SMART POWER SUPPLY FOR LED LIGHTING SYSTEMS WITH INTEGRATED LIGHT AND PRESENCE SENSORS AND COMMUNICATION BY VISIBLE LIGHT AND POWER LINE.

摘要

The invention relates to an intelligent power supply for LED lighting systems, with integrated light and presence sensors, and power line and visible light communication. In addition to a power stage (8), the intelligent power supply comprises: light (2) and motion (9) sensors connected externally; and, internally, a microprocessor (4), a variable gain amplifier (3) at which the signal from the light sensor (2) enters, which controls the microprocessor (4), and a very-low-frequency low-pass filter (6), at which the amplified signal (5) arrives and which eliminates all electrical noise, as well as, for programming and configuring the supply (1), a micro-outage detector (12) and a micro-consumption generator (13) for receiving data, and a macro-outage detector (14) for programming. The invention also includes a local power supply (10) which maintains the microprocessor (4) active in all situations in which the power stage (8) is switched off.
