ABSTRACT:
A filtered lamp assembly useful for illuminating an aircraft cockpit instrument cluster. The lamp assembly includes an incandescent light bulb positioned within a housing that allows the emission of light having a wavelength in the range between about 380 and 620 nanometers. A wire form is positioned within the housing adjacent the light bulb and around the electrical leads extending from the light bulb so as to seal between the housing and the light bulb. The wire form prevents the leakage of a solidifable fluid material that is utilized to fix the light bulb and wire form into position. Further, a process for manufacturing a wire form minimizes the quantity of inventory and tooling necessary for the production of the filtered lamp assembly.
