Abstract:
1. A light emitting component on a substrate, comprising: a light emitting element; and a constant current circuit including a resistor element, whose resistance value is adjusted so as to set a light intensity of the light emitting element to a specified range, and a circuit including a transistor and/or a diode, the constant current circuit supplying a constant current to the light emitting element, wherein the light emitting element and at least a part of the circuit including the transistor and/or the diode are disposed on a surface of the substrate and the resistor element is disposed on another surface of the substrate; and the substrate has a rectangular shape and has a range of a side length ratio x/y between 1 and 1.5, wherein x is the length of a pair of opposite sides and y is the length of the other pair of opposite sides of the substrate.
