Design custom UV LED PCB

Hello expert

I am looking for someone who could help me with this project:

I want to design PCB for wire and wireless UV nail lamp with these requirements:

1. Supply by 24V 90W external dc adapter

2. 32 parallel LEDs 3.3V, 700mA max current, devised in 2 groups. For them to work stable, they need supply by constant voltage, constant current( adjustable by potentiometer as I might use different type and layout of LEDs later)

3. 12.6V outlet connector for li-ion battery

4. Main on/off switch

5. IR sensor to on/off LEDs when hand in

6. 4 sensors for choosing time such as 30s, 45s, 60s, 90s

7. LEDs can work at 350mA or 700mA so I need a button/switch to choose.

8. Display: can be either 2 digits 7 segment with battery status bar or 2.8” lcd monitor that can show battery status as well.

9. 1 power connector for 5V cooling fan

10. Size of pcb 120mm(+20mm)x50mm(+10mm)

I am looking forward for speaking with you soon. Please email me at tadao85@[login to view URL]
