  • Multiplexed ultra-low-power LED luminaire
    Patent number: 9357608
    Abstract: The present invention relates to a luminaire based on the same optical principle as the cinema, in which only one image is presented at any given instant of time but the image appears to be in constant movement. According to the invention, each LED lights up simultaneously for an instant of time in a sequential manner, as with television screens. The LED luminaire of the invention includes a configuration of electronic elements in a circuit which controls the lighting of the LED array and which also includes a PIC microcontroller, a CMOS multiplexer and an operational amplifier that can be used to improve the power consumption of the luminaire, lighting control and the lighting quality of the LED luminaire.
