Capacitors and supercapacitors are passive components that store energy in the form of an electrostatic field. Although the function of both is to store energy, there are some important differences between them. Supercapacitors can store more charge than regular capacitors and provide energy much faster than a battery.
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.
Devices that can measure the temperature of objects remotely and quickly without any contact are called infrared thermometers. Infrared thermometers collect infrared light emitted from objects and estimate their temperature based on the amount of energy. These devices are frequently used in industrial applications as well as preferred by home...
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.
In the lighting industry, lamps in which the brightness of the light can be controlled are called dimmable. Dimmable lamps make it possible to control the level of illumination, change the visual appearance of the space and save energy.
The Light + Building took place between October 2-6 this year, and the new calendar is 3-8 March 2024. It would be correct to say that this year was not good as the previous ones, as the number of exhibitors and visitors is much lower than last years.
Italian physicist Galileo Galilei made a simple experiment with the help of lanterns in 1638. He and a friend each took a lantern and drove miles apart. As soon as one of them signaled with the lantern, the other gave the signal to him. Galileo divided the distance between two...
In the development of LED technology, it was initially planned to produce a single type of LED, but over time it was realized that this was not a viable approach. With the technological developments, different types of LED packages have emerged. TH LED, Mid-power LED, High-power LED, COB (Chip-on-board) LED,...
Kinetic energy is the energy possessed by an object in motion. Potential energy, on the other hand, is the energy that an object has because of its position or state. This is the main difference between kinetic energy and potential energy.
Symmetrical lights distribute light equally in all directions. Asymmetrical lights concentrate the light in one direction. This is the main difference between symmetrical and asymmetrical lighting. In indoor and outdoor lighting applications, it is extremely important to choose the right light distribution and angle in order to minimize glare, improve...
Flux is a chemical used when soldering electronic components to a circuit board. The main purpose of flux is to prepare the surface for soldering by cleaning the oxide and foreign materials on the metal surfaces. Flux is used to clean the circuit board before soldering. During soldering, it helps...
Light + Building International Lighting and Building Services Technology Fair, which was not possible to take place in 2020 due to the pandemic, is opening its doors to its visitors again in Frankfurt between 2-6 October this year.
A photovoltaic cell, PV cell, solar cell, or solar cell is a component that produces electricity when exposed to light. The photovoltaic cell is made of semiconductor materials that absorb the rays emitted by the sun and generate an electric current. A solar panel is formed by bringing together more...
It is very important to position the lighting fixtures in order to illuminate the streets, roads and pavements correctly. No matter how bright lamps are used, the desired performance cannot be achieved if the lighting fixtures are not properly positioned.
Light measuring devices called lux meters can measure with high precision in a wide measuring range. But when it comes to LEDs things get a little more complicated. Different brands and models of lux meters may take different measurements at the same point.
There are two different application models, direct and indirect, for indoor and outdoor lighting. In direct lighting, the light is directed downwards, directly onto the surface to be illuminated. In indirect lighting, the light is directed upwards and reflected from the wall or ceiling.
There are some startling claims about LED lights, the latest and most efficient of lighting technologies. Misinterpretation of research in this area causes fears. Can LEDs really do that much harm to health?
In the lighting industry, LED refers to the LED package, not an LED chip. The LED package is a combination of one or more LED chips with mechanical supports, optical elements, electrical connections and thermal conduction paths. LED packaging is a critical process that affects the thermal performance, optical efficiency,...
The most common causes of LED failures are the use of poor quality LEDs, improper soldering of the LEDs, exposure to high temperatures, insufficient heatsink design, no current limitation in the power supply circuit, and problems with the battery.
Photocell and motion sensor are electronic devices used to manage indoor and outdoor lighting systems. These sensors are used to save energy by turning the lights on when it gets dark or when motion is detected, and turning them off when they are no longer needed.
