Intelligent Lighting and Control
Summary
Microchip can meet the technical needs of lighting engineers with its large array of 8-, 16-, 32-bit
PIC® microcontrollers, analog, wireless, and human interface products. With advanced peripheral
integration and support for all lighting technologies, a scalable Microchip solution provides
significant flexibility versus that of a pure analog or ASIC implementation. Designing with
Microchip-based intelligent lighting solutions and control enables innovation that expands lighting
product capabilities and provides product differentiation.
Light-emitting diode (LED) and fluorescent technologies are currently at the forefront of delivering
the most efficient alternatives to incandescent lighting. Although both pose technical challenges,
they also offer significant advantages beyond simple incandescent light bulb replacement,
including improved efficacy (lumens/watt), reduced energy consumption and the ability to
add intelligence.
Because the light quality of these alternate lighting technologies is perceived
to be similar to that of incandescent lighting, the benefits of longer life and
increased energy savings may not always be considered significant enough
to motivate changes in the market. Microchip’s advanced lighting solutions
offer you the opportunity to incorporate non-traditional capabilities into your
lighting designs. Features such as predictive failure and maintenance, energy
monitoring, color and temperature maintenance and remote communications
and control are just some of the advanced capabilities that can make intelligent
lighting solutions more attractive. These advanced capabilities—along with
reduced operating, maintenance and energy costs—can quickly translate to
significant savings, particularly for corporate and commercial facilities.

Lighting Technology Basics
Incandescent Lighting Technology
Advantages
Disadvantages
■ Cheap
■ Large amounts of visible light
■ No electronics required
■ Poor efficiency
• ~10% input energy = light
• ~90% input energy = radiated heat
• 10–30 lumens/watt (efficacy)
■ Short life: 1,000–2,000 hours
Incandescent light sources are good at creating large amounts of visible light and even greater
amounts of heat. As a result, a typical light bulb is not very efficient—only about 10% of the
input energy is output as light with the remaining 90% being wasted as radiated heat. The
typical light bulb has a relatively short lifetime—ranging from several hundred to a couple
thousand hours—as the extreme heat of the tungsten causes it to evaporate and eventually fail.
Fluorescent Lighting and HID Technology
Advantages
Disadvantages
■ Relatively inexpensive
• ~75% less energy than incandescent
• More than 70 lumens/watt (efficacy)
■ Increased life: > 8,000 hours
■

Typically requires “warm up”
Can contain mercury
Sensitive to environment and orientation
Moderate light quality
Typical fluorescent lighting operates by driving a current through a glass enclosure
containing an inert gas and mercury. With the help of phosphors, these elements
create visible light when they are excited by electricity. High intensity discharge (HID) lamps or arc lamps are similar in
function but create visible light through electrically excited gases (plasma) without the use of phosphors. In both glowdischarge lamps and HID lamps, a ballast is required to initiate and maintain this electrical reaction. The ballast kickstarts the electrical-gas reaction with a large amount of energy and then regulates the current back down to a normalized
operating current. High-resolution PWM control is required to accurately control this reaction as well as provide smooth
dimming control.
LED Lighting Technology
Advantages
Disadvantages
■ Best overall efficiency
• ~25–50% less energy than fluorescent
• More than 100 lumens/watt (efficacy)
■ Longest life: > 50,000 hours
■ No “warm up”, no radiated heat
■ Good in indoor and outdoor applications
■ Requires active or passive thermal
solution to remove conducted heat
Similar to a traditional LED, a High Brightness Light Emitting Diode (HBLED) produces light
when forward biased, enabling the electron-hole recombination that releases light photons.
LED light output is a direct function of the current flow—too little current and the light
will dim, too much current and lifetimes will be shortened. A typical LED driver is a DC power supply providing converted
AC or DC power to directly control the LED via constant current, Pulse Width Modulation (PWM), or other variations. The
LED driver must also provide high efficiencies and power factor correction (PFC) while providing protection from AC line
voltage fluctuations.
LED drivers can be designed to offer dimming and RGBW color mixing capabilities by either providing a high resolution PWM
(or variants such as VFM—Variable Frequency Modulation) signal or varying the constant current.

Intelligent Lighting and Control Solutions
Peak Efficiency
Intelligent Lighting Controls
No matter which lighting technology is used, the ability to effectively control the light source is essential. Replacing a simple on/off
switch, advanced lighting control provides the opportunity to incorporate additional intelligence and increase energy savings.
The ability to dim any light source is the most common requirement of a light controller, but it is also a potential design
obstacle. Most legacy dimmers are simple TRIAC dimmers that can vary the light output of an incandescent light source
from 0–100%. These vary the brightness by “chopping” the AC line voltage and controlling the effective power to the lamp,
thereby varying the light output. This method functions well with incandescent sources, as well as with some specially
designed CFL ballasts, but does not function properly with most conventional drivers or ballasts. In order to effectively
dim LED and fluorescent light, specialized methods such as varying PWM frequency or variable current is required. This is
easily implemented with electronic dimming controllers.
Functions such as dimming and timers are becomming commonplace, but intelligent control provides opportunities to
enrich the user experience and increase value. Incremental energy savings can be provided by integrating elements such
as energy management and harvesting (ie. solar), ambient light compensation (reducing light output based on other
localized light sources) and occupancy or motion sensing. Intelligent control enables the creation of lighting networks that
communicate locally as well as to remote locations to increase energy savings further and reduce maintenance cost via
items such as fixed light output in lighting arrays (ie. street lamps, large rooms, etc.), monitoring light output and providing
real-time operating issues. Lighting can also be integrated into other system topologies including security systems or
automation and control. Aesthetically, lighting control supports custom mood lighting designs which can vary brightness,
color and color temperature across large lighting arrays.
Using Microchip’s intelligent light and control solutions, you can integrate a variety of enhanced capabilities into the
luminaire ballast/driver, wall controller or remotes to create additional product differentiation. You are limited only by your
creativity in designing differentiated products that offer customizable user interfaces and improved user experience.

0–10V
Ethernet
0–10V is the simplest and most prevalent lighting
communication protocol. Scaling from 0 to 10V,
communication is based on varying the voltage levels. This
is useful for dimming, as well as responding to external
input sources, such as sensors, remotes, wall-box controls
and automation.
Ethernet connectivity is becoming ubiquitous. As lower-cost
solutions are now more available, it is becoming easier to
use Ethernet for even the simplest control and diagnostic
applications. Learn more at www.microchip.com/ethernet.
Digital Addressable Lighting Interface (DALI)
DALI is a standard lighting control protocol for large
networked lighting systems. DALI provides bi-directional
communications with uniquely addressed light sources.
This allows for customized lighting schemes and the ability
for the light source to relay output level, color and other
information back to the controller. Microchip offers FREE
DALI code libraries to simplify development—available at
www.microchip.com/lightingcomms.
Digital Multiplex 512 bytes (DMX512)
DMX512A is another successor to 0–10V which provides
dimming communication. Used heavily within stage
and theatrical lighting applications, DMX512A provides
unidirectional lighting communication and control of
various stage effects. Microchip offers FREE DMX512A
code libraries to simplify development—available at
www.microchip.com/lightingcomms.
CAN and LIN
CAN and LIN protocols were originally created for the
automotive market. CAN was designed as a high-reliability
and high-speed protocol (up to 1 Mbit/s) for the harsh
environment of the car electrical bus. LIN was later added
as a simple low-cost alternative for the control of non-critical
modules on a vehicle. Due to their inherent robustness,
these protocols are becoming more commonly used in
non-automotive applications, specifically within industrial
and commercial lighting environments. Learn more at
www.microchip.com/LIN and www.microchip.com/CAN.

networking. Specifically designed for low-cost and
relatively low-bandwidth automation applications, it
allows for quick deployment of flexible network topologies
including star, cluster and mesh. Learn more at
www.microchip.com/zigbee.
MiWi Wireless Networking Protocol
The MiWi wireless networking protocol is the most
cost-effective wireless protocol designed for low-datarate, short-distance, low-cost networks. Fundamentally
based on IEEE 802.15.4™ for wireless personal area
networks (WPANs), the MiWi wireless networking protocol
is Microchip’s proprietary RF protocol with FCC-certified
modules—providing an easy-to-use and low-cost
alternative for wireless communication. Learn more at
www.microchip.com/miwi.
