Every space we need to illuminate is unique. Choosing the right LED lighting color can be tough. It’s one of the most important factors when selecting your lighting fixtures and will make a big difference in how successful your project ends up being. In 1931 the CIE published its famous Chromaticity graph. It meant that every color that could be created by a mixture of red-green-blue could be given a unique number on the graph. Around 1940, David MacAdam ran a series of tests and demonstrated that rather than a single color is indicated by a point on a graph,...
In view of the increasing demand for lighting, the requirements for the light color quality of LED lamps in the application market are becoming more and more stringent, and the requirements for the color tolerance of LED lamps are also higher. Because it is difficult for people to intuitively understand color coordinates and DUV indicators, they are more accustomed to using human eyes to evaluate the difference in light color between LED lamps. The human eye evaluates the color difference is very subjective, and it also considers that the control of the color difference of the lamps will increase the...
Outdoor waterproof LED lighting fixtures need to withstand the scorching sun, wind, rain, thunder, and lightning for a long time, and the cost is relatively high. Because it is difficult to dismantle and repair the exterior wall, it must meet the requirements of long-term stable work. The LED is a delicate semiconductor component. If it gets wet, the chip will absorb moisture and damage the LED, PCB, and other components. Therefore, the LED is suitable for working in dry and low temperatures. To ensure the long-term stable operation of LEDs in harsh outdoor conditions, the waterproof structure design of lamps...
There are various kinds of plastic materials, and some are widely used for LED lighting fixtures, such as PC, PMMA, PS, etc. But do you know what’s the difference between them? Let’s have a look here. 1. PC(Polycarbonate) PC, scientific name polycarbonate, this material has a slightly lower light transmittance than PMMA, the penetration rate is about 89% at 3MM thickness, but it is higher temperature resistant than PMMA, the heat distortion temperature is 135 degrees centigrade, and it is resistant to yellowing, so outdoor lamps are often using PC lens, and when it is used as anti-glare microstructure board,...
After more than ten years of development, the LED lighting industry has risen from the pursuit of light efficiency, energy-saving, and cost to the demand for light quality, health, biosecurity, and a light environment. Especially in recent years, the problems of blue light hazards caused by LEDs, human rhythm disorders, and human eye retina damage have gradually become apparent, making the industry aware of the popularity of healthy lighting. However, the light color is soft, the color temperature is suitable, no radiation, no flicker, less blue light, high color rendering, and natural light, is it healthy lighting if meeting the...
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...
