Chip LED COB 7W dual-culoare pentru proiecte de iluminat
Chip-ul LED COB 28mm cu putere de 7W integreaza doua temperaturi de culoare pe acelasi suport — alb rece (6000-6500K) si alb cald — permitand utilizarea independenta sau combinata a acestora. Tehnologia COB injectata asigura un flux luminos omogen de pana la 770 lm, potrivit atat pentru proiecte DIY cat si pentru aplicatii profesionale de iluminat. Substratul din aliaj de aluminiu cu fante radiale disipa caldura uniform, prelungind durata de viata a componentei.
Ce obtii cu acest produs
- Flexibilitate de iluminat — utilizezi alb rece, alb cald sau ambele simultan pentru a obtine o lumina neutra, fara a schimba componenta
- Flux luminos ridicat pentru dimensiunea compacta — 700-770 lm dintr-un chip de 28mm, eficient energetic la 100-110 lm/W
- Montaj versatil — cele patru contacte de alimentare (2+ si 2-) permit integrarea simpla in circuite existente sau proiecte noi
- Disipare termica eficienta — suportul din aluminiu cu fante radiale reduce riscul supraincalzirii cand este aplicata pasta termoconductoare
- Indice de redare a culorilor Ra peste 80 — culorile iluminate apar naturale si clare, util in aplicatii comerciale sau de expunere
- Compatibil cu o gama larga de aplicatii — spoturi incastrate, proiectoare, casete luminoase, corpuri de iluminat auto-moto, ambarcatiuni, camping
Cum functioneaza si cum se instaleaza
Chip-ul LED COB 7W se alimenteaza la 21-22V DC cu un curent de 280-300mA printr-un driver LED compatibil — nu se conecteaza direct la retea. Inainte de montare, aplicati un strat subtire de pasta termoconductoare intre chip si radiatorul pe care il fixati, pentru a asigura transferul termic corect. Conectati polii pozitivi si negativi conform marcajelor de pe substrat, respectand polaritatea indicata.
Intrebari frecvente
Am nevoie de driver separat pentru acest chip LED?
Da, chip-ul necesita un driver LED care sa furnizeze 21-22V DC la 280-300mA. Nu se poate alimenta direct la 220V fara driver.
Pot folosi doar una dintre temperaturile de culoare, nu ambele?
Da, cele doua circuite sunt independente. Conectezi doar perechea de contacte corespunzatoare temperaturii dorite — alb rece sau alb cald — sau ambele pentru lumina neutra.
Este obligatorie pasta termoconductoare la montaj?
Este obligatorie. Chip-ul de 7W genereaza caldura semnificativa; fara pasta termoconductoare si un radiator adecvat, durata de viata scade dramatic si riscul de defectare creste.

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.
