The fourth-generation lighting fixtures of Chinese people may be lighting

In the past hundred years, the speed of mankind's updating of lighting fixtures has been accelerating. It took nearly 100 years from the incandescent lamps of the last century to the energy-saving lamps of today. In the past ten years, the fourth generation of lighting fixtures has begun to take shape. The National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Finance are pushing for more energy-saving and longer-lasting LED lights. First, let them replace the old lamps in public places such as roads, squares, and stadiums, and then enter the family. For a time, domestic companies that make LED lamps swarmed to compete for business opportunities. Is it true that the fourth-generation light source for humans can only be LEDs? In fact, the lighting factory is giving people a second choice. What they like is lighting. Lighting is not a new thing. Although lighting sources have been around for many years, they are still hard to find in life. When lit, the lamp will emit electromagnetic radiation which is a fatal weakness. Although it has been proven that it will not affect human health, it is certain that electromagnetic waves affect mobile phone signals. Because the light-emitting principle is more complicated, and the model of a product with a larger body shape is a single shape, it is really not flattering, so it has not entered the home improvement market. It is also the reason why lighting is rarely seen. Mr. Zhang from the lighting factory said that the brand-new lighting they made can be low-power, small cannon-shaped and even used for home lighting, and they are no different from incandescent lamps. By overcoming two major weaknesses, compared with LED lamps, the advantages of lighting have emerged: LED lamps are expensive, and an outdoor lighting LED lamp with a power of 50 watts can be sold for a few hundred yuan more, but the price of lighting can be reduced. Control within 200 yuan. The LED lamp is a light-emitting surface, the light is directed in a fixed direction, and can only illuminate the range under a certain angle, while the incandescent lamp is a round ball, which can emit light 360 degrees, and there is no blind area under the lamp in a certain range. Like the incandescent lamp, the lighting can be made into a spherical bulb that emits light from all angles. A lamp with a power of 10 watts, whose brightness is roughly equivalent to a 60 watt incandescent lamp, can become the main force of household lighting. Its price is 80 yuan per lamp, which is not only much higher than incandescent lamps, but also several times more expensive than energy-saving lamps. Mr. Zhang said that the cost cannot be calculated like this. A lamp can be bright for 60,000 hours. If it is used for 6 hours a day, it can serve the family for more than 27 years. In this way, most people can change the light bulb twice in a lifetime.
