Переведите текст. energy consumed by the electrical lighting system can be saved by installing better light emitting technology, better control systems (occupancy and daylight dependent dimming) and a possibility for a control of the light depending on the location within the room – near the windows or far from the windows – so-called zoning. often this is done as one package as the marginal costs for including the control and zoning is rather limited when a new lighting system is installed. in the calculations a complete package is therefore analysed. the efficient lighting systems considered are new light tubes – t5, compact fluorescent light (cfl) and led lamps. controls are manual, continuous dimming and 2 zones versus one in the reference case have been analysed.
