Abstract

A stage lamp is composed of a lower casing, driving device, a support frame, eccentric device, a swing ring, and a globe shade. Once the power is on, the light bulb is lighted up and the output shaft of the driving device actuates to rotate the eccentric rod on the eccentric device. Therefore, the globe shade rotates eccentrically and the swing ring moves pivotally in an arc to make the colored light emitted through the globe shade has irregular lighting change for enhancing dynamic visual delight.

Claims

1. A stage lamp, comprising;

a lower casing with a top;

a driving device mounted in the lower casing and having an output shaft extending therefrom;

a support frame, having a lower frame plate with two ends and fixedly attached to the top of the lower casing, flap plates extending upwardly from the two ends of the lower frame plate and an inwardly extending pivot attached to each flap plate at a free end thereof;

an eccentric device, having a coupling head coupled to the output shaft, a transverse link extending from the coupling head, and an eccentric rod vertically disposed at a free end of the transverse link eccentric to the output shaft;

a swing ring disposed between the flap plates, having a pair of engaging holes pivotally engaging the pivots on the flap plates respectively, and having two ring pivots extending inwardly from opposite sides of the swing ring;

a global shade having a plurality of colored pieces on a surface thereof, and including a lamp socket extending outwardly therefrom with an electrical wire concealed in the lower casing, with a light bulb received therein and attached to the lamp socket, the globe having a fitting aperture receiving the eccentric rod so as to pivotally support the globe thereon, and two engaging holes engaging the ring pivots so as to be pivotally supported in the swing ring;

whereby, once the power is on, the light bulb is lighted and the output shaft rotates the eccentric rod such that the globe shade rotates eccentrically and the swing ring moves pivotally in an arc to make colored light emitted through the globe shade have irregular lighting changes.

2. The stage lamp as defined in claim 1, wherein the driving device is a motor.

3. The stage lamp as defined in claim 1, wherein axes passing through the engaging holes and through the ring pivots on the swing ring form an angle of 90°

with each other.

4. The stage lamp as defined in claim 1, wherein the electrical wire extending from the lamp socket is coiled.

5. The stage lamp as defined in claim 1, wherein support frame and the swing ring are made of injection molded plastic.
