Incandescent lamp defect introduction

Compact fluorescent lamps sell for about 10 times the price of incandescent bulbs, but their lifetime is six times that of the latter, and for products of the same brightness, fluorescent lamps consume less than a quarter of the incandescent bulbs. With the emergence of new products, new light sources have also been born, such as LED light-emitting diodes, which are semiconductor solid-state light-emitting devices, known as the fourth-generation illumination source or green light source, which are energy-saving, environmentally friendly, long-life, small, etc. Features, the service life can reach 60,000 to 100,000 hours, more than 10 times longer than the traditional light source; electro-optical power conversion can exceed 10%, the same lighting effect is more than 80% energy saving than traditional light sources.

Humans have used incandescent bulbs for 128 years. When it comes to incandescent bulbs, people will definitely think of Edison. In fact, long before Edison, British electrical engineering engineer J. Swan began research on electric lights from the late 1940s. After nearly 30 years of hard work, Swan finally found a carbon wire suitable for filaments.
