The experimental test data tells you what is the difference between incandescent lamps, energy-saving lamps and LED lamps
2022-08-05
At present, most of the electricity consumption of our country's residents has been converted into LED lamps, and only a small number of energy-saving lamps are used, and almost no incandescent lamps are used for lighting. But why is this, do you know? Today, I will tell you the reason and the result with data from experimental tests.

But why is this, do you know? Today, I will tell you the reason and the result with data from experimental tests.
When looking at data, first understand two concepts.
Color rendering index: Ra, representing the color rendering of the light source, the larger the Ra value, the better the light source can display the color of the object itself. The color rendering index of natural light in our life is 100. Under the illumination of natural light, we can feel the most comfortable, so the closer the color rendering index is to 100, the more people like it.
Light efficiency: The ratio of the total luminous flux emitted by a light source to the electrical power (watts) consumed by the light source is called the light efficiency of the light source. The higher the luminous efficiency, the greater the amount of light emitted, the higher the efficiency of converting electrical energy into a light source, and the greater the energy saving.
