1 Light Sources Input IEC delegation to GRE to OVIG, 19,20 June 2007 GRE-OVIG-Working Paper No. 2007-03 (1 st session of the GRE Informal Group on Operating Voltage, 19-20 June 2007)

2 Design of Light Sources Bound to: Laws of physics Defined operating conditions Specified performance requirements Unavoidable compromises

3 Voltage conditions R37 Test voltage Head Lighting: 13,2V* Test voltage Signalling: 13,5V* DC *other regions mostly lower R99 Test voltage 13,5V Electronic light source control gear (ballast)

4 Control gear (ballast) R48 2. 7. 1. 2. "Electronic light source control gear" means one or more components between supply and light source to control voltage and/ or electrical current of the light source; R99 3. 1. 2. " Ballast ": Specific electrical supply for the gas-discharge light source.
