Fig. 2 is the explosive view of the LED of adjustable spot size.
Fig. 3 is the structural representation of lamp housing main body.
Specific embodiment
In order that technical problem solved by the invention, technical scheme and beneficial effect become more apparent, below in conjunction with
Accompanying drawing and embodiment, the present invention is further illustrated.It should be appreciated that embodiment described herein is used only for explaining this
Invention, is not intended to limit the present invention.
Such as Fig. 1-3, a kind of LED of adjustable spot size of the present invention, including base 1 and lamp housing main body 2, lamp housing main body
2 are connected by support 3 with base 1, and lamp housing main body 2 is the shell-like structure of inner circle foreign side, and the one end open of lamp housing main body 2 and leads to
Cross cover plate 4 to cover, the inside of lamp housing main body 2 is provided with moveable light source emitter, and light source emitter is installed on lamp housing master
The openend of body 2, light source emitter includes COB light source 5, light source radiator 6 and reflector 7, and COB light source 5 is fixed on light source
On radiator 6, reflector 7 is fixed at COB light source 5 by reflector retainer ring 8.
The side plate of lamp housing main body 2 inner side is provided with a bar shaped notch 2-1, and regulating part 9 is provided with notch 2-1, and regulating part 9 is passed through
Notch 2-1 is connected with light source radiator 6, and its excess-three side plate interior sides of lamp housing main body 2 are equipped with bar shaped grooved rail 2-2, with grooved rail 2-2
The side of corresponding light source radiator 6 is equipped with a slotted eye 6-1, is respectively mounted on each slotted eye 6-1 and is provided with steel ball 10, and steel ball 10 is exposed to
