Description

I. TECHNICAL FIELD

[0001] The present case belongs to the field of small household appliances necessary for students, and is the development direction of eye protection engineering technology for caring for primary and secondary school students. II. BACKGROUND

[0002] Nowadays, primary and secondary school students pursue quality education, and the curriculum is diversified. The state also advocates reducing the burden on students and takes practical action, such as banning primary and secondary school basic course teaching institutions. However, it is undeniable that students wearing glasses are becoming younger and younger, and even second-grade students have started to wear glasses. The problem is where it is. In the 1980s and 1990s, rural children studied with kerosene lamps, often studying late at night, and no students wore glasses, but some students' families used agricultural lighting electricity after that, students read and studied under fluorescent light, and wore glasses after three years.

[0003] Through comparative analysis, we can know that students reading and studying under sunlight and lighting produced by burning heat are beneficial to the eyes. In view of this, the present case makes innovative thinking, taking into account the safety of fire use, and proposes a new reading and learning lighting scheme - a burning light eye protection desk lamp. III. SUMMARY

[0004] The purpose of the present invention is to provide a burning light eye protection desk lamp.

[0005] The present case is a burning light eye protection desk lamp, which is composed of a 220V AC power supply 1, a 220V AC power supply switch 2, a rectifier device 3, a filter device 4, a DC voltage stabilizing device 5, and a tungsten filament electric bulb 6. Among them, the output end of the 220V AC power supply 1 is connected with the input end of the 220V AC power supply switch 2 through a wire, the output end of the 220V AC power supply switch 2 is connected with the input end of the rectifier device 3 through a wire, the output end of the rectifier device 3 is connected with the input end of the filter device 4 through a wire, the output end of the filter device 4 is connected with the input end of the DC voltage stabilizing device 5 through a wire, and the output end of the DC voltage stabilizing device 5 is connected with the tungsten filament electric bulb 6 through a wire.

[0006] In the figure, the tungsten filament electric bulb 6 is powered by a DC power supply, and the tungsten filament in the tungsten filament electric bulb 6 generates light by heating, which is used for lighting when students read and study.

[0007] The invention can provide eye protection lighting and heating light for students reading and studying, and delay the premature approximation of students' eyes due to fatigue. IV. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 is a working principle block diagram of the burning light eye protection desk lamp. Figure 1 V. DETAILED DESCRIPTION

[0009] ​The present application is a kind of light burning eye protection table lamp, which can provide light for students to read and study, delay the students' eyes from fatigue and premature.

[0010] The light burning eye protection table lamp is connected with 220V AC power supply 1 output end and 220V AC power supply switch 2 input end by wire, then connected with 220V AC power supply switch 2 output end and rectifier device 3 input end by wire, then connected with rectifier device 3 output end and filter device 4 input end by wire, then connected with filter device 4 output end and DC voltage stabilizing device 5 input end by wire, finally connected with DC voltage stabilizing device 5 output end and tungsten filament electric bulb 6 by wire.

[0011] The light burning eye protection table lamp works, 220V AC power supply switch 2 is opened, rectifier device 3 converts 220V AC power supply 1 into DC, filter device 4 filters the DC, DC voltage stabilizing device 5 stabilizes the filtered DC, provides constant voltage and constant current DC for tungsten filament electric bulb 6, makes tungsten filament electric bulb 6 emit stable burning light, provides light for students to read and study.

[0012] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not the limitation of the embodiments of the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived from the spirit of the present application are still within the protection scope of the present application.
