Technical Field

The utility model relates to a study lamp technical field, a myopia prevention protects backbone study lamp specifically says so.

Background

According to statistics, the incidence of myopia of primary school students, junior middle school students and high school students in China is as follows: 27%, 53%, 73%. The vision reduction rate of graduates in high school and high school in the cities along the coast reaches 85 percent, the myopia of China is the second place worldwide, and the number of people with teenagers who suffer from myopia and blindness reaches 30 ten thousand. The most students have poor eyesight due to insufficient reading and writing distance, bad sitting posture and the like, so that the myopia-preventing spine-protecting learning lamp for preventing myopia, protecting the spine and correcting the sitting posture is designed.

Disclosure of Invention

A myopia-preventing spine-protecting learning lamp comprises a learning lamp body, an infrared human body sensor, an infrared distance-measuring photoelectric switch and a control box, wherein the learning lamp body is provided with a power plug, a learning lamp switch, a lamp holder supporting rod, a lamp bead, a wireless receiving module, a receiving antenna, an electric wire and a lamp bead conducting wire; the infrared human body sensor, the infrared distance measurement photoelectric switch and the control box are generally arranged on a table and are respectively connected through a battery wire, an infrared human body sensor wire and an infrared distance measurement photoelectric switch wire, and a battery, a wireless transmitting module, a transmitting antenna and a loudspeaker are arranged in the control box.

When a learner uses the myopia-preventing spine-protecting learning lamp and the body is close to a desk, due to the fact that the human body has temperature, all objects with temperature radiate infrared rays to the outside, the infrared rays emitted by the human body are detected by the infrared human body sensor arranged on the desktop, at the moment, the infrared human body sensor supplies power to the infrared distance-measuring photoelectric switch to enable the infrared distance-measuring photoelectric switch to work, the working principle of the infrared distance-measuring photoelectric switch is similar to the radar principle, the infrared distance-measuring photoelectric switch emits infrared rays upwards, the infrared rays are reflected back when meeting obstacles, the infrared distance-measuring photoelectric switch can judge the distance between the obstacles according to the emitted infrared rays, when the learner sits in front of the desk and uses a desk lamp, the infrared distance-measuring photoelectric switch detects that the head of the learner is too close to the desktop, for example, the infrared distance-measuring photoelectric switch is arranged so that the distance between the obstacles (the position of the chin of the head of the learner) and the desktop is lower than 18cm, the infrared distance measurement photoelectric switch supplies power to the loudspeaker and the wireless transmitting module in the control box to enable the loudspeaker and the wireless transmitting module to work, at the moment, the loudspeaker gives out sound warning, the wireless transmitting module sends out wireless signals through the transmitting antenna, the sent wireless signals are received by the receiving antenna in the table lamp main body and fed back to the wireless receiving module, the wireless receiving module takes power limiting measures on the learning lamp bead after receiving the signals, the learning lamp bead is turned off or brightness is reduced for warning, a learner cannot learn due to insufficient light, and is forced to correct a sitting posture and use eyes, when the head of the learner is far away from a desktop, correct the sitting posture and use eyes, the infrared distance measurement photoelectric switch removes the power supply to the loudspeaker and the wireless transmitting module, and all warnings are removed; the wireless receiving module is powered by a household power supply, and the infrared human body sensor is powered by a battery in the control box. When the learner turns off the learning lamp in the daytime and does not need illumination, and the learner has bad sitting posture and uses eyes at a short distance, the infrared human body sensor and the infrared distance measurement photoelectric switch work normally, and the horn in the control box still plays a warning role. The wireless receiving and transmitting module is a same-frequency super-regenerative wireless receiving and transmitting module or a same-frequency infrared wireless receiving and transmitting module, and the frequency is different from the infrared frequency emitted by a human body and the infrared frequency emitted by an infrared ranging photoelectric switch and does not interfere with each other.

To sum up, the design effectively solves the problem that the existing market has good effects of preventing myopia, protecting the spine and correcting sitting posture.
