Abstract
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.
