LIGHT-SENSING DEVICE FOR INFORMING LIGHT-GENERATING DEVICE |
摘要 |
First, light-sensing devices (1) comprise sensors (11) for sensing light (3) originating from second, light-generating devices (2) and for generating sensing results and comprise generators (12) for generating information (4) in response to the sensing results and comprise transmitters (13) for wirelessly transmitting the information (4) to the second devices (2). The second devices (2) comprise lightsources (21) for generating the light (3) and comprise drivers (22) for driving the light sources (21) and comprise receivers (23) for wirelessly receiving the information (4) for adapting the driving of the light sources (21). The first devices (1) may be self-powered devices and may comprise converters (31) for converting the light (3) for feeding the first devices (1). The light sources (21) may comprise one or more light emitting diodes. |
