where do we find it?
Thanks

Clearly you don’t understand the power supply incompatibilities between a fluorescent light fixture and an LED light fixture. Fluorescent lights operate with a significantly higher voltage than LED lights, also the starting mechanism in the fluorescent light ballast would likely destroy the LEDs as it spikes the voltage to approximately 1000 volts in order to light the bulb.

@Noisysplatter: Don’t talk unless you have a suggestion on how to fix it.
Pretty brilliant! Keep up the good work!

@Jimmy C

What’s wrong with noisysplatter’s remark? Yours is more bizzare;

“Don’t talk unless you have a suggestion on how to fix it”

Here is a suggestion on how to fix it: Don’t pursue this concept any further without research in to fluorescent lighting fixtures

Agreed. This is a pretty poorly executed idea.

Dude, do you even know how fluorescent lights work?

Did you know that you can get the current converted? With a quick search I can find a mini converter with dimensions of 5cm x 2,7cm x 2,1cm. Its smallish.. and it could give only power to one 3 W power led. Size of another converter size of 14 cm x 4,5 cm x 2,8 cm could power up seven 3 W leds.

With innovative design, creativity and a bit money you could get a customized converter to this tube light with maybe few sacrifices in design?

…or maybe the converter could be plugged in the starter of the fluorescent light.

Beautiful concept and completely plausible in my thinking.. luxury at the moment if done.

I don’t want to sound like a naysayer but here are a few comments:

1) Seems like the bellows design will introduce undesirable lighting artifacts, especially if the tube is not fully-extended or fully-compressed. What will the lighting/shadow pattern look like if the 120cm lamp is stretched out to only, say, 90cm? Will one end of the lamp be dimmer than the other?

2) Heat dissipation will be a problem. A flexible bellows material will likely be a poor heat conductor. This design will need to either under-drive the LEDs (requiring many more LEDs to produce adequate light) or some way to extract heat otherwise the LED lifespan will be short.

3) LED retrofit tubes for existing fluorescent light fixtures already exist. One feature common among them is a much lower lumens output than the fluorescent tube they’re designed to replace. For example, a 32-watt T8 2700Kelvin lamp typically produces around 2800-3400 lumens. The LED retrofits currently on the market typically produce about half that. I suspect the bellows design will emit even less light due to the bellows material itself and heat limitations.

This is a cool concept. Is it possible to remove the transformer and starter circuit from a fluorescent socket and connect it directly to 120 VAC? That way, you could connect 120 V worth of LEDs in series with a resistor and a full-wave rectifier, and you would have dispensed with the starter circuit altogether.
Also, for future reference, hydragyrum (Hg) is called “mercury” in English.

Nice idea!It is kind of a reverlutional ‘fluorescent light’.

There are already fixed-length LED replacements for fluorescent lights. They are not plug-and-play, you have to disconnect the FL ballast. Rectifiers and step-down transformers are already built into the tube.

“Stretchy” lights are a neat idea.

I’m so sorry to say that this is a concept with poor/no research……If you want your work become a real product instead of remaining forever, please work harder on background research, lighting design is not as simple as you think.

Yes, actually. I agree with told all above. We are able to communicate on this theme.

Hi Everyone, i’m D’light main designer.
First of all, thank you for your opinion.
But the d’light is just concept design.
Mainly look at the idea and gave a nice.
Thanks.

The information and the detail were just perfect. I think that your perspective is deep

Heya! I’m at work surfing around your blog from my new iphone! Just wanted to say I love reading your blog and look forward to all your posts! Carry on the great work!
