A method of manufacturing an LED lighting assembly, the method comprising:
- preparing a flexible carrier for a number of light-emitting diodes;
- mounting the light-emitting diodes onto the flexible carrier;
- providing a flexible shaping element made of a material that can be bent into a desired shape or form and comprising a heat spreader;
- winding a wire coil around a supporting element of flexible material such that the wire coil can dissipate heat from the light-emitting diodes during operation;
- and
- winding the flexible carrier about the flexible shaping element in a helical manner.
An LED lighting assembly comprising:
- a flexible shaping element made of a material that can be bent into a desired shape or form, the flexible shaping element comprising a longitudinal supporting element and a wire coil wrapped around the longitudinal support element, and the flexible shaping element further comprising a heat spreader;
- and
- a number of light-emitting diodes mounted onto a flexible carrier, the flexible carrier being wound in a helical manner about the flexible shaping element.
An LED lighting unit comprising:
- an LED lighting assembly arranged in a container,
- the LED lighting assembly comprising a flexible shaping element made of a material that can be bent into a desired shape or form, the flexible shaping element comprising a longitudinal supporting element and a wire coil wrapped around the longitudinal support element, and the flexible shaping element further comprising a heat spreader;
- a number of light-emitting diodes mounted onto a flexible carrier,
- the flexible carrier is being wound in a helical manner about the flexible shaping element, and
- the container comprising a number of partially reflective side walls and a light exit opening defined by the side walls, and the LED lighting assembly being embedded in a translucent flexible material.
