Methods and apparatus are provided for increasing the luminous output of a fluorescent lamp suitable for use as a backlight in an avionics or other liquid crystal display (LCD). The apparatus includes a channel [108] configured confine a vaporous material that produces an ultra-violet light when electrically excited. A layer of light-emitting material [202] disposed ^ithin at least a portion of the channel is responsive to the ultra-violet light to produce the visible light emitted from the lamp [100]. To increase the luminous output of the lamp, the surface area of the light-emitting material is increased through the presence of one or more grooves [e.g. 402, 404]. The grooves may be longitudinal or transverse with respect to the channel. |
