Commercial and Residential Lighting Control Solutions

As energy efficiency standards increase and countries strive to produce more green energy, lighting companies across the world are implementing more and more controls into Lighting Solutions. Lighting applications can range from occupancy detection to centralized lighting controls with the goal of reducing energy consumption across multiple platforms. Panasonic technologies used in leading Lighting Controls include Passive Infrared Sensors, Light Sensors, Resistors, Relays, Switches and more. Lighting Controls will drastically strengthen their position in the market going forward in areas such as commercial (i.e. hospitals, parking garages) and residential buildings.


Find Out Why A Relay Should Meet The New NEMA 410 Standard.

 

NEMA is a standard that defines the worst case inrush current expected from Lighting Control Switches/Relays to be used with electronic drivers and discharge ballasts. This includes both self-ballasted compact fluorescent lamps and integrated LED lamps. NEMA specifies that any 20A devices are tested with a 16A load representing 80% of the branch circuit rating.


Panasonic Solutions for Lighting Controls

Panasonic offers a solution-based approach by providing a wide variety of electronic components for Commercial and Residential Lighting Controls including Relays, Capacitors, Bluetooth® Modules, Resistors, Sensors, Switches and more. Click on each image below to learn more about various Lighting Control applications.

Centralized Lighting Control

A Centralized Lighting Control System incorporates communication between multiple system inputs and outputs with the use of a central computing device. It helps to provide the appropriate amount of light as needed in designated areas. In building automation systems, it is common to see the Relay that controls lighting loads placed in the main network controller module that may be subject to other peripheral devices such as ventilation, shades, or HVAC devices.

High inrush current is often seen in these types of Lighting Controls.  For either conventional power supply or switch mode power supply, a smoothing Capacitor is used right after the bridge rectifier. This Capacitor causes the inductive load which accelerates the life of the contacts.  As a counter measure, many modern Lighting Controls incorporate an algorithmic logic from a micro-controller to implement zero-cross switching.  In order to implement zero-cross switching more effectively, Latching Relays, such as Panasonic’s DJ-H or DW Series, are used.  The polarized magnet found in Latching Relays helps provide consistent turn-on time for closing the contacts.

The chart above demonstrates Zero Cross Switching.

Occupancy Detection

An Occupancy Detection device senses the presence of a person (or living thing) in a space. The Sensor(s) in this device are used for people detection as well as energy savings. Many control systems use Occupancy Detection devices to turn Lighting Controls on/off depending on whether the room is occupied by a person. Technologies used in this application include Passive Infrared Sensors or Thermopile Array Sensors (Grid-EYE®).

Dimming Control Board

A Dimming Control Board electrically controls the dimming and ON/OFF functions of a Lighting system. Technologies used in a Dimming Control Board include Relays, Occupancy Sensors, Current-Sense Resistors, and Aluminum Electrolytic Capacitors.

Touchpad/Keypad System

A Touchpad/Keypad System is a Human Interface System that can be used to control the Lighting system by a user. Functions could include turning lights ON/OFF, dimming lights, setting up timed lighting schedules and more. Technologies included in this application include Light Touch (Tactile) Switches, Connectors, Encoders and Transparent Touch Panels.

Wireless Network Bridge Controller

A Wireless Network Bridge Controller is a device that manages Wireless Communications and signals to control light system components such as Switches, Sensors, Emitters and more. Technologies include Bluetooth® or Wi-Fi modules.
