am tot cautat prin comert, si nu am gasit. as prefera una construita, am primit si o schita de la Luminus Devices, am postat mai sus, dar nu stiu cine poate sa mi-o construiasca. eu nu am nici un fel de cunostiinte in domeniu, si pare greu de invatat :)

eu din cate am inteles: pentru a scoate valoarea maxima de lumeni, trebuie sa il alimentez cat mai aproape de 21 A. intenzionez sa pun LED ul intr-o sursa de lumina, deci am sa-l pot raci cum trebuie. Am nevoie de toti lumenii.

De la mine.



Round emitting aperture provides most efficient match to circular optical systems and narrow

beam projectors

Variable drive current: 1A to 28A for CBT-140 white

High CRI at tungsten and daylight color temperatures for natural lighting

Environmentally friendly: RoHS compliant

Extremely high optical output from a 14mm² circular source: Up to 3,700 white lumens

Unencapsulated package preserves small etendue facilitating narrow beam optical system design

Chip-on-board package assures straightforward system assembly with the best possible thermal performance for high power devices

Integrated thermistor enables consistent temperature monitoring during operation for high

system reliability

High thermal conductivity package - junction to heat sink thermal resistance less than 0.6ºC/W


Am intrebat daca e corect... :rade:

Cred ca cel mai bine e sa spuna tipul exact.
