Heat dissipation structure of led lamp and led energy-saving lamp adopting the heat dissipation structure

Abstract

The invention discloses a heat dissipation structure of an LED lamp and an LED energy-saving lamp adopting the heat dissipation structure, wherein the first heat dissipation component is an outer heat dissipation component of the LED light heat dissipation structure, and the second heat dissipation component is an inner heat dissipation component of the LED light heat dissipation structure; The outer surface of the second heat dissipation member is connected with a plurality of protruding second heat dissipation fins. A heat dissipation fin, the bottom end of the inverted first heat dissipation member and the outside of the second heat dissipation member leave a heat dissipation height separation space that conducts the heat generated by the LED chip to the second heat dissipation member and quickly radiates it in the convective air. With sufficient heat dissipation area, it has more heat dissipation area than conventional heat dissipation aluminum parts, and has more convective air flow, which can quickly generate air convection in the inner and outer cavity of heat dissipation aluminum parts, and achieve the effect of rapid heat evacuation.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a heat dissipation structure used in the LED lamp and an LED energy-saving lamp adopting the heat dissipation structure. Background technique [0002] Light-emitting diodes (LEDs) are widely used in lighting fixtures and electronic devices as light sources because of their advantages such as high brightness, low power consumption, and long service life; LED lighting technology is also increasingly used in office buildings , Shopping malls, supermarkets, schools, hospitals, hotels, factory workshops, homes and other indoor and outdoor lighting places, almost completely replace traditional fluorescent lamps; while the heat dissipation structure of LED lighting products on the existing market is generally composed of aluminum substrates, cooling fins Chips and other components to realize the heat dissipation effect on the LED chip, but the heat dissipation structure of this kind of LED lamp has a poor...

Problems solved by technology

[0003] The present invention solves the problem that the heat dissipation structure of the existing LED lighting products has a poor heat dissipation effect on the LED chip, and the heat dissipation is not timely, the heat dissipation effect is poor, and it is easy to cause the temperature of the LED chip of the lamp to be too high and burn out the chip. The service life of the LED chip is shortened, and ultimately the service life and performance of the entire LED energy-saving lamp are reduced. The current situation provides a method that can improve the heat dissipation effect of the LED chip to a greater extent, and achieve the goal of improving the working performance and service life of the LED chip.
