APPARATUS AND METHOD FOR CONTROLLING COLOUR AND COLOUR TEMPERATURE OF LIGHT GENERATED BY A DIGITALLY CONTROLLED LUMINAIRE |
摘要 |
<p>The present invention provides a method and apparatus for controlling the correlated colour temperature (CCT) or colour of light produced by an array of light-emitting elements by providing multiple selectable paths for the flow of drive current. The apparatus includes a primary path comprising primary light-emitting elements, and one or more secondary paths comprising secondary light-emitting elements that are used for compensation or correction of the colour of light emitted by the primary light-emitting elements. A plurality of control means, for example switches are used to direct current through particular paths. During operation, the drive current primarily flows through the primary light-emitting elements and is redirected, periodically for example, to a secondary path comprising light-emitting elements of a particular colour that is desired in addition to the colour produced by the primary light-emitting elements.</p> |
