How to carry out acceptance inspection of school classroom lighting reform
Recently, the China Quality Certification Center issued a report to sort out the results of the survey on the status of classroom lighting carried out by provinces and cities, and found that the problem of poor light environment in classrooms is more serious, and the problems are concentrated in the following aspects:
The lack of technical basis for classroom lighting design or supervision. The "Hygienic Standard for Daylighting and Lighting of Classrooms in Primary and Secondary Schools" (GB 7793-2010) only specifies the requirements for the use of fluorescent lamps as classroom lighting. However, a large number of LED lamps on the market are currently used in classroom lighting, and there is no need for LED lamps. Classroom lighting environment evaluation standard.
The lighting design is unreasonable. The highlight is in the design of the blackboard lamp. The light distribution method of the blackboard lamp is not designed properly, and the installation position is unreasonable, resulting in obvious unevenness of brightness on the blackboard surface and poor uniformity of illumination. At present, many schools adopt multimedia teaching. Due to the unreasonable design of blackboard lamps, the illumination and uniformity of the blackboard surface in the multimedia screen area are low. The installation design of classroom lights in some classrooms is unreasonable, resulting in low illuminance or poor uniformity of the classroom desktop.
underestimate the color temperature and color rendering index and other parameters. Due to the lack of professional guidance, schools have a strong sense of improving the brightness of classroom lighting and reducing lighting power consumption, but they do not pay much attention to important parameters related to lighting quality such as color temperature and color rendering index. Under normal circumstances, the color temperature of classroom lamps should not be too high, and art classrooms should use high color rendering lamps.
The lighting equipment is aging and lacks regular maintenance. Untimely replacement or unreasonable maintenance results in low level of illuminance or low uniformity of illuminance on the desktop in the classroom.
As classroom lighting renovations are being carried out across the country, relevant engineering acceptance tests are also essential. Pay attention to the acceptance. The acceptance test items must be complete. The test should be carried out without the influence of natural light and other non-tested light sources. Should meet the requirements of the national standard GB/T 5700.
In the certification of high-quality lighting environment for classrooms, firstly, classroom lamps are required to be of good quality; secondly, enterprises are required to carry out preliminary field research and design, select appropriate lamps and reasonable lighting methods; and, require enterprises to strictly follow the design The construction of the scheme ensures that the site meets the requirements of the high-quality classroom lighting environment; it also requires regular maintenance of the classroom lamps to continue to maintain the quality of the classroom lighting environment.
In addition, how to improve the lighting environment of the classroom? It is recommended to start with the following aspects:
attaches great importance to the quality of classroom lighting. Lamps are the key to determining the lighting effect of the classroom. Only by controlling the quality of the lamps can the quality be guaranteed from the source. Classroom lamps must meet electrical and mechanical safety requirements, electromagnetic compatibility characteristics, and electrical, optical, color, anti-glare, life, and environmental performance requirements.
attaches great importance to preliminary research and design. The actual situation of the classroom is very different. Before installing the lamps and lanterns, the site conditions should be fully investigated, the appropriate lamps should be selected according to the site conditions and a reasonable lighting plan can be formulated, which can be verified by simulation, etc., after the design plan achieves satisfactory results, then strict Carry out construction and installation according to the plan.
attaches great importance to the daily maintenance of lamps and lanterns. After the lamp is installed, perform maintenance 1-2 times a year to keep the surface of the lamp clean. If the light source is damaged or the lamp is seriously decayed, it should be replaced in time. When replacing, be sure to maintain the consistency of the lamp specifications.
