What are Dimming Curves and How to Choose?

In specification of LED drivers or dimmers we usually see a keyword “Dimming curves”. That means how LED drivers set electrical parameter output in response to control signal input. Actually, the driver translates that signal to an electrical current that powers the LED. And then we can perceive the light brightness from the lamp. To […]

LED Drivers Technical Glossary

AC Input Voltage – The nominal range on the power supply label as approved by the safety agency is always 10% less than the usable input voltage range. For example, a switching power supply with a nominal 100 to 240VAC has an actual range of 90 to 264VAC. Our datasheet shows the usable voltage range; the label […]

Power Factor Correction Basics

1.1 What is Power Factor? Power factor (pf) is defined as the ratio of the real power (P) to apparent power (S), or the cosine (for pure sine wave for both current and voltage) that represents the phase angle between the current and voltage waveforms (see Figure 1). The power factor can vary between 0 […]

The Difference between DALI Device Type 8 and Type 6

1. DALI History Digital Addressable Lighting Interface (DALI) is a protocol for digital lighting control that enables the easy installation of robust, scalable and flexible lighting networks. Today DALI is the most common used digital protocol for light. And DALI protocol is maintained by Digital Illumination Interface Alliance (DiiA), a global consortium of lighting companies […]
