Abstract
The utility model is suitable for indoor illumination, and provides an LED fluorescent lamp, which comprises a circuit board, an LED in plug-in connection with the circuit board, and a heat radiation base connected with the circuit board, wherein the heat radiation base is provided with two side walls and a bottom plate connecting the two side walls, two side edges of the circuit board respectively extend into the two side walls, and insulating and heat conducting materials are filled in a gap enclosed by the circuit board and the heat radiation base. The insulating and heat conducting materials are in surface contact with both the circuit board and the heat radiation base, and the circuit board and the heat radiation base form a heat conduction entity to facilitate the heat conduction. When the fluorescent lamp is lighted, heat radiated from an LED chip is transmitted to the circuit board via an LED pin, the heat on the circuit board is transmitted to the heat radiation base rapidly via the insulating and heat conducting materials, and the heat accumulated on the heat radiation base is transmitted to the surrounding area through air convection, with direct heat transmission, fast heat conduction, and good radiating effect. The LED fluorescent lamp has longer service life as compared with common LED fluorescent lamps.
