How to choose the right lighting for the classroom
With the continuous increase in the myopia rate of students, many places have begun to choose to install professional classroom lighting equipment to reduce the chance of myopia. It is precisely because of the increasing use that there are more and more specifications and models of lighting fixtures on the market, and the quality and price are also uneven. Therefore, it is a very painful thing for many consumers to choose an energy-saving and eye-protecting classroom lighting in this situation. In this case, how should we choose a product that suits us? Let's take a look. .
Light source: The straight tube fluorescent classroom lamp using rare earth tricolor phosphor has the characteristics of good color rendering, high luminous efficiency, and long service life, which can easily meet the requirements of color rendering, illuminance level and energy saving. Ordinary classrooms can use T8 straight tube fluorescent lamps, and if possible, T5 straight tube fluorescent lamps can be used to improve the lighting quality, which is more conducive to environmental protection and meets energy-saving requirements.
For the choice of LED classroom eye protection, how should I choose?
1. Normal classrooms should not use coverless direct lighting and box-type fluorescent lights. It is advisable to choose an open lighting method with a certain protection angle and an efficiency of not less than 75%.
2. If there are requirements or conditions, lamps with grilles (gratings) or with diffuser can be used, and the efficiency of the lamps is not less than 60%.
3. If the classroom space is large and the ceiling reflectance is high, a suspended indirect or semi-indirect lighting LED classroom eye protection lamp can be used. In this way, in addition to downward lighting, more light will be projected onto the ceiling to form indirect lighting and create a more comfortable light environment. If the classroom has a ceiling, recessed or ceiling lights are usually used.
4. It is not suitable to use high-brightness or full-mirror control covers (such as grille, grille, etc.). Low-brightness, diffuse reflection or semi-mirror control covers (such as grille, grille, etc.) should be used.
When choosing high-quality products, the probability of choosing myopia products should be reduced. Although lighting in the market can be seen as uneven, we can choose from light sources and lamps when choosing. Of course, when we choose, we should try our best to choose high-quality and low-cost lamps. Don't just consider the price of the lamps, and don't buy low-quality products for cheap. This is not only useless, but also more likely to hurt the eyes, increasing the cost of buying lamps.
