Philips has spanned three centuries. The history of this world-famous enterprise can be traced back to 189 1. Dutch mechanical engineers began to produce carbon filament light sources in a former deerskin factory in Eindhoven, the Netherlands. Among his earliest major customers, some early power companies included the supply of light sources in their energy supply contracts. These companies put forward higher standards for product quality, which made young Philips strictly monitored in terms of quality from the beginning. 1908 is the first year that Philips entered the world market and began to produce tungsten filament bulbs. 19 13 tungsten filament gas-filled "half-watt" lamp was put on the market, followed by the smaller "Arga" light source in 19 15. At that time, Philips' slogan was "We have a light source suitable for every application". 19 14 The company set up a research room to study physical and chemical phenomena and promote product innovation. This can be regarded as a symbol of its product innovation, because in the following year, Philips has expanded its own strength, and its business has expanded to various products such as car lights, searchlights and theater lighting. Before World War I, Philips entered the American and French markets successively, and 19 19 entered the Belgian market. By the 1920s, Philips had become one of the most influential manufacturers of carbon filament lamps in Europe. From this era on, Philips began to protect its inventions with patents, and took absorbing X-ray radiation and radio as a new field of struggle for the company, which marked the diversification of Philips products. 19 18, Philips produced the first medical X-ray tube. From 65438 to 0925, Philips entered the initial attempt of TV development. From 65438 to 0927, Philips began to produce radios. Only one year later, Philips not only made the output of radios reach 1 100 million, but also began to produce medical X-ray equipment in the United States, thus entering the field of medical equipment.
