The specific embodiment
Below in conjunction with accompanying drawing utility model is further described.
As shown in Figure 1, a kind of adjustable angle LED annular light source device comprises hollow sleeve 1, upper end cover 2, ring flange 5, stay bolt 6, trapezoidal reflector 7 and bottom end cover 8.Bottom end cover 8 is the circular ring type cavity structure, and periphery is provided with step, is used to prop up an end of trapezoidal reflector 7, and middle cavity is used for 9 illuminations (as Fig. 2) of LED lamp.Be provided with cavity in the middle of the ring flange 5, be used for socket hollow sleeve 1, periphery can evenly be installed the connection revolute pair (as shown in Figure 3) of trapezoidal reflector 7.As shown in Figure 4, upper end cover 2 middle parts are provided with the cylinder of projection, and cylinder is provided with perforate, and the cylinder lower end is a circular slab, circular slab is provided with the perforate that stay bolt 6 can be set, and the size of circular slab is corresponding with the projected area that a plurality of trapezoidal reflectors 7 splicing backs form pyramidal structure; The circular slab lower end is the curved surface reflective surface, is used to reflect the light that LED lamp 9 sends.As shown in Figure 5, trapezoidal reflector 7 is preferred tapered radial, is convenient to a plurality of trapezoidal reflectors 7 splicings and is conical; Be furnished with LED lamp 9 on the plate face of trapezoidal reflector 7, some LED lamps 9 can circularize layout on the spliced trapezoidal reflector 7, can make a plurality of LED lamps 9 be arranged to the nested structure of a plurality of annulars, a plurality of LED lamps 9 provide power supply by circuit board 10, and circuit board 10 can be arranged on the trapezoidal reflector 7; Trapezoidal reflector 7 is preferably 6.Hollow sleeve 1 is a cylindrical shape as shown in Figure 6, and diverse location is provided with a plurality of screwed holes on the hollow sleeve 1.
