On October 21, 1879, the inventor Edison built the world's first practical incandescent carbon filament lamp based on the research and practice of his predecessors, using the improved carbonization method. The era of lighting.

In 1938, Iman, a scientist at General Electric in the United States, applied phosphor in a glass tube and filled it with mercury to create a fluorescent lamp that was similar in light to sunlight. It has changed the shortcomings of traditional electric lamps, such as power consumption and low illumination, making electric lighting enter the energy-saving era for the first time. Because the fluorescent lamp is a shiny glass tube, it is called "light pipe" by the world.

As a new lighting fixture, the light pipe quickly entered the home, school, factory, hospital after the Second World War... It became one of the essential lighting tools for human beings.

At the end of the last century, Hong Kong inventor Wu Tuoshan spent nearly 10 years under the influence of the global environment that spared no effort to save energy. He developed a self-ballasted constant temperature energy saving that is 50% more energy efficient and 20% more luminous than ordinary light pipes. The lamp tube has made the energy-saving step of the light pipe take a big step forward again, setting a new milestone in the history of energy-saving lighting. Since the ballast constant temperature energy-saving lamps have filled the gaps in international and domestic technology, they have played an important role in saving energy and energy. They have won the heavyweight awards such as the China International Patent and Brand Expo Special Gold Award.

Wu Tuoshan said that the persistent idea of ​​inventing energy-saving light pipes originally originated from a dream of his teenager.
