Abstract
A sterilization apparatus includes a light source unit for emitting light to a sterilization region for sterilizing a target particle, a power supply unit for supplying power to the light source unit, and a photodiode unit for sensing the light from the light source unit. The photodiode unit is driven by the light from the light source unit.
Claims17
A light radiation module comprising:
- a first light source disposed on a substrate and configured to emit first light toward target particles in a sterilization region and sterilize the target particles;
- a power supply electrically connected to the first light source and configured to supply power to the first light source;
- a second light source disposed on the substrate and configured to emit second light and detect a presence of the target particles;
- a photodiode configured to detect the second light from the second light source and configured to generate power based on the second light source that is electrically disconnected from the power supply, the photodiode connected to the second light source and operating as a photocell generating the power and providing the power to the second light source to operate the second light source without being connected to the power supply;
- a first sensor disposed adjacent to the photodiode and configured to detect the first light, the first sensor connected to the photodiode and being powered by the photodiode;
- and
- a controller electrically connected to each of the first light source, the second light source, the power supply, and the photodiode and configured to control the power supply based on a detection of the second light by the photodiode.

A sterilization apparatus comprising:
- a sterilization region where particles enter and stay;
- a light radiation module comprising:
- a first light source disposed on a substrate and configured to emit first light and coupled to the sterilization region such that the first light emitted from the first light source reaches the particles in the sterilization region and sterilizes the particles;
- a power supply electrically connected to the first light source and configured to supply power to the first light source;
- a second light source disposed on the substrate and configured to emit second light and detect a presence of the particles;
- a photodiode arranged to detect the second light from the second light source without being connected to a power supply electrically connected to the first light source, the photodiode configured to operate as a photocell generating power based on the second light source that is electrically disconnected from the power supply and provide the power to the second light source to operate the second light source without being connected to the power supply;
- a first sensor disposed adjacent to the photodiode and configured to detect the first light, the first sensor connected to the photodiode and being powered by the photodiode;
- and
- a controller electrically connected to the first light source, the second light source, the power supply, and the photodiode and configured to control the power supply based on a detection of the second light by the photodiode.
