Abstract
An LED lamp tube with an improved illumination effect comprises an aluminum alloy heat radiator, a PC (poly carbonate) light-permeable shade, an LED lamp bar and lamp holders. The aluminum heat radiator and the PC light-permeable shade are fastened to form a circular lamp tube in an embedded manner, the LED lamp bar is arranged in the lamp tube and attached on the aluminum alloy heat radiator, and the lamp holders are arranged at ends of the lamp tube. The LED lamp tube with the improved illumination effect is characterized in that by taking a practical light-shading position of the aluminum alloy heat radiator as an interface, the area ratio of cross sections of the aluminum alloy heat radiator and the PC light-permeable shade is 1:1.5-2.5. Preferably, the LED lamp tube further comprises a diffusing reflective cover and solves the problems that emitting angle is small and zebra strips and severe dazzling are caused in the prior art.
Description
Technical field
The utility model relates to a kind of LED fluorescent tube that has improved lighting effect, and it belongs to LED light fixture class.
Background technology
The LED lighting has now obtained using widely as third generation energy-conserving light source.In the LED lighting, the LED fluorescent tube is a kind of important use type product wherein, described LED fluorescent tube generally is made of aluminium alloy radiator, PC diffuser, LED lamp bar and lamp holder, described aluminium alloy radiator connects the formation round lamp tube with PC diffuser inlay card, described LED lamp bar is arranged in the fluorescent tube, and attach and to be located on the aluminium alloy radiator, described lamp holder is arranged on two ends of fluorescent tube.The problem that prior art exists is the fluorescent tube that is formed as one by aluminium alloy radiator and PC diffuser inlay card, if be interface with the actual shading of aluminium alloy radiator position, then the aluminium alloy radiator is generally about 1:1 with the area ratio of PC diffuser cross section, such structure is because the cross-sectional area of aluminium alloy radiator is excessive, directly caused the lighting angle of LED fluorescent tube little, the little then plane of illumination of lighting angle is also little, simultaneously in this case, zebra-stripe appears on the plane of illumination easily, dazzle is serious, and obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide a kind of LED fluorescent tube that has improved lighting effect, to overcome the problem that prior art exists.
A kind of LED fluorescent tube that has improved lighting effect of the present utility model, comprise that aluminium alloy radiator, PC diffuser, LED lamp bar and lamp holder constitute, described aluminium alloy radiator connects the formation round lamp tube with PC diffuser inlay card, described LED lamp bar is arranged in the fluorescent tube, and be attached on the aluminium alloy radiator, described lamp holder is arranged on the termination of fluorescent tube, it is characterized in that with the actual shading of aluminium alloy radiator position be interface, described aluminium alloy radiator is 1:1.5 ~ 2.5 with the area ratio of PC diffuser cross section.
As preferably, described LED lamp bar is attached on the aluminium alloy radiator intracavity bottom position, set up reflector layer on the described LED lamp bar, the described LED lamp bar left and right sides is provided with left LGP and right LGP, and described left LGP and right LGP form a light-guiding shade of dispersing.
This LED fluorescent tube that has improved lighting effect of the present utility model, the area ratio of the cross section by reducing aluminium alloy radiator PC diffuser, strengthened the lighting angle of LED fluorescent tube, thereby overcome the little problem of plane of illumination that prior art exists, by increasing reflector layer and increased the light-guiding shade that is formed by left LGP and right LGP at LED lamp bar, then effectively improved on the plane of illumination that prior art exists and zebra-stripe and the serious problem of dazzle occur, obviously the purpose of this utility model is achieved.
