The invention relates to a light fitting capable of adjusting light source position, which comprises a light reflecting piece and a light source arranged inside the light reflecting piece, wherein the light source comprises a lamp holder and a luminous part; the light fitting further comprises a locating piece; the lamp holder is fixed inside the locating piece; the light reflecting piece is provided with a lamp holder fixing part; and the locating piece is positioned inside the lamp holder fixing part in an adjustable way. The light fitting can simply and reliably adjust the position between the light source and the light reflecting piece, thus reducing the light distribution adjusting time of the light fitting and improving the light distribution adjusting efficiency thereof.
Description
Technical field
The present invention relates to a kind of lighting device, more particularly, relate to the light fixture of a kind of adjustable light sources position.
Background technology
Existing light fixture all comprises reflecting component usually and is arranged on the light source in the reflecting component.The part light that light source sends throws away after the reflecting component reflection, so the relative position of light source and reflective mirror seems particularly important for the luminous intensity distribution of light fixture.At present, the installation site of light source is usually located at the normal place of reflective mirror, for example, the bottom centre of reflective mirror, the relative position between light source and the reflective mirror can not be regulated.In the time need adjusting to the position of light source, adjustment process more complicated and unreliable.
Summary of the invention
The technical problem that the present invention will solve is, to the uncontrollable defective of the light source position of light fixture in the prior art, the light fixture of a kind of adjustable light sources position is provided.
The technical solution adopted for the present invention to solve the technical problems is: the light fixture of constructing a kind of adjustable light sources position; Comprise reflecting component and be arranged on the light source in the said reflecting component; Said light source comprises lamp socket and luminous component; Wherein, said light fixture also comprises keeper, and said lamp socket is fixed in the said keeper; Said reflecting component is provided with the lamp socket standing part, and said reflecting component comprises that first end has the reflector segment of opening, and said lamp socket standing part is tubular, is connected second end of said reflector segment; But be arranged on to said keeper axial adjustment in the said lamp socket standing part;
Said light fixture also comprises dog screw, and said keeper is provided with positioning screw hole, and said lamp socket standing part is provided with elongated slot, and the width of said elongated slot is less than the head width of said dog screw; Said dog screw passes said elongated slot, is connected with said positioning screw hole;
Said keeper is set on the said lamp socket, and said lamp socket is provided with the flange that from said keeper, exposes; Said light fixture also comprises fixed head and the screw that is set in said luminous component, and said screw passes said fixed head and flange, is connected with said keeper.
According to the light fixture of adjustable light sources of the present invention position, said keeper is tubular, and said positioning screw hole is arranged on its sidewall.
According to the light fixture of adjustable light sources of the present invention position, the sidewall of said keeper is provided with breach.
According to the light fixture of adjustable light sources of the present invention position, said elongated slot extends along the axis direction that is parallel to said lamp socket standing part.
The light fixture of the adjustable light sources position of embodiment of the present invention has following beneficial effect: can carry out simply the position between light source and the reflecting component, adjust reliably, reduce the luminous intensity distribution adjustment time of light fixture, improve the luminous intensity distribution adjustment efficient of light fixture.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the sectional view according to the first embodiment of the present invention, light fixture;
Fig. 2 is the structural representation according to the first embodiment of the present invention, reflecting component;
Fig. 3 is the structural representation according to the first embodiment of the present invention, keeper;
Fig. 4 be according to a second embodiment of the present invention, the structural representation of light source.
The specific embodiment
As depicted in figs. 1 and 2, in the first embodiment of the present invention, light fixture 100 comprises reflecting component 101 and is arranged on the light source 104 in the reflecting component 101.This reflecting component 101 comprises reflector segment 102 and lamp socket standing part 103, and wherein reflector segment 102 is revolving bodies of first end opening, like hemispherical, bowl-type etc.Lamp socket standing part 103 is connected second end of reflector segment 102, is communicate with reflector segment 102 cylindric, and the two central shaft is identical.
Embodiments of the invention are not limited thereto, and when adopting light source 104 as shown in Figure 4, lamp socket 105 also can pass through the screw-internal thread fit of external screw thread and keeper 107, and is connected wherein.In addition, keeper 107 can be set in outside the lamp socket 105, and lamp socket 105 directly is fixedly connected with keeper 107 through screw.
As shown in Figure 3, keeper 107 is cylindric, and its end is provided with screw 111, is used for being connected with screw 110.The sidewall of keeper 107 is provided with breach 112, in the time of in keeper 107 is arranged at lamp socket standing part 103, the certain deformation space can be provided.On the sidewall of keeper 107, also be provided with positioning screw hole 113.On the sidewall of lamp socket standing part 103, be provided with corresponding elongated slot 114.Dog screw 115 passes elongated slot 114, is connected with positioning screw hole 113.Elongated slot 114 among Fig. 3 extends along the direction that is parallel to lamp socket standing part 103 axis, and width is less than the width of the head of dog screw 115.
When need turning on dog screw 115 when the axis direction of reflecting component 101 is regulated the position of light source 104, make keeper 107 to move forward and backward.After being adjusted to desirable position, screwed in place screw 115 is clamped at the sidewall of lamp socket standing part 103 between the head and keeper 107 of dog screw 115, makes keeper 107 with respect to lamp socket standing part 103 location.Light source 104 can equal the length of elongated slot 114 along the distance that the axis direction of reflecting component 101 is regulated.
Adopt this structure, can carry out simply the position between light source 104 and the reflecting component 101, adjust reliably, reduce the luminous intensity distribution adjustment time of light fixture, improve the luminous intensity distribution adjustment efficient of light fixture.
