Chip LED albastru 3W pe radiator de aluminiu
Chip-ul LED albastru SMD 3W este montat direct pe un suport tip stea din aluminiu, conceput sa disipeze caldura eficient si sa prelungeasca durata de viata a diodei. Este potrivit pentru proiecte DIY de iluminat, panouri LED personalizate, acvarii, iluminat decorativ sau inlocuirea componentelor defecte din corpuri de iluminat existente. Formatul compact si marcajele clare de polaritate faciliteaza integrarea rapida in orice circuit.
Ce obtii cu acest produs
- Lumina albastra intensa cu flux cuprins intre 30 si 40 nm — potrivita pentru aplicatii decorative, acvarii sau efecte vizuale specifice
- Radiatorul de aluminiu tip stea integrat elimina necesitatea unui disipator separat, reducand costurile si complexitatea montajului
- Marcajele de polaritate plus si minus imprimate pe PCB previn conectarea gresita si simplifica cablarea
- Dimensiuni compacte ale chip-ului LED albastru 3W — diametru radiator 20 mm, usor de integrat in spatii reduse
- Disponibil in cantitati multiple, fiecare chip identic dimensional si electric, ideal pentru panouri sau matrice LED
- Consum real de 3W la curent de 500-700 mA — raport eficient intre luminozitate si putere consumata
Cum functioneaza si cum se instaleaza
Chip-ul LED albastru SMD 3W se alimenteaza direct la o sursa de curent constant reglata intre 500 si 700 mA, la o tensiune de 3,2-3,6V. Conectarea se face pe baza marcajelor plus si minus inscriptionate pe radiatorul tip stea, fara componente suplimentare daca folosesti un driver LED adecvat. Pentru o functionare stabila la putere maxima, este recomandata aplicarea unei paste termice intre radiator si suprafata pe care il fixezi, desi radiatorul integrat asigura deja o racire de baza suficienta pentru utilizarea in conditii normale.
Intrebari frecvente
Am nevoie de un driver special pentru acest chip LED de 3W?
Da, este necesara o sursa de curent constant de 500-700 mA la 3,2-3,6V. Nu conecta chip-ul direct la o sursa de tensiune fara limitare de curent, deoarece se poate deteriora rapid.
Trebuie sa montez un radiator suplimentar sau cel de pe PCB este suficient?
Radiatorul de aluminiu integrat asigura racire de baza adecvata pentru utilizare intermitenta sau in spatii cu ventilatie. Pentru functionare continua la curent maxim de 700 mA, se recomanda fixarea pe o suprafata metalica sau aplicarea de pasta termica.
Ce dimensiuni are radiatorul tip stea al chip-ului LED?
Diametrul exterior al radiorului tip stea este de 20 mm, iar dimensiunile chip-ului LED propriu-zis sunt de 7 x 3 mm, conform datelor tehnice ale produsului.

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.
