Description

Technical Field

[0001] This utility model relates to the field of light source module technology, and in particular to a light-emitting diode module. Background Technology

[0002] With the continuous maturation of LED lighting technology, LEDs are increasingly entering the market and being accepted by consumers, showing a strong trend of replacing traditional lighting fixtures. LED lights are a type of semiconductor diode that converts electrical energy into light energy. Like ordinary diodes, LEDs consist of a PN junction and also exhibit unidirectional conductivity.

[0003] Light-emitting diodes (LEDs) typically emit light of specific wavelengths, such as visible light. However, most of the energy received by an LED is converted into heat, with only the remainder being converted into light energy. Therefore, the heat generated by an LED must be dissipated to ensure its proper operation.

[0004] Currently, LED chips are fixed on printed circuit boards. To ensure the light-emitting effect, LED chips use a conical reflector. This results in a gap between the reflector and the outer casing, which leads to slow heat transfer efficiency and poor heat dissipation. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a light-emitting diode module with simple structure, good heat dissipation effect and convenient use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A light-emitting diode module includes a base, a heat sink, a reflector, a printed circuit board mounted inside the reflector, a light-emitting diode chip mounted on the printed circuit board, a light-transmitting cover, and a retaining ring;

[0008] The base is cylindrical, and the heat sink includes a heat sink plate and a heat sink cover fixedly installed at the lower end of the heat sink plate. The heat sink is fixedly connected to the base, and the heat sink cover is disposed inside the base. The reflector is disposed inside the base, and the upper end of the reflector has a wire hole. The mounting plate has a through hole, and the outer side of the reflector fits against the inner side of the heat sink cover. The lower end of the base is provided with an external thread, and the inner side of the pressure ring is provided with an internal thread for threaded connection with the base. The lower end of the pressure ring protrudes inward to provide a limiting platform, and the light-transmitting cover is located between the base and the limiting platform.

[0009] In this assembly process, the heat sink is fixedly connected to the base, the heat sink cover is located inside the base, the reflector is placed inside the heat sink cover, and the reflector and heat sink cover are fitted together. Then, the light-transmitting cover is placed below the base, and the light-transmitting cover is pressed tightly using a pressure ring to complete the assembly. The printed circuit board has outward-facing wires, which are routed outwards through vias and holes for easy connection. During use, the printed circuit board and LED chip generate heat, which is transferred to the reflector. The heat sink cover allows for rapid heat transfer from the reflector to the heat sink cover itself, and then to the heat sink plate for rapid outward dissipation. Simultaneously, heat is also dissipated outwards through the base.

[0010] Preferably, the inner side of the heat sink has a plurality of radially arranged inner ribs, and the outer side of the reflector is recessed to form a slot for insertion and engagement with the inner ribs.

[0011] Preferably, the outer side of the heat sink is provided with a plurality of radially arranged protruding ribs, and the base is provided with a slot for engaging with the protruding ribs. The protruding ribs pass through the slots and extend outward, and the upper end of the protruding ribs is fixedly connected to the heat sink plate.

[0012] Preferably, two supports are fixedly installed on the inner side of the base, each support having a threaded hole, and the heat sink having a through hole opposite the threaded hole. The heat sink and the supports are fixedly connected by screws.

[0013] Preferably, the heat sink, the outer rib, the heat sink cover, and the inner rib are all made of aluminum.

[0014] In summary, this LED module has the advantages of simple structure, good heat dissipation, and ease of use. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0019] like Figure 1-3 As shown, a light-emitting diode module includes a base 1, a heat sink 2, a reflector 3, a printed circuit board 4 mounted inside the reflector, a light-emitting diode chip 5 mounted on the printed circuit board, a light-transmitting cover 6, and a retaining ring 7.

[0020] The base is cylindrical, and the heat sink includes a heat sink plate 8 and a heat sink cover 9 fixedly installed at the lower end of the heat sink plate. The heat sink is fixedly connected to the base and the heat sink cover is disposed inside the base. The reflector is disposed inside the base. The upper end of the reflector has a wire hole. The mounting plate has a through hole. The outer side of the reflector fits against the inner side of the heat sink cover. The lower end of the base is provided with an external thread 10. The inner side of the pressure ring is provided with an internal thread 11 for threaded connection with the base. The lower end of the pressure ring protrudes inward and is provided with a limiting platform 12. The light-transmitting cover is located between the base and the limiting platform.

[0021] In this assembly process, the heat sink is fixedly connected to the base, the heat sink cover is located inside the base, the reflector is placed inside the heat sink cover, and the reflector and heat sink cover are fitted together. Then, the light-transmitting cover is placed below the base, and the light-transmitting cover is pressed tightly using a pressure ring to complete the assembly. The printed circuit board has outward-facing wires, which are routed outwards through vias and holes for easy connection. During use, the printed circuit board and LED chip generate heat, which is transferred to the reflector. The heat sink cover allows for rapid heat transfer from the reflector to the heat sink cover itself, and then to the heat sink plate for rapid outward dissipation. Simultaneously, heat is also dissipated outwards through the base.

[0022] Without a heat sink, heat can only pass through the reflector and then be dissipated through the air between the reflector and the base, finally dissipating outward through the base. However, with a heat sink installed, heat is transferred to the heat sink, and then to the heat sink plate and the cylinder. Compared to air transmission, this can accelerate the heat dissipation efficiency.

[0023] In implementation, the inner side of the heat sink has several radially arranged protruding ribs 13, and the outer side of the reflector has recessed slots 14 for engaging with the protruding ribs. The protruding ribs and slots further increase the contact area between the heat sink and the reflector, accelerating heat transfer and achieving rapid heat dissipation.

[0024] In implementation, the outer side of the heat sink shroud is provided with several radially arranged protruding ribs 15. The base has slots 16 for engaging with these ribs. The ribs extend outward through the slots, and their upper ends are fixedly connected to the heat sink plate. By ensuring the ribs fit snugly against the sidewalls of the slots, heat from the heat sink shroud can be quickly transferred to the base and dissipated outwards, accelerating heat dissipation.

[0025] In implementation, two supports 17 are fixedly installed on the inner side of the base. Each support has a threaded hole, and the heat sink has a through hole opposite the threaded hole. The heat sink and the supports are fixedly connected by screws. The supports facilitate the connection between the base and the heat sink.

[0026] In practice, the heat sink plate, outer ribs, heat sink cover, and inner ribs are all made of aluminum. Aluminum provides excellent heat dissipation. Furthermore, the heat sink base is integrally molded, facilitating manufacturing.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
