    the displayed diagram why was it too small

      You have the datasheet linked in the description. You can get the full-size chart there.

    i tryed a few lamps and output driver has 300 v dc. is that normal?

    • @TasteTheCode
      @TasteTheCode  2 ปีที่แล้ว +1

      Was that just the driver with no LEDs attached? If so then yes, cuz the LEDs are the ones that clamp the voltage to some level and the driver is usually set to deliver a set amount of current through them.

      @@TasteTheCode Thx. Tomorrow I'll try to disconnect only minus and then measure the voltage. That should be the right way I think or is there any other way?

    • @TasteTheCode
      @TasteTheCode  2 ปีที่แล้ว +1

      Nope, that should yield the exact same result. You shoud measure the voltage across the LEDs while connected but again it will be close to 250v I guess. These power supplies are designed to output steady current!

      @@TasteTheCode Thx. the lamps have 10w so 250v divided by 10 is 25 amp? smth is not right. 250v is very high voltage for 10-20 led chips.

    • @TasteTheCode
      @TasteTheCode  2 ปีที่แล้ว +1

      Those LEDs usually have more than 1 chip inside in series. So even if you look at one phisical LED, inside it might be 10 chips or even more.

    Honestly, 9/10 times you can just bodge across a dead LED and it'll work perfectly fine, the other LEDs may be running at a slightly higher voltage, but in that case it would only be a overvoltage of ~0.2v on each LED, in a 15 LED lamp like this one. The rest may run slightly hotter, but it'll almost definitely last the life of the rest of the lamp!

    • @TasteTheCode
      @TasteTheCode  2 ปีที่แล้ว +2

      Sometimes, yes, you can do that but from what I have seen, LEDs are run either at their max or sometimes even above that. Going further up can cause an avalanche where LEDs just die one after the other.

      @@TasteTheCode Thats true, although its likely either that or bodging a diode with a similar voltage drop across it.
