Plasma light source(LEP) leads technological innovation in solar simulators
When discussing solar simulators, most focus only on matching sunlight's intensity and color temperature, overlooking the most critical element - spectral range. This is precisely where xenon lamps and LED-based simulators fall short.
Plasma light sources, technically termed Light-emitting Plasma (LEP), represent the closest full-spectrum match to sunlight. Only three companies globally possess this core technology: one in the US, one in the UK, and China's CASM.
LEP covers 290nm-1800nm with continuous spectral distribution, matching noon sunlight's color temperature. Its spectral composition precisely mirrors solar radiation: 9% UV, 68% visible light (with identical red/green/blue ratios to sunlight), and 23% IR.
Despite its compact size (0.4 cm³), LEP delivers exceptional brightness - 25,000 lumens output, achieving 114,100 lux at 15cm distance and 28,000 lux at 120cm (equivalent to midday summer sunlight).
With irradiance exceeding 1000W/m² and intensity over 1.0 sun, LEP meets Class AAA standards for spectral match, stability, and uniformity in solar simulation.
Plasma light sources utilize electrodeless bulb technology, operating without flicker. With a 97 CRI rating, they exhibit minimal light decay — maintaining over 80% luminous efficacy after 50,000 hours of continuous use — while preserving stable color temperature throughout.
Superior to xenon lamps and LED technologies, plasma light sources represent the new generation of solar simulation.
CASM specializes in plasma lighting technology, inviting global lighting leaders for strategic partnerships.
