The advantages and disadvantages of incandescent lamps
The so-called incandescent lamp means that after electrification heats our filament into an incandescent state, it is a visible electric light source emitted by the incandescent lamp through the use of heat radiation. The incandescent lamp has good condensing properties and light color Quite good, they are commonly used lighting fixtures at the moment. Compared with other light sources, incandescent lamps have their own advantages and disadvantages. Many people don't know much about them. What are the advantages and disadvantages of incandescent lamps? What are the tips for choosing incandescent lamps? Let's follow Benwei light to get to know it.
The advantages and disadvantages of incandescent lamps:
1. The advantages of incandescent lamps:
1. The light color of the incandescent lamp is very good, its light color is almost close to the color of sunlight, and it has good color rendering.
2. There are various types of incandescent lamps, especially the color series products, which have great versatility.
3. The incandescent lamp is cheap and the light source is small.
4. There are various forms of incandescent lamps, including directional, diffuse, and scattering forms.
5. The use of incandescent lamps can enhance the three-dimensional sense of objects under certain circumstances.
2. Disadvantages of incandescent lamps:
Incandescent lamp is a kind of lamp that has been used for a long time. With the continuous innovation and advancement of science and technology, many new light sources are gradually being developed. For example, our LED light-emitting diodes are a typical new light source. The representative of, has the characteristics of environmental protection, energy saving, long service life, and the lighting effect is obviously better than that of incandescent lamps. Therefore, this is also a major defect of incandescent lamps.
Incandescent lamp
The above is a brief introduction about the advantages and disadvantages of incandescent lamps. I believe that after the above introduction, everyone will have a better understanding of incandescent lamps. Of course, there are many incandescent lamps on the market today. If you want to choose high-quality incandescent lamps, You have to master certain skills. Let's take a look at the following introduction to the purchase skills of incandescent lamps:
Tips for purchasing incandescent lamps:
1. Check the lights:
When buying an incandescent lamp, you can observe its luminescence with your eyes. If the light emitted is particularly bright, it means that the quality of the incandescent lamp is not good, because the high-quality incandescent lamp usually emits softer light, and its color light is the best. Close to the color of sunlight.
2. Power consumption:
You can try to light a light bulb to observe its lighting efficiency and power consumption. Generally speaking, only a small part of the power it consumes, that is, only 12%-18% can be converted into light energy, and the rest is It is lost in the form of heat, and as for the lighting time, the service life of this kind of electric lamp usually does not exceed 1000h.
3. Object color:
Because the light emitted by the incandescent lamp is full-color light, but the composition ratio of the various color lights is determined by the luminescent material (tungsten) and the temperature. The imbalance of the ratio leads to the color cast of the light, so the color of the object under the incandescent lamp is not real enough .
