Abstract
A temperature control system for a light emitting diode assembly and associated lamp comprises a circuit board for supporting one or more light emitting diodes and a housing supporting the circuit board. A coolant circulation path is routed through the housing. The coolant circulation path is connected to a source of a substantially constant temperature circulating coolant. The temperature of the coolant is maintained around the constant by an internal combustion engine and a radiator.
Claims8
A lamp temperature control system comprising:
- a light source;
- means for supporting the light source;
- a coolant circulation path through the means for supporting;
- and
- an external source of coolant for circulation through the coolant circulation path which maintains coolant temperature upon entering the coolant circulation path at a substantially constant temperature.
A motor vehicle lighting system comprising:
- a circuit board;
- one or more light emitting diodes mounted on the circuit board;
- a housing supporting the circuit board;
- a coolant circulation path routed through the housing;
- the housing having connectors for connection to an external source of a circulating coolant;
- a lamp having an external surface with the lamp containing the circuit board and the housing;
- a radiator for circulating coolant through an engine;
- and
- connectors between the lamp and the radiator for circulating coolant from the radiator through the lamp.
A lamp comprising:
- a mounting board;
- one or more light emitting diodes supported on a major face of the mounting board;
- a housing supporting the mounting board;
- a cavity within the housing adjacent the mounting board;
- an inlet to and an outlet from the cavity;
- and
- means for circulating a fluid through the cavity by way of the inlet and the outlet.
