Light source module definition

Light source module means an optical part of a device which is specific to that device, is containing one or more non-replaceable light sources, and is only removable from its device with the use of tool(s). A light source module is so designed that regardless the use of tool(s), it is not mechanically interchangeable with any replaceable approved light source;

Light source module means an optical part of a device which is specific to that device, It contains one or more non-replaceable light sources and it may optionally contain one or more holders for approved replaceable light sources. 2.7.1.1.4. "Filament light source" (filament lamp) means a light source where the element for visible radiation is one or more heated filaments producing thermal radiation. 2.7.1.1.5. "Gas-discharge light source" means a light source where the element for visible radiation is a discharge arc producing electro-luminescence / fluorescence. 2.7.1.1.6. "Light-emitting diode (LED) light source" means a light source where the element for visible radiation is one or more solid state junctions producing injection- luminescence/fluorescence. 2.7.1.1.7. "LED module" means a light source module containing as light sources only LEDs. However, it may optionally contain one or more holders for approved replaceable light sources. 2.7.1.2. "Electronic light source control gear" means one or more components between supply and light source, whether or not integrated with the light source or the applied lamp, to control voltage and/ or electrical current of the light source. 2.7.1.2.1. "Ballast" means an electronic light source control gear between supply and light source, whether or not integrated with the light source or applied lamp, to stabilize the electrical current of a gas-discharge light source. 2.7.1.2.2. "Ignitor" means an electronic light source control gear to start the arc of a gas-discharge light source. 2.7.1.3. "Variable intensity control" means the device which automatically controls rear light signaling devices producing variable luminous intensities to assure the unvarying perception of their signals. The variable intensity control is part of the lamp, or part of the vehicle, or split between the said lamp and the vehicle. 2.7.2. "Equivalent lamps” means lamps having the same function. These may have different characteristics from those installed on the vehicle when it is approved on condition that they satisfy the requirements of this Standard. 2.7.3. "Independent lamps" means devices having separate apparent surfaces in the direction of the reference axis, separate light sources and separate lamp bodies. 2.7.4. "Grouped lamps" means devices having separate apparent surfaces in the direction of the reference axis and separate light sources, but acommon lamp body.
