IEC 62368-1 – Safety Standard for Electronics
IEC 62368-1 is an international safety standard for electronic equipment used in audio, video, communication and information technology. Instead of listing prescriptive design rules, it focuses on hazard-based safety engineering. This approach evaluates potential risks inside a device and ensures protective measures are in place to prevent injury, fire or electrical damage.
Manufacturers of LED systems, control units, power supplies and communication modules rely on IEC 62368-1 to ensure their products meet global safety expectations. Understanding this standard is essential for anyone involved in designing, installing or approving modern electronic equipment.
What IEC 62368-1 Covers
IEC 62368-1 applies to a wide range of electronic equipment including:
-
LED lighting drivers and control electronics
-
Power supplies and charging modules
-
Audio and video equipment
-
Communication and network devices
-
Industrial and vehicle-mounted electronics that use ICT components
Many lighting systems used in vehicles or marine environments incorporate ICT components such as processors, regulators and communication interfaces, which brings them under the scope of this standard.
The Hazard-Based Safety Approach
IEC 62368-1 uses a hazard-based model rather than prescriptive rules. Instead of dictating exact construction details, it identifies possible energy sources that could cause harm and requires manufacturers to add appropriate safeguards.
The three main steps are:
Identify the Energy Source
Examples include electrical energy, thermal energy, mechanical movement or radiation.
Classify the Energy Level
Energy sources are grouped based on their potential to cause injury or ignite materials.
Apply Suitable Safeguards
Safeguards can include insulation, thermal protection, enclosure design or circuit shutoff mechanisms.
This model offers more flexibility than older standards and supports modern, multifunction electronics.
How IEC 62368-1 Differs From Previous Standards
IEC 62368-1 replaces two legacy standards:
-
IEC 60065 (audio and video equipment)
-
IEC 60950-1 (information technology equipment)
Instead of treating AV and ICT equipment separately, IEC 62368-1 combines them under one hazard-based system. This is important for modern devices that integrate lighting, control electronics and communication features.

Key Requirements of IEC 62368-1
| Requirement | Purpose | Examples |
|---|---|---|
| Electrical safety | Prevent shock or overheating | Insulation, creepage and clearance |
| Fire protection | Stop ignition or flame spread | Flame-retardant materials, thermal cutoffs |
| Mechanical safety | Prevent injury from moving parts | Enclosures, guards, impact resistance |
| Thermal management | Avoid excessive heat buildup | Heat sinks, ventilation, temperature sensors |
| Component reliability | Ensure parts meet safety specs | Certified power supplies, tested connectors |
These requirements are especially relevant for LED drivers, control boards and power modules used in vehicle lighting systems and industrial applications.
Why IEC 62368-1 Matters
Manufacturers and integrators must comply with IEC 62368-1 when selling or installing products in regions that require it. Compliance ensures:
-
Safer operation over the equipment’s lifespan
-
Reduced risk of electrical faults or fire
-
Acceptance in international markets
-
Alignment with modern design practices
It also supports the growing trend toward smart lighting and connected equipment, where ICT and power electronics merge into a single system.
