Portable Explosion-proof Searchlight Ocean King with incandescent defect analysis

 Portable Explosion-proof Searchlight Ocean King fluorescent lamps are incandescent bulbs cost about 10 times, but the life is 6 times the latter, and the same brightness, fluorescent tubes, incandescent bulbs consume less than a quarter. With the continual emergence of new products, new light has been born, such as LED light-emitting diode, is a semiconductor solid light emitting device, called the fourth generation light source or green light, energy saving, environmental protection, long life, small size characteristics, service life of up to 60,000 to 100,000 hours, longer life than conventional light sources more than 10 times; electro-optical power conversion close to 100%, the same lighting effects than traditional energy sources more than 80%. Human use of incandescent bulbs have been 128 years of history. Lift the incandescent light bulb, one must think of Edison. In fact long before Edison's incandescent lamp, the British electrical engineer skills Swan () from the late 1940s began to study lamp. After nearly 30 years of efforts, Swann finally found suitable for making carbon-filament yarn. December 18, 1878, Swann's first successful trial of incandescent bulbs. Shortly thereafter, he was still on the Newcastle Chemical Society, show off his carbon filament light bulbs. And when his experimental reports about the incandescent lamp post in the United States, also with direct assistance to Edison. Edison is different, Swann after the invention of the incandescent lamp, until 1880, before going to apply for a patent; until 1881 was officially put into operation. And after the lamp operation, as he failed to establish the appropriate power stations and transmission networks like Edison. This allows Edison to come from behind, it has become recognized as the inventor of the incandescent lamp.
