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.

Core Values of LED Dimmable Driver

As the main force of LED dimming products, LED dimmable driver has been widely accepted and recognized by users all around the world. Faced with fierce competition, LED dimmable driver manufactures should seriously consider the core values.
Compared with the traditional power supply, LED dimmable driver has strong function for dimming the lighting. The technology and performance have improved with the progress of time. The LED dimmable driver manufacturers can not only meet users requirement, not also continuously expand the resource of upstream suppliers. They go after the excellent quality, meanwhile don’t forget the customized services and boost the competitive advantages. So the manufactures should recognized the core values of LED dimmable driver.

a. Energy Conversation 

One of the real goals is that LED dimmable driver is an energy saving product. According the different current level, you can adjust the brightness by LED dimmable driver to really realize the energy conversation.

b. Multiple Protections

It is well known that LED dimmable driver determines how long LED lamps work. LED dimmable driver should adopt multiple protection to avoid the damage, such as over current protection, over load protection, over temperature protection, short current protection, over voltage protection, etc. Multiple protections are important when you use LED dimmable driver. 

C. Certificates

If the products are sold all around the world, LED dimmable driver should pass some certificates by legitimate authority.

Here, we just give you several suggestions about the core values of LED dimmable driver. With the rapid development of technology, the products updated quickly. LED dimmable driver should meet the needs of social development and get the proper development at the same time.

How to Face the Design Challenge of LED Dimmable Driver?

With the increased emphasis on energy problems, many countries use LED chips to replace traditional lighting source, which has become an obvious trend. LED illumination lamps don’t need to change its basic components, it can be used directly with a good business prospect. Form many traditional lamps, MR16 is a representative product. It is widely used in markets, homes, hospitals, etc. It is well known that MR16 has small dimension and needs use transformer with dimmer to dim the light, which gives design challenge for LED dimmable driver.

First, let’s see a representative MR16 dimming system as below.

High voltage 220V transforms low voltage 12V via the transformer, which gives power to LED dimmable driver. We must fully consider the technologies of LED dimmable driver: dimming compatibility, dimension, cost, etc.

Euchips Launched New, Cheaper LED Dimmable Driver

At long last, Shanghai Euchips launched new products 3-in-1 LED dimmable driver EUP75A-1H12V-1E1 & EUP75A-1H24V-1E1, Triac dimmable LED driver EUP75T-1H12V-0E1 & EUP75T-1H24V-0E1, DALI dimmable LED driver EUP75D-1H12V-0E1 & EUP75D-1H24V-0E1.

These new LED dimmable driver products doesn’t just look different, in addition, there are several same features: 

a.high efficiency

b. support short circuit and over load protection

c. dimming smoothly and no flicker

d. excellent quality

e. white housing, popular appearance, simple usage

f. The dimension is 210*57*34mm

As you can see in the images below, the latest appearance design, strong functions, smooth dimming curve, no flicker, you will love them.

3-in-1 LED dimmable driver EUP75A-1H12V-1E1 & EUP75A-1H24V-1E1 support 1-10V active signal, adjustable resistance, PWM dimming and be suitable for indoor LED lighting application. 100% output when there is no dimming signal input, it can be used as normal power supply.

Triac LED dimmable driver EUP75T-1H12V-0E1 & EUP75T-1H24V-0E1 supports trailing edge and leading edge dimming, signal-channel constant voltage output, 3.1A or 6.2A Max. The dimming range is from 40VAC to 240VAC.  LED dimmable driver EUP75T-1H12V-0E1 & EUP75T-1H24V-0E1 have short circuit protection(Close the output, restart to recover since fault condition is removed for 10s) and over load protection(Limit the power to 110%~150~ of rated output power). 

DALI dimmable LED driver EUP75D-1H12V-0E1 & EUP75D-1H24V-0E1 meet DALI protocol IEC62386 and support Touch DIM function. The brightness adjustment range is 1%-100%, and the light can be turned off through short pressing when doing

the adjustment with long pressing Touch DIM switch.
