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.

A lamp, a method of driving the lamp, a backlight assembly having the lamp, and a liquid crystal display (LCD) device having the backlight assembly are disclosed. The lamp includes a tube that contains gas and first through fourth electrodes. The first and second electrodes are disposed in the tube adjacent to first and second ends of the tube. The third and fourth electrodes are disposed at the first and second ends of the tube. Voltages applied to the electrodes are sufficient for light to be emitted throughout the lamp. The first and second voltages, third and fourth voltages, first and third voltages, and second and fourth voltages have different polarities while the first and fourth voltages and the second and third voltages have the same polarity.

An electrical illumination device for generating saturated colors with at least two illumination units, the illumination units each having a discharge vessel with a low-pressure discharge and a phosphor coating on the inner wall of the vessel, characterized in that at least one illumination unit has a discharge vessel with a xenon fill and a dielectric barrier discharge (R, G, B).
Abstract:
An illumination control device for illuminating an light modulation information display device with light includes: at least one illumination device for irradiating light which is generated through discharging; and a driving waveform generation section for controlling the light which is irradiated from the at least one illumination device to the light modulation information display device. The light modulation information display device is operable so as to have a first period and a second period during which an image is displayed. During the first period, the driving waveform generation section applies a first voltage to the at least one illumination device, the first voltage causing the at least one illumination device to be turned entirely-ON. During the second period, the driving waveform generation section applies a second voltage to at least a portion of the at least one illumination device.

Abstract:
A compact lamp unit is described which functions both as a fluorescent lamp and as a nightlight. The lamp unit includes a housing, a fluorescent tube, a low power light source, a conductive base and first and second circuits. The housing is used to contain a number of components and to support the fluorescent tube and low power light source. The conductive base is attached to a neck portion of the housing and has contact terminals adapted for a three-way lamp socket. The first circuit is electrically connected between the fluorescent tube and two of the contact terminals to drive the fluorescent tube. The second circuit is electrically connected between the low power light source and two of the contact terminals to drive the low power light source.
