LED driving power supply and control method thereof, lamp and computer readable storage medium

Abstract

The invention provides an LED driving power supply and a control method thereof, a lamp and a computer readable storage medium. The control method comprises the steps of acquiring and storing settingparameters, wherein the setting parameters comprise a preset current value and a preset voltage value, outputting a first control instruction according to the set parameters, and obtaining an actual current value and an actual voltage value, comparing the actual current value with a preset current value, comparing the actual voltage value with a preset voltage value, and outputting a second control instruction according to a comparison result if the actual current value is inconsistent with the preset current value and/or the actual voltage value is inconsistent with the preset voltage value until the actual current value is consistent with the preset current value and the actual voltage value is consistent with the preset voltage value. The invention further provides an LED driving powersupply, a lamp and a computer readable storage medium which apply the control method. According to the control method of the LED driving power supply, current parameters and voltage parameters meetingthe use requirements of the LED load can be provided for the LED load.

Description

technical field [0001] The present invention relates to the technical field of lamps, in particular to a method for controlling an LED driving power supply, an LED driving power supply using the above-mentioned control method, a lamp provided with the above-mentioned LED driving power supply, and a computer-readable storage medium for realizing the above-mentioned control method . Background technique [0002] At present, LED lamps gradually replace traditional tungsten lamps, fluorescent lamps, incandescent lamps and other lamps and become the mainstream lighting lamps, which makes more and more types and specifications of LEDs. However, LED lamps of different types or specifications need to be equipped with different LEDs. The driving power supply can make the LED lamps work safely and reliably, and make the LED lamps have a long service life. [0003] However, the vast majority of LED drivers currently on the market can only output voltage and current values ​​of one spe...

Problems solved by technology

[0003] However, the vast majority of LED drivers currently on the market can only output voltage and current values ​​of one specification parameter, while relatively high-end smart LED drivers can adjust the output in four gears or The eight-position adjustment output is performed through the three-position DIP switch, but no matter how many digits the DIP switch has, its adjustment output is always limited, and it cannot accurately and reliably provide very suitable current parameters for a variety of different LED loads. And voltage parameters to ensure the reliability, safety and long life of LED lamps
