Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, specifically a self-heating lighting structure. Background Technology
[0002] LED lighting fixtures are a type of lighting fixture manufactured around light-emitting diodes (LEDs). They include all components needed to fix and protect the LED light source, in addition to the LED light source itself, as well as the necessary wiring accessories for connecting to the power supply. They have the effect of transmitting light, distributing, and changing the light distribution of the LED light source and are widely used in people's daily lives. However, existing LED lighting fixtures have poor functionality and generally do not have heat dissipation structures. Even if they do have heat dissipation structures, they often blindly pursue heat dissipation area, resulting in complex structures and poor heat dissipation effects. This makes it impossible to conduct the heat of the fixture to the outside of the fixture in a timely manner, thus failing to achieve the heat dissipation function of LED lighting fixtures.
[0003] Based on this, a self-heating lamp structure is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content
[0004] The purpose of this invention is to provide a self-heating lamp structure to solve the problem of poor heat dissipation in LED lamps in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A self-heating lamp structure includes a front cover, a rear cover, and a main lamp body. The main lamp body is disposed between the front cover and the rear cover. The main lamp body includes a housing and a lamp body. The housing is fixedly disposed on the outside of the lamp body. A convection heat dissipation channel is provided between the front cover and the rear cover to promote air circulation by utilizing hot and cold convection. The convection heat dissipation channel is used to absorb the heat generated by the LED lamp beads when they are working by using cold air and to discharge the hot air to the outside environment by the principle of hot air rising.
[0007] Preferably, the convection heat dissipation channel is formed by interconnecting a vent groove, a first heat dissipation groove, a first vent hole, a second heat dissipation groove, and a second vent hole. The vent groove is located in the gap between the front cover and the housing, and is located at the edge of the side wall of the front cover. The extension direction of the vent groove is perpendicular to the edge of the housing. The first heat dissipation groove is located above the vent groove and is formed by the upper surface of the front cover, the inner wall of the housing, and the lower surface of the lamp body. The second heat dissipation groove is located above the first heat dissipation groove and is formed by the inner wall of the housing, the upper surface of the lamp body, and the lower surface of the rear cover. The lamp body has a plurality of first vent holes for connecting the second heat dissipation groove and the first heat dissipation groove. The first vent holes are vertically distributed circumferentially on the lamp body. The second vent holes are evenly distributed on the surface of the rear cover, and there are a plurality of second vent holes.
[0008] Preferably, cold air flows through the bottom of the convection heat dissipation channel. The cold air flows into the first heat dissipation channel through the vent groove between the front cover and the housing, and enters the second heat dissipation channel through several first vent holes. The cold air absorbs heat in the first and second heat dissipation channels and is heated to form hot air. After the hot air dissipates its heat, it rises and is discharged outward through several second vent holes on the rear cover.
[0009] Preferably, a heat sink for improving heat dissipation efficiency is provided between the rear cover and the lamp body. The heat sink is located below the second vent hole, and the outer wall of the heat sink is in contact with the inner wall of the housing.
[0010] Preferably, the lower surface of the lamp body is recessed upward to form a lamp bead position for placing LED lamp beads, and a wire outlet hole for placing power supply cables is provided on one side of the lamp bead position, and the lamp bead position is connected to the wire outlet hole.
[0011] Preferably, a waterproof glass is provided between the lamp body and the front cover, and a waterproof silicone ring is filled in the gap between the waterproof glass and the bottom wall of the lamp body.
[0012] Preferably, the width of the first vent is greater than the width of the second vent.
[0013] Preferably, the two ends of the second vent hole are rounded.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this invention, the heat generated when the LED beads emit light forms high-pressure, high-temperature gas inside the main lamp body. After the heat is dissipated, the hot air rises and is discharged through several second vent holes on the back cover after passing through the heat sink. As the hot air rises, cold air immediately replenishes it and re-enters the gap between the front cover and the main lamp body, i.e., the first heat dissipation groove, through the vent groove. This achieves a circulating exchange of hot and cold air, providing an automatic heat dissipation effect. The heat transfer path is relatively short, and the overall structure is relatively simple, facilitating mass production. In addition, the structure is equipped with waterproof glass and a waterproof silicone ring, effectively preventing moisture from entering the lamp bead area and thus extending the service life of the structure.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] Example 1
[0024] In this embodiment, as Figures 1-5As shown, a self-heating lamp structure includes a front cover 1, a rear cover 2, and a main lamp body 3. The front cover 1 is used to fix the position of the waterproof glass 14. The main lamp body 3 is disposed between the front cover 1 and the rear cover 2. The rear cover 2 has a rear cover fixing screw hole in the middle of its surface. The rear cover 2 is connected to the lamp body 32 by bolts, which facilitates fixing the rear cover 2 to the lamp body 32 and makes maintenance convenient. The front cover 1 has front cover fixing screw holes evenly distributed on it. The front cover 1 is connected to the lamp body 32 by several fastening bolts, which facilitates disassembly and installation and makes maintenance convenient. The main lamp body 3 includes a housing 31 and a lamp body 32. The housing 31 and the lamp body 32 are an integral structure. The housing 31 is fixedly disposed on the outside of the lamp body 32 and serves as a protective layer. The lamp body 32 is used to connect with other components. A convection heat dissipation channel is provided between the front cover 1 and the rear cover 2 to promote air circulation by using hot and cold convection. The convection heat dissipation channel is used to absorb the heat generated by the LED lamp beads when they are working by using cold air, and to exhaust the hot air to the outside environment by the principle of hot air rising. This structure adopts a natural heat dissipation method. No other external measures are taken when the LED lamp beads are working. Its main principle is to transfer the heat generated by the LED lamp beads to the air between the front cover 1 and the rear cover 2, and then, through natural convection, that is, hot air rising and cold air compensation, with the cooperation of the heat dissipation fins 9 which increase the heat dissipation surface area, the heat dissipation is more sufficient and rapid, thereby achieving the purpose of heat dissipation of the LED lamp beads.
[0025] Among them, such as Figures 2-5 As shown, the convection heat dissipation channel is formed by the interconnection of a vent groove 4, a first heat dissipation groove 5, a first vent hole 6, a second heat dissipation groove 7, and a second vent hole 8. The vent groove 4 is located in the gap between the front cover 1 and the housing 31, and is located at the edge of the side wall of the front cover 1. The extension direction of the vent groove 4 is perpendicular to the edge of the housing 31, allowing outside air to enter the main lamp body 3 through the vent groove 4, facilitating the dissipation of heat generated by the LED beads during operation. The first heat dissipation groove 5 is located above the vent groove 4 and is formed by the upper surface of the front cover 1, the inner wall of the housing 31, and the lower surface of the lamp body 32. The second heat dissipation groove... The second heat dissipation groove 7 is located above the first heat dissipation groove 5. The second heat dissipation groove 7 is formed by the inner wall of the housing 31, the upper surface of the lamp body 32, and the lower surface of the rear cover 2. The lamp body 32 is provided with a number of first vent holes 6 for connecting the second heat dissipation groove 7 and the first heat dissipation groove 5. The first vent holes 6 are vertically distributed around the lamp body 32. The radius of the first vent holes 6 is 5mm. The size of the first vent holes 6 is limited so that the number of first vent holes 6 can meet the heat dissipation requirements of the structure. The second vent holes 8 are evenly distributed on the surface of the rear cover 2. There are a number of second vent holes 8 to facilitate the heat dissipation requirements of the LED beads.
[0026] Among them, such as Figures 4-5As shown, cold air flows through the bottom of the convection cooling channel, facilitating air circulation through hot and cold convection. The cold air flows into the first cooling slot 5 through the vent 4 between the front cover 1 and the housing 31, and then enters the second cooling slot 7 through several first vent holes 6. After absorbing heat in the first and second cooling slots 5 and 7, the cold air is heated to form hot air. Once the hot air has dissipated its heat, it rises and is discharged outward through several second vent holes 8 on the rear cover 2. According to the principle of thermodynamics, when air is heated, the movement of gas molecules in it intensifies, causing the gas volume to expand. Due to the conservation of mass, the same volume of hot air is lighter than cold air, that is, the density of hot air decreases, causing the hot air to rise due to the buoyancy of the surrounding cold air. Therefore, when the cold air absorbs the heat generated when the LED beads emit light, the cold air will form high-pressure, high-temperature gas inside the main lamp body 3. After dissipating its heat, the hot air will rise through the convection cooling channel and be discharged through several second vent holes 8. The cold air will then replenish the convection channel through the vent 4, thus repeating the cycle to achieve a self-heating effect.
[0027] Among them, such as Figure 4 and Figure 5 As shown, a heat sink 9 for improving heat dissipation efficiency is provided between the back cover 2 and the lamp body 32. The heat sink 9 is located below the second vent 8. The outer wall of the heat sink 9 is in contact with the inner wall of the housing 31. The heat sink 9 can quickly absorb the heat generated when the LED lamp beads are working and conduct the absorbed heat to various parts of the heat sink 9. It makes full use of the large surface area of the heat sink 9, accelerates the heat dissipation efficiency, and increases the overall practicality of the structure.
[0028] Among them, such as Figure 4 and Figure 5 As shown, the lower surface of the lamp body 32 is recessed upward to form a lamp bead position 10 for placing LED lamp beads. The opening of the lamp bead position 10 faces the front cover 1, so that the light emitted by the LED lamp beads can be diffused through the front cover 1. A wire outlet hole 11 for placing power supply cables is provided on one side of the lamp bead position 10. The lamp bead position 10 is connected to the wire outlet hole 11 for placing cables so that the cables can be connected to power supply equipment. The lamp bead position 10 is connected to the wire outlet hole 11. A waterproof screw hole is provided on one side of the wire outlet hole 11 to play a waterproof role, preventing water from entering the lamp bead position 10 and causing damage to the internal structure, and ensuring that the LED lamp beads can perform light-emitting operation smoothly.
[0029] Example 2
[0030] The difference from Example 1 is that, as in Example 2, ... Figure 4 and Figure 5As shown, a waterproof glass 12 is provided between the lamp body 32 and the front cover 1. The waterproof glass 12 is located below the lamp bead position 10 and serves to waterproof the lamp. A waterproof silicone ring 13 is filled in the gap between the waterproof glass 12 and the bottom wall of the lamp body 32. The waterproof glass 12 and the waterproof silicone ring 13 are in contact to improve the sealing effect inside the lamp bead position 4.
[0031] Among them, such as Figures 2-5 As shown, the width of the first vent 6 is greater than the width of the second vent 8, which facilitates air circulation and plays a role in rapid heat dissipation.
[0032] Among them, such as Figure 2 As shown, the two ends of the second vent 8 are rounded to reduce stress concentration and prevent the second vent 8 from cracking.
[0033] Working principle: When this structure is working, the LED beads will generate heat in the gap between the LED bead position 10, the lamp body 32, and the heat sink 9. Under the action of the front cover 1 and the rear cover 2, the hot air will form a high pressure and high temperature inside the main lamp body 3, so the entire airflow will be discharged along the second vent hole 8 of the rear cover 2. Then, the cold air enters the gap between the heat sink 9 and the LED bead position 10, i.e., the second heat dissipation groove 7, through the first vent hole 6 from the reserved vent groove 4 between the front cover 1 and the housing 31. At this time, it will be heated and form hot air again, and then be discharged again. The above steps are repeated. In this way, the cold air circulates and detours, which can remove the heat generated by the LED beads when they are working, so as to achieve the heat dissipation effect.
[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
