In daily life, we will use a variety of lamps and light sources, such as incandescent lamps, energy-saving lamps, LED lamps, which can be used for direct lighting, but also can be used as a lantern light source (like chandeliers, ceiling lamps, etc.). LED lights because of the more advanced technology, energy-saving lamps low energy consumption, therefore, in the eyes of many people, incandescent lamps this "outdated" lamps are basically not within the scope of purchase.
In fact, this is not the case, taking these three lamps as an example, they actually have their own advantages and disadvantages, even if the technology is relatively backward incandescent lamps. Below, let's take stock of the advantages and disadvantages of each of the three:
Let's start with incandescent lamps:
Many people do not know, in fact, incandescent lamp is the closest to natural light source, its color temperature value is usually between 2700K and 4000K, the human eye is easier to accept. Moreover, because the grid frequency of the incandescent lamp is 50HZ, this value is much higher than the reaction speed of the human eye, and the filament has a period of inertia after being lit to cool, so in the case of grid stability, the strobe is low, and even can be ignored.
Therefore, the advantage of incandescent lamp is good color rendering (that is, it can better reduce the natural color of the object, in theory, it can be 100 percent reduction), the disadvantage is that it costs electricity, low photoelectric conversion efficiency, and short life.
It needs to be explained that the halogen lamp (that is, the halogen lamp commonly used in car lights) is actually an upgraded version of the incandescent lamp. That is, the vacuum bulb is filled with halogen gas, so as to achieve the tungsten halogen cycle between the filament and the gas, which greatly extends the life of the filament, so that it achieves the integration of high color rendering and long life.
Let's talk about energy-saving lamps:
Energy-saving lamps are CFL, it is actually a variant of fluorescent lamps, also called compact fluorescent lamps, so this article we will take the fluorescent lamps out separately to discuss. It can be made into any color temperature value, and has a high color rendering light source. Moreover, due to the glow of phosphor, the stroboscopic value is very low.
Therefore, the advantages of energy-saving lamps are high light efficiency and low energy consumption. For example, if you want to achieve the same illumination, incandescent lamps need 60W road, energy-saving lamps only need 11W can easily achieve. And regular manufacturers and brands of energy-saving lamp color rendering can reach more than 80. The disadvantage is that the fluorescent tube of the energy-saving lamp is filled with mercury vapor, and the environmental protection problem in manufacturing and recycling has not been well solved.
It is worth mentioning that energy-saving lamps are already a cost-effective light source that is relatively easy to buy on the market.
Finally, let's talk about LED lights:
Due to the different luminous principles, LED light sources completely eliminate stroboscopic and have a very high light efficiency (that is, electro-optical conversion ratio) and the potential to pursue higher light efficiency. Its advantages are small size, no strobe, no UV, high light efficiency, usually the color rendering of high-end LED products will exceed 80, and even some can reach 95, and most LED lamps have a long service life.
Disadvantages, the current market price is high (driven by interests, fake and shoddy products naturally more), and the state has not specified a clear standard for it, making the entire LED market mixed, ordinary consumers in the purchase of a certain risk.
The above three kinds of lighting source are often used in daily life, each has its own advantages and disadvantages, and there is no absolute good or bad.
However, when we buy, we must choose regular LED Lighting manufacturers, brand production of lamps, do not be cheap, save trouble, choose three factory products. The result is that the light lighting effect is not good, and the heavy one has a certain impact on physical health and personal safety.
Postscript: Lighting design is not the choice of lights, it is a technical and artistic work, if you really do not have the time and professional degree to DIY lighting design, may wish to find a lighting designer!
If your lighting requirements are just lighting, and you do not know how much luminous flux and the number of lamps you need. Here is a general article on commercial lighting that may be able to answer your question.
