Chip LED COB 3W 26mm pentru proiecte de iluminat
Chip-ul LED COB profesional de 3W cu diametru de 26mm ofera o sursa de lumina compacta, uniforma si eficienta, potrivita pentru constructia sau repararea corpurilor de iluminat, reclamelor luminoase si sistemelor personalizate de lumina. Tehnologia COB integreaza mai multe puncte luminoase intr-o singura pastila, eliminand efectul de "pete" si asigurand un flux luminos omogen de pana la 390 lm la un consum redus de energie.
Ce obtii cu acest produs
- Lumina alba rece uniforma fara pete sau puncte — tehnologia COB distribuie fluxul luminos egal pe toata suprafata pastilei de 19mm
- Eficienta energetica ridicata — pana la 150 lm/W, ceea ce inseamna mai multa lumina la acelasi consum fata de LED-urile clasice
- Suport radiator din aliaj de aluminiu inclus — disipare termica uniforma prin design circular cu fante, fara supraincalzire rapida
- Compatibil cu o gama larga de proiecte — corpuri de iluminat, reclame luminoase, casete de promovare si prototipuri DIY
- Pastila protejata cu gel — strat de protectie care reduce riscul deteriorarii mecanice a chipului LED
- Conectare simpla cu patru contacte — doua pozitive si doua negative, clar marcate pe suport pentru evitarea erorilor de polaritate
Cum functioneaza si cum se instaleaza
Chip-ul LED COB 3W se alimenteaza la 9V DC cu un curent de 300mA printr-un driver LED corespunzator — nu se conecteaza direct la retea fara driver. Montarea se face pe suportul de aluminiu inclus, folosind obligatoriu pasta termoconductoare intre chip si radiator, pentru a asigura disiparea caldurii si durata de viata optima. Conexiunile se realizeaza prin lipire sau cleme pe cele patru pad-uri marcate cu polaritate, verificand inainte tensiunea sursei de alimentare.
Intrebari frecvente
Ce driver am nevoie pentru acest LED COB 3W?
Ai nevoie de un driver LED care sa furnizeze 9V DC la 300mA. Un driver cu curent constant de 300mA compatibil cu puterea de 3W este alegerea corecta pentru functionare stabila si durata de viata lunga.
Este necesar radiatorul sau pot monta chip-ul direct?
Radiatorul este obligatoriu — LED-ul de mare putere genereaza caldura semnificativa in functionare. Fara radiator si pasta termoconductoare, chipul se supraincalzeste si se deterioreaza rapid.
Pot folosi acest LED COB in exterior sau in spatii umede?
Nu. Chip-ul nu are protectie la umiditate si nu este recomandat pentru montaj direct in medii umede sau expuse 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.
