[0019] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0020] Figures 1 to 5 It is a structural schematic diagram of the present invention.

[0021] The reference numerals are: lamp housing 1, lamp holder 2, mounting hole 2a, lampshade 3, buckle groove 3a, elastic buckle 4, LED lamp bead 5, metal circuit board 6, connecting wire 7, connector 8, rubber pad 9.

[0022] like Figures 1 to 5As shown, the present invention discloses an ultra-thin integrated stove LED lamp based on an in-mold injection-molded metal card body, comprising a lamp housing 1 and a plurality of LED lamp beads 5 disposed within the lamp housing 1 for emitting light. The use of the LED lamp beads 5 as a lighting fixture not only provides high brightness but also saves energy. The lamp housing 1 of the present invention is assembled from a lamp holder 2 and a lampshade 3, which cover each other. The lampshade 3 is made of translucent white PC material with a ball pressure of 105 degrees and a hot temperature of 550 degrees. When the light is off, the LED lamp beads 5 within the lamp housing 1 should not be visible through the lampshade 3. The lamp holder 2 is made of white PC material and ABS alloy with a ball pressure of 75 degrees and a hot temperature of 550 degrees. To facilitate assembly and disassembly of the lamp housing 1, buckle grooves 3a are formed at both ends of the lampshade 3 during injection molding for quick snap-on installation with the lamp holder 2. The buckle groove 3a is a cavity with a friction slope. Elastic buckles 4 are provided at both ends of the lamp holder 2 to mate with the buckle grooves 3a. When the lampshade 3 is installed, the elastic clips 4 at both ends are elastically expanded by human force, increasing the distance between the clips 4 and snapping into the snap grooves 3a. The elastic clips 4 then utilize their elastic force to secure the lampshade 3 to the lamp holder 2. To remove the lampshade 3, simply pull down on the lampshade 3, forcing the elastic clips 4 to expand and release the lampshade 3. The lamp holder 2 and lampshade 3 of the present invention can be quickly assembled or disassembled without the need for specialized tools or screws. The aforementioned white PC + ABS alloy material is derived from PC / ABS, a blend of polycarbonate and acrylonitrile-butadiene-styrene (ABS). This thermoplastic plastic combines the excellent properties of both materials: the moldability of ABS with the mechanical properties, impact strength, heat resistance, and UV resistance of PC. It is a colorless, transparent granule and is widely used in automotive interior parts, business machines, communications equipment, home appliances, and lighting. PC / ABS is a modified engineering plastic synthesized through mixing. PC is polycarbonate, and ABS is a copolymer of acrylonitrile (A), butadiene (B), and styrene (S). This modified plastic offers superior properties compared to PC and ABS alone, including improved impact resistance, heat resistance, and hardness.

[0023] The lamp holder 2 of the present invention has a mounting cavity formed therein, into which a circuit board is mounted via screws. To improve the heat dissipation performance of the lamp, the circuit board of the present invention is a metal circuit board 6, which is made of a metal substrate with excellent heat dissipation properties. The LED lamp bead 5 is soldered to the circuit in this metal circuit board 6. The LED lamp bead 5 has a heat dissipation metal plate at the bottom. During soldering, the heat dissipation metal plate at the bottom of the LED lamp bead 5 is in close contact with the metal circuit board 6, ensuring that heat from the LED lamp bead 5 can be quickly dissipated to the outside through the metal circuit board 6, thereby achieving the purpose of reducing the lamp bead temperature.

[0024] like Figure 1 As shown, the elastic buckle 4 of the present invention is made of a rectangular metal elastic sheet bent and gripped, and the inner angle of the metal elastic sheet after bending is 102 degrees to 105 degrees. The metal elastic sheet is fixedly set at both ends of the lamp holder 2 by in-mold injection molding.

[0025] In this embodiment, a lead hole is formed in the center of the top surface of the lamp holder 2 of the present invention. A red and blue dual-core connecting wire 7 extends from the lead hole. The red connecting wire 7 is the positive wire, and the blue connecting wire 7 is the negative wire. The lead-out length of the connecting wire 7 is 50 mm. The free end of the connecting wire 7 is connected to a connector 8, which has an internal plug for quick plug-in connection with the power supply.

[0026] In the embodiment, elastic rubber pads 9 are glued to both ends of the top surface of the lamp holder 2 of the present invention. The rubber pads 9 make the LED lamp and the integrated kitchen elastically compacted and connected, which can reduce the vibration of the LED lamp to a greater extent.

[0027] In the embodiment, the top surface of the lamp holder 2 of the present invention has mounting holes 2a symmetrically formed about the center line of the lamp holder 2. The mounting holes 2a are used to fix the lamp holder 2 to the integrated stove using screws.

[0028] The LED lamp for the integrated stove of the present invention has a color temperature of 6000-9000K, a whole lamp attenuation of less than 15% after 1000 hours, a lamp life of more than 25000 hours, an input voltage of 12VDC, and a maximum power of 4.0W.

[0029] The best embodiment of the present invention has been described, and various changes or modifications can be made by those skilled in the art without departing from the scope of the present invention.
