PAY TYPE DESCRIPTIONS - ALPHABETICAL ORDER. The following table contains the current list of DOS codes or Pay Types at UCLA in order by DOS code. This list can be sorted by DOS Code, Pay Type/Check Description, or Full Description. To sort by one of the columns listed, click on the column heading.
a light emitting diode led is a semiconductor device that emits visible light when an electric current passes through it the light is not particularly bright but in most leds it is monochromatic occurring at a single wavelength
The light-emitting semiconductor material determines the LED's color, so the number of colors is infinite. As indicated by its full name â Light Emitting Diode â an LED is a diode that emits light. A diode is a device that allows current to flow in only one direction. Almost any two conductive materials will form a diode when placed in contact with each other â with a single p-n semiconductor junction between them.
