Light emitting diode (LED) lamp emitting rotary spot light

Abstract

The invention discloses a light emitting diode (LED) lamp emitting rotary spot light, and the LED lamp comprises a heat radiation body, a lamp holder and a lampshade; the heat radiation body is connected to the top of the lamp holder; the lampshade is connected to the top of the heat radiation body; the exterior of the heat radiation body is provided with a rotary wall; the rotary wall is provided with a plurality of heat radiation through holes; a substrate is arranged inside the heat radiation body, and the outer surface of the substrate is provided with a plurality of LED lamp beads; the substrate is electrically connected with the lamp holder through a drive element; the rotary wall is driven by the drive element to rotate along the heat radiation body; the heat radiation body is made of a transparent or translucent material; and the rotary wall is made of a lightproof material. The LED lamp emitting the rotary spot light is attractive in structure and capable of emitting alternately-bright-dark light through the structure of the heat radiation part and the variation of the transmission performance of the material; and the continuously-rotary artistic light which is alternately bright and dark and has a gradual changing effect can be projected on the medium of the back part of a light source due to the rotary structure of the rotary wall.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp emitting rotating spot lights with a beautiful structure and light effect, and belongs to the technical field of LED lighting components. Background technique [0002] As a new lighting source, LED lamp has the advantages of small size, low energy consumption, high luminous intensity, long service life and environmental protection. It has excellent energy-saving effect and is a green light source. However, because the work of LEDs consumes electric energy, part of it is converted into high-brightness light energy, and most of it is converted into heat energy, so LED lights will generate a lot of heat, and if this part of heat is not dissipated in time, when it exceeds a certain value , the luminous intensity and life of LED lights will be seriously attenuated, and even cause permanent damage, which greatly shortens the service life of LED lights, so LED lights must have a good heat diss...

Problems solved by technology

However, because the work of LEDs consumes electric energy, part of it is converted into high-brightness light energy, and most of it is converted into heat energy, so LED lights will generate a lot of heat, and if this part of heat is not dissipated in time, when it exceeds a certain value , the luminous intensity and life of LED lights will be seriously attenuated, and even cause permanent damage, which greatly shortens the service life of LED lights, so LED lights must have a good heat dissipation structure; and with social progress, living standards continue to improve People have higher requirements for lighting and light effects in homes or public places. Therefore, it is necessary to design some LED lights with beautiful structures, especially LED lights that emit light with artistic effects.
