<p>The device incorporates a fixing collar (13) independent of the reflector (1) and capable of being mounted on the latter in two different positions in which, respectively, it provides a support for standardised means (12) on the base (6) of a bulb (4) of differing types. The collar (13) is fixed on the reflector (1) by snap engagement of catches (40, 41, 42) in anchoring holes (35, 36, 38, 39) on the reflector (1). A plug (45) locked on the collar (13) by a bayonet mounting (51, 52, 53, 54, 55) ensures the immobilisation of the bulb (4) with reference to the collar (13), and the whole assembly is dimensioned so that the plug cannot be locked on the collar (13) if the bulb (4) does not occupy a desired predetermined position with reference to it. <IMAGE></p> |
