Wireless driving system of light-emitting diode

Abstract

The invention discloses a wireless driving system of a light-emitting diode, which comprises an upper computer, a wireless communication module and at least one LED driving module, wherein each LED driving module is connected with an LED light source; the upper computer is used for transmitting dimming control signals to a specified LED driving module in a wireless form through the wireless communication module; the LED driving module comprises a singlechip which receives the dimming control signals and converts the signals into corresponding PWM wave forms, a current sampling unit which receives sample current fed back by the LED light source, and an LED driving power which adjusts driving current output to the LED light source based on the change of the PWM wave forms and the sample current; and the wireless communication module is used for realizing the wireless communication between the upper computer and the singlechip. By using the embodiment of the invention, the power of the LED light source can be driven in a wireless mode.

Description

technical field [0001] The invention relates to the technical field of light emitting diodes, in particular to a wireless driving system for light emitting diodes. Background technique [0002] At present, my country's power energy is relatively tight, and the stock of coal resources is limited. Many areas are prone to power supply shortages during peak periods of electricity consumption. Lighting power consumption accounts for 20% of my country's power consumption, so doing a good job in energy saving in lighting power consumption can effectively save power resources. [0003] LED (Light Emitting Diode, light emitting diode) is a semiconductor device that can directly convert electricity into visible light. LEDs were first used in the display of indicator lights, numbers and text. With the advent of white LEDs, LEDs have a low operating voltage. With the advantages of less power consumption, high luminous efficiency and long life, LED light sources are more and more wide...

AI Technical Summary

Problems solved by technology

In the existing LED wired drive power supply, a large number of metal cables need to be arranged, so that the arrangement of the LED light source has great limitations, inflexibility, poor scalability, and cumbersome maintenance

At the same time, the aging and scrapping of metal cables will pollute the environment and pose a considerable safety hazard to human life.
