摘要： A driver circuit provides a drive current from a power source to an arc lamp to produce a light. The circuit includes a transformer having primary and secondary windings, with the ends of the secondary winding providing the lamp drive current to the arc lamp. A current steering module provides a drive output from the power source to the transformer in response to a current steering input, and a current control loop adjusts the current steering input in response to the current in one of the windings of the transformer. A luminance control loop adjusts the current steering input in response to the brightness of the light and a luminance command. A power control module may be further provided to generate a boost command in response to a difference between the brightness of the arc lamp and a luminance command.

摘要： An anti-exponential amplifier produces an output signal that is an exponential/anti-logarithmic function of an input signal. The amplifier includes three function generators and a low-pass filter. The first function generator produces a periodic exponential waveform based upon a resistor-capacitor time constant, with the magnitude of the periodic exponential waveform exponentially increasing to a maximum value in each period. A second function generator produces a ramp waveform from the exponential waveform. The ramp waveform has a period and maximum amplitude substantially equal to those of the exponential signal. The third function generator produces a hybrid waveform with a first portion and a second portion, with the duration of the first period determined in response to the ramp waveform. A low pass filter produces the anti-logarithmic output signal as a function of the hybrid waveform. The resulting amplifier could be useful in a brightness or other parameter control for a display.

摘要： An assembly for heating a fluorescent lamp (such as the lamp used in a flat panel display) includes a circuit card having a plurality of transistors each configured to produce heat disposed thereon. A thermally-conductive layer is disposed proximate to the plurality of transistors, and the fluorescent lamp is disposed proximate the thermally-conductive layer such that the heat from the transistors is transmitted to the fluorescent lamp via the thermally conductive layer. By controlling the heat applied to the fluorescent lamp, microclimates in the lamp can be reduced or eliminated, thereby improving the performance of the lamp.

摘要： A lamp driver system is provided that facilitates improved efficiency and brightness control for an optical display system. The lamp driver system provides this improved efficiency and brightness control through the precise control of the plasma in the lamp. The lamp driver system excites the electrons in the plasma such that their obtained velocity is optimized to increase the probability of collision with the mercury atoms in the lamp. Collisions with mercury atoms release ultra-violet photons, which in turn excites the phosphor coating in the lamp. The resulting relaxation of the phosphor atoms releases photons in the visible spectrum, thus providing light with the required frequency components to illuminate the display.

摘要： 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”).

摘要： Methods and apparatus are provided for identifying the presence of leaks in a fluorescent bulb or other lamp suitable for use as a backlight in an avionics or other liquid crystal display (LCD). The lamp is first placed in a bath of helium or another vaporous substance having relatively small molecular size. The vaporous material is allowed to permeate through any leaks that may exist in the lamp and to thereby intermix with the light-producing vaporous material contained within the channel of the lamp. The lamp is removed from the bath and subsequently operated (e.g. at a low intensity), and the output electrical or optical characteristics of the lamp under test are obtained. If the output characteristics of the lamp under test substantially correspond to characteristics obtained from a lamp that is known to be in proper working order, then the absence of leaks in the lamp under test can be presumed.
