The important aspects of the optical parameters of LED are: luminous flux, luminous efficiency, luminous intensity, luminous intensity distribution, and wavelength.
LED lamps are light-emitting diodes, which use solid semiconductor chips as luminescent materials. Compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, and have good color rendering and response speed.
Like ordinary diodes, light-emitting diodes consist of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, the holes injected from the P region to the N region and the electrons injected from the N region to the P region are respectively connected with the electrons in the N region and the empty holes in the P region within a few microns near the PN junction.
Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and the like.
Light-emitting diodes, abbreviated as LEDs, are commonly used light-emitting devices that emit energy through the recombination of electrons and holes, and are widely used in the field of lighting.
