Abstract
There are provided a light irradiation device and a light irradiation system which are capable of correcting changes in optical power output. A light irradiation device includes: a substrate having an upper surface provided with a first recess and a second recess; a light-emitting element located in the first recess, the light-emitting element emitting ultraviolet light; and a detecting element located in the second recess, the detecting element being capable of detecting ultraviolet light.
Claims11
A light irradiation device, comprising:
- a substrate having an upper surface provided with a first recess and a second recess;
- a light-emitting element located in the first recess, the light-emitting element emitting ultraviolet light;
- a detecting element located in the second recess, the detecting element being capable of detecting ultraviolet light that is emitted from the light-emitting element and transmitted through the substrate;
- and
- an ultraviolet shield member which covers the detecting element in a state of being be apart therefrom, wherein the ultraviolet shield member closes an opening of the second recess, and is capable of transmitting infrared light.

A light irradiation device, comprising:
- a substrate having an upper surface provided with a plurality of first recesses and a second recess;
- a light-emitting element located in at least one of the plurality of first recesses, the light-emitting element emitting ultraviolet light;
- a detecting element located in the second recess, the detecting element being capable of detecting ultraviolet light that is emitted from the light-emitting element and transmitted through a portion of the substrate;
- and
- an ultraviolet shield member which covers the detecting element in a state of being be apart therefrom, wherein the ultraviolet shield member closes an opening of the second recess, and is capable of transmitting infrared light;
- wherein the portion of the substrate is located between the plurality of first recesses and the second recess and the portion of the substrate is smaller in thickness than a second portion of the substrate located between adjacent ones of the plurality of first recesses.
