Technical field
The invention belongs to the video display lighting engineering, particularly a kind of light source controlling mechanism that is applicable to the reflection concentration type light fixture.
Background technology
General spotlight light source foam is contained on the lamp socket, is vertically mounted on simultaneously on the base with reflector, can move simultaneously, also can independent mobile lamp socket, adjust focal length, and realize the spot diameter that is fit to.The foam of reflector spotlight is mounted in the reflector centre bore, the mobile change spot diameter size of illuminator.Since adopt parabolic reflector, very responsive to the change in location of light source, but therefore need provide a kind of light source mechanism of fine adjustment rational in infrastructure to satisfy the performance needs.
Summary of the invention
The object of the present invention is to provide a kind of light source controlling mechanism, it is to be installed on the whole bonnet, according to different lamp bodies, changing the bonnet profile can be combined integrated with reflector spotlight, and can regulate lamp socket in front and back, realize adjusting focal length, change beam angle width, the spot size that obtains being fit to.
The objective of the invention is to be realized by following technical scheme: it is to be screwed onto together by back circle, bonnet, back shroud, and the location-plate two ends are provided with two symmetry axis trepannings, and two axle sleeves are inserted in respectively in the respective aperture, and are integrally welded; Two locating shafts pass corresponding axle sleeve respectively, and terminal and back shroud is spirally connected, and spring is through on the locating shaft, is stuck in the axle sleeve port position; Lamp socket is screwed onto two lamp socket hole sites on the location-plate, and three symmetrical holes of positioning sleeve one end are corresponding one by one with three symmetry location trepannings at location-plate center, are screwed; Positioning sleeve is provided with internal thread hole, be connected with adjusting knob screw rod threaded one end, the adjusting knob screw rod other end passes back shroud, link to each other with the adjusting knob in the back shroud outside, be provided with a hole in the bonnet relevant position, so just can regulate adjusting knob in the bonnet outside, make the rotation of adjusting knob screw rod, be convenient to regulate lamp socket front and back displacement.
Described bonnet lateral surface installs a handle.
Described axle sleeve endoporus is a unthreaded hole, is slidingly connected with locating shaft.
Described adjusting knob screw rod, positioning sleeve and lamp socket are coaxial.
Reflector is fixed on the reflector support, is connected on the base; Bulb is cylindrical, and an end inserts lamp socket, and the other end is installed in the reflector centre bore, can move on the light center axle reposefully, adjusts beam angle width, adjusts spot size, satisfies the performance needs.
Described bonnet can be circle, ellipse, square or rectangle etc., decides on the lamp body of combination with it is different.
Advantage of the present invention is:
But 1 integral installation is convenient and swift on the reflection concentration type light fixture of any adaptation, the focusing exactly.
2, the reflector spotlight light source controlling mechanism is that bulb is located in the reflector centre bore, carries out reflective optical system design by light source center, efficiency of light energy utilization height, and light quality is even, the illumination height.
3, this kind light source controlling mechanism design, easy for installation, rationally, be fit to be installed in reflector spotlight the Lights section.

The specific embodiment
The described a kind of light source controlling mechanism of present embodiment, as Fig. 1, Fig. 3, shown in Figure 4, it is to be screwed onto together by back circle 10, bonnet 1, back shroud 7, location-plate 2 two ends are provided with two symmetry axis trepannings, 16, two axle sleeves 9 and are inserted in respectively in the respective aperture, and are integrally welded, two locating shafts 3 pass corresponding axle sleeve 9 respectively, terminal and back shroud 7 is spirally connected, and spring 8 is through on the locating shaft 3, is stuck in axle sleeve 9 port position; Lamp socket 14 is screwed onto 17 positions, two lamp socket holes on the location-plate 2, and three symmetrical holes of positioning sleeve 6 one ends are corresponding one by one with three symmetry location trepannings 18 at location-plate 2 centers, are screwed; Positioning sleeve 6 is provided with internal thread hole, be connected with adjusting knob screw rod 4 threaded one ends, adjusting knob screw rod 4 other ends pass back shroud 7, link to each other with the adjusting knob in back shroud 7 outsides, be provided with a hole in bonnet 1 relevant position, so just can regulate adjusting knob in bonnet 1 outside, make 4 rotations of adjusting knob screw rod, be convenient to regulate lamp socket 14 front and back displacements.
Described bonnet 1 lateral surface installs a handle 5.
Described axle sleeve 9 endoporus are unthreaded hole, are slidingly connected with locating shaft 3.
Described adjusting knob screw rod 4, positioning sleeve 6 and lamp socket 14 are coaxial.
Described bonnet 1 can be circle, ellipse, square or rectangle etc., decides on the lamp body of combination with it is different.Bonnet 1 in the present embodiment is circular.
As shown in Figure 2, two aluminium section bar lamp body side plates 15 are inserted back circle 10 and symmetrical with it preceding circle, with whole light fixture of the affixed one-tenth of screw.This kind light source controlling mechanism, but integral installation is convenient and swift on the reflection concentration type light fixture of any adaptation, the focusing exactly.
