Abstract:
The multifunction LED lighting apparatus of the present invention includes at least one lighting LED, at least one ultraviolet (UV) LED, a substrate configured to have the at least one lighting LED and the at least one UV LED mounted thereon, and a cover disposed to face the substrate at a specific interval and configured to cover the lighting LED and the UV LED. The at least one lighting LED and the at least one UV LED are integrally mounted on the substrate and configured to form a single module of a thin sheet form, and the cover is installed to cover and support the single module placed on the inside wall of an application.
Abstract:
A sterilizer is provided to include: a first pipe having an inner wall with a light reflecting property; a second pipe disposed in the first pipe so as to pass fluid therethrough and formed of a light transmitting material; and a plurality of UV LEDs arranged on the inner wall of the first pipe and configured to irradiate sterilization UV light onto the fluid.
Abstract:
