Acriche in a dynamo light?

[Calina]

Hi,

Would the SSC's Acriche be a good LED candidate to use in a dynamo light?

According to this article from LEDs Magazine, it can reach 200 lumens at 3.3 Watt ( http://www.ledsmagazine.com/press/15571 ). Admittedly it is not the most efficient LED but the fact that in can use AC directly (no rectifier needed) could be a redeeming quality.

Since this LED works with AC power, it could be use in a very simple set up to power a light from a dynamo. Unfortunately I cannot get access to SSC site for more information (I get an error message).

Any ideas or comments?

don't the specs on that call for 110-220V AC, whereas a dynamo puts out 6V AC?

Since they use about 3 Watts, I doubt that they do it at these high voltage. If this were true, they would draw around 30 mA at 110 V (half that at 220 V)!!!??? I think it's unlikely.

But as I said I don't have access the SSC site so I don't really know anything about the specs.

The site works but its hard to get anything...

Acriche
("AC"= Alternating Current, "Acro" = Top, First "riche" = Value) Top semiconductor lighting technology

Semiconductor EcoLight
Acriche series is designed for AC current-based operation. Acriche is a semi-permanent and environmental safe semiconductor lighting that can be used in AC without additional device.

Environmental Aspect
Acriche has been meeting the Restriction of Hazardous Substances(RoHS).

• Lead free (Pb free) solderability
• No Cadmium
• No Mercury

Reducing CO2 emissions
If the use of Acriche to replace general lighting sources may benefit the environment.
The transfer of electricity to light is much more efficient allowing for less energy to be expanded on a given task.
It would lead to a reduction in CO2 released by coal or gas power plants or nuclear waste produced by nuclear power plants.

For me it looks superb - 200 lumen power, from the led that you can simply stick to the electric socket :thumbsup:

Thank you for the information.
Certainly an interesting LED but it is not going to work for a bicycle dynamo light :sigh:.

I'm not sure whether it would actually work or not, but I've looked at the unloaded output of my Schmidt SON hub and it will put out over 100 volts AC. It would be interesting to hook one up and see what happens.

I'm sure it would be possible with the right circuit to reach the needed voltage, no problem but when I started this thread, I was kind of hoping it would be possible to hook it up directly to the dino with nothing more than a resistor.

It would be interesting to see if a dino hub could power it directly, though I have doubts.
