Abstract: A lighting device including at least one first light source configured to emit a visible light through a first light emitting surface, at least one second light source spaced apart from the first light source and configured to emit light having a wavelength for sterilization through a second light emitting surface, and a housing having a bottom portion, on which the first and second light sources are disposed. The housing can include at least one sidewall portion connected to the bottom portion to enclose the first light source and the second light source in one common area, in which the first and second light emitting surfaces face substantially the same direction, and both the first light emitting surface and the second light emitting surface can be disposed at a different elevation from the bottom portion of the housing.

Abstract: A fluid treatment module includes a pipe providing a flow channel in which fluid flows, the pipe having an inlet and an outlet, a light source module including a substrate and at least one light emitting diode disposed on an upper surface of the substrate and emitting light into the pipe to treat the fluid, a reflector disposed inside the pipe to reflect the light emitted from the light source module and having higher reflectivity with respect to the light than the pipe, and a heat dissipation plate contacting a rear surface of the substrate to dissipate heat from the light source module. The inlet, the outlet, or both are provided in plural to allow a flow speed and a flow direction of the fluid flowing into the pipe to be controlled, and the heat dissipation plate has higher thermal conductivity than the substrate.

Abstract: A fluid treatment device includes a pipe including an inlet, an outlet, an internal space through which a fluid moves and including a light source part disposed in the internal space and providing a light to the fluid. The light source part includes at least one light source unit having a substrate and a plurality of light sources disposed on the substrate and emitting the light. A ratio of a first distance between two light sources adjacent to each other to a second distance between each light source and an inner circumferential surface of the pipe is 1:1.25 or less when viewed in a longitudinal-section.
