Problems solved by technology

However, on the one hand, due to the small internal space of LED lamps, the volume of the fan is restricted, so it is impossible to generate a large air volume, and it is difficult to ensure the cooling effect; on the other hand, the life of the fan is short, which is difficult to match the life of the LED, and the noise of the fan Disturbing, these are the defects of fan cooling
[0004] Although the above measures have indeed played a certain role in heat dissipation, the effect of heat dissipation is not ideal, and a better heat dissipation method needs to be sought

Abstract

The invention relates to an LED (light-emitting diode) lamp, and in particular relates to an LED lamp for radiating heat by using ultrasonic waves. The LED lamp comprises an LED lamp with a heat radiator made of a metal material, wherein an ultrasonic generator is embedded into the LED lamp. According to the LED lamp for radiating the heat by using ultrasonic waves, the ultrasonic technology is firstly applied to the heat radiation of the LED lamp; and practices prove that the LED lamp for radiating the heat by using the ultrasonic waves has good heat-radiating effect and is easy to realize.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp utilizing ultrasonic waves to dissipate heat. Background technique [0002] As we all know, LED lamps have the advantages of high efficiency, long life, energy saving and environmental protection, and their use is becoming more and more extensive. When the LED lamp is lit, the LED lamp beads convert about 30% of the electric energy into visible light, and about 70% of the electric energy is converted into heat. Therefore, the LED lamp will generate a lot of heat when it is lit, and the volume of the LED lamp bead Small, so that the heat flux density is high. If the LED lamp cannot dissipate the heat in time, it will aggravate the light decay of the LED lamp beads and greatly shorten the life of the lamp. [0003] At present, the most common heat dissipation method is to add a metal heat sink to the LED lamp bead. Usually, the shape of the heat sink is designed according to the shape o...
