Problems solved by technology

[0003] Whether it is infrared sensing or radar sensing, the sensing module built into the lamp detects extremely weak signals, and its amplitude is very small, which is easily affected by the interference of the environment and power supply to cause false sensing; and the principles of both are the same. Only when a moving human body is detected can it be sensed, and a fixed human body cannot be sensed; moreover, the fixed lighting time consumes electricity and energy; the above are the three common problems of traditional induction lamps

Abstract

A wirelessly-controlled LED lamp induction circuit comprises a low-voltage direct-current power supply module, a wireless control module and a light-emitting module. The low-voltage direct-current power supply module is used for converting an input voltage into a power supply voltage of the wireless control module; the wireless control module is connected with the light-emitting module, the wireless control module comprises a Bluetooth module, and the Bluetooth module is used for monitoring whether a device sends an effective broadcast message on a Bluetooth broadcast channel in an induction area and outputting a dimming signal for turning on or turning off a lamp to the light-emitting module; and the light-emitting module comprises a dimming switch circuit and an LED lamp string, and the dimming switch circuit is used for receiving a dimming signal from the wireless control module and controlling the lighting state of the LED lamp string according to the dimming signal. Compared with a traditional induction mode, the LED lamp induction circuit does not trigger mistakenly, induction can be achieved without movement of the human body, more importantly, the lamp is turned on when people come and turned off when people leave, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a wirelessly controlled LED lamp induction circuit. Background technique [0002] Traditional human body sensing LED lights are usually divided into two categories, one is infrared sensing, which detects the infrared rays emitted by a moving human body through the built-in pyroelectric head (PIR) of the lamp, and judges whether someone has entered the range of the sensing light according to the detection results , and turn on the LED light, and turn off the LED light after a fixed period of time (usually 3 to 10 minutes) after the last detected movement of the human body; Waves are reflected by moving objects (including moving human bodies) and received by the receiving antenna of the microwave radar module. The radar module judges whether someone has entered the range of the sensing lamp by calculating the sent signal and the received signal, and lights up the LED lamp. Af...
