Abstract:
A light source device has an internal electrode (24) disposed at an end portion inside a bulb (23), and an external electrode (25) disposed outside the bulb (23). A holder member (27) holds the external electrode (25) so as to be opposed to the bulb (23) with a predetermined spacing (26). A dielectric member (30) is disposed outside the bulb (23), at a position corresponding to the internal electrode (24) so as to be interposed between the bulb (23) and the external electrode (25).
Abstract:
In a lamp that prevents outflow of mercury filled in a lamp tube and a liquid crystal display apparatus having the lamp, the lamp includes a lamp tube and an electrode. The lamp tube is filled with a discharge gas and a fluorescent material. The electrode is disposed on both ends of the lamp tube. An insulating adhesive material is interposed between the lamp tube and an insertion hole into which the lamp tube is inserted. The lamp tube is combined with the electrode by the insulating adhesive material. A pin hole that may be generated in the lamp tube corresponding to the insertion hole of the electrode is sealed. Thus, outflow of the mercury in the lamp tube may be prevented.
Abstract:
A liquid crystal display module includes: a liquid crystal display panel, a surface light-emitting lamp irradiating light to the liquid crystal display panel by a surface light-emission, and a power source supplying an electric power to the surface light-emitting lamp. The surface light-emitting lamp includes a frame having a light-emitting space, a first barrier rib formed partitioning the lamp into light-emitting spaces and electrode pairs for generating electric fields in the light-emitting spaces, respectively.
Abstract:
The disclosed subject matter includes a fluorescent lamp and particularly a cold cathode fluorescent lamp that can be employed as a light source for a LCD backlight unit for a television, a computer, a display, and the like. The fluorescent lamp can include a couple of electrode units located opposite to each other at each end of a tube, a couple of welding beads sealing both the tube and the couple of electrode units, and a filler gas located in the tube. Each of the electrode units can include an emitter electrode that is configured with a crystalline silicon carbide material having an electrical conductivity and including a concave portion formed thereon. The electrode units can prevent blackening on an inner surface of the tube by avoiding the occurrence of spattering. Thus, the fluorescent lamp using the electrode units can enjoy a long life, high reliability, easy manufacture, and the like.
Abstract:
The invention relates to a low-pressure discharge lamp comprising a glass discharge vessel (1) which is substantially tubular in form and which is closed in a gas-tight manner on the ends thereof, a filling consisting of an inert gas mixture and quicksilver, in addition to an optional luminous coating on the inner wall of the discharge vessel (1). Two current supply inlets are respectively melted into the two ends of the discharge vessel (1), with a helical electrode secured thereto (5). The invention is characterized in that in order to increase the switching resistance of the lamp in a cold start operation, at least one other electrode (7,8) made of a conductive material is arranged in the region between the helical electrode (5) and the connecting end of the discharge vessel (1) and one end of said other electrode (7, 8) is electrically connected to one of the two current supply inlets (3,4).
Abstract:

Abstract:
A discharge lamp having a tube-like envelope (1,3) comprising an electrode (4) near at least one of the two ends of the envelope. The axis (5) of the electrode (4) is directed substantially perpendicular to the axis of the tube-like envelope (1,3). The ends of two pinch lead wires (7) are connected to the ends of the electrode (4) and a portion (10) of each pinch lead wire (7) is embedded in the material of the envelope (1,3). The electrode (4) is located nearer to the end of the tube-like envelope (1,3) than a part of the pinch lead wire (7) that is embedded in the material of the envelope (3), resulting in a uniform light emission up to almost the end of the envelope.
