat dissipation area and accelerate heat dissipation, and part of the heat can be directly dissipated into the air through the holes in the middle of the heat-conducting glass tube 72.
[0022] The heat-absorbing medium is selected as a liquid substance with a high specific heat capacity and good light transmittance, which is convenient for absorbing the heat emitted by the lamp.
[0023] The light-emitting module 3 includes a mounting plate 31 and a plurality of lamp heads 32. The lamp heads 32 are electrically connected to the mounting plate 31. The light emitted by the lamp heads 32 penetrates the light-dimming film 2 and the tempered glass 1.
[0024] One end of the light-dimming film 2 is provided with a circuit board 21, and the circuit board 21 is electrically connected to the light-dimming film 2.
[0025] Working principle: When the present utility model is in use, after the light-dimming film 2 is powered on, the light emitted by the lamp heads 32 is refracted by the disordered liquid crystals in the light-dimming film 2 to weaken the light to form a foggy light, and passes through the tempered glass 1 and irradiates out.
[0026] The heat-conducting glass tube 72 can conduct the heat on the cavity glass 71 to the heat-absorbing medium to prevent the temperature of the heat-insulating and light-transmitting plate 7 from rising rapidly. At the same time, when the light-dimming glass stops being used, the heat in the heat-absorbing medium is reversely conducted to the cavity glass 71 through the heat-conducting glass tube 72 to increase the heat dissipation area and accelerate heat dissipation, and part of the heat can be directly dissipated into the air through the holes in the middle of the heat-conducting glass tube 72.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
