# Dayluxa

Dayluxa is an advanced fiber optic daylighting system that captures real sunlight using Fresnel lens solar tracking technology and transmits it indoors through high-purity quartz optical fibers.

The system enables natural daylighting in buildings without windows or with limited natural light, such as basements, hospitals, laboratories, aquariums, and large commercial facilities.

## Core Technology

Dayluxa uses:
- Fresnel lens solar concentrators (100mm diameter per lens)
- GPS + astronomical dual-axis solar tracking system
- High-purity low-OH quartz optical fiber transmission
- Hybrid lighting system with LED backup for non-sunlight conditions

The system continuously tracks the sun and maximizes sunlight capture efficiency throughout the day.

## Selection Guidance

System selection depends on:
- Indoor area size (m²)
- Required illuminance level (lux)
- Distance of fiber transmission
- Application environment (hospital, industrial, commercial)

---

## Installation Notes

- Optical fiber bending radius must be ≥150mm
- Each lens must maintain clear solar exposure
- System should be installed on rooftop or unobstructed sunlight area
- Indoor terminals should be distributed according to lighting layout design
