    摘要: The present invention generally relates to the field of lighting devices, and in particular to a lighting device that is suitable for providing disinfection of an area and/or surrounding environment. The lighting device (100) according to the present invention comprises a light source (101), a first reflector (102), and a second reflector (103). The light source (101) is configured to provide, in operation a light output (111). The first reflector (102) comprising a first reflective surface (121), and the second reflector (103) comprising a second reflective surface (131). The first reflective surface (121) is configured face the second reflective surface (122). The light source (101) is configured to emit the light output (111) towards the second reflective surface (131). The second reflective surface (131) comprises a plurality of sections (133), each section (133) comprising a first section surface (134) that faces away from a center axis (001) of the light source (101) and a second section surface (135) that faces towards the center axis (001). The first section surface (134) comprises a light reflective surface.

    摘要: Aspects of the invention provide a system for disinfecting a humidifier containing a volume of water. An enclosure, such as a humidifier, includes a first chamber, a second chamber, a humidifier component, a third chamber, and a control unit. The first chamber contains a volume of water and a portion of the water flows into the second chamber. A first set of ultraviolet radiation sources within the first chamber can be configured to generate UV-A radiation, while a second set of ultraviolet radiation sources within the second chamber can be configured to generate UV-C radiation. In operation, the humidifier component adjacent to the second chamber creates water vapor using the portion of the volume of water within the second chamber. The water vapor flows into a third chamber that contains the water vapor and releases the water vapor into the ambient.

    摘要: A box-shaped UV disinfection system (100) comprises a plurality of internal UV sources (121, 122, 131, 132, 141, 142) disposed on at least two of its walls (120, 130, 140) that are adjacent to each other, all of the internal wall surfaces having a reflectance higher than 80% and preferably higher than 87% in the wavelengths range between 250 and 350 nm, and a UV-transmitting support (101) that has at least a 70% UV transmittance in said wavelengths range and is located at a suitable minimum distance from the base wall (110), the UV sources (131, 132, 141, 142) disposed on at least one of its walls (130, 140) being inclined towards the base wall (110) with an angle comprised between 5° and 30°. Such a system has improved characteristics in terms of efficiency and in a preferred embodiment also has better portability.
