What 3871 includes

• Refers to the manufacture of devices that convert electrical energy into light. According to the principle of light emission, it can be divided into incandescent lamps (electric light sources that use thermal radiation to emit visible light when the filament is energized and heated to an incandescent state); gas discharge lamps (an electric light source that converts electrical energy into light through gas discharge); semiconductor lighting and other solid-state light sources(An electro-optical source that converts electrical energy into light by using a semiconductor chip as a light-emitting material).
• Including the manufacturing activities of the following electric light sources：
• Incandescent bulbs: special incandescent bulbs for scientific research and medical treatment, incandescent bulbs for trains, aircraft and ships, incandescent bulbs for motor vehicles, incandescent bulbs for general lighting, and other incandescent bulbs (low-voltage bulbs, refrigerator, microwave oven bulbs, flashlight bulbs, other unspecified incandescent bulbs);
• Fluorescent lamps: special fluorescent lamps for scientific research and medical treatment, hot cathode fluorescent lamps for trains, hot cathode fluorescent lamps for aircraft, hot cathode fluorescent lamps for ships, fluorescent lamps for general lighting (double-ended (straight tube) fluorescent lamps, ring fluorescent lamps, split single-ended fluorescent lamps, self-ballast fluorescent lamps, other fluorescent lamps for general lighting), Other fluorescent lamps;
