LED Lighting - White

Light-emitting diodes (LEDs) are small semiconductor components that are extensively used in both industrial and consumer applications. They are becoming increasingly popular in white LED lighting applications across a wide range of industries. One such LED lighting product is the SPMWH1221FQ7GBTKSA LED, specifically designed for use in white LED lighting.

The SPMWH1221FQ7GBTKSA LED emits white light when electrically excited. It is made up of two separate dies – one die being a gallium nitride (GaN) p-n junction for blue light emission and the other being made of a silicone-carbide (SiC) based stack for phosphorescence. A combination of the blue and phosphorescence light emission make up the white light emitted from this device.

The SPMWH1221FQ7GBTKSA is a high power, high efficiency LED with a wide range of applications in architectural lighting, displays, signage, street lighting, automotive lighting, and interior lighting. It is easy to integrate, has a long lifetime, and is resistant to thermal shock and vibration. In comparison to other white LEDs, the SPMWH1221FQ7GBTKSA is more efficient and has a higher light output when operated at a given constant current.

The working principle of the SPMWH1221FQ7GBTKSA involves electric current passing through the two dies, exciting electron hole pairs and releasing photons. The release of photons from the GaN die is made possible by a process called ‘electroluminescence’, which occurs when electrons in the conduction band fill empty holes in the valence band, releasing energy that is converted into light. The release of photons from the SiC based stack is also internally brought about through the recombination of electrons and holes.

While the SPMWH1221FQ7GBTKSA LED is an excellent choice for applications in white LED lighting, it needs to be noted that it requires a special high power LED driver to operate. This LED requires a constant current of 350mA, with a forward voltage range between 13.9 and 16.1 Volts. In addition, the LED must be mounted within a printed circuit board with sufficient thermal management.

The SPMWH1221FQ7GBTKSA LED is highly versatile, easy to use, and has a long lifetime compared to other traditional lighting solutions. It is an ideal choice for a variety of white LED lighting applications and its high efficiency makes it a cost-effective choice for these applications.
