Example Embodiment

[0030] Reference will now be made in more detail to the preferred embodiments of the present invention. Examples of these preferred embodiments are shown in the attached Figure 5 to Figure 8 in. Wherever possible, the same reference numerals used in describing related technologies will be used throughout the drawings and the specification to refer to the same or similar parts.

[0031] Figure 5 It is a plan view showing the channel structure provided on the FFL plate of the hot-cold-hot flat fluorescent lamp according to the first embodiment of the present invention. As shown in the figure, in the heat-cold-heat type flat fluorescent lamp according to the first embodiment of the present invention, the channel structure is specially designed so that the width of the discharge channel 16 constituting the discharge space 12 of the lamp is along the opposite direction from the lamp. The direction from the end to the middle part of the lamp forming the cold zone gradually decreases, ...

Abstract

A channel structure of a flat fluorescent lamp is disclosed. The channel structure of the flat fluorescent lamp is configured such that the lamp is suitable for being used as a backlight unit for flat displays, such as LCDs, or as a widerange light source to evenly illuminate wide flat surfaces, such as wide rectangular surfaces. In the channel structure of the flat fluorescent lamp, a sealed discharge space having a continuous serpentine shape and being partitioned into a plurality of communicating discharge channels by a plurality of partition walls is defined, with one or more electrodes provided in the discharge space. The discharge channels have different widths which are reduced in a direction away from a hot electrode.

Description

technical field [0001] The present invention relates generally to channel structures for flat fluorescent lamps, and more particularly to a channel structure constructed such that such lamps are suitable for use as backlight units for flat-panel displays such as liquid crystal displays (LCDs) or as devices for uniformly illuminating wide Channel structure of a flat fluorescent lamp for a wide range of light sources on a flat surface (such as a wide rectangular surface). Background technique [0002] LCDs, which are most widely and preferably used as flat-panel displays in image display devices, are non-emissive displays that do not emit light by themselves and are generally called "light-receiving displays", unlike conventional emissive displays that emit light by themselves, Examples include cathode ray tubes (CRTs), plasma display panels (PDPs), field emission displays (FEDs), and light emitting diodes (LEDs). Thus, when the LCD is not backlit by a separate light device, ...
