Second, choose the lamps and lanterns of the classroom, to generally require qualification certificates issued by the manufacturer, and test report to the authority of lamps and lanterns.
These are essential.
Again, the classroom health environment refers to the safety and health of the lamps and lanterns of the lamp that shield an eye or the classroom, the classroom level so that you can continue to meet the relevant requirements of the classroom environment.
The classroom level of specific parameters including desk with 300 lx, and to maintain the average intensity of illumination intensity of illumination evenness is greater than zero.
7.
And the other parameters are used as important reference items, such as the unified glare value is less than 16, color temperature in k - 3300
5500 k, color rendering index above 80, no flash frequency no harm of blue
light, etc.
And as the focus of the whole classroom teaching, the classroom blackboard lamp standards rise, such as the average illuminance is above 500 lx and intensity of illumination evenness is greater than zero.
8, etc.
Third, how to achieve the ideal classroom environment 1.
There are several types of design in general, a school classroom, several or dozens of each type of the classroom, the design is based on the area of the same type classroom size, interior wall and roof surface coating, the ground is decorated, and such as tablets, video equipment, ceiling fans, cabinets and so on facilities planning the installation position of lamps and lanterns.
2.
Key-module control lamps and lanterns is essential to the quality of the classroom, as a result, the choose and buy of the classroom of the lamp that shield an eye and blackboard lamp should at least provide mandatory product certification certificate and the distribution of lamps and lanterns photometric measurement, the harm, blue light flashing parameters such as inspection report, Ann and force of science and technology to ensure product quality of lamps and lanterns and certification provided by the type testing, inspection quality match the sample test.
All sorts of lamps and lanterns of the same kind of classroom installation specifications, quantity and installation location.
3.
Installation testing to prove the classroom in line with the health environment, collecting all kinds of classroom environment parameter data, such as testing desk surface to maintain average illuminance and intensity of illumination uniformity, writing board to maintain average illuminance and intensity of illumination uniformity, unified glare values, and parameters, such as color warm color rendering index, to do all the standards.
4.
Energy conservation and environmental protection the classroom the lamps and lanterns that shield an eye to ensure the long service life, low light failure, often to avoid the change problems such as maintenance, and more energy saving province electricity.
5 make reference point illuminance tracking inspection regularly, timely replacement, maintenance fault lamps and lanterns, ensure that the classroom in accord with the classroom environment health level.
And long-term health provided the classroom environment of service for the school.
Through the above analysis, we should have to know some misunderstanding of the classroom and the lamp that shield an eye professional classroom and the classroom blackboard lamps and
