The working principle of triac dimming is to cut the input voltage waveform through the conduction angle to produce a tangential output voltage waveform. Using the principle of tangential direction, the effective value of the output voltage can be reduced, thereby reducing the power of the ordinary load (resistive load). The advantages of triac dimming are higher working efficiency and stable...

Smarts are develop more and more dimmable & non dimmable type led driver. Here release new products: highly compatible constant 277vac triac dimming power supply.   Let’s take a look at the other features of this new dimming power supply.   1. Leading edge and trailing edge dimming   2. The new constant voltage triac dimming power supply 3.0 ve...

With the progress of LED technology, there are many dimming modes for LED illumination, Triac dimmable LED driver is one of them. Compared with other dimming modes,Triac dimmable LED driver has its special advantages and disadvantages. The common incandescent, halogen lamps are often controlled by Triac dimming LED driver. They has no requirement on the input voltage, just...

There are different opinions on how LED lighting fixtures can be equipped with lighting control systems. The most critical part is to choose a dimming power supply. Different environments and needs, the dimming method is different, which is the common point of each dimming project. For example, the project did not have a dimming effect at the beginning, but a dimming function was needed in later p...

Using a triac dimmer connect to the input of “N” of the triac dimmable led driver for dim the LED lamp. During the conduction process of the triac changing the voltage division ratio of the internal adjustable resistor and changing its conduction angle, the effective value of the output voltage can be changed to achieve dimming function. In addition to triac dimming mode, there are leading edge an...

In the next two years, the smart dimming of Dimming LED Power Supply, especially in commercial lighting, will be expected to increase rapidly. Cause, with the rise of the global LED commercial lighting market, many LED manufacturers including China have placed LED commercial lighting products at an important position in market development. In particular, due to recent high-efficiency, long-life, h...

All mains-powered light sources flicker – whether halogen, fluorescent incandescent, or LEDs. In the UK, mains electricity is an alternating current (AC) power supply, delivered at a frequency of 50 hertz. Which means the electric current that powers your lights – any lights – switches backwards and forwards 50 times each second. We didn’t used to notice it with our old incandescent...

Smarts Electronics 2018 Hong Kong International Lighting Fair Organized by the Hong Kong Trade Development Council(HKTDC), Hong Kong International Lighting Fair had kicked off on 30 October at Hong Kong Convention and Exhibition Center(HKCEC). As Asia’s largest Autumn Lighting Fair, Hong Kong International Lighting Fair attracted lots of customers from all around the world. Let’s review Smarts Ele...

Both constant current and constant voltage LEDs and drivers can be made with a dimming capability. Dimmable external drivers often require an external dimmer, or other dimming control devices specified on the product datasheet (namely TRIAC, Trailing Edge, or 1-10v dimmers) to work. Smarts Electronics offers Triac Dimmable LED Driver, 0-10v led driver and Dali Dimmable LED Driver. Here I would lik...

Recently, Smarts Electronics issued a new series Triac LED Driver which are UL Listed, Type HL, Class P standard and 7 years warranty. New Multi-Dim Regulated Dimmable 12Watt 20 Watt Class 2 constant voltage 12VDC/ 24VDC LED Driver features outstanding LED dimming performance that use Pulse-Width Modulation (PWM) dimming for smooth dimming.Ccompatible with wide range of dimmers.   Compatible ...
