3 Anti-Glare Techniques for Underwater LED Lights That 80% of Users Don't Know About
Underwater lights are typically installed beneath the water's surface; featuring a compact, refined design and LED light sources, they can emit a dazzling array of colors. Beyond providing illumination, they offer significant aesthetic appeal and are commonly found in private swimming pools, fountains, and park landscapes.
While appropriate lighting brings us pleasure, excessive light leads to "light pollution," making anti-glare capabilities an essential design feature for underwater lights. So, what unique anti-glare techniques are used in underwater lighting? Let's explore these methods today.
Layered refraction
For swimming pool lighting, the requirements are twofold: the light must not shine above the water surface, and it must also provide a wide illumination range.
The beauty of stratified refraction lies in its division of the lens into upper and lower layers: light refracted by the upper lens runs parallel to the water's surface, while light refracted by the lower lens disperses evenly-perfectly meeting the requirements.
Biomimetic honeycomb
Do you see this dense array of honeycomb-like lenses? These are also designed to prevent glare. They utilize biomimetic technology to create hundreds of tiny, honeycomb-structured lens elements on the surface.
As light enters the eye, hundreds of small, honeycomb-structured lenses reflect away intense glare and the scattered, stray light from object surfaces, converting the light into parallel and concentric beams; this prevents the eyes from being irritated by harsh light, thereby protecting them and alleviating eye fatigue.
Concave lenses cause divergence.
Leveraging this principle, the shades of many light fixtures are designed with curved surfaces; this significantly softens the intense light emitted by the LEDs and disperses the light, resulting in a wider coverage area and more uniform illumination.
