Abstract
The utility model discloses an LED (Light-Emitting Diode) lamp tube, comprising a lamp tube, a circuit board provided with an LED array, and lamp bases arranged at two ends of the circuit board, wherein the lamp tube is formed by a back shell and a mask; the section of a mask is in an arc-shaped tubular transparent structure; the back shell is in a semi-tube-shaped structure which is matched with the mask to form a circular-tube-shaped lamp tube; the number of the circuit boards is two; and the back surface of the circuit board is provided with radiating fins. For the LED lamp tube, the lamp tube is internally provided with two printed circuit boards which are respectively provided with an LED array; and the radiating fins are arranged between the two printed circuit boards. Therefore, the LED lamp tube not only has large illuminating angle, but also has better radiating condition, and can prolong the service life of the lamp tube.
Description
[technical field]
The utility model relates to the LED technical field, relates to a kind of LED fluorescent tube in particular.
[background technology]
LED is favored by various fields more and more with its plurality of advantages, at lighting field, the LED electricity-saving lamp replaces the position of Halogen lamp LED and fluorescent lamp just gradually.Existing LED energy-saving lamp tube, its structure mainly include the led array in the Transparent lamp tube, fluorescent tube and the lamp socket of lamp tube ends, and led array generally all is arranged on the printed circuit board (PCB).The fluorescent tube of this structure, because of led array only is arranged on printed circuit board (PCB) one side, therefore light angle is restricted, though a side backlight also has light, but obviously than dark many in front, and after working long hours, the temperature of printed circuit board (PCB) and LED lamp pearl will maintain a higher range, cause the printed circuit board (PCB) accelerated ageing, reduce the LED lamp pearl life-span.
[utility model content]
The purpose of this utility model is the deficiency at above-mentioned technology, a kind of LED fluorescent tube is provided, the utility model is provided with two printed circuit board in fluorescent tube, all be provided with led array on this two printed circuit board, and be provided with fin between two printed circuit board, therefore not only light angle is big for the utility model, and the heat radiation situation is better, can prolonging lamp tube service life.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: a kind of LED fluorescent tube, include fluorescent tube, be provided with led array circuit board, be located at the lamp socket at circuit board two ends, it is characterized in that: this fluorescent tube is made of shell on the back and face shield, this face shield is the curved tubulose transparent configuration in cross section, this shell on the back is the semicanal shape structure that fits in the tubular fluorescent tube with face shield, this circuit board is provided with two, is provided with fin at this back of circuit board.
As further specifying of such scheme: two straight flanges of described shell on the back inwardly are provided with boss, and this circuit board is connected on this boss.
Described two back-to-back connections of circuit board.
Described face shield is transparent plastic tube or glass tube.
The beneficial effect that the utility model adopts above technical scheme to reach is:
1. the utility model is provided with two circuit boards, all is provided with led array in the circuit board front, these two back-to-back connections of circuit board, and therefore, lighting angle of the present utility model is comprehensive, the illumination dead angle can not occur.
2. fluorescent tube of the present utility model is made of face shield and shell on the back, the circuit board that is provided with led array can be fixed on the shell on the back, like this without the burden that can alleviate the lamp tube ends lamp socket, also makes the structure of fluorescent tube more firm, even face shield breaks, fluorescent tube still can operate as normal.
3. the utility model is provided with fin at the printed circuit board (PCB) back side, has improved the heat radiation situation of fluorescent tube inside, has reduced the operating temperature of printed circuit board (PCB), has therefore prolonged the life-span of printed circuit board (PCB) and LED lamp pearl.
Therefore 4. fluorescent tube of the present utility model is made of face shield and shell on the back, and face shield is connected on the face shield by groove, and dismounting and easy for installation can be changed the face shield of damage, reduction maintenance cost easily.

Accompanying drawing 1 is a structural representation of the present utility model.
Description of reference numerals: 1, led array; 2, circuit board; 3, face shield; 4, boss; 5, shell on the back; 6, fin.
[specific embodiment]
For further setting forth the utility model 26S Proteasome Structure and Function, the utility model is elaborated below in conjunction with accompanying drawing and preferred embodiment:
As shown in Figure 1, the utility model is a kind of LED fluorescent tube, include the circuit board 2 that fluorescent tube, two be provided with led array 1, the lamp socket that is located at circuit board 2 two ends, all be provided with aluminum alloy heat sink 6 at every circuit board 2 back sides, this two circuit boards 2 are back-to-back to be connected by fin 6.This fluorescent tube is made of shell on the back 5 and face shield 3, this face shield 3 is the glass tube of cross section semicircular in shape, this shell on the back 5 is the semicanal shape structure that fits in the tubular fluorescent tube with face shield 3, two straight flanges of shell on the back 5 inwardly are provided with boss 4, this circuit board 2 is connected on this boss 4, two straight flanges of shell on the back 5 are provided with groove along the radian direction of shell on the back 5, and two straight flanges of this groove and face shield 3 are connected.
Only the part of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
