The advantages of LED are gradually revealed, and LED has been widely used in the LCD backlight of mobile phones for several years. Today, its applications include GPS, Portable LCD and even large area of car navigation. LEDs are […]
Where is the core of LED lighting power design
In the design of LED lighting power supply, there are several design problems: the life of electrolytic capacitor does not match with LED, the common causes and treatment methods of LED flicker, the influence of PWM dimming on LED life, and the potential problems of adjusting LED brightness by triac dimming. Zheng Zongqian, senior application […]
What is the isolation and non isolation of driving power supply
At present, in the general LED lighting market, there are two types of non isolated design and isolated driving power supply. The non isolated design is limited to dual insulated products, such as alternative products for light bulbs, where the LED and the entire product are integrated and sealed in a non-conductive plastic, so there […]
How to realize the ideal driving of LED driver
LED is a kind of semiconductor device that emits incoherent narrow spectrum light when it is biased forward and produces an electroluminescence phenomenon. In other words, solid phosphors convert electrical energy directly into light under the action of an electric field. The color of the luminescence depends on the chemical composition of the semiconductor material […]
