When can LED replace household incandescent lamps and fluorescent lamps? What are the technical advantages? What are the advantages and disadvantages?

Compared with traditional light sources, LED lamps save 80% energy than energy-saving lamps. It is understood that 1 5 watt household led bulbs can replace11watt energy-saving lamps, and the lighting effect of a 90-watt LED street lamp is equivalent to a 250-watt high-pressure sodium lamp. As we all know, energy-saving lamps have replaced traditional incandescent lamps, with lower energy consumption, longer life and better light efficiency. However, what is unknown is that, due to the technological needs, the tubes of energy-saving lamps contain heavy metal mercury. Once the lamp tube is damaged, mercury will enter the environment, causing harm to the environment and human body. Different from energy-saving lamps, LED lamps are not polluted by mercury, soil and groundwater, which conforms to the concept of energy saving and environmental protection.

The advantage of LED light source is its long service life, which can be used for 25,000 hours. After light decay, the brightness can still reach the light effect of traditional brand-new lamps. Moreover, household LED lamps have no stroboscopic, no radiation, no lead and no mercury.

The biggest obstacle for LED lighting to open the civilian market is higher than the price that people can afford. Wang Xiwei, assistant general manager of Jingyuan Optoelectronic Co., Ltd. once said, "At present, the biggest challenge for LED lighting popularization is price pressure, followed by the power consumption ratio per lumen (unit luminous flux) (lm/W). From wafer to packaging, various measures must be taken, such as adding red crystal powder and developing high-voltage LEDs, in order to achieve the purpose of reducing costs. " He predicted that in the future, high-voltage LED will gradually become the mainstream of the market, and substitutes for 75W and 100W lighting products will also appear one after another. The price problem that has been preventing LED lighting products from entering the general lighting field is expected to be solved in the next five years.

The media industry is discussing that LED will fly into the homes of ordinary people in the next five years. Most people in the industry said that the civil market should be considered after 20 15.

LED lighting lamps look forward to the era of "civilian price"

A 1.2m long LED tube, with a retail price near 200 yuan. The same traditional fluorescent lamp is less than 10 yuan. Although LED tubes are energy-saving and environmentally friendly, they have a long service life. Under the short-term immediate interests, consumers still choose the really cheap cost of living. The high price has become the chief culprit for LED to enter the homes of ordinary people.

Some experts have analyzed that with the maturity of technology, within three to five years, the cost of LED lighting lamps will continue to decrease, reaching the "civilian price" acceptable to ordinary consumers, that is, the price of ordinary household LED lamps will drop to 4060 yuan, which is really popular in the household field. 40-60 yuan! Will this be a reasonable price for the popularization of ordinary household LED lamps? Not only is the price high, but how many setbacks will LED household lighting encounter when it is popularized?

The blue light component of LED desk lamp is harmful to vision.

LED table lamp is a broad market for home lighting. However, not long ago, a woman was worried when choosing an LED desk lamp. She said, "If I buy a desk lamp for my son, I won't buy an LED." Is the rejection of LED lamps really so unattractive? Zhang Shanduan, deputy director of the Electric Light Source Research Institute of Fudan University, said that at present, many LEDs are not suitable for cooperation into table lamps in terms of luminous principle unless they are products of large companies and have obtained international certification. "LED lights have more blue light components, which is not conducive to vision." LED decorative lamp looks beautiful, but it is not good for eyesight as a desk lamp. The application market of table lamps needs to be developed.

Of course, the cheaper the price of civilian products, the better, but the performance can never be very high. Cheap and high performance is just a wish. Like all other products, LED lighting products are bound to be divided into various grades according to the price.

Consumers who encounter fake and shoddy products will be miserable.

LED lights are expensive, and there are 40-60 yuan LED lights on Taobao. Consumers always feel cheap, but how about the quality? Is it as good and cheap as you wish? A victim who had experienced inferior products said helplessly, "I used it once, and so did my colleagues." Brand is a better domestic manufacturer. When I installed it, I turned on the switch and flashed it, and it never turned on again. The family asked, "Is this a disposable flash? "

"An LED energy-saving lamp can achieve 50% to 80% energy-saving effect, and the 30% gap comes from the quality of the product." Shi Zeng, vice president of Ke Rui, said that many domestic manufacturers claimed to be able to make LED lamps, and their technical level was uneven, which LED to chaotic competition in the industry, which greatly affected the quality and reputation of LED lamps and weakened the confidence of users. "The development history of many new products shows that any inferior product may drag down the whole industry. Therefore, LED should pay great attention to the high-quality performance of products on the road of development. "

An LED lamp manufacturer admits that even if the business promotion can save energy by 80%, it does not mean that the quality of his LED lamp is the best. "It may save energy, but it can't meet the lighting brightness required by customers. After reaching the lighting brightness required by customers, the goal of saving energy by 80% cannot be achieved. "
