Heat-dissipation type LED (Light Emitting Diode) lamp

Abstract

The invention relates to the field of lamps and discloses a heat-dissipation type LED (Light Emitting Diode) lamp. The heat-dissipation type LED lamp comprises a lamp body, a lamp cap, a lamp holder and a lamp shade, wherein the lamp body is connected to the lamp cap; the lamp cap is in threaded connection with the lamp holder; the lamp shade covers the lamp body; foldable memory metal is connected between the lamp holder and the lamp shade; a plurality of holes are formed in the foldable memory metal; a first elastic sleeve is connected onto the lamp holder in a sliding manner; a second elastic sleeve sleeves the first elastic sleeve in the sliding manner; the second elastic sleeve is connected to the lamp shade; an expansion block is arranged between the second elastic sleeve and the lamp shade; a spring is connected between the first elastic sleeve and the memory metal; a first through hole is formed in the first elastic sleeve; a second through hole is formed in the second elastic sleeve; the first through hole and the second through hole are formed in a staggered manner; the first elastic sleeve is positioned on the outer side of the memory metal; the lamp shade is a transparent heating expansion body. Compared with the prior art, the heat-dissipation type LED lamp has the advantages of better heat dissipation effect, better illumination brightness, low production cost and long service life; the heat-dissipation type LED lamp can be popularized and used.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a heat dissipation LED lamp. Background technique [0002] LED lights have the advantages of high luminous efficiency, power saving and long life, so their applications are becoming more and more extensive. Since the LED lamp emits light, its own temperature will gradually increase. During the continuous operation of the lighting device, if the heat generated by the LED lamp cannot be dissipated in time, the LED lamp assembly will be damaged and the use of the lighting device will be affected. life. [0003] LED light bulbs in the prior art are generally dissipated by a separate heat sink. For example, a Chinese invention patent with a patent number of ZL201120307527.0 with an authorization announcement date of April 25, 2012 discloses a heat dissipation structure for a heat dissipation LED light bulb. The LED light bulb heat dissipation structure includes a light bulb bracket and heat sin...

Problems solved by technology

Although this method can play a role in heat dissipation, it needs to install more heat sinks, and the lamp cup part needs to be provided with multiple openings to install heat sinks, which makes the weight of the LED light heavy; when making this LED light , because the heat sink and the LED lamp body need to be made separately, and an opening for fixing the heat sink needs to be opened in the LED lamp body, so the manufacture of this LED lamp is relatively complicated and the production cost is high
