International Classification:

F21V 7/04

US Classification:

362541, 362543, 362545, 362549

Abstract:

A light source system is arranged about an axis, and includes a planar member having top and bottom surfaces with a central aperture and a plurality of electrical conductors spaced about the central aperture and extending beyond the top and bottom surfaces. A portion of the electrical conductors extending beyond the top surface have electrical insulators. A base having passages to receive the electrical conductors extends beyond the bottom surface and includes a boss on the top surface fitted through the aperture. A body has a first part coaxial with the axis and a second part transverse to the axis. A light source is positioned near an end of the first part. The base is positioned at an opposite end of the body and a plurality of rod-like members project from the second part parallel to the axis; and a light emitting diode is positioned adjacent the first part.

Abstract:

An method of operating a neon stop lamp for a vehicle is described. By adjusting the lamp pressure, the then controlling the frequency and pulse width of the power, the lamp efficiency can be increased, while also shifting the chromaticity for the lamp to comply with automotive standards. The result is a small, efficient light source whose light may be reflected and focused, and whose color is correct for vehicle warning lights.
