Title:
【発明の名称】ガス放電ランプ用調整装置の過温度保護装置
Document Type and Number:
Japanese Patent JP2001508921
Kind Code:
A
Abstract:
An arrangement for protecting a control device for gas discharge lamps from overtemperature contains a control device and a DC/DC converter. Regulation of the power conveyed to the gas discharge lamp is performed. The output value of the power controller (to be considered the manipulated variable) and the input value of the power controller (to be considered the setpoint) are ascertained by way of the control device. The ratio of these two values (manipulated variable to setpoint) is determined. The value determined for that ratio can be used to limit the output power of the control device. The control device may contains a microcontroller, and the controller is provided as a program in the microcontroller and is implemented as software in order to limit the output power of the control device.
