An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
Several LED spots being reflected as continuous lighting strip. An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing.
A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light-emitting diodes (LEDs).
Reported in the January 5, 2004 issue of the journal Applied Physics Letters, Milton Feng and Nick Holonyak, [1] the inventor of the first practical light-emitting diode (LED) and the first semiconductor laser to operate in the visible spectrum, made the world's first light-emitting transistor.
The GaAs 0.60 P 0.40 laser diode worked at low temperatures, but the device still functioned as a light-emitting diode at room temperature. [8] The demonstration of red light emission from the diode inspired the article "Light of Hope – or Terror" in Reader's Digest. GaAsP was the material used for the first generation of commercial LEDs that ...
Detail view of an LED display with a matrix of red, green and blue diodes The 1,500-foot (460 m) long LED display on the Fremont Street Experience in Downtown Las Vegas, Nevada, is currently the largest in the world. A LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) as pixels for a video display.
