Abstract
The invention relates to a delay timing circuit of a sensing switch. The core of the circuit is composed of a delay circuit which is controlled by an NE555 monostability circuit and a relay control circuit. When a person or a vehicle is detected to enter a garage, a triggering signal is transmitted to an NE555 processor and an LED fluorescent lamp is automatically turned on; when the person or the vehicle moves in a parking field, the LED fluorescent lamp keeps lighting; 30 seconds after the person or the vehicle leaves the field, the LED fluorescent lamp is automatically turned off. The delay timing circuit of the sensing switch is applied to the automatic sensing switch of the parking field and used for turning off the LED fluorescent lamp in 30 seconds after the person or the vehicle leaves the parking field.
Description
Technical field
The present invention relates to LED daylight lamp circuit field, be specifically related to a kind of delay timing circuit of inductive switch.
Background technology
From the end of the sixties in 19th century, since GaAs uses phosphide to invent first visible infrared LED on substantially, along with the breakthrough of the technology such as semiconductor and LED encapsulation, power grade and the brightness of single-chip red, green, blue, white light LEDs constantly improve.Along with LED light efficiency, life-span and photochromic on obvious raising, its showing, there are huge potentiality in the field such as backlight, decoration and illumination.Although LED application constantly expands, life-span and light efficiency are higher than traditional lighting.But cost is relatively high, LED light source cost proportion up to 50% ~ 90%, improves technical the needing of lighting source in total cost, and great power LED cooling and light efficiency problem highlight, and this has limited the further application of LED in lighting field.
Summary of the invention
The problem existing for prior art, the object of this invention is to provide a kind of delay timing circuit of inductive switch, the automatic control of this lighting device based on microwave technology, light intensity lower than certain limit in, in the time having people to enter inductive switching scope, LED fluorescent lamp is opened automatically, after people leaves, and switch automatic delay function LED fluorescent lamp.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of delay timing circuit of inductive switch, comprise NE555 processor, between the OUT port of NE555 processor and GND port, be connected with relay, the VCC port of NE555 processor is connected by the THR port of resistance R 1 and NE555 processor, the THR port of NE555 processor is connected with OIS port, the RST port of NE555 processor is connected with VCC port, the TRI port of NE555 processor is connected with one end of resistance R 2, the other end of resistance R 2 is connected on the circuit between resistance R 1 and the VCC port of NE555 processor, the CON port of NE555 processor is connected by the GND port of capacitor C 2 and NE555 processor, capacitor C 1 one end is connected with resistance R 1, the GND port of capacitor C 1 other end and NE555 processor is connected, relay coil parallel connected in reverse phase a diode D.
The present invention compared with prior art has the following advantages:
1. the present invention is reasonable in design, simple in structure and circuit part line is simple;
2. adopt the LED lighting circuit of inducing function, LED energy-saving daylight lamp is to use novel PIR technology and efficient white light LEDs, and the movement of detecting human body or thermal source also starts lamp automatically, after human body or vehicle leave, lamp automatic distinguishing, does not need to touch any switch, convenient energy-conservation again.Meanwhile, this product possesses delay function,, after people or other thermals source leave, after LED lamp certain time, extinguishes; Can prevent the continuous unlatching of LED lamp and extinguish the impact on the LED lamp life-span causing.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
With reference to accompanying drawing, a kind of delay timing circuit of inductive switch, comprise NE555 processor, between the OUT port of NE555 processor and GND port, be connected with relay, the VCC port of NE555 processor is connected by the THR port of resistance R 1 and NE555 processor, the THR port of NE555 processor is connected with OIS port, the RST port of NE555 processor is connected with VCC port, the TRI port of NE555 processor is connected with one end of resistance R 2, the other end of resistance R 2 is connected on the circuit between resistance R 1 and the VCC port of NE555 processor, the CON port of NE555 processor is connected by the GND port of capacitor C 2 and NE555 processor, capacitor C 1 one end is connected with resistance R 1, the GND port of capacitor C 1 other end and NE555 processor is connected, relay coil parallel connected in reverse phase a diode D.
Operation principle of the present invention is:
The delay circuit of monostable circuit control and control relay circuit are core, and in the time having detected that people or vehicle enter into garage, triggering signal sends to NE555 processor, and LED fluorescent lamp is lighted automatically; People or vehicle are walked about in parking lot, and LED fluorescent lamp continues to light; People or vehicle leave LED fluorescent lamp after 30S and automatically close.
The delay circuit of monostable circuit control is characterised in that and receives the triggering signal that trigger end is given, triggering signal voltage is added to the trigger end of NE555 processor by capacitor C 2, make the output of the trigger end of NE555 processor become high level from low level, relay adhesive, electric light is lighted; When can't detect people or vehicle, trigger end has when mobile, power supply is by charging to capacitor C 1, when the voltage in capacitor C 1 rise to supply voltage 2/3 time, the DIS pin conducting of NE555 processor is discharged capacitor C 1, the output of NE555 processor has high level to become low level again, relay discharges, lights, and timing finishes.
Relay circuit is characterized in that mainly containing relay and diode composition; the lighting and extinguish of the open close LED of control fluorescent lamp by relay; relay coil parallel connected in reverse phase a diode D; it is for the protection of integrated package; prevent from the time that relay transfers off-state to by attracting state, producing higher reactionary style, integrated package is punctured.
