Miniature Backlight Lamps for Computers

Typical backlight for a computer
LCD Lighting manufactures miniature backlight lamps (CCFL) for liquid crystal displays (LCD) in laptop computer screens. Most computer screens are lit with built-in fluorescent tubes above, beside and sometimes behind the LCD. A white diffusion panel behind the LCD redirects and scatters the light evenly to ensure a uniform display, which is known as a backlight.

In general, miniature lamps are multi-bend in shape and are 2mm to 18mm in outside diameter (O.D.). LCD Lighting miniature lamps can replace multiple lamp designs with more efficient, single-lamp systems. These single-lamp systems provide a number of important benefits, including simplified wiring harnesses, reduced power requirements and enhanced durability.
