The P-T6001200 ultra-slim fixtures, with a thickness of only 36 mm, were applied in areas with stricter ceiling constraints, ensuring a clean and modern visual appearance without compromising lighting performance.   Both lighting systems work together seamlessly, offering stable control, smooth dimming, and consistent light quality across different zones.         Project Results The completed lighting system significantly improves spatial openness and visual comfort.  The experience center now features bright, soft, and evenly distributed light, creating an environment that closely resembles natural daylight. This project demonstrates the flexibility and reliability of sky lighting solutions in international commercial and experience-based spaces.   Our company focusing on the lighting technology of Rayleigh scattering optical phenomenon, using white LED-precision micro-optics - nano scale material technology -IOT algorithm to simulate the 24-hour automatic change process of sunlight, and highly restore the natural scene of sunlight shooting into the room from thousands of miles high.   The clear blue sky and warm sunshine into the indoor lighting, widely used in insufficient lighting space or easy to continuous rain and snow in the longitude and latitude area.  

The Origin of Rayleigh Scattering-Why the Sky Appears Blue 1. What Is Rayleigh Scattering? Rayleigh scattering is a physical phenomenon that describes how light interacts with very small particles.   It was first explained in the 19th century by British physicist John William Strutt (Lord Rayleigh). His work showed that when light passes   through a medium containing particles much smaller than the wavelength of light—such as gas molecules in the atmosphere—the light is   scattered rather than traveling in a straight line.   This type of scattering is especially important in understanding how sunlight behaves in Earth’s atmosphere.     2. How Sunlight Interacts with the Atmosphere Sunlight reaching Earth appears white, but it is actually a mixture of many different colors, each with a different wavelength.   When sunlight enters the atmosphere, it encounters countless tiny gas molecules, primarily nitrogen and oxygen. These molecules are far smaller than visible light wavelengths, which makes Rayleigh scattering the dominant effect.   A key characteristic of Rayleigh scattering is that shorter wavelengths scatter much more strongly than longer wavelengths. In simple terms:         Blue light has a short wavelength Red light has a longer wavelength Short wavelengths are scattered far more efficiently 3. Why the Sky Looks Blue Because blue light is scattered strongly in all directions, it spreads across the entire sky.   No matter where you look during the daytime, scattered blue light is reaching your eyes from every direction.   Longer wavelengths, such as red and orange light, pass through the atmosphere more directly and are less scattered.   As a result:       The sky appears blue during the day The sun itself appears slightly yellowish rather than pure white 4. Why the Sky Is Not Purple Although violet light has an even shorter wavelength than blue light, the sky does not appear violet for several reasons:     Together, these factors make blue the dominant color we perceive.         Sunlight contains less violet light than blue light Human vision is less sensitive to violet wavelengths Some violet light is absorbed in the upper atmosphere 5. Why Sunsets and Sunrises Appear Red When the sun is low on the horizon, sunlight travels through a much longer path in the atmosphere.   During this long journey:   Most blue and green light is scattered away Red and orange wavelengths remain and reach the observer This is why sunsets and sunrises often display warm red, orange, and golden tones.          

Transforming the Crown Hotel Indoor Pool with the E6001200 Artificial LED Skylight Project Overview The Crown Hotel aimed to elevate its indoor swimming pool environment by introducing a brighter, more open, and emotionally engaging atmosphere. Although the pool was well-designed, the fully enclosed structure lacked natural daylight, making the space feel heavy and disconnected from nature.   To overcome this challenge, the hotel installed 15 units of the E6001200 Artificial LED Skylight, a large-format sky panel capable of simulating a vivid blue-sky effect. The goal was to create the feeling of swimming beneath a natural sky, regardless of climate or season.   Client Requirements The hotel management requested a solution that would: Recreate a realistic blue-sky experience in an enclosed indoor pool Deliver bright, uniform illumination suitable for large water surfaces Provide dynamic, natural-looking sky color transitions Offer flexible control over lighting scenes Integrate into the existing ceiling structure with minimal renovation Additionally, the hotel wanted the lighting system to adapt across different times of day and usage scenarios.   Professional Lighting Assessment Our team conducted a detailed lighting evaluation and identified several technical needs: High ceilings and a wide pool area required long-distance, high-output illumination The project needed wide-range color temperature control to simulate different sky moods Target brightness levels of 300–500 lux across the water surface Ability to maintain consistent color performance in a humid, chlorine-heavy environment A lighting system that could automatically adjust for different scenes and guest experiences The E6001200 skylight model was selected because it meets all of these requirements with its: 2100K–7500K wide color temperature range Automatic brightness and color adjustment High lumen output and realistic sky gradients Large 600×1200 mm light-emitting surface Solution & Implementation Product Configuration Model: E6001200 Artificial LED Skylight Quantity: 15 units Color Temperature Range: 2100K–7500K (fully adjustable) Control Features: Automatic brightness + color adjustment, multiple sky-scene modes Installation Layout: Evenly distributed across the central pool ceiling Primary Scene: Blue-sky ambient mode with dynamic sky tone transitions Why the E6001200 Was the Ideal Choice Wide 2100K–7500K CCT range allows simulation of sunrise, daylight sky, and evening tones Automatic color and brightness adjustment creates lifelike sky transitions throughout the day High-power optical engine ensures uniform illumination across a large pool surface Realistic blue sky gradients enhance visual depth and emotional atmosphere Built to withstand high humidity and long daily operating hours Installation Process Our engineering team provided full support: Ceiling cut-out drawings & load-bearing guidance Wiring and power management planning On-site installation coordination with the hotel renovation team Final system tuning for sky effect realism Setup of dynamic brightness + color automation mode The installation was completed smoothly without affecting the hotel’s operations.     Project Outcome A True “Blue Sky Swimming” Experience The indoor pool now features a refreshing and immersive sky-like atmosphere. Thanks to the skylight’s 2100–7500K dynamic adjustment, the lighting can transition between: soft sunrise tones bright midday blue sky warm evening ambiance The visual effect creates the sensation of openness and natural daylight, dramatically improving guest comfort. Visual & Functional Improvements Water reflections combined with sky-blue lighting produce an outdoor pool illusion The space appears significantly more open and uplifting Guests report higher comfort and satisfaction Lighting level now reaches uniform 300–500 lux, ideal for pool activity Client Feedback “Our guests love the new sky lighting. It feels like swimming under a natural blue sky. The flexibility of brightness and color adjustment makes the entire pool experience much more relaxing and enjoyable.”   Conclusion The Crown Hotel indoor pool transformation demonstrates the powerful impact of the E6001200 Artificial LED Skylight.
