Embodiment Construction

[0011] figure 1 It is a schematic diagram of the implementation of an adjustable anti-myopia desk lamp of the present invention, as figure 1 shown. The table lamp specifically includes: 1. The base of the table lamp; 2. The window of the ultrasonic rangefinder; 3. The switch; 4. The input panel for the sitting height of people of different ages (the distance between the human body and the eyes starting from the horizontal desktop); 5. The lamp Column; 6. Bulb (energy-saving lamp or ordinary bulb can be used); 7. Lampshade. When the switch is turned on, the ultrasonic rangefinder works, and the sitting height data (height) of the panel is input, and the operator sends a trigger signal to the control circuit. When the condition is met, the control circuit is connected, and the desk lamp is turned on (bright), otherwise the desk lamp is turned off (dark). ),

[0012] The specific implementation is: when the power is plugged in, the switch is turned on, the ultrasonic range fin...

Abstract

The invention discloses a myopia-prevention desk lamp. An ultrasonic distance measuring instrument is arranged on the lateral side of a base of the desk lamp. When ultrasonic waves are horizontally emitted to a student body, the horizontal distance xcm from a book to the student body is obtained, the distance ycm from the desk top serving as a starting point to eyes of a student is inputted via a panel of the desk lamp, by calculating the result of x<2> + y<2> via a calculator in the base of the desk lamp, a trigger signal is transmitted to control on and off of the desk lamp through a control circuit. When the x<2> + y<2>>/=302cm<2>, the desk lamp is turned on, and when the x<2> + y<2></=302cm<2>, the desk lamp is turned off. On and off of a bulb of the desk lamp is controlled according to the measured distance, and accordingly, the student can be prompted of correct writing posture and distance, and the problem about sight diminution due to the fact that the student is too closer to books when writing or reading is solved.

Description

technical field [0001] The invention relates to a desk lamp, in particular to an adjustable anti-myopia desk lamp. Background technique [0002] Traditional desk lamps are mainly used for lighting. When people are working, reading books, reading newspapers and students are doing homework, their eyes are usually less than 30cm away from the books. If things go on like this, it will lead to vision loss or hunchback, which will affect people's study, work and students' growth . Contents of the invention [0003] Due to the shortcomings of traditional desk lamps, after repeated thinking and experiments, the team finally successfully developed an adjustable anti-myopia desk lamp with excellent performance. This desk lamp can adjust the safe distance between books and students' eyes according to students of different ages, effectively solving The problem of hunchback and myopia when students read and write can achieve the ideal effect of preventing myopia and hunchback.
