무엇 are T그는 Main Quality C온트롤 SLED 표준 Neon Strips?

전기 안전 표준

EN 60598 Series: EN IEC 60598 is a European regional standard on lighting equipment, which applies to all kinds of lighting apparatus, including but not limited to indoor lighting, outdoor lighting, LED lamps, and lanterns. This standard is derived from the International Electrotechnical Commission (IEC) 60598 series of standards, which is widely applicable worldwide. The EN IEC 60598 standard is mainly used to assess the performance of lighting equipment in terms of electrical safety, mechanical safety, thermal effects, and other aspects that may be involved in the process of installation and use to ensure that the product meets the basic requirements of safety, health, and environmental protection. Among them, EN 60598-2-14 is specifically for neon lamps and lanterns, including structural design, insulation performance, and voltage withstand tests.

IEC/EN 61347-2-11: Standardizes the safety requirements for neon strip power supply equipment. The International Electrotechnical Commission (IEC) has issued the latest version of the safety standard for light source controllers: IEC 61347-2-11:2024 “Safety of control gear for electric light sources—Part 2-11: Particular requirements for miscellaneous electronic circuits for use with luminaires.”

UL Standards: UL 8750 (Safety of LED Devices) and UL 2108 (Low Voltage Lighting Systems) for the North American market. UL 8750 and UL 2108, as two important UL safety standards, regulate the safety of LED devices and low-voltage lighting systems respectively, and the recent revisions of UL 8750 have involved the refinement of the compatibility of LED controllers and arrays (e.g., supplementing the definition of special-purpose LED arrays), and the refinement of the compatibility of LED controllers and arrays. Recent revisions to UL 8750 have included compatibility refinements for LED controllers and arrays (e.g., adding definitions for special-purpose LED arrays), while UL 2108’s test program focuses more on system-level stability verification.

Electromagnetic Compatibility (EMC)

EMC refers to the electronic products in the electromagnetic field interference size (EMI) and anti-interference ability (EMS) of the comprehensive evaluation, is one of the most important indicators of product quality, electromagnetic compatibility by the test site and test equipment.                     

EMI testing includes the following items:

• Conducted Emission (CE): Measurement of electromagnetic interference generated through conduction paths such as power lines.
• Radiated Emission (RE): Measurement of the intensity of electromagnetic radiation emitted by equipment in different frequency bands to ensure compliance with specified limits.
• Harmonic: Assesses the harmonic impact of the device on the power grid.
• Flicker: Evaluates the flicker impact of the device on the grid.

The EMS test includes the following items:

• Electrostatic Discharge (ESD): Evaluates the equipment’s immunity to electrostatic discharge.
• EFT: Simulates the effects of high-frequency electromagnetic pulses on equipment.
• Voltage Drop (DIP): Evaluates the immunity of a device to voltage drops.
• Conducted Surge (CS): Evaluates the ability of a device to withstand conducted interference.
• Surge: Evaluates the immunity of a device to surge voltages.
• PSMS: Evaluates the immunity of a device to industrial frequency magnetic fields.

Energy Efficiency and E환경 S표준

ErP Directive (2009/125/EC): Requires LED products to comply with energy efficiency labeling and eco-design requirements, such as ERP certification. The chart below shows the latest European energy efficiency class corresponding to the light efficiency:

RoHS and REACH: Restriction of the use of hazardous substances (e.g., lead, mercury) and chemicals to ensure that materials comply with environmental requirements. RoHS (Restriction of Hazardous Substances Directive) belongs to the European Union Directive (Directive 2011/65/EU), which needs to be transposed into the national laws of member states to take effect. REACH is an EU regulation (Regulation (EC) No 1907/2006) and is directly applicable in all member states without the need for transposition.

Photobiological Safety

EN 62471: Evaluates the risk of light radiation (e.g., UV, blue light hazards) from LED light sources to prevent harm to humans. By quantifying the radiation intensity, wavelength distribution, and exposure duration of the light source, it classifies the risk level (exemption level, low, medium, and high risk), provides a safety basis for product design and use, and reduces the risk of chronic eye disease or skin damage caused by light radiation.
