II. Product Introduction
The BG-LED-AAA series LED solar simulator is an ideal solar light source for scientific research and industrial battery preparation. The LED solar simulator uses LEDs covering wavelengths from 350nm to 1100nm as the light source, which, after spectral fitting, mixing, and averaging, forms a solar simulator that meets 3A grade requirements.
LED, short for Light Emitting Diode, is a semiconductor device that emits light when an electric current passes through it. Electrons in the semiconductor recombine with electron holes, releasing energy as photons. Using LEDs as light sources for simulating sunlight offers the following advantages.
1. Long service life
| FeaturesLong service life Description： Due to the inherent long lifespan of LED technology, combined with excellent heat dissipation design and temperature control algorithms, the lifespan of LED light sources can reach up to 10,000 hours. |
2. A+Level Spectrum
| Feature: A+ Grade Spectral Description: • In compliance with the IEC60904-9-2020 standard, the A+ grade spectral range is 0.875~1.125. The actual measured data for the LS-LED series is 0.964~1.02, significantly exceeding the A+ grade standard. |
3. Spectrum Stability
| Feature: Spectral Stability Description: • The LED output spectrum is related not only to the inherent characteristics of the device but also to the working current and temperature. In the design process from LED chip encapsulation to the overall structure, achieving efficient heat dissipation is a primary consideration. Paired with a well-tuned high-precision constant current source, this fundamentally ensures stable LED operation, resulting in each segment of the LED output spectrum being highly stable. |
4. Continuous Intensity Adjustment
| Feature: Continuous light intensity adjustment Description: Each LED bead in a set is controlled by an independent constant current source, allowing adjustment of light intensity by simply regulating the overall current strength. • Achievable continuous power adjustment in increments of 1% within the range of 100 to 1100 W/m². |
7. Safe and reliable
| Features: Safe and Reliable Description: LED is driven by low-voltage constant current, offering enhanced safety and reliability, with easy maintenance and no risk.
