White light used in homes, offices and outdoors affects people's biological clock and disrupts sleep patterns due to the high blue light it contains. High and prolonged exposure to white light causes toxic stress on the retina, negatively affecting visual performance.
The 11th Amsterdam Light Festival will take place from December 1, 2022, to January 22, 2023. This year's topic is Imagine Beyond. The 20 selected ideas among hundreds of concepts prepared within the scope of the theme will be exhibited on the city's canals at the festival.
Both ordinary light and laser light are electromagnetic waves. Ordinary light is a mixture of electromagnetic waves of different wavelengths. Laser light is monochrome. Ordinary light is non-directional and inconsistent, while laser light shows directional and highly consistent distribution. This is the main difference between ordinary light and laser light.
Whether we want to use LED light bulb in our house or in a project, we generally have a complexity like how many watts and lumens that we need. The first question that comes to our mind when buying a LED light bulb is that; Is it enough to light...
There are two different methods for producing white light with LEDs. The first of these is the RGB method and the other is the phosphor method. The most commonly used option in the lighting industry is the phosphor method. In the phosphor method, a blue LED chip is coated with...
Thinking of upgrading your lighting? Don’t do anything until you’ve checked out the 10 mistakes that most people make with new LED lighting.
Color is one of the principal elements of design and also one of the easiest way to transform a space. The appearance of paint colors continuously changes according to daylight during the day and artificial light characteristics in the evening. As users, we experience the effects of light in our...
People of the modern era spend most of their time in built environments, such as offices, schools, shopping malls, restaurants, showrooms. The physical properties of these indoor spaces have various effects on the users. The most important of these features is lighting.
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.
A light bulb we use at home everyday emits about one quintillion photons per second and hundreds of billions of photons included in the light are coming into our eyes. The light energy delivered to the eye plays a key role in maintaining normal biological activities including visual perception, circadian...
The performance of white LED’s can be improved, based on better knowledge of the absorption and scattering of light inside the LED. A new method, developed by the University of Twente in Netherlands and Philips Lighting, can lead to efficiency improvement and powerful design tools.
University of Arizona has studied the effects of LED light therapy, and taken a step forward towards the potential use of light as a treatment for some forms of chronic pain, by studing the impact of visible-spectrum light from LEDs on the sensory thresholds in rats. Researchers have also studied...
