Problems solved by technology

[0006] The purpose of the present invention is to provide a LED lamp with a heat sink to solve the problem in the above-mentioned background technology: the turntable on the fixed plate is driven by a micro motor to rotate, so that the connecting wire on the turntable pulls the high-temperature-resistant fan plate to move left and right. To solve the problem of slow conduction of the temperature in the light box on the heat sink, and then the high-temperature gas flowing out of the high-temperature resistant fan plate is absorbed by the heat conduction plate on the aluminum plate group, and the heat conduction plate transfers heat to the copper tube at the same time. After entering the copper tube, the water between the graphene scraps is evaporated, which is used to solve the problem of slow conduction of high temperature by the heat sink

Embodiment 1

[0030] The heat dissipation of LED lights is divided into active heat dissipation and passive heat dissipation. Active heat dissipation is mainly to install cooling fans and other devices to improve the flow of air around the LED lights. Passive heat dissipation is mainly to install heat dissipation fins to divert the heat generated by the LED lights. Traditional heat sink materials For aluminum alloy or copper material, the thermal conductivity of aluminum can reach 209 watts per meter Kelvin, the processing characteristics are very good, and the cost is low, so it is widely used; the thermal conductivity of copper is 390 watts per meter Kelvin, which is 70% higher than that of aluminum, but it has disadvantages It is about three times heavier than aluminum, and it is difficult to process. In addition to these two materials, some materials that increase heat dissipation, such as carbon-based compound materials and metal powder sintered materials; The three components are used ...

Embodiment 2

[0037] In order to further increase the flow speed of the high temperature in the light box 1, active heat dissipation assistance is required at this time. A micro motor 7 is installed on one side of the fixed plate 8, and the micro motor 7 is connected to the turntable 10 on the other side of the fixed plate 8. The turntable 10 A rotating column 15 is installed on the rotating column 15, and a connecting wire 11 is bound on the rotating column 15. At the same time, a rotating shaft 14 that can be rotated is installed on the entire fixed plate 8. The rotating shaft 14 is covered with a high temperature resistant fan plate 12. A spring 13 is installed between them. When a group of high temperature resistant fan plates 12 vibrates, it will be transmitted to all high temperature resistant fan plates 12 through the spring 13, so that the whole high temperature resistant fan plate 12 will vibrate;

[0038] One end of the three groups of high temperature resistant fan plates 12 is co...

Abstract

The invention discloses an LED lamp with cooling fins, and relates to the technical field of LED lamp heat dissipation, the LED lamp comprises a lamp box, a lampshade, a reflector, an aluminum substrate and lamp wicks, the lampshade is fixed on one side of the lamp box through bolts, the aluminum substrate and the reflector are installed on one side of the lamp box and located in the lampshade, and the lamp wicks are evenly fixed on one side of the aluminum substrate through spot welding; a rotary disc on a fixing plate is driven by a micro motor to rotate, so that a connecting line on a rotary column pulls high-temperature-resistant fan plates to move left and right, springs are installed between the high-temperature-resistant fan plates, vibration is formed between the high-temperature-resistant fan plates, air in a lampshade flows outwards, heat generated by a lamp wick can be discharged in time, and the heat dissipation efficiency is improved. The situation that the service life of the lamp wick is shortened due to the fact that the temperature between the aluminum substrate and the fixing plate is too high is prevented, and then high-temperature gas flowing out of the high-temperature-resistant sector plate is absorbed by the heat conduction pieces on the aluminum plate set.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of LED lamps, in particular to an LED lamp with heat sinks. Background technique [0002] LED lighting is recognized as the next-generation lighting technology due to its power saving, environmental protection and long life, and will replace various existing lighting technologies. There must be heat dissipation measures. Although the LED lighting technology has developed by leaps and bounds, and there are reports that the light emission per watt reaches 200lm, LED heat dissipation is a very headache in LED lighting, but it has not been effectively solved, and it has become the popularization of LED lighting. Obstacles on the road of development; [0003] The heat dissipation of LED lights is divided into active heat dissipation and passive heat dissipation. Active heat dissipation is mainly to install cooling fans and other devices to improve the flow of air around the LED lights. Passiv...
