FIREFLIES & TECHNOLOGY

Thanks to the internal structure of fireflies, scientists have been able to improve the original LED, where little success has been achieved in the past.

FIREFLY

Fireflies fall under the family beetles, they are also known as fireflies or glow worms. There are around 2000 species and thanks to the light they are known all over the world. Fireflies have the remarkable property of independently producing light, a process called bioluminescence. In special organs in the abdomen, the pigment luciferin is oxidized in a biochemical reaction by the enzyme luciferase, producing light. Beneath the layer of light-producing cells is a layer of cells with small crystals that reflect the light to the outside.

NICK HOLONYAK JR.

In 1962, the first light-emitting diode (LED) was developed by the American physicist Nick Holonyak Jr. at that time he was employed as a scientist in the General Electric Company laboratory in Syracuse New York. Nick Holonyak Jr. has received awards for various studies including the IEEE Medal of Honor, an award that is only awarded when there has clearly been an exceptional contribution to science and technology.

FAILED ATTEMPT

Scientists from the Korea Advanced Institute of Science and Technology have already made an attempt to apply the structure of fireflies to the development of LED lights. In this research they simulated the insect's biological nano-structures and incorporated this into the LED lights, unfortunately, they did not get beyond a 3 percent light increase.

NEW ATTEMPT

A new study was published this week in the Optics Express, which shows that fireflies reflect light internally in the same way as man-made LEDs. The scientists have therefore assumed that when the serrated scales improve the light of a firefly, they will probably also have an equal effect on LEDs. They appear to be right. Thanks to the improperly fitting scales and the abrupt profile that is created as a result, there is a diffuse transfer of light which enhances the light intensity. Using this information, they have managed to develop a new coating that can even be applied to all existing LEDs. When this coating and lamps with which the coating has been applied are brought onto the market, there is still no insight into it.

From the tunnel to the zoo

From the tunnel to the zoo LED IN THE AMSTERDAM-EAST RAIL TUNNEL From August 2013 you can imagine yourself in a different world in Amsterdam East, South Africa. Moving contours of animals from the South African wilderness appear on the walls of the railway tunnel. Pitch won Stadsdeel Oost last year wrote a pitch to give the tunnel between the Oosterparkbuurt and Transvaalbuurt a new look. The results were announced after exciting months of patient waiting. With 62 percent of the votes, the artwork has won from LED , the design comes from NIO architects. The underlying idea Replacing a civil work of art with a visual work of art is not a simple task. How do you turn an anonymous tunnel into a meaningful space? By taking visitors to another place. The tunnel on the Tugelaweg lends itself perfectly to a temporary experience that makes you mentally in a different place. How?  The walls of no less than 40 meters long present themselves as windows through which you can becom...

Light plan - The basis

Light plan - The basis THE BASIS OF A LIGHTING PLAN Lighting can make or break the atmosphere in your home, just think of a restaurant that is too bright or a workplace that is too weakly lit. But in addition to the aesthetic, lighting also has a practical function. To realize the ideal lighting in your home, developing a lighting plan can be a solution. To develop a lighting plan, the basic principles and points of attention per room must first be known, our LED experts explain this to you in a series of blogs in which we devote the last article to developing a lighting plan. In this first blog article, we start with the 4 types of lighting that are used within the interior architecture. 4 TYPES OF LIGHTING Light has various purposes and in the various, often multifunctional rooms, it is important that sufficient attention is paid to lighting. It is therefore important to distinguish between the different types of lighting, there are 4 in total: General lighting This is also...
