摘要：Studied on multiples color temperature LEDs as calibration light based on array, and designed a portable calibration light device with tunable color temperature which could simulate various luminous environment to test the performance of camera and sensor. The experimental carried on the light device. The results showed that the calibration light source could accurately reappear the color temperature light source in the range of 2500K to 6500K under the condition of multi channels constant power supply, and the precision of color temperature is within ±30K and the light is stable, the uniformity is within ±2.5%.
