Electric light sources come in various types, each with its own unique structure. However, most share common components such as filaments, electrodes, and phosphors that emit light. The outer casing is typically made of glass, translucent ceramic tubes, or quartz, which helps contain the internal elements. Additional parts include guide wires, stems, and lamp holders, while the interior often contains gases, mercury, metals, or halides to enhance performance. Other essential components are getters, coatings, insulating materials, and adhesives that ensure durability and safety. When evaluating electric light sources, there are six main performance indicators to consider. First, light quantity characteristics, which involve total luminous flux, brightness, light intensity, ultraviolet radiation, and heat emission. Second, light color characteristics, including color appearance, color temperature, color rendering ability, chromaticity, and spectral distribution. Third, electrical characteristics, covering power consumption, voltage, current, starting behavior, and electromagnetic interference. Fourth, mechanical properties, such as size, structural design, and lamp holder compatibility. Fifth, economic factors like luminous efficiency, lifespan, cost, and energy expenses. Finally, psychological aspects, which relate to the aesthetic appeal and user comfort of the lighting product. Understanding these elements helps in choosing the right light source for different applications, whether it's for residential, commercial, or industrial use. Each component plays a role in determining how well a light source performs and how long it lasts. Additionally, considering both technical and human-centered factors ensures that lighting solutions are not only efficient but also pleasant to use in everyday environments.
