7 Frequently Asked Questions About DALI Dimming

7 Frequently Asked Questions About DALI Dimming DALI is a special lighting control protocol, with overall dimming, group dimming, address dimming, multi-scene mode settings, with simple and reliable, excellent functions, flexible expansion, and other characteristics. When replacing a new device, this new DALI device automatically obtains the address of the original old device. If two or more devices are replaced, the new device will get any of the free address. Therefore, when the device is installed, there will be no duplicate...

What’s Beam Angle for LED Lighting Fixtures?

What's Beam Angle for LED Lighting Fixtures? The beam angle is something that needs to be taken care of in selecting the appropriate LED lighting for space. The definition of beam angle is different for organizations in different regions, which makes it is more confusing. It is because that it is usually not easy to accurately determine the boundary of the light beam, so make a regulation artificially, specifying an edge, the light outside the edge has been weakened to be...

What’s Emergency Lighting

What's Emergency Lighting The LED industry has entered a mature stage, and general lighting technology has become transparent, entering the competition of scale and quality control. In recent years, the improvement of safety awareness has made users pay more attention to the application of emergency lighting, and emergency power supply, as the core of emergency lighting, plays a key role. But at present, users do not understand emergency power supply. Isn't it just a power supply with a battery? Not so, the...

Do LEDs Lighting Fixtures Change Colour Over Time?

Do LEDs Lighting Fixtures Change Colour Over Time? Most light sources will degrade over time and the LED is no exception. The electrical and thermal stresses on the components will have an effect on the colour performance eventually. Color shift is a mode of early LED failure occurs. Color shift involves a significant change in the spectral output of a light source, resulting in a change in the color temperature and colour rendering properties. Color shift can occur temporarily due to operating conditions or permanently as a result of...

SDCM & MacAdam Ellipse and Why Are They Important for LED Lighting Fixtures?

SDCM & MacAdam Ellipse and Why Are They Important for LED Lighting Fixtures? 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, it could be represented by an ellipse surrounding that point. Within...

What Factors That Affecting The SDCM of LED Lighting Fixtures

What Factors That Affecting The SDCM of LED Lighting Fixtures 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...

How to Make an Outdoor LED Lighting Fixture Waterproofing

How to Make an Outdoor LED Lighting Fixture Waterproofing Outdoor 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...

All You Need to Know About UGR

All You Need to Know About UGR UGR stands for Unified Glare Rating. Uncomfortable glare in industrial lighting and common rooms or places in public buildings should be evaluated using the unified glare value (UGR). The lower the value, the less discomfort the user will experience from the lighting. For lamps with a large luminous surface such as panel lights, linear lights should be implemented with plates that can suppress large-angle light. The above method can also be used for lamps with a...

Plastic Materials: What’s the Difference Between PC, PMMA, and PS?

Plastic Materials: What's the Difference Between PC, PMMA, and PS? 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...

What’s Healthy Lighting? Here Are Some Details You Must Know

What's Healthy Lighting? Here Are Some Details You Must Know 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 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...
