[0039] when the operating knob 97 of the such governor motion 6 of operation is given rotating shaft 95 with rotatory force, this governor motion 6 just passes to light source maintenance seat 3 to the locomotivity that this rotatory force is converted into fore-and-aft direction X through rack and pinion mechanism 96, the light source that has been endowed the locomotivity of fore-and-aft direction X by this transmission keeps seat 3 just to move at the 81 guiding lower edge fore-and-aft direction X of mobile guide mechanism, keeps seat 3 relative position for condenser lens 4 on fore-and-aft direction X thereby regulate light source.When rotating shaft 95 was rotated along direction, light source kept seat 3 to move towards the place ahead and near condenser lens 4 along fore-and-aft direction X; When rotating shaft 95 was rotated along another direction, light source kept seat 3 along fore-and-aft direction X movement towards the rear and away from condenser lens 4.
Lighting device 1 can also comprise shade 101 as shown in Figure 7.Such shade 101 comprises the installation portion 102 that is installed on the lens mount 73 and rotates the shadow shield 104,105,106 and 107 that is attached at freely on the installation portion 102 through hinge 103.Shadow shield 104 is identical with 105 shapes, faces mutually on above-below direction Z; Shadow shield 106 is identical with 107 shapes, faces mutually on transverse direction Y.
Arrive shown in Figure 6 as Fig. 1, light source keeps seat 3 to be installed on the outer cover 5 through governor motion 6, as shown in Figure 8, also can be installed on the outer cover 5 through optical filtering bar 112 without governor motion 6, this optical filtering bar 112 is inserted between condenser lens 4 and the light source 2 at fore-and-aft direction X, and mounting or dismounting maintain freely and absorb or see through optical filter 111 from the part light of light source 2.In this case, outer cover 5 can also comprise the anterior outer cover 113 that lens mount 73 is installed, and this front portion outer cover 113 is attached on the outer cover 5 through governor motion 6a.Support 75 also can be installed on the optical filtering bar 112, rather than is contained on the outer cover 5.Governor motion 6a comprises at the carriage 118 that extends along fore-and-aft direction X between anterior outer cover 113 and the outer cover 5, be formed on the slotted hole 119 that outer cover 5 upper edge fore-and-aft direction X extend and the thumbscrew 120 that is screwed in the fastening usefulness on the anterior outer cover 113 through slotted hole 119, tighten butterfly nut 120 and just anterior outer cover 113 is fixed on the outer cover 5, unscrew butterfly nut 120 and anterior outer cover 113 is in relative to outer cover 5 move freely state along fore-and-aft direction X.Governor motion 6a relies on the anterior outer cover 113 of adjusting to regulate light source maintenance seat 3 with respect to the relative position of condenser lens 4 on fore-and-aft direction X with respect to the movement of the fore-and-aft direction X of outer cover 5.
Optical filtering bar 112 be included in that the front portion is fixed on the outer cover 5 and be fixed at the rear portion light source keep on the seat 3 extend along fore-and-aft direction X, see it is the patchhole 116 on the cylindrical shell 115 of being formed on that the cylindrical shell 115 of rectangle and being used for inserts optical filter 111 from the front.As Fig. 9 and shown in Figure 10, become a plurality of adjacent patchholes 116 at cylindrical shell 115 upper edge fore-and-aft direction X-shapeds, like this, just can suitably use multiple optical filters 111 to carry out diversified illumination performance.
If adopt this routine lighting device 1, owing to comprise light source 2, maintain the light source maintenance seat 3 of light source 2 and the outer cover 5 that light source keeps the tubular of seat 3 be installed, outer cover 5 keeps seat 3 that condenser lens 4 has been installed forwardly with respect to light source, light source keeps seat 3 to comprise light source 2 remained on the light source holder 12 in the recess 11 of front openings and is installed in the multi-disc heat sink 13 of rear and the side of the recess 11 that surrounds light source holder 12 in the light source holder 12, so can dissipate heat from light source 2 effectively with being trapped among multi-disc heat sink 13 around the light source 2, thereby can improve radiating efficiency.
If adopt lighting device 1, because the multi-disc central heat sink plate 43 as multi-disc heat sink 13 is installed on the light source maintenance seat 3 along fore-and-aft direction X extension, form the inside 8 that is communicated with outer cover 5 therefrom and keep the path 10 in the outside, rear 9 of seat 3 with light source, keep the air stream in the outside, rear 9 of seat 3 so in path 10, can form from the inside 8 of outer cover 5 towards light source, thereby improved radiating efficiency.
If adopt lighting device 1, owing to comprise being installed in being used for regulating light source on the outer cover 5 simultaneously and keeping seat 3 with respect to governor motion 6 or the 6a of the relative position of the fore-and-aft direction of condenser lens 4, so keep 3 just can regulate focus from the irradiates light of lighting device 1 aptly with respect to the relative position of the fore-and-aft direction of condenser lens 4 by regulate light source with governor motion 6 or 6a.
If adopt lighting device 1, be used between condenser lens 4 and the light source 2 absorbing or through the optical filter 111 from a part of light of light source 2 owing to be included in to be inserted on the fore-and-aft direction X, just can change color or the pattern of irradiates light so change optical filter 111, thereby carry out various illumination performances.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
