LEDs are everywhere in our daily lives and are increasingly being integrated into large-screen TVs, automobiles, public spaces, work environments, and residential settings. Over the last few years, the cost of LEDs has dropped significantly, fueling a boom in the global LED lighting market. However, we're now witnessing the dawn of the next phase in LED lighting technology. The next generation of LED optics promises to deliver more comfortable, safer, higher quality, and networked lighting solutions at even more accessible price points.
Based in San Francisco, Light Polymers, a pioneering chemical materials startup, is shaking up the LED industry with its cutting-edge and proprietary water-based liquid crystal materials. These materials offer innovative solutions that enhance LED performance across various applications.
Light Polymers specializes in synthesizing aqueous liquid crystal materials tailored for numerous uses. Currently, the company is leveraging this unique chemical material in LED down-conversion to develop novel Crystallin products. These include architectural recessed lights, beauty lamps, LED lamps for red light therapy, plant growth lights, fish and animal illumination systems, professional photography lights, and advanced personal lighting solutions. Among these, the recessed light products made their debut in the Asian market via sales partners and online platforms in August this year, with plans to roll out in the U.S. in November.
"Light Polymers' advanced polymer technology stands apart from traditional fixed-color LED packaging methods," remarked Marc McConnaughey, CEO of Light Polymers, during an exclusive interview with LEDinside. "While light conversion technology isn't entirely new to the LED industry, its widespread adoption has been hindered by implementation challenges and costs."
In the past, high color rendering (CRI) lighting was primarily utilized in settings requiring exceptional performance, such as museums. Light Polymers' water-based liquid crystal material technology enables lamps to emit soft, uniform light, offering a full color gamut (high CRI) while minimizing glare and UV leakage. Since Light Polymers' chemical materials reduce manufacturing expenses, these superior lighting products can compete effectively in the market at more competitive price points.
"Light Polymers' technology incorporates water-based liquid crystal materials with unique properties that encapsulate phosphors efficiently, maximizing blue light conversion," explained Dr. Huang Zhihao of Light Polymers. "This allows the use of lower and mid-power blue LEDs, eliminating costly binning or sorting processes and reducing the need for expensive, bulky heat sinks for high-brightness LEDs. Products developed using this technology exhibit minimal color shifts and brightness degradation while being more energy-efficient than those utilizing conventional packaging techniques."
**Mastering the Market Niche with High-CRI LED Downlights at Affordable Prices**
Light Polymers' Crystallin downlights carve out a distinct niche within the fiercely competitive LED downlight market. These are some of the thinnest recessed lights available, offering museum-grade lighting for both residential and commercial applications at prices accessible to the general public.
Zhang Jiarong, Vice President of Light Polymers, stated: "We can design any spectrum within a few days. We'll introduce a custom service to provide tailored spectral phosphor films based on client needs. While the recessed light market is cost-sensitive, we believe there's significant demand for high-CRI recessed lights priced reasonably." The Crystallin Gold 6-inch recessed light boasts a high color rendering index (CRI > 98), with color temperatures of 3000K and 5000K, and a suggested retail price (MSRP) of $14.99. Other 6-inch downlight models include Crystallin Red (designed to avoid sleep disruption), Crystallin Orange (ideal for light-sensitive environments like semiconductor factories and coders), Crystallin Salon (tailored for nail salons), and Crystallin Grow (a houseplant growth lamp).
Light Polymers also offers Crystallin Custom services for clients looking to personalize their lighting spectrums. Additionally, the company has invested in multi-layer film development, boosting luminous efficiency by over 30% compared to traditional lamps.
"At present, LED design efficiency has plateaued. To further enhance overall efficiency, the focus should be on developing more effective optical components," noted McConnaughey.
**Thriving in the LED Plant Lighting Sector**
For LED lighting manufacturers, plant lighting represents a lucrative market segment. LEDinside projects that the global LED plant lighting market will expand from $576 million in 2016 to $1.42 billion by 2020.
"Light Polymers' chemical technology facilitates the development of low-cost LED light conversion solutions, providing innovative approaches for creating plant lights," said Marc McConnaughey. "Existing LED processes struggle to design and supply customized spectra according to specific customer requirements, with long lead times. Our plant growth lamps are optimized for vertical farms, achieving maximum luminous efficacy and photon flux density (PPFD). By using light conversion technology and simple, cost-effective blue LEDs, we can provide precise growth spectra tailored to customer needs."
In the near future, Light Polymers will introduce GrowBlade light-conversion flat-panel lamps, available in sizes 300x300mm, 300x600mm, 300x1200mm, and 300x1500mm. Designed for indoor farms requiring a fixed spectrum while balancing low capital and operational costs, GrowBlades feature a uniform-glowing Crystallin film with a 3 cm ultra-thin design, providing greater planting space and enhanced vertical farm productivity. Through extensive area illumination and specialized Crystallin Grow film spectroscopy, GrowBlades improve light quality and crop yields. Initial field tests indicate that a single GrowBlade can replace two to three tubes of multi-color packaged LEDs.
As medical and recreational marijuana legalization spreads across many countries, global demand for LED plant lighting is expected to surge further. Light Polymers aims to capitalize on this niche market by helping plants achieve optimal growth through innovative plant lights and unique top and side lighting designs.
**Exploring Beauty Red LED Phototherapy**
Beyond LED downlights and plant lighting, Light Polymers plans to launch beauty-focused red light therapy products this fall. The company's advanced light conversion films employ low-cost blue LEDs to provide red light for phototherapy at a fraction of the cost of previous technologies. Recently, Light Polymers showcased a 660nm phototherapy red light film.
"Reasonably priced aqueous liquid crystal materials can be applied in numerous high-performance professional applications," said Ye Meijun, Asia Business Development Manager at Light Polymers. "High-end hotels are already reaching out to us, interested in installing related equipment to offer red light treatments to their guests."
Red light therapy has received FDA approval for use in the U.S., with NASA studies indicating its ability to relieve muscle tension, promote gum regeneration, reduce wrinkles, and heal sunburned skin. Light Polymers' red light products are available in sizes 300x600mm and 300x1200mm, designed with a modern consumer electronics aesthetic.
