Abstract:
A palm-size laser projector light with annular lens and rotatable adjustment ring for changing patterns of emitted light comprising an adjustment ring, a disk cover, a disk, an annular lens, a laser generating component, and a plurality of connecting screws, wherein said adjustment ring is fitted at a disk rim of said disk and has an inner annular wall projecting from the bottom of an inner rim thereof, said disk cover covering the inner rim of said adjustment ring with a rim thereof urging against said inner annular wall, said screws being passed through said disk and said disk cover to lock them together so that said adjustment ring is sandwiched between said disk cover and said disk and is turnable at an outer periphery of said disk cover, said laser generating component being disposed between said disk and said disk cover and including a laser generator, a control circuit board, a switch, and at least one battery, said switch having a control portion exposed on said disk cover, said disk being formed with a through hole at a peripheral wall thereof to correspond to an emitting end of said laser generator so that laser light may emit from said disk, said annular lens being fixedly disposed at a lower end of said adjustment ring and being formed with a plurality of patterns of high transparency and different shapes, whereby after said adjustment ring is coupled to said disk, said annular lens is in front of said emitting end of said laser generator, and by turning said adjustment ring, any one of said patterns may be caused to be penetrated by the laser light to thereby obtain various light shapes.
