Abstract:
The present invention relates to a discharge vessel (1) with at least one end part (2) and a discharge cavity (3), whereby at less one coating layer (4) is located and gas-light connected between the end part (2) and a a sealant (5) or between the sealant (5) and an end closure member (9), the discharge vessel (1) preferably being least partly coated with said coating layer (4) and the gas-tight bonding of the coating layer to the discharge vessel (1), to a sealant (5) and/or to an end closure member (9) is stronger compared to the direct gas-tight bonding of said sealant (5) to said end closure member (9) or discharge vessel (1).
Abstract:
A method for manufacturing a light-emitting panel sandwiches a plurality of micro-components between two flexible substrates in a web configuration. Each micro-component contains a gas or gas-mixture capable of ionization when a sufficiently large voltage is supplied across the micro-component via at least two electrodes. The micro-components are disposed in sockets formed at pre-determined locations in a first dielectric substrate so that they are adjacent to electrodes imprinted in the first substrate. Dielectric layers and the conductors for acting as electrodes are formed using liquid processes or combined liquid and sheet processes, where liquid materials are applied to the surface of the underlying layer, then cured to complete the formation of layers. The assembled layers are coated with a protective coating and may include an RF shield. In one embodiment, patterning of the conductors is achieved by applying conductive ink using an ink jet process. In another embodiment, the conductors may be patterned photolithographically using a leaky optical waveguide as a contact mask.
Abstract:
The invention relates to a lamp that radiates visible light and infrared light. According to the invention, the lamp bulb (4) of the lamp comprises at least a first region (6) which is at least partly permeable to infrared light and at least partly impermeable to visible light, and at least a second region (9) which is wholly or partly permeable at least to visible light.
Abstract:
A light-emitting device is provided with getter material (58) that can readily be distributed in a relatively uniform manner across the device's active light-emitting portion. An electron-emitting device is similarly provided with getter material (112, 110/112, 128, 132, and 142) that can readily be distributed relatively uniformly across the active electron-emitting portion of the device. Techniques such as thermal spraying, angled physical deposition, and maskless electrophoretic/dielectrophoretic deposition can be utilized in depositing the getter material.
Abstract:
The invention relates to a lamp, particularly a high-pressure discharge lamp, comprising a base (24), whereby an upper electric connection (28b) is contacted by a return conductor (27) running along a lamp body (14), and to a method for producing a lamp of this type. According to the invention, the return conductor (27) is provided by a conducting layer (17), which is applied using vacuum technology, in particular, sputtering and which is directly located on the lamp body (14). This results in reducing manufacturing costs associated with the mounting of an isolated return conductor (27) running parallel to the lamp body (14). In addition, the lamp produced in the aforementioned manner reliably functions by virtue of the fact that the conducting layer (17) is not affected by vibrations. This lamp can be used, for example, for headlamps of a motor vehicle.
Abstract:
An electric lamp is disclosed comprising a light-transmitting lamp vessel 1 which accommodates a light source 2. At least a part of the lamp vessel 1 is provided with a light-absorbing coating 3, the light-absorbing coating comprising stabilized pigments which are incorporated in a sol-gel matrix. In order to stabilize the pigments, an aminosilane is present. Moreover, a lamp vessel 1 fit for an electric lamp is disclosed, as well as a method of preparing a light-absorbing layer to be applied to the lamp vessel of an electric lamp.
Abstract:
The inventive method relates to microelectronic and consists in the application of an emission layer to elements of an addressable field-emission electrode with the aid of a gas-phase synthesis method in a hydrogen flow accompanied by a supply of a carbonaceous gas. A dielectric backing is made of a high-temperature resistant metal. The growth rate of the emission layer on the dielectric backing is smaller than the growth rate of the emission layer on the metallic discrete elements as a result of a selected process of depositing the carbonaceous emission layer. For producing a display structure, a control grid is obtained from the metal layer having an emission threshold higher than a field density at which the cathode emits the required current. The inventive method enables to avoid operations of removing the emission layer making it possible to produce flat displays having high characteristics in addition to high performance and low cost.
Abstract:
The invention relates to a method for applying a coating (23) to a part of a surface of a lamp (20). The aim of the invention is to provide a simple means of applying exact coatings to parts of surfaces with complicated designs. To this end, the invention provides that the lamp is vacuum-coated. The parts of the surface of the lamp (20) that are not to be coated are covered by a mask (3) and at least one coat is applied to the non-covered parts of the surface. Said mask (3) is located at a predetermined distance (d) from the part of the surface of the lamp (20) and said mask (3) is oriented in relation to an illumination means (2) or a base (21) of the lamp (20). The invention also relates to a coated lamp that is produced according to a method of this type.
Abstract:
The invention relates to a device (10) for applying a thin coat consisting of a fluid coating medium on the curved surface (12) of a screen of a cathode-ray tube (11). Said device comprises a rotary table (20) that can be driven rotationally. The rotary table also includes a location (30) for the object (11) to be coated to fix said object in such a way that it cannot rotate and a processing tank (50) surrounding the location (30) and the rotary table (20) that is locked to prevent turning. A first annular gap is provided between the spray ring (60) and the upper part (51) of the processing tank (50) while the location (30) is fitted with a suction cone (32). A second annular gap (37) is formed between said cone and an outer wall of the processing tank (50). An annealing chamber (36) is formed inside said second annular gap. A laminar flow (A) is directed towards the spray ring (60) or the upper part of the processing tank (50). The bottom (54) of the processing tank (50) is connected to a suction device (B).
