LED
Lighting
照亮未來世界的一盞明燈
LEDs
have come a long way since they were invented in 1962. In the beginning, only
red lights were available, but now they come in a whole range of colors. Also,
they were first used to light up digital clocks, watches, and calculators. Now,
they are commonly used in flashlights, traffic lights, and electronic bulletin
boards. What's more, LEDs have made the images you see on TV more vivid in
color as well as made it possible for thinner TVs to be created.
Unfortunately, the biggest downside to LEDs is the cost. They are currently more expensive than traditional lights, but this is changing. Even though LEDs cost more at first, the long-term benefits to customers' wallets and to the environment are worthwhile. LEDs are sure to light up the world far into the future.

LED從1962年發明以來已有了長足的進步。它們剛開始的時候只有紅燈，但現在卻做成各種不同的顏色。另外，它們最初只用來照亮數字時鐘、手錶和計算機。現在則是常用於手電筒、交通信號燈和電子佈告欄上。更重要的是，LED能使您在電視上看到的影像色彩更加鮮豔，同時也讓更薄的電視能夠製造得出來。
不幸的是，LED的最大缺點就是成本。它們目前比傳統電燈要貴，但這種情況正在改善當中。即便LED一開始的成本比較高，但就消費者荷包和環境兩者的長期效益而言卻是十分值得的。LED肯定會持續為世界照亮邁向未來的路。
