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.
An LED wedge-based lamp and method of making the lamp, where the lamp has a generally planar circuit board having one end that has electrical connections exposed thereon and a connecting part that is adapted to mechanically couple the lamp to a wedge-based lamp socket. The lamp includes an LED light engine near a second end of the circuit board, where the light engine includes plural laterally aligned LEDs whose light output mimics the light output of an incandescent lamp, such as used in automobile stop and turn signals. The lamp includes a load resistor, whose load mimics that of the incandescent lamp, on an exterior surface of the connecting part. The connecting part may be a sleeve that slides onto the circuit board. A hand grip/heat sink may be provided at the second end of the circuit board.

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.
