Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically to a graphene heating lamp. Background Technology

[0002] Most existing heating lamps rely on metal filaments for heat, but this method has several significant drawbacks: First, the materials required for metal filament heating are bulky and heavy, resulting in a thicker and heavier product that is difficult to design in a slim and lightweight manner. Second, metal filaments have slow heat conduction, making it difficult to produce an instantaneous heating effect, and the entire heating process requires considerable energy. Finally, the lifespan and stability of the metal filaments are challenged when operating at high temperatures for extended periods. The metal filaments slowly sublimate at high temperatures, causing them to gradually thin and eventually burn out, thus limiting the overall lifespan of the heating lamp. Utility Model Content

[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0029] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, this application relates to a graphene heating lamp, which is mainly used for installation on the ceiling of a room and belongs to the type of ceiling light. It includes a support plate 100, LED light assemblies 200 are respectively arranged on both sides of the support plate 100, and a graphene heating assembly 300 is arranged between the LED light assemblies 200. The graphene heating assembly 300 includes a top plate 310, which is used for fixed installation on the ceiling of the room. A frame 320 is arranged at the bottom of the top plate 310, and a hollow part 321 is arranged at the bottom of the frame 320. A graphene electric heating film 330 is covered in the hollow part 321, and a starting power supply 340 is installed on the top of the graphene electric heating film 330. The starting power supply 340 is electrically connected to the graphene electric heating film 330 and connected to an external power source (not shown in the figure).

[0030] In this embodiment, during installation, the top plate 310 and the support plate 100 are first fixed to the ceiling of the room. When lighting is needed, the LED light assemblies 200 on both sides of the support plate 100 can be activated to illuminate the outside. However, when heating is needed, the power supply 340 is turned on to start working, connecting an external power source to supply power to the graphene heating film 330. When current flows through the graphene heating film 330, due to the excellent conductivity of graphene, electrons can move freely within it (Brownian motion). When electrons pass through graphene, they will generate intense friction and collisions with atoms, impurities, etc., thereby generating resistance heat in the form of far-infrared radiation. This resistance heat can cause the graphene heating film 330 to heat up, thus producing a heating effect.

[0031] Compared with existing technologies, this application uses graphene electric heating film 330 as the core heating element. Compared with products using traditional heating components, the size can be designed to be thinner and lighter. At the same time, due to the fast thermal conductivity of graphene, it can quickly and efficiently increase the indoor temperature.

[0032] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3As shown, a first connecting portion 322 is formed by bending at the bottom of the frame 320 towards the hollow portion 321. A second connecting portion 323 is provided in the middle of the hollow portion 321, traversing the hollow portion 321. When the graphene heating film 330 covers the hollow portion 321, the first connecting portion 322 and the second connecting portion 323 are fixedly connected to the graphene heating film 330. Since the graphene heating film 330 is a flexible material, the first connecting portion 322 and the second connecting portion 323 can respectively connect and fix the graphene heating film 330 around its perimeter and center, thus preventing it from easily falling off the hollow portion 321 when it covers it.

[0033] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, an L-shaped plate 324 is provided on the second connecting part 323 facing the inside of the frame 320. The starting power supply 340 is fixed on the L-shaped plate 324. When the starting power supply 340 starts working, the external power supply provides electrical energy to the starting power supply 340. The starting power supply 340 transmits electrical energy to the graphene heating film 330 through the L-shaped plate 324 and the second connecting part 323, thereby causing the graphene heating film 330 to heat up and generate a heating effect.

[0034] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, a plurality of ventilation holes 325 are provided on the side wall of the frame 320. Since the graphene electrothermal film 330 dissipates heat both downwards and upwards when it is heated, the ventilation holes 325 on the side wall of the frame 320 allow the heat accumulated in the frame 320 to be dissipated through the air convection effect generated by the ventilation holes 325.

[0035] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, a heat-conducting plate 350 is provided at the bottom of the graphene heating film 330, and the heat-conducting plate 350 covers the bottom of the frame 320. Since the graphene heating film 330 is a soft material, it is easily damaged when in contact with sharp objects. By providing the heat-conducting plate 350, the heat from the graphene heating film 330 can be conducted away during operation, preventing damage to the graphene heating film 330 from external objects during installation or use.

[0036] Furthermore, based on the above embodiments, such as Figure 4As shown, the LED lamp assembly 200 includes a concave housing 210, with a light-transmitting plate 220 covering the bottom of the housing 210. A circuit board 230 is disposed on the housing 210, and several LED beads 231 are mounted on the bottom of the circuit board 230. A through hole 211 is provided on the side wall of the housing 210, through which a wire (not shown in the figure) of an external power supply passes, electrically connecting the external power supply to the circuit board 230. When lighting is needed, the external power supply sends an electrical signal to the circuit board 230, activating the LED beads 231 mounted on the bottom of the circuit board 230, thereby achieving the lighting effect. This is existing known technology, and its detailed principle will not be elaborated here.

[0037] Furthermore, based on the above embodiments, such as Figure 5 As shown, a first mounting groove 110 is provided on both sides of the support plate 100, and a second mounting groove 120 is provided in the middle of the first mounting groove 110. The housing 210 is fixed in the first mounting groove 110, and the frame 320 is fixed in the second mounting groove 120, thereby forming a fixed connection between the LED lamp assembly 200 and the graphene heating assembly 300.

[0038] Furthermore, based on the above embodiments, such as Figure 5 As shown, a plurality of support rods 121 are arranged around the second mounting groove 120. One end of each support rod is fixed to the top plate 310, and the other end is fixed to the support plate 100. Since the top plate 310 is actually connected to the ceiling of the room in this application, and the support plate 100 and the LED light assembly 200 are both suspended from the roof by being connected to the frame 320, the support rods 121 can ensure the stability of the connection between the frame 320 and the second mounting groove 120, preventing the frame 320 from falling out of the second mounting groove 120 and causing the support plate 100 to fall.

[0039] Furthermore, based on the above embodiments, such as Figure 5 As shown, an indicator light 400 is provided on one side of the graphene heating component 300. The indicator light 400 is electrically connected to the power supply 340. When the power supply 340 drives the graphene heating film 330 to start heating, the indicator light 400 lights up, which can remind the user that the product has entered the heating state and that there is no need to touch the heat conduction plate 350 easily.

[0040] Furthermore, this application also provides a second embodiment, which differs from the first embodiment in that hooks 130 are provided at the four corners of the support plate 100. In this embodiment, the application is connected to the ceiling via the hooks 130, instead of via the top plate 310. Therefore, since the distance between the top plate 310 and the ceiling is increased, a cooling fan 311 is provided at the top of the top plate 310. The cooling fan 311 communicates with the frame 320, so that the heat accumulated in the frame 320 can be dissipated by the cooling fan 311, thereby further improving the heat dissipation efficiency of the frame 320.

[0041] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
