Fundamental concepts of LED lamps and light sources

One, with the LED light source definitions related
          Whether LED array, LED module or LED lights are light.
(1) light (lamp): to generate optical radiation (usually visible) light source manufactured.
Note: this term is also sometimes used for certain types of lighting devices.
(2) light-emitting diode (Light Emitting Diode (LED)): The non-coherent optical radiation emitted pn junction forward bias voltage of the semiconductor device. Spectra may be emitted ultraviolet, visible or infrared wavelength region.
(3) LED chip (LED die): a piece of semiconductor material on a given assembly line of LED light emission function.
(4) LED array or module (LED array or module): a printed circuit board or substrate in the LED package (elements) or wafer assembly, the optical element may have additional thermal, mechanical, and intends to link to the LED driver load electrical side of the interface. The installation without power and norms caps. The installation does not directly interface with the branch circuit. As shown in Figure 1.
         (5) LED package (LED package): includes one or more pieces of wire interface LED chip components or other types of electrical interface elements, possibly with optical elements, thermal, mechanical and electrical interfaces. The installation does not include the power and norms caps. The installation does not directly interface with the branch circuit. As shown in Figure 2.
         (6) LED driver (LED driver): containing the power supply and the LED control circuit is installed, the purpose of the LED package (element), or an LED array (modules) or LED lamp operation.
(7) Non-Integrated LED lights (LED lamp, non-integrated): contains LED array (module) or LED packages (components) and regulate lamp components. After the installation intends to regulate the lamp holder adapter LED driver. The installation does not directly interface with the branch circuit.
(8) integral LED lamp (LED lamp, integrated): contains the LED package (component) or LED arrays (modules), LED drivers, and other specifications lamp photometric, thermal, mechanical and electrical components of the overall portfolio. After the installation of standardized holder intends to directly interface with the branch circuit. As shown in Figure 4.
(9) LED light engine (LED light Engine): contains the LED package (component) or LED arrays (modules), LED drivers, and other photometric, thermal, mechanical and electrical components of the total portfolio’s. The installation of LED lamps to go through a routine convergence matched directly link to the branch circuit, the LED lamps designed to not use standardized holder
