BBA solar simulator is a high-performance optical device used to simulate solar radiation, which is widely used in solar panels, photovoltaic materials, coatings, plastics and other fields.
The light source used in the BBA-class solar simulator is a xenon lamp, and its main parameters include light source power, light source life, spectral range, etc. Among them, the light source power refers to the optical power output by the light source, which is usually 2kw or 3kw. The life of the light source refers to the time that the light source is used, usually more than 1000 hours. The spectral range refers to the range of wavelengths of light output by a light source, usually 300 2500nm.
Optical system parameters.
The optical system of the daylight BBA-class solar simulator is composed of mirrors, lenses, filters, etc. Among them, mirrors are optical elements used to reflect light onto lenses, and their reflectivity is usually more than 95%. A lens is an optical element used to focus light, and its focal length is usually 1m or 15m。Optical filters are optical components used to adjust the spectral range, usually including the three bands of UV, VIS, and IR.
Control system parameters.
The control system of BBA-level solar simulator mainly includes temperature control system, light intensity control system, spectrum control system, etc. Among them, the temperature control system is used to control the temperature of the light source and optical system to ensure the stability and accuracy of the equipment.
The light intensity control system is used to adjust the power of the light source to control the light intensity.
The spectral control system is used to adjust the position and angle of the filter to adjust the distribution of spectral range and light intensity.
Performance metric parameters.
The performance indicators of the solar BBA solar simulator include spectral matching (standard AST, E927-05), spectral matching degree (standard JISC 8912), time instability (standard IEC60904-9 2007 ED2), etc. Among them, light intensity refers to the amount of light intensity output by the device, which is usually 1 2 suns. Spectral matching refers to the degree to which the spectrum output by the device matches the solar spectrum, usually am15g。Uniformity refers to how evenly the light intensity distribution of the output of the device is, typically 5%.
Daylight BBA solar simulator is a high-performance optical device with good optical performance and stable performance. Its main parameters include light source parameters, optical system parameters, control system parameters and performance index parameters. Understanding these parameters is important for proper use and maintenance of the equipment.
