LED poisonous and harmful substance detection

Basic introduction

In the 21st century today, as the greenest energy-saving light source, LED has been replacing traditional light sources and has become the protagonist of lighting appliances. In addition to energy saving considerations, environmental protection requirements are also one of the priorities of this century. Do LED lights use environmentally friendly materials? Is the material harmful to people and the environment? This is another major issue we face.

Restriction of harmful substances

a. EU RoHS Directive
EU: Directive 2011/65 / EU of the European Parliament and of the Council of 8 June 2011 on the Restriction of the use of Certain Hazardous Substances in Electrical and Electronic equipment, i.e. EURoHS directive

The above regulations control the content of the following six restricted substances in various homogeneous materials in LED lamps:
Lead: 1000ppm, Cadmium: 100ppm, Mercury: 1000ppm, Hexavalent chromium: 1000ppm, Polybrominated biphenyls: 1000ppm, Polybrominated diphenyl ethers: 1000ppm
