Advantage of triac dimmable led drivers
19 Jun, 2020
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...

When Do I Need a “Constant-voltage” LED Driver?
25 Feb, 2019
Most commercially available LED “light modules” are constructed by connecting a number of LEDs in series orinparallel to form cluster or string configurations. In cases where these lights modules include a constant-current driver as part of the assembly, an external “constant-voltage” driver or power supply is required. Low cost LED circuits control the current flowing through the LED with a simpl...

What is a led driver
23 May, 2019
Due to increasing energy regulations, most people are familiar by now with the long life spans and energy savings associated with LEDs, or light-emitting diodes. However, many are not aware that these innovative light sources require specialized devices called LED drivers to operate. LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for lo...

Why do you need a driver for LED lights?
07 May, 2019
LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps). The two main types of LED drivers are Constant Voltage and Constant Current to power up the LEDs. Constant Volt...

What is PFC on led constant voltage power supply
23 May, 2019
Power factor is a factor that measures the efficiency of electrical equipment like led constant voltage power supply. The low power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is large, thereby reducing the utilization rate of the device and increasing the line power loss. By improving the power factor, the total current in the line and the ele...

What is the MTBF?
23 May, 2019
MTBF, that is "Mean Time Between Failure", It is a measure of the reliability of a product, especially for electrical product, the unit is "hour". MTBF reflects the time quality of the switching power supply and the ability to reflect that the led driver remains functional for a specified period of time. To be specific, it refers to the average working time between two adjacent...

How LED lighting works with lighting system
23 May, 2019
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...

Do you need a LED transformer for LED bulbs?
30 May, 2019
All LED bulbs require a 'driver' (a special type of transformer) to work properly. Mains voltage LEDs (such as GU10 and B22 bulbs) have the driver built in to the bulb. ... If you are replacing existing incandescent 12V bulbs you will need to replace the transformer with a special LED driver. Due to increasing energy regulations, most people are familiar by now with the long life spans and energy ...

Are your led driver flicker free?
06 Jun, 2019
Flicker can be defined as the perception of visual unsteadiness induced by a light source which fluctuates with time for a static observer in a static environment. LED Flicker is caused by voltage ripple at the output of the AC power supply. Furthermore, a stroboscopic effect is the change in motion perception induced by a light stimulus whose luminance or spectral distribution fluctuates with tim...
