1328419 Ornamental decorative light devices CHIYODA KK 16 Aug 1971 38347/71 Heading F4R [Also in Division C4] For use for decorative or personal ornamental purposes at least one light emissive diode LED has a socket 21, Fig. 2B, connected to its terminals 1, 1<SP>1</SP> through a "decorative member" 3 such as jewellery, garment or display panel, the socket terminals 23, 23<SP>1</SP> in turn being connected via switch S to an energizing power source PS. The garment, jewellery or other support 3 is trapped between the LED and the socket 2, Fig. 1A, to mount the devices. The LED may be embedded in a transparent member 6 which is faceted to enhance the ornamental effect. The light output from different devices may be of different colour. The switch S may be manually controlled and built into the housing containing the mercury-battery power source, Figs. 2E and 2F (not shown). Alternatively groups of associated LED devices may be serially or randomly energized, thus the movement of the wings of a butterfly in flight may be simulated. In a further embodiment a series of band-pass amplifiers, Figs. 7 and 8 (not shown), arranged so that their band-pass frequencies divide the audio-frequency into a series of bands are arranged to switch on and off corresponding LED device groups in response to stereophonic music picked up by a microphone. These devices may be mounted on a wall and the frequency spectrum of the music may synchronize with the colours flashed. The luminance of each LED can also be changed according to the intensity of the frequency spectrum.
