Description

Eye-protection classroom lamp

Technical Field

The utility model belongs to the illumination lamps and lanterns field, concretely relates to eyeshield classroom lamp.

Background

The classroom lamp is used for lighting in places such as ordinary classrooms, laboratories, art rooms, multimedia classrooms, meeting rooms, reading rooms and the like in schools, and has the requirements of higher illumination (more than or equal to 300lx), average illumination (more than or equal to 0.7), lamp glare value (less than or equal to 16UGR) and power density (less than or equal to 9W/m2) on the operation surface in the classroom according to national or various local standards, so that the lighting requirement of normal learning of students can be met, and if the lighting requirement is not met, the vision of the students can be seriously damaged, and the harm such as myopia is caused. Along with the continuous improvement of the technological level, equipment applied to education is more and more advanced, the electrified education process is improved year by year, various eye-protecting classroom lamps are more and more applied to the general education classroom, the eye-protecting classroom lamps have the characteristics of no stroboflash, no glare, no blue light hazard, high color rendering index, moderate color temperature, excellent illumination and the like, and the optical path and the distribution of the lighting lamps in the space are adjusted through professional optical and lighting designs, so that the light distribution in the designated area in the space is uniform and is not dazzling, and the eyesight of students is protected.

At present, a large number of eye-protection classroom lamps are involved in the classroom lamps sold on the market and the published technical documents, but by comparing the prior art and the products, it can be found that the prior products aim to solve the problem of illumination of the eye-protection lamps and how to enable the eye-protection lamps to have a good function of preventing glare, and the problems are all solved well. According to the using environment of the eye-protection classroom lamp, the problems of installation and service life of the eye-protection classroom lamp are solved, but the problems in the prior art are all rarely considered.

For example, chinese patent application No. 201820181079.6 discloses an LED classroom lamp, which includes an outer housing, a lighting assembly, and a grid plate, wherein holes on the grid plate are honeycomb-shaped, so as to solve the problem that the conventional classroom lighting lamp cannot give consideration to both illumination and glare, but according to the patent document, it can be found that the position of a suspension rod relative to the outer housing is not changed, so that there is a problem that when a roof is drilled, the position of the hole must correspond to the position of a mounting hole on a mounting element arranged on the suspension rod of the classroom lamp, so that the classroom lamp can be mounted on the roof, which also requires an installer to accurately design the mounting position of the roof, thereby increasing the mounting difficulty. On the other hand, the lampshade is arranged in the outer shell, and the light-emitting element is arranged in the lampshade, but in the existing product, the lampshade is supported by adopting insulating materials such as plastics and the like, and the heat conductivity is poor, so that the released heat of the lamp is difficult to dissipate in the use process, and the service life of the lamp is shortened.

Chinese patent application No. 201820931230.3 discloses a novel LED lamp for classroom, this patent does not consider the problem of installation yet, in this patent, through setting up the LED light source on aluminium base board, make LED lamp strip, increase heat conductivility, however, LED lamp strip is usually thinner, when directly with LED lamp strip direct mount in the lamp shade, when lamps and lanterns use for a long time, the heat still is difficult to effectual effluvium to the life of classroom lamp has been reduced.
