How to use LED dimmable driver in dimming details

LED dimmable driver is one of widely used products in the market. Many people just know the product function, but don’t know how to use LED dimmable driver in dimming details.

a.    Adopting Direct current LED dimming driver technology

It is very easy if you want to change LED brightness. First, you should change the current of LED driver. Because led brightness is proportional to the current of LED driver.

b.    Adjusting the forward current, the phosphors will remove

There is a problem that adjusting the forward current will change LED driver’s chromatographic and color temperature. Because nowadays white lighting is produced by LED drives yellow phosphors. When the forward current reduces, blue lighting brightness is stronger. However, the thinness of yellow phosphors doesn’t decrease.  The main wavelength is longer than before.

c.    Adjusting the forward current, you can not control LED dimmable driver correctly

Because the forward current is not completely proportional to light output. Different LED has different forward current and light output. So it is not easy to control the light control.

d.    The constant current LED driver will not work well if you adjust the current

It is well-known that LED usually drivers constant current drivers. This kind of constant current drivers are divided into high current and low current.
