Abstract

The utility model discloses a light-emitting diode (LED) lamp bar allowing two faces to emit light and belongs to the field of application of LED lighting lamps. The LED lamp bar mainly comprises a first printed circuit board (PCB), a second PCB, LED light sources and resistors, wherein the LED light sources and the resistors are arranged on the first PCB and the second PCB. The LED lamp bar further comprises a PC cover, a plug, a male connector and a female connector. The first PCB and the second PCB are superposed at an interval in a back-to-back mode, one end of the first PCB and one end of the second PCB are electrically connected and fixed through a pin header, the other end of the first PCB is connected with the male connector through a lead, and the other end of the second PCB is connected with the female connector through a lead. According to the LED lamp bar, two faces of the LED lamp bar can emit light, therefore, the illumination angle is enlarged, cooling effect is strengthened, and service life is prolonged.

Description

Double-side LED lamp bar
Technical field
The utility model relates to LED lighting application, relates in particular to a kind of double-side LED lamp bar.
Background technology
Because LED has life-span length, high brightness, low energy consumption, highly significant aspect the saving energy, therefore it is applied to the light emitting source of LED lighting in a large number, such as the light emitting source of the light fixtures such as LED bulb lamp, LED fluorescent lamp, LED flexible light band and LED straight strap lamp that occur in the market, is all to consist of LED.Especially LED straight strap lamp because its light is soft, the life-span is long etc., and advantage is widely used the every field in the middle of life and industry, particularly in places such as advertisement and identifier illumination, bus-stop, home decoration illuminations.
Yet common LED lamp bar is all generally that one side is luminous in the market, only at light fixture, be simultaneously provided with the pcb board of LED light source, because one side is luminous, limited lighting angle, cause decorative effect to reduce.
Summary of the invention
In order to solve above-mentioned existing technical deficiency and defect, the utility model provides a kind of LED lamp bar of double-side.
The purpose of this utility model is achieved by the following technical solution:
A double-side LED lamp bar, comprises the first pcb board, the second pcb board, and is provided with LED light source and resistance on the first pcb board and the second pcb board; Also comprise PC cover, plug, public connector and female connector; The first pcb board and the second pcb board are arranged in the U-shaped draw-in groove of PC cover and lean against privately and place, and the first pcb board and the second pcb board are not installed the mutual mapping of one side of LED light source, and the first pcb board and the second pcb board at one end conduct electricity and are connected and fix with arranging pin; The other end, wherein the first pcb board connects public connector by wire, and the second pcb board connects female connector by wire.
As optimal technical scheme of the present utility model, described public connector is mutually to mate design with female connector.
As optimal technical scheme of the present utility model, described PC cover is tubular type, along PC cover shell, the first circle hole groove and the second circle hole groove is longitudinally set, and described the first circle hole groove and the second circle hole groove are longitudinally equally divided into two halves by PC cover symmetrically.
As optimal technical scheme of the present utility model, at described PC cover inwall, be vertically arranged with two pairs of U-shaped draw-in grooves.
As optimal technical scheme of the present utility model, the plane at the plane at described the first pcb board place and the second pcb board place is parallel to each other.
Compared with prior art, the beneficial effect the utlity model has is: realize double-side, increased lighting angle; Production technology is simple, can greatly improve production efficiency, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the floor map of a kind of embodiment of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B section of Fig. 1 and the stereogram that is connected with public connector.
Description of reference numerals: 1, LED light source; 21, the first pcb board; 22, the second pcb board; 3, PC cover; 4, plug; 5, female connector; 6, public connector; 7, U-shaped draw-in groove; 81, the first circle hole groove; 82, the second circle hole groove.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Shown in accompanying drawing 1 to 3, a kind of double-side LED lamp bar, comprises the first pcb board 21, the second pcb board 22, and is provided with LED light source 1 and resistance on the first pcb board 21 and the second pcb board 22; Also comprise PC cover 3, plug 4, female connector 5 and public connector 6; The first pcb board 21 and the second pcb board 22 are arranged in the U-shaped draw-in groove 7 of PC cover 3 and lean against privately and place, the first pcb board 21 and the second pcb board 22 are not installed the mutual mapping of one side of LED light source 1, and the first pcb board 21 is at one end connected by row's pin conduction with the second pcb board 22 and is fixing; The other end, wherein the first pcb board 21 connects public connector 6, the second pcb boards 22 by wire and connects female connector 5 by wire.
Public connector 6 is mutually to mate design with female connector 5, makes adjacent double-side LED lamp bar can facilitate connected in series.
PC cover 3 is tubular type, along PC cover shell, the first circle hole groove 81 and the second circle hole groove 82 is longitudinally set, and described the first circle hole groove 81 and the second circle hole groove 82 are longitudinally equally divided into two halves by PC cover 3 symmetrically.
At PC, cover 3 inwalls and be vertically arranged with two pairs of U-shaped draw-in grooves 7.
The placement that is parallel to each other of the first pcb board 21 and the second pcb board 22.
In the utility model, at two pcb boards, be parallel to each other and back-to-back stack setting, and be connected and fixed by row's pin conduction.On the one hand, realize double-side, increased lighting angle; On the other hand pcb board is had to certain spacing distance each other, the heat producing while guaranteeing the work of LED lamp bar outwards distributes rapidly, increases radiating effect, thereby increases the service life; This technique is simple, can greatly improve production efficiency, reduces production costs.From integral body, the LED lamp bar that this lamp bar is a kind of water proof and dust proof.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
