3000lm LED E-bike light with 80v MAX driver.

[ktronik]

Hey Guys...

been a while...

Made this custom 3000lm LED light for a E-bike customer in the Czech Republic, needs to work up to 80v...I added some dimming 1000lm / 3000lm...and a on / off switch...via some good old otto military spec aircraft switches...they are antiteasble...now thats a good switch. The whole thing is fully waterproof.

As the only 30w LED driver that works at 80v, (taskled hyperbuck) is of analog design, we had to use toggle switches...but its built like a tank and will last 10 cold Czech Republic winters...

enjoy

I don't suppose you could attach the pics to a post in this thread, for those of us that cannot view/access facebook for various reasons?

like this?!?!?

Nice work, any info or circuit diagram?

That looks like a sweet little light setup. i gotta get me one of those.

nice work on that dimming switch!

Thanks quys!

It pretty simple on the inside... 1x taskled hyperboost 3.2A led driver. 3x Cree XML LEDs. As the driver is a analouge type, it's set at 3A to led string, via the scence resistor, switch just parallels that resistor, with another for the 1A dimming mode.

The driver is too big for housing so had to go into the remote box.

Normaly the micro controlled drive is inside the light, and is driven via a MoM switch on unit....

Hope this helps

Doh, I mean taskled hyperbuck driver...

If you could supply less than 25v it's a cleaner look, as only the light is needed....

Looks bullet proof. 8)

Yea I love the work especially the color. How about an action shot.

That looks great, how much to make me one for my 48volt setup

Hey,

will do a action beamshot, soon...

err no more e-bike drivers left, can you tap less that 25v somewhere??

lights are going for $250 at the moment...+$100 for the remote box ect...so get a 3A min switchmode PSU to give 12-15v (from 48v) and we good to go...

cheers

can you do a build thread to show us how you made this light?

 

[grindz145]

That thing is badass. I totally wanna see the source man The driver itself handles 80v? wow.

 

[ktronik]

Yep, High: 2926.8lm, Med: 1770.3lm and Low: 959.7lm.

**Using a b3flex digital 30w LED driver, for dimming**

 

[ktronik]

OK, currently the E-bike drivers are out of stock...

so as a work around we use this...

48v (15-50v) input, output 12v 3A.
http://www.ebay.com.au/itm/Industry...t=AU_Solar&hash=item337c168644#ht_2239wt_1147
Use this DC-DC buck converter to give 12v to 3000lm light.

so now your light looks like this...

Mom Switch on rear, controlling a b3flex inside, fully programable 30w LED driver...

So the only con with this way is you have a power conversion in DC-DC module and LED driver...so its a bit more lossy on paper...but on the flip side, we have a digital controlled driver and smaller footprint overall.

build thread would take too long @ the moment, and I got a heap of orders on, so here is a build pic...

I used valve motion activated blue leds on my bike for a few weeks. It was very cool
