Simple dual color temperature fill light

I got 3D printing coupons from a previous event. If I can't use them all, I'll make a small fill light.
I've been lazy lately, so I'm too lazy to write programs, so I'll make a pure hardware version of the small light.
With the shell, the light board and the main board are all 1.2mm thick.
 
1) Lithium battery power supply, IP5306, 5V2A charging.
2) TD8203A boost LED driver. Potentiometer and op amp combination analog dimming. Power 2.7W×2.
3) The op amp is used as a comparator for voltage indication and LED overheat protection, reducing the current by about 3/4.
 
 
 
 
3D shell, manually embedded nuts. The frosted acrylic panel was also made last time.
 
 
 
The copper column is M2×3+3, and the screw is M2×5.
 
The FPC cable is reverse 16PIN 1mm and 6cm long.
 
 
 
 
The reverse magnet is 12*4*2.
