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:
“In our great concern about the mental health of children, however, we have overlooked the mental health of mothers. They have been led to believe that their children’s needs must not be frustrated, and therefore all of their own normal angers, the normal ambivalences of living, are not permissible. The mother who has “bad” feelings toward her child is a bad mother.”
—Elaine Heffner (20th century)
“will your eyes lie in wait,
little field mice nestling on their paws?
Perhaps they will say nothing,
perhaps they will be dark and leaden,
having played their own game
somewhere else....”
—Anne Sexton (1928–1974)
