The circuit board and the battery are fixed in the lamp seat. The LED multifunctional intelligent table lamp is characterized in that a single chip microcomputer is used as a control center. Small holes are disposed in the left side of the front end of the lamp seat and can detect light in the environment and infrared rays of a human body. Digital tube displays are arranged in the middle of the front end of the lamp seat and can display grades of light intensity and set time. Two functional buttons are arranged on the right side of the front end of the lamp seat and can be used to adjust the light intensity of the table lamp and the set time. The LED multifunctional intelligent table lamp can still be used to illuminate after a power failure.

Description

A kind of LED multifunctional intellectual desk lamp

Technical field

The utility model relates to a kind of desk lamp, particularly a kind of LED multifunctional intellectual desk lamp of when the ambient light photograph is more weak, reminding the user to turn on light.

Background technology

Employed in the market desk lamp can not remind the user to turn on light when ambient light when more weak, turns on light so the user usually forgets, and is unfavorable to eyes, and desk lamp itself do not possess dimming function and timing function, and power consumption is big, can not throw light on for the user after the outage.

Summary of the invention

The purpose of the utility model is the deficiency of avoiding common desk lamp can not remind the user to turn on light, reminds user to turn on light when more weak and provide a kind of when ambient light, and has light modulation and timing function, the LED multifunctional intellectual desk lamp that still can throw light on after the outage.

The utility model solves the technical scheme that its technical problem adopted: circuit board and battery are fixed in the lamp socket, are the control core with the single-chip microcomputer.There is aperture on the lamp socket front end left side, can detect ambient light photograph and human body infrared.In the middle of the lamp socket front end charactron display is arranged, but display brightness levels and timing.There are two function buttons, the illumination after brightness of scalable desk lamp and timing, battery are used for cutting off the power supply in lamp socket front end the right.

Comprise switching power circuit, mu balanced circuit, display circuit, lighting detecting circuit, human body infrared circuit, key circuit on the circuit board.

Among the design, 220V voltage is through the Switching Power Supply step-down, and one the tunnel supplies power to luminescence unit, and single-chip microcomputer and other circuit supplies are given through mu balanced circuit in another road.Before the people was sitting in desk lamp, the human body infrared circuit was given single-chip microcomputer with detected signal, and when extraneous intensity of illumination was more weak, desk lamp will send alarm sound, reminded the user to open desk lamp.Can in the middle of the lamp socket front end charactron display be arranged through two function button switch desk lamps or setting desk lamp brightness and the timing of regulating the Desk lamp feet front end, but display brightness levels and timing, and there is battery Desk lamp feet inside, still can throw light on after the outage.

The design's beneficial effect is: the human body infrared circuit is arranged, and when extraneous intensity of illumination was more weak, desk lamp will send alarm sound, reminded the user to open desk lamp; Can be through two function button switch desk lamps or setting desk lamp brightness and the timing of regulating the Desk lamp feet front end; In the middle of the lamp socket front end charactron display is arranged, but display brightness levels and timing; There is battery Desk lamp feet inside, still can throw light on after the outage; Luminescence unit adopts led array, and is low in energy consumption.

The specific embodiment

With reference to Fig. 1 this desk lamp is further described; Luminescence unit (2) is embedded in the lampshade (1); Curved boom (9) one ends connect lampshade (1); The other end connects base (11), and hole (5) is detected in the left side of base (11) with illumination in human body infrared detection hole (4), and gray scale display tube (3) and timing display tube (6) are located at the centre position of base (11); Switch key (7) and timing button (8) are located at the right side of base (11), and circuit board (12) is fixed in the inside of base (11).

This TV station circuit for lamp is further described the positive pole of the positive output end sending and receiving light unit (3) of Switching Power Supply (1) and the input in of mu balanced circuit (2), minus earth with reference to Fig. 2; The earth terminal gnd ground connection of mu balanced circuit (2), output out output 5V voltage; The positive pole of lighting detecting circuit (5) meets 5V, minus earth, and output o meets the ADC1 of single-chip microprocessor MCU; The anodal D of human body infrared circuit (6) meets 5V, negative pole G ground connection, and output S meets the ADC2 of single-chip microprocessor MCU; Switch key (10) meets the P3.3 of single-chip microprocessor MCU; Regularly button (11) meets the P3.2 of single-chip microprocessor MCU; Charactron drive circuit (9) meets P3.5, P3.6, the P3.7 of single-chip microprocessor MCU; Charactron (8) connects the output of charactron drive circuit (9); The negative pole of FET (7) drain D sending and receiving light unit (3), grid G meets the P3.4 of single-chip microprocessor MCU, source S ground connection; The positive pole of battery (12) connects Switching Power Supply positive output end, minus earth; The positive pole of buzzer (13) meets 5V, and negative pole meets the colelctor electrode c of triode (14); The base stage b of triode (14) connects the P3.1 of single-chip microprocessor MCU, emitter e ground connection.

Operation principle of the present invention is following:

The 220V civil power is given luminescence unit (3) power supply and is given battery (12) charging through the Switching Power Supply step-down, gives other circuit supplies through mu balanced circuit (2) simultaneously, and the voltage that human body infrared circuit (6) detects the infrared back of human body output S changes; If illumination changes, the voltage of the output o of lighting detecting circuit (5) can change; If single-chip microprocessor MCU detects when taking before desk lamp, and ambient light is according to being lower than setting value, and the P3.1 of single-chip microprocessor MCU becomes high level, triode (14) conducting, and buzzer (13) sends chimes of doom, reminds the user to turn on light.If unmanned before the desk lamp, even ambient light is according to being lower than setting value, desk lamp can not reported to the police yet.

The user can pass through button (10) switch desk lamp and regulate the desk lamp gray scale, can set the desk lamp opening time through button (11), and gray scale and timing are gone up at charactron (8) and shown; The brightness of desk lamp is recently to regulate through the duty of PWM, and dutycycle is different, and the brightness of desk lamp is different, thereby reaches the purpose of light modulation.Timing function then utilizes the single-chip microcomputer timer internal to accomplish, and P3.4 drags down behind the setting-up time, and desk lamp extinguishes.

Behind grid cut-off, the inner battery (12) of Desk lamp feet continues as the desk lamp power supply, thereby is user's illumination.
