LED lamps that dissipate heat through lenses

Abstract

The invention discloses a light-emitting diode (LED) lamp capable of transferring and dissipating heat through a lens. The LED lamp comprises a lamp base and a lampshade. The lens is installed on the lampshade. A printed circuit board (PCB) is installed inside the lampshade. An electric appliance control assembly and a plurality of LEDs are welded to the PCB. A base pin of each LED is provided with a bent part. The portion, close to an LED luminous body, of each bent part is provided with an elastic insulator. Each LED luminous body can be attached to the inner surface of the lens tightly through the elastic force generated by the corresponding bent part. Heat of each LED luminous body can be transferred and dissipated through the lens. The lens is a plane lens. Correspondingly, the top of each LED luminous body is a plane. The lens is made of glass. An included angle ranging from 5 degrees to 15 degrees is formed between the bent part of the base pin of each LED and the PCB. The lampshade is covered with a metal cover. The LED lamp further comprises a metal lens cover. The center of the metal lens cover is hollowed out. The lens is fixed to the metal cover through the metal lens cover. Through holes are formed in the portion, covered with the metal cover, of the lampshade. The lampshade is an insulated lampshade for improving the insulation performance. The LED lamp capable of transferring and dissipating heat through the lens has the beneficial effects of being simple in structure, low in cost and good in heat dissipation effect.

[0002] LED lamps are usually assembled on the same PCB board by many LEDs. In order to improve the brightness and luminous efficiency, the working mode of high brightness and high current is adopted, which causes the temperature to rise. If the maximum temperature of the LED cannot be effectively controlled, it will directly affect the LED life, reduce luminous efficiency

[0003] The way of heat dissipation usually includes heat conduction, heat radiation and air convection. Relatively speaking, the cost of air convection is relatively low, but air is a better heat insulation material, and the heat dissipation effect through air is poor. Therefore, the application number is 201010139375.8 The Chinese patent discloses an LED lamp

The LED lamp includes an LED chip, a heat dissipation base and a lampshade, the lampshade is fixed on the heat dissipation base, the LED chip is located in the lampshade, and the lampshade is filled with heat-conducting gas. The heat dissipation performance of the LED lamp of the invention is greatly improved. It can be lifted and can work better at lower temperatures, but the structure is complex and costly, and it is not easy to maintain

[0004] The effect of heat conduction is better, and the common heat dissipation method is to add heat sinks, etc., but the existing problems are high cost, complex structure, and large volume
