The LED umbrella is inspired by the neon umbrellas of Blade Runner. They lighted the dark streets of dystopian Los Angeles in 2019 and now they can illuminate our world too, with the Rain-Glo LED umbrella now available online at ThinkGeek.com.
LED stands for 'light-emitting diode.' When electrons in the diode are brought from a state of high energy to a state of low energy, the energy difference is emitted in the form of light known as electroluminescence. LED technology has been around since the early 20th century, but did not go into commercial use until the 1960s due to high cost of production. The technology saw an advancement a decade later in the increased light-emitting power of the diode, and therefore affected the overall vision of the possiblites of LED lighting.
We now use LED technology for the most basic of applications, from indicator lights to large video screens and handheld devices. However, incorporating an LED light into an umbrella makes this ordinary object seem otherwordly.
