How to choose the most suitable lamps for educational lighting?
Lights are constantly evolving. From candles in the early days to light bulbs during the industrial revolution, to modern lighting nowadays, lamps and lanterns have been constantly evolving for thousands of years. In the complex lighting market, how to choose the most suitable lamps for their purposes is very difficult for the masses.
On campus, teachers and students cannot do without the important role of lights in their daily study, homework, and life. We can easily enumerate a lunch list, and can easily introduce a lot of work software to colleagues, mobile apps, but when it comes to choosing lamps, many people are "laymen".
When most people buy a lamp, they must first see how bright it is. Of course, we, who do not have professional research on lighting fixtures, rely on naked eyes for many hours. In addition to choosing its appearance, at most, it only asks about its wattage, raw materials, illuminance and so on.
Next, the editor will briefly analyze for us, what are the lamps used for educational lighting, and what are their advantages and disadvantages...
incandescent lamp
Common incandescent lamps on the market emit light by heating tungsten filaments, with simple structure and low price. But because it is heated and luminous, it will be very hot after a long time, and it is very uncomfortable. And because the electric current ran to heat up, only 3% of the light source of the incandescent lamp can be used to emit light, which consumes a lot of power.
gas discharge lamp
The most common and most widely used gas discharge lamp in daily life is the fluorescent lamp. It is used in many places such as campuses, teaching buildings, and libraries. The shortcomings of fluorescent lamps are very significant, relatively easy to appear blue, stroboscopic and other damage, long-term use of the eyes simply tired, not conducive to eye health.
LED classroom lights
In the field of education lighting, due to the low illuminance of fluorescent lamps, low color rendering index, severe glare, significant light flicker, and high color temperature, most of the fluorescent lamps are replaced by LED lamps. However, some campuses only install ordinary LED lights, which have no anti-glare function and have blue light damage. The light environment of the classroom has not been well upgraded, because the blue light damage of general LED lamps is more severe than fluorescent lamps.
