Here are my personal understandings:
Remote phosphor technology is another way you can take to create LED lighting applications. The remote phosphor light source component technology is achieved by coating the phosphor on the substrate rather than integrating it into the LED wafer package. Combine the remote phosphor board with the sapphire blue and the blending chamber to achieve white light without visible point light. This method can provide low glare systems, or higher system efficiency, improve reliability and reduce color shift with time.
Working principles for remote phosphors:
Intermatix's ChromaLit accurately attaches a composite phosphor to the substrate and separates it from the blue LED light source. The independent phosphor glows under the excitation of blue light. Since the phosphor has been separated from the light source and can be made into arbitrary shapes and colors, unidirectional light, hot spots, inconsistencies and design constraints are no longer a challenge for solid state lighting.

Phosphor away from the LED chip, the phosphor away from the LED chip bulb, the phosphor away from the LED chip downlight, away from the phosphor high power LED lights, 30000lm, more than 10000lm, LED lights, LED studio lights, low temperature phosphor LED lamps.
1st, variable any shape and color
CHROMALIT series of products used in the fluorescent plate on the phosphor fine coating, the phosphor and blue chip separated, the phosphor on the fluorescent plate by blue light excitation and light. Because this technology will be separated from the blue chip and phosphor a distance, so the fluorescent plate can be made into any shape and color, the previous solid-state lighting there is a one-way light, resulting in hot spots, light inconsistency and design constraints are no longer Is a challenge in this field.
At present, the United States has introduced a round, square, rectangular and line type flat fluorescent plate, also introduced a candlelight, ellipsoid and hemispherical curved phosphor film, especially in May 2012 launched a circular fluorescence Powder, can replace the traditional 75W or 100W incandescent, fully meet the energy star size, light distribution curve and light efficiency requirements.
2nd, the unprecedented freedom of design
The CHROMALIT range of products combines precision optical manufacturing and phosphor precision coverage technology to provide lighting manufacturers with variable lighting and lighting for any shape and color. CHROMALIT series of products for any geometric shape, color temperature, refers to the material and the substrate. And for the light field to open up unprecedented flexibility and creativity. Making the curve lighting and stereo lighting has become a reality. Flat type Chromalit fluorescent panels are 22.5mm, 34mm, 45mm, 61.5mm, 75mm, 100mm, 135mm, 215mm, 200mm, 305mm (0.9in, 1.3in, 1.8in, 2.4in, 3.0in, 3.9in, 5.3in , 8.5in, 7.9 inches, 12 inches), luminous flux can cover any luminous flux in the range of 110lm to 30000, color temperature can choose 2700K, 3000K, 4000K and 5000K, color rendering index of 70 CRI, 80 CRI and 90CRI choice, made Lamps up to CRI96 or more, the best color deviation can be controlled within a color tolerance, 1 SDCM color consistency.
3rd, the unique style of promotion refers to CHROMALIT unique design to improve the show, and another INTEMATIX company's patented phosphor technology to ensure the stability of the phosphor in the light of the color consistency and uniformity and longevity have a more excellent performance.
4th, Remote phosphor has solved the process problem
The traditional color temperature and color rendering index LED package to prepare a different LED chip and phosphor formulations, and encapsulated white LED has a large color or color temperature deviation, yield is not high.
The replaceability of the CHROMALIT series simplifies the problem of BIN and reduces the required inventory for a larger spectral range. CHROMALIT series of products do not have to replace the entire light can be easily converted into a variety of colors, only one LED can be used with different CHROMALIT series of products evolved a variety of color temperature, refers to, R9. As the blue LED energy efficiency continues to increase, so a CHROMALIT fluorescent plate can be easily integrated into a new lighting system.
5th, To improve energy efficiency by 30%
Unprecedented life and energy efficiency, the use of CHROMALIT series of products compared to traditional LED lighting system increased by 30% of the luminous efficiency, so that the lower temperature, the greatest use of the photon, reducing the light diffusion. Using the CHROMALIT fluorescent plate to emit more light at the same power input, increasing the service life of the LED package, reducing the junction temperature of the LED chip, the CHROMALIT fluorescent board is designed with less LED, smaller heat sink, higher The drive current and the lower energy consumption to send more light.
6th, The future prospects for remote phosphors
In order to better guide the future development trend of LED lamps, the United States and the United States in the United States laboratory research and development of new materials to improve the old process, the future will be reflected in the superiority:
1. Improved optical control
2. More color temperature and refers to the choice
3. For more environments
4. Tailor-made shape and size
Those are just my understandings. What is your idea ? Do you agree with my ideas ? Any of your ideas would be highly appreciated.
Ps: Excuse me if I was wrong in words or expressions as I am a green hand in the field of remote phosphors. I need continual learnings.
May someone would like to help ?
thanks in advance.
