Luminaires placed on the market in the European Union must undergo a conformity assessment

Luminaires intended for use in potentially explosive atmospheres are assessed by certification bodies accredited under ATEX.

The certification body determines a test plan for the product based on the application, in accordance with which the product is tested and certified. The testing laboratory conducts tests in accordance with the test plan, after which, based on the test report, the certification body may declare the product compliant with the requirements and issue a certificate.

LED luminaires used for general lighting consist of three main components. The main components are the LED module, the driver and the luminaire housing.

The LED module usually consists of several LED arrays connected in series or in parallel. The choice of layout topology depends on several factors, such as the number and characteristics of the components, as well as the intended load of the luminaire.

A constant-current driver maintains the current supplied to the LED module at a constant desired level, whilst a constant-voltage driver regulates the voltage of the LED module. When using a constant-voltage driver, the current on the LED module must be limited. If an LED module is used without current limiting, the current drawn by the module will increase until the module fails due to excessive heating.

Luminaires and their testing are regulated by the Low Voltage Directive 2014/35/EU. The aim of the Low Voltage Directive is to ensure that electrical equipment within the European Union, when correctly installed, maintained and used for its intended purpose, does not pose a risk to human health and safety.

The compliance of LED luminaires is confirmed in accordance with the requirements of Directive 2014/30/EU on electromagnetic compatibility, the RoHS Directives, and photobiological safety.
