LED has become an effective solution for building lighting

In 2012, the National Development and Reform Commission, the Ministry of Finance and the Ministry of Science and Technology organized the 2012/2013 fiscal subsidy promotion project for semiconductor lighting products. In 2013, national Development and Reform Commission, Ministry of Science and Technology, Ministry of, the Ministry of Finance, the ministry of housing, quality inspection of the State Administration of the joint the the semiconductor lighting energy-saving industry planning of clear the promote LED lighting energy-saving industry growth target. It is estimated that the penetration rate of LED lighting in 2014 will be from 8 ~ this year. 10 climbed to 20 in one fell swoop, becoming another major force in digesting chip production capacity. Since the Ministry of Science and Technology LED the establishment of the National Semiconductor Lighting Project Coordination Group in 2003, the state has issued a series of policies to support the development of LED lighting industry. In 2009, the Ministry of Science and Technology launched the pilot project of ten cities wanzhan semiconductor lighting application project. On 2011, the National Development and Reform Commission, the Ministry of Commerce, the General Administration of Customs, the State Administration for Industry and Commerce and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the announcement on gradually prohibiting the import and sale of ordinary lighting incandescent lamps. general lighting incandescent lamps will be phased out by power from October 1, 2012. In 2012, the National Development and Reform Commission, the Ministry of Finance and the Ministry of Science and Technology organized and launched the 2012/2013 fiscal subsidy promotion project for semiconductor lighting products, leveraging the application of LED in the lighting field, especially for bulk users. The basic structure of the LED lamp is an electroluminescent semiconductor material, which is placed on a shelf with leads and then sealed with epoxy resin around to protect the internal core wire. therefore, LED has good seismic performance. LED is a rapidly developing technology and is widely used in many general lighting fields, commonly known as solid-state lighting. Typical applications of LED lighting are: indoor lighting (For commercial, industrial and residential environments)Outdoor lighting (Street lamp, parking lot lighting) As well as buildings, decorative lighting, etc. At the beginning, light emitting diodes were used for decorative lighting because they could emit color of the entire spectrum. In some cases, LED has become an effective scheme for building lighting. Compared with other lighting technologies, LED has better performance, thus becoming the mainstream scheme in the current general lighting market: 1. Compared with other lighting technologies, LED has a longer service life. The working life of LED is 50,000 hours, while that of incandescent lamp is only 1,000 to 2,000 hours. Small fluorescent lamp (CFL) The service life of is about 5,000 to 10,000 hours. The significant advantage in service life makes LED very suitable for commercial and industrial applications that require large labor costs to replace lighting lamps. 2. Energy efficiency is better than incandescent and halogen lamps, equivalent to fluorescent lamps. In addition, the efficiency of LED is also continuously improving. White LED (WLED) The efficiency is expected to increase by about 50 in the next 3 to 4 years. 3. Smaller dimensions. The overall dimensions of LED lamps are equivalent to MR16 and GU10, while CFL cannot meet such applications. 4. Appropriate drivers can be used to provide brightness level. For applications requiring brightness adjustment, fluorescent lamps have technical limitations. Although the traditional LED design has encountered similar problems, the innovative LED driver scheme provided by Maxim is compatible with SCR dimming and rear edge dimming design. 5. It has strong luminous directivity. Different from other lighting technologies, LED is very suitable for applications requiring directional lighting, such as small angle reflector lamps. 6. It has higher efficiency when the temperature is lower. The working efficiency of fluorescent lamps will decrease at low temperatures. In contrast, LED is very suitable for low temperature working environment, such as refrigerator lamp. 7/. The luminous color can be easily changed. This advantage makes RGBLED an ideal choice for building and scene lighting, and can change the light color in real time according to specific requirements.
