Integral housing and lens retention spring for a lighting fixture

#This invention relates to track lighting systems and more particularly to an integral housing and lens retention spring.

#Track lighting systems allow installation of light fixtures using a single set of track conductors. Track lighting systems can provide light over a wide area and can be used to accentuate specific objects within a room. Thus, track lighting systems are widely used both in private residences as well as in publicly accessible buildings, such as commercial establishments and museums.

#Track lighting systems come in a variety of shapes, sizes, and configurations. More commonly, the track frame is configured as an elongated rectangle or strip. Track lighting systems typically include spot light fixtures that are inserted along the narrow, electrified track frame. One side of the track frame mounts to a ceiling or wall and the side opposite the mounting surface usually has an opening along the length of the track frame for inserting light fixtures. The component of the light fixture that inserts into the track usually provides both an electrical connection with the track conductors and a mechanical connection to secure the fixture.

#Referring to FIG. 1, a track light system 100 includes a track network 101, a connector 102, interfaces 103, a lamp holder 104 with a constant tension lamp arm with integral rotation stop, a lamp holder 105 with a pivot mechanism 106, a lamp holder 107 with integral lens retention spring, a wedge-base lamp holder 108, a rotation lock light fixture 109 with a pivot mechanism 110, and a feed 111.

#The track light system 100 may be operated at various voltages. For example, the track light system may be operated at 24 volts and 25 amps (600 watts) or at 12 volts and 25 amps (300 watts). Operating at these voltages, the track light system 100 does not require grounding. The track light system 100 may be operated with a variety of power supplies. For example, the track light system 100 may be operated with 60, 150, or 300 watt electronic power supplies, or with 150, 300, 600, or 1200 watt magnetic power supplies. Power supplies may be designed for operation at various input voltages, such as, for example, 120 volts or 277 volts, with alternating current feed.

#Electronic power supplies are lightweight and relatively small, allowing their use in cabinets and confined areas. Power supplies are designed for tie-in to existing feed locations and can be placed at the start of the track network 101 or at any point along the track network 101.
