In the lighting industry, there are some signs that provide information about the reliability, efficiency and quality of the product. In lighting devices; UL, cUL and DLC are frequently encountered abbreviations. So, what do all these abbreviations mean?
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?
Blue light alone does not have a whitening effect. The purpose of the blue light is to speed up the teeth whitening process. It should be used with a bleaching solution. The combination of chemical and blue light significantly increases the final whiteness level of the teeth.
A solar charge controller is a type of regulator that transfers the energy from solar panels to the batteries and load. The charge controller is used to charge the batteries with the electrical energy obtained from solar energy. The charging voltage is regulated to suit the batteries and the batteries...
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.
An oscillator is an electronic circuit or device that can convert a steady-state signal into an oscillating signal (sine wave signal). Oscillators are used to generate repetitive electronic signals. An oscillator can convert a steady-state DC signal into a periodic AC signal at a desired frequency.
When you heat something, you notice that its temperature rises. This may make you think that heat and temperature are the same thing. Because of this misconception, heat and temperature are often used interchangeably. Although the two concepts are related, they are not the same. It is therefore very important...
LED street lights are modern lighting devices used to illuminate roads, streets and alleys. LED luminaires have a different and more complex structure than traditional luminaires. Are you wondering what is included in an LED street light?
Calibration is a documented comparison of a measuring device to a traceable reference device. Calibration refers to the process that enables measuring instruments to produce outputs that provide high levels of accuracy and precision. The main purpose of calibration is to ensure the accuracy of measuring instruments and to minimize...
More and more consumers are meeting with LED lighting every day. LEDs are highly efficient and long-lasting light sources. LED lights must meet certain criteria to operate safely during their specified lifetime. Testing LED lamps and fixtures before they are released enables consumers to purchase high-quality products.
Every living thing needs energy to grow. Humans get their energy from food. Plants, on the other hand, get energy from light in a process called photosynthesis. Light initiates the growth cycle of the plant and supports its healthy development. Blue light is essential for the first stage of plant...
LED lighting devices experience significant energy loss during AC-DC power conversion, electro-optical conversion (electroluminescence), and wavelength conversion. Unlike conventional technologies, in LEDs, all energy losses in the light emitting process are expelled as heat. This presents a major engineering challenge where more than half of the power input is converted...
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.
PAR is an abbreviation formed from the initials of the words Parabolic aluminized reflector. PAR lamp is a type of lamp widely used in commercial buildings, residences and transportation vehicles. PAR lamps are used in the headlights of old vehicles, exterior lights of vehicles such as trains and airplanes, and...
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...
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.
