Overview
LED solar simulator, photovoltaic solar simulator LED adopts low-voltage constant current drive, which is safer, more reliable, and easy to maintain without risk. Each group of LED beads is controlled by an independent constant current source, and the light intensity can be adjusted by adjusting the current intensity as a whole.
Product Details
The LS-LED-AAA series LED solar simulator is an ideal solar simulation light source for scientific research. The LED solar simulator uses LEDs with wavelengths ranging from 350nm to 1100nm as the light source. After spectral fitting, mixing, and homogenization, it forms a solar simulator that meets 3A level requirements.
The full name of LED is light emitting diode, which is a semiconductor device that can emit light when current flows through it. Electrons in semiconductors recombine with electron holes to release energy in the form of photons. The use of LED as the light source for solar simulators has the following advantages.
1Photovoltaic solar simulatorProduct Features
1. Long service life
|
| Feature: Long service life Description Thanks to the inherent long lifespan of LEDs, coupled with good heat dissipation design and temperature control algorithms, the service life of LED light sources can reach 10000 hours without any consumables during use; |
2. A+level spectrum
|
| Feature: A+level spectrum Description According to the IEC60904-9-2020 standard, the A+spectral range is 0.875~1.125, and the actual measured data of LS-LED series products is 0.964~1.02, which is much higher than the A+standard |
3. Spectral stability
|
| Feature: Spectral stability Description The output spectrum of LED is not only related to the characteristics of the device itself, but also to the operating current and temperature. In the design process from LED chip packaging to the overall structure, how to achieve efficient heat dissipation is the primary consideration. With the excellent high-precision constant current source tuned, it fundamentally ensures the stable operation of the LED, making each segment of the LED output spectrum very stable. |
4. Spectral adjustability
|
| Feature: Spectral adjustable Description The IEC 60904-9 standard divides the solar spectrum into 6 spectral bands. The LS-LED series solar simulator can independently control the 6 spectral bands according to the standard, which can effectively play a role in the IV testing of multiple solar cells such as perovskite stacked solar cells; |
5. Built in light intensity feedback system
|
| Features: Built in light intensity feedback system Description Built in light intensity feedback system, real-time monitoring of irradiation intensity, dynamic adjustment of irradiation intensity using software algorithms, long-term irradiation instability less than 0.7%, meeting the requirement of time instability level A+ |
6. Continuous adjustment of light intensity
|
| Feature: Continuous adjustment of light intensity Description Each group of LED beads is controlled by an independent constant current source, and the light intensity can be adjusted by adjusting the overall current intensity; Continuous power regulation with a minimum of 1% can be achieved within the range of 100 to 1100 W/m2; |
7. Safe and reliable
|
| Features: Safe and reliable Description LED adopts low-voltage constant current drive, which is safer, more reliable, and easy to maintain without risk. |
