A light conversion film enables LED lamp designers and manufacturers to produce any light color or spectrum in any format from a single type of LEDs without complex electronics and drivers. This can be achieved using color conversion phosphor materials capable of covering virtually the entire visible (even some of the invisible) electromagnetic spectrum.
Today, many commercial LEDs use phosphors to convert some of the violet/blue light to green/yellow/red light for a wide variety of indoor/outdoor applications. Such LEDs are generally referred to as phosphor-converted LEDs or pcLEDs. This includes not only general illumination for residential and commercial buildings but also other forms of lighting such as automotive, aerospace, street lighting, horticulture, greenhouse lighting, even backlighting for displays used in portable electronics.
PhosphorTech’s enhanced light conversion films use a unique roll-based coating process to achieve superior performance while simultaneously reducing phosphor material usage between 33-50%, depending on the desired color temperature. The higher performance is a result of increased blue LED light absorption combined with reduced optical scattering losses due to thinner phosphor layers being used within the color converting film technology.
The color conversion phosphor films are compatible with a wide range of forming and printing technologies. This includes vacuum forming (thermoforming) and even 3D printing. This enables the production of hybrid light-emitting 3-dimensional optical structures never before possible. Using this approach, PhosphorTech developed a hybrid phosphor/nanocrystal structure with significantly improved performance for medium to high power lighting applications.
