Multipurpose intelligent controller of LED lamp

Abstract

The invention discloses a multipurpose intelligent controller of an LED lamp. The multipurpose intelligent controller comprises a single chip microcomputer, wherein the single chip microcomputer is a PIC16F883 chip which is internally provided with an EEPROM unit and externally provided with a digital-to-analog converter, a PWM output and a USART module, and a temperature collection module, a voltage and current collection module, an environment illumination collection module, an infrared remote control module and a manual input control module are respectively connected to the digital-to-analog converter. The PWM output is connected with an LED driving power source, the output end of the LED driving power source is connected with an LED lamp set, a wireless communication module is connected to the USART module, and the EEPROM unit of the single chip microcomputer is used for programming to set three application modes of the LED lamp, namely, an indoor illumination mode, a village street lamp mode and an urban street lamp mode. A mode selection switch is connected to the single chip microcomputer to select the application modes of the LED lamp, and a clock control unit is connected to the single chip microcomputer. According to the controller, multifunctional intelligent control over the LED lamp can be achieved.

Description

technical field [0001] The present invention relates to the field of LED lighting technology and intelligent control, and specifically relates to a multi-purpose intelligent controller that can be used for urban and rural LED street lamps and indoor LED lighting. Background technique [0002] As a new generation of light source, LED has many advantages that traditional light sources cannot match, such as high luminous efficiency, low power consumption, long life, pure light color, high stability, strong safety, environmental protection, and anti-vibration. Environmentally friendly lighting technology, under the background of energy saving and emission reduction, LED lights have received great attention in recent years and have been put into practical applications in large quantities. At present, LED lamps generally have the following limitations: [0003] 1. LED functional lighting fixtures all use high-power lamp beads, and most LED lighting fixtures only achieve simple l...

AI Technical Summary

Problems solved by technology

[0003] 1. LED functional lighting fixtures all use high-power lamp beads, and most LED lighting fixtures only achieve simple lighting effects, without intelligent management of LED lighting fixtures. No matter how much light intensity is required for road lighting, They all emit light uniformly according to the same brightness.

[0004] 2. Managers cannot monitor the operating status of LED lamps in real time, and they must rely on people to go to the site where the lamps are used to know the operating status of the lamps. The management cost is relatively high

[0005] 3. LED lamps are limited by the use environment and cannot take into account the needs of rural, urban street lamps and indoor lighting at the same time

The service life of electrolytic capacitors is mainly affected by temperature. Generally, every time the temperature rises by 10 degrees Celsius, the service life will be reduced by about half, which greatly limits the service life of the LED lamp drive power supply, which in turn affects the service life of the entire LED lamp.
