为照明解决方案增加智能和灵活性
照明是大多数人习以为常的一种舒适。简单地翻转开关的能力——不考虑灯泡背后的技术——是照明工程师所不具备的奢侈品。目前，照明约占全球电力消耗量的四分之一，发达国家正在通过“绿色”立法，以减少能源消耗，减少对环境的关注。随着照明越来越受到重视，照明工程师需要利用传统白炽灯的高效照明替代品。
当今最高效的照明替代品的前沿是LED和紧凑型荧光灯（CFL）技术。事实上，后者已经有将近20年但最近业界一直无法摆脱的坏名声，早期的节能灯已获得。在疯狂的最初抢购产品到消费者手中，并以最低的成本，紧凑型荧光灯制造商削减了许多角落，最终牺牲质量。早期的紧凑型荧光灯启动很慢，产生了一种很“冷”的闪烁的光。今天的共识是，这样一个质量低劣的污名确实给整个行业带来了沉重的代价。只有这样的产品更多的新一代电子镇流器，使用改进的启动时间和减少闪烁在改善荧光粉产生温暖的光相结合，已经能够赢得一个心灰意冷的公共性。
LED technology has the potential to repeat the same mistakes. The pressure to reduce the cost of the solution is perhaps even higher， and it is for this reason that several governmental initiatives have been introduced to avoid falling in the same trap.［1］［2］［3］ It would be such a pity， because LED lighting promises to provide a much better lighting alternative under almost any possible point of view. LEDs do not require the presence of toxic materials such as Mercury， which is present in each fluorescent lamp. They have virtually no start time and can be made to produce a warm and pleasant light. In fact， LED lamps can easily provide any color temperature （Correlated Color Temperature［4］［5］） required， and are even adjustable on fly. LED lights can be dimmed easily， and can provide an extremely long service life （up to 50，000 hours） with an efficacy that is already superior to that of the best competing technologies. Yet， contrary to the other lighting technologies， they do always require the use of electronics.
