Abstract
A system for monitoring an excimer bulb includes a thermoelectric energy harvester configured to be located adjacent to the excimer bulb and to convert thermal energy from the excimer bulb into electrical energy having a voltage. The system further includes a controller in electrical communication with the thermoelectric energy harvester and configured to calculate at least one of a remaining useful life of the excimer bulb or a current temperature of the excimer bulb based on the voltage of the electrical energy converted by the thermoelectric energy harvester.

A system for monitoring an excimer bulb, the system comprising:
- a thermoelectric energy harvester configured to be located adjacent to the excimer bulb and to convert thermal energy from the excimer bulb into electrical energy having a voltage;
- and
- a controller in electrical communication with the thermoelectric energy harvester and configured to calculate at least one of a remaining useful life of the excimer bulb or a current temperature of the excimer bulb based on the voltage of the electrical energy converted by the thermoelectric energy harvester.
A system for monitoring an excimer bulb, the system comprising:
- a thermoelectric energy harvester configured to be located adjacent to the excimer bulb and to convert heat from the excimer bulb into electrical energy having a voltage;
- and
- a controller in electrical communication with the thermoelectric energy harvester and configured to:
- calculate a current temperature of the excimer bulb based on the voltage of the electrical energy converted by the thermoelectric energy harvester, and
- calculate a remaining useful life of the excimer bulb based on at least one of the voltage of the electrical energy converted by the thermoelectric energy harvester or the current temperature of the excimer bulb.
A method for monitoring an excimer bulb, the method comprising:
- converting, by a thermoelectric energy harvester, thermal energy received from an adjacent excimer bulb into electrical energy having a voltage;
- and
- calculating, by a controller, at least one of a remaining useful life of the excimer bulb or a current temperature of the excimer bulb based on the voltage of the electrical energy converted by the thermoelectric energy harvester.
