Chip LED verde 3W pe radiator aluminiu star
Chip-ul LED SMD 3W cu lumina verde montat pe suport radiator de aluminiu in format star este solutia compacta pentru proiecte DIY, inlocuiri de surse luminoase sau constructia de corpuri de iluminat personalizate. Suportul metalic disipa eficient caldura generata, prelungind durata de viata a diodei. Marcajele de polaritate vizibile pe placa faciliteaza conectarea rapida si corecta la sursa de alimentare.
Ce obtii cu acest produs
- Lumina verde intensa si uniforma — potrivita pentru semnalizare, decoratiuni tehnice sau experimente electronice
- Radiatorul de aluminiu integrat previne supraincalzirea si asigura o functionare stabila pe termen lung
- Polaritate marcata direct pe placa — conexiunile + si - sunt clar identificate, fara risc de montaj gresit
- Format star compact de 20mm — se integreaza usor in spatii reduse si in proiecte cu mai multe chip-uri conectate in serie
- Chip-urile pot fi conectate in lant direct din fabrica — imagini cu siruri de module confirma compatibilitatea pentru configuratii multiple
- Consum redus de 3W la flux luminos ridicat — eficienta superioara fata de sursele conventionale de aceeasi putere
Cum functioneaza si cum se instaleaza
Chip-ul LED este lipit direct pe placa de aluminiu tip star, care preia si disipeaza caldura fara a necesita radiator extern suplimentar in aplicatii de putere redusa. Conectarea se realizeaza prin lipire sau prindere cu surub pe pad-urile marcate cu + si -, la o sursa de alimentare stabila de 3,2V-3,6V cu driver sau rezistenta de limitare a curentului. Pentru aplicatii cu mai multe module, chip-urile se pot conecta in serie sau in paralel folosind pad-urile laterale ale placutei star.
Intrebari frecvente
Am nevoie de driver separat pentru acest LED de 3W?
Da, chip-ul necesita o sursa de curent constant sau un driver LED care sa furnizeze 500-700mA la tensiunea de 3,2V-3,6V; conectarea directa la o baterie fara limitare de curent poate deteriora dioda.
Este suficient radiatorul de aluminiu inclus sau trebuie racire suplimentara?
Pentru functionare continua la putere nominala de 3W se recomanda aplicarea unei paste termice si montarea placutei star pe un radiator extern sau pe o suprafata metalica; la utilizare intermitenta sau in aer liber, suportul inclus poate fi suficient.
Pot conecta mai multe astfel de chip-uri impreuna?
Da, placutele star sunt proiectate pentru interconectare in serie sau paralel prin pad-urile laterale, asa cum se observa in configuratiile cu mai multe module prezentate; asigurati-va ca driver-ul ales suporta tensiunea si curentul total al configuratiei.

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.
