General Product Information

The Equipment Under Test (EUT) is an ordinary LED lamp for lighting and similar use.

Operation Modes:

• Mode 1: EUT powered by power supply, lighting on with dimming.
• Mode 2: EUT powered by laptop, lighting on with dimming.

Submitted Documents: Circuit diagram, user's manual, and rating label.

Test Set-up and Operation Modes

Principle of Configuration Selection: The EUT was configured to measure its highest possible emission level. Test conditions were adapted according to the instructions for use.

Sequence of Testing: Conducted emission tests were performed on 2025-05-22. Radiated emission tests were performed on 2025-05-29.

Equipment and Cable Arrangement:

Conducted Emission Setup: A block diagram shows the EUT connected to a Line Impedance Stabilization Network (LISN), which is connected to an EMI receiver and a computer. A transformer and power supply are also part of the setup.

Radiated Emission Setup: A block diagram illustrates the EUT placed on a support, with an antenna positioned at a distance (1-4m) and connected to an EMI receiver.

Test Software: No special test software was used.

Special Accessories and Auxiliary Equipment: Adaptor (model: ICPSW5-5NA-1, brand: IKEA) and Laptop (model: T45, brand: IKEA) were used as power supply.

Countermeasures to achieve EMC Compliance: No special measures were employed.

Conformity Decision Rule

For all EMI tests, compliance is determined by directly comparing measurement results with corresponding limits, as measurement uncertainties are less than the values specified in CISPR 16-4-2.
