DUAL LAYER LIGHT GUIDE STRUCTURE FOR LED BASED AMBILIGHT
摘要
A device for guiding and mixing light comprising of a light guide, at least a first set of light emitting elements in a first layer and at least a second set of light emitting elements in a second layer. Each of the light emitting elements being arranged to emit light of at least a first predetermined frequency. The second layer extending in a second geometrical plane different from a first geometrical plane of the first layer for producing a uniform light output from the aggregate of the constituting frequencies.
