History and Evolution of Lighting

by Sandy T. ECVV Online Marketing

In 2011, the United Kingdom and the Netherlands stoped selling incandescent. Previously, Australia, Argentina and Italy started the sale of the first of its kind in 2010. Since then, the sale of the national will to expand to the European Union, Canada, the United States. In 2017, mainland China will also stop selling incandescent, since then, the country will no longer use incandescent. More than a century ago, Edison invented the first light bulb in 1879, leading mankind to open a new bright era; more than a century later, in 2017 the incandescent lamp with 138 yeas history will be outdated. The broad stage will be given way to a new protagonist of LED lights.

 

The long history of incandescent light bulbs

90% in most of the incandescent lamp will consume energy into useless heat, less than 10% of the energy into light. Incandescent light bulbs, the traditional sense of "incandescent". 1906, GE invented a method of manufacturing lamp tungsten, and ultimately let the cheap method of manufacturing tungsten resolved, tungsten light bulb into the homes of ordinary people, and still in use. Today the majority of the light bulb, inject nitrogen, argon or krypton gas, the general life of 1000 hours. A century later, the incandescent lamp had to face withdraw the plight of the stage of history, most of the incandescent lamp will consume 90% of energy into useless heat energy, the energy will be less than 10% of the light.

 

HID lamps brighten up the darkness

Normal HID light flux is more than three times the normal light, the color temperature from 3000k to over 12000k, the application of lighting at night and street lamp. Development in the fluorescent lamp at the same time, another branch of the light bulb is also developing in 1932, high pressure mercury began to sell, this is the beginning of the development of HID lamps.

 

In 1961, GE Gilbert Ray Ling applied for a patent of the first metal halide lamp, the lamp is suitable for commercial, street and industrial lighting, three years after the 1964 Expo Show out Jijingsizuo. Then, the advent of high-pressure sodium lamp invented by GM in 1965. HID lamp family began a huge. Xenon lamp to break Edison's tungsten light-emitting principle of high pressure inert gas Xenon Xenon filled quartz tube, replace the traditional filament, mercury and carbon compounds in the two electrodes.

 

LED, the fourth-generation light source

It was noted that the high-brightness LEDs will be one of the human following the Thomas Edison invented the incandescent light bulb, the greatest invention. Into the 21st century, the new protagonist in the lighting on the stage began to surface in the LED lights. LED with its inherent characteristics, such as energy-saving, long life, vibration resistance, fast response, cold light source, can be seen everywhere in our daily life, household appliances, telephones, instrument panel lighting, car fog light, traffic lights.
