Sterilizing apparatus

A light emitting apparatus, comprising;

• a housing comprising an outer surface facing a target and an inner surface opposite to the outer surface;
• a light source disposed on a substrate in the housing and configured to emit light toward the target,
• an irradiation opening configured to pass the light emitted from the light source;
• and
• a power supply configured to supply power to the light source,
• wherein the light source includes a first light emitter configured to emit having a peak wavelength in UV light range,
• wherein the first light emitter is disposed on the substrate and aligned with the irradiation opening while facing the irradiation opening, and
• wherein the irradiation opening has a diameter allowing at least 50% of light emitted from the first light emitter to pass therethrough.
