Double-tube light for classrooms

Abstract

The invention discloses a double-tube light for classrooms. The double-tube light comprises two fluorescent tubes, a reflector mainboard and reflector side plates, wherein the two fluorescent tubes and the reflector mainboard are arranged at a bottom reflector fixing seat; the reflector side plates are arranged at two sides of the reflector mainboard, and two sides of the reflector mainboard are symmetrical and are bent inwards continuously to form a plurality of rectangular narrow-strip-shaped planes, and the number of the narrow-strip-shaped planes is from 16 to 22; and the fluorescent tubes are arranged at the focus of the reflector mainboard. The double-tube light for classrooms has lighting efficiency of higher than 70% and is quite suitable for electric classrooms.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a lighting fixture specially used in a classroom lighting environment, and belongs to the technical field of electric light source equipment. Background technique [0002] The classroom is an important place for students to learn. The selection of lamps is related to the visual comfort, concentration and eye health of teachers and students. According to the latest figures released by the Ministry of Education, my country's myopia rate ranks second in the world, with 28% of primary school students, 60% of junior high school students, and 85% of high school students. The lighting environment of the classroom directly affects the visual development of students. At present, the lighting indicators of lamps and lanterns commonly used in classrooms of primary and secondary schools in my country have not yet reached the requirements of the national "Architectural Lighting Design Standards" (GB5003...

AI Technical Summary

Problems solved by technology

First of all, the reflector main boards of the existing double-tube lighting fixtures used in classrooms are all made of curved surfaces, which makes the efficiency of the lamps low, the light intensity distribution does not meet the requirements, and there are poor illumination, large glare, large flicker and Insufficient energy consumption, etc., so the light distribution on the blackboard and desks is uneven, which has a negative impact on the students' vision and causes the occurrence of students' light source myopia; the existing double-tube lighting fixtures for classrooms are not suitable for The specific performance of audio-visual teaching is: when conducting audio-visual teaching, due to the unnecessary distribution of light on the blackboard wall, the light emitted by the projector and the light projected on the wall by the lamp are superimposed, causing students to watch the projection screen. The brightness is too strong and the eyes feel uncomfortable, but if the lighting is turned off at this time, it will cause insufficient illumination distribution on the desk, preventing students from reading or taking notes at the same time
