Miniature Lamps for Avionics


For avionics displays and other types of critical information displays

LCDL miniature lamps are typically a multiple bend lamp configuration used to backlight a Liquid Crystal Display (LCD). A laptop computer screen is the best known common example of an LCD display. Displays similar to this are used throughout industry to show information or present images for entertainment. Miniature lamps can be placed on the edge of an LCD display or directly behind it with a backplate to reflect illumination through the LCD. The application and use environment help determine the lamp's shape, size and power. Typically miniature lamps are multi-bend in shape and are usually from 6mm to 18mm in outside diameter (O.D.).

LCDL miniature lamps replace multiple lamp designs with more efficient, single lamp systems which produce a number of important benefits - simplified wiring harnesses, reduced power requirements and enhanced durability. LCDL can also provide value added services to further reduce the cost of your unit. (See Lamp Sub-Assemblies)

Most of the miniature lamps LCDL manufactures are used to illuminate very critical data displays - the avionics displays on nearly all the world's commercial, private and military aircraft. A portion of LCDL miniature lamps can also be found in laptops, ATM's, medical monitors, kiosk displays, or as OEM replacement lamps for similar devices.

LCDL offers lamps in the following shapes:

  • Grid Lamps -
    have more than one "U" bend in one plane. Electrode legs may be in the same plane, a parallel plane, or at right angles to the plane of the grid.

  • Circular Lamps -
    may be circular or oval in almost any size. The electrode legs may be parallel to the plane of the circle or in a plane at a right angle to the plane of the circle.

  • Interlocking Lamps -
    are for applications requiring redundancy, more than one lamp is used so that the display continues to be illuminated if one lamp fails. The lamps are designed to interlock; i.e., overlap in the same plane to provide optimum uniformity of light.
  • Custom Lamps -
    Do you have a different lamp shape in mind? Let LCDL know what you want. and we will be happy to work with you to make it a reality.

Readily available colors include: cool white, warm white, daylight, blue, green, red, and tri-band. Ultraviolet and infrared phosphors can also be supplied.
