Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, two circles of spring retainer rotate focusing Ceiling light, comprise housing 1, light source 2, radiator 3, protecgulum and convex lens 5, described light source 2 is fixed on described radiator 3, and be positioned at described housing 1, described housing 1 is fixed on radiator 3, and described convex lens 5 are fixed on described protecgulum, and described protecgulum is connected with described housing 1;
As shown in Figure 1 and Figure 2, described protecgulum comprises the rotating ring 41 of circulus, loose collar 42 and retaining spring 43; The outside of described rotating ring 41 is provided with annular groove 44, and described housing 1 is provided with and stretches into described annular groove 44 and limit described rotating ring 41 and can only do the position limiting structure of relative rotary motion with described housing 1;
As shown in Figure 1, described rotating ring 41 is provided with array female thread structure; Described loose collar 42 is placed in inside described rotating ring 41, is provided with the salient point 46 that several and described internal thread matches; Described loose collar 42 is provided with several and described radiator 3 pilot hole 31 near the end of described radiator 3 matches, and merge can along the lead 45 of described pilot hole 31 axially-movable; Described convex lens 5 are fixed on described loose collar 42; Described retaining spring 43 is placed on described lead 45, and its one end is connected with described loose collar 42, and the other end is connected with described housing 1 or described radiator 3.
Described rotating ring 41, because the cooperation of described annular groove 44 and position limiting structure, can only be rotated by relatively described housing 1 by described housing 1 restriction; When described rotating ring 41 rotates, described loose collar 42 moves because of the active force of described salient point 46 and described female thread structure or described retaining spring 43, after described retaining spring 43 compresses completely, can prevent described loose collar 42 from continuing to move to one end of described radiator 3, have stopping function; And described loose collar 42 is because the cooperation of described lead 45 and described pilot hole 31, is limited can only do translational motion along the axial of described lead 45 relative to described radiator 3 by described radiator 3.Described protecgulum and housing 1 form two circle rotation regulating mechanism.When rotating described rotating ring 41, described internal thread coordinates with described salient point 46, the rotary motion of described rotating ring 41 is converted to the translational motion vertically of described loose collar 42, thus changes described convex lens 5 and the distance of described light source 2, reach the object of focusing.
Further, described light source 2 is LED chip, and LED is green light source, has the features such as energy-saving and environmental protection, the life-span is long, volume is little.
