Problems solved by technology

The intensive use of LEDs will cause a large amount of heat generated by LEDs to accumulate in a small space and cannot be dissipated in time
As the heat is difficult to dissipate in time, the temperature of the LED will rise, which will cause the LED's luminous performance to decay and rap

Abstract

The invention discloses an LED fluorescent lamp which comprises a body, a heat-conducting pad, an insulating pad, a lampshade, a plurality of LEDs and a substrate used for fixing the LEDs. One side of the body is provided with a radiator while the opposite side is provided with a first groove, two opposite upper groove rims of the first groove of the body are respectively provided with expansion parts, an opening edge of the lampshade is provided with clamping parts respectively clamped with the expansion parts of the two rims, the insulating pad is placed in the first groove of the body, the insulating pad is provided with a second groove, and the heat-conducting pad and the substrate are orderly fixed in the second groove of the insulating pad. Heat energy emitted from the LEDs is rapidly conducted to the body by orderly arranging the heat-conducting pad and the insulating pad under the substrate, thus greatly improving the radiation effect.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED fluorescent lamp. Background technique [0002] LED has the characteristics of high luminous efficiency, power saving and long life, and its application is more and more extensive. However, the amount of light emitted by a single LED is limited. If it is used for lighting such as fluorescent lamps, multiple LEDs must be densely arranged together for intensive use. Intensive use of LEDs will cause a large amount of heat generated by LEDs to accumulate in a small space and cannot be dissipated in time. As the heat is difficult to dissipate in time, the temperature of the LED will rise, which will cause the LED's luminous performance to decay and rapidly age, and the service life will be greatly reduced. [0003] At present, most LED fluorescent lamps on the market use air convection in the tube cavity to dissipate heat. LED fluorescent lamps with this structure have poor ...
