The incandescent lamp invented by Edison has brought new light to people's lives, and now it will gradually withdraw from the market because it does not save energy. From the point of view of the promotion of various parties, energy-saving lamps seem to be the alternative, but LED bulbs have something to say: compared with incandescent lamps and energy-saving lamps, I am more energy-efficient, longer-lasting, and gradually priced. It tends to be popular. Compared with incandescent lamps: Low power consumption and longevity After testing more than 1,600 materials, Edison finally put the tungsten wire with a longer life in an incandescent lamp, so the world is bright. In the past 100 years, incandescent lamps have accompanied users around the world, but after a long period of use, people have found that such bulbs are not energy efficient and easily damaged. "Tungsten wire will be black, and then it will not be bright, and the tungsten wire is particularly easy to be blown." This is the common experience of incandescent users, they have to change the bulb frequently. Looking at the world, one-fifth of the electricity is used for lighting, showing how much power is consumed. In the past few years, European countries began to ban the use of incandescent lamps. China also issued a notice in the past few years that it will phase out incandescent lamps and plan a detailed route for the delisting of incandescent lamps: November 1, 2011 to 2012. On the 30th of the month, the transition period will be banned from importing and selling ordinary lighting incandescent lamps of 100 watts or more from October 1, 2012. From October 1, 2014, the import and sale of ordinary lighting incandescent lamps of 60 watts and above will be banned. From January 1st to September 30th, 2016 is the mid-term evaluation period. From October 1, 2016, it is forbidden to import and sell ordinary lighting incandescent lamps of 15 watts or more, or adjust according to the mid-term evaluation results. Since its implementation, it has been difficult to find ordinary lighting incandescent lamps of 100 watts or more on the market. Compared with incandescent lamps that consume a lot of power, LED bulbs that emit light by diodes are very energy-efficient, and their lifetime is ten times that of incandescent lamps. At the same time, when it is close to the incandescent lamp, the human hand will obviously feel the heat of the bulb, but the LED bulb itself does not heat up, and there is a special heat sink outside the bulb, so it will not burn the hand. Some cosmetic materials will state that women who love beauty should pay attention to indoor sun protection. Some people may be surprised that there is no need for sun protection in the room. This is because traditional light sources such as incandescent lamps contain some infrared rays and ultraviolet rays. People's skin is at risk of sunburn, and users who use LED lights do not have to worry about it. The reporter consulted with the person in charge of Philips Lighting. "LED bulbs are semiconductor-emitting devices that contain visible light." Zhang Zhenqi, manager of Philips LED light source, told reporters that this kind of visible light is a safe cold light source with low heat radiation and will not harm human skin. Compared with energy saving lamps: No heavy metal pollution is healthier In recent years, in order to save more resources, the state has been promoting energy-saving lamps as lighting tools. Energy-saving lamps reduce the waste of electricity to a certain extent, but the risks brought by them at the same time cannot be underestimated. The glass lamp of the energy-saving lamp contains a heavy metal such as an inert gas, a trace amount of mercury, and lead, and emits light by electrically activating the gas. Heavy metals such as mercury and lead are toxic substances that can cause personal injury if they accidentally break the energy-saving lamps. The reporter learned that an ordinary energy-saving lamp contains dozens of micrograms of mercury, and 1 milligram of mercury can cause fish in the pond to die. Some manufacturers have revealed that LED bulbs do not contain heavy metals and are composed of a variety of electronic components, so they do not cause harm to the human body. "LED bulbs still need to be recycled in the same way as ordinary bulbs and electronic products." Manufacturers believe that the recycling of electronic products should be gradually taken seriously. LED bulbs greatly reduce the harm to the human body, but users should still be correct. Discard them. Price misunderstanding: I think it is very expensive The price of an incandescent lamp is only a few yuan, and the good energy-saving lamp is only a dozen yuan, but the price of LED bulbs on the market is not less than tens of yuan, and some even hundreds of yuan. "The price is relatively cheap, and people who buy it will naturally have more." Mr. Zhang, who opened a hardware store in Beijing, told reporters that compared with single incandescent lamps and energy-saving lamps, the price of LED bulbs is slightly higher, and the market acceptance is not high. Currently 60 The sales of tile incandescent lamps are very good, second only to the energy-saving lamps that the country has been promoting. The reporter interviewed a customer randomly. The customer's idea was consistent with the store's opinion. He also believed that several kinds of light bulbs were placed in front of him, and he would prefer the energy-saving lamp for only 7 yuan in the store. "In fact, the price of LED bulbs is not high now." Some LED bulb manufacturers are very helpless. Zhang Zhenqi, Philips LED light source product manager, explained to reporters that consumers generally see the purchase price at that time, and the cost calculation should include the purchase of bulbs. Money and buying money. For example, he spent 40 yuan to buy an LED bulb. At the end of his life, he has used more than ten incandescent lamps with a unit price of several yuan and three energy-saving lamps with a unit price of more than ten yuan. The overall price is the same, and the LED lights are more energy-efficient. So the total cost of LED bulbs is lower. The reporter saw on Suning Tesco that the most expensive LED bulb is an LED smart bulb from Kabostone. The price is 139 yuan, the lowest is the 3 watt bulb that Hanyuan sells for 16 yuan. Compared with a few years ago, the price has dropped significantly. "This is the result of the expansion of LED chip capacity." Zhang Zhenqi told reporters that after the development of the entire industry, high cost is no longer a hindrance to the development of LED bulbs. After long-term use, the high cost performance of LED bulbs will be highlighted. Consumers should Have more knowledge. Phlizon Led Grow Light Promotion
