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 is 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. An electrode assembly that electrically excites the vaporous material includes a first post, a second post, a conductive filament suspended between the first post and the second post and having a tail portion extending therebeyond, and a benign insulating material such as glass frit substantially covering the tail portion to prevent radio frequency (RF) emissions from the tail portion of the filament.
A fluorescent light source for providing a visible light, the light source comprising:
An electrode assembly for insertion into a fluorescent light source for providing a visible light, the light source comprising a light-emitting channel configured confine a vaporous material that produces an ultra-violet light when electrically excited and a layer of light-emitting phosphor material disposed within at least a portion of the channel that is responsive to the ultra-violet light to produce the visible light, wherein the electrode assembly comprises a pair of electrode posts having a conductive filament suspended therebetween and having a tail portion extending outwardly from at least one of the electrode posts, and further comprising a benign insulating material substantially disposed over the tail portion.
A method of assembling a fluorescent light source, the method comprising the steps of:
