What is PWM dimmer?
17 Dec, 2020
LEDs can be dimmed in two ways: analog and pulse-width modulation (PWM) dimming. PWM dimming has a frequency and a duty cycle. PWM dimming works by turning the LED on and off at a very high speed. The frequency determines the number of pulses per second of the LED, and the duty cycle determines the duration of the pulses. For the frequency happens so fast, human beings perceive a lower bright...

How many kinds of Dimming type?
22 Dec, 2020
If you are not familiar with the dimming types that are compatible with LEDs: following details will definitely help you. Mains / phase cut dimming As the power of phase cut dimming led driver is reduced in some way therefore less power reach into LED light and becomes dims. This dimming led power supply uses standard L, N，G wires, easy to install and...

Eight tips to improve the efficiency of LED power supply
05 Jan, 2021
1. The main current loop PCB should be as short as possible. LAYPCB experience, and layout, this is nothing, the quick way is to look at the works of big factories. 2. Optimize the design of 300w LED transformer parameters to reduce eddy current loss caused by ringing. This is more difficult. First, you must master the basic knowledge...

The Lifetime and Reliability of led driver vs power supply
01 Feb, 2021
The LED is a device that includes a single PN junction and has conductivity on one side. The LED will only emit light when current is applied forward. Because LED lights work at low voltage, the led screen power supply needs to properly manage the load and effectively provide the required low voltage power to the LED. The street light power supply rectifies commercial AC power into DC po...

Choose LED Power Supply or power adapter?
24 Feb, 2021
Both LED power supply and power adapter are widely used for driving LED strip light. How to choose the suitable one? Depend on the project scale and installation way. Many users intend to find a led strip driver for 5m or 10m LED strips. Here we have to explain that it is not the LED strip length that determines what led power supply driver to choose, however is the total wattage of the LED...
