Abstract
A mobile lighting source and control method therefor. The mobile lighting source includes a light source and a lens, where the lens and the light source are disposed coaxially. The light source includes several light regions, the light regions are disposed coaxially, and each of the light regions includes one or several light emitting units. The lens includes several light receiving members, the light receiving members are disposed coaxially, and the light receiving members project received light emitted from the light source to form a required light spot. The mobile lighting source and control method therefor provided in the present application achieve a zoom effect by arranging the lens with multiple light receiving members to refract the light emitted from the light source.
Claims8
A mobile lighting source, comprising a light source and a lens, wherein:
- the lens and the light source are disposed coaxially with respect to each other;
- the light source comprises a plurality of light regions, each of the light regions is either an inner light region or an outer light region, the inner light region and the outer light region are disposed coaxially with respect to each other, the outer light region surrounds the inner light region, and each of the light regions comprises one or a plurality of light emitting units;
- and
- the lens comprises a plurality of light receiving members, each of the light receiving members is either an inner light receiving member or an outer light receiving member, the inner light receiving member and the outer light receiving member are disposed coaxially with respect to each other, and the outer light receiving member surrounds the inner light receiving member;
- the inner light receiving member comprises a light focusing region and a diffusion region, the light focusing region and the diffusion region are disposed coaxially with respect to each other, and the diffusion region surrounds the light focusing region;
- a light receiving surface of the light focusing region faces a light emitting surface of the inner light region, and a light receiving surface of the diffusion region faces a light emitting surface of the outer light region;
- the light receiving members project received light emitted from the light source to form a required light spot;
- and
- the inner light receiving member comprises a lens barrel.
