The specific embodiment

With concrete embodiment the present invention is done explanation further below.

See also Fig. 1 and Fig. 2, light fixture 100 of the present invention comprises lamp body 10, is arranged on the lampshade 20 on the lamp body 10 and is arranged on the baffle plate 30 on the lamp body 10.

Please consult Fig. 3 in the lump, lamp body 10 is processed by metal material.This lamp body 10 comprises a base plate 110 and from base plate 110 upwardly extending biside plates 120, also is respectively arranged with end cap 130 and end cap 140 at the two ends of base plate 110.Said base plate 110, side plate 120, end cap 130 and end cap 140 surround a ccontaining cavity jointly.The inside of said ccontaining cavity is used to be provided with light source 112 like light emitting diode or laser diode.In the present embodiment, said base plate 110 is provided with support column 111 and is used for supporting printing board 113,112 of light sources be arranged on printed circuit board (PCB) 113 with support column 111 opposite surfaces.Said side plate 120 edges are away from being formed with connecting portion 121, location division 122 and flanging 123 on the direction of base plate 110 successively.Formation one is about the angle of 120 degree between said connecting portion 121 and the base plate 110.Said location division 122 is arranged on the side away from base plate 110 of connecting portion 121.Location division 122 is provided with perpendicular to base plate 110.Said location division 122 is provided with one and radially extends and inwardly protruded convex epirelief 124 along lamp body 10.Said convex epirelief 124 can be by the 122 inwardly extruding and forming from the location division.122 the position near end cap 130 is provided with second perforate 125 in the location division, and described second perforate 125 is used to be provided with baffle plate 30, forms pivotal connection thereby make between baffle plate 30 and the lamp body 10.Said flanging 123 is arranged on the edge of side plate 120, thereby its self-align 122 extends internally and base plate 110 parallels.Said flanging 123 and the said convex epirelief 124 common sliding trays 126 that form, this sliding tray 126 is used for ccontaining lampshade 20.End cap 140 is fixedly connected with side plate 120 with base plate 110.End cap 130 forms dismountable the connection with base plate 110 with side plate 120.Said end cap 130 is provided with flanging 131 for roughly being trapezoidal around the end cap 130, and flanging 131 is provided with installing hole 132 makes end cap 130 be fixed in the two ends of light fixture.And, on end cap 130, also be provided with a plurality of through holes 133, thereby the inside that this through hole 133 is used for power line is introduced into lamp body 10 from the external world is light source power supply.

Said lampshade 20 is arranged on the sliding tray 126 that is formed jointly by flanging 123 and convex epirelief 124.In light fixture 100 assemblings, lampshade 20 can be inserted among the sliding tray 126 from the side.The manufacturing materials of lampshade 20 be selected from glass, Merlon (PC) and polyethylene acrylic acid methyl esters (PMMA) one of them.

See also Fig. 4, said baffle plate 30 comprises fixed part 31 and catch 32, said fixed part 31 comprise top 33 and from the top 33 to the both sides that extend below 34.Catch 32 is connected with top 33 and is arranged between the both sides 34.Described both sides 34 are respectively arranged with first perforate 35.When baffle plate 30 is arranged on 10 last times of lamp body, the position of first perforate 35 and second perforate 125 will be overlapped, thereby a fixture 36 is passed this first perforate 35 and this second perforate 125 and made between baffle plate 30 and the lamp body 10 and form pivotal connection.

Light fixture 100 of the present invention can assemble lamp body 10 and baffle plate 30 when assembling in advance.Then baffle plate 30 edges are passed the rotating shaft rotation of first perforate 35 and second perforate 125, thereby manifested the position of sliding tray 126.Lampshade 20 is plugged from the side to lamp body 10.Thereby make the catch 32 in the baffle plate 30 cover said lampshade 20 baffle plate 30 counter-rotation at last, thereby utilize catch 32 that lampshade 20 is fixed on the sliding tray 126.When lampshade 20 need be dismantled or change because of various reasons, also only need earlier baffle plate 30 to be raised, then lampshade 20 side direction are pulled out the process that can accomplish dismounting.Therefore, the structure of light fixture 100 of the present invention becomes simply the dismounting of lampshade 20 and assembling, helps saving cost.In addition, owing to lamp body 10 inner sliding trays 126 are formed by flanging 123 and convex epirelief 124 jointly.Can accomplish because the formation of convex epirelief 124 only need be carried out inside punching press to side plate 120, so the making of this sliding tray 126 is also comparatively simple.Above-mentioned sliding tray 126 can be accomplished on same metallic plate by simple technology, and need side plate 120 repeatedly not bent or fin and form sliding tray 126 on side plate 120 interior welds.

As required, baffle plate of the present invention is not limited to above-mentioned embodiment.See also Fig. 5, be another embodiment of baffle plate of the present invention.This baffle plate 40 comprises fixed part 41 and catch 42, said fixed part 41 comprise top 43 and from the top 43 to the both sides that extend below 44.Catch 42 is connected with top 43 and is arranged between the both sides 44.Different with first embodiment is, 44 inboard is provided with inwardly outstanding lug boss 46 in both sides, and this lug boss 46 can be arranged in second perforate 125 of lamp body 10, forms pivotal connection thereby make between baffle plate 40 and the lamp body 10.At this moment, baffle plate 40 is fixed on the lamp body 10, and does not need retaining elements such as screw through the resilient force between both sides 44 and the top 43.In addition; Can also be provided with outstanding clamping part (figure does not show) on the said catch 42; End cap 130 is provided with corresponding draw-in groove (figure does not show) simultaneously; When baffle plate 40 turns to the position of blocking lampshade 20, thereby this clamping part also is fixed on the lamp body 10 baffle plate 40 among can correspondingly snapping in draw-in groove.When needs are dismantled, clamping part is pushed away draw-in groove can raise baffle plate 40.

Be noted that above-mentioned embodiment is merely preferred embodiments of the present invention, those skilled in the art also can do other variation in spirit of the present invention.These all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
