MOTOR ASSEMBLY FOR SLOWING DOWN FALLING SPEED OF STAGE LIGHT FIXTURE ON POWER FAILURE, AND STAGE LIGHT FIXTURE
A motor assembly for slowing down falling speed of a stage light fixture on power failure includes a motor driver, an automatic transfer switch, a capacitive load, and an alternating current motor. In the case that the automatic transfer switch is energized, windings of the alternating current motor are kept connected to the motor driver, and in the case that the automatic transfer switch is deenergized, the windings of the alternating current motor are switched to be connected to the capacitive loads. The motor assembly according to the present disclosure can reduce the falling speed of the stage light fixture in case of the power failure.

SELF-EXTINGUISHING CANDLE
A lid for a candle is provided. The lid comprises an inner housing which includes an inner housing aperture, as well as an iris including an iris guide section and at least two blades. The iris guide section has a respective blade guide slot for each of the at least two blades. Each of the at least two blades has opposing ends, and at least one bolt aperture at each of the opposing ends. A respective bolt extends through each at least one blade guide slot and each bolt aperture thereby engaging the at least two blades with the iris guide section. The iris has an open position and a closed position. In the open position, the inner housing aperture of the lid is open, and in the closed position, the blades of the iris extend over the inner housing aperture, thereby closing the inner housing aperture.
Lamp strip
The present invention provides a lamp strip, wherein the lamp strip comprises an outer casing, an inner casing and a light-emitting component, the light-emitting component comprises a substrate and an LED light source, wherein the inner casing is provided with a light exit through which the light of the LED light source directly passes. Cut marks are arranged between the light exits, and the side facing the LED light source of the outer casing is of light transmission. The invention facilitates the user to cut the lamp strip and greatly prolongs the service life of the lamp strip.
