Optimize LED Illumination, How to Choose LED Dimmable Driver?

Nowadays, LED dimmable driver is divided into switching power supply and alternating direct LED driver. The design of switching power supply is complicated, the cost of solution is also high and the BOM number is large, includes magnetic components and electrolytic capacitors, which results in low reliability and short service life. However, the design of alternating direct LED dimmable driver is simple, the cost of solution is low, and BOM number is little, which doesn’t need electrolytic capacitors.
 Of course, switching power supply can exist with alternating direct LED dimmable driver. Switching power supply is suitable for end users. Magnetic components provides isolate function avoided the electric shock for users. In many commercial and industrial application, like down lamps, patio lamps, street lamps, etc., alternating direct LED dimmable driver solution is wonderful. Because of simple design, competitive price, small BOM number. In these applications, alternating direct LED dimmable driver is the best choice.
In our daily life, many users have some problems, like flicker. In order to solve flicker, it needs high PF and low THD performance. Luckily, alternating direct LED dimmable driver provides strong dimming function for intelligent illumination products, includes triac dimming, analog dimming and PWM dimming.
In a word, compared with switching power supply, alternating direct LED dimmable driver is more attractive for illumination manufacturers and widely accepted by users.
