Abstract: An LED-based lighting unit for retrofitting a fluorescent light fixture in a transit vehicle has a concave frame or structure conforming to the shape of the fluorescent lighting fixture cavity, connector pins on either end of the frame for secure attachment to sockets of the fluorescent fixture, a plurality of LED modules for illuminating an area of a transit vehicle, a power adapter for receiving and converting an input power supply signal, and a diffusive lens cover. The frame may have rear fins or other features for facilitating dissipation of heat generated by the LEDs. A controller adjusts the intensity of the LEDs based on a reading from a temperature sensor and on a manual brightness setting. The change in light output may be accomplished by reducing a duty cycle of a pulse width modulated (PWM) waveform supplying the LEDs.

Abstract: A lighted interior accessory assembly for a vehicle includes an interior accessory such as an armrest or console and a plurality of fasteners mounting the interior accessory on the interior panel. A mounting plate has a light pipe mounted thereon and emitting light along the length of the light pipe. The mounting plate is sandwiched between the armrest and the interior panel so that the mounting plate creates a gap between the armrest and the interior panel through which the light pipe emits light into the vehicle interior. Mounting the armrest directly to the door trim without inter-positioning the mounting plate between the armrest and the door trim eliminates the gap and eliminates the light pipe. Accordingly, a vehicle manufacturer can readily include a lighting feature in a luxury version of the vehicle and omit the lighting feature from a standard version of the vehicle.
