Light assembly for a projector
View Patent ↗In one aspect, a light assembly system configured to be installed in a movie theatre projector includes a light assembly, which includes an adaptor configured to mechanically couple to a bulb mount of the movie theatre projector, LEDs attached to a primary LED Emitter mounting plate, a cooling assembly configured to dissipate heat from the primary LED Emitter mounting plate and a lens configured to collimate light emitted from the LEDs. The light assembly system also includes a light assembly control system, separate from an existing control system of the movie theatre projector, that is configured to control operation of the light assembly.
1. A light assembly system configured to be installed in a movie theatre projector, the light assembly system comprising:
a light assembly, comprising:
an adaptor configured to mechanically couple to a bulb mount of the movie theatre projector,
a primary Light Emitting Diode (LED) Emitter mounting plate;
at least one LED directly or indirectly attached to the primary LED Emitter mounting plate;
a cooling assembly configured to dissipate heat from the primary LED Emitter mounting plate; and
a lens configured to collimate light emitted from the at least one LED; and
a light assembly control system, separate from an existing control system of the movie theatre projector, configured to control operation of the light assembly.
2. The light assembly system of claim 1 , wherein the light assembly control system is a standalone system external to the light assembly and comprises a driver to power the at least one LED.
3. The light assembly system of claim 1 , wherein the light assembly control system is configured to interface with the existing control system of the movie theater projector with regard to when the light assembly is to operate.
4. The light assembly system of claim 1 , wherein the cooling assembly comprises at least one of:
a heat sink configured to dissipate heat from the primary LED Emitter mounting plate;
a cooling fan configured to pass air over the heat sink; and
one or more thermal pads in contact with the primary LED Emitter mounting plate.
5. The light assembly system of claim 4 , wherein the cooling assembly comprises a heat sink and a cooling fan, and wherein the light assembly system further comprises a driver to power the cooling fan.
6. The light assembly system of claim 5 , wherein the light assembly comprises a heat sink coupled to the primary LED emitter mounting plate, and wherein the light assembly system further comprises an air guide that is configured to direct air from an air movement system of the movie theater projector over the heat sink.
7. The light assembly system of claim 1 , wherein the light assembly control system is configured to utilize a power source that is separate from a power source for the movie theatre projector.
8. A light assembly system configured to be installed in a movie theatre projector, the light assembly system comprising:
a light assembly, comprising:
an adaptor configured to mechanically couple to a bulb mount of the movie theatre projector,
a primary Light Emitting Diode (LED) Emitter mounting plate;
at least one LED directly or indirectly attached to the primary LED Emitter mounting plate;
a cooling assembly configured to dissipate heat from the primary LED Emitter mounting plate;
a lens configured to collimate light emitted from the at least one LED; and
a light assembly control system configured to control operation of the light assembly and the movie theatre projector.
9. A method of installing a light assembly in a movie theatre projector, the light assembly comprising an adaptor configured to mechanically couple to a bulb mount of the movie theatre projector, at least one LED attached to a primary LED Emitter mounting plate, a cooling assembly configured to dissipate heat from the primary LED Emitter mounting plate, and a lens configured to collimate light emitted from the at least one LED, wherein the method comprises:
placing a light assembly control system in or proximate to the movie theatre projector, wherein the light assembly control system is separate from an existing control system of the movie theatre projector and configured to control operation of the light assembly;
inserting the light assembly into the movie theatre projector by mechanically coupling the adaptor to the bulb mount;
electrically coupling the light assembly to the light assembly control system; and
establishing a communication link between the light assembly control system and the existing control system of the movie theatre projector.
10. The method of claim 9 , further comprising configuring the light assembly control system to receive instructions from the existing control system of the movie theater projector with regard to when the light assembly is to operate.
11. The method of claim 9 , wherein the light assembly comprises a heat sink coupled to the primary LED emitter mounting plate, and wherein the method further comprises installing an air guide such that a hole of the air guide is positioned to direct air from an air movement system associated with the movie theater projector over the heat sink.
