Abstract

The present invention discloses a moving head light included a light source group having a plurality of light sources, a reflector group slantwise arranged at a circumference of the light source group, and a rotary drive device for driving the reflector group to rotate relative to the light source group. Each reflector corresponds to each light source one by one, and the reflector group includes a plurality of reflectors. The reflectors are rotated around the light sources, so that the lights sent out from the light sources are projected to the space after being reflected by the reflectors, and the faculae are divided into two from one and jointed into one from two. Accordingly, the stage rendering effect is better and a sort of fantasy feel is produced for persons.

Claims

1. A moving head light comprising:

a light source group having a plurality of light sources;

a reflector group slantwise arranged at a circumference of the light source group, and the reflector group having a plurality of reflectors; and

a rotary drive device for driving the reflector group to rotate relative to the light source group, wherein each reflector corresponds to each light source one by one.

2. The moving head light as claimed in claim 1, wherein the rotary drive device comprises the rotary drive motor, a first gear driven by the rotary drive motor, a second gear engaged with the first gear, a shaft sleeve fixedly connected with the second gear, a fixed bracket extended through the shaft sleeve, and a rotation bracket integrally assembled with the fixed bracket.

3. The moving head light as claimed in claim 2, wherein the rotation bracket is formed to have a plurality of side plate for mounting the reflectors thereon.

4. The moving head light as claimed in claim 3, wherein each side plate is movable, and an upper end of the side plate is positioned, and a lower end of the side plate can be rotated under the action of external force.

5. The moving head light as claimed in claim 4, wherein an angle-adjusting device is arranged at a rear side of each of the side plate, and the angle-adjusting device comprises an angle-pushing mechanism and an angle-resetting mechanism therein.

6. The moving head light as claimed in claim 5, wherein the angle-pushing mechanism comprises an angle-driving motor, a cam driven by the angle-driving motor, an angle-pushing bracket movably connected with the cam, a push rod disposed on the rear side of each movable side plate, and the push rod is extended through the fixed bracket to be movably abutted against the angle-pushing bracket.

7. The moving head light as claimed in claim 6, wherein the angle-resetting mechanism is an elastic resetting mechanism comprising a spring column extended through the fixed bracket and a resetting spring arranged at a periphery of the spring column;

and one end of the resetting spring is positioned at a distal end of the spring column, and the other end thereof is abutted against the fixed bracket.

8. The moving head light as claimed in claim 6, wherein a bottom portion of the angle-pushing bracket is provided with a plurality of guiding sleeves, and the fixed bracket is provided with a plurality of guiding columns matched with the guiding sleeves.

9. The moving head light as claimed in claim 1, wherein the light source is an LED, and the luminous angle of the LED is 100-140 degrees.

10. The moving head light as claimed in claim 9, wherein an included angle between the optic axis of the LED and the reflector is 30-60 degrees.
