摘要： PROBLEM TO BE SOLVED: To provide an abnormality detection device for light emitting device and an abnormality detection method for light emitting device that can reduce misdetection of abnormality of a light emitting device.SOLUTION: Once detecting a channel of an error voltage such that a detection voltage determined by a current flowing to an LED 20 of each channel is lower than an abnormality detection voltage in a normal current state, a CPU 10 increases the current of the channel whose error voltage is detected, and forcibly decreases the duty ratio of a pulse width of the channel whose error voltage is detected to create a current increase state. With respect to the channel whose error voltage is detected, the CPU 10 disables the channel whose error voltage is detected again to be used when detecting the error voltage again in the current increase state, and puts the channel back into the normal current state when not detecting the error voltage again.
