Abstract

A moving head light for stage lighting includes a light sources group having a plurality of light sources, a reflector group slantwise arranged at a circumference of the light sources group; and an angle-adjusting device for adjusting the relative angles between the reflectors and the light sources. Each reflector corresponds to each light source one by one, and the reflector group includes a plurality of reflectors. The moving head light for stage lighting uses the angle-adjusting device to adjust the relative angles between the reflectors and the light sources so that lights sent out from the light sources generate a special effect of scaling in a space after being reflected by the reflectors.

Claims

1. A moving head light for stage lighting comprising:

a light sources group having a plurality of light sources;

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

an angle-adjusting device for adjusting the relative angles between the reflectors and the light sources,

wherein each reflector corresponds to each light source one by one, the reflectors are driven by the angle-adjusting device to deflect relative to the light sources, and the angle-adjusting device is arranged at a rear side of the reflectors.

2. The moving head light for stage lighting as claimed in claim 1, wherein the angle-adjusting device comprises an angle-feed mechanism and an angle-resetting mechanism.

3. The moving head light for stage lighting as claimed in claim 2,

wherein the angle-feed mechanism comprises an angle-driving motor, a cam driven by the angle-driving motor, an angle-pushing bracket movably contacted with the cam, an angle-adjusting bracket abutted against the angle-pushing bracket, and a fixed bracket securely connected with the angle-adjusting bracket;

and movable side plates for installing the reflectors are arranged on a side of the angle-adjusting bracket, an upper end of each movable side plate is fixed, and a lower end thereof is provided with a push rod extended through the fixed bracket to be movably abutted against the angle-pushing bracket.

4. The moving head light for stage lighting as claimed in claim 2, 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.

5. The moving head light for stage lighting as claimed in claim 3, 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.

6. The moving head light for stage lighting as claimed in claim 3, wherein the reflector group is driven by a rotary drive device to rotate around the light sources group.

7. The moving head light for stage lighting as claimed in claim 6, wherein the rotary drive device comprises a rotary drive motor, a first gear driven by the rotary drive motor, a second gear engaged with the first gear, and a shaft sleeve fixedly connected with the second gear, wherein the shaft sleeve is fixedly connected with the fixed bracket.

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

9. The moving head light for stage lighting as claimed in claim 8, wherein an included angles between the optic axis of the LED and the reflectors are 30-60 degrees.
