The lighting environment is not ideal, which is one of the factors that affect the visual health and eye comfort of primary and middle school students. In particular, classroom reflections, glare, rainy days or dim winter light, etc., the educational lighting environment that does not meet the standard needs to be improved urgently, and the improvement of the classroom lighting environment has attracted the attention of all walks of life. Students ’parents are concerned about whether the classroom lighting environment is conducive to students’ visual health. Schools and competent departments hope to improve classroom lighting and obtain a certificate from a qualified certification testing agency. Specific requirements: to prove that each classroom in the school is in accordance with a healthy lighting environment Requirements; to prove that the improvement of classroom lighting quality can meet the requirements of healthy lighting environment for a long time.
If a full set of lighting testing is carried out for each classroom, the testing workload is large and the cost is high; if it is necessary to verify that the lighting quality of the classroom can meet the requirements for a long time, it is necessary to ensure the life and maintenance of the classroom lighting fixtures and follow-up testing. In order to meet the above requirements for compliance certification, an attempt was made to design a voluntary certification system to reduce testing samples and workload, improve testing efficiency, expand the coverage of certification, and reduce the cost of testing or certification.
Classroom health lighting environment voluntary certification plans to adopt the fifth international common certification scheme : initial testing + inspection + post-certification supervision. Post-certification supervision includes: supervision and inspection + inspection. The following is a discussion on the control requirements and logic of the main links of classroom health lighting environment certification.
1. Series (certification unit) division
The samples of classroom lighting testing are classrooms. Generally, a school has several types of classrooms, and each type has several or dozens of classrooms. The area, length, width, and height of the same type of classroom are basically the same, and the interior walls and the top surface are the same. The coating and floor decoration are consistent, and the same writing board, video equipment, lighting fixtures, ceiling fans, cabinets, etc. are installed at the same location. If each type of classroom is summarized as a certification unit, a representative classroom in that type of classroom is selected for lighting inspection, and at the same time, the size, decoration, equipment and installation location of other classrooms are checked to confirm with the inspected classroom Consistent, then the test results of the classroom lighting drawn can represent the lighting test results of several other classrooms or dozens of classrooms of the same type. It is possible to cover the certification unit without performing lighting tests on each classroom of the same type Conformity evaluation of each classroom can greatly reduce the workload of testing.
2. Control of key parts
Lighting fixtures are critical to the quality of classroom lighting. Therefore, the purchase of lighting fixtures should provide at least a compulsory product certification certificate and a test report of parameters such as the photometric distribution of the lamp distribution, blue light hazard, and lighting flicker, or a voluntary certification certificate for classroom lighting products And, the lamp manufacturer should ensure that the quality of the lamp products provided is consistent with the quality of the samples of the certification type test and the inspection test. The model specifications, quantity and installation positions of various lighting fixtures installed in the same type of classroom should be completely the same.
3. Initial inspection
In order to prove that the classroom lighting conforms to the healthy lighting environment, collect advanced indicators of various classroom lighting environment quality standards, test the desk desktop to maintain average illuminance and illuminance uniformity, writing board to maintain average illuminance and illuminance uniformity, uniform glare value, lighting power density, On-site color temperature and color rendering index and other parameters, issued a compliance test report.
4. Initial inspection
Check the quality assurance ability of the classroom lighting engineering (installation) company, check the job responsibilities, training and qualifications of various personnel, check the design of the lighting plan, check the supplier evaluation of key components and purchase acceptance control documents and implementation records, check the classroom lighting Lamp installation, use and maintenance control requirements and implementation records, routine inspection regulations and inspection records after lamp installation, etc.
Go to the school site to inspect other classrooms covered by the same series (certification unit), check the configuration and installation locations of classroom lamps and other equipment, the consistency of interior decoration, check the firmness of lamps and ceiling fans, and perform compliance evaluation .
5. Issuing a certificate
The initial inspection is qualified, the initial inspection of the engineering (installation) company’s quality assurance ability meets the requirements, or the quality assurance ability meets the requirements after taking corrective measures for non-conformances. After the certification body reviews, the classroom health lighting environment voluntary certification is issued. Classroom logo Classroom health lighting environment certification mark, valid for five years.
6. Post-certification supervision
In order to prove that the quality of classroom lighting can meet the requirements of a healthy lighting environment for a long time, you can accept and adopt the test report of the reliability of the lamps (light maintenance life), but the more intuitive verification method is the use of certification supervision and inspection. The quality assurance ability of the witness shall be supervised and inspected. Check the maintenance and repair records of classroom lighting fixtures. If classroom lighting fixtures need to be repaired or replaced, lamps or parts of the same model specification must be replaced; check the classroom lighting self-examination (tracking inspection) records; go to the school site for classroom lighting supervision and inspection. In the school classrooms covered by the same kind of classroom health lighting environment certification certificate, according to the proportion of the certificate held by the certificate holder, the classroom lighting environment covered by the certification certificate is sampled to avoid repeated sampling of the same classroom sample for testing and evaluation.
7. Certificate validity period
After the classroom health lighting environment certification certificate is issued, the certificate holder or the school should do regular maintenance of the lamps and lanterns, if they are found to be abnormal or damaged, they should be repaired or replaced in time, and the reference point illumination tracking inspection should be done regularly to understand the classroom lighting environment status in real time. Once the supervision and inspection finds that the classroom lighting environment maintenance is not normal and the classroom lighting supervision and testing results do not meet the requirements of healthy lighting environment, the licensee should take corrective measures for rectification. If the rectification cannot be completed within the specified period, the certification body has the right to suspend or revoke For the certification certificate, the certificate holder shall be responsible for removing the certification mark of the classroom healthy lighting environment pasted in the school classroom.
Classroom health lighting environment certification certificate is valid for five years. If, according to the analysis of annual classroom lighting supervision and testing and follow-up inspection data, classroom lighting level attenuation is very small, the certificate holder can apply to extend the validity period of the certification certificate.
