A kind of desk lamp
Technical field
The utility model relates to a kind of desk lamp, relates in particular to a kind of multi-function desk lamp, belongs to the desk lamp field.
Background technology
Desk lamp is a kind of electric lighting commonly used in the daily learning life of people.Desk lamp normally is placed on desk or head of a bed place, and common desk lamp only can be for illumination, function singleness, and be hand control switch mostly, it is convenient not to use.For the people who needs every day and regularly get up, alarm clock is the necessary instrument that gives the correct time, or with mobile phone, quarter-bell is set, or places specially an alarm clock, and this has also occupied the confined space of desk or the head of a bed to a certain extent, is unfavorable for clean and tidy.The product that desk lamp combines with alarm clock does not also appear at present.
The utility model content
The purpose of this utility model is: propose a kind of desk lamp in conjunction with alarm clock function, to improve the use value of desk lamp.
This desk lamp comprises bulb, also comprise microcontroller, alarm clock module, lighting circuit, action sensor, display unit, key circuit and power circuit, wherein: microcontroller is by the lighting circuit connection bulb, the alarm clock module is by the microcontroller implementation alarm clock function, key circuit by microcontroller implementation to the control of alarm clock module with to the adjusting of bulb light, display unit all is connected with microcontroller with action sensor, and power circuit is for powering to each power unit.
Further, described alarm clock module comprises clock circuit and buzzer.
Further, described key circuit comprises that alarm clock arranges button, alarm clock stop button, light adjusting knob and bulb switch.
Preferably, described display unit adopts LCD display.
Technique effect:
1, alarm clock is combined to design with desk lamp, novel structure, be beneficial to and save space, improved practicality simultaneously.
2, desk lamp can be realized automatic control function by action sensor, is beneficial to the saving electric energy.
3, the lamp bulb luminous intensity is adjustable, and design is than hommization.
The accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
The specific embodiment
Below the utility model is described in further detail.
The structure of the utility model desk lamp as shown in Figure 1, comprise bulb, microcontroller, alarm clock module, lighting circuit, action sensor, display unit, key circuit and power circuit, wherein: microcontroller is by the lighting circuit connection bulb, the alarm clock module is by the microcontroller implementation alarm clock function, key circuit by microcontroller implementation to the control of alarm clock module with to the adjusting of bulb light, display unit all is connected with microcontroller with action sensor, and power circuit is for powering to each power unit.
The alarm clock module comprises clock circuit and buzzer; Key circuit comprises that alarm clock arranges button, alarm clock stop button, light adjusting knob and bulb switch, alarm clock arranges button for date and time is set, the alarm clock stop button for closing the sound that gives the correct time when alarm clock sounds, the light adjusting knob is for rotating the intensity of regulating light, and bulb switch is the power switch of desk lamp; Microcontroller adopts the MSP430 chip microcontroller of the high integration of TI company; Lighting circuit comprises rectification circuit and potentiometer circuit, for the Current Control of bulb; Action sensor is for detection of people's actuating signal, and its induction mouth is towards the human body direction; Display unit adopts the small LCD display screen, and this display screen can show current date, time and alarm time by numeral, and, with backlight function, is convenient to check the time at night; Power circuit, for connecting mains supply, carries out voltage transitions, and it,, to provide+5V of microcontroller D.C. regulated power supply, provides the 220V alternating current to lighting circuit.
During use, set alarm time, normally open desk lamp, and be adjusted to suitable intensity of light.After arriving alarm time, the buzzer newspaper is named, and only presses after the alarm clock stop button newspaper and cries just and stop.Action sensor detects in real time, after detecting without human action, (regards as sleep), and the Automatic control of single chip microcomputer lighting circuit cuts out, or it is dimmed to control light, plays energy-conserving action.
