Abstract
The utility model discloses a LED fluorescent lamp, which comprises a transparent lampshade similar with the tube, a heat radiation rack and lamp holder covers on both ends; a LED substrate is disposed on the heat radiation rack; a LED lamp is enclosed on the LED substrate; the LED substrate is in electric connection with the electrode fixed on the lamp holder cover; and axial strip convex lens are disposed at least on the LED irradiation region on the transparent lampshade. The utility model achieves the advantages of high brightness, broad illumination angle and convenient assembling.
Description
Technical field
The utility model belongs to lighting field, is meant that specifically a kind of is the LED fluorescent lamp of light emitting source with the LED lamp.
Background technology
Fluorescent lamp is as cold light source, and traditional incandescent lamp of comparing is energy-conservation, is widely used in industry and domestic lighting.Along with the continuous development of semiconductor and electronic technology, LED is with its superior energy-efficient performance and obtain the approval in market longer service life.Therefore but it is very far away that LED lamp type, light path and traditional fluorescent lamp are compared, and develops a kind ofly to promote for LED as the LED sight lamp of light emitting source and energy-conservation significant with the LED lamp.At present, also disclose in patent gazette and severally done the mentality of designing of the LED fluorescent lamp of light emitting source with the LED lamp, come out but the common issue with of its existence is the diffusion of LED light path, the brightness of irradiation area is lower.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of brightness height, the wide LED fluorescent lamp of lighting angle are provided.
For achieving the above object, the technical solution of the utility model is, include the lamp holder lid at the Transparent lamp shade that is similar to the fluorescent tube shape and heat radiation rack, two ends, described heat radiation rack is provided with the LED substrate, be packaged with the LED lamp on this LED substrate, and this LED substrate is electrically connected with being fixed on the electrode that lamp holder covers, and described Transparent lamp shade LED irradiation area at least is provided with axial strip convex lens.Convex lens is passed through in this setting, the LED lamp is emitted beam compile, and has improved the light luminance of LED fluorescent lamp.
As the further of technique scheme improved and replenish, the utility model also preferably has following technical scheme, and two axial strip convex lens that are symmetricly set in LED lamp both sides are arranged on the described Transparent lamp shade.This setting is by two axial strip convex lens, and the light that makes the LED lamp send is gone out through two angular emission, has improved the lighting angle of LED fluorescent lamp.
The avris of described heat radiation rack is provided with the heat radiation wing, be arranged at the strip mounting groove of LED substrate scarf on the upper surface of this heat radiation rack, the both sides of this mounting groove are provided with the chute of strip, and the both wings of described Transparent lamp shade are provided with the slide plate of joining with chute axial slip, circumferential card.Be convenient to the assembling of LED substrate and Transparent lamp shade by this setting.
The bottom of described heat radiation rack is installed with heat sink.By this setting, improved the radiating efficiency of heat radiation rack.
Below in conjunction with specification drawings and specific embodiments, the utility model is done further introduction.
