Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are elaborated.
As shown in Figure 1-2, simultaneously see Fig. 3.In a preferred embodiment of the invention, the light source 2 comprising reflector 1 and be fixed in governor motion (not shown), governor motion can drive light source 2 to move forward and backward along the longitudinal axis of reflector 1.Above-mentioned reflector 1 end face and bottom surface opening, the reflective surface that its medial surface is distributed along the circumferential direction of reflector 1 by polylith is spliced to form between two.This reflective surface to have with the longitudinal axis of reflector 1 by least two pieces that the plane of different inclination angle is end to end to be formed, and the angle of plane and longitudinal axis successively decreases along the bottom surface of reflector 1 successively to end face direction.
The reflective mechanism of reflector 1 medial surface is: suppose that medial surface is spliced to form according to above-mentioned rule by M reflective surface, each reflective surface is formed by N number of plane is end to end again, then the light in reflector 1 has been divided into M and has been multiplied by N part, and carries out mixed light; When a certain fragment position under the drive of light source 2 at governor motion on the longitudinal axis of reflector 1 moves, beam angle can change thereupon.Wherein, governor motion belongs to existing known technology, no longer describe, and the shape of reflector 1 lateral surface can design as required at this.In the process regulating beam angle, only use a reflector, therefore enormously simplify the structure of traditional Projecting Lamp.
As shown in Figure 3, further, the bus of above-mentioned reflector 1 is broken line.And this broken line is formed by two line segments are end to end, being respectively the first line segment 101 and the second line segment 102, first line segment 101 length is 53.3-61.3mm, is 46-50 ° with the angle of reflector 1 longitudinal axis; Second line segment 102 length is 151.8-159.8mm, is 29-33 ° with the angle of reflector 1 longitudinal axis.
Preferably, the first line segment 101 is 48 ° with the angle of reflector 1 longitudinal axis, and the second line segment 102 is 31 ° with the angle of reflector 1 longitudinal axis, and the length of getting the first line segment 101 is 57.3mm, and the length of described second line segment is 155.8mm.
Preferably, the medial surface of reflector 1 is spliced to form by the circumferential direction of 10 pieces of reflective surfaces along reflector 1, and the end face opening diameter D of above-mentioned reflector 1 is 340.2mm, and the opening diameter d of bottom surface is 100mm.
The light that light source 2 sends be divide into 20 parts by the reflector 1 then meeting above-mentioned parameter, and its distribution curve flux figure as shown in Figure 4,5.Fig. 4 is that light source 2 moves to from the luminous intensity distribution figure during 35mm of bottom surface, and from figure, now half light intensity angle of Projecting Lamp is 60 °; Fig. 5 is that light source 2 moves to from the luminous intensity distribution figure during 51mm of bottom surface, and from figure, now half light intensity angle of Projecting Lamp is 30 °, therefore by this reflector 1 can realize half light intensity angle from 30 ° to 60 ° continuously adjustabe.
Preferably, in order to improve reflectivity, above-mentioned reflector 1 can by rafifinal rotary press modelling, and rafifinal is a kind of material with high reflectance, and concrete grammar is: first use spinning block spinning, then through sizing die shaping.In addition, in a preferred embodiment of the invention, what light source 2 adopted is 150W ceramic gold-halogen lamp, but it should be noted that the present invention is not only applicable to above-mentioned Metal halogen lamp, and be also applicable to the other light sources of light-emitting area adjoining dimensions, therefore the scope of application is very extensive.
Above embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement accordingly, can not limit the scope of the invention.All equalizations done with the claims in the present invention scope change and modify, and all should belong to the covering scope of the claims in the present invention.
