Vantablack is a super black coating developed in 2014 by Surrey NanoSystems, a British company. The materials to which this coating is applied absorb 99.965 percent of light. This makes it the blackest known man-made coating.
In the past, perhaps few would have predicted that LEDs in watch displays would be the lighting technology of the future. But it has happened and LEDs are now being used for general lighting purposes. Could OLEDs or laser diodes replace LED technology? And what about light-emitting plants?
Light travels much faster than sound. One of the most classic examples is lightning. When lightning strikes, the first thing you see is a flash of lightning in the sky, while the sound of thunder is heard a few seconds later.
Polymethyl methacrylate (PMMA) is a transparent and rigid thermoplastic material. PMMA is also known as acrylic, acrylic glass and plexiglass. It is widely used in the production of lenses, diffusers and light guides in the lighting industry, as it provides high light transmittance.
LDR (photoresistor) and photodiode are two types of light sensors commonly used. When the LDR is exposed to light, its resistance changes. The photodiode, on the other hand, produces current when exposed to light. This is the main difference between LDR and photodiode.
Light consists of small packets of energy called photons. Light energy is a form of electromagnetic radiation and is the only form of energy visible to the human eye. Light energy travels in waves and is very fast. The sun, stars, lamps, lasers, and hot objects are examples of light...
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...
Light bulbs are generally rated in two different classes, warm white and cool white. Generally, warm white indicates 2700-3000K color temperature range, while cool white represents 6000K-6500K color temperature. Which one should we choose for our houses?
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.
Light is a phenomenon that allows living things to see as a result of a beam hitting objects or reflecting directly after it leaves the light source. Light refers to visible light with its widespread use. Objects that emit light on their own are called light sources.
Amsterdam light festival gives visitors a dazzling experience on long winter nights. Residents and thousands of tourists can enjoy through the canals at night, these light-based artworks.
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...
Since the concept of LED lighting has entered our lives, we have started to learn very different terms. One of them is the "full spectrum". Some manufacturers state that their LED lighting products emit full spectrum light. So, what is full spectrum?
