Abstract:
1. A flash light, comprising: a hollow housing having a front end, a rear end to define a fixed length between said front end and said rear end, and a light cavity formed within said front end, wherein said housing further comprises two spaced apart blocking rims inwardly protruded from an inner wall of said housing within said light cavity thereof; and a light arrangement, which comprises: a convex lens affixed at said open front end of said housing for providing wider range of illumination angle; a light source, which is a LED light source, disposed within said light cavity for generating a light beam alignedly towards said lens; and a light adjustor movably coupling with said housing wherein said light source is moved along said longitudinal axis of said housing by said light adjustor to selectively adjust a distance between said light source and said lens for adjusting the illumination angle of said light beam without altering said affixed length of said housing, wherein said light adjustor comprises a light reflective platform slidably supported within said light cavity, wherein said light source is coupled at a center of said light reflective platform to coaxially align with said lens, such that when said light adjustor is actuated to move said light source, said light reflective platform of said light adjustor is correspondingly moved for enhancing a light intensity of said light source toward said lens, wherein a traveling distance of said reflective platform is limited between said blocking rims.
