摘要： A direct backlight apparatus for a Liquid Crystal Display (LCD) panel includes a lamp housing and a lamp. The lamp housing accommodates a support structure disposed on the bottom of the lamp housing wherein an open end is defined by one side of the lamp housing. The lamp, supported by the support structure, is installed in the lamp housing and is further attached to a holding structure at one end of the lamp, for holding the lamp. The lamp is removed from the lamp housing through the open end by moving along a direction of the support structure when a force is exerted on the holding structure.

摘要： A reflector for each of linear light sources arranged in parallel at predetermined intervals. The reflector includes a reflective region formed symmetrically about each light source. In one half part of symmetry, the reflective region comprises three reflective surfaces including a reflective surface close to the light source, an intermediate reflective surface, and a reflective surface distant from the light source. The reflective surface close to the light source is formed to have a flat horizontal reflective surface to reflect light back to a relatively wide range of a surface to be illuminated. The intermediate reflective region is formed to have a reflective surface slanted to the horizontal reflective surface or a curved reflective surface concavely curved thereto so as to have reflected light overlapped with reflected light illuminating in the wide range of the surface to be illuminated. The reflective region distant from the light source is formed to have a reflective surface slanted to the horizontal reflective surface so as to have reflected light overlapped with reflected light illuminating in the wide range of the surface to be illuminated.

摘要： The present invention discloses a backlight including external electrode fluorescent lamps and a method for driving the backlight. The backlight includes fluorescent lamps having external electrodes made of an electrically conductive material for wrapping the outer peripheral surfaces including edge cross-sections on both ends of a glass tube with a layer of fluorescent substance applied thereon. The backlight is constructed in a manner that a plurality of such fluorescent lamps are installed at the outer portions of a plastic light guide, and an alternating current type power source is applied from the outside to the fluorescent lamps by installing a plurality of the fluorescent lamps between a reflecting plate and a diffusing plate and electrically connecting them with one another. The backlight of the present invention is driven by a square wave from a switching inverter, and is characterized by the use of an overshooting waveform and a self-discharge effect favorable to an initial discharge, thereby driving it using a low frequency of several dozen kHz and thus realizing high luminance and high efficiency.
