Intelligent control device of light-emitting diode (LED) and intelligent LED lamp

Abstract

The invention discloses an intelligent control device of a light-emitting diode (LED). The intelligent control device comprises a pyroelectric infrared sensor for detecting infrared radiation emitted by a human body or a vehicle, a single chip microcomputer, a constant-current lighting adjusting drive power supply which switches on a switch power supply according to switch signals sent by the single chip microcomputer so as to supply constant working currents for the LED, a current sampling module collecting input currents of the constant-current lighting adjusting drive power supply, a voltage sampling module, an analog-digital converter, and a light adjusting controller which inputs light adjusting control signals to a light adjusting port of the constant-current lighting adjusting drive power supply according to the light adjusting signals provided by the single chip micro-computer. The intelligent control device adjusts luminance of the LED according to the environment where the LED is located, monitors according to operation parameters of the LED, and enables an administrator to understand the operation state of any LED lamp and conduct remote control on any LED lamp.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an intelligent LED control device and an intelligent LED lamp. Background technique [0002] As a new generation of light source, LED has many excellent properties. Because its principle is the energy of electron transition and hole recombination of PN junction, it emits light, so it is a solid-state light source. Coupled with efficient and stable phosphor technology, LED light source has high luminous efficiency. , low power consumption, long life, pure light color, high stability, strong safety, environmental protection, anti-vibration and many other incomparable advantages of traditional light sources. It is a green and environmentally friendly lighting technology. Against the background of the platoon, the advent of LED lighting is close at hand. [0003] At present, LED functional lighting lamps all use high-power lamp beads, and most LED lamps only achieve the effect ...

AI Technical Summary

Problems solved by technology

[0003] At present, LED functional lighting lamps all use high-power lamp beads, and most LED lamps only achieve the effect of simple lighting, without intelligent management of LED lamps, no matter how much light intensity is required for road lighting, They all emit light uniformly according to the same brightness.

Moreover, the manager cannot know the operating status of a certain LED lamp in real time at all. Only by going to the site where the lamp is used can the manager know the operating status of the lamp.
