LED Mice
Optical mice often use LEDs for illumination, even though they are sometimes colloquially referred to as 'lasers'. The color of the optical mouse's light-emitting diodes can vary, but red is most common, as red diodes are inexpensive and silicon photodetectors are very sensitive to red light. Other colors are sometimes used, such as the blue LED of the V-Mouse VM-101 illustrated at right.

Famous quotes containing the words led and/or mice:
“Young women ... you are, in my opinion, disgracefully ignorant. You have never made a discovery of any sort of importance. You have never shaken an empire or led an army into battle. The plays by Shakespeare are not by you, and you have never introduced a barbarous race to the blessings of civilization. What is your excuse?”
—Virginia Woolf (1882–1941)
“A cat that catches mice does not meow.”
—Chinese proverb.
