Mission

The CLU Foundation bestowed on itself the goal of

encouraging young designers to develop innova-

tive lighting concepts for exterior public spaces. To

achieve this and serve its purpose, the CLU Founda-

tion hatched the plans for a creative competition that it

holds annually since then, attributing grants to numer-

ous projects based on their merit.

Objectives

The CLU Foundation aims excellence by encouraging

conscious integration of the plastic quality of the prod-

ucts, technical advancements in exterior lighting andenvironmental respect.

Board Members

Members of the CLU Foundation share a vision for the

future: to open the CLU Foundation to the world and

to encourage the industrys next generation to ques-

tion issues that require more than developing a prod-uct as a solution; we encourage the development of

global solutions that link humans to their environment,

thanks to light.

2010-2011 EDITION

THEME : LIGHT IT FOR HUMANITY

The Context

The need for public lighting is constantly evolving

on the planet and follows the phenomenon of urban

development. If, in 1800, only 2% of the world popula-

tion lived in urban areas, today, the urban population

equals and will soon exceed the rural population in the

world. If, until the mid-twentieth century, the majority

of the worlds urban population was concentrated in

developed areas of North America and Europe, urban

growth has now shifted to development areas. Youshould know that by 2030, over 80% of the global ur-

ban population is expected to be concentrated in Asia,

Africa as well as in Latin America and the Caribbean.

Where can we nd users of street lighting? Today,

the majority of the worlds urban population resides in

small and medium towns and most city dwellers live in

smaller cities. About 16% of city dwellers live in citiesof more than 5 million inhabitants. An important data

indicates that in 2007, over 30% of the worlds urban

population - 1 billion people - lived in shanty towns,

90% of them located in development areas. These

ndings indicate that one out of three city dweller lives

in a shanty town.

More and more frequently, natural disasters disrupt

entire, and often densely populated, regions; popula-

tions see their infrastructure destroyed and must live

through a lengthy rebuilding process. These people

then have to rely on public lighting as a light source

for their safety, their economic lives and their collective

activities. Lets not forget that the most heavily popu-

lated areas are located in the warmer regions of the

planet; where people live a lot at night when the tem-

perature is milder.

For all those people devoid of a reliable source of

energy and light, lighting can ensure wealth for all

The Contest

With this contest, the CLU Foundation wishes to give

new meaning to public lighting and provoke the emer-

gence of sensitivity to the need of mankind to benet

from the available light, to share and take ownership.

The boundary between street lighting and the user can

disappear to become the service point of luminous en-

ergy to the whole community. Public lighting is a re-

sponse to the needs of human beings, and your solu-

tions will be the answer.

The challenge this year is to design lighting solutions

that can be shared and meet the most daring expecta-

tions:

- A central gathering point

- A Source and connection accessible to the entirecommunity

- A Realization that supports the vitality of social ex-

change

- A viable alternative to the use of other fuels (gasoline,

wood, etc.).

- An economical design with regard to materials and

components (3R), that is also aesthetically and cultur-ally meaningful

public lighting

Bonfre

In the ancient time, public lighting was a bonre. Bon-

re is a centerpiece for a gathering space as well as

a vehicle for ceremonies, rituals and event.


Tybee Island lighthouse

Beacon

As the society grew larger and the territory extended

to great distances, public lighting became a beacon.

Signal re is the means for communicating between

distant settlements and a lighthouse is the instrument

for guiding the sailors traveling the dark oceans.

Birth Street Lights

The advancement of technology and the development

of urban environment made possible the birth of street

lights.

Urban Infrastructure

In modern towns and cities, public lighting is one of

the key elements of urban infrastructure. It is an inte-

gral part of the urban fabric, preventing accidents and

increasing public safety.

Particle System

The term particle system refers to a computer graph-

ics technique to simulate certain fuzzy phenomena.

Examples: re, explosions, smoke, moving water,

sparks, falling leaves, clouds, fog, snow, dust, mete-or tails, hair, fur, grass, or abstract visual effects like

glowing trails, magic spells, etc.

Campfre

Reyner Banham, in his introduction to the book,

The Architecture of the Well-tempered Environment,

compares the substantial architectures erected from

inert material structures with what can be dened as

the architecture of campre with dynamic boundary

condition and negotiable characteristics based on the

changes in the context.

Initial Concept Sketch

design research

project discription

Concept

Public lighting that can become:

A gathering space for events

A beacon for communication

And an infrastructure for public safety

Sensing and Acutation

Interactivity

The proposed public lighting responds to the density

of surrounding people

The 4 PIR Motion Sensors embedded in the proj-

ect detects the presence of the people around. As

the number of sensors that are detecting presence

increases, the lighting shifts to different modes.

- 0 PIR Sensors triggered: Default mode(Random

cycling of colors)

- 1-2 PIR Sensors triggered: Mode 1(Beacon lighting)

- 2-4 PIR Sensors triggered: Mode 2(Bonre lighting)

Twitter API+Processing

Crowd sending and visualization

Crowd Sensing

The color of the lighting responds to the public

awareness on Boston safety.

- Crowdsensing: The public awareness of safety is

collected utilizing the Twitter API as source of infor-

mation.

Data Mapping

The color of the lighting changes depending on the

average of the #BostonSafety + rating in number, 1

meaning dangerous, 5 meaning very safe.

e.g. #BostonSafety 1, #BostonSafety 3, ...etc.

Arduino Mega 2560

The Arduino Mega 2560 is a microcontroller board

based on the ATmega2560. It has 54 digital input/out-

put pins (of which 14 can be used as PWM outputs),

16 analog inputs, 4 UARTs (hardware serial ports), a

16 MHz crystal oscillator, a USB connection, a powerjack, an ICSP header, and a reset button. It contains

everything needed to support the microcontroller

Processing

Processing is an open source programming language

and environment for people who want to create im-

ages, animations, and interactions. Initially developed

to serve as a software sketchbook and to teach fun-

damentals of computer programming within a visual

context, Processing also has evolved into a tool for

generating nished professional work.

Sensible Light utilizes Processing as a tool to link

Arduino with Twitter API.
