Abstract

The application relates to an LED light source control device, a method, a light source component and a photoelectric pulse detection device. The LED light source control device is used for controlling the LED light source, and the LED light source includes a plurality of LED lamps. The LED light source control device includes multiple constant current drive modules and control modules. A plurality of constant current driving modules are respectively electrically connected to a plurality of LED lamps for driving a plurality of LED lamps. The control module includes a uniformity processing module and a current control module. The uniformity processing module is electrically connected to the current control module, and the current control module is electrically connected to multiple constant current drive modules respectively. The uniformity processing module is used to receive the uniformity parameters of the LED light source, and determine the driving current adjustment scheme for multiple LED lamps according to the uniformity parameters. The current control module is used for adjusting the driving current of multiple LED lamps according to the driving current adjustment scheme. The LED light source control device of the present application can improve the uniformity of the LED light source.

Description

technical field [0001] The present application relates to the field of LEDs, in particular to an LED light source control device, method, light source assembly and photoelectric pulse detection device. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) is a semiconductor electronic component that can convert electrical energy into light energy. With the continuous advancement of technology, LEDs have been widely used in monitors, televisions, lighting decoration and lighting.
