Chip-ul LED COB profesional de 7W cu diametru de 26mm este o sursa de lumina compacta si eficienta, potrivita pentru corpuri de iluminat, sisteme de iluminat spot sau casete luminoase de reclama. Tehnologia COB (Chip-on-Board) asigura un flux luminos uniform de pana la 810 lm, cu un randament de 140-150 lm/W, la o temperatura de culoare alba-rece de 6000-6500K.
Ce obtii cu acest produs
- Iluminare uniforma si fara puncte moarte — pastila COB de 19mm cu gel de protectie distribuie lumina omogen pe toata suprafata activa
- Randament ridicat de pana la 150 lm/W — consumi 7W si obtii pana la 810 lumeni, reducand costurile energetice in aplicatii continue
- Suport termic integrat din aliaj de aluminiu — disipa caldura eficient prin fantele radiale, prelungind durata de viata a chip-ului
- Compatibil cu o gama larga de proiecte — potrivit pentru corpuri de iluminat DIY, sisteme spot, casete de reclama si prototipuri electronice
- Indice de redare a culorilor Ra peste 80 — culorile obiectelor iluminate sunt redate natural si fidel
- Conectare simpla cu patru contacte clare — doua pozitive si doua negative, marcate pe suport, fara risc de confuzie
Cum functioneaza si cum se instaleaza
Chip-ul LED COB 7W se alimenteaza direct la 21V DC cu un curent de 300mA printr-un driver LED compatibil, conectand corect polii marcati pe suportul de aluminiu. Montarea se face prin lipirea chip-ului pe un radiator suplimentar sau pe o suprafata metalica cu pasta termoconductoare, obligatorie pentru disiparea caldurii generate la putere mare. Nu se conecteaza direct la retea fara driver si nu se expune la umiditate sau surse de caldura excesiva.
Intrebari frecvente
Ce driver am nevoie pentru acest chip LED COB de 7W?
Este necesar un driver LED cu iesire de 21V DC si curent constant de 300mA, dimensionat pentru o putere de cel putin 7W.
Chip-ul are nevoie obligatoriu de radiator sau merge fara?
Da, radiatorul si pasta termoconductoare sunt obligatorii. La 7W, chip-ul genereaza caldura semnificativa care, fara disipare corecta, reduce durata de viata sau poate deteriora componenta.
Se poate folosi acest LED COB in exterior sau in spatii cu umiditate?
Nu. Chip-ul nu are protectie IP declarata si nu este recomandat pentru medii umede sau expunere directa la intemperii fara o carcasa etansa suplimentara.

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.
