LIGHT EMITTING ELEMENT CIRCUIT, LIGHT TRANSMITTING SYSTEM, LIGHT TRANSMITTING MODULE, AND ELECTRONIC DEVICE

摘要

A light emitting element circuit has a light emitting element, a drive circuit that supplies a current to the light emitting element, and a signal circuit that autonomously supplies a signal according to an ambient temperature. The signal adjusts the current such that the current corresponds to a temperature characteristic of the light emitting element.
