We set the corresponding parameters use GO-2000A software and use the rotary table distributed photometer (Product Model: GO-2000A) to test its spatial light intensity distribution. The testing result is shown in Fig. 7. The isocandala diagram is shown in Fig. 8.

3. The choice switch for the red and blue light proportion
In order to make the best effect with the least cost, the project specially proposed the red blue light proportion choice switch,it can make the proportion of the red and blue light between in 4:1 and 9:1. As shown in Fig. 9. Put blue LEDs in the last two lamp beads in each parallel branch, in every series branch,the last LED can be selected by these switches in front of those last LED,it can be 5 red LED or 5 blue LED, so that you can control the switch open and close simply to control the proportion of red and blue LEDs.
