Abstract
A microwave-excited ultraviolet lamp system includes a microwave chamber supplied with cooling air from an air source. At least one of a pressure sensor or a temperature sensor is positioned within the system to sense a pressure associated with the flow of cooling air or a temperature of the lamp system. A control receives a signal from the sensor and is operable to adjust the flow of cooling air from the source to obtain a desired cooling air flow rate.
Claims9
A microwave-excited ultraviolet lamp system, comprising:
- a housing having an interior;
- a microwave chamber within said housing interior;
- a lamp bulb within said microwave chamber;
- a source of forced air communicating with said housing interior and providing a flow of air thereto;
- a pressure sensor configured to sense a pressure associated with said housing interior, said pressure sensor producing a signal associated with the pressure sensed by said pressure sensor;
- and
- a control receiving the signal from said pressure sensor and in response thereto, adjusting the flow rate of the air to a different, non-zero flow rate to maintain a desired spectrum of the lamp system.
A method of operating a microwave-excited ultraviolet lamp system having a housing, comprising:
- providing cooling air to the housing of the lamp system;
- sensing a pressure within the housing and associated with the cooling air;
- and
- adjusting a flow rate of the cooling air to a different, non-zero flow rate based on the sensed pressure to maintain a desired spectrum of the lamp system.
