Title:
ゆらぎ信号生成装置、駆動回路、及び照明装置
Document Type and Number:
Japanese Patent JP5331415
Kind Code:
B2
Abstract:
To generate fluctuation signal, which does not depend on the environmental temperature but reflects fluctuation component of the temperature correctly.
The fluctuation signal generating circuit 2 includes a first thermocouple 3, a second thermocouple 4 with response speed slower than that of the first thermocouple 3, and a differential amplifier 5 outputting the difference between output of the first thermocouple 3 and output of the second thermocouple 4 as a fluctuation signal.
