The dimming curve is one of the parameters of the dimming device, it directly affects the effect of the important output output, and it is the performance of the digital dimming device.

LED dimming lighting circuit is composed of dimmer or controller, driver and lamps. To dim the light, move the drive or control the dimmer to send a signal to the dimming led drive. The signal is converted into the current supplied by the LED to adjust the power.

In linear adjustment, the position of the driver's signal of the dimmer relative to the position of the dimmer, if the position of the dimmer is linear, then it can reach 25% of its position. The signal to the driver will also be at 25%

Because the human eye's sensitive area to light is below 25%. This means: there is a difference between the actual light intensity we measure and the light intensity we perceive

In order to achieve perceptible linear dimming, the brightness of the LED must match the perception behavior of our eyes. For linear dimmers, a logarithmic dimming curve should be used in the driver. For logarithmic dimmers, drivers with linear dimming curves should be used
