Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass window technology, specifically to an LED glass window with a heating function. Background Technology
[0002] With advancements in technology, people's demands for comfort and self-expression have increased. Many cars feature eye-catching lights that significantly enhance their aesthetic appeal. However, these lights are often only visible to pedestrians, not passengers inside the vehicle. Furthermore, these lights offer only aesthetic appeal without functional benefits, making them somewhat impractical. Therefore, it is necessary to develop an LED product that can display light on car windows. Considering safety factors, rainwater can obscure the glass surface, obstructing visibility through rearview mirrors and creating a safety hazard. To address this, this invention proposes an LED glass window with a heating function to solve the aforementioned problems. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] Transparent conductive circuits composed of materials such as nano-silver wires and copper metal mesh are fabricated on the surface of a transparent substrate using methods such as 3D printing, photolithography, inkjet printing, screen printing, and nanoimprinting. The transparent substrate uses flexible transparent materials such as PET / PC and is divided into transparent heating circuit areas and transparent LED circuit areas according to different functional areas. A layer of lead electrodes is printed on the edge by printing silver paste and then bonded with metal conductive foil. The metal conductive foil is made of copper / nickel foil. Then, power supply wires are soldered on the surface of the metal conductive foil for power supply. After reflow soldering LED beads on the transparent LED circuit area, the transparent substrate is placed between two pieces of tempered glass with adhesives such as PVB glue.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 3This utility model provides a technical solution: an LED glass window with heating function, including a first tempered glass 1 and a second tempered glass 7, with a PVB adhesive 2 and a transparent substrate 6 disposed between the first tempered glass 1 and the second tempered glass 7. The PVB adhesive 2 is used to fix the transparent substrate 6 between the first tempered glass 1 and the second tempered glass 7. A transparent conductive line is disposed on the transparent substrate 6, which is divided into a transparent heating line area 8 and a transparent LED line area 9.
[0018] On the surface of the transparent substrate 6, methods such as 3D printing, photolithography, inkjet printing, screen printing, and nanoimprinting are employed. These methods have been widely researched and applied in the fields of microelectronics and display technology. Appropriate technologies can be selected according to the needs of the invention to fabricate functional areas with specific grids and sheet resistance. Those skilled in the art can flexibly utilize these technologies to implement the invention according to specific application requirements, creating fully transparent conductive circuits composed of materials such as silver nanowires and copper metal meshes. Furthermore, depending on the different functional areas, the transparent substrate 6 is made of flexible transparent materials such as PET / PC, and divided into transparent heating circuit area 8 and transparent LED circuit area 9.
[0019] The transparent heating circuit area 8 has a break area in the middle to form a uniform circuit. The transparent LED circuit area 9 has ultra-fine lines, which are 5-10um in size. The transparent substrate 6 has silver paste 5 printed on its edge. The silver paste 5 is used to form lead-out electrodes 10. A metal conductive foil 4 is placed on the silver paste 5. A power supply wire 3 is fixedly placed on the metal conductive foil 4. A power connection port 11 is fixedly connected to the power supply wire 3. LED beads are placed on the transparent LED circuit area 9.
[0020] A layer of lead-out electrodes 10 is printed on the edge by printing silver paste 5 and then bonded with metal conductive foil 4, which is made of copper / nickel foil. Then, power supply wires 3 are soldered on the surface of the metal conductive foil 4 for power supply. After reflow soldering LED beads on the transparent LED circuit area 9, the transparent substrate 6 is placed between two pieces of tempered glass with adhesives such as PVB glue 2. This enables LED display to emit light and heat to remove fog. Because of its low resistance and high transmittance, the transparent conductive circuit can be driven with a lower voltage, achieving low energy consumption and high efficiency heating.
[0021] On the surface of the transparent substrate 6, functional areas with different grids and sheet resistances are created using methods such as 3D printing, photolithography, inkjet printing, screen printing, and nanoimprinting. There are two main areas: a transparent heating circuit area 8 and a transparent LED circuit area 9. The transparent heating circuit area 8 has a break section in the middle to form a uniform circuit, ensuring uniform heating of the entire area. This break section design prevents short circuits in the heating circuit, ensuring that the current flows evenly across the entire heating area. This avoids localized overheating and achieves uniform heating of the entire glass surface. The transparent LED circuit area 9 uses ultra-fine lines that do not affect the power supply to the LED chips while maintaining high transmittance. The ultra-fine lines are 5-10µm in size. The circuit reduces resistance and improves current transmission efficiency, thus ensuring a stable power supply for the LED beads. The ultra-fine circuit has less impact on light, so it does not significantly reduce the light transmittance of the glass. This is crucial for maintaining the transparency of the window and ensuring the luminous efficacy of the LED beads. Next, a layer of printed silver paste 5 is printed on the edge to form lead-out electrodes 10, which facilitates subsequent wiring. Then, a metal conductive foil 4 is attached to the surface of the printed silver paste 5 and baked to cure the printed silver paste 5, thus fixing the metal conductive foil 4. Then, the power supply wire 3 is soldered onto the metal conductive foil 4 to lead out. Finally, the transparent substrate 6 is sandwiched between the first tempered glass 1 and the second tempered glass 7 using adhesives such as PVB glue 2. The four sides can be sealed with sealant to extend the service life.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
