Submersible lighting fixture with color wheel
First Claim
1. A method of controlling a motor operated by a control circuit comprising the steps of:
- disconnecting power to an input of the control circuit;
reconnecting power to the input of the control circuit;
the control circuit controlling the motor to move a driven element at a first speed;
the control circuit stopping the motor when the driven element reaches an index position; and
at a predetermined period of time after the step of reconnecting power, the control circuit controlling the motor to move the driven element at a second speed.

Abstract
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 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. A synchronization circuit is responsive to an alternating-current source of power applied to the lighting fixture.

6. A method of operating a control circuit for a lighting fixture comprising the steps of:
-
disconnecting power to the control circuit;
reconnecting power to the control circuit;
the control circuit causing the lighting fixture to emit a predetermined color of light; and
at a predetermined period of time after reconnecting the power, the control circuit controlling the lighting fixture to emit changing colors of light at a predetermined rate of change. - View Dependent Claims (7)

8. A lighting fixture comprising of:
-
a lighting system; and
a control circuit connected to control the lighting system wherein disconnecting and reconnecting power to an input of the control circuit a first time causes the lighting system to emit a predetermined color of light and then change the color of light emitted at a predetermined rate of change and further wherein disconnecting and reconnecting power to the input of the control circuit a second time causes the lighting system to emit the color of light emitted when the power was disconnected the second time.

9. An underwater lighting fixture adapted for installation in a lamp receiving recess in the wall of a swimming pool, said lighting fixture comprising:
-
a lamp housing having an interior cavity;
a plate mounted within said housing and being transverse to a longitudinal axis of said housing, said plate defining an opening;
a lamp having a reflector positioned at said opening on a first side of said plate so that said reflector is directed toward said open mouth;
a color wheel within said housing and mounted for rotation about said longitudinal axis, said color wheel having a plurality of dichroic radial filter segments, a driver mechanism for rotating said wheel, said color wheel sequentially positioning successive filter segments to the opening of said plate upon rotation of said wheel;
a transparent cover sealing the open mouth of said housing;
an electrical supply conduit extending through said lamp housing and into said interior cavity; and
a fluid seal between said supply conduit and said lamp housing and a power transformer within the lamp housing. - View Dependent Claims (10, 11)
