The development history of lamps
Early lamps resembled the ceramic food container "beans". The upper and lower seats are connected by pillars in the middle. Although the shape is relatively simple, the basic shape of a Chinese oil lamp is laid. After thousands of years of development, the function of the lamp has gradually changed from a single practicality to a combination of practicality and decoration. The exquisite lamps and lanterns unearthed from the tombs of the past dynasties, as well as the works handed down in the palace, are exquisite in shape and rich in decoration, reflecting the aesthetic fashion of the mainstream society at that time.
Every change affects the development of lighting companies. Due to the development of LED lighting technology, China's lighting industry has once again entered a critical period of significant changes in the industrial structure.
Modern lighting includes home lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, special lighting, etc. From the birth of electricity, the earliest incandescent light bulbs appeared in the home lighting, and later developed to fluorescent tubes, and then to energy-saving lamps, halogen lamps, tungsten halogen lamps, gas discharge lamps and LED special materials lighting, etc., all lighting fixtures are mostly It is still developed under the development of these light sources, such as from electric lamp holders to fluorescent lamp brackets to various craft lighting.
The light source of commercial lighting is also developed on the basis of incandescent lamps, such as halogen lamps, metal halide lamps, etc. The lamps are mainly spotlight and floodlight. Signs, advertisements, characteristic window and background lighting are constantly being developed. The land came into being based on development needs.
The light source of industrial lighting is mainly gas discharge lamp and fluorescent lamp, combined with other lamps and lanterns, such as waterproof, explosion-proof, dustproof and other requirements to customize, but industrial lighting needs to be cautious, especially in the selection of light sources and lamps. Pay attention to the fact that the color and fabric texture produced by clothing are not the same under different light sources. The choice of lamps mainly considers reflectivity, illuminance, maintenance coefficient, etc. At present, most domestic enterprises still do not pay much attention to it, only In some foreign-funded companies, a comparison may be made.
As a daily consumable, the lighting appliance industry has undergone earth-shaking evolution with the emergence of new light sources such as fluorescent lamps, energy-saving lamps, and LEDs with the progress of my country's economy and society. All efforts are made towards more energy-saving, greener and environmentally friendly perspectives. The abundance and multiple choices of light sources have also opened a new chapter in the lighting industry. With the acceleration of China's urbanization process, urban squares, traffic roads, newly built communities, home decoration, shopping malls and office buildings all need the decoration of lamps and lanterns. The demand for lighting products in urban construction will continue to increase.
The choice of lamps for road lighting and landscape lighting is completely different. Dont think that just lighting is enough. Road lighting cannot blindly pursue aesthetics and ignore the safety and fog permeability. The choice of landscape lighting lamps and light sources must be fully considered. Energy-saving and beautiful, because landscape lighting does not need such high illuminance, just create a lighting feature.
