Description

Technical Field

[0001] This utility model relates to the field of corn lamp technology, and more specifically, to a corn lamp with high heat dissipation. Background Technology

[0002] LED corn lights are widely used in industrial plants, road lighting, and other places due to their high luminous efficiency and energy-saving effect. For example, patent publication number CN216243644U describes a long-life LED corn light, which relates to the field of LED corn light technology. It includes a corn light body and a mounting frame. LED beads are installed on the outer surface of the corn light body, and heat dissipation grooves are opened on the outer surface of the corn light body. A protective cover is fixed on the outer surface of the mounting frame. Insect-proof components are provided on the outer surfaces of the corn light body and the protective cover. It also includes a mounting block, which is fixed on the top of the corn light body. The insect-proof components include an insect-proof net, a plug ring, and a ring-cut groove.

[0003] However, the aforementioned corn lamps, due to the influence of the protective cover or lampshade, will cause heat to accumulate inside the corn lamp. In order to achieve the desired effect, it is necessary to use the protective cover or lampshade, which will significantly increase the heat generated by the LED during operation. If it cannot be dissipated in a timely and effective manner, it will directly lead to the increase of the internal temperature of the lamp body, resulting in problems such as shortened lifespan. Therefore, we have made improvements to this issue and proposed a corn lamp with high heat dissipation performance, which provides heat dissipation treatment for the LED light sheet located inside the outer shell and lampshade. Utility Model Content

[0004] The main purpose of this invention is to provide a corn lamp with high heat dissipation, which can effectively solve the problem that existing corn lamps are prone to heat accumulation, which affects the performance of the internal LEDs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high heat dissipation corn lamp includes a housing, a lamp holder fixedly installed at the upper end of the housing, a lamp cover threaded on the outer side of the lower end of the housing, a heat dissipation component for guiding heat dissipation inside the housing, the heat dissipation component including a thermally conductive support cylinder disposed inside the housing, a flexible LED light sheet attached to the outer side of the thermally conductive support cylinder, and a thermally conductive ring integrally disposed at the upper end of the thermally conductive support cylinder.

[0006] Preferably, the inner wall of the thermally conductive support cylinder is provided with connecting threads, the inside of the housing is provided with a connecting seat, and the outer surface of the connecting seat is provided with mating threads, the mating threads being threadedly engaged with the connecting threads.

[0007] Preferably, an exchange cavity is provided on the inner side of the lower end of the housing, and a plurality of ventilation holes are provided on the outer side of the exchange cavity.

[0008] Preferably, the heat-conducting ring is located inside the exchange cavity, and a plurality of fins are integrally formed on the upper surface of the heat-conducting ring, with the plurality of fins being horizontally aligned with a plurality of air exchange holes.

[0009] Preferably, the heat-conducting support cylinder is provided with an extension frame inside, and the extension frame is provided with a drive plate inside. The drive plate is electrically connected to the lamp holder via a connecting cable, and the drive plate is located between the extension frame and the lamp holder.

[0010] Preferably, the output end of the driver board is electrically connected to the flexible LED light sheet via another set of connecting cables.

[0011] Preferably, the flexible LED light sheet has a support ring at its bottom, and a plurality of support rods are provided on the upper side of the support ring, with the plurality of support rods being staggered with the LED light sheet core.

[0012] Preferably, the bottom of the heat-conducting ring is provided with several combined slots, and the upper ends of several support rods are respectively inserted and connected to adjacent combined slots.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) By using a high thermal conductivity material for the thermally conductive support cylinder, the heat generated by the flexible LED sheet surrounding the outer side of the thermally conductive support cylinder during use can be conducted upwards by the thermally conductive support cylinder. Compared with the existing corn lamps that do not have a heat dissipation structure and cause heat to accumulate in the lamp cover and housing, this application can guide the heat generated inside the lamp cover and housing, and with the help of the thermally conductive ring, make it contact with the outside air to achieve heat exchange, thereby achieving a high heat dissipation effect, thus improving the service life of the corn lamp of this application and making it more suitable for long-term lighting needs. In addition, the thermally conductive support cylinder can also support the flexible LED sheet, so that the flexible LED sheet can meet the lamp core position setting around the outer perimeter and bottom after being attached, reducing the use of support components and integrating the heat dissipation structure and the support structure.

[0014] (2) It should be noted that both the heat-conducting ring and the heat-conducting support cylinder are made of high thermal conductivity materials. The heat-conducting ring and several fins are integrated into one piece, and the heat-conducting ring and the heat-conducting support cylinder are also integrated into one piece. This allows the heat to be continuously transferred to the heat-conducting ring when the heat-conducting support cylinder receives heat, and the heat exchange efficiency of the heat-conducting ring is enhanced by several fins, thereby meeting the requirements of high heat dissipation performance.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1 to 10 As shown, a high heat dissipation corn lamp includes a housing 1. A power supply lamp head 101 is fixedly installed on the upper end of the housing 1. A lamp cover 102 is threaded on the outer side of the lower end of the housing 1. A heat dissipation component 2 for guiding heat dissipation is provided inside the housing 1. The heat dissipation component 2 includes a heat-conducting support cylinder 201, which is disposed inside the housing 1. A flexible LED lamp sheet 4 is attached to the outer side of the heat-conducting support cylinder 201. A heat-conducting ring 203 is integrally provided on the upper end of the heat-conducting support cylinder 201.

[0019] By using a highly thermally conductive material in the heat-conducting support cylinder 201, the heat generated by the flexible LED light sheet 4 surrounding the outer side of the heat-conducting support cylinder 201 during use can be conducted upwards by the heat-conducting support cylinder 201. Compared with existing corn lamps that lack a heat dissipation structure and cause heat to accumulate in the lamp cover 102 and housing 1, this application can guide the heat generated inside the lamp cover 102 and housing 1, and in conjunction with the heat-conducting ring 203, allow it to contact the outside air to exchange heat, achieving a high heat dissipation effect. This extends the lifespan of the corn lamp and is more suitable for long-term lighting needs. Furthermore, the heat-conducting support cylinder 201 also supports the flexible LED light sheet 4, allowing the LED light sheet 4 to meet the lamp core position settings around the outer perimeter and bottom after bonding, reducing the use of support components and integrating the heat dissipation structure and support structure.

[0020] In this embodiment, the inner wall of the heat-conducting support cylinder 201 is provided with a connecting thread 207, and the housing 1 is provided with a connecting seat 7. The outer surface of the connecting seat 7 is provided with a mating thread 8, which is threadedly engaged with the connecting thread 207. During disassembly and assembly, the heat-conducting support cylinder 201 can be disassembled and assembled by rotating the housing 1 through the threaded engagement of the mating thread 8 and the connecting thread 207, which is beneficial for the subsequent wiring and positioning of the drive board 3.

[0021] In this embodiment, an exchange cavity 205 is provided on the inner side of the lower end of the housing 1, and a plurality of ventilation holes 206 are provided on the outer side of the exchange cavity 205. A heat-conducting ring 203 is located inside the exchange cavity 205, and a plurality of fins 204 are integrally provided on the upper surface of the heat-conducting ring 203. The plurality of fins 204 are horizontally aligned with the plurality of ventilation holes 206.

[0022] The heat exchange cavity 205 has several ventilation holes 206 on its outer side. The heat can be concentrated in several fins 204 by the heat exchange cavity 205. The fins 204 increase the heat exchange area, and the ventilation holes 206 allow outside air to be introduced, thereby further improving the heat dissipation effect of the heat-conducting support cylinder 201 and the heat-conducting ring 203.

[0023] In this embodiment, an extension frame 202 is provided inside the heat-conducting support cylinder 201, and a drive plate 3 is provided inside the extension frame 202. The input end of the drive plate 3 is electrically connected to the power supply lamp head 101 through a connecting cable 6. The drive plate 3 is located between the extension frame 202 and the power supply lamp head 101. The output end of the drive plate 3 is electrically connected to the flexible LED light sheet 4 through another set of connecting cables 6.

[0024] By connecting the power supply lamp head 101 to an external lamp holder, power can be sequentially transmitted to the power supply lamp head 101, the driver board 3, and the flexible LED light sheet 4, thereby fulfilling the overall lighting requirements of the flexible LED light sheet 4.

[0025] In this embodiment, a support ring 501 is provided at the bottom of the flexible LED light sheet 4, and a plurality of support rods 5 are provided on the upper side of the support ring 501. The plurality of support rods 5 are staggered with the LED core of the flexible LED light sheet 4. A plurality of combined slots 208 are opened at the bottom of the heat-conducting ring 203, and the upper ends of the plurality of support rods 5 are respectively inserted and connected to adjacent combined slots 208. The support ring 501 and the plurality of support rods 5 can cooperate with the combined slots 208 to fix the position of the flexible LED light sheet 4 on the outside of the heat-conducting support cylinder 201 to ensure the stability of heat dissipation of the flexible LED light sheet 4. Furthermore, the support ring 501 and the plurality of support rods 5 can be made of high thermal conductivity materials. By using the support ring 501, the plurality of support rods 5 and the flexible LED light sheet 4 to fit together, heat can be guided to the outer part of the flexible LED light sheet 4, thereby improving the heat dissipation effect.

[0026] It should be noted that both the heat-conducting ring 203 and the heat-conducting support cylinder 201 are made of high thermal conductivity materials. The heat-conducting ring 203 is integrally set with several fins 204, and the heat-conducting ring 203 and the heat-conducting support cylinder 201 are also integrally set. This allows the heat to be continuously transferred to the heat-conducting ring 203 when the heat-conducting support cylinder 201 receives heat. The heat exchange efficiency of the heat-conducting ring 203 is enhanced by the several fins 204, thereby meeting the requirements of high heat dissipation performance. By guiding the accumulated heat out for heat dissipation, the seal between the flexible LED light sheet 4 and the housing 1 and the lamp cover 102 is not affected. In addition, dustproof nets can be set on the outside of several ventilation holes 206 in dusty environments to ensure heat dissipation effect.

[0027] The working principle of this high heat dissipation corn lamp: In use, the lamp head 101 is connected to an external lamp holder, allowing power to be sequentially transmitted to the lamp head 101, the driver board 3, and the flexible LED sheet 4, enabling the flexible LED sheet 4 to perform lighting operations. During the lighting process, the flexible LED sheet 4 generates heat. When heat is generated, the heat is transferred to several fins 204 through the heat-conducting ring 203 and the heat-conducting support cylinder 201, both of which are made of highly thermally conductive materials. The heat is concentrated by the heat exchange cavity 205, and several ventilation holes 206 allow outside air to be introduced, achieving a heat dissipation effect.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
