Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction.

Message LED displays are typically commercial or industrial signs.

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation

Digital bargraphs measure process and electrical variables such as pressure, flow, temperature, speed, current, and voltage.

Illuminators are used to provide adequate contrast for imaging.

LED lamps are light emitting diode arrays with traditional lamp ballasts

LED mounts and lenses are used to mount LEDs and shape or transfer light output.
