Chip LED COB 5W 28mm cu lumina calda sau rece
Chip-ul LED COB 5W cu diametru de 28mm este o sursa de lumina compacta si versatila, conceputa pentru proiecte de iluminat profesional sau DIY. Modulul 2-in-1 permite functionarea cu temperatura de culoare alb-rece, alb-cald sau ambele simultan, obtinand astfel lumina neutra. Substratul din aluminiu cu fante de prindere asigura disiparea eficienta a caldurii si durata lunga de viata.
Ce obtii cu acest produs
- Flexibilitate maxima in proiect — chip-ul 2-in-1 functioneaza independent pe alb-rece, alb-cald sau combinat pentru lumina neutra, fara componente suplimentare
- Flux luminos ridicat pentru dimensiunea mica — 500-550 lm la doar 5W, cu eficienta de 100-110 lm/W, potrivit pentru spoturi, proiectoare si corpuri de iluminat
- Durata de viata de pana la 20.000 de ore — inlocuiesti rar si economisesti pe termen lung
- Substratul din aliaj de aluminiu cu fante radiale disipeaza caldura uniform, protejand chip-ul si mentinand performanta constanta
- Indice de redare a culorilor Ra peste 80 — culorile sunt redate corect si natural, util in iluminatul comercial, hotelier sau de birou
- Compatibil cu o gama larga de aplicatii — spoturi incastrate sau aparente, casete luminoase, lampi auto-moto, proiectoare, iluminat ambiental sau industrial
Cum functioneaza si cum se instaleaza
Chip-ul LED COB se alimenteaza la tensiune continua de 15-16V DC printr-un driver compatibil, prin cele patru contacte de alimentare (2 pozitiv + 2 negativ) marcate pe substratul metalic. Montarea se face prin lipire sau fixare mecanica pe un radiator, cu aplicarea obligatorie a pastei termoconductoare intre chip si suprafata de racire. Nu necesita scule speciale, insa este importanta respectarea polaritatii si asigurarea racirii corespunzatoare pentru a evita supraincalzirea.
Intrebari frecvente
Ce driver am nevoie pentru acest chip LED COB de 5W?
Este necesara o sursa de curent constant (driver LED) care furnizeaza 15-16V DC la un curent de 280-300mA. Nu se conecteaza direct la retea sau la surse de tensiune variabila.
Pot folosi chip-ul doar pe o singura temperatura de culoare, nu pe ambele?
Da, modulul 2-in-1 permite alimentarea independenta a canalului alb-rece sau alb-cald, in functie de contactele la care conectezi driver-ul.
Este obligatorie pasta termoconductoare la montaj?
Da, aplicarea pastei termoconductoare intre chip si radiator este obligatorie. Fara ea, temperatura de jonctiune creste rapid si durata de viata a chip-ului scade semnificativ.

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.
