Replacement LED chips

Comments

    Just buy another 'lamp'. If the LEDs are no longer working, there is clearly a design issue (e.g. they are being driven too hard or exposed to water etc.). If you have genuinely replaced chips before (involving soldering etc.) then you should have no trouble sourcing equivalent LED replacements through the usual channels.


    But just replace the lamp altogether...

    Those are SMT/SMD (surface mount technology) LED's with various pin configurations. They come on reels from most suppliers, but you'd need to know the electrical characteristics and pin layout of the lamp before ordering suitable replacements.

    Normally you measure the supply voltage across the series of LED's and this help understand the wiring configuration. For example, if you had six LED's in series and the supply voltage was 24v, then the supply per LED is 4v. You would then match that with the parameter called the "forward voltage" or "Vcc" on the spec-sheet.


    Usually binning the product once it has failed is the intent of the suppliers though, most of these can't be repaired. 😣

    If replacing I'd buy separates so that went one component fails, I only have it to replace. These things never last near their quoted lifetime.
