Device for controlling the transmission of light from light sources

Device for controlling the transmission of light from light sources

The envelope (6) of a light source is at least partly coated with electrochromic material (20), sandwiched between two conductive layers (21,22). A voltage applied to the electrochromic material by way of the conductive layers varies the intensity and/or color of the light from the source.
