This document summarizes an RGBA luminaire project created by students at Boston University. The luminaire consists of red, green, blue, and amber LEDs embedded in a fiberglass frame and controlled by an Arduino microcontroller. The Arduino allows commands to be sent via Ethernet to control the brightness and color of each LED. This creates a controllable lighting system that could improve energy efficiency and provide health benefits. Future improvements may include lighter frame materials, integrated lenses, and more customized lighting settings. The luminaire draws 68W of power and produces up to 2200 lumens of adjustable color light.

While light levels may be objectively measured, how we perceive light is entirely subjective. Light affects us on a primal emotional level. On a biological level, our brains are hardwired for long nights huddled around camp fires. More than just cycles of light and dark, color temperatures tied to the sun’s appearance at high noon and sunrise/sunset play a central role in regulating our body’s biochemistry. How light affects us changes throughout the course of our lives, can be culturally dependent and is ultimately, entirely personal. In order to illicit the desired emotional response, a lighting designer needs to be able to make choices about where, when, and what kind of light to put on any given surface. These choices need to be perfectly reproducible but also flexible and able to adapt to changes in ambient conditions and space usage requirements. This is what a lighting control system does. Designing a lighting control can be hard. Yes, it requires a thorough understanding of the technology, but that is not what makes it hard. What makes it hard is understanding how best to apply the technology within the context of the entirety of the job. What does the system need to be able to do, both now and in the future? How, and by whom, is the system is going to be used on a daily basis? What sort of special events, overrides and/or automatic triggers may help the space achieve the client’s desired level of efficiency? First and foremost, have you guaranteed that someone with no formal training or experience can easily turn on the lights? And what about the budget? It is easy to assume that hard means expensive. While that may be true for certain projects, it is by no means universally true. As I mentioned above, the difficult part is developing the detailed narrative. The actual equipment and installation required may not be very expensive in the scheme of your project. In fact, part of good design involves finding elegant solutions that streamline parts, pieces and installation requirements. A well designed system, tailored for your project and your needs, should cost less than a generic system capable of “doing it all.” Often, after careful analysis, a basic time clock and some presets may be all that a project needs. Make controls parts of your initial design conversation. They may not seem glamorous, but they give life to your design. They are the first thing your client experiences when they enter the space and the last thing they touch when they leave.

Abstract
Increasing population places increasing demands on energy supply, which leads to heavy power deficiency. We can supply only a
limited amount of energy to the consumers because we have only limited conventional sources of energy and non-conventional
energy sources are mostly still under research and have not been deployed on a large scale. Not only there is limited amount of
energy to be supplied to the consumers but heavy demand of energy supply also leads to environment degradation. This creates a
need to use the limited energy efficiently. This has given rise to new trend towards reducing the energy consumption: Green
Buildings. About 40% of the energy consumption in the world is consumed by buildings [1]. Energy consumed by lighting systems
accounts for about 15% of total energy consumption of buildings [1]. Thus we need to use energy efficient lighting devices for
illuminating buildings. Thus in this study we to tend to develop optimized energy efficient system, which will use LED lights to
illuminate buildings. The illumination intensity of the LED lights will be decided by the FPGA, which is interfaced to the LED
driver. Based on combined values of light intensity of the room and occupancy of the room using different sensors, the light output
of the LED will be controlled.

The Role and Disruptive Impact of Wireless Lighting Controls - Presented by B...Cindy Foster-Warthen
Lighting Controls play a key role esp. in connection with the new changing energy standards. Traditional and wired systems are often outside clients budgets. Wireless systems are emerging offering affordable accessible, often DIY controls. There are different wireless systems and protocols ranging from Zigbee to JenNetIP as well as mixed systems. We would like to give an overview on how they work, outline technological pro and cons, describe new functionalities and highlight how they go beyond the traditional lighting manufacturer approach. In addition many new personalized controls come to market in connection with the SmartHome. Lighting Controls are now accessible, affordable for everyone and not just for the high-end market. We like to give an overview over the current emerging systems and how they differ from legacy systems.

The RGBA luminaire is made of red, green,
blue and amber colored LEDs. This light is able
to change colors as well as dim or brighten.
Introduction
The ability to control lighting is an important
step in improving energy efficiency. If we can
provide customized lighting that offers exactly
what we need, when we need it, we will be able to
save large amounts of electricity, without
compromising our work or home environment.
Furthermore, by being able to change the color
and intensity of the light, we are able to provide
some health related benefits. Many people who
work in-doors do not get enough exposure to the
sun on a daily bases, affects vitamin D absorption
in the body. This problem can be fixed by more
exposure to right frequencies of blue light.
Another benefit of this, is mood improvement,
which can lead to a great increase in productivity.
Project Code ( A2.1.3 )
• Energy Sustainability
• Health, Safety, and well-being
• Increased Productivity
- Luminaire consists of 48 LEDs in total,
mounted evenly onto 8 thin PCB boards.
- Each board has a heat sink attached to the
back.
- Fiber glass outer frame provides structural
support and insulation.
- The Arduino is attached to the side of the frame
for easy access to ethernet cable and power
source plug-ins.
Through sending commands to the Arduino we are
able to dim, brighten or turn off completely, any color of
LED we wish to change. This is made possible by
changing the duty cycle, or on to off ratio, of the LEDs,
thereby changing the rate of flickering of the lights, also
known as PWM. This flickering doesn’t appear as a flicker
to the human eye, instead, it is perceived as dimming, or
brightening.
The Arduino is the embedded controller for the
RGBA luminaire. Basically, the Arduino waits for a
command from a connecting program (client), and
implements the command to an IP addressed set
of LED colors. Essentially the Arduino acts as a
server.
Here is a basic explanation of how we control the
luminaire through an Arduino:
- C/C++ is used to program the Arduino.
- Using the ethernet cable connected between the
Router and the Arduino, an IP address is assigned to the
Luminaire.
- The Arduino receives commands from the client in the
form: r###, through an external program such as
PUTTY.
- The first letter of the command represents color, the
following number ranges from 0 to 255 and represents
the brightness of that color of LEDs.
- The Arduino dims the LEDs through PWM.
Our motivation for this project was to provide a
versatile and IP-enabled color-controllable light
for future work. Also, this light was designed to
support one of Boston University’s senior design
teams’ projects. With this light, we are able to
further explore the control aspect of smart lighting.
- Customization: now that we have successfully
created the program to dim or brighten any
color at will, more customized settings are to
come.
- While the fiber glass provides strong structural
support, it is too heavy. The next luminaire will
be made of thinner strips of fiber glass, perhaps
even wood.
- Trace amounts of led can be found in a few
components used to build the lamp. Future
lamps will be led-free.
- Currently the luminaire has no light filters,
resulting in extremely bright light. With the right
lenses, color mixing abilities will be improved,
and the brightness will be less harsh.
A small lens that fits
over the small LED.
A possible addition to
future Luminaires.
With the 12 V power supply turned on, the Luminaire
draws roughly 68 W of power. The intensity of the light can
go from 0 (all LEDs turned off), to 2200 Lumens (all LEDs
turned on).
