How LED Lights Are Affected by Heat

How LED Lights Are Affected by Heat Compared with incandescent lamps and fluorescent lamps, LED has the advantages of high light efficiency, long life, fast response, and environmental protection. LEDs are cool to the touch because they don’t usually generate heat in the form of infrared radiation such as that given off by the sun, heating coils, or incandescent lamps. That makes them perfect choices for places where heat creates problems. But it’s not true that they don’t produce any [...]

Dimming Singals: Analog Dimming and Digital Dimming

Dimming Singals: Analog Dimming and Digital Dimming There are different methods for dimming, but do you know which kind of dimming signal before you buy a smart LED lighting fixture with dimming systems? The dimming signal can be divided into: analog dimming and digital dimming. Analog and Digital Dimming Singal 1. Analog dimming Analog dimming is to modulate the bias of the base of the transistor or the gate of the MOS tube according to the change of the corresponding load to achieve [...]

What Are Dimming Curves

What Are Dimming Curves The dimming curve is a parameter that the dimming device often enumerates. Generally speaking, a dimming device outputs light according to a predetermined function after receiving the input signal. This function image is the dimming curve. It is one of the important parameters of dimming equipment. It directly affects the effect of light output and is the embodiment of the performance of digital dimming equipment. Types of the dimming curve There are many dimming curves, and some devices [...]

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 [...]

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 [...]

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, [...]

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 [...]

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. [...]

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 [...]

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 [...]
