The lens extracts and directs the light emitted from the die. The phosphor can be applied to the die directly, or it can be mixed into the lens material, which typically consists of silicon or glass. When the blue light hits phosphor particles, they glow and emit white light. In order to achieve the target color, phosphor is used. This allows easier integration of the LED into a fixture and provides an efficient way to bring power to the LED.įor general lighting applications, white light is generally desired, not blue. One or more die are then mounted to a substrate commonly made of aluminum or ceramic. When electric current passes through the die, it emits blue light. The LED die is a semiconductor device made of gallium nitride (GaN). LEDs consists of four main parts: die, substrate, phosphor and lens. LED lighting can also be referred to as solid-state lighting (SSL) because an LED is solid-state technology similar to the memory in your computer. An LED is a component of the entire fixture. LED stands for Light Emitting Diode, and this light source should not be confused with a light fixture or luminaire. As the technology continues to revolutionize the lighting industry, it’s important to understand how an LED light source works. LED lighting offers many advantages over traditional light sources, opening new ways to use light that weren’t possible before. Our LEDs are optimized for consistent performance in varying and demanding conditions, as well as energy efficiency, long life and low maintenance. Our LEDs create a welcoming ambiance, stimulate consumer behavior, and integrate smoothly with building management systems.
