  • Publication number: 20050157492
    Abstract: A lighting device has a body for holding a battery cell and a connected head that has a lens having several light deflecting portions. A number of light sources, such as super LEDs, are mounted within the head for energization by the battery cell to emit light through the lens, with light from the individual light sources being merged together by the light deflecting portions. A switch on the body switches on and off the light sources. The light sources comprise two groups of different colours. The head is rotatable relative to the light sources for aligning the light deflecting lens portions with the light sources of either one group selectively for merging the light of the corresponding colour from that group.
