With the continuous updating of LED lighting products, their industry standards and technical standards are changing with each passing day. The latest version of "Lamps Part 1: General Requirements and Tests" GB7000.1-2015 was implemented on January 01, 2017. At the same time, standards such as IEC/EN60598-1 have changed. How to comply with the changes of standards and manufacture products that meet the requirements of local technical standards, regulations and certification systems is a key part of export enterprises successfully breaking through the international market and breaking testing and certification and technical trade barriers. Recently, the Aladdin News Center reporter interviewed Huang Baobin, the general manager of Shenzhen Nanfang Lixun Testing Co., Ltd., to interpret the latest changes in lighting testing standards, and to see the changing trend of the lighting market from the perspective of technical standards, regulations and certification systems. Qiu Zhiwei (right), Chairman of Shenzhen Lixun Testing Co., Ltd. and Huang Baobin (left), General Manager of Shenzhen Nanfang Lixun Testing Co., Ltd. New and old standards: mainly for the requirements of changes in marking and structure for the blue light hazard of LED light sources and lamps, Huang Baobin gave us a detailed introduction to the recent changes in LED lighting product standards. According to reports, the changes in the new luminaire standard GB7000.1 (IEC/EN 60598-1) are mainly reflected in the changes in marking and structure. Huang Baobin said that the changes and applications of standards are all found after the products are used in a large amount, and the standards are revised to make the products safer in people's daily use. There are two main impacts of the new standard on the lighting industry. One is the change of the mark, the indicator for the warning or the prompt is more visual and easy to understand; the other is the evaluation of the blue light of the LED, which is a controversial blue light hazard. It has become a restrictive issue for the promotion and application of LED lighting products, which has affected the consumer confidence of the market. In the eighth edition of the revision process, IEC 60598-1 Luminaires-Part 1: General requirements and tests focused 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. Among them, the specific changes are as follows: 1. Mark A, the mark on the lamp (1) For lamps with different IP numbers for different parts, the IP20 should also be marked; the use of the cover will increase the IP rating when it should be in the cover New IP numbers are provided; (2) Marking regulations are not required for the luminaires to be mounted on the surface of flammable materials; for markings that are not suitable for installation on flammable materials, the marking regulations are modified; for those not suitable for covering with insulating materials , modified the markup rules; see the new and old version of the installation surface symbol difference comparison table 1. (3) Added marking requirements for photobiohazards for luminaire products classified as threshold illuminance Ethr; see photobiosafety symbol comparison table 2. (4) Added the symbol of the fixed cover that covers the non-user replacement light source for protection against electric shock, the height is not less than 15mm; Warning, electric shock hazard ---- B, additional content 1 adds non-replaceable light source and non-user replacement Light source luminaire instructions; For non-replaceable light sources: The light source of this luminaire is not replaceable; when the light source reaches its end, the entire luminaire should be replaced for non-user replacement of the light source: The light source within this luminaire should be manufactured by the manufacturer or its service Agents or similarly qualified persons to replace the warning, electric shock hazard 2 increase For the controllable luminaire, the insulation category requirements maintained between the LV power supply and the control conductor should be given; 2. Structure 1 on the protective screen, in the applicable product Metal halide lamp fixtures have been added; appropriate warnings are provided for lamps that require a shield for the structure of the fixture, or their packaging is marked with this symbol;---- for lamps that do not require a shield as a component of the fixture (self-contained shield) Lamp), its packaging is marked with the following symbols; --- 2 increases the assessment requirements for retinal blue light hazard; evaluation according to IEC/TR 62778, The blue light hazard level of the light source is RG0, RG1, Ethr; the light source with the blue light hazard group greater than RG2 should not be used; the night light installed by children with removable lamps and power sockets should not exceed RG1; For luminaires with non-replaceable light sources and non-user replacement light sources, luminaires with non-replaceable light sources are required: it is not possible to replace and touch live parts unless the luminaire or its components are damaged; 1) Designed and shaped to be used only once Sealed, or glued, or screw-mounted luminaire parts, or permanently embedded baffles, should not be opened; 2) luminaire parts that can be opened by hand or using tools to access the light source should be opened or removed, after the parts are removed It meets the requirements for protection against electric shock and should not touch live parts. It has a non-user replacement light source: there is a fixed cover that provides protection against electric shock, and the cover has at least two independent fixing members to reliably hold it, and the cover has Warning, electric shock hazard symbol; 4 increased insulation between circuits. The transformer or control unit contained in the luminaire is insulated from the LV power supply.
This shear is mainly used for cutting all kinds of scrap metal, which belongs to one of the scrap metal recycling equipment. Our shears mainly include hydraulic metal gantry shears, horizontal box shears, crocodile shears, gantry shears, etc. This type of shear is driven by hydraulic pressure, and it can also be used with a diesel generator in places where there is no power supply. These scrap metal shears are suitable for all kinds of large and small scrap metal recycling plants.
