Description

A kind of light-emitting diode light bar

Technical field

The present invention relates to technical field of lighting fixtures, is a kind of LED illumination lamp bar more specifically.

Background technology

LED is the abbreviation of English light emitting diode (light emitting diode); LED is a kind of semiconductor that can electric energy be converted into visible light; It changed the incandescent lamp tungsten filament luminous with energy-saving fluorescent lamp tricolor powder principle of luminosity, and adopt electric energy luminous, have long, numerous advantages such as light efficiency is high, radiationless, low-power consumption of life-span; Along with the energy-conservation and proposition green illumination theory, LED is introduced in the lighting as light source gradually.

At present, in numerous LED illuminating products, LED lamp bar relies on that it is low in energy consumption, the life-span long, easy for installation, advantage such as volume is little; Be widely used in places such as market, hotel, exhibition room, outdoor decoration, still, LED lamp bar interface in the market all is to interconnect with fixed terminal; Such structure than higher, just needs terminal all to be on the same horizontal line, if indivedual terminal occurs tilting to the requirement of installing; The lamp bar of back then can not normal mounting so; In case also have certain lamp bar of being exactly fault to occur,, can only disassemble one by one by outmost lamp bar from both sides owing to connect closely between the fixed terminal; Up to tearing out of order lamp bar position open, so just bring very big difficulty to maintenance.

Summary of the invention

In order to overcome above present difficulty, the invention provides a kind of rational in infrastructure, assembling LED lamp bar simple, easy to maintenance.

The present invention takes following technical scheme to realize: a kind of LED lamp bar, comprise lampshade, radiator, LED, light source board, terminal and end cap, and said LED is fixed on the said light source board; And be placed on the inside of said radiator; The open upper end of said radiator, said lampshade is placed on the top of said radiator, and opening part is sealed; Said end cap is placed on the two ends of said radiator; The bottom surface of said radiator is provided with several grooves, and it is outside that the electric wire of said light source board both sides extends to said radiator through said groove, stretches out on the outside electric wire of said radiator to be connected with terminal.

The present invention can also take following technical scheme to realize:

Also comprise the line sheath, said line sheath outline is similar with said groove shape, is provided with annular groove around it, and the centre is provided with through hole, and said line sheath is installed in the said groove, and said annular groove and said radiator closely cooperate;

Also comprise the location buckle, said locator card is buckled and is provided with screw hole, and said locator card is buckled and also is provided with kink and projection; Said radiator bottom surface is provided with groove; The side is provided with recess, and said kink and said groove match, and said projection and said recess match.

Advantage of the present invention and beneficial effect are embodied in the following aspects:

The 1 fixed terminal connection with lamp bar junction becomes being flexible coupling of terminal, has simplified the installation, maintenance program of lamp bar so greatly, has reduced the installation, maintenance difficulty, makes product have more practicality.

The locator card buckle structure of 2 uniquenesses, the present invention is very convenient for feasible installation, dismounting.

3 increase the line sheath, avoid damaging owing to the friction of electric wire and radiator groove the exocuticle of electric wire, cause potential safety hazard.

The specific embodiment

Below in conjunction with accompanying drawing 1-5 the embodiment of the invention is done further detailed description:

The 1st, LED, the 2nd, lampshade, the 3rd, radiator, the 4th, light source board, the 5th, projection, the 6th, location buckle; The 7th, kink, the 8th, groove, the 9th, line sheath, the 10th, screw, the 11st, through hole, the 12nd, electric wire; The 13rd, groove, the 14th, recess, the 15th, end cap, the 16th, terminal, the 17th, screw hole, the 18th, annular groove.

The present invention includes lampshade 2, radiator 3, LED1, light source board 4, line sheath 9, terminal 16 and end cap 15; Wherein LED1 is fixed on the light source board 4, and is placed on the inside of radiator 3, the open upper end of radiator 3; Lampshade 2 is placed on the top of radiator 3; And opening part sealed, end cap 15 is placed on the two ends of radiator 3, and lampshade 2 and radiator 3 are covered.

The bottom surface of radiator 3 is provided with two grooves 8, and the outline of line sheath 9 is similar with the shape of groove 8, is provided with annular groove 18 around it; The centre is provided with through hole 11, and line sheath 9 is installed in the groove 8, makes annular groove 18 and radiator 3 closely cooperate; The electric wire 12 of light source board 4 extends to the outside of radiator 3 through through hole 11; Stretch out on the outside electric wire 12 of radiator 3 splicing ear 16 respectively, be flexible coupling through terminal 16 between two adjacent lamp bars, like this install, lamp bar of dismounting separately just in the dismounting; And do not influence other lamp bars, simplified the program of installation, maintenance greatly.

The present invention also need locate buckle 6 when mounted; Location buckle 6 is provided with screw hole 17, also is provided with kink 7 and projection 5 on the buckle 6 of location, and radiator 3 bottom surfaces are provided with groove 13; The side is provided with recess 14; Kink 7 matches with groove 13, and projection 5 matches with recess 14, thereby with location buckle 6 the lamp bar is fixed.

Assembling process of the present invention is: at first line sheath 9 is fixed on the groove 8 of radiator 3, then electric wire 12 is passed the through hole 11 of line sheath 9, then an end of two wires 12 is loaded onto terminal 16 respectively; Then LED1 is fixed on the light source board 4, again light source board 4 is put in the radiator 3, then electric wire 12 is welded on the light source board 4; Then lampshade 2 is inserted radiator 3, then end cap 15 is installed in the both sides of lamp bar, will locate buckle 6 with screw 10 then and fix on the wall; Then the lamp bar is put in the buckle 6 of location; And making kink 7 and groove 13 match, projection 5 matches with recess 14, has so just accomplished assembling of the present invention.

Utilize technical scheme of the present invention, or those skilled in the art designing the similar techniques scheme under the inspiration of technical scheme of the present invention, and reach above-mentioned technique effect, all is to fall into protection scope of the present invention.
