LED lamps new national standard blue Hazard Class

Lamps latest national standard GB7000.1-2015 "lighting - Part 1: General requirements and tests" was released December 31, 2015, and will take effect January 1, 2017 implementation. The standard compared to the current standard GB7000.1-2007 exists a big difference, lighting manufacturers will have a substantial impact. This paper introduces a new standard of some of the more typical differences in terms of reference.

1, nameplate marking significant changes

Companies are very familiar with the F-Series mark GB7000.1-2015 no longer used, to visualize the pattern of warning signs, as shown below.

2, clear blue light hazard requirements

Lamps with integral LED or LED module blue light hazard assessment should be carried out according to IEC / TR 62778.

For children with luminaries and night light, measured at a distance at 200mm blue hazard rating shall not exceed RG1.

For luminaries and portable lights, if the hazard rating at 200mm distance measured over blue RG1, you need to mark "do not stare at the light source and see" external lighting symbol prominently, as shown below. At the same time, mark the location of the symbol should be able to prevent users from seeing the symbol also saw light. According to the above requirements, companies should not be the symbol marked on the mounting surface such as a surface or light LED lamp.

For fixed luminaires, if the hazard rating than RG1 distance measured at 200mm blue, we need to test to determine the lighting just in time critical distance RG1. The manufacturer shall give the distance value in the product specification, to provide reference for lighting designers and construction side.

3, reducing the requirements for SELV circuit Wire

Standard 5.2.2 provides that if there is a sufficient degree of mechanical characteristics and current carrying capacity, Class III luminaires or fixtures of external cables of SELV circuits, or other types of lamps for Class III connection between the components, the maximum rated current does not exceed 2A circuit wire cross-sectional area may be less than 0.75 or 1.0 mm2, but not less than 0.4 mm2.

4, It’s not allowed by the built-in control device grounding

Standard 7.2.1 added a provision: lighting control device via built-in grounding is not allowed. However, some of the lamps on the market will tend to built-in controller that comes with the ground line as light ground. Under the new standards A qualified approach is first and lighting fixture ground wire attached to the housing, the grounding wire and grounding wire built-in lamps and then the control unit connected.
