LED Phosphor Application

The most common, and cost-effective, method of delivering white light from an LED is to combine a blue “pump” LED source under a layer of phosphor or phosphor blends to achieve the desired spectrum. While there are relatively few manufacturers of high-quality blue LED die, there are a substantial number of companies that purchase those raw blue die and package them into finished white LEDs, ready for sale and eventual integration into a luminaire or replacement lamp, signage, or backlight, such as we see in our smartphones, laptops, and flat panel TVs.
