LUZ Lexus Design Award 2015

DESIGN

 LUZ

LUZ is an ambient light for indoor use that fluctuates in intensity of brightness and colour gradient depending on the weather conditions and time of day. the ´´light“ interacts with nature and removes the barrier between the inside and the outside of a home.  It is a living object, that uses a simple internal brain to transform the atmosphere of a room in a subtle but powerful way.

LUZ was inspired by my own experience living in northern Europe for two years, this is a photograph of the view from my window. As winter approached the days became shorter and the weather was more cloudy, rainy and snowy. Quickly I realized that my friends mood and my own mood were saddened by the lack of daylight.

Window view

I could not stop thinking about my sunny hometown and the physical and emotional warmth you can feel in that society. So I started to develop the design of a luminaire where the ´´light“ interacts with nature and removes the barrier between the inside and the outside of a home. I wanted the light to be alive, and to breathe life into the home.

I designed a circular lamp with a ’T’-section profile and two RGB LED strips which wrap around the circumference , one attached to the outer surface, and another one to the inner one. The LED strips are shaded by the extruded profile and illuminate the wall both inside and outside of the ring.

Principal

Both LED strips are connected to an open source micro controller that receives data ( luminosity and the colour temperature) about the outside atmosphere sent wirelessly from a sensor placed by the window.
Then, the micro controller translates the information into RGB light colours.
For example, when it is cloudy, the lamp will be bright orange, simulating the sun, and when it is dark outside, the lamp could be bright blue and refreshing.

While developing LUZ I have been in constant conversation with people affected psychologically by lack of sunshine and natural daylight, they chose the default light-colors provided in LUZ, However, at the moment we are developing an app with which you can change the colors of the lamp depending on the weather conditions, you can share them online, expressing your emotions on your choice and compare them with people from all over the planet whose environmental conditions and emotions are totally different.

TECHNOLOGY

 

Electronic Design

Luz design has evolved from contemporary rapid prototyping techniques to formal industrial production, during this journey different technologies have been tested, modified, hacked and specified.

All hardware and assembly design have been developed in Germany (Leipzig) and Great Britain (London). A professional Spanish Software Engineer coded the different wireless technologies working on multi platform systems (Linux, OS X, Windows) in order to make this project compatible with different portable devices. A simple product, blended into the wall to let in light all its prominence. Related symbolically with simple natural elements such as the sun or moon.A mimetic and architectural light, which provides a warmth luminous sensation and makes you reflect about the importance of light and chromaticism in our daily life .

LUZ is an intelligent lamp formed by a professional light sensor that measures in real time the intensity of the light and the color tª values outdoors which are processed by a micro-controller. Offering more than 60.000 potential colors with 2 mode sensor analysis controlled by a wireless device or an Android/iPhone app.
