An electrical interface module (EIM) is provided between an LED illumination device and a light fixture. The EIM includes an arrangement of contacts that are adapted to be coupled to an LED illumination device and a second arrangement of contacts that are adapted to be coupled to the light fixture and may include a power converter. Additionally, an LED selection module may be included to selectively turn on or off LEDs. A communication port may be included to transmit information associated with the LED illumination device, such as identification, indication of lifetime, flux, etc. The lifetime of the LED illumination device may be measured and communicated, e.g., by an RF signal, IR signal, wired signal or by controlling the light output of the LED illumination device. An optic that is replaceably mounted to the LED illumination device may include, e.g., a flux sensor that is connected to the electrical interface.

A lighting device for a vehicle may include a light source; a lens; and a first reflecting unit provided on a partial area of a front surface of the lens. The lighting device may also include a light reducer configured to reduce a size of light emitted from the light source and to emit light having a reduced size toward the first reflecting unit on the lens. The lighting device may further include a reflective fluorescent body disposed on a rear side of the lens and configured to convert a wavelength of light reflected from the first reflecting unit and to reflect light having a converted wavelength into the lens.

A light fixture includes a light source, a wavelength-conversion material, and a reflector. The light source is configured to emit a first radiation, and has a front surface and a back surface. The wavelength-conversion material is arranged under the front surface and configured to convert the first radiation to a second radiation which has a first portion not able to reach the reflector and a second portion able to reach the reflector. The reflector is arranged over the back surface and configured to reflect the second portion away from the light source without passing through the wavelength-conversion material. The reflector has an end distant from the light source and is arranged in an elevation different from that of the wavelength-conversion material.
