Description

Technical Field

[0001] The utility model relates to the field of LED lens lamps, in particular to a high-power LED lens lamp and a heat dissipation structure thereof. Background Art

[0002] With the increasing use of LED lens lights, their heat dissipation issues are receiving increasing attention. The traditional first-generation LED lens lights used a heat-conducting structure that fixed the direct-beam lamp plate (i.e., the high-beam lamp mounting plate) to a direct-beam heat dissipation aluminum block, allowing the block's natural heat dissipation to reduce the temperature of the high-beam lamp beads. The disadvantage of this structure is that since the direct-beam heat dissipation aluminum block is fixed on top of the low-beam main radiator, its size is limited by the space at the top of the car's headlights. This results in a relatively small direct-beam heat dissipation aluminum block and the inability to install a fan, resulting in suboptimal heat dissipation. External temperatures can reach over 80°C, making it only suitable for low-power lamp beads and unsuitable for high-power LED lamp beads.

[0003] Through research and development, improvements to the current direct heat dissipation structure have significantly increased the stable power of high-beam lamp beads by increasing the heat dissipation area of the aluminum heat sink and adding a fan. However, this improved technology is limited to improving the stable power of high-beam lamp beads and has not significantly improved the power of low-beam lamp beads. Furthermore, with the current market demand for smaller and shorter lamp bodies, how to simultaneously reduce the temperature of high and low beam lamp beads and improve their stable power has become a technical challenge that needs to be improved.

[0004] This application is based on this and creates a new high-power LED lens lamp and its heat dissipation structure, which can overcome the defect of existing LED lens lamps that they cannot simultaneously reduce the temperature of high and low beam lamp beads, so as to truly solve the heat dissipation problem of LED lens lamps and enhance the market competitiveness of high-power LED lens lamps. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a heat dissipation structure of a high-power LED lens lamp, which can reduce the temperature of the high and low beam lamp beads at the same time by improving the direct heat dissipation shell and adding a centrifugal fan and an exhaust fan, as well as a heat pipe and a heat dissipation fin, thereby truly solving the heat dissipation problem of the LED lens lamp, meeting the requirements of the high-power LED lens lamp, and thus overcoming the shortcomings of the existing LED lens lamp.

[0006] In order to solve the above technical problems, the utility model provides a heat dissipation structure of a high-power LED lens lamp, wherein the LED lens lamp includes LED low-beam lamp beads and LED high-beam direct lamp beads, the low-beam lamp beads are fixed to the main heat dissipation shell through the low-beam lamp plate, and the high-beam direct lamp beads are fixed to the main heat dissipation shell through the direct heat dissipation block. The direct heat dissipation block adopts a direct heat dissipation shell, and the front end of the direct heat dissipation shell is used to install high-power high-beam direct lamp beads. The front part of the direct heat dissipation shell is provided with a centrifugal fan for blowing external cold air to the periphery of the high-beam direct lamp beads, and the rear part of the direct heat dissipation shell is provided with an exhaust fan for taking out the heat inside the shell.

[0007] A further improvement includes heat pipes arranged along the front and rear ends of the direct heat dissipation shell, which are used to transfer heat from the front end of the direct heat dissipation shell to its rear end, and the exhaust fan takes away the heat.

[0008] As a further improvement, the heat pipe adopts a U-shaped bending structure, the U-shaped bending portion is arranged close to the front end of the direct heat dissipation shell, and the U-shaped opening end is arranged close to the exhaust fan.

[0009] A further improvement includes a heat dissipation fin connected to the low beam light panel, and the heat dissipation fin is arranged on a side close to the exhaust fan.

[0010] As a further improvement, the direct heat dissipation housing and the main heat dissipation housing are both made of aluminum, and the heat dissipation fins are made of copper heat dissipation teeth.

[0011] A further improvement includes a main cooling fan arranged at the rear end of the main cooling shell, which is used to blow external cold air into the interior of the main cooling shell, and the cooling fins are arranged in the air path between the main cooling fan and the exhaust fan.

[0012] As a further improvement, a hollow cover plate is provided on the outer side of the centrifugal fan.

[0013] As a further improvement, the middle and rear parts of the direct heat dissipation housing are fixedly connected to the main heat dissipation housing by bolts.

[0014] As another improvement of the present invention, the present invention further provides a high-power LED lens lamp, which includes the heat dissipation structure of the high-power LED lens lamp.

[0015] As a further improvement, a high-power high-beam direct lamp bead is respectively provided on both sides of the front end of the direct heat dissipation shell, and the centrifugal fan is arranged on the shell between the two high-beam direct lamp beads to provide cold air for the two high-beam direct lamp beads.

[0016] After adopting such a design, the utility model has at least the following advantages:

[0017] 1. The heat dissipation structure of the high-power LED lens lamp of this utility model improves the structure of the direct heat dissipation shell, making it easy to install a centrifugal fan and an exhaust fan to achieve air ventilation inside and outside the shell, accelerate the heat dissipation of the lamp beads, and improve the heat dissipation effect.

[0018] 2. By adding heat dissipation fins, the temperature of the low beam lamp beads can be reduced at the same time, which can more effectively solve the heat dissipation problem of the high and low beams of the LED lens lamp.

[0019] 3. By adding heat pipes, the heat of the high-power high-beam direct lamp beads is facilitated to be conducted from front to back, meeting the heat dissipation needs of the high-power LED high-beam direct lamp beads, and truly solving the problem of poor heat dissipation effect of high-power LED lens lamps.

[0020] 4. The main cooling fan is also set up so that it can cooperate with the exhaust fan to better remove the heat from the cooling fins in time, effectively solving the problem of heat dissipation from the low beam lamp beads.

[0021] 5. Through its improved heat dissipation structure, this new high-power LED lens lamp not only reduces the ambient temperature of the front direct-illumination lamp beads through a centrifugal fan, but also uses an exhaust fan to centrally extract heat from the heat sink fins of the low-beam lamp panel and the heat drained by the heat pipe, achieving the goal of simultaneously reducing the temperature of the high and low beam lamp beads. At the same time, it significantly improves the stable power of the high and low beam lamp beads, making the heat distribution within the lamp body more uniform. This truly solves the problem of shortened service life of high-power LED lens lamps due to poor heat dissipation, allowing high-power LED lens lamps to achieve maximum power, extend service life, and enhance the market competitiveness of high-power LED lens lamps. Furthermore, this structure makes the entire lamp body rationally designed, compact, aesthetically pleasing, and highly recognizable. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Refer to the attached Figure 1 and 2 As shown, the high-power LED lens light of this embodiment includes an LED low-beam lamp bead and an LED high-beam direct lamp bead 10. The low-beam lamp bead is fixed to the main heat dissipation housing 1 through a low-beam lamp plate, and the high-beam direct lamp bead 10 is fixed to the main heat dissipation housing 1 through a direct heat dissipation housing 2, realizing the high and low beam illumination of the LED lens light.

[0032] Refer to the attached Figures 2 to 5 As shown, the direct heat dissipation housing 2 in this embodiment adopts a semi-encircling structure and is fixed to the upper portion of the main heat dissipation housing 1, for example, by means of external bolts 11 and internal bolts 12. Two front claws extend from both sides of the front end of the direct heat dissipation housing 2 for mounting high-power LED high-beam direct lamp beads 10.

[0033] The improvement of the direct heat dissipation housing 2 of this embodiment is that a centrifugal fan 21 is provided at the front thereof for blowing external cold air to the periphery of the high beam direct light bead 10. Figure 5 As shown, the centrifugal fan 21 is fixed by bolts 13. In this way, the centrifugal fan 21 can provide cool air to the interior of the direct heat dissipation housing 2. In particular, the centrifugal fan 21 provides wind blowing in all directions, which is more conducive to reducing the temperature of the high-power LED high-beam direct lamp beads 10. In addition, the rear part of the direct heat dissipation housing 2 is provided with an exhaust fan 22 for taking out the heat inside the housing. As shown in the attached figure Figure 6As shown, the exhaust fan 22 is fixed to the direct heat dissipation housing 2 by bolts 14 and fan fixing rings 15. In this way, the exhaust fan 22 can take out the heat inside the direct heat dissipation housing 2 and the main heat dissipation housing 1, thereby reducing the temperature inside the housing.

[0034] In a preferred embodiment, the direct heat dissipation housing 2 is further provided with heat pipes 23 arranged along the front and rear ends of the direct heat dissipation housing 2. The heat pipes 23 adopt an existing heat pipe structure with good conduction performance, which can promptly transfer heat from the front end of the direct heat dissipation housing 1 to its rear end, and then be carried out of the housing by the exhaust fan 22, thereby better achieving the purpose of reducing the temperature of the high-power high-beam direct lamp beads 10 and improving the stability of the high-beam.

[0035] Specifically, the heat pipe 23 in this embodiment adopts a U-shaped bending structure, and its U-shaped bending portion is arranged close to the front end of the direct heat dissipation housing 2, as shown in the attached Figure 7 and 8 As shown, the heat pipe 23 is fixed to the direct heat dissipation housing 2 by an aluminum pressing sheet 17 and a bolt 16. The U-shaped opening is arranged near the periphery of the exhaust fan 22 to better transfer the heat generated by the high-power high-beam direct lamp bead 10, which is conducive to heat dissipation.

[0036] In a preferred embodiment, the heat dissipation mechanism of the high-power LED lens light further includes heat dissipation fins 24 connected to the low-beam light board, which are used to increase the heat dissipation area of the low-beam light board. Heat from the low-beam lamp beads is transferred to the heat dissipation fins 24 through the low-beam light board, and then dissipated. In this embodiment, the heat dissipation fins 24 are located on a side near the exhaust fan 22, so that the exhaust fan 22 can promptly remove the heat dissipated by the heat dissipation fins 24 from the housing.

[0037] In this embodiment, the direct heat dissipation housing 2 and the main heat dissipation housing 1 are both made of aluminum, and the heat dissipation fins 24 are made of copper heat dissipation teeth, both of which can achieve good heat conduction and heat dissipation effects.

[0038] Furthermore, the heat dissipation mechanism of the high-power LED lens light also includes a main cooling fan disposed at the rear end of the main cooling housing 1, which is used to blow external cooling air into the interior of the main cooling housing 1. In this embodiment, the cooling fins 24 are disposed in the air path between the main cooling fan and the exhaust fan 22, which can more effectively and timely remove heat from the cooling fins 24, further meeting the requirement of simultaneous cooling of the high and low beam lamp beads.

[0039] In this embodiment, a hollow cover plate 25 is further provided on the outer side of the centrifugal fan 21 for protecting the centrifugal fan 21. Figure 2 As shown, the hollow cover plate 25 is fixed to the direct heat dissipation housing 2 by bolts 18 and also serves to protect the heat pipe 23 .

[0040] The heat dissipation structure of this new high-power LED lens lamp improves the direct heat dissipation housing, enabling the installation of a centrifugal fan and exhaust blower. This not only directly blows air to the high-beam direct-beam lamp beads, but also promptly extracts heat from the heat dissipation fins and heat pipes, simultaneously reducing the temperature of the high- and low-beam lamp beads, while simultaneously increasing the stable power of the high- and low-beam lamp beads and achieving more uniform heat distribution within the lamp body. This truly solves the problem of shortened service life of high-power LED lens lamps due to poor heat dissipation, allowing the lens lamp to achieve maximum power and extend its service life. Furthermore, the improvements to the direct heat dissipation housing structure make the entire lamp design more reasonable, more compact, and aesthetically pleasing, with high recognition.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which fall within the scope of protection of the present invention.
