Abstract: A flash light includes a housing having a front end and a rear end to define a fixed length from the front to rear end. The housing further has a light cavity and a power cavity for receiving power source. The light arrangement includes a lens disposed at the front end of the housing, a light source disposed within the light cavity, and a light adjustor movably coupling with the housing to selectively adjust a distance between the lens and the light source along a longitudinal axis direction of the housing for adjusting the illumination angles of the light beam without altering the fixed length of the housing. The flash light is adapted for selectively adjusting illumination angles to provide variety of light patterns.

Abstract: A LED light device includes a light-emitting diode assembly including a light body and one or more LEDs supporting thereat, and a heat dissipating arrangement including a plurality of heat dissipating fins radially and outwardly extended from the light body to define a heat dissipating channel between every two of the heat dissipating fins, and an air guiding member coupled at the front side of the light body. Each of the heat dissipating channels has a front opening extended at the front side of the light body and an elongated side opening for dissipating heat generated from the LED assembly. An air guiding member has a plurality of guiding inlets aligning with the front openings of the heat dissipating channels respectively for guiding air flowing to the heat dissipating channels so as to effectively dissipating the heat from the LED assembly through the heat dissipating fins.
