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, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Housing and Urban-Rural Development, and the General Administration of Quality Supervision, Inspection and Quarantine jointly compiled the semiconductor. The Lighting Energy-Saving Industry Plan has clearly defined the goal of promoting the growth of LED lighting energy-saving industry. It is expected that the LED lighting penetration rate will climb from 20 to 10 this year to 20 in 2014, becoming another major force in digesting chip capacity.
Since the establishment of the National Semiconductor Lighting Engineering Coordination Leading Group in 2003 by the Ministry of Science and Technology, the state has issued a series of policies to support the development of the LED lighting industry. In 2009, the Ministry of Science and Technology launched a pilot project for the Ten City Wanhao Semiconductor Lighting Application Project. In 2011, the National Development and Reform Commission, the Ministry of Commerce, the General Administration of Customs, the General Administration of Industry and Commerce, and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the "Announcement on the gradual prohibition on the import and sale of ordinary lighting incandescent lamps". From October 1, 2012, the general lighting will be phased out according to the power. Incandescent lamp. In 2012, the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Science and Technology organized the 2012/2013 financial subsidy promotion project for semiconductor lighting products, inciting the application of LED in lighting, especially in the field of large-scale user lighting.
The basic structure of the LED lamp is an electroluminescent semiconductor material placed on a leaded shelf and then sealed with epoxy resin to protect the internal core wire, so the LED has good seismic performance. LEDs are a rapidly evolving technology that is being widely used in many general lighting applications, often referred to as solid state lighting. Typical applications for LED lighting are: indoor lighting (for commercial, industrial and residential environments), outdoor lighting (street lights, parking lot lighting), and architectural, decorative lighting, etc. Initially, LEDs were used because they were capable of emitting color throughout the spectrum. For decorative lighting.
In some cases, LEDs have become an effective solution for architectural lighting. Compared with other lighting technologies, LEDs have superior performance and thus become the mainstream solution for the current general lighting market:
1. LEDs have a longer life than other lighting technologies. LEDs have a working life of up to 50,000 hours, while incandescent lamps have a lifespan of only 1,000 to 2,000 hours, and compact fluorescent lamps (CFLs) have a lifetime of about 5,000 to 10,000 hours. The significant advantages in service life make LEDs ideal for commercial and industrial applications that require significant labor costs to replace lighting.
2. Energy efficiency is better than incandescent and halogen lamps, equivalent to fluorescent lamps. In addition, the efficiency of LEDs is also increasing; the efficiency of white LEDs (WLEDs) is expected to increase by about 50 in the next three to four years.
3. Smaller form factor. LEDs are the same size as MR16 and GU10, and CFLs are not suitable for this type of application.
4. Brightness adjustment can be provided with a suitable driver. Fluorescent lamps are technically limited for applications that require brightness adjustment. Despite the similar problems with traditional LED designs, Maxim's innovative LED driver solutions are compatible with TRIAC dimming and trailing edge dimming.
5. Has a strong directionality of illumination. Unlike other lighting technologies, LEDs are ideal for applications that require directional lighting, such as small angle reflectors.
6. Higher efficiency at lower temperatures. The operating efficiency of fluorescent lamps decreases at low temperatures. In contrast, LEDs are ideal for low temperature work environments such as refrigerator lights.
7. Easily change the color of the glow. This advantage makes RGBLED an ideal choice for architectural and scene lighting, allowing you to change the color of the light in real time based on specific requirements.
