[In-depth analysis] LED lighting industry development in the first half of the year
In the second quarter of 2015, the country continued to promote various reforms, canceled the subsidies to EMC, and welcomed the development opportunities of PPP with wider capital participation, which is expected to bring LED applications to the next level; as the market matures and technology Progress, the product shifts from price to price, whether it is domestic market or international market, the price of LED products has shown signs of recovery; the rise and fall of production and sales reflects the general trend of LED lighting penetration, and enterprises are up and down in the big waves, sure M&A integration and investment expansion will be the focus of 2015. A. Policy PPP development welcomes opportunities. The international standard for product testing is the first to cancel the EMC subsidy. The PPP prospects can be issued by the State Council on the “Decision on Cancellation of Non-Administrative License Approval Itemsâ€, and then cancel 49 non-administrative license approval items, and 84 items will be cancelled. The administrative licensing approval items are adjusted to internal government approvals. Among them, the cancellation of non-administrative licensing approval items includes the approval of the financial incentive fund for contract energy management projects jointly approved by the National Development and Reform Commission and the Ministry of Finance in accordance with the Interim Measures for the Administration of Financial Reward Funds for Contract Energy Management Projects (Cai Jian (2010) No. 249). . As a variant of contract energy management (EMC), PPP public-private partnerships are a business model for public infrastructure projects. Representatives of public partners are local and national governments, and private partners can be private companies, state-owned companies or corporate consortia in specific areas of expertise. Under normal circumstances, the amount of EMC does not exceed 10 million yuan, and the amount of PPP can reach 100 million yuan. Since the PPP model emphasizes the deep participation of social capital, promoting this model is conducive to revitalizing social stock capital, stimulating the vitality of private investment, raising funds for urbanization, controlling government debt, easing financial pressure, and helping the government better. Transform functions and promote reform of the fiscal and taxation system. International standards and standards CIE publishes international standards for LED product testing. Recently, the International Commission on Illumination (CIE) released the international standard CIES025: 2015 "Test methods for LED lamps, lamps and modules", which is the world's first international standard for LED product testing methods, which will also be used as a European standard ( EN) Release implementation. According to the CIE process, the standard will soon be converted to a formal ISO standard by the International Organization for Standardization (ISO). In addition, the International Electrotechnical Commission (IEC) will directly refer to relevant content. Accurate and reliable measurement of light color parameters of LED products is a basic requirement for evaluating product performance and designing lighting systems, that is, the consistency of data measured in different laboratories must be ensured to achieve comparison of different products under the same benchmark. Based on this concept, CIES025 presents reproducible luminosity, colorimetric test requirements, and recommendations for test data reporting for LED lamps, fixtures, and modules. Measurement parameters include total luminous flux, luminous efficacy, partial luminous flux, light intensity distribution, central intensity, brightness, brightness distribution, color coordinates, correlated color temperature, color rendering index, and character uniformity. Also, the EU updated the lighting safety standards. Recently, the corresponding European version of EN62776:2015 was issued, which provides a theoretical basis for the safety assessment of LED tube manufacturers exporting to Europe. The standard is referred to as "IEC/EN62776Double-capped LED lamps designed to retrofit linear fluorescent lamps Safety specifications". The main updates include updates to standards: based on the structural characteristics of different products, updated some of the IEC/EN60598-2 standards; with LED luminaires as the focus of attention, increased the optical, electrical and structural safety requirements for LED luminaires; Also updated some of the test requirements for Class III products. In May 2014, the general safety requirements for luminaires IEC60598-1:2014 (8th edition) were officially published, which replaced the previous version of IEC60598-1:2008 (7th edition); in January 2015, the corresponding EN standard EN60598-1:2015 is also in force and will officially replace the previous version of EN60598-1:2008+A11:2009 on October 20, 2017. 123456
