JY-UnSa050 uniform adjustable extended light source is a uniform adjustable extended light source specially designed for the display industry. This product integrates 6 spectral channels of LED light source group inside the integrating sphere as the light-emitting system, and realizes the isochromatic temperature of the output light illuminance at CCT=3000K, 4500K and 6000K. The light source can be adjusted continuously. The product includes two parts: the integrating sphere host and the electric control box. The LED light source with 6 spectral channels built into the integrating sphere is combined into the LED integrating sphere light source. The electric control box uses PWM control method through the USB interface to control the output color temperature and uniform light illuminance of the integrating sphere light source. The light illuminance at the opening of the LED integrating sphere is quickly and continuously adjustable, the output uniformity can reach more than 98%, and the light source stability can be controlled within ±0.5%. The product is equipped with a high-performance self-made spectrometer and factory calibration software. The spectrometer can be calibrated online, and it can also communicate with and control the CL-500A spectrophotometer to achieve the automatic calibration function of the product's illuminance and color temperature output, ensuring that users can use products with long-term stability during the application process. This product can provide customized color temperature and illuminance range according to customer needs, and can also match customized size spots.
