An LED solar simulator is a type of solar simulator that uses light-emitting diodes (LEDs) as the light source to replicate the spectral distribution, intensity, and uniformity of natural sunlight in a controlled laboratory environment.
Key Features and Advantages
Precise Spectral Control: By combining LEDs of different wavelengths (e.g., UV, visible, near-infrared), the output spectrum can be finely tuned to match standard solar spectra such as AM1.5G (for terrestrial applications) or AM0 (for space). This enables excellent spectral match (Class A).
High Temporal Stability: LED sources provide extremely stable light output over time, resulting in outstanding temporal stability (often Class A or better), crucial for accurate and repeatable measurements.
Long Lifetime & Low Maintenance: LEDs have significantly longer operational lifespans (typically tens of thousands of hours) compared to traditional xenon lamps, reducing replacement frequency and maintenance costs.
Energy Efficiency & Low Heat Output: LEDs consume less power and generate much less heat than xenon arc lamps, minimizing sample heating and reducing cooling requirements.
Instant On/Off: LEDs reach full brightness instantly without warm-up time and can be switched off immediately, improving workflow efficiency and enabling pulsed operation if needed.
Eco-Friendly: No hazardous materials (like mercury in some lamps) and lower energy consumption contribute to a smaller environmental footprint.
Applications
LED solar simulators are widely used in:
Photovoltaic (PV) Testing: High-accuracy I-V curve measurement of solar cells and modules, especially for research on perovskites, organic PV, and multi-junction cells.
Material Durability Testing: Simulating sunlight exposure for aging studies of polymers, coatings, and textiles.
Photochemical Research: Experiments in photocatalysis, photobiology, and solar fuel generation.
Agricultural and Biological Studies: Controlled plant growth experiments and circadian rhythm research.
We are offering innovative LED triple A+ sun simulators for the direct integration into the production line and for stand-alone operation in the laboratory or in incoming goods department. Our LED sun simulators provide a best in class repeatability, a long pulse duration and low maintenance cost.
Our LED based light source is certified by TÜV Rheinland according to IEC60904-9 Ed.3 (extended spectrum) with A+A+A+. We can inspect modules up to a size of 1400 x 2750 mm and larger.
