LONG DISTANCE HIGH INTENSITY LED LIGHT WITH ADJUSTABLE FOCUS

摘要

The present invention provides a lighting device comprising (i) one or more LED chips positioned on one or more LED chip bases; (ii) one or more lens bases each of which comprises one or more lenses, said lens comprises coatings for changing color temperature of the light produced by said LED chips and transmitted through said lens; and (iii) a motion transmission system to change the position of said lens bases relative to said LED chip bases, wherein each of said lenses is placed along the light path of one or more LED chips, and said lens changes the light beam cone angle of light emitted from said LED chips to produce long distance high intensity illumination. In one embodiment, the lens bases can be moved in a direction parallel to the optical axes of said lens, or moved on a plane that is parallel to said LED chip bases.
