LEDs, or light emitting diodes, act as a semiconductor which produces light once voltage is applied. LED light engines and modules use the same LED technology as traditional LED light bulbs, but they offer a unique twist on the classic design.
LED light engines and modules function as traditional light bulb substitutes. However, unlike the traditional light bulb design, LED light engines and modules consist of diodes arranged on a board.
While both LED light engines and modules consist of diodes on a circuit board, a few differences exist between them.
LED modules, also called LED arrays, are simple LED assemblies. They use one or more diodes arranged on a circuit board. The circuit boards that LEDs use involve printed circuit boards (PCB) made of materials designed to improve heat dissipation.
Because they do not contain operational and control components like a driver or protective circuits, LED modules require those active components to operate.
LED light engines often include LED modules. LED light engines function as an integrated assembly of one or more LED diodes, modules, or arrays. They contain optical, mechanical, electrical, and thermal components, including an appropriate heat sink to protect the light engine from overheating. Because LED light engines come equipped with these additional components, they typically only need input voltage to operate.
LED light engines often come equipped with an integrated driver. If no driver is included, they require an external driver to power them. MaxLite offers some LED linear light engines, like this one, with linkable connections.
LED light modules can be used in outdoor lighting, undercabinet lighting, accent lighting, and other decorative lighting applications. LED modules and arrays can also come in integrated LED fixtures.
LED light engines can come as a component in an integrated fixture or retrofit old fixtures. They can see use in round or linear light sources depending on the shape of the light engine.
LED light modules consist of one or more light emitting diode. See how LED modules work and what their uses can be!
LED drivers provide the light bulb with the electricity needed to function. If your LED bulb stops working unexpectedly, you might need to replace your external driver.
The LED chip makes up the most important component of an LED light bulb. LED chips determine the voltage, brightness, and wavelength.
