Chip LED COB 3W alb-rece pentru proiecte de iluminat
Chip-ul LED COB 3W cu temperatura de culoare 6500K ofera o lumina alba rece, curata, potrivita pentru inlocuirea surselor de lumina in corpuri de iluminat, proiectoare mici sau aplicatii DIY electronice. Pastila COB de 11mm este montata pe suport din aliaj de aluminiu cu rol de radiator, asigurand disiparea caldurii si prelungind durata de viata a componentei. Cu un flux luminos de 390 lm la doar 3W consumati, acest chip ofera un raport eficienta-pret foarte bun pentru constructori si reparatori.
Ce obtii cu acest produs
- Lumina alba rece la 6500K — ideal pentru iluminat tehnic, atelier sau inlocuire spot, fara nuante galbui
- 390 lm flux luminos la 3W consum — eficienta energetica ridicata pentru dimensiunile reduse ale chipului
- Suport radiator din aliaj de aluminiu integrat — disipeaza caldura uniform, pastila nu se supraincalzeste in utilizare normala
- Pastila COB cu gel de protectie — rezistenta mecanica sporita, suprafata emitenta protejata impotriva umezelii si prafului
- Patru puncte de contact (2+ / 2-) — conexiune sigura si stabila, compatibila cu drivere standard de 9-11V DC
- Dimensiune compacta de 20mm — se integreaza usor in corpuri de iluminat existente sau in proiecte custom cu spatiu limitat
Cum functioneaza si cum se instaleaza
Chipul LED COB 3W se alimenteaza direct de la un driver DC cu tensiune intre 9V si 11V si un curent de 300mA — nu functioneaza conectat direct la retea fara driver. Montarea se face prin lipire pe radiator sau fixare cu surub prin gaurile suportului de aluminiu, urmata de conectarea celor doua fire de alimentare la bornele marcate + si -. Nu este necesara experienta avansata, insa se recomanda folosirea pastei termice intre chip si radiatorul extern pentru transfer optim de caldura.
Intrebari frecvente
Am nevoie de driver separat pentru acest chip LED COB?
Da, chipul necesita un driver DC care sa furnizeze 9-11V si 300mA. Nu se conecteaza direct la 220V fara driver.
Se incalzeste mult suportul de aluminiu in timpul functionarii?
Suportul din aliaj de aluminiu ajuta la disiparea caldurii, insa pentru utilizare indelungata se recomanda montarea pe un radiator suplimentar si aplicarea pastei termice.
Poate inlocui un bec de 3W dintr-un spot existent?
Da, cu conditia ca driverul existent sa fie compatibil cu tensiunea de 9-11V DC si curentul de 300mA. Verifica parametrii driverului 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.
