特徴とする道路反射鏡用発光装置。 A road reflector equipped with solar cells and storage batteries, two-color red and yellow light-emitting diodes, and separate light-receiving and emitting plates each equipped with a photoelectric conversion element on the left and right sides of the mirror body. The element is connected to the lower stage, the volume is connected to the lower stage, and the next stage has a differentiating circuit consisting of a capacitor and a resistor, and the output of the differentiating circuit and the reference voltage are compared with a comparator and output from two vehicle sensor sections. Judging by a control section consisting of an oscillation circuit, an AND circuit, and an OR circuit, when only one of the outputs of the vehicle sensor section is at a high level, the two-color light emitting diode emits yellow light, and when both outputs are at a high level. A light-emitting device for a road reflector, characterized in that a two-color light-emitting diode is configured to flash red light.
