POWER SUPPLY

BACKGROUND

Overcurrent protection circuits are typically provided for fixtures that may be vulnerable to conditions such as overload, short-circuit or ground-fault. Controllable light emitting diode (“LED”) lighting can be designed with branches of circuits that are controlled by a common controller circuit. The branches may be connected to, or disconnected from, the circuit by a user. The branches may be selectable by the user, such that the controller circuit may interface with different loads for different branches. Individual over-current protection is typically provided for each branch. The maximum allowable current for each individual branch, n, of the N branches may be the maximum allowable current through the controller circuit divided by N—an average maximum in current.

It may be desirable, therefore, to provide overcurrent protection that is common to all the branches. It may also be desirable to provide overcurrent protection, that a single branch is not limited to an average maximum current.

All ranges and parameters disclosed herein shall be understood to encompass any and all subranges subsumed therein, every number between the endpoints, and the endpoints. For example, a stated range of “1 to 10” should be considered to include any and all subranges between (and inclusive of) the minimum value of 1 and the maximum value of 10; that is, all subranges beginning with a minimum value of 1 or more (e.g. 1 to 6.1), and ending with a maximum value of 10 or less (e.g., 2.3 to 10.4, 3 to 8, 4 to 7), and finally to each number 1, 2, 3, 4, 5, 6, 7, 8, 10, and 10 contained within the range.

Thus, apparatus and methods providing power to LED lights have been provided. Persons skilled in the art will appreciate that the present invention can be practiced by other than the described examples, which are presented for purposes of illustration rather than of limitation.
