Title:
可変焦点および方向性を有するランプアセンブリ
Document Type and Number:
Japanese Patent JP4709167
Kind Code:
B2
Abstract:
A lighting assembly comprises a housing (16) for attachment to a supporting member within the interior passage compartment of a motor vehicle, a light source (26) carried in the housing (16) for projecting light along a light path (28), and a power input (36) operatively connected to the light source (26) for selectively energizing the light source. An optical member (48), e.g. lens (50), is disposed in the light path (28) and is moveable between a flood position wherein light from the light source (26) is influenced by the optical member (48) to disperse the light over a generally wide area within the passenger compartment and a spot position wherein light from the light source (26) is influenced by the optical member (48) to focus over a generally narrow area within the passenger compartment. The optical member (48) is disposed within said housing (16) so as to be capable of orbital movement in the flood position and in the spot position regardless of whether the light source (26) is energized. A switch (74) is provided which is responsive to movement of the optical member (48) for automatically interrupting the operative connection between said power input (36) and the light source (26) when the optical member (48) is moved to the flood position and automatically restoring the operative connection when the optical member (48) is moved to the spot position so as to energize the light source (26) and thereby illuminate the passenger compartment with a focused beam of light.
