Abstract

A novel design of LED mixing color based on improved artificial fish swarm algorithm (AFSA) was proposed. In order to improve convergence rate and accuracy of AFSA

opposition-based reinforcement learning was utilized to optimize solution space of AFSA

Normal and Cauchy distribution function were employed as adaptive weight operators to optimize vision field and step-size. The white

amber and blue LEDs were chosen to design LED lamp samples. LED proportions of 4 000 K color temperature among those LEDs were optimized by AFSA and new AFSA in the Matlab. Simulations indicate that improved AFSA has the higher convergence rate and accuracy. After LED lamps were tested by integrating sphere

the results show that the difference between the actual value and simulation calculation value is tiny

and the improved AFSA is effective. The improved AFSA provides a new efficient method for the calculation of LED proportions. Compared with the traditional method

the new method not only saves a significant amount of time

but also achieves higher luminous efficacy for lamps. All these show that the new method is effective and has high practical value.
