120v LED bulbs -- innards

Around your neck would be very nice, AlwaysWrong alias jack snipped-for-privacy@cox.net

You got no nuts. Your mad is just your personality, you POS!

You're a goddamned retard, and your mother is a criminal.

I have enough to tell a pussy like you that fact. What you gonna do, pussy boy piece of shit?

Just so I'm clear -- GIANT RAT -- you have some real problems.

I'm outa here and I'll remember to avoid you.

Seriously, you need some help dude.

Funny, I saw your posts as indicating your need for professional assistance. In both electronics as well as psychological.

Because you are also a pussy. Maybe one day you will learn to face your inadequacies.

No. An asshole like you, whom thinks he is better than others, and whom thinks he has the competency and qualifications to assess others needs help.

You are that asshole, asshole.

And you couldn't understand a character like George Leroy Tirebiter if your life depended on it.

Do a google search and learn something, you pathetic punk excuse for "modern maturity".

Just so you (we) are clear, chump. YOU are the mental case.

He's (she's) also on record as being prickless.

I did find several possibly serious flaws in my circuit.

First, I found that most LEDs have an absolute maximum surge current of=20 about 3x to 5x normal, so the usual 5mm LEDs are generally 20-30mA=20 continuous and no more than 100mA peak. My circuit uses a very low duty=20 cycle PWM with current peaks of 300mA or more, so that may damage the = LEDs.

Second, the 100mH inductor was based on an ideal model, and when I added = the=20 ESR of a real inductor (90 ohms for a Murata 19R107C), the efficiency=20 dropped to about 70-80%.

I was able to restore 90% efficiency or better, and reduce the surge=20 current, by using a 1.5H choke with 70 ohms (Triad C-85X) for 86% = efficiency=20 and 90mA peak with 19mA and 1.88W out, but that is a chassis mount choke =

about 1.25" cube and 0.4 lb. Costs about 7 bucks. But according to the = spec=20 sheet it's only rated for 10mA (although I think that should be 100mA).

The slightly larger C-24X 1.0H 50ohm is rated for 240mA and I get 88%=20 efficiency at 26mA and 2.6W, peak current 130mA. About $8, 0.75 lb.

And there is an even larger C-17X 1.5H 40ohm 300mA which gives almost =

90%=20 efficiency at 29mA and 2.94W, peak current 110mA. About $18 and 1.6 lb.

Using it for a string of 33 high power 1W LEDs I can get 235mA and 26.6W =

with little ripple, and 89% efficiency. But that's really the same as = just=20 using the diode bridge and the choke as ballast.

So, as Heinlein asserted, TANSTAAFL, and the realities of the physical = world=20 will get you every time. But this has been a good learning experience, = and I=20 think it should be possible to make an inexpensive and fairly simple=20 controller using much higher frequency. The components are readily=20 available. The difficulty is providing the power to a device that runs = on 5V=20 or 12V or so, from a nominal 175VDC source. For a 10mA device such as = the=20 LT1241, a resistor and zener will dissipate 1.7 Watts. And it's twice = that=20 for a 240VAC application.

And there is the single IC solution=20

which works up to =

450VDC=20 and is only about $2 from Mouser. It uses a 100 mH inductor (for 20mA) = but=20 runs at 100kHz and does not have the large surge currents. For 200mA = LEDs=20 the inductor is only 10mH.

Paul=20

As perhaps a final answer to the question of what may be in such bulbs, = I=20 searched for Supertex on Mouser, and they have a TO-92 or SOT-89 device = with=20 just about everything but the inductors and diodes, useable on nominal =

120=20 or 240V mains, 50mA output, for $0.70/100s:=20

Can't beat that!

Paul=20

YOU aren't paying attention. I have told you time after time that the headers don't contain enough information when you access Giganews through Earthlink. I had very few issues when Earthlink had their own server farm or when they outsourced to Supernews. After Giganews bought the Supernews corporate accounts, I have to filter in my newsreader. There are too many trolls for Newsproxy to handle all of them, due to its limit of 100 filters. I use Newsproxy to flag troll ad political group crossposting, and to flag people who troll a lot of newsgroups. Then a filter in Netscape marks them read so it doesn't fragment trolled threads.

I maintain a list for newbies to the group.

I use Giganews. What I'm trying to point out is that judicious use of "Don't kill" filtering along with "kill" filters cuts the "test patterns" wa-a-a-ay down... like to a few entries.

I stopped using Newsproxy when I switched to Giganews since they provide message-ID in their headers... though I may return to using it as a pre-screen against those that insist of troll-feeding Slowman and Allison... kill messages that contain (Sloman|Slowman|Allison) in the body of the message ;-) ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

I don't get the nessage IDs, without downloading the messages. Giganews offers a different, stripped down service to corporate accounts for ISPs. It isn't what they sell to individuals. They also have private newsgroups I can't access. Those are only availible to individual accounts.

I didn't realize that some ISP's were offering Giganews stripped down. I'm paying $7.99/month... well worth the price for the ability to block whole newsgroup cross-postings, plus Slowman and Allison and Larkin (I threw out an olive branch to him and got it cut off... but he's brainless and useless anyway... oh, well ;-) ...Jim Thompson

I already pay too much to add another $8 a month for newsgroups if I can avoid it. The reduced headers supposedly reduce the load on Giganews server farm, but not if you have to download more information to trap what you don't want. I'm thinking about using an old computer for a local new server, behind a firewall so it won't be visible to others.

You are a total loser.

You wouldn't know what an olive branch was if someone beat you half to death with one.

You wouldn't, for sure.
