When selecting the classroom dedicated lamp need what to key reference data

We used in the classroom light if you want to have good effect, we should not only ensure the choice of lamps and lanterns is in line with the use of the environment, its design layout should also be scientific and reasonable. So that students learn in the classroom will not only feel eye fatigue, can protect the eyes. So we need to reference when choosing the classroom dedicated lamp which key data? Now as to find out together! Efficiency: the whole classroom dedicated light the luminous flux of lamps and lanterns made by all the luminous flux emitted by percentage, we can use to see whether the efficiency of energy saving lamps and lanterns. In general, the higher the efficiency of lamps and lanterns, can the more effective use of light flux; Instead, the lower efficiency, the lower its energy utilization. Light distribution shape: general small grille lamps and lanterns is cosine light distribution, the luminous flux is concentrated in the light part of the lamps and lanterns, toward the light intensity is very low, beside want to achieve the ideal effect, but increasing the number of lamps and lanterns use only. There is also a larger grille lamps and lanterns, the light distribution shape of bat wings light distribution, this kind of lamps and lanterns of light on the 45 ° direction, can make the intensity of illumination uniformity in large area to achieve high level. Glare quality grades: small grille lamps and lanterns can be used in the 500 lx acuities were generally illumination acuities were 1000 lx, reached A level, and large grille lamps and lanterns is mostly in the 300 lx or less use of illuminance acuities were 500 lx, reached A level, thus, small grille lamps and lanterns of glare quality level is generally better than big grille lamps and lanterns. Classroom dedicated lamp is commonly used lamps and lanterns has two big grille lamps and lanterns and small grille lamps and lanterns, through comparing the above parameters is both have their own unique advantages, therefore, we can according to the practical use situation to choose the appropriate lamps and lanterns. Above is the 'select classroom dedicated lamp need what to key reference data' detailed introduction, hope to help you!
