● CREE is one of the earliest companies to make the RPT research and development, they applied for many technology patents for RPT before the year of 2010.
● INTEMATIX made great efforts to promote the RPT and applied for many technical patents based on the technology of CREE. Intematix released very successful CHROMALIT XT technical solution in 2012. CHROMALIT XT solution published the light emitting devices in different shapes.
● Authorized by Cree and Intematix, Philips made great efforts on the application of RPT, they released the RPT LED lamp which got "L" prize from DOE of USA. This lamp brought the RPT to a new era of practical application.
RPT Advantages described by Philips:
● System works in Lower temperature & Higher efficiency.
● System works more reliable and steady, longer life time.
● Lower down the working temperature of the phosphor, slow down the degenerate rate of the phosphor layer, longer life of the phosphor, increase the light output efficiency of the phosphor.
● Excellent color stability, stable flux output and consistency of the color temperature.
● Lower lumen decrease rate than non-RPT LED products.
● Less glaring than non-RPT LED products.
Advantages of Remote Activate Technology (RAT) lamps:
● Besides the above 6 points advantages
● Our Remote Activate Technology (RAT) use normal phosphor, low cost on materials.
● Low cost phosphor, patented manufacturing process for the light emitting devices and the special Blue led chips. These features ensure our RAT products could be commercialized in large batches with acceptable market price and excellent performance of system low temperature and color consistency.

FAQ: 1. Why are LED's considered an environmentally friendly technology?
LED's are considered to be environmentally friendly in a number of ways:
Firstly, they are designed to have a long life span which can offer around 20 years of near maintenance-free service. Unlike conventional street lighting units, there is no lamp to change which means no waste. Assuming a conventional street light is re-lamped every four years, that's five re-lamping cycles over a 20 year period. As such, there is
• reduced disposal of old lamps containing harmful mercury;
• reduced fuel used and the accompanying pollution to service those fixtures;
• reduced potential for congestion on the highway network through lane closures or road works;
• less natural resources and energy used to produce the replacement lamps;
• less fuel used to transport the lamps from the factory (most likely overseas), to the distributor, to the contractor, to the job site. Additionally, LED's use significantly less energy and their light output can be controlled more efficiently than traditional street lights, which in turn reduces the amount of Carbon emissions from production of the electricity required to operate the lights. As LED's emit light in a specific direction, which is aimed at providing uniform illumination of the area to be lit, it will reduce light trespass and light pollution. The products that have been selected for this project are RoHS compliant, contain no lead or mercury and feature an aluminum enclosure so that the unit is 100% recyclable.
2. What is a MacAdam Ellipse?
This is an elliptical region on the CIE chromaticity diagram that contains all the colors that are indistinguishable to the average human eye, from the color at the center of the ellipse. Adjacent ellipses are "just distinguishable" in terms of color. This system is used to refine the binning process of LED colors. Slight color differences in the appearance of LED light are measured in MacAdam ellipses or steps.
3. What is the SPD of a light source?
SPD is the Spectral Power Distribution of a light source. The visible white light that we see is made up of a spectrum of various colors of light, ranging from wavelengths of 380nm (violet) to 760nm (red). The SPD is a graph that shows the power (strength) of each wavelength of light produced by a particular light source.
