I have got a LED grow light which has got 2 LEDS which has gone open and resulted in one half of the light not turning on.
The whole light consists of 60 x 10W leds. 30 leds are grouped together and powered from one power supply.
First of all I couldn't find any 10W leds locally and it seems that its hard to come by online as well. Only leds I could source locally are 1W to 3W which presumably I couldn't interchange.
There are diodes paralleled with the Leds, I'm not sure what they really are but looks they are 3V Zeners. The diodes which were paralleled with the two dead Leds also were burnt.
I was thinking of bypassing the two empty slots with jumper wires, would this be a good idea? I have seen that done on backlights of LED tvs. I am not too concerned with having two brightness levels. Instead of jumper wires should I use resistors? If so what value should I use. The voltage output of the power supply is 95V (I know these controller would be constant current sources).
Thanks for the help in advance.
P.S: Could you please advise on soldering/desoldering these leds. The whole body seems to be soldered along with the two legs. I am able to desolder the two legs however when trying to remove the body it the whole LED disintegrates leaving the metallic part soldered. I tried with my hot air station and had no luck the plastic cover disintegrates and to take the metallic part I had to tap with a screw driver. (Refer to photo 2)
