Light module having a heatsink crimped around a lens, and a method for crimping a heat sink around a lens of a light module

A method for lighting, comprising:

• providing a lens for covering a printed circuit board having at least one light emitting diode, the lens forming an arc in a lateral cross-section, the lens including at least two first edges at the ends of the arc, the arc spanning at least a width of the printed circuit board and defining a space between the lens and the printed circuit board, the lens extending along the at least two first edges substantially a length of the printed circuit board;
• providing a heatsink adapted to couple to the printed circuit board, the heatsink extending substantially the width and the length of the printed circuit board, the heatsink including at least two second edges along the length of the printed circuit board;
• positioning at least one of the first edges of the lens in at least one channel on at least one of the second edges of the heatsink;
• and
• crimping the at least one channel.
