Zigbee operated phase control lighting controller with sensors

A wireless operated led lighting controller has both analog and phase control outputs which operate a dimming luminaire, and sensors for lighting and motion which operate autonomously as needed. In addition it is locally operated by a handheld infra-red controller. ... Eptronics Inc

Wireless lighting control module

A zigbee lighting control module is described which can be connected to the input of an analog dimming led driver so that a zigbee controlled analog signal can be applied to the dimming input of the led driver. Particular features of the module are the capability to apply a chosen nonlinear transform between the digital zigbee input signal and the 0-10v analog output signal, and the use of a relay to cut off power to the driver being controlled when the analog output signal goes below a chosen level. ... Eptronics Inc

Programmable led driver with mesh network wireless interface

An led driver includes a first stage. The first stage converts ac power from an ac power source into a dc power source. ... Eptronics Inc

Programmable led driver

An led driver comprising a first stage, wherein the first stage converts ac power from an ac power source into a dc power source. A second stage receiving the dc power source from the first stage and further comprising: a second stage step-down buck converter with a constant current output that receives power from the dc power source; and a second stage intelligent step-down led driver chip that runs a step down buck converter that produces the constant current output to the external led load. ... Eptronics Inc

Ac led light engine

A light engine driven directly from the ac power line has multiple series connected arrays of leds each with an associated current limiting transistor. The current from each current limiting transistor goes through a corresponding current sensing resistor and all these resistors are connected in series. ... Eptronics Inc

Led driver with auxiliary power output

An led driver has a primary side regulation with at least one input connected to the ac power line, and at least two outputs. At least one output is for driving leds and at least one output is for providing auxiliary power for associated circuits. ... Eptronics Inc
