The new national standard GB7000.1-2015 will be enforced on January 1 next year.
Recently, the China Quality Certification Center issued the "Notice on the Implementation of the New Version of GB 7000.1-2015 for Compulsory Certification of Lamps and Products". The notice pointed out that GB7000.1-2015 "Lighting Part 1: General Requirements and Tests" (hereinafter referred to as the new version of the standard) will be implemented on January 1, 2017. The implementation of the recent day, China Quality Certification Center issued "on the compulsory lighting products Notification of the implementation of the new version of the standard GB 7000.1-2015 requirements. The notice states that GB7000.1-2015 "Lighting Part 1: General Requirements and Tests" (hereinafter referred to as the new version of the standard) will be implemented on January 1, 2017, and will replace GB7000.1-2007 "Lighting Part 1" from the date of implementation. : General Requirements and Tests (hereinafter referred to as the old standard). There are many differences between the new and old standards, among which the following four points are the most typical 01, the nameplate mark has undergone major changes. The F series marks that are very familiar to the enterprise are no longer used in GB7000.1-2015, and are changed to visualized pattern warning marks, as follows The figure shows. 02. Defining blue light hazard requirements 1. Luminaires with integral LED or LED modules should be evaluated for blue light hazard according to IEC/TR 62778. 2. For children's portable lamps and nightlights, the blue light hazard level measured at a distance of 200mm shall not exceed RG1. 3. For portable lamps and portable lamps, if the blue light hazard level measured at a distance of 200mm exceeds RG1, you need to mark the symbol on the outside of the lamp without looking at the light source, as shown in the figure below. At the same time, the position of the symbol should also be able to prevent the user from seeing the light source while seeing the symbol. According to the above requirements, the company should not mark the symbol on the mounting surface or the illuminating surface such as the LED desk lamp. 4. For fixed luminaires, if the blue light hazard level measured at a distance of 200mm exceeds RG1, it is necessary to test to determine the critical distance of the luminaire just at RG1. The manufacturer should give this distance value in the product specification to provide a reference for lighting designers and builders. 03. Reducing the SELV circuit diameter requirements The standard 5.2.2 stipulates that if there are sufficient mechanical properties and current carrying capacity, the external cable in the Class III luminaire or the SELV circuit in the luminaire, or other types of luminaires for the parts For a Class III connection, the cross-sectional area of ​​the conductor in a circuit with a maximum rated current not exceeding 2A may be less than 0.75 or 1.0 mm2, but not less than 0.4 mm2. 04. It is not allowed to ground through the built-in control device. A new regulation is added in Article 7.2.1: It is not allowed to ground the lamp through the built-in control device. However, some luminaires currently on the market often use the grounding wire of the built-in control device as the grounding wire of the luminaire. According to the requirements of the new standard, a qualified method is to connect the grounding wire of the luminaire to the metal casing of the luminaire, and then connect the grounding wire of the built-in control device to the grounding wire of the luminaire, as shown in the following figure.
