Lamps are very common, and lamps are a more common application of electricity.

It is said that in the early days, people's more important application of electricity was not electricity to make things turn, but electricity to make things light up.

Of course, before electric lights, people still have to illuminate. Earlier, people used torches, followed by candles, and then kerosene lamps. After our 70s, the era of kerosene lighting is still experienced. At that time, it was not easy to buy some kerosene with a ticket.

Well, since electricity has been available, people have discovered that electricity is the better way to illuminate lamps. Today we are talking about three kinds of lamps-incandescent lamps, energy-saving lamps, and LED lamps.

1. Incandescent lamp

Here is a word for popular science, color rendering. What is color rendering is that what is originally red is still red when illuminated by a light source. If the color rendering is not good, it looks very real. For example, the front light of my mirror uses LED lights, the color rendering is very poor, and people look pale.

Summary: Although incandescent lamps are cheap and have good color rendering, they consume a lot of power and have a short lifespan. Most of the electric energy is used for heating, and their performance is far lower than that of the new generation of new light sources. They have been asked to gradually withdraw from the market.

2. Fluorescent lamp

Summary: Thanks to green lighting, we have vigorously promoted the use of fluorescent lamps. Therefore, China is currently the country with a high degree of popularity of fluorescent lamps in the world. However, as people pay more and more attention to health and environmental protection, the harm caused by fluorescent lamps is increasingly being caused by people. Criticized.

Pay special attention to the fact that the three primary colors must be selected for the lamps starting with T now. . .

At present, there are many replacement LED tubes, and the price is very low. You can consider gradually replacing the original fluorescent tubes, especially those used in the lamp trough. But you should still pay special attention to the blue light hazards of LED products (don't buy dazzling blue dazzling blue) and glare (don't buy the ones that feel particularly dazzling when they are normally installed on the ceiling).

Three, energy-saving lamps

The greater advantage of energy-saving lamps is the light efficiency ratio, that is, energy-saving, but there are some shortcomings, perhaps everyone usually does not pay attention.

Summary: Very popular, very popular, very popular! Energy-saving lamps bring a lot of convenience to our lives, but it also brings a lot of problems: mercury pollution, stroboscopic and electromagnetic radiation. Visual inspection will be replaced by LED products.

Four: LED lights

Some people may ask, are there many so-called LED eye protection lights on the market reliable?

Tell you, no matter how you protect your eyes, it is just a gimmick. At present, the less harmful ones are the traditional incandescent lamps. Why? Because the incandescent lamp has no stroboscopic, no blue light, good color rendering! It's just that incandescent lamps generate a lot of heat, consume power, and their lifespan is really average!
