Abstract

A door sense light is characterized by comprising a control box (1) arranged in a door, and an infrared distance measurement sensor (2) embedded in the middle part of the door, wherein the control box (1) is internally provided with batteries (3) and a single chip (4); the outer panel of the door is provided with a spotlight (5) and a photoconductive resistance (6); the infrared distance measurement sensor (2) and the photoconductive resistance (6) are connected with the input interface of the single chip (4); and the spotlight (5) is connected with the output interface of the single chip (4). The utility model has strong practicability, can sense that someone is coming at night to automatically turn on the spotlight, brings convenience for the host to take keys to open the door or see clearly the visitors through the peep hole, and is a good helper for home life.

Description

Sense light in front of the door

Technical field

The utility model relates to light fixture, is a kind of sense light in front of the door specifically.

Background technology

Go home evening, very dark in front of the door, draws out key and but where can not find keyhole, gropes half a day, very inconvenient; There is evening the people to knock at the door, sees from opal also not see whom messenger is half a day, do not know whether one is coming or going.It more than is the scene that often runs in the life.In order to find keyhole at night, have the people setting up a small lamp bulb on the key, but how long have more than is needed the button cell that slight key uses is, and change also pretty troublesome.And evening messenger, do not see really, have to ask with sound, may this do not welcome the people who visits to have to open the door to other yet, can make and have no alternative.The door that illumination functions arranged on the market now seldom, so we are sought after a kind of gate light that can inductive lightning.

Summary of the invention

The purpose of this utility model provides a kind of convenient and practical sense light in front of the door.

Described sense light in front of the door is characterized in that: comprise the infrared distance measurement inductor that is installed in the control box in the door and is inlaid in a middle part; Battery, single-chip microcomputer are installed in the described control box, on the outer side panel of door illuminating lamp, photo resistance are installed, wherein infrared distance measurement inductor, photo resistance link to each other with the input interface of single-chip microcomputer, and illuminating lamp links to each other with the output interface of single-chip microcomputer.

This device need cooperate by the built-in program of single-chip microcomputer finishes function corresponding.

The utility model is practical, can respond to messenger at night, opens illuminating lamp automatically, makes things convenient for owner to take key to open the door or see the visitor clearly from opal, and real is the good assistant of life staying idle at home.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is the utility model electrical principle block diagram.

Among the figure: 1-control box, 2-infrared distance measurement inductor, 3-battery, 4-single-chip microcomputer, 5-illuminating lamp, 6-photo resistance 7-keyhole, 8-opal.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified: sense light in front of the door as shown in Fig. 1,2 comprises control box 1 that is installed in a top and the infrared distance measurement inductor 2 that is inlaid in a middle part; Battery 3, single-chip microcomputer 4 are installed in the described control box 1, illuminating lamp 5, photo resistance 6 are installed on the panel of control box 1, wherein infrared distance measurement inductor 2, photo resistance 6 link to each other with the input interface of single-chip microcomputer 4, and illuminating lamp 5 links to each other with the output interface of single-chip microcomputer 4.

Described single-chip microcomputer 4 can use ARM, DSP or other intelligent processor to replace, also can plug-in D/A, and modules such as sound circuit.

Electrical principle block diagram below in conjunction with Fig. 2 carries out the principle explanation.

First-class battery 3 in battery case covers the lid of battery case, enters normal state to be controlled after system's power supply.

Photo resistance 6 is used to distinguish daytime or night.Photo resistance 6 is passed to single-chip microcomputer 4 with the signal that senses, if single-chip microcomputer 4 is judged to be daytime, does not then do any action; If single-chip microcomputer 4 is judged as night, just infrared distance measurement inductor 2 is detected the signal that comes and handle.

If owner goes home or the visitor is arranged, after infrared distance measurement inductor 2 detects, pass the signal to single-chip microcomputer 4, single-chip microcomputer 4 analyzing and processing are controlled illuminating lamp 5 afterwards and are lighted, and owner just can see keyhole clearly and opens the door like this, if the visitor is arranged, just can see clearly from opal has been whom.

When infrared range finding inductor 2 detected nobody once more, single-chip microcomputer 4 control illuminating lamps 5 extinguished.

Claims

1. a sense light in front of the door is characterized in that: comprise the infrared distance measurement inductor (2) that is installed in the control box (1) in the door and is inlaid in a middle part; Battery (3), single-chip microcomputer (4) are installed in the described control box (1), on the outer side panel of door illuminating lamp (5), photo resistance (6) are installed, wherein infrared distance measurement inductor (2), photo resistance (6) link to each other with the input interface of single-chip microcomputer (4), and illuminating lamp (5) links to each other with the output interface of single-chip microcomputer (4).
