In recent years, with its unique advantages, remote phosphor technology has been widely valued by lighting companies, and the development of remote phosphor lighting fixtures has sprung up. Currently, in the lighting terminal market, Philips “Queens Star†and Inter-American “ChromaLitTM†are typical representatives of remote-use phosphor products.
"The emergence of remote phosphors completely separates the phosphor substrate from the blue LED chip, which can effectively solve the problems of traditional solid-state lighting unidirectional illumination, uneven light color, difficult heat dissipation, limited design, etc. ChromaLitTM will become a design high efficiency Ideal for innovative lighting systems.†Recently, Dr. Liu Xiao, General Manager of Intel United China, mentioned in an exclusive interview with Gao Gong LED reporter.
Intermec's ChromaLit “remote phosphor†lighting source will change the traditional solid-state lighting design pattern, and its perfect lighting quality provides lighting designers with unprecedented freedom of creation, color control and the most flexible and efficient design system. At present, Inter-Tech is one of the best in the research and production of remote phosphors. Its ChromaLitTM2D series, ChromaLit TM3D series and ContourTM series of remote phosphor products are widely used in commercial, industrial and civil applications. Lighting field.
"High-tech LED reporter": At present, there are not many applications of remote phosphors. I believe most people are unfamiliar with the concept of remote phosphors. Would you please give us a brief introduction to the working characteristics of remote phosphors?
Liu Xiao: There are many companies researching remote phosphors in the world, but domestic LED companies still pay little attention.
The ChromaLitTM remote phosphor illumination source precisely attaches the phosphor composite to the substrate, completely separating the phosphor from the LED energy source, and the independently placed phosphor is excited by blue light to emit white light.
Since the phosphor is completely spatially separated from the blue excitation source, the luminaire is easier to make various shapes and display different color temperatures. At the same time, the light generation process is far away from the blue light energy source, which will greatly reduce the thermal interaction between the blue chip and the phosphor, and increase the amount of light output per unit input power of the blue chip and the phosphor, thereby further reducing the blue LED chip and the phosphor. The temperature makes the performance of the LED components more stable, maintaining the consistency of the design color and the uniformity of the lamps.
"High-tech LED reporter": Compared with the traditional phosphor coating method, what are the advantages of remote phosphors, or which problems exist in the traditional phosphor coating method, can you talk about it specifically?
Liu Xiao: First of all, a more free design space. The ChromaLitTM family of products uses precision optics and Intel's cutting-edge phosphor technology to enable lighting manufacturers to create products in specific shapes and colors.
The exterior, color temperature, indexing and substrate materials of the ChromaLitTM range are customizable, providing lighting manufacturers with unprecedented design flexibility and innovation opportunities. At the same time, it also solves the problem that traditional LED lighting technology needs to achieve uniform light distribution, curve distribution and three-dimensional lighting design.
Second, the more ambiguous light quality. Lighting products designed with ChromaLitTM technology, featuring glare-free and diffused light sources, produce continuous, high-quality light across multiple lighting fixtures; ChromaLitTM3D series delivers nearly 360-degree light intensity distribution for enhanced LED lighting The light output efficiency; the unique advanced phosphor process also enhances color rendering.
Again, a more streamlined process. By replacing ChromaLitTM materials, multiple color specifications can be easily obtained without replacing the entire fixture.
A standard blue LED energy source meets ChromaLitTM power requirements with different color temperatures and color rendering. Therefore, when the efficiency of blue LEDs in the market improves, the same ChromaLitTM product can be easily integrated into the new system, thereby reducing the inventory of lamps of various spectrums and reducing the risk of gross profit decline due to rapid price decline. .
Finally, higher system efficiency. Chroma LitTM products operate at lower temperatures, resulting in more light per input power. Compared to traditional white LED lighting systems, the ChromaLitTM system reduces the number of LEDs used, designs smaller heat sinks, drives higher LED currents, and reduces energy consumption. In addition, ChromaLitTM products eliminate the need for secondary optical scattering sources and achieve system performance of up to 30% over traditional LED lighting systems in white light illumination and specialty color lighting applications such as signal signage.
