照明用LED技术的演进与发展

Development and Evolution of LED Illumination Technology

LED发光效率高、使用寿命长、不易破损、耗电量少甚至与传统灯具相比更适合用于低温环境。鉴于这么多的优点,LED用于下一代照明灯具的呼声最高。但是世界上的物品很少有所谓的绝对完美,LED初期成本较高,没有妥善处理散热问题而容易减短使用寿命,光源属于方向性,灯具设计需要考量光学特性。直到现今,国际上仍未有通用规范与标准。

LED has the luminous efficiency to be high, the service life long, is not easy to damage, the power consumption little even to compare with the traditional lamps and lanterns suitably to use in the low temperature environment, has these many merits, under becomes generation＇s illumination lamps and lanterns＇ call to be highest. But in the world goods very little have so-called absolutely perfect, the LED initial period cost is high, has not dealt with the radiation issue easily to lessen properly the service life, the photo source to belong to the directivity, the lamps and lanterns design must consider the optical character, until the nowadays, internationally still had not had the common standard and the standard…
