Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp with good heat dissipation effect. Background Art

[0002] In modern lighting technology, LED lamps, with their high efficiency, long lifespan, and environmentally friendly features, have gradually become mainstream products in the lighting field. However, with the increase in LED lamp power and the strengthening trend of dense design, heat dissipation issues have become increasingly prominent, becoming a key factor restricting the performance and lifespan of LED lamps.

[0003] LED lamps generate a significant amount of heat during operation. This heat primarily stems from energy loss during the electro-optical conversion process of the LED chip. If this heat cannot be dissipated promptly and effectively, the LED chip temperature will rise, leading to a series of problems. First, high temperatures accelerate the aging process of LED chips, shortening their service life. Second, high temperatures reduce the luminous efficacy and color temperature stability of LED lamps, affecting lighting quality. Furthermore, excessively high temperatures can pose safety risks, such as short circuits and insulation failure. Utility Model Content

[0021] Working principle: When the LED lamp is working, the electronic component body 5 will generate heat. The heat is first conducted through the direct contact heat conducting plate 1 6. The heat of the heat conducting plate 1 6 is further transferred to the heat collecting plate 8 through the heat conducting plate 2 9 fixed on both sides of its top. The heat collecting plate 8 serves as a heat collection point. Its design is to efficiently receive and distribute the heat from the heat conducting plate 2 9. The heat is transferred to the external transverse heat sink 18 through the heat conducting plate 3 17. The design of the transverse heat sink 18 increases the heat dissipation area and promotes air convection through the heat dissipation holes 24 on its surface, accelerating the dissipation of heat. The heat is transferred to the heat sink 20 through the heat conducting plate 4 19. The heat dissipation groove 23 on the top of the heat sink 20 further increases the heat dissipation area and improves the heat dissipation efficiency. The heat is transferred to the wavy heat sink 22 through the heat conducting plate 5 21. The wavy heat sink 22 not only increases the heat dissipation area, and its unique shape also enhances air flow and improves the heat dissipation effect. In order to further improve the heat dissipation efficiency, a micro induced draft fan 10 is installed inside the lamp holder 1. The micro induced draft fan 10 sucks hot air in the groove 7 through the heat absorption pipe 11. The hot air contains heat transferred from the heat collecting plate 8 through the heat conducting plate 2 9, the heat conducting plate 3 17, the heat conducting plate 4 19, and the heat conducting plate 5 21. The micro induced draft fan 10 discharges the sucked hot air through the exhaust pipe 13, and the exhaust pipe 13 guides the hot air to the outlet pipe 12. The outlet pipe 12 is located on the outer surface of the lamp holder 1 to facilitate the discharge of hot air. In order to further enhance the heat dissipation effect, a ventilation net 15 is designed at the bottom of the lamp holder 1. The ventilation net 15 allows external cold air to enter the cavity 3 and exchange with the hot air in the groove 7 through the ventilation holes 16, thereby promoting the natural convection of heat.

[0022] In summary: the LED lamp with good heat dissipation effect forms an efficient heat conduction path through the close connection of heat conducting plate 1 6, heat conducting plate 2 9 and heat collecting plate 8, which quickly transfers the heat generated by the electronic component body 5 to the heat collecting plate 8, effectively avoiding the accumulation of heat inside the lamp holder 1, and significantly reducing the working temperature of the LED chip. The heat conducting plate 3 17, heat conducting plate 4 19 and heat conducting plate 5 21 connected to the top of the heat collecting plate 8 transfer heat to the external transverse heat sink 18, heat sink 20 and wavy heat sink 22 respectively. These heat dissipation structures greatly increase the heat dissipation area and improve the heat dissipation efficiency. In particular, the design of the wavy heat sink 22 not only increases the heat dissipation area, but also enhances air convection through its special shape, further improving the heat dissipation effect. The introduction of the micro-induced draft fan 10 is sucked into the groove through the heat absorption pipe 11 7, and discharges the hot air to the outside of the lamp holder 1 through the exhaust pipe 13 and the outlet pipe 12, realizing active heat dissipation and significantly improving the heat dissipation efficiency. At the same time, the design of the air outlet net 14 in the outlet pipe 12 not only ensures the heat dissipation effect, but also prevents external debris from entering the interior of the lamp holder 1, thereby ensuring the safe operation of the lamp. The design of the heat dissipation groove 23 on the top of the heat dissipation plate 20 and the heat dissipation holes 24 on the surface of the horizontal heat sink 18 not only increases the heat dissipation area, but also promotes air convection, further improves the heat dissipation efficiency, and ensures the luminous efficacy and color temperature stability of the LED lamp under long-term operation. The design of the ventilation net 15 and the ventilation holes 16 not only ensures the air circulation inside the lamp holder 1, but also facilitates the entry of external cold air and the exhaust of internal hot air, further reducing the temperature inside the lamp and improving the safety and reliability of the lamp.
