A light source has a generally globular envelope with part spherical end portion 17, a cylindrical central portion 13, and mount portion 14 supported on a cap for releasable attachment to a lamp-holder. The end portion 17 can be formed separately from the central and mount portions 13 and 14 and snap fitted thereto. The envelope has a plurality of apertures and a like plurality of individual light emitting diodes (LEDs) 18 are mounted one in each aperture, to direct light out of the envelope. A pair of interconnected control circuit boards 24, 25 is arranged within the envelope and electrically connected to the contacts 28 of the cap as well as to the LEDs 18 such that all the LEDs will be illuminated when current is supplied to a lamp-holder carrying the light source. |
