HD LED display screen modules.The significance of LED lighting

　　Residential lighting is of great significance for human life. It not only ensures the normal functioning of people's daily life, cultural entertainment, and household chores, but also integrates the beautiful shape, color, pattern, and artistic effect of lighting fixtures with indoor decoration into a unified entity, bringing a peaceful and comfortable atmosphere to family life. Just like public buildings, indoor lighting has practicality and decoration. How to handle the relationship between the two can play a more effective role in indoor decoration.

　　The working field of an incandescent lamp is the current flowing through the filament, and through the thermal effect of the current, the incandescent lamp emits continuous visible and infrared light. Due to the high filament temperature during operation, 80% of the energy is converted into heat and wasted in the form of infrared radiation, ranging from 12 to 24 lumens per watt. Due to the high temperature of the filament and rapid evaporation, its lifespan has been greatly reduced, around 1000 hours. Although incandescent lamps react quickly, they are inefficient, consume high electricity, have a short lifespan, and are prone to breakage.

　　Fluorescent lamps mainly heat the filament of the lamp tube through a ballast. At a temperature of approximately 1160K, the filament begins to emit electrons (because some electronic powder is coated on the filament), and operates using the principle of gas discharge, emitting 253.7nm ultraviolet light, which excites the fluorescent powder to emit light. 50-70 lumens/watt, with a light source lifespan of 5000-10000 hours and a decay rate of 10-20%.
