Abstract
A light irradiation device includes a substrate, a light-emitting unit, a package layer and a thermal conductive layer. The light-emitting unit is disposed on the substrate. The package layer is disposed at one side of the light-emitting unit away from the substrate. The thermal conductive layer is disposed at one side of the package layer away from the light-emitting unit. The light transmittance of the thermal conductive layer ranges from 80% to 99%. The light-emitting unit is configured to emit a light having a wavelength between 650 nm and 830 nm, and the light intensity range of the light is set from 1 mW/cm2 to 200 mW/cm2.
