Dimmer control system having remote infrared transmitters
First Claim
1. A control system comprising:
- at least one electrical load control device responsive to command signals in the form of radiant energy; and
a transmitter for producing command signals in the form of radiant energy for receipt by the at least one electrical load control device, the transmitter comprising a pair of conductive terminals for receipt of command signals in the form of electrical signals, the transmitter further comprising two sets radiant energy generators each having a polarity for connection to an electrical circuit, the radiant energy generators operably connected in an electrical circuit containing the conductive terminals, the generators connected to the electrical circuit such that the polarity of the generators of one of the sets is reversed with respect to the polarity of the generators of the other set, the radiant energy generators further connected to the electrical circuit such that the sets are connected in parallel with one another.

Abstract
A control system includes an electrical load control device responsive to radiant energy and a transmitter. The transmitter includes two sets of radiant energy generators connected to an electrical circuit such that polarity of the sets is reversed. A transmissive enclosure includes indented portions defining deflectors oriented obliquely with respect to a generator support surface. The transmitter is secured to a bracket for attachment to a backcover of the load control device. The control system may also include a master control generating an electrical control signal in response to an actuator or in response to a radiant energy signal. The control system is capable of limiting the master control to generate a signal only in response to the actuator. A power supply for the transmitter includes a filter network having a filter capacitor and resistor in series with a power supply capacitor and a diode in parallel with the resistor.
