You want a maximum power point charger. We had discussed this before, but I do not remember if you wanted them on all the time or how much power you needed.
The Charge Controller I use work in that principle.

Oh yea, the traffic light. LEDs don't need regulated power just current limiting.
For LEDs... Just a resistor to limit the current.
Yes. You need to read up on LED basics. Have you never worked with LEDs before?
??? Do your LED traffic lights require 220V or 12V?
It was a good suggestion. You could also wire up an LM317 as a current regulator instead of the resistor in series with the LED. For what reason is it not acceptable to you? Does your traffic light only have LEDs in it? are there other circuits? Relays? ICs?
A current regulator changes the voltage to maintain a certain current.How is it possible to limit current with out regulating the supply voltage?
OK are your traffic lights 220V or 12V?
HV9910 will run on 8-500V, though the inductor selection is not so forgiving.So you understood that the statement "after connecting a resistor we can apply any voltage " is wrong. So variation of the supply voltage from 11 to 15V will cause a current variation. That is not acceptable to me due to some reasons. I wanted to know a method to regulate my voltage. Of course a DC-DC converter may solve. But expected to hear an expert opinion in the forum. I know there are people in this forum who give good suggestions.
A current regulator changes the voltage to maintain a certain current.
If the load is a high resistance then the output voltage of a current regulator goes high.
If the load resistance is low then the output voltage of a current regulator goes low.
If the output is shorted then the output voltage of a current regulator is zero but the regulated amount of current stays the same.

I am sure that he is not an Indian. A person who knew the meaning would not have called you by that name. Probably he might have considerd it as an abusive word.A salesman at work called me an Audioguru. I didn't know that a Guru was from India and I didn't know anybody from India.
What is the difference between 'inexpensive' and 'cheap'?Cheap? You mean cheep like the sound from a baby bird?
All electronic parts are inexpensive in Canada. Cheap parts come from China and India.
