Description
Technical field
This utility model relates to light-control technology field, is specially a kind of diaphragm.
Background technology
Diaphragm is in many applications, some places are except requiring to provide illumination functions, and the light spot shape and size to light fixture output has particular/special requirement, but do not have in the market not only to change light spot shape but also the device of spot size can be regulated easily, to this end, it is proposed that a kind of diaphragm.
Utility model content
The purpose of this utility model is to provide a kind of diaphragm, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，This utility model following technical scheme of offer: a kind of diaphragm，Including connecting cylinder and housing，The left end of described housing is provided with light inlet，And the middle part of housing is provided with slot，Reflector and brake sack it is provided with in slot，And brake sack is positioned at the top of reflector，And the upper center of housing is provided with light-emitting window，The front end of described light inlet is sequentially installed with dustproof glass、Reflector、Light source bracket、COB light source and radiator，And described COB light source is fixing on a heat sink by light source bracket，Reflector and dustproof glass are fixed with light inlet thread by radiator，COB light source is connected with power supply by wire，Equipped with the first convex lens bottom described light-emitting window，Described connecting cylinder is socketed with the lower end of light-emitting window，Connecting cylinder is connected with the lower end of inner core by screw thread，And the second convex lens is installed on the top of inner core.
Preferably, described reflector is 45 ° with the angle of housing bottom.
Preferably, described reflector is a kind of aluminium plated surface reflecting mirror.
Preferably, described reflector is provided with hollow out in the middle of brake sack, and brake sack and is shaped as square, ellipse, hexagon or star, and brake sack fits tightly with reflector.
Preferably, the first convex lens at described light-emitting window forms battery of lens, by precession or the back-out of inner core screw thread, thus it is possible to vary the distance between the first convex lens and the second convex lens with second convex lens on the top of inner core.
Compared with prior art, the beneficial effects of the utility model are: this diaphragm both can control light spot shape, can control again spot size, may be used for the illumination place requiring light spot shape and size, and simple in construction is easy to use.
Accompanying drawing explanation
Fig. 1 is this utility model shell structure schematic diagram；
Fig. 2 is this utility model structural representation.
In figure: 1 radiator, 2COB light source, 3 light source brackets, 4 reflectors, 5 dustproof glass, 6 light inlets, 7 brake sacks, 8 reflectors, 9 first convex lenss, 10 connecting cylinders, 11 inner cores, 12 second convex lenss, 13 housings, 14 light-emitting windows.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2，A kind of technical scheme of this utility model offer: a kind of diaphragm，Including connecting cylinder 10 and housing 13，The left end of housing 13 is provided with light inlet 6，And the middle part of housing 13 is provided with slot，Reflector 8 and brake sack 7 it is provided with in slot，Reflector 8 is a kind of aluminium plated surface reflecting mirror，Angle bottom reflector 8 and housing 13 is 45 °，Brake sack 7 is installed on reflector 8，And the middle hollow out of brake sack 7 is shaped as square、Oval、Hexagon or star，And brake sack 7 fits tightly with reflector 8，And brake sack 7 is positioned at the top of reflector 8，And the upper center of housing 13 is provided with light-emitting window 14，The first convex lens 9 at light-emitting window 14 forms battery of lens with second convex lens 12 on the top of inner core 11，By precession or the back-out of inner core screw thread，The distance between the first convex lens 9 and the second convex lens 12 can be changed，The front end of light inlet 6 is sequentially installed with dustproof glass 5、Reflector 4、Light source bracket 3、COB light source 2 and radiator 1，And COB light source 2 is fixed on radiator 1 by light source bracket 3，Reflector 4 and dustproof glass 5 are fixed with light inlet 6 thread by radiator 1，COB light source 2 is connected with power supply by wire，Equipped with the first convex lens 9 bottom light-emitting window 14，Connecting cylinder 10 is socketed with the lower end of light-emitting window 14，Connecting cylinder 10 is connected with the lower end of inner core 11 by screw thread，And the second convex lens 12 is installed on the top of inner core 11，The light come in by light inlet 6，After brake sack 7，The light being only irradiated to brake sack 7 openwork part can be reflected by reflector 8，Other some light are absorbed，So can be obtained by the hot spot identical with brake sack 7 openwork part shape，Just can reach to change the purpose of light spot shape by the shape changing brake sack 7 openwork part；According to the image-forming principle of convex lens, will become big or diminish according to the first convex lens 9 battery of lens and the change of the distance of the second convex lens 12 from the size of light-emitting window 14 hot spot out, thus reach to regulate the purpose of spot size.Reflector 8 sophistication high precision sputtered aluminum film, life of product is long, and antioxidation, free of pinholes, fineness good, high reflectance, reduces the loss of light.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
