Don’t Knock the LED Candle Over

Definitely a silly idea

Seriously, you are dead on that it is quite silly to program something like this into an LED candle! One of points of having electronic or mechanical things to replace real things (ie, a light replacing a candle) is to overcome the limitations of the things they are replacing. A real candle, as you point out, can be a danger or nuisance if tipped. An LED candle not so much.

Maybe restaurant owner wished his/her customers to have the experience of real candle. So opted for LED candle exactly mapping real candle.

You know, I thought about that AandY, and thought that maybe they didn't want someone to realize it was LED and not an actual candle (somehow--not sure if that would be possible?). But putting an alarm on it would completely blow that concept, wouldn't it?? There goes the experience of a real candle right out the window! :)

maybe and this is a HUGE maybe. If the guts of the led candle are also supposed to support a configuration of a seebeck type heat source and led circuit, then tip sense is important. Huge maybe. Gynormous maybe. Tellerex makes these. Otherwise the tip detector is simply a nuisance and a battery depletion device. Also, it doesn't emulate a real candle unless you liken a blinking red indicator and a beep to burning your dining table up.

Could it be their way of forcing users to keep the LED candle oriented properly, just for appearances? I can't imagine why else they would do this.

How crazy. This reminds me of an office chair I bought years ago, when buying something made in China was fairly new. The chair was an excellent copy of an American-made office chair, and it even copied exactly the LOOK of the adjustment levers for adjusting height and tilt. But the levers themselves were incomplete and entirely non-functional, so it was impossible to adjust the chair.

I once saw a very funny advertisement that was based upon a letter from a clothing merchandiser to a factory in Taiwan.  The merchandiser had numerous complaints one of 

which was that the sample jacket has a small cigarette burn on the sleeve from

an accident by the photographer while prepping some advertising shots. The factory had

dutifully burned holes in the sleeves of 10,000 units.

I think they kept the light for just a fun or to make some mimic with the customers.

Yes, you are so right they generally don't understand what they are copying, so will faithfully reproduce every nuance. In the case of the jacket, you need to look no further than people being silly enough to buy pre-worn-out jeans with holes etc. why wouldn't a cigarette burn make sense under those circumstances?

A better candle flicker
mtripoli3   6/20/2013 10:10:09 AM
Years ago, actually before the first of these "candles" rolled out, I was working on an "artificial candle" for a project. The company had used a few different consultants and they weren't satisfied with the "candles" they had seen. Mine, they said, looked so "real" it was eery. They wanted to know what kind of "algorithm" I had used to produce the flickering of the flame. I told them, buy my design and you'll know. They did and I fessed up; I had used some "old" sound chips from another project as the source for flame flicker. Simply attached the led (a yellow one) to the output of the sound chip. These chips use PWM and worked perfectly. If someone had put a speaker on the "flame" they would have heard some version of "Happy Birthday" IIRC. When the device went into production we bought up all kinds of old and overstock sound chips to use as drivers, for 10th's of a cent each.

mtripoli3 you are an absolute genius.  That's a brilliant idea and the perfect way to repurpose cheap technology.

Hahaha, that reminds me of a story I read years ago about the specification of leather preparation for the military required llama dung.  The requirement was there for so long no one remembered why.  They finally concluded it was used to odor treat the fresh leather used in saddles to keep the horses calm.

Haha definetly a not so bright idea, sometimes you just see these type of products and think that what were they thinking? you just have to see what is needed from the product, instead of taking it too far and wasting the resources on it.

It's maddening sometimes, isn't it, when there are such idiotic design features of a product (or lack of, in the case of your chair, Ann!). Now that I write more about design I start to look at products in a different way and start to see where things could have been done differently. I can't think of any examples of any silly design features at the moment, but can anyone else? Maybe it will jog my memory.

Anti-Theft?

As odd as it sounds, tekochip, your explanation is probably the most logical one I've heard.

I seriously have to agree with you, that would make perfect sense.

Another would be product differentiation. I come across 100's of designs that have some stupid feature in a misguided attempt to stand out.

Another explanation is someone wanted to to see how long he could keep a bunch of people musing over the waste of time or otherwise of that feature?

We could go on forever.

Maybe someone will decide that so much brain strain is bad for our health and emulate the 50 page manual I once got (in CD form) for an MS mouse that explained the hazzards of RSI (Repetitive Strain Injury) when using a mouse for extended periods. The driver was some 100k and the manual was in the order of 3MB


I'm still betting on your suggestion.

It is, indeed, an anti-theft feature called Smart Guard (hey, I had to look it up).

http://www.budgetlighting.com/gfx/sc/pdf2010/SC_2010_2_Evolution_Professional_LED_Rechargeable_Candle_Systems.pdf

 

You get a five second warning before the beeping starts and you either have to return the candle to its charger to make it stop or use a key fob.

So it's called Smart Guard. Nice detective work, tekochip. As I always say, we've got a smart audience. I knew someone would figure this out.

You would think that would be an option built-in to something more destructive like a clothing iron. Maybe they could use the candles like those reservation LED disks many other restaurants use.

Perhaps it's used as an alarm to thwart theft.

I can tell y'all WHY this was incorporated.  The programmer read in the data sheet for the controller that there were EXACTLY so many electrons available, and since he/she knew that this limit was nowhere being neared w/ all the features already programmed, they set about to add this "tilt" feature also.  And, that's how it happened.......

What about, shake the light for service???
York123   6/20/2013 10:14:25 AM

Maybe it was intended to get the attention of the serving staff. A button might be too hard to find or see. So they simplifed the activation. Why beeping and a flashing light. We can't base it on our culture. It might be perfectly acceptable elsewhere. It changes the whole perspective, the designer is a genius...

Where on/off ?

You said you didn't find the on/off switch. That would suggest that there isn't one.

My guess is that the light is turned off simply by orienting it 90 degrees, and turned on by placing it upright.  (easy enough with a rolling ball switch). midway between the two, there might be enough resistance to go into "low battery mode", which is normally the problem when such devices beep and flash to attract attention.

It is a lot of fun to play with sensors and design circuits. I think someone was just having fun and used it as an opportunity to play. If I could have gotten paid to design something like that and was given the budget to do so, I would have had fun with the bells and whistles too!

nifty use of sensor

Any of the smaller electronic candles I have seen required you to blow on it like you would a real candle to turn it off and 90 degree or better rotation to turn the light on.  The larger candles seem to have a switch on the bottom side.  Nifty idea I guess.  Makes for candle fun without the fire danger.

My guess is that the "tip switch" was actually intended to sound the alarm if a customer pocketed the thing, which does happen, I am sure.

I agree, John. It makes for candle fun without the fire hazard. When used with a checkered tablecloth, though, it doesn't have the same ambience.
