Abstract: An assembly of light emitting diodes for a streetlight or the likes comprises a first board having a first matrix of light emitting diodes (LEDs) mounted thereon defining a first light projection plane and at least another board having a second matrix of LEDs mounted thereon defining a second light projection plane. The other boards are mounted to the first board so as to define an angle therebetween. The LEDs can be mounted to the boards so as to independently define and angle therewith. They can also be oriented towards privileged directions. The present assembly allows providing a more uniform light distribution.

Abstract: A system and method for controlling a matrix of light emitting diodes (LED) connected to an input line comprises a power converter for connecting to the matrix of LEDs and to the input line therebetween and for receiving from the input line an input current and an input voltage characterized by a shape and a frequency and for providing a direct current (D.C.) output for powering up the LEDs, yielding an operating current through the LEDs. The power converter includes a first current sensor for sensing the input current and a second current sensor for sensing the operating current. The system further comprises a controller for connecting to both the input line and to the power converter.
