The so-called: state-owned national law, the family has family rules. Of course, in our LED industry, there is also no rule. Today, Xiaobian brings you some news about the release or progress of various new LED regulations at home and abroad. Xiao Bian believes that as a person in the industry, if you understand this, readers will definitely not read it after reading it.

Foreign UL update directly replaces fluorescent tube LED lamp technology resolution US Underwriters Laboratories (UL) updated the LED lamp technology resolution for direct replacement of fluorescent tubes on August 25, 2016. This latest technical resolution replaces The old version was issued on February 20, 2015 and is scheduled to be officially incorporated into the ul1993 (self-ballasted lights and their adapters) standard by the end of this year. According to reports, this latest technical resolution broke through the technical bottleneck of the previous typealed lamps entering the North American market in several aspects, and it is expected that ul can help more LED manufacturers to quickly enter typealed lamps into the North American market and directly replace the number of North American markets. Numerous double-ended straight (t12, t10, t8, t5, etc.) lamps, u-shaped tubes, single-ended cfl tubes and ring tubes. According to the inspection and quarantine personnel, the contents of this latest technical resolution are updated as follows: First, the test uses constant current power supply mode to replace the original constant voltage power supply mode, canceling the original current limit; second, if the Type A LED tube Replacing only the T5 fluorescent tube used in the electronic ballast, the DC component between the LED tube and the pin of the lamp cap is not required; the third is if the LED tube is made of metal or with other contactable non-current-carrying metal The clearance requirements of the parts, the pin needle to the metal parts are lower than before; the fourth is that the parts failure test is changed from the reading after 5 seconds to the reading after 5 minutes; the fifth is the test method for determining the cathode impedance. The above changes can be seen. On the one hand, the new resolution has improved the detection method of some parts of the LED tube. On the other hand, the new resolution has made more detailed, scientific and more stringent technical requirements for the LED tube. The inspection and quarantine department recommended that the new technical resolutions should be interpreted word by word, grasp the basic content of the new regulations, thoroughly understand the norms of the new regulations, and sort out the similarities and differences between the old and new regulations. All enterprises should combine their own LED product characteristics, select representative samples, start from the similarities and differences between new and old technology standards, combine specific products, theory and practice, improve and improve the quality of their products, and make enterprises in a dominant position in the international trade environment. DOE Releases the Latest General Lighting Application Solid-State Lighting Energy-Efficient Biennial Forecast Recently, the US Department of Energy (DOE) released the latest version of the general-purpose lighting application for solid-state lighting energy-saving biennial forecast. The report focuses on the US general lighting market, and the new report uses the latest 2015 US lighting market model and pushes the extension of the previous edition's forecast period of 2030 to 2035. According to the US Department of Energy, the amount of smart LED bulbs in 2015 is negligible. In 2035, LED smart bulbs will account for 15% of all A-type bulbs in the US, and will increase to 600 million. Type A bulbs usually refer to light source products with a pear-shaped, medium-sized spiral head and a spherical illumination angle. Incandescent lamps, halogen lamps, compact fluorescent lamps and LED bulbs are all categories of A-type bulbs. According to the US Energy Independence and Security Act (EISA2007), which came into effect in 2007, the US government has set energy efficiency limits for high-power products, so incandescent lamps are gradually withdrawing from the US market, and consumers can only choose halogen lamps and compact fluorescent lamps. Or LED bulbs. In 2015, the amount of all A-type bulbs in the United States was 3.2 billion, including about 200 million incandescent lamps, about 1 billion halogen lamps, about 1.7 billion compact fluorescent lamps, and about 300 million LED bulbs. It is expected that by 2023, the amount of LED bulbs will exceed that of compact fluorescent lamps. By 2035, the amount of LED bulbs will increase to 3.6 billion, accounting for about 90% of the total use of 4 billion A-type bulbs. The amount of fluorescent lamps will be reduced to 300 million, the amount of halogen lamps will be reduced to 100 million, and incandescent lamps will completely withdraw from the US market. DOE Announces Integrated LED Lamp Test Requirements The US Department of Energy (DOE) issued a federal bulletin on the test procedure for integrated LED lamps on July 1, 2016. Integral LED lamps required to enter the United States must be tested in a qualified laboratory in accordance with the requirements of this test procedure to obtain total luminous flux, input power, efficacy, correlated color temperature, color rendering index, power factor, lifetime and standby. Data such as power. The regulation came into effect on August 1, 2016 and will be enforced on December 28, 2016. According to the requirements of this regulation, the above parameters must be tested in accordance with the standards of LM-79, LM-84, TM-28 and IEC6 2301. In addition, from August 1, 2016, DOE-controlled LED Lighting Facts (color label) will be suspended for all new replacement Lamps submissions, as the new integrated LEDLamps DOE test program: DEPARTMENT OF ENERGY 10 CFR Parts 429 and 430 will take effect on August 1, 2016. Moreover, DOE is about to officially release the non-integrated LEDLamps test program for non-integrated LEDLamps. Any application for listing submitted before August 1, 2016 will continue to be processed. Products that have already been listed for the DOE LED Lighting Facts are still kept in the database database. The LED Lighting Facts Working Group will conduct further investigations and research on the latest DOE regulations and will notify all partners as soon as a final decision is made. DOE LED Lighting Facts will continue to accept the delivery of LED luminaires and refurbished kits. DLC has also revised its requirements for LED Lighting Facts. From August 1, 2016, it is no longer required to submit LM-79 data for bare lamps to LED Lighting Facts. DLC will continue to accept certification applications for lamps. This change does not affect DLC's requirements for LEDLightingFacts for other categories of products. LED blue light hazard assessment latest standard IEC/TR 62778:2014 LED blue light hazard has been controversial, and once became a limiting issue in the promotion and application of LED lighting products, affecting the market consumer confidence. IEC 60598-1Luminaires-Part 1: General requirements and tests In the eighth edition of the revision process, the focus is on the identification requirements for blue light hazards of LED lamps. This standard is a basic requirement for luminaires and is cited by most countries and regions around the world. At present, the basic standard for photobiohazard of lighting products in the IEC standard system is IEC 62471 series standard. Since LED lighting products involve product chains such as LED chips, LED packages, LED modules and LED lamps, if LED lighting is used in various product stages. The retinal blue light hazard evaluation of the product will bring a lot of repetitive work. To this end, the IEC Technical Committee IEC/TC34 published the technical report IEC/TR 62778:2014, which aims to apply the IEC 62471 to the blue light hazard of LED light sources and lamps. Evaluation. Domestic LED bulbs can be listed and sold after the implementation of the energy efficiency label. According to the National Development and Reform Commission's “Non-directional self-ballasted LED lamp energy efficiency labeling implementation rules for general lightingâ€, as of October 1, 2016 Non-directional self-ballasted LED lights for ordinary lighting (commonly known as LED bulbs) will have to be labeled with energy efficiency to be available for sale.
