Description

a desk lamp

technical field

The invention relates to a desk lamp, in particular to a multifunctional desk lamp, which belongs to the field of desk lamps.

Background technique

Desk lamp is a kind of lighting appliance commonly used in people's daily study and life. The desk lamp is usually placed on the desk or at the head of the bed. The common desk lamp can only be used for lighting, has a single function, and is mostly a manual control switch, which is not convenient enough to use. For people who need to get up regularly every day, the alarm clock is a necessary tool for telling the time. Either use a mobile phone to set the alarm, or place a special alarm clock, which also occupies the limited space on the desk or bedside to a certain extent, which is not conducive to tidiness. Also do not have the product that desk lamp and alarm clock combine at present.

Contents of the invention

The object of the present invention is to provide a desk lamp combined with an alarm clock function to improve the use value of the desk lamp.

The desk lamp includes a light bulb, and also includes a microcontroller, an alarm clock module, a lighting circuit, a motion sensor, a display unit, a button circuit and a power supply circuit, wherein: the microcontroller is connected to the light bulb through the lighting circuit, and the alarm clock module realizes the alarm clock function through the microcontroller, The button circuit realizes the control of the alarm clock module and the adjustment of the bulb light through the microcontroller, the display unit and the motion sensor are connected with the microcontroller, and the power circuit is used to supply power to each power consumption unit.

Further, the alarm clock module includes a clock circuit and a buzzer.

Further, the button circuit includes an alarm clock setting button, an alarm clock stop button, a light adjusting knob and a light bulb switch.

Preferably, the display unit is an LCD display.

Technical effect:

1. Combining the design of the alarm clock and the table lamp, the structure is novel, which is beneficial to save space and improve the practicality at the same time.

2. The table lamp can realize the automatic control function through the motion sensor, which is beneficial to save electric energy.

3. The light intensity of the bulb is adjustable, and the design is more humanized.

Fig. 1 is a structural block diagram of the present invention.

Detailed ways

The present invention will be further described below.

The structure of desk lamp of the present invention is as shown in Figure 1, comprises bulb, microcontroller, alarm clock module, lighting circuit, motion sensor, display unit, button circuit and power supply circuit, wherein: microcontroller connects bulb through lighting circuit, and alarm clock module passes through The microcontroller realizes the alarm clock function, and the button circuit realizes the control of the alarm clock module and the adjustment of the bulb light through the microcontroller, the display unit and the motion sensor are connected with the microcontroller, and the power supply circuit is used to supply power to each power consumption unit.

The alarm clock module includes a clock circuit and a buzzer; the button circuit includes an alarm clock setting button, an alarm clock stop button, a light adjustment knob and a light bulb switch, the alarm clock setting button is used to set the date and time, and the alarm clock stop button is used to turn off the sound when the alarm clock sounds , the light adjustment knob is used to rotate and adjust the intensity of the light, and the light bulb switch is the power switch of the desk lamp; the microcontroller is realized by the highly integrated MSP430 single-chip microcomputer of TI Company; the lighting circuit includes a rectifier circuit and a potentiometer circuit, which is used for the light bulb Current control; the motion sensor is used to detect human motion signals, and its sensing port faces the direction of the human body; the display unit adopts a small LCD display, which can display the current date, time and alarm clock time in numbers, and has a backlight function, which is convenient Check the time at night; the power circuit is used to connect to the mains power supply for voltage conversion, which provides +5V DC regulated power supply to the microcontroller and 220V AC power to the lighting circuit.

When in use, set the alarm clock time, turn on the desk lamp normally, and adjust to a suitable light intensity. When the alarm clock time is reached, the buzzer will call, and the call will stop only after the alarm clock stop button is pressed. The motion sensor detects in real time. When no one is detected (recognized as sleep), the single-chip microcomputer automatically controls the lighting circuit to turn off, or controls the light to dim to save energy.
