A new twist on flame lamp construction.

This is an interesting direction for the flame effect lamps. Same visual effect, but the main circuitry is now all on a single flexible PCB that literally gets rolled up and shoved into the housing.
Loads of possibilities for re-purposing, although finding this style may be tricky as the image of a lamp on a listing may not match what you get.

You can get ripple projectors that look like a flaming effect when used with red/yellow LEDs. It would also be an interesting application for a mini LED video projector and a video of a real flame.

2018-02-25 18:36:45 +0000 UTCReading Pbrin's comment above got me wondering about the possibility of creating a cheap "flame-effect projector" that you could throw onto any surface, built from one or more of these flexible PCBs + a scavenged lens assembly from a cheap projector or moving-head light, mounted into a suitable housing. Obviously the projection distance and brightness would be severely limited by the low lux output from the LEDs, so any "serious" application would still require the traditional approach of a projector lamp/lens + gobo and gels, but it could be a cool solution for small-scale SFX like the abovementioned fake fireplace, where you could perhaps mount the projector below (or recessed into) the mantlepiece.

2018-02-23 23:48:07 +0000 UTCIf you flattened out and fixed about four of these in line to a base board it might make a pretty decent fake fireplace effect (behind suitable fake logs etc). The flame effect in the bulb is remarkable. Great item. Thanks Big Clive
2018-02-23 20:45:03 +0000 UTCSo, as for the PNP tranny's, the only thing I can come up with is that they wanted to use a 12V supply and they wanted MAX BRIGHTNESS for each PWM pulse, to allow for a smoother dimming effect? (I'm sure you know this already, but the reason why PNP would be preferred over NPN for this, is due to the lower Vce(sat) voltage drop. And the reason why they are placed switching to the bottom rail, is because they didn't want to do level shifting between the microcontroller and the transistors).

2018-02-23 10:51:32 +0000 UTCI have a sudden insane urge to buy several of these, desolder all the leds, and replace them with those self-cycling RGB chips. TRIPPY FLAMES MAAAAAN!!

2018-02-23 09:05:01 +0000 UTCHow do we blend these with solar? THAT would be the proverbial shit

2018-02-23 00:56:17 +0000 UTCI love these things so much that the lamps I build from industrial scrap are starting to be made with them in mind. Something fascinating to me about a vapor-proof fixure with a fame lamp inside. It completely reverses the idea from protecting the bulb to protecting you from the "flame". I recently got a few that need an extra layer of diffusion as the LED dots are too visible as-is, but I also have a supplier of ones I really like. As always, THANK YOU for this insight into the construction of these awesomely cool lamps. Clive, may I post the Instagram link to my lamps?

2018-02-23 00:53:56 +0000 UTCDifferent company I'd guess, but who knows.

2018-02-23 00:43:34 +0000 UTCAre they going to threaten to sue you again over this one?
