Got broken LED screens for SAD lights

I had seen a great Youtube video on how to make cheap SAD lights.'

So did the same :)

Might be able to use existing PSU for large screen.

Googled "LED strip JLD320B1235"

So 3V each element is that 3V x 22 x 2W or 33V x 2 or 66V ?
Best try 3v battery first :)

Product Description
Backlight strip production information
1.Consistent with the original, Brand New, no need to modify it, easy to install
2.Long operating life, typically lasting over 100,000 hours
3.Brightness is consistent with the original, brightness up to 700 nits
4.Product length: 575 mm( length) * 10mm (width) * 1.0 mm (height) , 11 LED Lamps
5.Voltage: 0-94V, Single lamp voltage is 3V

(19:34) Excellent so how do I provide 66V at (2W a lamp) so 44W is 750mA.


(20:51) Can I get 90V at 200W from the old PSU?

Got cct diagram :)

The MAP3249 (U2) takes VIN pin 16 (12v) and EN pin 5 (driven by BKL_ON/OFF which is pin 5 of CN4) and is active high.
It also takes PWM pin 14 (6v max, TTL levels, 100 to 2KHz) (driven by PWM_DIM which is pin 7 of CN4) and ADIM pin 3 (driven by V_ADIM which is held at 2.6v by voltage divider from V_REG (which is VLDO pin 1 of U2)

GATE pin 13 becomes GATE_CON and controls Vled
CS pin 12 becomes CS_CON and also controls Vled

CN6 only Vled pin 1 and CH_4 pin 7 (55v max) are used by wired connection lead. Is this 24v to the LEDs?

Will try it tomorrow with a NodeMCU providing the PWM will then upgrade my Solar Pump NodeMCU code so if it doesn't get a command in 10 mins it takes control and goes into safety mode!
