Light conversion technology innovation, accelerate the rise of intelligent lighting

LEDs are everywhere in life and are increasingly used in large-size, high-definition televisions, cars, streets, workplaces and homes. In recent years, LED prices have been continuously reduced, driving the global LED lighting market to flourish. However, we are facing the second wave of the LED lighting industry. Next-generation LED optical technology provides more comfortable, safe, high-quality and networked LED lighting at a more affordable price. Light Polymers, a San Francisco-based chemical materials startup, is revolutionizing the LED lighting industry with innovative and unique patented water-based liquid crystal materials.

Light Polymers specializes in the synthesis of aqueous liquid crystal materials for a variety of applications. Now, the company uses this unique chemical material in LED down-conversion to develop new Crystallin products, including recessed lights for architectural lighting, beauty lamps, LED lamps for red light therapy, plants, Fish and animal growth lights, professional photography lights and advanced personal lighting. Among them, the recessed light products were launched in the Asian market through sales partners and online channels in August this year, and were listed in the US in November.

"Light Polymers' advanced polymer technology is different from traditional fixed-color LED packaging technology," said Marc McConnaughey, CEO and CEO of Light Polymers, in an exclusive interview with LEDinside. "Light conversion technology is not a new concept for the LED industry, but limited by the degree of implementation and cost, this technology has not been widely used in lighting equipment."

In the past, high color rendering (CRI) lighting equipment was mainly used in places where museums and other performance requirements were very important. Light Polymers' water-based liquid crystal material technology allows lamps to emit comfortable and uniform light, not only with full color gamut (high CRI), but also with low glare and UV leakage. Because Light Polymers' chemical materials can reduce manufacturing costs, these ultra-high-quality lighting products will be able to compete in the market at a more reasonable price.

"Light Polymers' technology includes water-based liquid crystal materials with special properties that tightly encapsulate the phosphors to achieve maximum blue light conversion," explains Dr. Huang Zhihao of Light Polymers. “Therefore, a variety of low- and medium-power blue LEDs can be used, which not only eliminates expensive binning or picking operations, but also eliminates the need for expensive large heat sinks for high-brightness LEDs, adding extra cost. Developed using this technology. Lighting products minimize color shifts and reduce brightness degradation, and are more power efficient than LED lighting devices that use traditional packaging technology."

Light Polymer's Crystallin downlights create a new niche in the highly competitive LED downlight market. This is the thinnest recessed light on the market and offers museum-grade lighting for home or commercial lighting purposes at a price that is close to the people.

Zhang Jiarong, vice president of Light Polymers, said: "We can design any spectrum in a few days. We will introduce a customized service to provide different spectral phosphor films according to customer needs. The recessed lamp is a mass market that is sensitive to cost, but We believe that there is a demand for high-cost CRI recessed lights at reasonable prices.” Light Polymers' 6-inch recessed lamp Crystallin Gold has high color rendering (CRI greater than 98), color temperature 3000K and 5000K, and the recommended price (MSRP) is $14.99. In addition, 6-inch downlight products include Crystallin Red (using spectrum that does not affect sleep), Crystallin Orange (for environments that are sensitive to light, such as semiconductor factories and programmers who like to encode in orange light), for beauty Crystallin Salon designed by Nail Salon, and Crystallin Grow (houseplant growth lamp).

Light Polymers also offers Crystallin Custom services to allow customers to customize the spectrum. Light Polymers has also invested in multi-layer film development, making luminous efficiency more than 30% higher than traditional lamps.

"At present, the efficiency of LED design has stabilized. To further improve overall efficiency, the key is to develop more efficient optical components," McConneughey said.

For LED lighting manufacturers, plant lighting is a fairly profitable market. LEDinside estimates that the global LED plant lighting market will grow from $576 million in 2016 to $1.42 billion in 2020.

"Light Polymers' chemical technology helps develop low-cost LED light conversion technology and offers new ways to make plant lights," said Marc McConnaughey. “The existing LED process is still unable to design and provide special spectra according to customer requirements, and the production lead time is quite short. Our plant growth lamps are designed for vertical farms to achieve maximum luminous efficiency and photon flux density (PPFD). At the same time, we reduce the electricity consumption of lighting and air conditioning. Through light conversion technology and simple, low-cost blue LED, we can provide accurate growth spectrum according to customer needs."

Light Polymers will also introduce GrowBlade light-conversion flat-panel lamps in the near future, including 300x300mm, 300x600mm, 300x1200mm and 300x1500mm. With high luminous efficiency, GrowBlades is designed for indoor farms that require a fixed spectrum while balancing low capital and operating costs. GrowBlades uses a uniform-glowing Crystallin film with a 3 cm ultra-thin design that provides greater planting space and increased vertical farm productivity. Through large-area illumination and special Crystallin Grow film spectroscopy, not only can improve the quality of light, but also increase crop yield. According to the initial field test, a GrowBlade can replace 2 to 3 tubes of multi-color packaged LEDs.

As medical and recreational marijuana is legalized in many countries, it is expected to further boost the demand for global LED plant lighting. Light Polymers hopes to help plants achieve optimal growth through innovative plant lights and unique top and side lighting designs to capture the business opportunities in this niche market.

In addition to LED downlights and plant lighting, Light Polymers will also launch beauty-specific red light therapy products this fall. Light Polymers' advanced light conversion films use low-cost blue LEDs to provide red light for phototherapy at a much lower cost than previous generation technologies. Light Polymers has recently demonstrated a 660nm phototherapy red light film.

“Aqueous liquid crystal materials can be used in many high-performance professional applications at reasonable prices,” said Ye Meijun, Asia Business Development Manager, Light Polymers. “There are already high-end hotels in contact with us, hoping to install related equipment to provide red light treatment for tenants.”

Red light therapy has been approved by the US Food and Drug Administration (FDA) for use in the United States. The NASA study found that red light can relax muscles, regenerate gums to reduce wrinkles, and repair sunburned skin. Light Polymers' red light products are available in 300x600mm and 300x1200mm sizes and are designed in a modern consumer electronics industry.
