Have you ever felt that the lights in your room are too bright for your taste, or are you an environmentally enthusiastic person? I have a simple answer to your concerns, dimmable LED lights which brings a much more easy controlled lights than traditional ones like incandescent or fluerescent. You can use this technology to

All device components that come into contact with an electric current, such as LED drivers, must be isolated or protected. Do you want to know how you can do that? Well, it’s pretty simple! By the use of a Safety Extra Low Voltage (SELV) system, you can separate the electric circuit from other circuits carrying

If you’ve spent some time searching about how electric systems work in your daily life, you probably heard that there are two forms of electricity—alternating current (AC) and direct current (DC). They are both crucial for any electronics. However, people tend to get confused about their functions. That’s why in this article we will look

Light Emitting Diodes (LED) have gained prominence in the world of lighting. Its tremendous rise to the helm of lighting affairs due to its efficiency has seen it beat the competition from traditional lighting systems. The outstanding feat of LED drivers triggers curiosity, and people are asking the  question, “what is LED Driver Efficiency?” The

LED lighting penetrates everybody’s life, becoming more intelligent and more sophisticated. When designing high quality and excellent luminaire, the design engineer must carefully understand the LED Driver since it is the heart of a light fixture. This article describes the most frequently used LED driver concepts and provides the methods to select a suitable and

If you have compared different energy-saving light bulbs, you may have noticed that some are labeled as Energy Star products, while others carry the DLC label. Sometimes buyers are confused about the full content of these two energy-saving groups, and why some lamps have an approval mark for one group, but it seems that there

Table 1: V5.1 Efficacy Requirements for Luminaires and Retrofit Kits [DLC Standard and DLC Premium Classifications] Table 2: V5.1 Standard Efficacy Requirements for Lamps [In-Luminaire and Bare-Lamp]* Table 3: Testing and Reporting Requirements for Spectral Quality (DLC Standard) Table 4: Additional Testing and Reporting Requirements for Spectral Quality (DLC Premium) Table 5: V5.1 Testing and

What are the requirements onthe control line length of the DALI system? The length of the control line should meet the voltage drop requirements. The maximum voltage drop in the DALI system is 2V, relatively, the distance between the two farthest components in the system is 300m. For the terminal control system, the length of

The LED chip and driver are installed together, usually in small spaces and poor heat dissipation conditions. How to ensure the quality and life of the LED driver must be thought about before the design, so as to avoid the rapid failure of the LED driver. It can be said that the life of the
