Abstract
The utility model relates to a computer intelligent controlled anti-myopia lamp, which comprises a lamp body, a lamp arranged on the lamp body and a switch. The utility model is provided with a rectification circuit, an infrared light emitting circuit, an infrared light receiving circuit, a photoelectric converting circuit, a photoelectric switch, an alarming time delay control circuit and a non-contact switch circuit. An infrared emitting tube in the infrared light emitting circuit and an infrared receiving tube in the infrared light receiving circuit are arranged on the lamp body. Due to the structure adopted by the utility model, when a sitting position and a read-write distance of a user are not proper, the lamp is forcibly turned off by a lighting circuit because the infrared tubes are shielded by monitored parts of a human body, the alarming time delay control circuit sends out prompting sounds to force the user to correct the read-write distance and the sitting position, and the lamp is returned to normal illumination when the read-write distance and the sitting position satisfy requirements. Therefore, the utility model achieves the purpose of preventing myopia caused by unhealthy sitting posture and read-write distance.
Description
Technical field the utility model relates to a kind of Computerized intelligent myopia prevention lamp.
The present students in middle and primary schools of background technology are bad because of reading/writing distance control, the bad phenomenon of spinal curvature, cardiopulmonary pathology that causes of sitting posture is more general, and particularly the adolescent myopia rate rises year by year.For pre-myopia prevention, people have proposed multiple myopia prevention lamp, generally comprise lamp body, be located at fluorescent tube, switch and control circuit on the lamp body.This class myopia prevention lamp mainly is to reduce stimulation to human eye by the soft degree of regulating light, in the hope of reaching the purpose of pre-myopia prevention.For the myopia that phenomenons such as reading/writing distance is too near, sitting posture is bad cause, above-mentioned myopia prevention lamp obviously can't play the purpose of prevention.
Utility model content the utility model provides a kind of Computerized intelligent myopia prevention lamp exactly for addressing the above problem, sitting posture and reading/writing distance when this myopia prevention lamp can be monitored the user and learns; When too near or sitting posture was bad when user's reading/writing distance, the utility model can send alarm signal, even cuts off the electricity supply.
The technical scheme that the utility model provides is: a kind of Computerized intelligent myopia prevention lamp, comprise lamp body, be located at fluorescent tube and switch on the lamp body, its key is to be provided with rectification circuit, infrared light radiating circuit, infrared light receiving circuit, photoelectric switching circuit, optoelectronic switch and caution delay control circuit and non-contact switch circuit, and the infrared receiving tube in infrared transmitting tube in the infrared light radiating circuit and the infrared light receiving circuit is located on the lamp body.
The utility model also is provided with the language circuit.
Lamp body of the present utility model is provided with tube rack, and the infrared tube in infrared tube in the infrared light radiating circuit and the infrared light receiving circuit is located on the tube rack.
The utility model is owing to adopt said structure, sitting posture when the user learns and reading/writing distance were not at that time, infrared tube is subjected to blocking of the monitored position of human body, lighting circuit will force to cease lamp, the caution delay control circuit sends prompting sound, force the user to correct reading/writing distance and sitting posture, meet the requirements until reading/writing distance and sitting posture and recover normal illumination again, thereby reach prevention because of incorrect sitting-pose and the improper purpose that causes myopia of reading/writing distance.
