LED FAQS:




How are white LEDs created?

There are currently two ways to make white light with LEDs. One method mixes multiple wavelengths of different LEDs to make white light (i.e. RGB); allowing the lighting designer to tune the white light to a specific color temperature.

The second method uses a blue Indium-Gallium-Nitride (InGaN) LED with a phosphor coating to create white light. This is the method that results in the more commonly seen "white LED".




High Color Rendering Index (CRI)

Color Rendering Index or CRI is the calculated rendered color of an object. The higher the CRI (based upon a 0-100 scale), the more natural the colors appear.




What is LED?

A lighting-emitting diode (LED) is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction of p-n junction. The color of the emitted light depends on the composition and condition of the semiconducting material used, and can be infrared, visible, or near-ultraviolet.




What is forward voltage (Vf)?

Forward voltage (Vf) is the voltage across a diode for a given forward current.




What is phosphor?

Phosphor is an inorganic chemical compound processed into a powder and deposited inside the dome of an LED packaging. Phosphors are designed to convert the wavelength of light. Foryard Optoelectronics LEDs use proprietary phosphors from the global leading company.
