Abstract

The utility model provides a Light-Emitting Diode (LED) lamp tube and mainly relates to the field of floodlight manufacturing, in particular to the field of lamp tube manufacturing. The LED lamp tube comprises an LED lamp, a circuit board, an outer support and an outer cover. The outer cover is fixed through the outer support, a U-shaped groove surface is formed in the outer support and a reflection cover is arranged on the U-shaped groove surface of the outer support. The cross section of the reflection cover is in an inverted trapezoid shape without a lower side, the bottom face of the reflection cover is a plane, and the reflection cover attaches to the surface of the circuit board and the side face of the U-shaped groove. The circuit board and the LED lamp attach to the inner surface of the outer support. The reflection cover is fixed through the outer support and the outer cover or directly fixed through the outer support, an open hole which is capable of enabling the LED lighting to emit outwards is formed in the reflection cover and corresponds to the LED lamp, and the reflection cover is directly and integrally formed through injection molding. Compared with the existing LED lamp tube, the reflection cover which is arranged in the outer support can strengthen specular reflection of the LED lighting by 30 percent, and the LED lamp tube has the advantages of increasing the angle of the lighting which emits out of the outer cover and strengthening emitted brightness of the lighting.

Background technology

Compared to traditional fluorescent lamp, more environmental protection of LED fluorescent tube, energy-conservation and the life-span is longer, thereby the LED fluorescent tube has developed into illuminations commonly used in people's life gradually.Because the volume of LED is very little, the brightness of illumination that can produce is less, and present LED fluorescent tube all needs could produce the brightness of illumination that may replace conventional fluorescent, thereby improve the LED lighting tube brightness with a plurality of LED combinations, improves its practicality and seems unusually important.And general LED fluorescent tube directly is to be mapped to by the LED lamp to transmit on the outer cover outside the fluorescent tube again, and the beam projecting angle is little, and brightness is not high enough.

Summary of the invention

For improving the brightness of present LED fluorescent tube, the increasing light angle of emergence, the utility model provides a kind of LED fluorescent tube of high brightness.

The technical scheme that the utility model adopts is:

A kind of LED fluorescent tube, mainly comprise the LED lamp, wiring board, support arm and outer cover, outer cover is fixed by support arm, wiring board and LED lamp invest the support arm inner surface, the U-lag face is arranged in the support arm, along the U-lag face in the support arm reflection shield is set, the cross section of reflection shield is not descend the handstand of the length of side trapezoidal, the bottom surface is the plane, reflection shield invests wiring board and LED lamp surface, reflection shield is by support arm and outer cover or directly fixed by support arm, and corresponding LED lamp is provided with the perforate that the transmission of LED light is gone out on the reflection shield, and being shaped as of reflection shield perforate can make the LED lamp wiring tubaeform with what be shot out than wide-angle.Reflection shield extends along the support arm direction directly by injection mo(u)lding, is connected as a single entity.Described reflection shield is fixed in the LED fluorescent tube by outer cover and support arm, support arm is provided with draw-in groove, outer cover is fixed by the draw-in groove that inserts on the support arm, and reflection shield is being pressed in the outer cover below, and reflection shield is close on the wiring board and U-lag side on the U-lag bottom surface in the support arm.Described reflection shield directly is fixed in the LED fluorescent tube by support arm, and the U-lag face top in the support arm inwardly is provided with the holder that is parallel to the reflection shield bottom surface, and holder is pushed down reflection shield, so that reflection shield can be fixed in the LED fluorescent tube.The cross section of described reflection shield is not descend the handstand of the length of side trapezoidal, and the bottom surface is the plane.Described reflection shield extends along the support arm direction directly by injection mo(u)lding, is connected as a single entity.Being shaped as of described reflection shield perforate can make the LED lamp wiring tubaeform with what be shot out than wide-angle.

Compared with prior art, the advantage that the utlity model has is:

The reflection shield that arranges in support arm can strengthen the border face reflection of 30% LED light, strengthened the brightness that light penetrates, and has increased the angle that light penetrates outer cover, makes illumination zone wider, thereby improves the illumination performance of LED fluorescent tube.
