Abstract:
1. A method of controlling respective light intensity levels of each of N light units, from a first light unit to an Nth light unit, each of the light units producing light at a plurality of controllable intensity levels, the intensity levels ranging from a lowest level, 0, to a highest level, L, based on duration of illumination of the respective light units, the method comprising: receiving and processing a control signal including a respective light intensity level for each of the N light units, sequentially, in an order from the first light unit to the Nth light unit; re-arranging the respective light intensity levels of the N light units, of the control signal that has been processed, in accordance with the light intensity levels, in a re-arranged order, from the highest light intensity level to the lowest light intensity level; counting a predetermined time period sequentially through L time intervals; turning on the respective light units in the re-arranged order at respective time intervals corresponding to the respective light intensity levels; and turning off all of the light units at the end of the predetermined time period.
