Summary of the invention

In the technical deficiency of focus adjustment, the utility model provides a kind of simple in structure, the easy electromotion focusing LED of focus adjustment light fixture for existing LED light fixture.

For achieving the above object, the utility model is taked following technical scheme:

A kind of electromotion focusing LED light fixture, comprise drive end bearing bracket, LED lamp plate, radiator, focal length adjustment device, rear end cap, base, fixed support, described drive end bearing bracket is connected by fixed screw with radiator, described rear end cap is connected by fixed screw with radiator, described base is connected by fixed screw with rear end cap, described focal length adjustment device is arranged in the inner chamber of base and rear end cap formation, and is connected with the rear end cap lower end by fixed screw.

Further, described LED lamp plate is fixed on the radiator top, on lamp plate, is uniformly distributed LED light source, and is provided with 4 manholes in LED lamp plate edge symmetric position.

Described focal length adjustment device comprises set of lenses, bearing guide rod, limiting plate, lifter plate, focusing support, motor and motor shaft sleeve.

Described set of lenses is that two aluminium panels clampings and fixing a plurality of lens form, and is provided with 4 threaded circular apertures in the edge symmetric position.

Described limiting plate four end symmetric positions are provided with 4 manholes, and limiting plate is connected and fixed by screw and focusing support.

Described lifter plate four end symmetric positions have 4 manholes.

Described focusing support four end symmetric positions are provided with 4 not penetrating shallow slots of circle.

Described focusing support, lifter plate and limiting plate are provided with manhole in center, and described motor is arranged on focusing support below, and the rotating shaft on motor passes the manhole on focusing support, motor shaft sleeve, lifter plate and limiting plate successively.

Described lifter plate and the middle motor shaft sleeve that is provided with of focusing support.

Described bearing guide rod upper end is connected by screw with the threaded aperture on set of lenses, then passes successively the manhole on LED lamp plate, limiting plate, lifter plate, and insert in the not penetrating shallow slot of circle on the focusing support lower end.

The beneficial effects of the utility model are: because the utility model adopts power-driven focusing mechanism, can realize that the LED light fixture simply, fast realizes focus adjustment, adopt in the past the deficiencies such as the manual focusing process is loaded down with trivial details, focusing accuracy is poor thereby solve; By optimal design, reduce number of motors, can reduce LED light fixture Material Cost, can be widely used in the illumination of stage video display performing art, make the fields such as scape and landscape light in city.
