A lighting fixture having a color-changing mechanism, such as a color wheel, for cycling through a plurality of colors, such as by rotating, at a first speed and a second speed. The second speed is faster than the first speed. A position pulse device, such as a position sensor, generates a reference position pulse when the color-changing mechanism is at a predetermined color or position. A circuit periodically generates a master pulse. A control device causes the color-changing mechanism to cycle through the colors at the second speed when the reference position pulse is generated after the master pulse.

Lighting fixture having two-speed color-changing mechanism

The lighting fixture includes a housing having an interior cavity and a transparent cover. A color-changing electric light assembly is provided in the interior cavity. The light assembly emits a plurality of different colors of light through the transparent cover and cycles through the plurality of different colors of light to sequentially emit each of the plurality of different colors of light. A synchronization circuit responds to a timed interruption in the power for synchronizing the color-changing electric light assembly with a color-changing electric light assembly of another underwater lighting fixture connected to the same power.

Color-changing submersible lighting fixture with control circuit responsive to timed interruptions of the power source

An underwater lighting fixture adapted for installation in a wall of a swimming pool. The lighting fixture includes a housing having an interior cavity and a transparent cover. A color changing electric light assembly is provided in the interior cavity. The light assembly emits a plurality of different colors of light through the transparent cover and cycles through the plurality of different colors of light to sequentially emit each of the plurality of different colors of light. An electrical conductor extends through the housing into the interior cavity for delivering power to the color changing electric light assembly. A synchronization circuit responds to a timed interruption in the power for synchronizing the color changing electric light assembly with a color changing electric light assembly of another underwater lighting fixture connected to the same power.

Underwater lighting fixture with color changing electric light assembly

An underwater lighting fixture adapted for installation in a wall of a swimming pool. The fixture includes a housing having an interior cavity and a transparent cover. A plate is mounted within the housing defines an opening. The plate has a first side facing the transparent cover and a second side opposite the first side. An electric light source includes a reflector positioned at the opening on the second side of the plate so that the reflector is directed toward the transparent cover. A color wheel within the housing is mounted for rotation and has filter segments. A driver mechanism within the housing rotates the color wheel, sequentially positioning successive filter segments to the opening of the plate. An electrical conductor extends through the housing into the interior cavity for delivering power to the electric light source and the driver mechanism.

Submersible lighting fixture with color wheel

An underwater lighting fixture adapted for installation in a lamp receiving recess in the wall of a swimming pool. The fixture includes a lamp housing having a pair of reflector-mounted incandescent lamps mounted therein. A plate having a pair of a apertures is mounted in the housing with the apertures mounted in alignment with the lamps. A pair of secondary reflectors are mounted to face the plate apertures and are provided with light-transmitting portals. A color wheel having dichroic filter segments is mounted so that identically colored pairs of segments pass the portals when the color wheel is driven by a motor. The motor is controlled by a circuit by disconnecting power to an input of the circuit, reconnecting power to the input to control the motor to move at a first speed. The control circuit stops the motor when the driven element reaches an index position. After the step of reconnecting power and after a predetermined period of time, the control circuit controls the motor to move the driven element at a second speed.
