| Title: |
Methods and Apparatus for Simulating Resistive Loads |
| Abstract: |
Methods and apparatus for simulating resistive loads, and facilitating
series, parallel, and/or series-parallel connections of multiple loads to
draw operating power. Current-to-voltage characteristics of loads are
altered in a predetermined manner so as to facilitate a predictable
and/or desirable behavior of multiple loads drawing power from a power
source. Exemplary loads include LED-based light sources and LED-based
lighting units. Altered current-to-voltage characteristics may cause a
load to appear as a substantially linear or resistive element to the
power source, at least over some operating range. In connections of
multiple such loads, the voltage across each load is relatively more
predictable. In one example, a series connection of multiple loads with
altered current-to-voltage characteristics may be operated from a line
voltage without requiring a transformer.
