Abstract

The present invention relates to a lighting system comprising light emitting diodes (LEDs) wherein the LEDs are operated at high voltages. Specifically, the present invention provides a lighting system comprising: a power supply unit having an input connected to a mains network, and an output providing a rectified voltage; a carrier comprising a first layer, which is substantially electrically isolating, and a second layer, which is electrically conducting and non-floating; a lighting group comprising a plurality of serially connected light emitting diodes (LEDs) connected to said power supply and mounted to said first layer of said carrier; wherein said first layer has a critical electric field substantially larger than the root mean square voltage of said mains network divided by the smallest distance between any of said LEDs and said second layer.
