Technical Field
[0001] The utility model relates to the technical field of LED light sources, in particular to a heat dissipation shell of an LED bulb. Background Art
[0002] In today's modern lighting landscape, LED bulbs have become extremely popular due to their significant advantages, including superior energy efficiency and long lifespan. With the continuous advancement of technology and the growing demand for lighting, the heat dissipation housings of common LED bulbs are now made of metal materials such as aluminum and copper. Metals have excellent thermal conductivity, allowing them to quickly transfer heat generated by the bulb away.
[0003] However, as the power of LED bulbs gradually increases, the heat generated during operation also increases accordingly. While the heat inside the bulb can be conducted away through metal materials, there is a lack of guidance to direct the conducted heat outward, causing the heat to accumulate inside the bulb and thus unable to be effectively conducted to the heat dissipation area. This can easily lead to local overheating. Since the heat generated by the LED lamp beads during operation cannot be quickly dissipated, heat will accumulate inside the bulb. This not only causes the bulb temperature to rise rapidly, but also makes it difficult to dissipate local heat when it is too high. Excessive temperature will affect the luminous efficiency and color stability of the LED bulb, and will also significantly shorten its service life. In response to the above problems, those skilled in the art have proposed a heat dissipation housing for an LED bulb to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Reference Figure 1 、 Figure 2 and Figure 3 The present invention provides an embodiment of a heat dissipation housing for an LED bulb, comprising a mounting plate 1, which provides a platform for mounting components. A thermally conductive silicone grease plate 2 is fixedly connected to the interior of the mounting plate 1. A heat sink 3 is fixedly connected to the top of the thermally conductive silicone grease plate 2, dissipating heat and improving heat dissipation efficiency. A diverter plate 4 is fixedly connected to the top of the heat sink 3, evenly dissipating heat generated by the LED lamp beads, ensuring more uniform heat dissipation and preventing localized overheating.
[0027] The outside of the diverter plate 4 is fixedly connected with a plurality of connecting blocks 5 to ensure that heat can be transferred to the heat dissipation outer ring 6, further expanding the heat dissipation area. The top of the mounting plate 1 is fixedly connected with a heat dissipation outer ring 6, and the connecting blocks 5 are in contact with the heat dissipation outer ring 6, and can fully exchange heat with the surrounding air. The top of the mounting plate 1 is fixedly connected with a plurality of vertical plates 8, and the tops of the plurality of vertical plates 8 are fixedly connected with the mounting plate 2 9, which plays a supporting and fixing role. The bottom of the mounting plate 1 is fixed with a bulb substrate 18 by bolts. The connection of the bulb substrate 18 is firm, which can ensure the stability of the LED lamp beads during operation. A disassembly component is provided inside the heat dissipation outer ring 6 to facilitate the disassembly and cleaning of the guide plate 7.
[0028] Reference Figure 2 、 Figure 4 and Figure 5 The disassembly component includes a guide plate 7, and the outside of the guide plate 7 is slidably connected to the inside of the heat dissipation outer ring 6, making disassembly and installation more convenient. Two L-shaped plates 11 are fixedly connected to the top of the guide plate 7 to ensure that the guide plate 7 can be accurately installed in place. The outsides of the two L-shaped plates 11 are fixedly connected to the base plate 12, and one side of the base plate 12 is fixedly connected to the plug-in block 13. Two square grooves 10 are respectively provided on the top of the mounting plate 2 9, and the plug-in block 13 is inserted into the inside of the square groove 10. When disassembling, it is only necessary to pull out the plug-in block 13 from the square groove 10. The operation is simple and quick. A plurality of dredging holes 14 are provided on the outside of the guide plate 7. The dredging holes 14 are used for airflow to enter the inside of the heat dissipation outer ring 6, allowing external air to enter the inside of the heat dissipation outer ring 6, thereby promoting air circulation and heat exchange.
[0029] Reference Figure 3 、 Figure 4 and Figure 6 The top of the bulb base plate 18 fits against the bottom of the thermal grease plate 2. The thermal grease plate 2 provides excellent heat conduction, effectively reducing the thermal resistance of the LED bulb. Mounting plate 1 has a threaded ring inside, which is threadedly connected to the lampshade 15. Mounting plate 2 has a threaded ring outside, which is threadedly connected to the upper cover 16. This makes installation and removal of the lampshade 15 and upper cover 16 easier and effectively protects the internal components of the bulb.
[0030] A lamp holder 17 is fixedly attached to the top of the upper cover 16, facilitating connection and installation of the LED lamp beads to an external power source. One side of the riser 8 is fixedly connected to the exterior of the heat dissipation outer ring 6. Multiple LED lamp beads are mounted on the bottom of the bulb base 18. The lampshade 15 is made of acrylic, which facilitates the LED lamp beads to emit light. Acrylic has a certain degree of heat and corrosion resistance, which can protect the internal components of the bulb from external environmental influences.
[0031] Working principle: When the LED lamp bead is working, it generates heat. The heat is first transferred to the bulb substrate 18, then absorbed by the thermal grease plate 2 and transferred to the radiator 3. The heat can be evenly distributed to the heat dissipation outer ring 6 through the diverter plate 4, and then the heat can be effectively dissipated to the surrounding environment. At the same time, the outside air can enter the heat dissipation outer ring 6 through the dredging hole 14, thereby exchanging heat with the heat dissipation outer ring 6, so that the heat can be effectively volatilized outward, thereby accelerating the heat dissipation process.
[0032] Secondly, when the guide plate 7 needs to be disassembled for cleaning, first rotate the upper cover 16 to remove it from the mounting plate 2 9, then rotate the guide plate 7 to the left so that the plug 13 is disengaged from the square groove 10, then extract the guide plate 7 upward so that it slides out from the heat dissipation outer ring 6, and then the debris blocked in the dredging hole 14 can be cleaned out. During installation, first slide the guide plate 7 into the interior of the heat dissipation outer ring 6, then align the L-shaped plate 11 with the square groove 10, so that the bottom plate 12 drives the plug 13 into the interior of the square groove 10, and then rotate the guide plate 7 to the right so that the plug 13 is stuck in the interior of the square groove 10.
[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
