Which is better for incandescent lamps, fluorescent lamps and LED lights? This problem looked very simple at that time, obviously the worst incandescent lamp, the best LED lights. However, some people recently flipped the incandescent lamp and said that “LED lights are not power -saving” and “have a long life of incandescent lamps.” Let’s talk about it today, what is the difference between these three lamps.
Some people say that LED light saving is not accurate. It should be said that LED lights are more efficient. High efficiency is not equal to power saving, just like the question of “60W LED lights and 60W incandescent lamps”, the answer is the same.
The tile of the lamp determines its power consumption. We are getting higher and higher in pursuit of brightness today, and we can’t wait to make it brighter than during the day. The LED light used by the family has a total power of more than 60W. So some people complain that “the LED light is more electricity”, because you also improve the power while changing the lamp.
The efficiency of LED lights is high, and the brightness reflected in the same power is higher. If you want the room to be as bright as day, a 60W LED light is enough. If you replace it with incandescent lamps, I am afraid it takes hundreds of watts.
Candidates, fluorescent lights (energy -saving lamps), and LED lights are all transformed into light energy. The conversion efficiency of incandescent lamps is about 15%; the fluorescent lamp is about 50%; the LED light is about 90%. The remaining power energy was wasted into thermal energy. So we see that the incandescent lamp is very hot, and the LED lights are almost not hot.
Color temperature is different
The light we pursue is actually sunlight. We call the sun “white light”, and all lighting fixtures are pursuing white light -white, which is a color temperature.
The greatness of the LED light is that it can create a variety of color temperatures we need, and the color temperature adjustment range is very wide. If you want yellow light, you can emit yellow light; if you want white light, you can emit white light; it is not impossible to want a higher color temperature.
As long as you are willing, you can buy any color temperature LED light between 2500K ~ 7500K.
The fluorescent lamp is much worse, and its color temperature is mainly concentrated at about 3000K. This kind of light is more accustomed to call it “warm white light”, which is close to white light, but it is not white enough.
The incandescent lamp can only emit yellow light, and the color temperature is around 2500K. The yellow light under this value is only a little white than the candlelight.
The color temperature has a great impact on people’s feelings. The whiter the light is, the more energetic people are; the more yellow the light, the more darker the person. So when we choose LED lights today, people will recommend that you install low -color temperature in the bedroom and install high -color temperature in the living room. Imagine that if we still have a single -colored warm incandescent lamp to this day, let alone “996” in the company. Everyone is drowsy.
Different life span
The glowing body of the incandescent lamp is the tungsten wire inside, and we can understand the tungsten wire as a rope. The tungsten wire is also fever during the process of glowing, and the heat will be lost. One day the tungsten wire was broken, and the lamps were broken. This structure is simple, so life span can be imagined -generally speaking, the theoretical life of incandescent lamps is about 1,000 hours.
The fluorescent lamp is slightly better. It is to use the internal high -voltage inert gas to power the molecule to move quickly. The theoretical life span is about 3,000 hours.
The lighting principle of LED lights is relatively complicated. We don’t need to know too much, as long as it knows its theoretical life span is enough, it is enough.
From this point of view, a LED light is not a problem for more than ten years. But some people say that their LED lights are broken after three differences. Why?
This is because LED lights cannot be directly electrode. It also needs a series of transformers, voltage voltage and other devices. These devices form a small box called “starter”. No matter how long the luminous body is, the starter is broken, and we also habitually believe that “the light is broken.”
In this regard, we have two suggestions:
1. Buy a better launcher. The lifespan of the starter is different, but the life of the high -quality promoter is not lower than the luminous body.
2. The lights are broken, don’t rush to replace the entire light. Spend a dozen dollars to buy a promoter and change it, which can solve more than 90%of the problem.
