Patent ID: 8393751

Claim:
A flash light, comprising: a hollow housing having an open front end, a closed rear end defining a fixed length between said front end and said rear end, a light cavity formed within said front end, and a power cavity formed at said rear end for receiving a power source within said power cavity; and a light arrangement, which comprises: a lens coaxially supported at said front end of said housing: a light source, which is a LED, disposed within said light cavity for generating a light beam alignedly towards said lens; and a light adjustor movably coupling with said housing to selectively adjust a distance between said light source and said lens along a longitudinal axis of said housing for adjusting an illumination angle of said light beam without altering said affixed length of said housing, wherein said light adjustor comprises a light supporter disposed within said light cavity to support said light source, and a sleeve actuator which is rotatably and coaxially coupling with an outer circumferential surface of said housing within said light cavity thereof and is arranged to drive said light supporter to reciprocatingly move along said longitudinal axis of said housing so as to selectively adjust said distance between said light source and said lens, wherein said housing further comprises a tubular conductive holder affixed within said power cavity to electrically contact with said light supporter so as to ensure said light source being electrically connected with said power source when said light source is moved, wherein said light supporter comprises a tubular conductor extending rearwardly to slidably contact with said conductive holder, such that when said light source is reciprocatingly moved along said longitudinal axis of said housing, an outer circumferential surface of said tubular conductor is slidably contacted with an inner circumferential surface of said conductive holder to ensure light source being electrically connected with said power source.
