Description

An induction desk lamp

technical field

The utility model relates to a desk lamp, in particular to an induction desk lamp.

Background technique

In work and study, because people's sitting posture is not correct, such as hunched over the table and other incorrect sitting postures, the distance between the eyes and the book or the distance from the computer is too close, resulting in more and more people with myopia. Many, especially some elementary school students, sit incorrectly for a long time, and the eyes are too close to the books, which can easily cause myopia, and the long-term incorrect sitting posture is also prone to hunchback, which seriously affects health.

And in the prior art, the desk lamp that people use in work and study is generally all by manual control, just manually desk lamp is opened when work or study, just closes when not working, like this, can not help people reach the correct sitting posture Purpose.

Utility model content

The technical problem mainly solved by the utility model is to provide an induction desk lamp, which can solve the technical problems of myopia and hunchback caused by incorrect sitting posture for a long time during work and study.

In order to solve the above-mentioned technical problems, a technical solution adopted by the utility model is to provide an induction table lamp, which includes a lamp body and a light bulb arranged on the light body, and a switch for controlling whether the light bulb is on or off is arranged on the light body. A switch, the switch is an infrared induction switch.

Wherein, the lamp body has a lamp holder and a lamp post placed on the lamp holder, the other end of the lamp post opposite to the lamp holder is provided with a lampshade for accommodating the bulb, and the infrared sensor switch is located on the lamp holder or the lampshade .

Wherein, the switch includes a controller, an infrared sensing probe and a relay, the controller is connected to the relay and the infrared sensing probe, and the relay is connected between the external power supply and the light bulb.

Wherein, a plug is included, and the lamp body and the plug are connected by wires.

The beneficial effects of the utility model are: different from the desk lamp in the prior art, which cannot help the user to correct the sitting posture, the incorrect sitting posture of the user for a long time causes myopia and hunchback to affect the health of the user. The induction desk lamp of the utility model can force the user to make his sitting posture correct, that is, the distance between the user and the desk lamp is within a certain distance range, such as 30cm-60cm, and when the distance between the user's eyes and the desktop is within the distance range of 30cm-40cm, The switch of the induction table lamp will be turned on automatically, and the light bulb will be turned on automatically, otherwise the switch will be disconnected, and the light bulb of the induction table lamp will not be on, so as to help users correct their sitting posture, so that they can work and study under the table lamp for a long time without myopia or hunchback the goal of.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to Fig. 1 and Fig. 2, the induction table lamp of the present utility model comprises a lamp body 10, and described lamp body 10 has a lamp holder 14 and a lamp post 15 that is placed on lamp holder 14, and described lamp post 15 is opposite lamp holder The other end of 14 is provided with a lampshade 16 for accommodating the bulb 11. The lamp holder 14 of the lamp body 10 is connected with a plug 12 with a wire, and the plug 12 is plugged with an external power socket. The lamp body 10 is also provided with a switch 13 , in this embodiment, the switch 13 is an infrared sensor switch, including a controller 22 , an infrared sensor probe 21 and a relay 23 . The infrared sensor switch is located on the lamp holder 14 or the lampshade 16 .

Please continue to refer to Fig. 2, which is a schematic block diagram of the induction desk lamp of the present invention, including a power supply 20, a relay 23 connected to the power supply 20, a bulb 11 connected to the relay 23, and a power supply 23 connected to the relay 23. The controller 22 is connected with an infrared sensing probe 21 . Both the controller 22 and the relay 23 are arranged inside the lamp holder 14 , and the infrared sensing probe 21 is located on the lamp holder 14 or the lampshade 16 .

When using the induction desk lamp, plug the plug 12 into the power socket, and then the user sits down with the correct sitting posture, that is, keep the distance between the person and the induction desk lamp at 30cm-60cm, and the distance between the eyes and the desktop at 30cm-40cm Within the distance range, the infrared sensing probe 21 receives the infrared signal sent by itself and reflected back by the user's body, the infrared signal triggers the controller 22 to control the relay 23 to close, and at this time the bulb 11 of the induction desk lamp will light up, and the user When the sitting posture is correct for reading and working, the bulb 11 of the induction desk lamp will always be on. If the user leaves or the sitting posture is not correct, that is, when the distance range exceeds the above-mentioned range, the infrared sensing probe 21 will not receive the light emitted by itself and reflect The returned infrared signal cannot trigger the controller 22 to control the relay 23 to close at this moment, and the bulb 11 will automatically go out. In this way, the purpose of reminding the user to correct the sitting posture can be achieved. When the user leaves, the bulb 11 of the induction desk lamp is automatically extinguished, which can prevent the situation that the user forgets to turn off the power supply when leaving or turns off the desk lamp so that the bulb is always on and wastes power.

Different from the desk lamp in the prior art, it can not help the user to correct the sitting posture, and the incorrect sitting posture of the user will cause myopia and hunchback to affect the health of the user. The induction desk lamp of the utility model can be according to the user's sitting posture situation, namely the distance between the user and the desk lamp is 30cm～60cm, when the distance between the user's eyes and the desktop is within the distance range of 30cm～40cm, the bulb 11 of the induction desk lamp will automatically Otherwise, the bulb 11 of the induction desk lamp will not be bright, so as to help the user correct his sitting posture and ensure his health.

In summary, the induction desk lamp of the utility model can force the user to sit in a correct posture, that is, the distance between the user and the desk lamp is 30cm-60cm, and the distance between the user's eyes and the desktop is within the range of 30cm-40cm for work and study. Otherwise, the light bulb 11 of the induction desk lamp will be automatically extinguished, so that the purpose of working and learning under the desk lamp for a long time is not short-sighted and hunchbacked.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
