The light fixture that a kind of lamp holder position is adjustable

Technical field

The utility model relates to a kind of light fixture, the adjustable light fixture of particularly a kind of lamp holder position.

Background technology

At present, the installation of lamp socket all is fixed structures in the existing light fixture, when a light fixture uses the bulb of different capacity or kind, because of the big or small length difference of bulb, the central point of light source will just can not make the luminous point of every kind of different bulb all focus on the same point at diverse location so.For example: the light fixture of 50W and 100W may will satisfy luminous point with different lamp casings and focus on requirement or appearance requirement.

Summary of the invention

The utility model has overcome the shortcoming that the light fixture lamp socket can not be regulated in the prior art, provides a kind of lamp holder position adjustable light fixture.

In order to achieve the above object, the adjustable light fixture of a kind of lamp holder position of the present utility model, be provided with lamp socket, housing, described lamp socket is fixed on the adjustment seat, adjustment seat is inserted in the adjustment hole on the housing, between form and be slidingly matched, at described adjustment seat lower end secured adjusted frame, offer vertical bar shaped pilot hole on adjusting bracket, adjustment screw is passed described pilot hole secured adjusted frame.

The light fixture that lamp holder position of the present utility model is adjustable, after adjustment screw is unscrewed, can move up and down adjusting bracket and adjustment seat, make lamp socket be positioned at correct position, tighten adjustment screw so again, fixed lamp-socket so just can be easily be in the center of light fixture or the position that needs with the light source of different capacity or kind, makes light fixture can produce best light distribution effect.

Description of drawings

Schematic diagram cutd open in the office of light fixture when Fig. 1 represented among the embodiment of the present utility model lamp socket heightened;

Schematic diagram cutd open in the office of light fixture when Fig. 2 represented among the embodiment of the present utility model lamp socket turned down.

The specific embodiment

With reference to accompanying drawing, will be described in detail the specific embodiment of the present utility model.

Referring to Fig. 1, figure cutd open in the office of light fixture when Fig. 2, Fig. 1 illustrated present embodiment lamp socket is heightened; Fig. 2 illustrates present embodiment when lamp socket is turned down, and figure cuts open in the office of light fixture; The light fixture that the lamp holder position of present embodiment is adjustable, be provided with lamp socket 5, under reaching, the lamp socket outside can be provided with housing, described lamp socket 5 can be existing all kinds of lamp socket, on lamp socket 5, all kinds of lamps can be installed, certainly, on lamp socket, also to connect power line etc., described lamp socket 5 is fixed on the adjustment seat 4, adjustment seat 4 is inserted in the adjustment hole 7 on the housings, between form and be slidingly matched, at described adjustment seat 4 lower end secured adjusted framves 1, offer vertical bar shaped pilot hole 8 on adjusting bracket 1, adjustment screw 6 can secured adjusted frame 1 by described pilot hole 8.

After adjustment screw 6 is unscrewed, can move up and down adjusting bracket 1 and adjustment seat 4, make lamp socket 5 be positioned at correct position, tighten adjustment screw 6 so again, fixed lamp-socket 5, so just can be easily the light source of different capacity or kind be in the center of light fixture or the position that needs, makes light fixture can produce best light distribution effect.

Described adjustment hole 7 can be arranged on the housing of lamp socket bottom, and the length of the face that is slidingly matched between adjustment seat 4 and the adjustment hole 7 is adjustable length.This face of being slidingly matched can pass through as Fig. 1, mode shown in Figure 2 realizes, that is: adjustment seat 4 is cylinders that certain altitude is arranged, and adjustment hole 7 also is the cylindrical hole that corresponding height is arranged, at this moment, the flanging 41 of outside bending can be set in adjustment seat upper end, prevent adjustment seat 4 by adjustment hole 7 from following dial-out; Adjustment seat 4 also can be shorter, and adjustment hole 7 is longer, and adjustment seat 4 is slided in adjustment hole 7; Certainly, adjustment hole 7 also can be shorter, and adjustment seat 4 is longer.
