Blue light is a type of electromagnetic radiation that is found throughout the visible spectrum. With the advancement of science and technology and the development of society, electronic products, such as computers and mobile phones, have become necessities in people’s lives. The ubiquitous electronic screen is full of our lives, studies, and work. However, the high-energy light emitted by electronic products is constantly impairing people’s vision health. So, what is blue light? Maybe it sounds familiar to you, but we are unfamiliar if checking in detail. The light that the human retina can perceive is visible light, and the wavelength...
Natural light full-spectrum LED is coming into a new development trend in lighting Comfortable and healthy lighting has become a new demand for consumption. So what kind of light source is a comfortable and healthy light source? Human beings have lived on the earth for millions of years and are constantly evolving with changes in the living environment, but the only constant is dependence and adaptation to sunlight. Therefore, it can be considered that natural light or sunlight is the most comfortable and healthy light source for human beings. LED sunlight is a revolutionary new technology that uses light-emitting diodes...
The Importance of EMC As early as the early 1980s, infant mortality was quite high in the maternity ward area of a hospital in New Jersey. Late at night, the warning light on the baby’s monitor always goes out for no reason. The nurses were so annoyed that they turned off the monitors and went back and forth one by one. After a preliminary investigation, the professor ascertained the truth of the matter. It turned out that the transmitter of a nearby television station was approved by the American Communications Commission and its output power can be increased quite high...
Smart LED lighting control systems have enabled energy conservation and increased energy efficiency in offices, buildings, theatres, and various other places. LED lighting controls like DMX and DALI are some such variants that are very popular among others. They use automated dimming controls to conserve energy. To compare DMX and DALI LED lighting controls, you must know about each of these luminaries’ commands. Upon learning the working and functionality of each of these controls, you will be able to make out the difference easily. DALI LED Lighting Controls In the DALI LED lighting controls system, more than one control panel...
A lighting system based on the DMX light control protocol for dimming control is called a digital lighting system. At present, various stage lighting equipment, including stage lights, dimming controllers, consoles, color changers, electric booms, and other stage lighting equipment, including computer lights, have fully realized the digitalization of the dimming system, and based on this, it gradually becomes computerized and networked. Therefore, for film and television lighting design and operators, it is necessary to understand the program structure, control principles, and application points of the DMX512 control protocol. 1. DMX512 lighting control protocol DMX is the abbreviation of Digital...
Dimmable LED lights are great for creating mood lighting – whether you’re having a romantic night, watching a movie, or even playing your favorite video game. You can use several different dimming options to dim LED Lighting. Currently, the most commonly used LED dimming systems are: LED TRIAC dimming, LED 0 / 1-10V dimming, PWM dimming, DALI, etc. Other dimming works by controlling the output of current, voltage, and frequency to achieve the LED dimming function. Please see the detailed introduction of various dimming methods below. Phase – Triac Dimming LED Lightings Triac dimming has been applied to incandescent and...

LED technology started in the semiconductor industry, but is booming in the lighting industry. As a newborn thing, it is facing many questions and discoveries. LED is famous for its extra-long lifespan. However, how we can predict the lifespan of LED without any convincing tests? Is there any difference in the lifespan of LED with the traditional lighting source? Comparing LED with traditional lighting and analyzing the latest standard development meanwhile, hope it will help you understand what the lifetime stands for really. 1. LED development background The life of traditional light sources is mainly determined by the life of...
It is often heard that the short life of LED lamps is mainly due to the short life of the power supply, and the short life of the power supply is due to the short life of the electrolytic capacitor. These claims could make sense. As the market is flooded with a large number of short-lived and inferior electrolytic capacitors, coupled with competing prices, some LED lighting manufacturers use these inferior short-life electrolytic capacitors regardless of quality. So what exactly is the actual situation? 1. The life of the electrolytic capacitor depends on the ambient temperature when it works How...
