Abstract
A method of controlling respective intensity levels of each of N light units, from a first light unit to an Nth light unit. Each of the light units has respective intensity levels from a 0 level to an L level based on duration of illumination of each light unit, In the method, a control signal representing light intensities for each of the N light units, sequentially, in order, for the first light unit to Nth light unit is received and processed. Then, the light units are re-arranged in accordance with the light intensities into a re-arranged order, from level L to level 0. A predetermined time period is counted sequentially through L time intervals. The light units are turned on in the re-arranged order at respective time intervals corresponding to the light intensities; and all light units are turned off at the end of the predetermined time period.
