UV LED exposure box
« on: May 24, 2009, 03:02:03 PM »
Biglang na-alala ko to nung nabuhay uli yung thread ng diy exposure timer.

Question:

Ano bang klaseng UV LED ang pwede gamitin at ilan LED ang effective for a particular area.  May nakagawa na ba nito?  Anong wavelength at brightness ng UV LED ang gamit ninyo and saan nakakabili asides from ebay sa murang halaga.

Gaano katagal ang exposure time kapag UV LED ang gamit?

ako gamit ko yung uv led 30 seconds lang ang exposure time at kung gusto nyo ng murang uv led baka matulungan ko kayo "ahehehe raket na naman bwahahaha"

^mura na... free shipping pa yung 500 pieces.

magkano ang benta mo nyan nucleus? kasi kung bibili ako, parang sobra naman... naisip ko, ibenta yung iba. yung reasonable naman.

tamang tama yung sirang scanner namin for enclosure.:)

OK na OK yung price nung 500 pcs  ... sulit na sulit pero kung 100 pcs, sa ebay na ako kasi may kasama ng resistor for both 5V and 12V supply, same lang ang price and free shipping.

Anyway thanks, nakahanap ako ng alternative source ng water clear blue LED na mura na gagamitin ko sa LED cube project ko.

^ Sige na nga  ;) .....  Logical AND kasi gamit ko kaya pagkakaintindi ko 200 resistors in total.   "Free to provide 100 pcs resistors for 5V DC and 100 pcs resistors for 12V DC"

Pero dun na rin ako bibili  sa online store na sinabi mo para isang bilihan na lang.  Pogi points nga pala sa yo! ;)

Baka naman may alam ka rin bilihan ng smd leds na mura  ??? ??? ::)

completo na akong materials.
UVLEDS, resistors, transistor for current limiting, power supply at kahit yung plywood meron na din....

nakakatamad naman magconstruct! heheh ;D

Sino ba ang nakagawa na???

strictly, kinunsider nyo ba yung formation ng LEDs? mine is a only 10degrees...  kailangang magkakalapit at medyo malayo.

ahmm yung sakin boss pahalang at patayo lang, yung pagkakalayo-layo naman inacual ko lang yung distance ng dalawang LED tinusok ko sa karton tsaka ko itinapat sa (clips/glass/PCB setup) then pinower ko yung LED hinanap ko yung tamang distansya ng dalawang LED na magiging pantay ang sinag sa layong 1 inch sa setup ::)

ic... salalamt sa tip. di ko naisip yun ah!!! tutal mauuna naman pala yung construction ng board bago yung enclosure.


ilang degrees sayo? gaano kataas ang kinalabasan kung 1" ang distance?

20 degrees yung sakin 1" po angibig kong sabihin ay anglayo ng mismong led panel sa pcb setup 12mm po yung distansya sa isa't isa ng mga LED ko ;)

salamat sa insights.:)
