With the increasing mainstream of energy conservation in recent years, countries are actively promoting energy-saving development. In the field of lighting, their respective incandescent lamp elimination plans have been issued to further promote LED lighting, and the light source replacement will be fully opened in 2014. Due to the large power consumption and short service life of incandescent lamps, the performance is far lower than that of the new generation of new light sources. In order to save energy, protect the environment and protect the environment, incandescent lamps have been replaced by some green light sources and are required to gradually withdraw from the market. some countries have banned the production and sale of incandescent lamps. Countries or regions have formulated incandescent lamp elimination plans, and the United States has gradually stopped using incandescent lamps since December 2007. The US federal standard is carried out in two phases, from 2012 to 2014, prohibiting 100 watts of lamps. Most incandescent bulbs will be banned from sale in the US market in 2014. The 2007 Energy Independence and Safety Act stipulates that from January 2012 to January 2014, the United States will phase out 40 W, 60 W, 75W and 100W incandescent bulbs and replace them with energy-saving bulbs. In Asia, South Korea, Thailand, and the Philippines, measures have also been taken to promote the use of energy-saving bulbs instead of incandescent bulbs. For example, Japan announced in September 21, 2007 that it would cooperate with local retailers, such as convenience stores, supermarkets and electrical appliances stores to promote the use of fluorescent lamps, and called on citizens to switch from incandescent lamps to energy-efficient fluorescent lamps. As the above-mentioned countries began to completely ban incandescent lamps, LED lamps gradually entered the lighting market, which undoubtedly promoted the development of the LED lighting market. The decline in the price of LED lamps and government subsidies have promoted the growth of market demand. With the decline in the price of LED and the increase in the luminous efficiency of LED year by year, the recovery cycle of purchase cost has been significantly shortened. the willingness to drive the commercial and public sectors to replace lamps has been greatly improved, and the LED light source replacement tide has been officially launched. Among them, replacement light source products such as bulb lamps and lamps are popular in the market. LEDinside estimates that compared with 2013, the demand for LED bulb lamps will increase by 86 in 2014, while the demand for LED lamps will increase by 89. In addition to the manufacturer's price strategy, the bidding and subsidy policies of various regional markets are also of great help to improve the penetration rate of LED lighting. For example, there are still some regions in North America that continue to implement the EnergyStar subsidy project, and the subsidized lamp price is more acceptable to consumers.
