Abstract (en)
[origin: WO9727576A1] A retrofit lighting system (100), for use with a host machine (104), produces lighting effects in response to lamp power signals that are provided from the host system (104) and that would otherwise be used to power lamps (108) of the host machine (104). An EL lamp system (108) has a plurality of EL lamp cells. Sequencing circuitry (106) provides an EL lamp driving signal to independently control each of the EL lamp cells of the EL lamp system (108) such that the EL lamp cells collectively illuminate in a sequence corresponding to the EL lamp driving signal. The microcontroller (406) controls the frequency, amplitude, and duty cycle to the electroluminescent lamps (108). By changing the frequency, the microcontroller (406) alters the intensity and illumination color. By changing the amplitude, the microcontroller (406) alters the illumination intensity. Further, data signal lines are supplied from the microcontroller (406) to select which electroluminescent lamps (108) to illuminate, thereby creating animated displays. Signal conditioning circuitry (102) non-invasively samples the lamp power signals provided from the host system (104), and provides the driving signal to the EL lamp (108) in response thereto.
