高三英语练习:Module 11三四单元同步评估阅读理解四
D
How about a carpet that can guide you to your bedroom during nighttime without ever turning on the lights or protect your toes during a fast trip to the bathroom? Well, you could buy the next best thing, an electroluminescent rug (场致发光地毯) which lights up while you walk on it. This would surely be one of the future floor fashion devices found in everyone’s home. However, you will have to wait a bit before it will be marketed.
The new rug called Footlume was developed by Leona Dean and Zoe Robson, two engineering students from the London South Bank University. It makes use of rechargeable batteries which power the lights of the rug. The rug produces light through electroluminescence which uses electric fields to emit (发出) visible light.
Other means to produce light involve photoluminescence (光致发光) which uses substances that absorb light to experience an excited state after which light is re-emitted into the medium, and chemoluminescence (化学发光) which produces light during chemical reactions between light- -producing substances.
“It could be helpful as a child’s night light, to help the elderly to find their way in the dark, or even to light the way to bed after a night in the bar without waking up your partner. It is pressure-operated and runs on very little power from rechargeable batteries, and it can be used anywhere in the home,” said co-inventor Leona Dean.
When asked how the two inventors got the idea for the product, they said, “We often use our mobile phones to light our way in the dark. By using the same light source, electroluminescent panel (显示板) and transferring it into a pressure activated rug, we have created an energy efficient alternative to turning on a light switch.”
The new rug is expected to be exhibited this month at the Daily Mail Ideal Home Show in London.
