Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an integrated LED heat dissipation lamp structure. Background Technology

[0002] Against the backdrop of global advocacy for energy conservation, emission reduction, and green development, LED lighting technology has rapidly gained dominance in the lighting market due to its significant energy-saving advantages. Compared to traditional incandescent bulbs, LED lamps can save up to 80% of electricity, and their extended lifespan significantly reduces replacement frequency and maintenance costs, leading to their widespread application in numerous fields such as commercial and residential lighting.

[0003] However, in the current technology, most mainstream LED lighting fixtures adopt an assembly method where the heat sink is independently assembled with the main body of the fixture. This split structure has many drawbacks: First, the connection between the heat sink and the main body of the fixture often requires additional fasteners and sealing materials, which not only increases the number of parts and assembly steps, but also prolongs the production cycle and increases production costs; Second, the contact interface between the heat sink and the main body of the fixture in the split structure is prone to thermal resistance, which leads to a reduction in heat conduction efficiency and affects the overall heat dissipation effect; Third, the independent heat sink is relatively large, which increases the space occupied by the fixture and is not conducive to the application of the fixture in some space-constrained scenarios. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose an integrated LED heat dissipation lamp structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated LED heat dissipation lamp structure, comprising a lamp cup, a lamp plate, and a heat sink, wherein a plurality of ventilation holes are provided through one end of the lamp cup, a circular ring bracket is fixedly installed on the inner wall of the lamp cup, and a detachable ventilation mesh is installed on the other end of the lamp cup, and a circular ring bracket is installed on the outer wall of the heat sink, wherein a plurality of elliptical holes are provided through one end of the circular ring bracket.

[0006] Preferably, the lamp plate is installed inside the lamp cup and near the opening, and the heat sink is located inside the lamp cup.

[0007] Preferably, the lower end of the circular bracket is fixed to one end of the circular bracket plate, and one end of the heat sink is in contact with one end of the lamp plate.

[0008] Preferably, one end of the lamp cup is fitted with a detachable lampshade, and the other end of the lamp cup is fitted with a detachable protective shell.

[0010] Preferably, a mounting bracket is fixedly installed on the outer wall of the lamp cup, and a copper head is installed through the outer wall of the lamp cup.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by installing a circular bracket on the outer wall of the heat sink, the heat sink can be positioned in the middle, and multiple sets of ventilation holes can be passed through one end of the lamp cup.

[0012] 2. In this utility model, by adopting an integrated design, the heat sink, lamp plate, circular frame plate, and circular bracket are integrated into the lamp cup, which reduces the connection and assembly process between parts, reduces production costs, and improves production efficiency.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-4 As shown, this utility model provides an integrated LED heat dissipation lamp structure, including a lamp cup 1, a lamp plate 8, and a heat sink 9. One end of the lamp cup 1 has multiple sets of ventilation holes 6. A circular ring bracket plate 10 is fixedly installed on the inner wall of the lamp cup 1. A detachable ventilation mesh plate 11 is installed on the other end of the lamp cup 1. A circular ring bracket 12 is installed on the outer wall of the heat sink 9. One end of the circular ring bracket plate 10 has multiple sets of elliptical holes 13. The lamp plate 8 is installed inside the lamp cup 1 and near the opening. The heat sink 9 is located inside the lamp cup 1. The lower end of the circular ring bracket 12 is fixed to one end of the circular ring bracket plate 10. One end of the heat sink 9 is in contact with one end of the lamp plate 8.

[0018] The specific settings and functions of this embodiment are described in detail below. A lamp plate 8 is installed inside the lamp cup 1 at the displacement opening. A circular frame plate 10 is installed on the inner wall of the lamp plate 8. A heat sink 9 is tightly attached to one end of the lamp plate 8. At the same time, a circular bracket 12 is installed on the outer wall of the heat sink 9, and the lower end of the circular bracket 12 is fixed to one end of the circular frame plate 10, so that the heat sink 9 is hollow, which facilitates its heat dissipation. Multiple sets of ventilation holes 6 are opened through one end of the lamp cup 1, and a detachable ventilation mesh plate 11 is installed on the other end of the lamp cup 1. Multiple sets of elliptical holes 13 are opened through one end of the circular frame plate 10, so that an air convection channel is formed inside the lamp cup 1, thereby quickly dissipating the heat generated by the LED chip on the lamp plate 8, effectively reducing the temperature of the LED chip on the lamp plate 8, and improving the luminous efficiency and service life of the lamp. The radiator 9 is made of aluminum alloy die casting in one piece. The surface is anodized to improve heat dissipation efficiency. Radial heat dissipation fins are set inside the radiator 9. The contact surface between the radiator 9 and the lamp board 8 is processed with microgrooves to reduce contact thermal resistance.

[0019] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, a detachable lampshade 4 is installed at one end of the lamp cup 1, a detachable protective shell 5 is installed at one end of the lamp cup 1, a detachable annular sealing mesh 7 is installed at one end of the lamp cup 1 and at one end of the multiple sets of ventilation holes 6, a part of the lampshade 4 is located inside the protective shell 5 and the annular sealing mesh 7, a mounting bracket plate 2 is fixedly installed on the outer wall of the lamp cup 1, and a copper head 3 is installed through the outer wall of the lamp cup 1.

[0020] The overall effect of this embodiment is that a detachable annular sealing mesh 7 is installed at one end of the lamp cup 1 with multiple sets of ventilation holes 6 at the bottom. The annular sealing mesh 7 adopts a magnetic or snap-on quick-installation structure, which allows users to easily disassemble and install it according to their usage needs. The mesh body is made of 304 stainless steel woven mesh, and the mesh diameter is precisely controlled between 0.3 and 0.5 mm. This effectively blocks dust particles, flying insects and other foreign objects from entering the lamp cup 1, preventing them from adhering to the surface of the lamp plate 8 and the heat sink 9 and affecting heat dissipation and circuit performance. At the same time, it does not significantly obstruct the ventilation efficiency of the ventilation holes 6, ensuring that air can pass through smoothly and maintaining good air circulation inside the lamp, achieving a balance between protection and heat dissipation. In addition, the inner edge of the annular sealing mesh 7 is provided with an elastic silicone sealing ring, which can fit tightly against the inner wall of the lamp cup 1 after installation, further improving the sealing effect. A detachable lampshade 4 is installed at the top opening of the lamp cup 1. The lampshade 4 and the lamp cup 1 are connected by a threaded screw or snap-fit ​​connection, which facilitates the cleaning, inspection and other maintenance operations of the lamp fixture in the future. The lampshade 4 is made of polycarbonate (PC) material with a light transmittance of more than 92% and is injection molded. The surface is hardened and has good scratch and wear resistance. The edge of the lampshade 4 is provided with a groove, and a waterproof rubber strip is embedded in the groove. When the lampshade 4 is installed on the lamp cup 1, the waterproof rubber strip is pressed and a sealing structure is formed, which can effectively prevent dust, water vapor and other substances from entering the interior of the lamp cup 1 and avoid them from adhering to the lamp plate 8 and lens, affecting the lighting effect and circuit safety. At the same time, it does not affect the normal transmission of the light emitted by the lamp fixture and ensures the lighting quality. A mounting plate 2 is fixedly installed on the outer wall of the lamp cup 1 to facilitate the assembly of the lamp cup 1. A copper head 3 is installed through the outer wall of the lamp cup 1 and is electrically connected to the lamp board 8. The copper head 3 is used to connect to an external power source.

[0021] The usage method and working principle of this device are as follows: First, when the lamp is powered on, the LED chip on the lamp board 8 generates a lot of heat. This heat is first transferred to the lamp board 8 through thermal conduction. Since the lamp board 8 is made of aluminum substrate, its good thermal conductivity allows the heat to be quickly conducted to the heat sink 9 which is in close contact with the lamp board 8. The integrated heat sink on the radiator 9 increases the heat dissipation area, providing a larger contact surface for heat dissipation. At this time, natural wind or artificial airflow enters the vent 6 through the protective shell 5 and flows through the gaps in the heat sink on the surface of the radiator 9. During this process, the air comes into full contact with the heat sink, carrying away the heat on the heat sink. The heat is dissipated to the surrounding environment through thermal convection and flows out through multiple sets of elliptical holes 13 and the vent mesh plate 11. At the same time, the opening at the top of the lamp cup 1 is connected to the outside, forming an air circulation channel, allowing fresh air to continuously enter the interior of the lamp cup 1, continuously carrying away heat and ensuring that the heat inside the lamp can be dissipated in time, maintaining the LED chip on the lamp board 8 within a suitable operating temperature range.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
