In today\'s economy, there are many different ways to save energy. I want to discuss LED lighting. If you take the time to read it, it will pay off a lot, but first of all, I have a little history. From the Beginning of Light-Emitter Diode（LED) When the first LED lamp was produced in 1907, it was about the size of the end of a needle. I believe inventors envision that one day we will use LED as the main artificial light source. It\'s their dream, and now it\'s becoming our reality. When the real LED lamp appeared in the mid and late 1970s, with the research and development of new technology, we can continue to move forward, so that the LED lamp in our lives more effective energy saving. When you touch a light-emitting LED bulb, there are several reasons why you should replace it with an LED: it\'s not hot, it doesn\'t emit as much heat as other bulbs do. LED lighting in your life saves energy and your water and electricity bills at the end of the year. The lifetime of light emitting diodes is 20 times longer than that of built-in bulbs. Long-term use can save you money. Ultimately, we will have no choice but to convert to energy-saving LED lights. If you combine them with solar cells, you have a very efficient light source and you are \"off the grid\". Africans live and live there illuminated by solar energy- Electric LED lights and China are reducing their environmental footprint by switching to LED lighting in their cities and lives. There are several reasons why LEDs are not so popular: the reason why they are more expensive is- However, scientists are working on cheaper alternatives, such as silicone resins, to produce the same or better results. Oversize is also a reason why it is not popular. Manufacturers will develop sizes that will fit our existing fixtures. Currently, only 10% of the world\'s people use LED lighting, but they predict that by 2020, the world\'s population using LED will reach 60%. Some cities around the world have changed street lights and traffic lights, and some large industrial plants have changed to save their huge energy bills. Advertising companies have replaced large electronic billboards with LEDs. Dental industry has been using special LED for many years. We will use LED lighting to illuminate our homes and businesses. Manufacturers\'R&D will continue to study the most cost-effective LED lighting methods. Manufacturers are making our family life more efficient in generating warmer spectra and reducing consumer production costs. In the long run, you will save money. Don\'t get caught in the process of buying LED products from overseas companies. They will make LED bulbs with cheaper components, which will reduce the life of the products. If we all try to reduce our environmental footprint, eventually LED lighting will become a part of our life one day.
