Problems solved by technology

The existing LED power supply will choose a controller to control the LED luminous effect while supplying power to the LED, but the existing controller will keep a certain distance from the power supply, and then supply power separately, because too close will cause Interference affects the normal operation of the equipment, which requires more space and correspondingly higher costs

Embodiment Construction

[0048] Below in conjunction with specific embodiment and accompanying drawing, the invention is further elaborated and illustrated:

[0049] Please refer to figure 1 , a method for eliminating signal interference inside an LED power supply with a control module, used to eliminate signal interference between the internal control module and the power supply module of the LED power supply.

[0050] The microprocessor inside the control module collects the electrical signal output by the power module;

[0051] The microprocessor converts the collected electrical signal output by the power module from an analog signal to a digital signal;

[0052] The microprocessor performs frequency comparison between the converted digital signal and the set signal;

[0053] The frequency of the digital signal is within the frequency range of the set signal, and the microprocessor converts the digital signal into an analog signal for output;

[0054] When the frequency of the digital signal ex...

Abstract

The invention discloses a method for eliminating the internal signal interference of an LED power supply with a control module, which is used for eliminating the signal interference between the internal control module of the LED power supply and the power supply module, and the microprocessor collects the electrical signal output by the power supply module Convert from analog signal to digital signal; the microprocessor compares the frequency of the converted digital signal with the set signal; the frequency of the digital signal is within the frequency range of the set signal, and the microprocessor converts the digital signal into an analog signal for output ; When the frequency of the digital signal exceeds the frequency range of the set signal, the microprocessor stops and processes it. If the digital signal still exceeds the frequency range of the set signal after multiple processing, the microprocessor stops the output of the signal and removes it. The invention shortens the combination distance of the control module and the power module by eliminating the signal interference between the internal control module and the power module of the LED power supply, saves equipment space and facilitates installation.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED power supply with a control module and a method for eliminating internal signal interference of the LED power supply with the control module. Background technique [0002] With the development of science and technology, more and more technological products have entered people's lives, and technological products cannot be separated from the power supply, which can provide sufficient power for technological products to maintain their work. The existing LED power supply will choose a controller to selectively control the LED luminous effect while supplying power to the LED, but the existing controller will keep a certain distance from the power supply, and then supply power separately, because too close will cause Interference affects the normal operation of the equipment, which requires more space and correspondingly higher costs. Contents of the invention [0003] The objec...
