Abstract
Abstract An illuminating device for providing illumination of any desired colour, intensity and saturation, which may be remotely controlled, comprises a housing of matte transluscent material, one or more groups of light sources disposed within the housing, each group including a red light source, a blue light source and a green light source and light dimmers for individually controlling the intensity of each of the light sources to thereby select the colour and intensity of illumination of the device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
An illuminating device for providing illumination of selectable substantially uniform intensity and colour at the exterior surface of a translucent body of rotation comprising: a housing of translucent material in the form of a body of rotation, said translucent material glowing in response to illumination thereof; a least three substantially identical clusters of light sources, the sources in each cluster including respectively the primary colours red, blue and green; said red, blue and green light sources in said clusters being disposed symmetrically about at least one axis of said housing in predetermined spaced relationship to said body of rotation to provide an unobstructed light path between substantially every point on the surface of said housing and at least one light source of each of said red, blue and green light sources thereby directly to illuminate substantially all points on said housing of translucent material from at least one of said light sources of each of the respective red, blue and green colours; and means for separately energizing the light sources of each colour to permit illumination of said housing in a multiplicity of selectable colour permutations.
Claim 2
Dependent Claim
186 words
An illuminating device for providing illumination of selectable substantially uniform intensity and colour at the exterior surface of a translucent body of rotation comprising: a housing of translucent material in the form of a body of rotation, said translucent material glowing in response to illumination thereof; a least three substantially identical clusters of light sources, the sources in each cluster including respectively the primary colours red, blue and green; said red, blue and green light sources in said clusters being disposed symmetrically about at least one axis of said housing in predetermined spaced relationship to said body of rotation to provide an unobstructed light path between substantially every point on the surface of said housing and at least one light source of each of said red, blue and green light sources thereby directly to illuminate substantially all points on said housing of translucent material from at least one of said light sources of each of the respective red, blue and green colours; and means for separately energizing the light sources of each colour to permit illumination of said housing in a multiplicity of selectable colour permutations.
Claim 3
Dependent Claim
43 words
An illuminating device according to claim 1 wherein said means for separately energizing the light sources of each coLour include means for separately controlling the intensity of the light sources of each colour to provide an increased number of selectable colours of illumination.
Claim 4
Dependent Claim
23 words
An illuminating device according to claim 1 and further including at least one white light source and means for controlling the energization thereof.
Claim 5
Dependent Claim
19 words
An illuminating device according to claim 3 wherein each cluster of light sources further includes a white light source.
Claim 6
Dependent Claim
18 words
An illuminating device according to claim 1 and further including means for remote control of light source energization.
Claim 7
Dependent Claim
21 words
An illuminating device according to claim 1 including three clusters of light sources disposed at approximately 120* orientation from each other.
