Abstract:
Methods and apparatus are provided for increasing the life of a fluorescent lamp suitable for use as a backlight in an avionics or other liquid crystal display (LCD). The apparatus includes a channel configured confine a vaporous material that produces an ultra-violet light when electrically excited. A layer of light-emitting material disposed within at least a portion of the channel is responsive to the ultra-violet light to produce the visible light emitted from the lamp. To increase the lifespan of the lamp, a protective coating is provided on the layer of light-emitting material. The protective coating comprises a material that is transparent to both ultra-violet and visible light, yet is capable of filling even small gaps in the light-emitting material. In lamps wherein the vaporous material comprises mercury and the light-emitting material comprises a phosphorescent material, for example, the protective material may comprise fused silica (i.e. silica dioxide or "quartz glass").
Abstract:
An electric lamp has a light-transmitting lamp vessel (1) with a curved vessel portion (11) accommodating an elongated light source (2). Part of the curved vessel portion (11) is provided with an optical interference film (5) of which the thickness differs locally. The interference film (5) is thicker at locations on the curved vessel portion (11) substantially parallel to the source axis (22) as compared to other locations on the curved vessel portion (11). A method of depositing a layer (5) of a material on a such an electric lamp, includes the steps of : moving the lamp vessel (1) past sources of deposition material while simultaneously rotating the lamp vessel (1) along its vessel axis, locally shielding the lamp vessel (1) to locally reduce the thickness of the deposited material on the lamp vessel (1), the shielding means (55,56) being provided in the vicinity of the lamp vessel (1) and rotating at substantially the same speed as the lamp vessel (1).

Abstract:
A composition and method of forming an enhanced internal neutral density filter on a luminescent screen assembly of a cathode ray tube (CRT) is disclosed. The luminescent screen assembly is formed on an interior surface of a glass faceplate panel of the CRT tube. The luminescent screen assembly includes a patterned light-absorbing matrix that defines three sets of fields corresponding to one of a blue region, a green region and a red region. An enhanced internal neutral density filter is formed on the light-absorbing matrix. An array of blue, green and red color phosphors is formed on the internal neutral density filter corresponding to one of the blue region, the green region and the red region defined in the light-absorbing matrix. The enhanced internal neutral density filter has a composition including a red pigment, a blue pigment, one or more surface active agents and at least one non-pigmented oxide particle. The enhanced internal neutral density filter preferably has the surface active agent in the amount of about 0.7 to 1.2 weight % based upon the total mass in the filter.
