Claim:
1. A lighting device comprising: a. one or more LED chip bases each of which comprises one or more LED chips; b. one or more lens bases each of which comprises one or more lenses, said lens comprises coatings for changing the color temperature of light emitted by said LED chips and transmitted through said lens; and c. 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 lenses change the light beam cone angle of light emitted from said LED chips to produce long distance high intensity illumination, wherein said motion transmission system includes a shock-resistant configuration for protecting a shaft of a motor from impact along longitudinal direction of said shaft, said mechanism comprising (i) a motor comprising a cover and a shaft, said shaft comprises at least one flat longitudinal surface, and (ii) a driving bolt with an inner hole, the shape of said inner hole matches the cross-sectional shape of said shaft, wherein said shaft is coupled to said bolt through said inner hole such that said driving bolt can slide along said shaft when an impact force in the longitudinal direction of said shaft is applied on said driving bolt, wherein when said shaft rotates, rotational force is directly transmitted from the shaft to the driving bolt, wherein when an impact force in the longitudinal direction of the shaft is applied to said driving bolt, said impact force is transmitted onto the cover of the motor and not on said shaft.
