Fluorescent lamp mods. (starterless)

[carlsfootprints]

hehe

actually, di ko rin alam.. makapagresearch nga..

hmm.. may nagsabi kasi sa akin mas ok na may preheating ung filament para mas mababang voltage nalang ang gamitin para makapagrelease ng arc..

kapag instant start kasi, mas mataas na voltage ang kailangan para mapasabog ung mga electrons sa loob..

-----------------------------

+1 kay sir efren for sharing.. though di ko pa rin maintindihan how it works.. hehe..

[iyo karpo]

hmm opinion ko lang ha.
yung shockings when preheating nakakapagpababa buhay nung lamp, and also its the voltage good to make it comfy sparks and heat up pretty good (600V + DC).

it would be the same as cfl's. cfl's dont need pre-heating.

AFAIK: pre-heating is only needed because the supplied frequency and voltage is not enough to make good arcs so it needs to be forced to make initial arcs.

CORRECT ME IF WRONG PLEASE

ung pre-heating applicable lang yan lamps na connected sa occupancy sensors.

ung instant start, walang pre-heating...d pede ma connect sa occupancy sensor...kung i-connect mo, shorter ang life ng lamps dahils sa frequent on-off operations ng sensor.

ginawa ko po to!ang line e 220v pero di umilaw flickering lang,mahina na kaya yung ballast ko o bulb?,ginawa ko nilagay ko uli starter ko gumana na na ngayon pero may starter  pag ayaw umilaw ng automatic
bakit kaya explanation naman po sa nakakalam? 220 vac ang sukat ng line pag ayaw umilaw?
p.s.: change the capacitor 272,and 222 mylar capacitors/1200v

[efren]

mali ikinabit mo na caps, dapat .22=224 ang ginamit mo 272=.0027 & 222=.0022 lets review the schematic:
 ayan malinaw po, .22 hinde .0027 or .0022

again, .22 is the same as 224
for 40W fl tube use .47 same as 474

[efren]

pagnapalitan mo na yang mga caps at tama ang diodes iilaw na yan, remember 400V o 600V ang mga caps para di pumutok

[odhie]

salamat po sir sa correction yun nalang pala kulang ahihihihi! hanap pako wala kasi mapag kahuyan galing sa sirang fireflly e salamat po hanap ako test ko uli,pero for now nawala na yung napakatagal na pag ilaw ng flourecent ko salamat sir test ko uli pag nakahanap ako ng kukuhaan? yung volts kailangan po ba talaga na 600 to 400v kasi 1200v yung caps na mali ko nilagay

thanks for sharing master efren
another +1 ka sa akin.

sis the higher the better, wag ka lang bumaba sa 350V, 400-600V nasa safe area ka na, 1.2kV is fine but not necessary, we are dealing here with lethal & fire hazard high voltages so safety must come into mind first, always insulate dangerous points, spikes can climb as high as 600VDC

salamat sir

[Ikasamoko]

panu if let say 10 or 15 watts? ballast lang palitan??

[efren]

yes sir, ballast lang, caps 0.22 parin, i once tried using 20W ballast for 10W lamp wala naman naging problema medyo elevated lang ng konti ang lamp temperature...

[Ikasamoko]

pwede kaya 20 watts ballast at dalawang 10 watts na tube?

[efren]

di ko pa na-try...pwede naman pag experimentuhan, malamang kung umilaw man reduced light output

[ericarm]

Maraming salamat po kuya "efren" nagawa ko po ngayon 20W ang inasemble ko nilagyan ko pa ng petsa ng paggawa para malaman ko ang life-span ng FL.

+5 po para sa inyo very useful po nito...yong iba try nyo na din basta sundin lang ang diagram at mga value gagana talaga...

[carlsfootprints]

Maraming salamat po kuya "efren" nagawa ko po ngayon 20W ang inasemble ko nilagyan ko pa ng petsa ng paggawa para malaman ko ang life-span ng FL.

ung life-span ng FL mo will depend on how frequent ung on-off cycles na gagawin mo.. instant start produces larger voltage ignition compared sa merong preheat.. you can check using a scope to verify

[ricdelros]

Why not make it battery operated for brownout..tagulan ngayon...

nabuhay pala ito, congrats, salamat at sinubukan mo gawin.

tatagal yan under normal use & operating conditions, much better kung brand new Fl tube ginamit mo.

definitely, start up voltage spikes can reach as high as 600Vdc.

imho, di lahat pwedeng paggamitan ng circuit na to since it degrades the life of the FL kung madalas ang on-off cycles.. i dont recommend na gamitin ito sa cr at kusina since madalas ang patay-sindi ng mga ilaw rito

ung savings, mas mararamdaman kung madaming FL ang gamit or kung tatagal ang buhay ng lamp..

not all lamps are adaptive to instant start. on my experience sa instant start-up ng bi-pin FL. osram ang pinakamganda. ge naman ang worst.

[efren]

frequent on-off cycles is not recommended in this circuit or the pre-heat types either. Both will end up in a short lifespan of FL. As mentioned earlier "under normal use & operating conditions" I never tried it in frequent on & off duty. I will try using it in the bathroom just for the sake experimentation if it really does result in a shorter life span.

I also encourage anyone interested to build this, BOM won't hurt even the tip of you index finger Oftentimes what is in the paper is quite a bit different in reality. The proof of the pudding is in the eating

you keep on stating that instant start will not degrade the lifespan of FL as compared to pre-heat.. have you tried experimenting? in an actual set-up? i am sorry sir, but i think your assumption is wrong..

now, try to test it.. use that in your bathroom! since that's how you proposed to do the verification
