LED Array

We plan to use many of these LED Arrays. We will need to drive them directly from multiple types of power generators. Thus the need to be designed to withstand larger than normal voltage fluctuations. A basic array could be manufactured that runs at 12 (or 6) volts DC. It could have a double connector plug on it so that it could be plugged into other like arrays using say connector "A" and end up running on 12 Volts DC (Arrays connected in parallel) source or if plugged into the other connector "B" it would run on 120 volts DC (10 arrays connected in Series) power source. This would satisfy 12 and 120 Volts DC power sources. To run on AC one would have two of the resultant 12 volt or 120 DC assemblies, with the second assemblies (Diodes one way flow) conducting in the opposite direction to balance the electrical load on the AC source.

120 volts is more readily available and uses much smaller wire to bring the power from the generator (windmill, water wheel generator) to the light array. Each array may drop 12 Volts but 10 or more will be put in series to hook directly to a 120 AC or DC source. Each array will still have the same 12 Volts across it no matter the ultimate source voltage. Most houses today use 120 Volt capable fixtures, so this becomes easy to find wire and fixtures.

As a consumer who would be extremely interested in purchasing such a light, I would say that that the major purchasing considerations in order of importance are: Low cost, energy efficient with lots of resultant plant growth, long life, able to withstand larger than normal voltage fluctuations, able to run on 120 Volt and 12 Volt AC or DC, easy to add on multipliable arrays to get as much light as needed. The power sources for these units will often be windmills and water power, with a resultant expected fluctuation in over all voltage to be larger than standard on the grid power. I believe that frequency and intensity of each light array would not need to be controlled but could be set to full on for most efficient operation under the above considerations.
