Technical Principle: Spectral Selective Control—Scientifically Differentiating "Light" from "Heat"
Solar radiation can be classified into three main bands:
Ultraviolet (UV, 280–380 nm): Harmful to both human skin and indoor furnishings, UV radiation offers little to no benefit for lighting.
Visible Light (VIS, 380–780 nm): The primary source of light perceived by the human eye, visible light is essential for natural daylighting.
Near Infrared (NIR, 780–2500 nm): Carries significant thermal energy, making it the primary contributor to indoor temperature rise, yet it remains invisible to the naked eye.
Traditional Insulating Glass (e.g., Tinted Glass, Reflective Glass) often reduces temperature by absorbing or reflecting the entire light spectrum, resulting in a simultaneous decrease in visible light transmission. In contrast, LUCIH uses "Spectral Selective Filtration" technology, applying nano-scale materials to the glass surface to enable "selective penetration" across different wavelength bands:
Infrared Radiation Blockage > 85% – Effectively blocks near-infrared heat, preventing thermal energy from penetrating the glass and entering the interior.
Ultraviolet Radiation Blockage > 99% – Completely blocks UV radiation, safeguarding both human health and preventing indoor furnishings from fading or aging.
This technology functions much like an "optical filter", allowing only "useful light" to pass through while blocking "harmful heat", achieving precise physical separation.
Visible Light Transmission ≈ 70–80% – Maximizes natural daylight, reducing reliance on artificial lighting and enhancing both the brightness and visual comfort of indoor spaces.
Why Is Achieving "High Transparency + High Heat Insulation" So Challenging? How Does LUCIH Break Through This?
In the past, the heat insulation performance of glass often led to a reduction in visible light transmission or color distortion (e.g., glass turning green or blue), negatively impacting both architectural aesthetics and user experience.
LUCIH's breakthrough lies in three key innovations:
Nano-scale Coating: By precisely controlling the thickness and composition of the coating layer, LUCIH achieves precise regulation of the light spectrum.
Anti-reflection Design: Reduces light reflection loss, further enhancing transparency and improving visual clarity.
Thermal Stability and Durability: The coating undergoes high-temperature curing and environmental aging tests, ensuring that it retains its performance without degradation, even under prolonged exposure to sunlight and humid, hot climates.
Application Scenarios and Extended Benefits
1. Residential Spaces: Enhancing Quality of Life and Reducing Energy Bills
Large windows no longer mean the "oven effect." Children and the elderly can enjoy sunlight safely, without the risk of heatwaves.
Reduces the need for curtains or blinds, creating a more open and transparent space. Natural light helps regulate biological rhythms and supports mental well-being.
Long-term savings on electricity bills and air conditioning maintenance, with an estimated payback period of 3–5 years (depending on region and usage intensity).
2. Commercial and Retail Spaces: Boosting Employee Efficiency and Customer Experience
Studies have shown that natural light environments enhance work efficiency and concentration (Harvard T.H. Chan School of Public Health, 2018).
Reduces peak electricity demand, helping businesses meet their ESG (Environmental, Social, and Governance) and carbon-neutral goals.
3. Schools and Healthcare Institutions: A Key Material for Health-Oriented Design
Ample natural light in classrooms promotes eye health and helps stabilize students' emotional well-being.
Soft natural light in hospital wards accelerates patient recovery (research shows that exposure to natural light can shorten hospital stays).
UV radiation blocking protects medical equipment and pharmaceuticals from photochemical degradation.
LUCIH Energy-Saving Glass is more than just "a piece of glass." It is an integration of material science, optical engineering, and sustainable design. It redefines the relationship between architecture and natural light—not forcing a choice between "brightness" and "coolness," but providing both simultaneously. Every window becomes the starting point for energy savings, a gateway to comfort, and a bridge to nature.
