Energy or particles emitted from a source and moving in the air are called radiation. Radio waves, microwaves, X-rays and gamma rays are types of electromagnetic radiation. Visible light is also a kind of electromagnetic radiation. However, this constitutes only a small part of the electromagnetic spectrum.

LED lights are used almost everywhere due to their long life, low energy consumption and flexible application possibilities. LEDs, which we are used to seeing in the streets, commercial buildings and workplaces, have now entered our homes and even our bedrooms. So how do LED lights affect our sleep quality?

DALI stands for Digital Addressable Lighting Interface. DALI is digital technology that provides two-way data communication for lighting systems. DALI is an automation system that is widely used especially in commercial buildings.

Scientifically proven that natural lighting helps people become more happy, calm, healthy, and productive. In addition to this fact, using this sustainable light source in lighting design reduces the need for artificial light and consequently energy consumption.

Smart city is the name given to cities that use information and communication technologies (ICT) to improve the quality and performance of urban services such as energy, transportation and public services. The inclusive aim of a smart city is to increase the quality of life for its citizens with smart...

T5 and T8 fluorescent tubes are often used for ambient lighting in commercial areas such as offices. T5 fluorescent light bulb is a newer technology than T8. T5 fluorescent light bulb has an efficiency of about 100 lm/W. T8 fluorescent light bulb can reach about 90 lm/W luminous efficacy.

Illumination is just one part of lighting design. Darkness, without the touch of light and shadows, has a magical role in the total composition of a design. Light creates shadows and shadows enrich the objects and accordingly the total aspect of the environment.

OLED (Organic LED) is solid state lighting (SSL) technology like LED. OLED is made of carbon-based thin organic layers that are compressed between two electrodes. LEDs are made of different types of heavy metals (arsenic, gallium, indium).

Biomimicry is a combination of the Greek words Bios (life) and Mimesis (imitation) and it means imitating life. Biomimicry is a discipline that mimics nature's designs and processes to create a healthier and more sustainable world.

RH is a redesigned retail and hospitality building in New York City’s Meatpacking District. The original building, from 19th century, was with two levels and served as stable and garage. Interior lighting of RH is based on an approach of using fewer light sources, and creating a sense of home...

With the current global pandemic on everyone’s minds, more attention is being paid to the role of many useful technologies that have been previously underutilized in controlling the spread of infectious disease. Among these technologies is germicidal UVC technology.

Light pollution is a side effect of the industrial civilisation and the result of ineffective lighting. Luminaires that project light upwards or to the sides cause the night sky to constantly illuminate. A poor lighting design causes following components of light pollution; glare, sky glow, light trespass and clutter.

Unfortunately this year, like several other organisations, Luminale also is cancelled due to the current requirements of the health authorities about SARS-CoV-2 virus. But luckily, many of the works have been documented by the artists during creation phases.
