Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example 1 As attached Figure 1-2 As shown, this embodiment provides a lighting fixture, including a lamp holder 1, a PCB board 2, and LED beads 3 disposed on the PCB board 2. The lamp holder 1 has a fixing hole 16, which can be fixed to a household appliance using screws. The lamp holder 1 has a receiving groove 11, in which the PCB board 2 is placed. The lighting fixture also includes a light-transmitting sheet 4, which is fixed in the receiving groove 11 and covers the PCB board 2 and the LED beads 3. The light-transmitting sheet 4 transmits light, and the light emitted by the LED beads 3 passes through the light-transmitting sheet 4 to achieve the lighting effect. It should be noted that the PCB board 2 is a circuit board, and the LED beads 3 are disposed on the PCB board 2, meaning that the LED beads 3 are electrically connected to the circuitry on the PCB board 2. This is prior art known to those skilled in the art, and therefore will not be described in detail here.

[0019] In this embodiment, the PCB board 2 carrying the LED beads 3 is placed in the receiving groove 11, and a light-transmitting sheet 4 is fixed in the receiving groove 11 and covers the PCB board 2 and the LED beads 3. The light emitted by the LED beads 3 passes through the light-transmitting sheet 4 to achieve the lighting effect. The light-transmitting sheet 4 replaces the traditional large and long lampshade, which can effectively reduce the size of the lighting lamp, facilitate installation, and also avoid damage caused by easy bumping.

[0020] Furthermore, by sealing the opening 111 of the receiving groove 11 with the light-transmitting sheet 4, a sealing effect is achieved, reducing the aging effect of air and moisture on the LED beads 3 and improving the service life of the lighting lamp.

[0021] As a further option, see attached Figure 4 As shown, the aforementioned light-transmitting sheet 4 is formed by the curing of adhesive, which covers the PCB board 2 and the LED beads 3. After placing the PCB board 2 in the receiving groove 11, adhesive is injected into the receiving groove 11. The adhesive covers the PCB board 2 and the LED beads 3, which can drive away air and moisture in the receiving groove 11 as much as possible, isolating the LED beads 3 from the air and improving the lifespan of the LED beads 3. At the same time, the adhesive curing into a translucent light-transmitting sheet 4 can scatter the light emitted by the LED beads 3 into diffused light, which has an eye-protecting effect. The adhesive can be a curable adhesive such as epoxy resin.

[0022] In some embodiments, the light-transmitting sheet 4 is made of plastic, such as PC, and is formed into a sheet shape by a mold.

[0023] In some embodiments, as shown in the appendix Figure 3-4 As shown, the bottom surface of the lamp holder 1 has two through holes 12 communicating with the receiving groove 11. The lighting lamp also includes two electrode plates 5, which are placed on the bottom surface of the lamp holder 1. The bottom surface of the lamp holder 1 faces away from the groove opening 111 of the receiving groove 11, and the two electrode plates 5 are respectively fixedly connected to the PCB board 2 by rivets 6. The rivets 6 pass through the through holes 12 so that the two electrode plates 5 are respectively electrically connected to the positive and negative terminals of the LED beads 3. By fixing the electrode plates 5 to the PCB board 2 by the rivets 6, and simultaneously fixing the PCB board 2 in the receiving groove 11, the function of fixing the electrode plates 5 can be achieved, as well as the function of electrically connecting the electrode plates 5 to the positive and negative terminals of the LED beads 3 can be achieved.

[0024] Based on the above embodiments, as shown in the appendix Figure 3 As shown, the bottom surface of the lamp holder 1 is integrally formed with multiple first protrusions 13 arranged in a circle, forming an isolation area 131 between the multiple first protrusions 13. One end of each of the two electrode pieces 5 is placed within the isolation area 131 and connected to the rivet 6, thereby isolating the ends of the two electrode pieces 5 that are electrically connected to the rivet 6. Preferably, glue can be injected into the isolation area 131, covering the part of the two electrode pieces 5 that is electrically connected to the rivet 6, thereby isolating it from air and moisture. Furthermore, a second protrusion 14 is provided between the two electrode pieces 5 to isolate them and prevent short circuits.

[0025] In some embodiments, as shown in the appendix Figure 2-3 As shown, the bottom surface of the lamp holder 1 has several heat dissipation holes 15 that communicate with the receiving groove 11. The heat generated by the PCB board 2 and the LED beads 3 can be discharged through the heat dissipation holes 15. It should be noted that since the bottom surface of the lamp holder 1 is away from the inner cavity of the household appliance, the inner cavity of the household appliance is not connected to the heat dissipation holes 15, and the air and moisture in the inner cavity of the household appliance do not flow to the heat dissipation holes 15.

[0026] Example 2 The household appliance provided in this embodiment includes a lighting lamp as described above. Two electrode plates 5 are electrically connected to the main circuit of the household appliance, and the main circuit controls the power supply of the lighting lamp. It should be noted that this embodiment has little impact on the functional control, structural design, and manufacturing process of the household appliance. It can be widely applied to the existing household appliance product structure and represents an improvement and optimization of the lighting lamp in existing household appliances. It has broad applicability to existing household appliances and can improve the performance and user experience of existing household appliances.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
