资料介绍:

发光二极管产生更多的光线每瓦特,比白炽灯泡;这是非常有用的,在电池供电或节能设备。
发光二极管能发光的一打算颜色不需使用彩色滤光片,传统的照明方法要求。这是更有效率和更可以降低初始成本。
坚实的整套的LED能够在设计上把重点放在它的光。白炽灯和日光灯的来源,往往需要一个外部反射器,以收集轻和直接的,它在实用的方式。
使用时,在申请的地方是需要调光,发光二极管不改变其颜色色彩作为当前通过他们的降低,不像白炽灯,变黄。
发光二极管是理想的使用在应用程序都受到频繁,对小康骑自行车,不像荧光灯认为,烧伤了更迅速地时,经常骑自行车,或躲在灯需要一段长时间才重新启动。
发光二极管,固态元件,是很难的损害与外部冲击。荧光灯和白炽灯泡很容易破碎,如果下降,在地面上。

LED schematic symbol
LEDs produce more light per watt than incandescent bulbs; this is useful in battery powered or energy-saving devices.
LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs.
The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.
When used in applications where dimming is required, LEDs do not change their color tint as the current passing through them is lowered, unlike incandescent lamps, which turn yellow.
