Automatically reconfiguring light-emitting circuit

An automatically reconfiguring light-emitting circuit, the circuit comprising:

• a first block of electric lights;
• a second block of electric lights;
• a switching mechanism, the switching mechanism having (i) a first state in which the switching mechanism electrically connects the first block of electric lights in parallel with the second block of electric lights and (ii) a second state in which the switching mechanism electrically connects the first block of electric lights in series with the second block of electric lights;
• a current regulator that generates a current control signal in response to a current in the first group of lights and second group of lights;
• and
• a controller electrically connected to the switching mechanism, the controller configured to switch the switching mechanism between the first state and the second state based on the current control signal;
• wherein the current regulator comprises at least one power transistor through which the current in the first group of lights and second group of lights flows, the at least one power transistor having a control terminal;
• and the current control signal is a signal at the control terminal of the at least one power transistor.
