A light constructed from two basic elements, the first being a printed circuit board 1 on one side of which is mounted LEDs 2, the second being a moulded plastic cover part 5 that covers the circuit board 1 and is shaped to have integral optical elements e.g. lenses 6. The circuit board 1 may have other circuit elements for sensing or control. The circuit board 1 may serve as a heat sink. A bezel 9 may be fitted on the cover 5 to support other optical elements, e.g.filters, screens 8,10. |
