LED lighting lamps and lanterns of the adjustable light efficiency can be is depends on the collocation of LED light source and drive power supply.
In general, the LED light source can be simply divided into two broad categories: LED diode light alone or with a resistance of LED diode light source, on application, sometimes LED light source is designed to contain DC -
A DC converter modules, such a complex modules are not within the scope of this article.
If the LED light source or module for single LED, LED dimming methods common to adjust the amplitude of input current in leds, so the selection of LED drive power supply should refer to this feature, and by the external 1 -
VDC 10 * 10 v PWM pulse width modulation or even only through an external a simple variable resistance to control the output current of the modulation.
While another is equipped with a resistor LED diode light source (
Commonly referred to as article LED lamp or LED STRIP)
, article LED lights are widely used have LED diode series resistance, so the voltage are relatively stable, so users can access any sold the rated voltage of power supply to drive the leds.
Common article LED lights are typically 12 VDC or 24 VDC driver, but also so in the article LED lights dimming applications can be a bit difficult.
This paper illustrates the use current amplitude adjustable light way of the application of drive in the article LED lights, also discuss some common problems that move light, and introduced the output pulse width (at the same time
Modulation of the adjustable light LED power driver.
