Abstract
The utility model is specifically related to a kind of night light, including lamp ontology, power circuit, light source and control system, the control system includes pyroelectric infrared sensor, photo resistance, relay, single-chip microcontroller and pressure sensor, the infrared signal output end of the pyroelectric infrared sensor and the signal output end of photo resistance are connect by relay with power circuit, by connecting with single-chip microcontroller, the control output of the single-chip microcontroller is connect by the PWM in power circuit with light source the signal output end of the pressure sensor.The utility model can be by the brightness of the pressure adjusting illuminating lamp of manpower touch pressure sensor, and headlamp slowly lights when making to open, and protects human eyes from stimulation；Pyroelectric infrared sensor incudes human body and photo resistance and incudes light intensity, prevent it is non-artificial open by mistake headlamp, it is easy to use, save electric power.
Description
Technical field
The utility model relates to headlamp field more particularly to a kind of night lights.
Background technique
It when night illumination, turns on light suddenly, the excessively bright lamp from dazzling that moment lights can cause discomfort, to eye disease or mind
People through fatigue is more unfavorable.In addition, headlamp generally requires manual operation, if it is article, non-artificial accidentally touching is opened
Close, either artificially daytime or it is bright and clear in the case where open by mistake headlamp, will also result in power wastage.
Utility model content
The purpose of this utility model is to provide one kind to make user comfortable, and intelligent control, energy saving headlamp.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of night light, including lamp ontology, it is mounted on the intrinsic power circuit of lamp and light source, it further include peace
Mounted in the intrinsic control system of lamp, the control system includes pyroelectric infrared sensor, photo resistance, relay, monolithic
Machine and pressure sensor, the infrared signal output end of the pyroelectric infrared sensor and the signal output end of photo resistance pass through
Relay is connect with power circuit, and the signal output end of the pressure sensor with single-chip microcontroller by connecting, the monolithic
The control output of machine is connect by the PWM in power circuit with light source.
Specifically, the power supply in the power circuit is rechargable power supplies, the charging interface of the rechargable power supplies is arranged
On lamp ontology.
In any of the above-described kind of night light, the light source uses LED cold light source and the outer layer of lamp ontology is arranged in.
Compared with prior art, the utility model has the beneficial effects that 1) manpower touch pressure sensor can be passed through
The brightness of pressure adjusting illuminating lamp, headlamp slowly lights when making to open, and protects human eyes from stimulation；2) rpyroelectric infrared senses
Device incudes human body and photo resistance and incudes light intensity, prevent it is non-artificial open by mistake headlamp, it is easy to use, save electric power；3) light
Source uses LED cold light source and the outer layer of lamp ontology is arranged in, beautiful and saving electric power.
Detailed description of the invention
Fig. 1 is the functional block diagram of technical solutions of the utility model；
Fig. 2 is the structural schematic diagram of the utility model night light；
Fig. 3 is the sectional front view of the utility model night light bottom；
Fig. 4 is the top cross-sectional view of the utility model night light bottom.
In figure: 1, lamp ontology, 2, power circuit, 3, light source, 4, control system, 41, pyroelectric infrared sensor, 42, light
Quick resistance, 43, relay, 44, single-chip microcontroller, 45, pressure sensor, 5, charging interface.
Specific embodiment
The utility model is done below in conjunction with the drawings and specific embodiments and is further described in detail:
Referring to attached drawing 2~4, a kind of night light, including lamp ontology 1, power circuit 2, light source 3 and control system 4, light
The outer layer of lamp ontology 1 is arranged in source 3, and power circuit 2 and control system 4 are located at the bottom and top inside lamp ontology 1.Electricity
Source circuit 2 is rechargeable type, and charging interface 5 is arranged in 1 outer surface of lamp ontology.
Referring to attached drawing 1, control system 4 includes pyroelectric infrared sensor 41, photo resistance 42, relay 43, single-chip microcontroller
44 and pressure sensor 45.When night needing to open headlamp, human body radiation that pyroelectric infrared sensor 41 will receive
Infrared signal lighting lamp circuit is connected by relay 43 with the variation of 42 resistance value of photo resistance；Pressure sensor 45 receives
The pressure signal that manpower touches switchs to electric signal, single-chip microcontroller 44 is conveyed to by amplification module, according to single-chip microcontroller 44 again by telecommunications
Number conversion after value judge pressure size, pass through PWM control headlamp brightness；If non-artificial due to article accidentally touch
Pressure sensor 45 can't accept the infrared signal of human body radiation in the induction range of pyroelectric infrared sensor 41, illumination
Circuit for lamp will not be switched on.When daytime or light become sufficient, the variation that 42 resistance value of photo resistance occurs passes through relay 43
Lighting lamp circuit is cut off, so that headlamp is closed.
