The main components are the base (2), the light distribution diffusor or reflector (3, 4), pref. four holders (21) for mounting in an aperture (6) in a body (7), an edge portion (8), and power supply equipment (9) for lamps (11) in eg. two lampholders (10). The base and the light distributor are fitted to the holders (21) so that they can be detached and can execute only limited movement between operative and inoperative positions, their connection being offset from the centre of the assembly. |
