Quantum dimming via sequential stepped modulation of LED arrays
摘要:
In one method of and apparatus for varying the luminosity of illumination, each of a plurality of light sources has an on state in which it emits light and an off state in which it does not emit light. Each of the plurality of light sources is switched cyclically between the on state and the off state in a sequence over a cycle period. The switching sequence is selected such that the number of said light sources that are on is uniform over the cycle. The luminosity of the illumination is varied by varying the proportion of each cycle for which each light source is switched on.
