New but with a bright future ahead
LED-based lighting solutions have been described as the light source of the future, tiny and more energy-efficient than any other light source, easy to control and with a long service life, and they can be used for almost any lighting application.
They are set to revolutionize lighting and provide a welcome boost to the industry, accounting for around 60% its revenues worldwide by 2020.
The use of LED (light-emitting diodes) modules for general lighting applications is relatively recent. Acknowledging the need for relevant tests for this new source of electrical light, sometimes called “solid state lighting”, IEC SC 34A prepared IEC 62031, LED modules for general lighting – Safety specifications.
IEC 62031 was published in January 2008. Following publication of a first amendment in October 2012, a consolidated version of this International Standard is now available.
Provisions in the standard "represent the technical knowledge of experts from the fields of the semiconductor industry and those of the traditional electrical light sources". IEC 62031 covers LED modules with integral and external control gear. LED modules require electronic control gear designed to provide constant voltage or current. In LED lamps equipped with a lamp cap (self-ballasted lamp) intended to replace existing lights, such as incandescent bulbs, the control gear is integrated into the lamp.
The consolidated standard is very comprehensive and covers the following details:
- Terms and definitions
- General requirements
- General test requirements
- Terminals (screw, screwless & connectors)
- Provisions for protective earthing
- Protection against accidental contact with live parts
- Moisture resistance and insulation
- Electric strength
- Fault conditions
- Conformity testing during manufacture
- Resistance to heat, fire and tracking
- Resistance to corrosion
Four annexes to the Standard cover: tests; an overview of systems composed of LED modules and control gear; conformity testing during manufacture and information for luminaire design.
Given the spectacular growth of the LED lighting sector, this consolidated version of an International Standard which will help ensure LED modules are safe will be essential for all producers of all such modules.
