The person who is answering your question now is a lighting company. Regarding your question, in fact, lighting companies have very little waste at present, because the current lighting is mainly LED, and LED is very mature. Let’s see The market price competition of LEDs is so fierce, which shows that the maturity of LED technology and the control of costs are quite good, so there is very little waste. For lighting, it is generally only lighting sources plus external decoration. , Lighting manufacturers do not produce decorative accessories, generally only produce light sources and even ballasts and other supporting facilities, and even some lighting factories do not even produce light sources, but all materials are purchased and assembled after designing the lighting style.
Therefore, these assembly materials are almost all purchased finished raw materials, as long as they are assembled. Scrap is already low because they remove the wasteful part of manufacturing.
