An electric light has a semiconductor 2, for example an LED, mounted to a base 6 at least partly surrounded by a liquid container 18, with is filled with liquid 22 such that the liquid 22 is in thermal conducting path with the liquid container 18 and the base 6, to cool the semiconductor 2 in use. Light emitted from the semiconductor 2 passes through the liquid 22. The base 6 contains an electronic ballast 16 between supply contacts 8 and semiconductor 2. The outer surface of the container 12 may have a Fresnel pattern (fig 3) or may be curved (fig 2). |
