Won't a thin region of a lamp filament have a higher temperature than
the rest of it all the time, not just when the lamp is turning on?

It will, but due to the thermal coefficient of resistance of tungsten
(most other metals are similar) the heating will be even greater when the
filament heats from cold. The hot spot gains resistance faster, so it
drops a greater voltage while the rest of the filament is still cold.


disclaimer: figures made up to illustrate the point

assume a constant-voltage supply compute the power disipated by he
thin spot (middle resistor) in each case


cold ----[100]---[1]---[100]---

hot ----[1000]-[12]-[1000]----

during warm-up thin spot warms up fastest.

start ---[200]---[3]---[200]---



yeah, it would be a good project for the mythbusters, I'd love to see
a slow motion film of an incandescent lamp failing at turn-on.
but could they affor do dedicate their fast camera for long enough.

The Americans do seem generally to be used to sending a lot by courier
when we would just put in the post. Tending to happen in the UK also
even though the Royal Mail / Parcelforce often give a better service and
of course do not charge extra to send further. There has been a big
campaign in the North of Scotland about companies charging extra for
many postcode areas.

Digi-Key sent me (in NZ) a postcard by royal mail (from UK) the other day.
if it's still in the waste bassket on monday it'll check to see if it's a
preferred spelling thing (eg: "catalog" vs "catalogue") or perhaps it was
just cheaper to do it that way.

Several years ago the USPS restructured their rates for mail outside of the

They did a survey of prices of the courier services, and simply charge 1/2
of what the courier services do. If you want registered mail, they charge
another $12 or so for it.

Compare that to China which charges a few dollars to send a package, and
another dollar or so for registered mail. Or the UK (and the rest of the
EU) that charge about $5 for postage and registered mail.

Chinas international mail is heavily subsided. <hearsay> I've heard that
it's so heavilty subsidised that in some cases they pay the sender

exporters (and therefore the balance of payments) I can't see the
republican party getting behind subsidising a "state run monopoly".

Sorry to hijack this thread but I have an actual electronics repair

Isn't the USPS already a state run monopoly which is subsidised?

Due to the apparently lack of data and my curiosity, I was thinking of
throwing together a crude experiment.  Two lamp bases, two 40 watt
clear envelope incandescent lamps, two SSS (solid state switches), and
some kind of pulse generator.  30 seconds on should be enough to get
the filament hot enough for sublimation.  30 seconds off should be
enough for it to cool down for a cold start (I need to check this with
an IR thermometer).

However, I have no intention of running this test for 1000+ hours.
Instead, an accelerated life test can be done with higher than normal
voltages.
<http://www.welchallyn.com/documents/Lighting/OEM_Halogen_Lighting/MC3...>
For halogen bulbs, they use:
  Life = (Vdesign / Vapplied)^12.0 * Life at design voltage
For a 1000 hr lamp running at 120% of the rated voltage, the life
might be:
  life = (1/1.2)^12 * 1000 = 112 hrs
which is more reasonable for my tinkering and for Mythbusters.  With
power cycling, the life will be even less.  I should have a Variac
somewhere in my junk pile.

Hi SEB. Well I sent an email to Don klipstein on this topic. And
have permission to copy his reply.

<from Don K. below>

My apologies - I have been off Usenet for a little over a year.
Hi Don, I was wondering (out loud) if you still lurk on the
sci.electronics.basic usernet forum?
(So I figured I'd just drop you an email.)

We have a question about the aging of incandescent bulbs from being
turned on and off. You seem like quite a lamp expert and I was
wondering if you've ever come across any real data on the subject.

As for real data on effect of switching causing wear on
incandescents:

I know some data.

1: It is true that incandescents often failon cold starts. However,
I
know a mechanism where an aging incandescent becomes unable to
survive
a cold start a little before it becomes unable to survive continuous
operation.

I explain this in: http://donklipstein.com/bulb1.html#how
And: http://donklipstein.com/bulb1.html#wbt

2: In incandescent traffic signals, the bulbs for yellow last longer
than
for red and green. So even after being switched on and off about a
million times, on-time is still a significant factor in life
expectancy.

However, traffic signal bulbs have a more vibration-resistant
filament
than standard incandescents.

3: Flashing and chasing marquee lights used to be incandescent until
cold cathode CFLs became economically available. Cold cathode CFLs
are special CFLs that are dimmable and blinkable, and flashing them
does not detract from their life. However, their efficiency is less
than that of hot cathode CFLs. Some marquees still use
incandescents.

4: I did an experiment to check for voltage drop in one of those
now-hard-to-get thermistor-type life-extending "buttons" to attach
to the tip of the base of an incandescent. The device claimed to
double the life of the bulb. I found enough voltage drop to account
for 50-60% life extension. Light output was reduced 13%, and power
consumption of the combo of the bulb and the thermistor was only
2.05%
less than that of a bulb connected directly to the line.

5: In my experience, incandescent holiday lights that blink last
longer
than those that don't. However, most of my experience is with low
voltage bulbs whose short filaments are probably sturdier.

6: Some incandescents make an audible "ping" when switched on.
However,
deflection of the filament does not necessarily strain the filament
past its "endurance limit" - the threshold of causing metal fatigue.

7: Some railroad crossing signals have a set-up where bulbs have a
resistor added in series with them for the first half second or so
that they are on. However, this may be done because of how serious
the problem is widely said to be, and how serious it actually is
appears
to me to be much less.

8: One of my friends had a bathroom fixture with a high wattage bulb
that
was constantly run dimmed by a dimmer. He experienced little gain
in
life extension. Since his bulbs significantly audibly buzzed, I
suspect
his filaments resonated at the power line frequency or one of the
power
line frequency's lower harmonics.

9: My mother had some incandescent nightlights that had diodes in
them
to significantly dim the bulbs - which should have made the bulbs
last
for decades. However, they did not.
One thing I noticed: These 4-watt bulbs had extremely thin
filaments,
and with a diode and therefore being off half the time 60 times a
second, their temperature varied greatly up and down 60 times a
second.
I could see that from rolling my eyes up-and-down while looking at
them.
Maybe the filaments at times resonated at the power line frequency
or
a lower harmonic thereof. That could easily produce sound too weak
to
hear from more than a couple inches away, because such low wattage
120V
incandescents have a vacuum rather than a gas fill.

Or, maybe those bulbs do not do well with DC due to high voltage,
vacuum, and the ends of the filament being close to each other.
Please see: http://donklipstein.com/bulb1.html#dc

======================

Overall, I am seeing generally that cold starts are not nearly as
bad as many say they are, but in a few bulbs they can be. The data
appears to me to be majority in favor of "little to generally no
problem from cold starts", but it is incomplete.

I would also suggest reading:

http://donklipstein.com/ltrouble.html#i

====================

Hope this helps!

Have you taken it apart yet? Try cleaning the lens. In a dirty,
smoky or wet environment the lenses can become coated with stuff.
I had it "working" a little after all that and an adjustment to the
potentiometer on the back of the lazer as instructed. However it would
only read one specific CD and scratched some CD's when it went thru its
ejection cycle (disks would not spin down before ejection!) so I removed
the tray and wont use it anymore. Further research indicated AIWA was
part of a class action lawsuit in the 90's due to their CD players being
crap. They're out of business now anyway. Good riddance.

Aiwa is still around as I understand it. They're owned by Sony.
The biggest problem with their 3-cd models was that so much dust would get
into the lasers that even cleaning eventually would not be enough and the
laser would need to be replaced.
By the way, the lasers were made by Sony, the same pickups used by many
manufacturers at the time.

Worked on many of them, the customers were mostly satisfied.

Later models had sliding covers that covered up the laser lens when not
playing. This helped but of course was not a perfect solution.

That means for my proposed test comparing a 50% duty cycle flashing
light bulb, with one that is on continuously, the continuous light
bulb will burn out first.  That's the opposite of what I saw with the
theater marquee bulbs.  Now, I'm really tempted to run the experiment.

Experiments can be very useful.
I'd worry most about how you turn on the bulbs.
Maybe just some simple relays?

1,000 hours isn't all that long. (or are you going to over-voltage
the bulbs?)
I guess I'd want at least 10 bulbs in each group. Say 60 watts.....
1200 kW-hrs.

That's looking like more money than I'd want to spend on the
electricity.

I haven't seen any new kit from them in any stores for years. Sony
bought them out and killed it off:

"Since 2004, however, Sony seemingly began rolling back its support for
the Aiwa brand, and by 2005 Aiwa products remained on sale in only
selected territories around the globe. In 2006, Aiwa products were
discontinued and no longer sold in the market.

As of September 2011, the Aiwa website still existed to provide
customer-support telephone numbers for some territories and regions, but
it also contained many broken links and blank pages. In other regions,
such as Europe, it redirected to a page on the Sony website stating that
the Aiwa website had closed. The last apparent update to the website was
in June 2008.[1]"

Wanna buy a used laser? Heh...its a 1997.

Mark Z.

We have another one, made in 2001, the tape decks on that one dont work.
So, to recap: we have two units from failed electronics maker AIWA, and
both have non-working components. My conclusion: AIWA was rightly killed
off by Sony since its quality sucked balls.

Oh, but we also have a SHARP single CD unit from 1991, it works *perfectly*.

The tape decks have belt problems, like every other brand. The Aiwa's were a
very cost-effective item at their price point.
I have no desire to defend Aiwa - I find many of their products difficult to
service. But it sounds to me like perhaps the problem here may be as much
the technician as the product.

rightly killed off by Sony since its quality sucked balls.

Oh, but we also have a SHARP single CD unit from 1991, it works
*perfectly*.

The tape decks have belt problems, like every other brand. The Aiwa's
were a very cost-effective item at their price point.

Translation: you get what you pay for.
I have no desire to defend Aiwa - I find many of their products
difficult to service. But it sounds to me like perhaps the problem here
may be as much the technician as the product.

Oh snap! But I'm not a technician. No training whatsoever.

FYI I recently copied a bunch of songs up to a micro SDHC card and I can
still use bluetooth A2DP to play those songs through the speakers connected
to a laptop with bluetooth. So that means even though the WiFi quit working
on the device mentioned above the bluetooth still seems to work OK so they
must not be using the same transmitter or same receiver.

They don't. The antennas are separate, even.
