High-stable LED light source сconnected to the temperature stabilization unit

It is intended for storing, reproducing, and transmitting units of luminous intensity and luminous flux to subordinate measuring instruments. It has the following characteristics: ✦ Luminous flux of at least 1000 lux (without diffuser); ✦ Temperature control system based on the Peltier element; ✦ Correlated color temperature: 2800 – 3000 K, 3500 – 4500 K, 5000 – 6500 K. The temperature of the LED crystal is maintained at a constant level 20°C. Temperature stabilization units ensure the operation of Peltier elements. High-stable LED light source are made in two versions: ✧ for storing, reproducing, and transmitting units of luminous intensity and units of luminous intensity to subordinate measuring instruments; ✧ for storing, reproducing, and transmitting a unit of luminous flux to subordinate measuring instruments.
