| Title: |
LED-Based Lighting Network Power Control Methods and Apparatus |
| Abstract: |
Multiple lighting apparatus coupled together to form a lighting network,
in which operating power is efficiently provided throughout the network
based on a distributed DC voltage or a distributed AC voltage. Based on
various power driver configurations, each lighting apparatus incorporates
one or more power drivers for one or more LED-based loads. In one
example, a controlled predetermined power is provided to a load without
requiring any feedback information from the load (i.e., without
monitoring a load voltage and/or load current). In another example, a
"feed-forward" power driver for an LED-based light sources combines the
functionality of a DC-DC converter and a light source controller, and is
configured to control the intensity of light generated by the light
source based on modulating the average power delivered to the light
source in a given time period, without monitoring and/or regulating the
voltage or current provided to the light source. In various examples,
significantly streamlined circuits having fewer components, higher
overall power efficiencies, and smaller space requirements are realized.
