10MM LED RBG LED Module Light Emitting Diode

10MM LED RBG LED Module light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The colour of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the bandgap of the semiconductor

Initial commercial development:

The first commercial visible-wavelength LEDs were commonly used as replacements for incandescent and neon indicator lamps
and in seven-segment displays. First inexpensive equipment such as laboratory and electronics test equipment,
then later in such appliances as calculators, TVs, radios, telephones, as well as watches (see list of signal uses).
Until 1968, visible and infrared LEDs were extremely costly, in the order of US$200 per unit, and so had little practical use.

LED uses fall into four major categories:

Visual signals where the light goes more or less directly from the source to the human eye, to convey a message or meaning
Illumination where light is reflected from objects to give visual response of these objects
Measuring and interacting with processes involving no human vision
Narrowband light sensors where LEDs operate in a reverse-bias mode and respond to incident light, instead of emitting light

Development  Resources: demo codes, schematics, datasheets, etc

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
