LED light tube development

Energy and environment are major challenges facing mankind in the 21st century, so green energy conservation has become the focus of world attention. Taking lighting as an example, its electricity consumption accounts for about 20% of the total. Greatly reducing lighting electricity consumption is an important way to save energy. LED has gained unprecedented opportunities in the field of lighting with its high efficiency and energy saving characteristics.
LED light-emitting diode, also known as light emitting diode (LED for short), is a semiconductor light-emitting device that can convert electrical energy into light energy and belongs to solid-state light source. It uses solid semiconductor chips as light-emitting materials. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine, releasing excess energy and causing photon emission to produce visible light. Compared with traditional vacuum incandescent bulbs, semiconductor LED light sources have incomparable advantages. Semiconductor LEDs have an extremely long working life, which is more than 10 times that of traditional lighting fixtures, effectively reducing costs; they have low power consumption, high luminous efficiency, and energy saving, making them suitable candidates for future energy strategies; LED light sources are small in size, light in weight, and highly adaptable, providing great flexibility for design and application; since white light high-power LED light sources are solid bulbs, they do not need to be encapsulated in vacuum glass, so they are resistant to impact and collision; LED light sources are also pollution-free and mercury-free light sources.
Especially in recent years, with the improvement of LED chip technology, the reduction of prices, and the maturity of related drive circuits, the application of LED light sources in the field of lighting has become possible. In the current situation of increasing global energy tensions, some developed countries and regions in the world have implemented plans to promote the development of the LED industry. The United States, Japan and other countries and Taiwan have predicted the benefits of LED lighting. 55% of incandescent lamps and fluorescent lamps in the United States have been replaced by LEDs, which can save $35 billion in electricity bills and reduce 755 million tons of carbon dioxide emissions each year. If 100% of incandescent lamps in Japan are replaced with LEDs, the power generation of 1-2 nuclear power plants can be reduced, and more than 1 billion liters of crude oil consumption can be saved each year. 25% of incandescent lamps and 100% of fluorescent lamps in Taiwan have been replaced by LEDs, which can save 11 billion kWh of electricity every year.
The 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, which attracted worldwide attention, were both themed around green energy conservation, which brought huge historical opportunities for the development of China's LED lighting industry. According to a recent forecast released by Sinotes, a well-known domestic research company, driven by the Olympic Games and the World Expo, the scale of China's LED lighting market will grow rapidly from 4.85 billion yuan in 2007 to 9.81 billion yuan in 2010. In the context of global energy shortages and increasing environmental protection requirements, with the significant advantages of LED lighting technology such as high brightness, long service life, energy saving, and green environmental protection, along with the rapid development of LED technology, the time when LED becomes a common lighting source is getting closer and closer, and it will surely become a new lighting revolution in the history of human lighting after incandescent lamps and fluorescent lamps.
