Chip LED COB RGB 3W pentru iluminat multicolor
Chip-ul LED COB RGB 3W cu diametru de 28mm este o sursa de lumina compacta, capabila sa produca rosu, verde si albastru independent, permitand crearea unui spectru larg de culori prin combinarea canalelor. Este destinat proiectelor DIY, iluminatului decorativ si aplicatiilor de scena unde controlul culorii este esential. Formatul COB cu baza de aluminiu asigura o disipare termica buna chiar la dimensiuni reduse.
Ce obtii cu acest produs
- Trei culori independente intr-un singur chip — rosu, verde si albastru controlate separat pentru mixare libera a culorilor
- Format COB compact de 28mm — se integreaza usor in corpuri de iluminat personalizate, spoturi sau proiecte electronice
- Baza metalica tip stea pentru fixare sigura si transfer termic eficient catre radiatorul de racire
- Consum redus de 3W cu emisie luminoasa vizibila si intensa pe fiecare canal de culoare
- Compatibil cu drivere si controlere RGB standard — nu necesita componente speciale greu de gasit
- Constructie robusta cu invelis siliconic protector al chip-urilor — rezistenta buna la manipulare si vibratii
Cum functioneaza si cum se instaleaza
Chip-ul LED COB RGB 3W dispune de trei anoizi separati pentru rosu, verde si albastru si un catod comun, conectarea realizandu-se prin lipire sau cleme pe padurile marcate de pe baza metalica. Pentru functionare corecta este necesara o sursa de alimentare cu tensiune constanta adecvata fiecarui canal si un radiator de racire aplicat pe spatele bazei de aluminiu, fixat cu pasta termoconductoare. Nu este recomandata functionarea prelungita fara radiator, deoarece temperatura excesiva poate deteriora chip-ul.
Intrebari frecvente
Ce tensiune de alimentare necesita fiecare canal al acestui chip RGB?
Canalul rosu functioneaza in general la tensiuni directe de 2,0–2,4V, iar canalele verde si albastru la 3,0–3,4V; curentul recomandat per canal este de aproximativ 350mA pentru puterea nominala de 1W pe canal.
Am nevoie de radiator pentru acest LED COB de 3W?
Da, utilizarea unui radiator cu pasta termoconductoare este obligatorie pentru functionare stabila si durata de viata indelungata; fara racire adecvata, temperatura junctiunii creste rapid si chip-ul se poate degrada.
Pot obtine lumina alba cu acest chip LED RGB?
Se poate obtine o aproximare a luminii albe prin activarea simultana a celor trei canale la intensitate egala, insa rezultatul nu va fi identic cu un LED alb dedicat datorita diferentelor de eficienta intre canale.

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.
