mewa ganna tiyenne koheda machan???




yeah!!! definitely we should encourage our guys(i personally build stuff for myself,it's a different story)
i can remember years back we built inverters for florescent lamps for our own usethe future is LED lighting bro

nice to hear bro!!!! keep it up....


ganan kohomada





how cool is that ha 




yeah ban i too don't like capacitor way,it even don't have isolation too ne,
the 30W led i got came with 18V 2A PSU,which had a small t/f,couldn't find cheap small t/f to build some,there are 1W LEDs on SL for around Rs90 or so
me number eka weda karanne nha. man den call kala. me wade me kiyana widiyatama wenawanam mata puluwan meka bedahereema karanna CP and WP wala. eth 4n ekata answer karanne nha. puluwannam mawa contact karanna 0718 683 384




machan cmb wala ganna thanak thiyenawada??
These capacitor method sucks. sometimes it kill whole lot of LEDS instantly.
Machan I searched lot of sites to find circuit for driving 1W LED from 230V (switchmode) there are easy to build circuit (no isolation, but have only one inductor) but can't find driving ICs. some circuits have no any IC but they have isolated ferrite t/f.

ah SMPS thama ela bn,more efficient anika.what is the inductor value machn? you can buy inductors from laser electronics,wikarama plaza,1st cross street,pettah.i got some for my projects.1/2W ones,or else ebay is the option.what about 2nd method bro?any details on ferrite t/f,if you have any cct plz send me da link![]()

හරියටම දන්නෑ මචන්. ඒත් ඔය LED හදලා තියෙන්නේ විසිතුරු වැඩ වලට මිසක් ආලෝකය ලබා ගන්න නෙමෙයිනේ. ඕවා හදන කම්පැනි වලින් ප්රමිතිය පන්නලා යම් යම් රසායනික විමෝචනය කරනවලුsudu pata hinda shape ati ny![]()
The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDs—extremely bright LEDs that also have a tightly focused viewing angle of 8° or less—could, in theory, cause temporary blindness, and so are classified as "Class 2".[82] In general, laser safety regulations—and the "Class 1", "Class 2", etc. system—also apply to LEDs.[83]
While LEDs have the advantage over fluorescent lamps that they do not contain mercury, they may contain other hazardous metals such as lead and arsenic. A study published in 2011 states: "According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb [lead] at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), Pb (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous.".[84]

machn swichmode type is the best, but bro if you are doing a prodution u should search for alternatives to reduse the cost of the product..this capacitor type power supply which I developed didnot damged till now I'm using this for dimmers(can not be dimmed)..that is why i can give 1 yr warranty...These capacitor method sucks. sometimes it kill whole lot of LEDS instantly.

මිල දාපන් මචන්. අනිත් ඒක ආලෝක තත්වය කොහොමද? නිකන් ලකේ පුයිට් වගේ නම් වැඩක් නෑ බං![]()
