The first thing to say is: Although LED has a large-scale application in the lighting field and is also an important direction in the future, it does not mean that LED can dominate the world. Many newcomers who are determined to do lighting design are misled, thinking that LED is the available light source and the whole of lighting. This is very unfavorable to their growth. Because only by in-depth research on the light distribution of lamps with light sources such as fluorescent lamps and gas discharge lamps can we have a deep understanding of the essence of lighting. LED cannot replace traditional light sources in many occasions. The threshold of lighting design is very low, so many people from related majors or completely unrelated majors join in. Without professional training, coupled with the wrong guidance of a master who knows little, he will go astray unconsciously. We believe that lighting design has five artistic conceptions. The poor, garbage-like design is to close your eyes and place the lights, regardless of the final effect, investment, power consumption, etc. Their method is to put the lights on the places where the lights can be placed, and illuminate the places that can be illuminated. The project site is like a lighting expo. Although this kind of design is rare now, it has not been completely eliminated. The interior of the home store is better than the garbage design. It is a mediocre design, just like the unchanging burger and fries and Cola in the fast food restaurant, which is infinitely copied. This kind of design simply illuminates the building, with the same taste or even no taste at all. It is enough to take a look at it, and there is no desire to take a second look at it. This kind of design has neither artistry nor waste of electricity. The passing line of McDonald's internal design should be at least a surprising design with innovation, combining the function, shape and characteristics of the building. The integration with the surrounding environment enables viewers to experience the design concept of the building and the aesthetic feeling completely different from that of the day.
