For 10% brightness under the 3rd driving current.So repeat, so as to realize the brightness regulation of the LED/light source to G9 LED bulbs.
Further, in control system default driving current setting order also not necessarily according to LED/light source
The order of brightness increment is set, and it can be set according to actual needs.For example, three drivings are preset in control system
Electric current, be respectively：First driving current, the second driving current and the 3rd driving current, it distinguishes the brightness of corresponding LED/light source
For 10%, 50% and 100%.When first switching on the switch of G9 LED bulbs, control system provides the first drive for LED/light source
The brightness of streaming current, i.e. LED/light source now is 10% brightness under the first driving current；Second of opening G9 after closing switch
During the switch of LED bulb, the driving current of LED/light source is replaced by the second driving current, now, LED/light source by control system
Brightness is 50% brightness under the second driving current；When the switch of G9 LED bulbs is opened after closing switch for the third time, control
The driving current of LED/light source is replaced by the 3rd driving current by system, now, and the brightness of LED/light source is under the 3rd driving current
100% brightness.
The brightness regulation of LED/light source is to be dependent on the requirement of client, also may be designed as n grades or within some period it is continuous
Light modulation.The change of light modulation can be designed as from most bright (100%) light modulation to minimum (1%) -- just as setting the sun, it is referred to as
For " sunset version "；The change of light modulation is also designed to from minimum (1%) light modulation to maximum (100%) -- just as sunrise,
Referred to as " day publication ".
