Abstract

The invention discloses an LED fluorescent lamp with a large light emitting angle, and belongs to the technical field of LED illumination lamps. The LED fluorescent lamp comprises an optically designed lamp cover, and a lamp holder with a circularly arched cross section, wherein the lamp cover and the lamp holder are buckled to take a cylindrical shape; a lamp tube inner hole forms an accommodating space; an aluminum baseplate clamping groove, a bar-shaped aluminum baseplate, a light emitting module, a barb, a lamp cover clamping groove and a heat dissipating aluminum piece are arranged in the accommodating space; the splayed heat dissipating aluminum piece is connected to the two ends of the aluminum baseplate clamping groove; the aluminum baseplate clamping groove and the heat dissipating aluminum piece are connected as an integrated structure; the inclination of the heat dissipating aluminum piece is within 180-240 degrees; and the radian of the lamp cover is larger than the radian of the lamp holder. Light rays are fully reflected and diffused through the specially designed lamp cover, so that the light emitting rate reaches 94%; the light emitting angle reaches 180-240 degrees through the heat dissipating aluminum piece with adjustable inclination angle; and the LED fluorescent lamp with the large light emitting angle improves the scattering efficiency, increases the light emitting angle of the light rays, reduces the irradiation dead angle, and enhances the light emitting strength and uniformity of the lamp cover.

Description

technical field [0001] The invention relates to the technical field of LED lighting fixtures, in particular to an LED fluorescent lamp with a large light emitting angle. Background technique [0002] In the context of rising concerns about global energy shortages, saving energy is an important issue we are currently facing. Compared with traditional light sources, light-emitting diodes (LEDs) have the advantages of higher luminous efficiency, low radiation, low power consumption, long life, low driving voltage, fast startup, environmental protection, shock resistance and pressure resistance, and miniaturization of lamps and lanterns. A series of applications such as various indications, displays, general lighting, etc. In the prior art, the light angle of common LED fluorescent lamps is mostly 120°, and the dark areas on both sides of the lamps are relatively large, so for some occasions, it cannot meet people's use requirements. In addition, the general lampshade has the ...
