LED Chips/Modules: Power Rating 0.5-5W per chip

Component Specifications

Definition

LED chips/modules are solid-state lighting components consisting of semiconductor materials (typically gallium nitride-based compounds) mounted on substrates with electrical connections. They emit light through electroluminescence when current passes through the p-n junction. In LED panel lights, these components are arranged in arrays or modules to provide uniform, energy-efficient illumination with precise color temperature and brightness control.

Working Principle

Electroluminescence: When forward voltage is applied across the p-n junction of semiconductor materials, electrons recombine with electron holes, releasing energy in the form of photons. The wavelength (color) of emitted light depends on the energy band gap of the semiconductor materials used.

Materials

Semiconductor: Gallium nitride (GaN), indium gallium nitride (InGaN), aluminum gallium indium phosphide (AlGaInP); Substrate: Sapphire, silicon carbide, or silicon; Encapsulation: Epoxy resin or silicone; Electrodes: Gold, copper, or aluminum; Phosphor coating (for white LEDs): Yttrium aluminum garnet (YAG) doped with cerium.

Frequently Asked Questions

What is the difference between LED chips and LED modules?

LED chips are individual semiconductor dies that emit light, while LED modules integrate multiple chips with drivers, optics, and thermal management into a single packaged unit ready for installation in lighting fixtures.

How do LED chips produce different colors?

Different semiconductor materials create different colors: InGaN produces blue/green, AlGaInP produces red/orange. White light is typically created by combining blue LED chips with yellow phosphor coating or mixing multiple colored chips.
