1. An air purifier comprising:
a case having a first surface, a second surface opposing the first surface, a sidewall connecting the first surface and the second surface, an air inlet disposed on the sidewall and an air outlet, wherein the air outlet is located at the second surface that is spaced apart from the first surface along a first direction;
a fan disposed inside the case and having a body, an inlet aligned with the air inlet of the case to expedite an entry of air into the case and an outlet for discharging introduced air towards a fluid control structure, the inlet of the fan structured to introduce air along a second direction perpendicular to the first direction and perpendicular to the sidewall and the outlet of the fan structured to discharge air through the outlet of the fan along the first direction;
a light source disposed in the case and comprising a substrate and a plurality of light emitters disposed on the substrate, the plurality of light emitters comprising a first light emitter configured to emit a first light and a second light emitter configured to emit a second light having a different peak wavelength from that of the first light; and
a filter arranged inside the case and disposed between the air inlet and the air outlet of the case;
wherein the fluid control structure is disposed inside the case and positioned between the fan and the air outlet, the fluid control structure including a first duct part arranged adjacent to the outlet of the fan and having a region with an increasing width along a flow path of air, and
wherein the light source further comprises a light reflector disposed on the substrate and surrounding at least one of the first light emitter or the second light emitter, the light reflector having a side surface that connects a bottom of the light reflector to a top of the light reflector and faces a side of the at least one of the first light emitter or second light emitter at a predetermined angle with respect to the substrate, wherein at least a portion of the side surface of the light reflector has a width increasing in a direction from the bottom of the light reflector and the top of the light reflector, and wherein the light reflector is connected to the substrate via a connector.
