Abstract:
A method for producing a molybdenum film for lamp construction is provided. The method may include roughening at least a part of the surface of the molybdenum film by sandblasting with a sandblasting means, wherein the sandblasting means contains at least one of aluminum oxide and quartz sand as well as at least one further component.
Abstract:
Embodiments provide a halogen lamp configured to minimize a short circuit of a filament.Provided is a halogen lamp that includes a support part passing through a bulb and disposed in the bulb. A filament is hung on the support part. Thus, a short circuit of the filament is minimized.
Abstract:
A flat discharge lamp includes a projection formed on an outer surface of a case body. The projection forms a thick portion, which is relatively thick, in the case body. An intake-outtake port is formed in the thick portion so that it can receive a chip tube having an outer diameter of a size larger than or the same as a gap. The large chip tube can be coupled to a hermetic case without any limitations resulting from the gap of a discharge chamber (15). The large chip tube resists damaging and improves gas replacement efficiency in the discharge chamber without affecting discharge characteristics of the flat discharge lamp.
Abstract:
There are provided electrode emission source components (105) and electrical apparatus comprising the same. In one embodiment an electrode emission source component comprises a tubular metal body (107) having first and second open ends (140, 150). Also provided are methods of forming electrode components.
Abstract:
A connecting member is adapted to be coupled with a connection object including a pipe portion having a sealed end and a terminal portion protruding outward from the sealed end. The connecting member includes a tubular portion adapted to be fitted over an outer peripheral surface of the pipe portion, a bottom portion connected to one end of the tubular portion in an axial direction and adapted to be faced to the sealed end when the tubular portion is fitted over the outer peripheral surface of the pipe portion, and a connecting portion connected to the bottom portion and adapted to be connected to the terminal portion. The tubular portion includes a plurality of elastic sections separated by a plurality of slits extending from the other end towards the one end in the axial direction and adapted to be brought into elastic contact with the pipe portion.
Abstract:
A backlight assembly includes a receiving container having a bottom and a side member to provide a receiving space, a flat-type fluorescent lamp received into the receiving container to emit a light, and a supporting member having a buffer disposed between the receiving container and the flat-type fluorescent lamp to buff an impact applied to the flat-type fluorescent lamp while supporting the flat-type fluorescent lamp. The buffer has protrusions protruding from a face of the supporting member. Thus, the backlight assembly may enhance impact resistance of the backlight assembly and prevent damage of the flat-type fluorescent lamp.
Abstract:
A field emission device (100, 200) includes an anode (190); a substrate (110); a plurality of spaced apart cathodes (120); a dielectric layer (124) disposed on the cathodes (120); a plurality of spacer pads (130, 230) disposed on the substrate (110) between adjacent cathodes (120) and including a spacer contact layer (142, 185) that defines the surfaces of the spacer pads (130, 230); a spacer (150) having a first edge (157), a second edge (155), and a conductive layer (152) disposed on the second edge (155), the first edge (157) contacting the anode (190), the conductive layer (152) contacting the spacer contact layer (142, 185) at the spacer pads (130, 230); and an electron emitter (170) disposed within the dielectric layer (124) and spaced apart from the second edge (155) of the spacer (150).
Abstract:
The present invention involves a short arc discharge lamp having a quartz envelope with a bulb and a plurality of arms having a specified cross-section, and wherein one or more electrode rods are supported within the lamp arms for specific alignment. Support elements for the electrode rods are made of high temperature metal and have a flat central portion with a central orifice of sufficient dimension to permit one of the electrode rods to pass into the central orifice, and have at least two legs, and preferably four legs, radially extending from the flat central portion. The legs have outer portions terminating with pods formed at substantially right angles to the flat central portion of the support element, the legs being of sufficient length to fit the support element within a specified cross-section of the envelope arms so as to contact an inside surface of the envelope arms with the pods. There is also provided means for securing the support elements within the envelope arms.
Abstract:
A RECTANGULAR SHADOW-MASK TYPE COLOR PICTURE TUBE HAVING A SHADOW MASK COMPRISING AN APERTURED MASKING PORTION OF SPHERICAL CONTOUR AND HAVING A RECTANGULAR PERIPHERAL SKIRT PORTION ATTACHED TO ONE FLANGE OF A BARREL-SHAPED RECTANGULAR FRAME OF UNIFORM L-SHAPED CROSS SECTION, THE OTHER FLANGE OF WHICH EXTENDS INWARDLY TO SERVE AS AN ELECTRON SHIELD FOR THE SKIRT AND ONE FLANGE DURING OVERSCAN OF THE BEAM AT MAXIMUM DEFLECTION ANGLES. THE DIFFERENCE IN CURVATURE OF THE LONG AND SHORT SIDES OF THE BARREL-SHAPED FRAME IS SUCH THAT THE PORTIONS OF THE FRAME TO WHICH THE MOUNTING SPRINGS ARE ATTACHED LIE SUBSTANTIALLY IN A COMMON PLANE PERPENDICULAR TO THE CENTRAL TUBE AXIS, THUS PERMITTING THE USE OF IDENTICAL SPRINGS.
