Chip LED COB 20W alb-cald pentru proiectoare si spoturi
Pastila LED tip COB de 20W cu lumina alb-cald (3000-3500K) este componenta ideala pentru inlocuirea sau constructia proiectoarelor LED, spoturilor si lampilor de putere medie. Formatul COB (Chip on Board) asigura un flux luminos uniform de 2000-2100 lm dintr-o sursa compacta de 43x43 mm. Este alegerea potrivita pentru electronistii si tehnicienii care repara sau asambleaza corpuri de iluminat LED.
Ce obtii cu acest produs
- Lumina calda, confortabila, de 3000-3500K — potrivita pentru spatii rezidentiale, ateliere si zone de ambient unde lumina rece ar fi obositoare
- Flux luminos de 2000-2100 lm la doar 20W consumati — raport eficienta/putere ridicat pentru un chip de aceasta dimensiune
- Constructie COB compacta (43x43 mm) — se integreaza usor in proiectoare standard sau in constructii proprii fara modificari majore ale cadrului
- Tensiune de alimentare stabila de 32-34V DC — compatibila cu driverele LED de putere medie disponibile pe piata
- Inlocuire rapida a chipului defect — prelungesti durata de viata a proiectorului fara sa achizitionezi un corp intreg
- Component de uz general OEM — utilizabil in aplicatii de iluminat industrial, comercial sau DIY la un cost redus per lumen
Cum functioneaza si cum se instaleaza
Chipul LED COB se lipeste sau se fixeaza mecanic pe un radiator metalic adecvat, iar termopasta trebuie aplicata intre chip si radiator pentru disiparea caldurii — fara racire corespunzatoare durata de viata scade semnificativ. Conectarea se face direct la un driver LED cu iesire de 32-34V DC si curent corespunzator puterii de 20W; nu se alimenteaza direct la retea. Operatiunea necesita cunostinte de baza in electronica — lipire, identificarea polaritatii si utilizarea unui driver LED adecvat.
Intrebari frecvente
Ce driver LED este compatibil cu aceasta pastila de 20W?
Ai nevoie de un driver LED cu tensiune de iesire 32-34V DC si curent de aproximativ 600-650mA, astfel incat puterea totala sa se incadreze in 20W.
Am nevoie de radiator pentru acest chip COB?
Da, radiatorul este obligatoriu. Fara disiparea caldurii, chipul se deterioreaza rapid; se recomanda un radiator dimensionat pentru minimum 20W si aplicarea termopastei.
Poate inlocui chipul dintr-un proiector LED de 20W existent?
In general da, daca dimensiunile fizice (43x43 mm) si tensiunea driverului existent (32-34V) corespund; verifica intotdeauna specificatiile proiectorului inainte de inlocuire.

Inspired to create a chair where the back and arms are moulded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Inspired to create a chair where the back
Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The moulded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
