| Array |
|
an order of arrangement of LED |
|
|
|
| Chip |
|
usually made up of silicon, a chip is a minute semiconductor which contains hundreds and thousands of electronic components. It is also known as an integrated circuit |
|
|
|
| Chip-on-board (COB) |
|
a semiconductor assembly technology wherein the microchip or die is directly mounted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or packaging |
|
|
|
| Die |
|
a semiconductor that has not yet been packaged. Also known as a group of “chips” |
|
|
|
| HB LEDs |
|
high brightness LEDs |
|
|
|
| Incandescent lighting |
|
light produced when a filament is heated to incandescence using an electric current (e.g., light bulb). Incandescent lighting is very inefficient – turning much of its energy into heat rather than light – and is gradually being replaced in many applications by LEDs and other devices |
|
|
|
| Laser |
|
an acronym derived from Light Amplification by Stimulated Emission of Radiation, denoting a device which emits coherent light of a specific wavelength |
|
|
|
| LED |
|
also known as a light-emitting diode; an LED is a solid-state semiconductor that emits light. LEDs are used in a variety of display and lighting applications, and consume less power than incandescent bulbs |
|
|
|
| Light engine |
|
a sub-system used to generate light, which typically includes a lamp module, optics and projection lens |
|
|
|
| Light source |
|
any device serving as a source of illumination |
|
|
|
| Packaged LED |
|
an LED package has an optical lens, bonding wire (to bond the package to the printed circuit board), electrodes, and resin to encapsulate the LED for projection |
|
|
|
| Photon |
|
a quantum of electromagnetic energy commonly known as a particle of light |
|
|
|
| RGB |
|
acronym for red, green and blue, which are the three primary colors of light. Also refers to the color model for displays and monitors, where combinations of illuminated red, green and blue pixels are used to create a wide variety of colors |
|
|
|
| Semiconductor |
|
a material whose electrical resistance can be switched between insulating and conducting. Silicon is the most commonly used semiconductor material and the basic material for building most electronics chips |
