RoHS Testing for LED Products

Cost of EU ROHS certification for LED Luminaires?

RoHS is an environmental certification that tests for six hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). Its full name is the "Restriction of Hazardous Substances" Directive.

Overview of LED Technology

An LED lamp features an electroluminescent semiconductor material chip, which is cured onto a bracket using silver or white glue. The chip and the circuit board are then connected using silver or gold wire and sealed with epoxy resin around the perimeter to protect the internal core wire. Finally, the outer shell is installed. Because of this structure, LED lamps exhibit excellent shock resistance.

LED (Light Emitting Diode) is a solid-state semiconductor device capable of converting electrical energy into visible light; it can directly convert electricity into light. The heart of an LED is a semiconductor wafer. One end of the wafer is attached to a bracket (serving as the negative pole), while the other end connects to the positive pole of the power supply, meaning the entire wafer is encapsulated in epoxy resin.

Scope and Application of RoHS

RoHS targets all electrical and electronic products that may contain the six hazardous substances mentioned above within their production processes and raw materials. These primarily include:

• White goods: Refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc.

• Black goods: Audio and video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.

• Other Equipment: Power tools, electric and electronic toys, medical electrical equipment, etc.

Background of the Directive

On January 27, 2003, the European Union officially published the "Waste Electrical and Electronic Equipment Directive" (WEEE 2002/96/EC) and the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" (RoHS-2002/95/EC). The directive mandated that starting July 1, 2006, electrical and electronic equipment containing the six hazardous substances—lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE—are prohibited from being sold in the EU market. To date, the EU has issued 29 exemption regulations.

Specific RoHS Scope

• Applicability: Only applies to new products placed on the market from July 1, 2006, onwards. This includes household incandescent lamps and light sources. It must not violate specific directives or regulations regarding special safety and health requirements—such as the Vehicle ELV (End-of-Life Vehicles) Directive, and the Battery Directives (91/157/EEC, 93/86/EEC & 98/101/EC).

• Exclusions: * Medical devices or monitoring equipment (weee directive Categories 8 and 9).

• Repair spare parts placed on the market before July 1, 2006.

• Reused products originally placed on the market before July 1, 2006.

Process for ROHS Testing of LED Luminaires

• Step 1: The applicant fills out the application form and provides a bill of materials (BOM) for the product's components.

• Step 2: JJR engineers evaluate and determine the testing cost based on the material and color of the provided product.

• Step 3: After the applicant confirms the quotation, they sign the project application form and service agreement, pay the full project fee, and prepare the test samples (the specific number of test samples required will be communicated by the staff).

Step 4: Once the testing is passed, the report and project are finalized, and the official rohs test report is issued.
