TÜV Rheinland Test Report: Self-ballasted LED Lamps

General Product Information

Product Function and Intended Use: The EUT (equipment under test) is an ordinary self-ballasted LED lamp for lighting and similar use.

Ratings and System Details:

• Rated input: AC 120 V, 60 Hz, 37 mA
• Rated power: 3.3 W
• RF IC: SiMG301

Independent Operation Modes: The basic operation modes are "ON" and "OFF". The test modes were:

• Mode 1: Warm lighting with the maximum lighting output.
• Mode 2: Warm lighting with the minimum lighting output.
• Mode 3: White lighting with the maximum lighting output.
• Mode 4: White lighting with the minimum lighting output.

Highest Frequency: The highest frequency used in the EUT is 2480 MHz.

Test Setup and Operation Modes

Test Procedure Overview:

• Conducted emission tests were performed on 2025-03-20.
• Radiated emission tests were performed on 2025-03-24 to 2025-03-28.

Test Setup Diagrams:

Conducted Emission Setup: The setup includes the EUT, LISN, Transformer, Power Supply, EMI receiver, and Computer.

Radiated Emission Setup (30 MHz – 1000 MHz): The setup involves the EUT placed on a turntable, a receiving antenna at a 3-meter distance, and absorbers. The antenna polarization was varied (horizontal and vertical).

Radiated Emission Setup (1 GHz – 18 GHz): Similar to the 30-1000 MHz setup, with the antenna at a 3-meter distance.

Test Software: The "Home" APP for iPhone was used.

Auxiliary Equipment:

• Mobile phone: iPhone 15 (Apple)
• Loudspeaker: HomePod mini (Apple)
• Remote control: E2489 (IKEA)
