Introduzione

Anche se queste luci hanno una garanzia di tre anni, è più economico ripararle da soli che pagare le spese di spedizione per rispedire le luci. Ho comprato i LED T1 3/4 (5 mm) da Digikey, cercando qualcosa nella gamma da 800 mcd in su dei colori necessari. La scelta è ricaduta su:

404-1096-ND (rosso)

404-1097-ND (arancione)

C503B-BCS-CV0Z0461-ND (blu)

C503B-GCN-CY0C0791-ND (verde)

404-1092-ND (giallo)

I LED sono collegati in serie in gruppi - tre gruppi - a un filo. Se un LED nel gruppo è guasto, nessuno in quel gruppo si accenderà. Il trucco è scoprire quale (o quali) è difettoso.

È più facile se disponi di un filo anche parzialmente funzionante. In tal caso, rimuovi un LED dal filo buono e usa quella presa per testare ogni LED, uno alla volta, dal filo difettoso. Se il LED non funziona nel filo buono, sostituisci il LED secondo le indicazioni che seguono. Potrebbe essercene più di uno guasto, quindi dopo averlo sostituito, se il filo difettoso non si accende ancora, passa al LED successivo.

Se non hai un filo buono da usare per il test e non hai un altro modo per testare i LED, allora rimuovi ogni LED, uno alla volta, dal filo difettoso, e controlla i cavi per assicurarti che non siano rotti. Se sono rotti, sostituiscili, altrimenti rimetti il LED e passa al successivo.

    • Togliere i "bulbi" sfaccettati. Le coperture delle lampade colorate si staccano a scatto, alcune sono piuttosto rigide, ma escono fuori. Non si svitano.

    Help! We can't get the bulb off! Did you use tools? Do you have a video? Only our blue ones are out on 6 strings. Clearly a defect of some kind in these 6 tear old strings that have inky been used twice. Ugh!

    • Rimuovi LED e relativo attacco. Nei fili che ho, ce n'erano due stili diversi non intercambiabili.

    • Nota che la presa è sagomata - può entrare nella presa solo in un modo.

    • Rimuovi il LED difettoso dalla presa, in modo da poterla riutilizzare. Nota che il nuovo LED ha una gamba più lunga dell'altra.

    • Il terminale lungo va nel lato della presa con la tacca come mostrato in figura.

    • La lampadina del LED potrebbe non posizionarsi perfettamente, ma non fa niente, resterà sotto il coperchio della lampadina sfaccettata in plastica.

    • Piega i terminali e tagliali.

    • Prova la lampadina nel filo "buono" se ne hai uno. Se funziona, inseriscila nel filo difettoso e vedi se questo ha risolto il problema. Se non funziona, sai che il LED è buono ora, quindi passa al prossimo.

    Tryed the bulbs you show here, They are way too brite! after many Hr looking found concave LEDs at LighthouseLEDs.com they were perfect. Not as cheap but just like the one’s in my Decorations.

    Tips: Either use a multimeter or use a CR2032 battery to test the LED before soldering in :)))

    What do you do when you have checked all the bulbs in the bad strand and all the bulbs are good?

    hutcheson4454 -

    I ran into this once, too. In my LED lights, there is a potted blob of plastic, one per section, that doesn’t open. I used a dremel tool to get into it (ground away enough of the plastic, and found a high-wattage resistor in there, and maybe a backwards diode? I don’t remember. I replaced the resistor and potted the whole thing up again with Sugru, and it worked. Sorry I didn’t record the value of the resistor or take pictures.

    Are the short stubby LED’s that you are trying to replace no longer made? I have the same string of lights that I bought from Costco several years back that I can’t find. I don’t even know where to look for the caps.

    Louie Grajeda -

    Did you ever find replacements???

    Cindy Wilde -

    I'd love to find replacement bulbs in another color. Anyone find a place to buy them?

Hi! Can you tell me the difference between the two types of light bases you show above? The situation I have is I bought a set of the clear LEDs figuring we could get replacements since my husband prefers the colored ones. But, once we started pulling them apart, we found the different sized bases and the only replacement ones I could find had the short stubby base. Are they interchangeable if we pull the bulb out of the base? Do you have any suggestions for us? Thanks for any help!

The reason for the two different size sockets is that if you look at your strand, every so many lights three wire come into the socket instead of two. I think (and this is only a hypothesis) than the shorter sockets are to allow room for the connection of the third wire. Why they didn't just use short sockets for everything I don't know. But it seems likely to me that the short one would work everywhere. I have not tried it.

Thanks so much for posting this guide! My outdoor light strings are far from waterproof and I live in a rainy climate (yes, even in December), so my original LEDs corroded badly and the strings stopped working.

I ordered a whack of replacement LEDs using the reference numbers you provided. Replacement was simple. The results were spectacular -- better than I had dared hope. For $10 and a few minutes work, I kept $200 worth of strings from getting tossed. Thanks a bunch!

I've been using LED Christmas lights in many forms for a decade now, and I have NEVER seen replacement bulbs sold for any of them.

The rest of this I could have figured out on my own, but where do you get your replacement bulbs?

Dr H -

Any tricks to getting the faceted lamp covers off - or back on (which is harder, in my experience)?

pfedorch -

I am struggling to find the replacement clear fuse bulb, the one with the long stem. Any ideas where i can order from?

dee 05 -

I need replacement led bulbs. Anyone have any ide where to het them.? I have plain but no fuse ones.

dee 05 -

How can you tell which one is burned out??

michaellafrance_39 -

what if you have tried your bulbs from the bad strand and they all show to be good? What would be my next step?

hutcheson4454 -

Thank you very much for this useful instruction, but I think the led strip light is more practical. I've recently started to use different LED lights, and I've noticed that they are very nice to light up a room and it's also economical. I do not know more practical and pleasing to light the room at the moment. If you have the opportunity to try the led strip light, I glued it to my bathroom mirror, and now I am very comfortable shaving, as the light from the strip is good.

What are the little things with light like a battery

danielle king -

any body know the working voltage of the LED's ?
