Abstract (en)
[origin: US4722039A] To control the light distribution of light emitted from a high-pressure discharge bulb (1) asymmetrically, to meet automotive head lamp legal and design requirements, a single unitary combination bulb holder and light distribution element (11) is secured to the base sleeve (4) for example by plastic rivets (8) securing a unitary bottom plate (9) to an alignment body (5, 6) which, in turn, is positioned in the base in predetermined relation to a base positioning ring (15) formed thereon. The light distribution body is trough-shaped, with the concave surface (14) facing the bulb, and extends parallel thereto.
