Lamp control circuit and induction lamp

Abstract

The invention discloses a lamp control circuit and an induction lamp. The lamp control circuit comprises a PIR (Passive Infrared) interface module, a power supply module, an SCM (Single Chip Microcomputer), an LED (Light Emitting Diode) light source control module and an alarm control module, wherein the power supply module is used for supplying power for the PIR interface module, the SCM, the LED light source control module and the alarm control module, and the power supply module comprises a solar cell panel and a storage cell; the PIR interface module is connected with a PIR detector and is used for transmitting a trigger signal generated when the PIR detector is triggered to the SCM; the LED light source control module is used for controlling the lightening or the shutting of an LED light source; the alarm control module is used for controlling the starting or the shutting of an alarm; and the SCM is used for detecting output voltages of the solar cell panel and the storage cell, controlling the switching on or the switching off of the alarm control module and controlling the switching on or the switching off of the LED light source control module. According to the lamp control circuit and the inductance lamp, disclosed by the invention, the frequent alarm emitting in a time period with a larger visitor flow rate can be prevented, and the false triggering caused by a photoconductive resistor adopted by the traditional inductance lamp can be prevented.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a lamp control circuit and an induction lamp. Background technique [0002] A sensor lamp is a lamp that automatically lights up and turns off after a time delay when triggered. Traditional sensor lights have trigger forms such as sound control, light control and induction, and are mainly used for lighting and anti-theft. However, most of the traditional sensor lights only have lighting function, and the anti-theft effect is poor. In order to enhance the anti-theft effect, a small number of induction lamps are equipped with an alarm function, but usually the alarm is issued at the same time as the automatic lighting, and the lighting or alarm function cannot be used independently. Although it can provide lighting, it will also frequently send out unnecessary alarms. At the same time, photosensitive resistors are usually used to monitor light changes in light-controlled trigger-based senso...

Problems solved by technology

[0003] Based on this, it is necessary to provide a lamp control circuit and sensor lamp that can select the alarm time interval and is not easy to generate false triggers in view of the fact that the sensor lamp cannot independently use lighting or alarm functions, and that the light-controlled sensor lamp is prone to false triggering.
