In some poor rural areas, many rural households still use incandescent lamps. According to experts' estimates, if a high-quality energy-saving lamp with a power of 11 watts replaces a 60-watt incandescent lamp, it will not only reduce power consumption by 80%, but also increase brightness by 20%-30%. The light-emitting diode LED made of semiconductor material is further advanced in technology, and the luminous efficiency of the white light-emitting tube has reached the level of the fluorescent lamp, even reaching the level of the sodium lamp.
Semiconductor light source energy saving, long life, safety, environmental protection, flicker resistance, variety of colors, convenient control and many other advantages, will replace the traditional light source to trigger another revolution in the lighting industry.
LED energy saving lamp price is too high
Although the LED energy-saving lamps have many advantages, the author found in the interview that due to the price and other reasons, consumers are still difficult to accept, and even many people have not heard of LED energy-saving lamps.
The most sold here is still incandescent lamps, followed by energy-saving lamps of 10 yuan and 15 yuan. LED energy-saving lamps, we have not heard of it. Pingkang Road, a salesman who sells lamps and lanterns told the author.
The owner of the shop, Wang, told the author that their energy-saving lamps are selling well, but those who come to buy energy-saving lamps are generally younger and have a certain culture. They are less likely to buy from rural areas because they don’t have much energy-saving lamps. To understanding.
The author asked Wang, have you ever heard of LED energy-saving lamps? Wang said that he heard it, but he did not have the goods in the store.
Wang told the author that at present, the promotion of energy-saving lamps is not very optimistic. The general public is even more difficult to accept energy-saving lamps, let alone LED energy-saving lamps. The biggest reason is that the price is high.
LED energy-saving lamps have good prospects
Due to reasons such as light efficiency and cost, LED energy-saving lamps are currently unable to compete with traditional high-efficiency light sources in large-area white floodlighting, but have advantages that are difficult to compare with traditional light sources in low-power lighting, local lighting, and safety lighting. .
Taking street lamps as an example, street lamps are mainly used to illuminate the road surface and belong to local lighting. Now, their companies are making useful explorations to make LED energy-saving street lamps more practical.
To do a good job of LED energy-saving street lamps, we must first choose a suitable light-emitting tube. In general, LED energy-saving street lamps can be used with either low-power LEDs or high-power LEDs. However, practice has proved that although the low-power LED has the advantage of low cost of the light-emitting device, its light decay is faster than that of the high-power light-emitting tube, and the number of tubes used is too large, the assembly is troublesome, and comprehensive consideration is made to select a high-power light-emitting tube. More reasonable.
Compared with traditional lamps, LED energy-saving lamps have several advantages. First, the small size of the LED is basically a small chip that is encapsulated in epoxy resin, so it is very small and very light. Second, the power consumption is low. Generally speaking, the working voltage of the LED is 2-3.6V. The operating current is 0.02-0.03A. That is to say, it consumes no more than 0.1W. Third, the service life is long. Under the correct current and voltage, the service life of the LED can reach 100,000 hours. There is also environmental protection. LEDs are made of non-toxic materials. Unlike mercury-containing fluorescent lamps, they can be polluted and LEDs can be recycled. In addition, it is high brightness, low heat and durable.
All of the above, LED energy-saving lamps are in line with the current policy of energy conservation and environmental protection advocated by the government. From this point of view, the prospect of LED energy-saving lamps is bright, and it is believed that in the near future, it will be accepted by consumers and enter the homes of civilians.
