Lamps in modern lamps

1809, the British chemist David invented the arc lamp, and mankind entered the era of using electric lamps for lighting. 1879, the California theater first used arc light. 1906, Edison invented the household tungsten light bulb. Since then, incandescent lamps, fluorescent lamps, energy-saving lamps, neon lights and various high-tech lamps invented by modern high-tech have mushroomed on the lighting stage, greatly facilitating people's production and life.

Edison's greatest contribution to electric lamps was the design of filament. He tried more than 6,000 kinds of alternative filament in two years, and spent $40,000 on as many as 1200 experiments. After testing various materials all over the world, Edison found that platinum was the most effective. However, this material is very expensive, and its efficiency is limited as a practical filament. Finally, Edison tried carbonized cotton thread. 1879 10 19 On Sunday evening, Edison and his assistant electrified cotton silk and observed it day and night in turn. After more than 40 hours, the cotton thread was still shining, and Edison knew that he had solved the problem.

The sales of light bulbs began at 1880, and Edison lighting system first appeared in London as early as 1882 on the Holborn viaduct. The era of general electric lighting with centralized power supply in cities began at Pierre Street Station in new york,1September 4, 882. In the face of a reporter's question, Edison "I have fulfilled my promise".
