6. Desk lamp base, 7. Telescopic rod, 8. Desk lamp cover, 9. Signal amplifier, 10. Control switch.

Detailed ways

The specific embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the utility model. It should be understood that although the invention has been described in connection with preferred specific embodiments thereof, these embodiments are intended to illustrate, not limit the scope of the invention.

As shown in Figure 1, the figure includes:

Processor 1;

The infrared sensor 2 is used to sense the height of the user's head;

Alarm 3, used to send out an alarm sound;

The timer 4 is used to record and display the time used by the desk lamp; the timer 4 includes a crystal oscillator capacitor and a digital tube.

The LED lamp 5 is used to emit a flashing light;

The infrared sensor 2, the alarm 3, the timer 4, and the LED light 5 are respectively connected to the processor 1 through wires.

Processor 1 is a C51 single-chip microcomputer, which is the main body of the entire single-chip microcomputer system. Programs are written in processor 1 to realize information collection and processing. It can also analyze and record three states of the user: correct state, head down state, and fatigue state.

As shown in Figure 2, the utility model also includes a desk lamp base 6, which is provided with a telescopic rod 7 perpendicular to the desk lamp base 6, scales are arranged on the telescopic rod 7, which is convenient for height adjustment, and the infrared sensor 2 is located on the telescopic rod 7. The top of the desk lamp base 6 is provided with a lampshade 8, and a lamp tube is installed in the desk lamp shade 8. The processor 1 is connected with the alarm 3 through a signal amplifier 9, and the alarm 3 is a buzzer. The utility model also includes a power supply (not shown) for powering the processor 1 . The utility model also includes a control switch 10 for controlling the power supply of the processor 1 .

Before the utility model is used, it is necessary to set the placement position of the desk lamp, then adjust the height of the telescopic rod 7 and fix it to ensure that the infrared sensor 2 is facing the user, and then press the control switch 10 to make it communicated, and Start the desk lamp. The height of the infrared sensor 2 from the lamp base 6 is preferably 40 cm. The sensing range of the infrared sensor 2 is relatively low, and the sensing height near the user is about 30 cm. Under normal circumstances, the distance between the eyes and the table is 30-40 cm. Best left and right.

When the utility model is in use, when the user of the table lamp lowers his head in the state of turning on the light or the head is lowered due to deformation of the sitting posture, the infrared sensor 2 will sense and send an electrical signal to the processor 1, and the processor 1 will send an electric signal to the alarm. 3 sends an instruction, and the alarm 3 sends an alarm sound to remind the user to look up and adjust the correct sitting posture. After the user adjusts the distance between the eyes and the desktop to be greater than 30 centimeters, the alarm device 3 will stop the alarm. The lower control switch 10 (popped up) makes it connected, and the power supply of the single-chip microcomputer system is restored. After the user turns on the light, press the control switch 10, and the timer 4 starts counting from zero. After a certain period of time (such as 45 minutes) preset, the timer 4 will send an electrical signal to the processor 1, The processor 1 sends instructions to the LED light 5, and the LED light 5 emits a flashing light to remind the user to leave the desk for a rest. When the user gets up to rest, press the control switch 10 to make it pop up, so that the entire single-chip microcomputer system is powered off, and the LED light 5 stops flashing, presses the control switch 10 to make it connected, and the single-chip microcomputer system recovers the power supply.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. It should be regarded as the protection scope of the present utility model.
