Optimum Design of LED Array Light Source Based on Fruit Fly Optimization Algorithm
In order to improve the illumination uniformity of LED array light source
a new way to design 3D LED arrays was proposed. At first
the formulas of LED array's illuminance on the target panel were derived and a mathematical model was then deduced in order to measure LED array's illumination uniformity. Then
a 2D circular LED array and a 2D square array were designed based on the way put forward by Ivan Moreno. The spatial positional parameters of the LEDs in the arrays were further optimized by the fruit fly optimization algorithm
and the standard deviation of illuminance on target panel was set as the taste concentration decision function of fruit fly optimization algorithm. The lower value the taste concentration decision function could obtain
the higher illuminance uniformity the optimized 3D LED array would have. The whole simulation process was carried on by the MATLAB software. In this way
the three-dimensional optimization of LEDs' locations in the arrays was accomplished
which made the illumination uniformity of the LED arrays much higher. At last
the TracePro optical software was adopted to imitate and test the illuminating effect of the optimized 3D arrays. The results of this experiment show that
after being optimized by the fruit fly optimization algorithm
the illumination uniformity of the optimized 3D circular LED array increased to 96.0%
which is 25.3% higher than the optimized 2D one
and that the illumination uniformity of the optimized 3D square LED array increased to 97.4%
which is 7.7% higher than the optimized 2D one. The results prove that this new optimization method is practicable
and compared to the traditional optimization methods
this new method is more efficient as the LED arrays are allowed to be optimized automatically by computer program
which greatly reduce the cost of time
material and manpower.
