Abstract

A LED lighting arrangement includes a support body having mounted thereon one or more LED lighting sources and a driver or feeding the LED lighting sources. The support body includes a high-voltage section carrying the driver and a low-voltage section carrying, mounted on a heat sink, the light sources. An insulation barrier is provided between the high voltage section and the low-voltage section of the board with a twisted pair forming a wiring that traverses the insulation barrier to connect the driver and the LED lighting sources.

Claims

1. A mounting arrangement for an LED lamp comprising:

a support body having mounted thereon at least one LED light source and a driver for feeding said at least one LED lighting source;

said support body having a high-voltage section carrying said driver and a low-voltage section carrying said at least one LED lighting source;

said low-voltage section including an electrically conductive heat sink on which said at least one LED light source is mounted, said heat sink being freely touchable during operation of said LED lamp;

an insulation barrier being provided between said high-voltage section and said low-voltage section of said body with a wiring traversing said insulation baffler to connect said driver and said at least one LED lighting source;

said high-voltage section having a protrusion that extends into a corresponding recess in said low-voltage section to produce a mating relationship between said sections; and

said insulation barrier being in the form of a cap that is mounted onto said protrusion and adapted to achieve a mechanical connection of said sections of said arrangement.

2. The arrangement of claim 1, wherein said driver includes a fly-back transformer with a floating secondary winding.

3. The arrangement of claim 1, wherein said wiring is in the form of a twisted pair.

4. The arrangement of claim 2, wherein said wiring connects said secondary winding to said at least one LED lighting source.
