This specification covers the general requirements for integrally illuminated information panels.

Classification:

The panels shall be furnished in the following types and classes as specified (see 6.2).

Classes:

Class 1-R. Panels having the background of the front face of the panel finished with black and the integral illumination of Instrument and Panel Lighting (IPL) - Red.

Class 1-W. Panels having the background of the front face of the panel finished with black and the integral illumination of Instrument and Panel Lighting (IPL) - White

Class 1-BW. Panels having the background of the front face of the panel finished with black and the integral illumination of (USAF) Blue-Filtered White.

Class 1-NVIS Green A. Panels having the background of the front face of the panel finished with black and the integral illumination meeting the Class A NVIS compatible lighting requirements of MIL-L-85762 is NVIS Green A.

Class 2-R. Panels having the background of the front face of the panel finished with gray and and the integral illumination of Instrument and Panel Lighting (IPL) - Red.

Class 2-W. Panels having the background of the front face of the panel finished with gray and the integral illumination of Instrument and Panel Lighting (IPL) - White.

Class 2-BW. Panels having the background of the front face of the panel finished with gray and the integral illumination of (USAF) Blue-Filtered White.

Types:

Type III - One piece plastic panels. Panels consisting of one sheet of plastic utilizing MS25237 lamps in MS25010 light assemblies for illumination.

NOTE: Type III panels shall be inactive for new design. Qualification for Type III panels shall be determined by qualification for Types IV or V. Type III panels may be updated to Types IV or V by the use of adapter plug MS90335-9 (see 6.8).

Type IV - One piece integrally wired incandescent panels. Panels consisting of one sheet of plastic using MS24367, MS90451, or MS90452 lamps and wiring embedded within the panel.

Type V - Printed circuit board panels. Panels consisting of one sheet of plastic with MS24367, MS24515, MS90451, or MS90452 lamps soldered to a removeable printed circuit board that is recessed so that the circuit board is flush with the back of the plastic panel. The filter element is an integral part of the plastic panel whereas the lamp is an integral part of the circuit board. When specified by the procuring activity, an alternate approach may use these lamps in a based configuration and with T1 or T1 3/4 front relampable light assemblies (see 3.4.3.4.1).

Type VI - Electroluminescent panels. Panels consisting of one sheet of plastic with encapsulated electroluminescent lamps or a combination of electroluminescent lamps.

Type VII - Light emitting diode (LED) panels. Panels consisting of LEDs soldered to a removable printed circuit board recessed so that the circuit board is flush with the back of the plastic panel.
