Title:
光源制御装置
Document Type and Number:
Japanese Patent JP7359689
Kind Code:
B2
Abstract:
To provide a light source controller capable of reducing cost even if whose configuration has a temperature sensitive resistor and a momentary switch.SOLUTION: A light source controller 1 is configured to include: a control unit 110; an LED power supply circuit 10; a PWM control circuit 11; a detection circuit 12; an LED 211; a momentary switch 213; and a temperature sensitive resistor 214. In the control unit 110, operation detection of the momentary switch 213 and temperature detection by the temperature sensitive resistor 214 are detected by a single terminal. When the momentary switch 213 is operated, the control unit 110 controls lighting and turning off of the LED 211, and further controls luminance of the LED 211 by the PWM control circuit 11 on the basis of temperature detection results.SELECTED DRAWING: Figure 2
