Description
Technical Field
[0001] This application relates to the field of lighting technology, and in particular to a heat-conducting work lamp. Background Technology
[0002] As a type of lighting fixture that combines practicality and decoration, work lights need to be kept on for extended periods to ensure continuous illumination for work. However, prolonged use of work lights generates a significant amount of heat, which not only affects their lifespan but also makes them prone to damage, inevitably impacting the continuous illumination required for work. Existing solutions typically involve installing work lights in well-ventilated or low-temperature locations to provide heat dissipation. However, this method accelerates the dissipation of external heat while failing to effectively remove internal heat. Summary of the Invention
[0003] To address the aforementioned problems, this application provides a heat-conducting work lamp.
[0004] The heat-conducting work lamp provided in this application adopts the following technical solution: A heat-conducting work lamp includes a lamp holder, a lamp plate, a lens, a face mask, and a heat-conducting rear shell. The lamp holder is installed on the inner wall of the heat-conducting rear shell, and the heat-conducting rear shell encloses the lamp holder to form a concave structure. The lamp holder is connected to an outwardly extending power cord. The lamp plate is located inside the heat-conducting rear shell and is installed on the lamp holder. The lamp plate is connected to the power cord to provide illumination. When heat is generated, it is transferred to the outside through the heat-conducting rear shell. The lens is snapped into the heat-conducting rear shell, and the face mask covers the lens.
[0005] By adopting the above technical solution, when the heat-conducting back shell is covered by the lens and mask, a sealed environment is formed inside the heat-conducting back shell to prevent dust or moisture from entering. The lamp holder and power cord provide the installation and power connection for the lamp board, enabling the lamp board to produce light for illumination. During the illumination process, the heat generated is transferred to the outside through the heat-conducting back shell and heat exchanged with the outside air to dissipate heat, thereby improving the heat dissipation efficiency.
[0006] Optionally, the heat-conducting back shell includes an inner heat-conducting frame, an outer heat-conducting frame, a middle plastic frame, and connecting heat-conducting pillars; the lamp holder is mounted on the middle plastic frame, and the middle plastic frame has a plurality of heat-conducting holes; a plurality of connecting heat-conducting pillars are provided, corresponding one-to-one with the heat-conducting holes, and are inserted into the heat-conducting holes, and the length of the connecting heat-conducting pillars is longer than the depth of the heat-conducting holes; the inner heat-conducting frame is located inside the middle plastic frame and is connected to the end of the connecting heat-conducting pillars near the inside of the middle plastic frame; the outer heat-conducting frame is located outside the middle plastic frame and is connected to the end of the connecting heat-conducting pillars outside the middle plastic frame.
[0007] By adopting the above technical solution, when the lamp panel generates heat, the heat is absorbed by the inner heat-conducting frame and transferred to the outer heat-conducting frame through the connecting heat-conducting column. The outer heat-conducting frame is located on the outside, so it directly exchanges heat with the outside air, thereby accelerating the heat dissipation speed of the outer heat-conducting frame. After the outer heat-conducting frame cools down, it continues to transfer the heat of the inner heat-conducting frame through the connecting heat-conducting column, so as to achieve the effect of cooling and absorbing heat around the lamp panel and extending the service life of the overall work lamp.
[0008] Optionally, the inner heat-conducting frame is installed close to the middle plastic frame, so that the connecting heat-conducting column extends outward from the heat-conducting hole with the inner heat-conducting frame as the base point, and a gap is formed between the outer heat-conducting frame and the middle plastic frame.
[0009] By adopting the above technical solution, the inner heat-conducting frame is installed close to the inner wall of the middle plastic frame, which allows the heat-conducting holes to be closed by the inner heat-conducting frame, further preventing dust or moisture from entering the middle heat-conducting frame. An intervening space is formed between the outer heat-conducting frame and the middle plastic frame, which increases the heat dissipation area of the outer heat-conducting frame and improves the heat dissipation efficiency.
[0010] Optionally, the surface of the inner heat-conducting frame is polished to form a reflective surface.
[0011] By adopting the above technical solution, when the light panel shines on the inner heat-conducting frame, the reflective surface formed after polishing can be used to reflect the light towards the lens and mask, thereby achieving the effect of partial light focusing and reflection.
[0012] Optionally, the outer wall of the middle plastic frame is further provided with a heat insulation shell, and the heat insulation shell covers the outer heat-conducting frame.
[0013] By adopting the above technical solution, the heat insulation shell is used to block the outer heat-conducting frame, so that when maintenance workers or cleaning personnel come into contact with the work light, they directly contact the heat insulation shell instead of the outer heat-conducting frame, thereby achieving the protection against burns and leakage, and improving the safety of the work light.
[0014] Optionally, the outer heat-conducting frame has several connecting ports, and the heat insulation shell has heat insulation columns corresponding to each of the connecting ports. The heat insulation shell passes through the connecting ports through the heat insulation columns and is connected to the outer wall of the middle plastic frame.
[0015] By adopting the above technical solution, the heat insulation shell can be connected to the outer wall of the middle plastic frame through the heat insulation column through the connecting port. At the same time, the heat insulation shell is not connected to the outer heat-conducting frame, so that the heat dissipation of the outer heat-conducting frame will not be affected. The heat insulation shell can also prevent maintenance personnel or cleaning personnel from touching the outer heat-conducting frame, so as to ensure heat dissipation and provide a safe use effect.
[0016] Optionally, the diameter of the insulation column is smaller than the inner diameter of the connecting opening.
[0017] By adopting the above technical solution, the heat insulation column passes through the middle of the connection port, so that the heat insulation column will not touch the outer heat conduction frame and will not affect the heat dissipation of the outer heat conduction frame. At the same time, opening several connection ports can also provide gas circulation and accelerate the heat dissipation efficiency of the outer heat insulation frame.
[0018] Optionally, there is a space between the heat insulation shell and the outer heat-conducting frame.
[0019] By adopting the above technical solution, the space between the heat insulation shell and the outer heat-conducting frame allows air or airflow to pass through the space, so that the heat insulation shell can cover the heat-conducting frame without affecting the heat dissipation efficiency of the outer heat-conducting frame.
[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When the heat-conducting back shell is covered by the lens and mask, a sealed environment is formed inside the heat-conducting back shell to prevent dust or moisture from entering. The lamp holder and power cord provide the installation and power connection of the lamp board, enabling the lamp board to produce light for illumination. During the illumination process, the heat generated is transferred to the outside through the heat-conducting back shell and heat exchanged with the outside air to dissipate heat, thereby improving the heat dissipation efficiency. 2. When the lamp panel generates heat, the heat is absorbed by the inner heat-conducting frame and transferred to the outer heat-conducting frame through the connecting heat-conducting columns. The outer heat-conducting frame is located on the outside, so it directly exchanges heat with the outside air, thereby accelerating the heat dissipation speed of the outer heat-conducting frame. After the outer heat-conducting frame cools down, it continues to transfer the heat of the inner heat-conducting frame through the connecting heat-conducting columns, so as to achieve the effect of cooling and absorbing heat around the lamp panel and extending the service life of the overall work lamp. 3. The inner heat-conducting frame is installed close to the inner wall of the middle plastic frame, so that the heat-conducting holes can be closed by the inner heat-conducting frame, further preventing dust or moisture from entering the middle heat-conducting frame. An interval space is formed between the outer heat-conducting frame and the middle plastic frame, which increases the heat dissipation area of the outer heat-conducting frame and improves the heat dissipation efficiency. 4. The inner heat-conducting frame is installed close to the inner wall of the middle plastic frame, which allows the heat-conducting holes to be closed by the inner heat-conducting frame, further preventing dust or moisture from entering the middle heat-conducting frame. An interlayer space is formed between the outer heat-conducting frame and the middle plastic frame, which increases the heat dissipation area of the outer heat-conducting frame and improves heat dissipation efficiency.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.
[0028] This application discloses a heat-conducting work lamp.
[0029] A heat-conducting work lamp, reference Figure 1 and Figure 2 As shown, it includes a lamp holder 1, a lamp plate 2, a lens 3, a faceplate 4, and a heat-conducting rear shell 5. The lamp holder 1 is installed on the inner wall of the heat-conducting rear shell 5. The lamp holder 1 serves as the main mounting structure for the work light. The heat-conducting rear shell 5 provides mounting for the lamp holder 1 in a wrapped manner to form a concave structure. The heat-conducting rear shell 5 provides heat dissipation. The lamp holder 1 is connected to an outwardly extending power cord 11, which provides power supply so that the work light can be lit.
[0030] The lamp board 2 is located inside the heat-conducting back cover 5 and is mounted on the lamp holder 1. The mounting method can be bolt fastening. As the main component providing the light source, the lamp board 2 can be an LED lamp board 2. When mounted on the lamp holder 1, it is connected to the power cord 11. The power cord 11 provides power to the lamp board 2. When the lamp board 2 is turned on for illumination, the lamp board 2 generates heat. The heat is transferred to the outside through the heat-conducting back cover 5 for heat dissipation. The lens 3 is snapped into the heat-conducting back cover, covering the back opening of the heat-conducting back cover 5. The lens 3 is made of transparent plastic and does not affect the light transmission. The mask 4 covers the lens 3 so that the illumination light is not blocked. The mask 4 can be made of semi-transparent frosted material to disperse the light and reduce direct light irradiation. When the lens 3 and the mask 4 cover the back opening of the heat-conducting back cover 5, the concave structure inside the heat-conducting back cover forms a sealed or closed state, so that dust or moisture will not affect the operation of the lamp board 2.
[0031] Specifically, when the heat-conducting back shell 5 is covered by the lens 3 and the mask 4, a sealed environment is formed inside the heat-conducting back shell 5 to prevent dust or moisture from entering. The lamp holder 1 and the power cord 11 provide the installation and power connection for the lamp board 2, enabling the lamp board 2 to produce light for illumination. During the illumination process, the heat generated is transferred through the heat-conducting back shell 5 to the outside, where it exchanges heat with the outside air to dissipate heat, thereby improving the heat dissipation efficiency.
[0032] The bottom of the heat-conducting rear shell 5 can also be provided with a hinge seat 6, which can be used to easily adjust the overall illumination angle of the work light.
[0033] Further reference Figure 3 As shown, the heat-conducting back shell 5 includes an inner heat-conducting frame 51, an outer heat-conducting frame 52, a middle plastic frame 53, and connecting heat-conducting pillars 54; the lamp holder 1 is installed on the middle plastic frame 53, and the middle plastic frame 53 has several heat-conducting holes 531. The middle plastic frame 53 is the main mounting structure, and the lamp holder 1 is installed on the middle plastic frame 53. The material of the middle plastic frame 53 is a high-temperature resistant plastic material, such as PP, modified PPO, PEEK, PPS, etc. The material of the middle plastic frame 53 is determined according to the requirements and the actual temperature that the lamp board 2 can reach. The specific material is not limited here.
[0034] Several heat-conducting pillars 54 are provided, each corresponding to one of the heat-conducting holes 531, and are inserted into the heat-conducting holes 531. That is, the number of heat-conducting holes 531 is the same as the number of heat-conducting pillars 54. The heat-conducting pillars are inserted into the heat-conducting holes 531 one by one, and the length of the heat-conducting pillar 54 is longer than the depth of the heat-conducting hole 531. That is, when the heat-conducting pillar 54 is inserted into the heat-conducting hole 531, it will protrude a part of the heat-conducting hole 531, so that the heat-conducting pillar 54 cannot be completely located in the heat-conducting hole 531.
[0035] The inner heat-conducting frame 51 is located inside the middle plastic frame 53 and is connected to the end of the connecting heat-conducting column 54 near the inside of the middle plastic frame 53. The outer heat-conducting frame 52 is located outside the middle plastic frame 53 and is connected to the end of the connecting heat-conducting column 54 outside the middle plastic frame 53. The inner heat-conducting frame 51, the outer heat-conducting frame 52 and the connecting heat-conducting column 54 are all made of metal, such as stainless steel. If there is a weight requirement, aluminum can be used. Therefore, both the outer heat-conducting frame 52 and the inner heat-conducting frame 51 can transfer heat through the connecting heat-conducting column 54 to reduce the heat around the lamp panel 2.
[0036] Specifically, when the lamp panel 2 generates heat, the heat is absorbed by the inner heat-conducting frame 51 and transferred to the outer heat-conducting frame 52 through the connecting heat-conducting column 54. The outer heat-conducting frame 52 is located on the outside, so it directly exchanges heat with the outside air, thereby accelerating the heat dissipation speed of the outer heat-conducting frame 52. After the outer heat-conducting frame 52 cools down, it continues to transfer the heat of the inner heat-conducting frame 51 through the connecting heat-conducting column 54, so as to achieve the effect of cooling and absorbing heat around the lamp panel 2 and extending the service life of the overall work lamp.
[0037] The diameter of the heat-conducting column 54 is equal to the inner diameter of the heat-conducting hole 531, so it can block the heat-conducting hole 531. This achieves the heat conduction effect while preventing dust or moisture from entering the interior of the concave structure, thus ensuring the safe use of the lamp board 2.
[0038] If the mask 4 is not needed for light diffusion, it can be omitted and the lens 3 can be used directly for light transmission.
[0039] Furthermore, the inner heat-conducting frame 51 is installed tightly against the middle plastic frame 53, so that the connecting heat-conducting column 54 extends outward from the heat-conducting hole 531 with the inner heat-conducting frame 51 as the base point. The inner heat-conducting frame 51 is installed tightly against the inner wall of the middle plastic frame 53, so that the heat-conducting hole 531 can be closed by the inner heat-conducting frame 51, further preventing dust or moisture from entering the middle heat-conducting frame. Meanwhile, an interval space is formed between the outer heat-conducting frame 52 and the middle plastic frame 53, which increases the heat dissipation area of the outer heat-conducting frame 52. That is, the outer heat-conducting frame 52 does not contact the middle plastic frame 53, so that both the outer wall and the inner wall of the outer heat-conducting frame 52 can contact the air, thereby improving the heat dissipation efficiency.
[0040] Furthermore, the inner heat-conducting frame 51 is polished to form a reflective surface. After polishing, the surface of the inner heat-conducting frame 51 becomes smooth and reflective. When the lamp panel 2 shines on the inner heat-conducting frame 51, the reflective surface formed after polishing can be used to reflect the light towards the lens 3 and the mask 4, thereby achieving the effect of partial light focusing and reflection.
[0041] In some embodiments, reference Figure 4 As shown, due to the outer heat-conducting frame 52, when repairing or cleaning the work light, the worker will touch the outer heat-conducting frame 52. During the heat dissipation process, the surface of the outer heat-conducting frame 52 will generate heat. If the heat is too large, it may cause burns to the repair or cleaning personnel. Directly touching the outer heat-conducting frame 52 may also cause leakage. Therefore, a heat insulation shell 7 is provided on the outer wall of the middle plastic frame 53, and the heat insulation shell 7 covers the outer heat-conducting frame 52. The heat insulation shell 7 blocks the outer heat-conducting frame 52, so that when the repair worker or cleaning personnel come into contact with the work light, they will directly contact the heat insulation shell 7 instead of the outer heat-conducting frame 52, thereby achieving the prevention of burns and leakage, and improving the safety of the work light.
[0042] Furthermore, the outer heat-conducting frame 52 has several connecting ports 521, and the heat insulation shell 7 has heat insulation columns 71 corresponding to the connecting ports 521. After the heat insulation columns 71 pass through the connecting ports 521, they extend away from the middle plastic frame 53, so that the heat insulation shell 7 can be installed on the heat insulation columns 71. The heat insulation shell 7 can be connected to the outer wall of the middle plastic frame 53 by passing through the connecting ports 521 through the heat insulation columns 71. At the same time, the heat insulation shell 7 is not connected to the outer heat-conducting frame 52, so that the heat dissipation of the outer heat-conducting frame 52 will not be affected. The heat insulation shell 7 can also prevent maintenance personnel or cleaning personnel from touching the outer heat-conducting frame 52, so as to ensure heat dissipation and provide a safe use effect. At the same time, the heat insulation shell 7 can also shield the outer heat-conducting frame 52 from dust, preventing dust from accumulating on the outer heat-conducting frame 52 and affecting heat dissipation.
[0043] Furthermore, the diameter of the heat insulation column 71 is smaller than the inner diameter of the connecting port 521, so that the heat insulation column 71 passes through the middle of the connecting port 521, preventing the heat insulation column 71 from touching the outer heat-conducting frame 52 and blocking the connecting port 521. Therefore, it will not affect the heat dissipation of the outer heat-conducting frame 52. At the same time, opening several connecting ports 521 can also provide gas circulation and accelerate the heat dissipation efficiency of the outer heat insulation frame.
[0044] Furthermore, there is a gap between the heat insulation shell 7 and the outer heat-conducting frame 52. The gap between the heat insulation shell 7 and the outer heat-conducting frame 52 allows air or airflow to flow through the gap, so that the heat insulation shell 7 can cover the heat-conducting frame without affecting the heat dissipation efficiency of the outer heat-conducting frame 52. That is, the air around the outer heat-conducting frame 52 can flow through the gap between it and the heat insulation shell 7 to achieve heat exchange, and can also flow through the gap between the outer heat-conducting frame 52 and the middle plastic frame 53 to achieve heat exchange, thus providing stable heat dissipation while ensuring safety in use.
[0045] The heat insulation shell 7 can also have several heat dissipation holes to allow air to circulate between the space and the heat dissipation holes, thereby improving the heat dissipation efficiency of the outer heat-conducting frame 52.
[0046] The inner wall of the heat insulation shell 7 can be provided with a sliding groove, and the heat insulation column 71 is located in the sliding groove and is slidably connected to the sliding groove. When it is necessary to disassemble the heat insulation shell 7, the heat insulation shell 7 can be moved along the sliding groove through the heat insulation column 71 until it is separated from the groove opening. The separation of the heat insulation shell 7 makes it convenient to clean the heat insulation shell 7, and also makes it convenient to disassemble and repair the outer heat conduction frame 52 or the middle plastic frame 53.
[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
