Abstract:
An image display device having improved properties, comprising an image display panel, heat dispersion material positioned proximate to the image display panel, an open frame positioned proximate to the heat dispersion material opposite the image display panel, and a plurality of electronic components engaging the open frame, the image display device exhibits a support factor of less than about 375 mm-W/m° K.
Abstract:
A projection image display device includes an indoor unit to be located indoors and an outdoor unit to be located outdoors. The outdoor unit includes a second refrigerant piping that forms a loop refrigerant path in combination with a first refrigerant piping, a cooling device, and a cooling control circuit that controls cooling for R, G, B laser heat sinks by the cooling device. The indoor unit includes a main control circuit that communicates with the cooling control circuit to control the cooling by the cooling device.
Abstract:
The invention provides a lighting unit (100) comprising (1) a vacuum ultraviolet (VUV) radiation based source of radiation (10) configured to generate VUV radiation (11), and (2) a luminescent material (20) configured to convert at least part of the VUV radiation into visible luminescent material light (21), wherein the luminescent material comprises a trivalent praseodymium containing material selected from the group consisting of (Zr1-x-yHfxPry)(Si1-yPy)04, (Zr1-x-yHfxPry)3((P1-3/4yS3/4y)04)4, and (Zr1-x-yHxPry)3((B1-3/4yX3/4y))O3)4, with x in the range of 0.0-1.0 and y being larger than 0 and being equal to or smaller than 0.15.
Abstract:
An irradiation device includes: a light source having an amalgam alloy member that is disposed on a part of the inner surface of a light source tube; and a chamber in which the light source is disposed. The chamber includes: a main chamber body; and a first gas inflow port and a first gas outflow port that are formed in the main chamber body. The first gas inflow port and the first gas outflow port are arranged so that the outer surface of the part of the light source tube where the amalgam alloy member is disposed is positioned in a flow path of a gas that flows in through the first gas inflow port and flows out through the first gas outflow port.
Abstract:
An apparatus for mounting and cooling a flat screen during operation comprises a housing for accommodating the flat screen and further heat generating electric and electronic units, moreover thermal bridges for conducting the heat generated by at least the flat screen to a heat conductive rear wall of the housing. The rear wall is provided with at least one profile in a manner that a plurality of chimney-like cavities are formed on the rear side of the housing, which comprise in their lower end portion at least one opening for supplying cool air into each cavity, and at least one outlet opening in the upper end portion of each cavity for discharging heated air into the atmosphere.
