Abstract
The present invention uniforms a size of an LED substrateto realize reduction of the number of parts and reduction of a manufacturing cost, and is a light irradiation device comprising: a long LED substrateon which a plurality of same LEDsare mounted; a chassishaving a substrate housing space for housing the LED substrate, wherein the number of LEDsin which a difference between a power source voltage Vand a sum of a forward voltage Vin the series connection of the LEDsis within an allowable range is employed as the number of LED units, and the number of LEDsmounted on the LED substrateis a common multiple of the number of LED units determined in each of LEDsof different wavelengths.
