Abstract
A directional luminaire having a door frame, a lamp shroud, and a lampholder socket attached to a luminaire structure. The luminaire is wired, either directly or indirectly, to provide an electrical connection to a lampholder socket configured to receive a lamp. The lamp shroud has an opening from which the light output is directed. Further, the rim edge of the lamp shroud and retaining lip of the door frame interact to permit substantially complete rotation of the lamp shroud and lamp.
Claims18
A luminaire adapted for directional adjustment, comprising:
- a luminaire support structure;
- a door frame attached to the structure;
- a rotatable lamp shroud attached to the door frame wherein the lamp shroud has at least one opening;
- and
- a lamp socket within the lamp shroud, sized to received the base of a lamp, the lamp socket being electrically connected to a power source and having an electrical contact and being electrically connectable to the base of a lamp when the lamp base is inserted therein.
A method of installing a retrofit directional luminaire assembly in an existing luminaire, the retrofit directional luminaire having a door frame attached to a support structure, a rotatable lamp shroud attached to the door frame and a lamp socket disposed within the lamp shroud sized to receive a lamp, comprising:
- removing an existing door assembly from the support structure of the existing luminaire to expose the interior of the existing luminaire housing;
- removing any lamp and reflector from the structure;
- providing a door frame having a lamp shroud with at least one opening disposed therein;
- providing a lamp socket within the lamp shroud sized to receive the base of a lamp, the lamp socket being electrically connected to an electrical power source and being electrically connectable to the base of a lamp when the lamp base is inserted therein;
- providing a lens within the opening of the shroud;
- removably suspending the door frame in a substantially vertical, inoperative position;
- coupling a set of electrical leads from the power source to the lamp socket;
- pivoting the door frame to a horizontal, operative position whereby the door frame substantially closes against the structure;
- and
- securing the door frame in the horizontal, operative position.
A method of installing a retrofit directional luminaire assembly in an existing luminaire housing, the retrofit directional luminaire having a door frame attached to a support structure, a rotatable lamp shroud attached to the door frame, and a lamp socket disposed within the lamp shroud sized to receive a lamp, comprising:
- removing an existing door assembly from the luminaire support structure of the existing luminaire to expose the interior of the existing luminaire housing;
- removing any lamp and reflector from the structure;
- providing a door frame having a lamp shroud with at least one opening disposed therein;
- providing a lamp socket within the lamp shroud sized to received the base of a lamp, the lamp socket having an electrical contact being connected to an electrical power source and being electrically connectable to the base of a lamp when the lamp base is inserted therein;
- providing a lens within the opening of the shroud;
- removably suspending the door frame in a substantially vertical, inoperative position;
- coupling the existing housing lamp socket to the lamp socket using an adapter;
- pivoting the door frame to a horizontal, operative position whereby the door frame substantially closes against the structure;
- and
- securing the door frame in the horizontal, operative position.
A method of installing a luminaire assembly, having a door frame attached to a luminaire support structure, a rotatable lamp shroud attached to the door frame and a lamp socket disposed within the lamp shroud sized to receive a lamp, comprising:
- inserting the luminaire housing structure of the luminaire onto a horizontal support structure with the luminaire housing structure inserted from below the horizontal support structure upwardly into an opening in the horizontal support structure;
- engaging the luminaire housing structure with a temporary retainer on the horizontal support structure;
- holding the luminaire housing structure in the opening with the temporary retainer during installation of the luminaire;
- coupling the electrical connection on the lamp socket to an electrical power source;
- fixedly securing the luminaire housing structure to the horizontal support structure after the engaging and the holding steps;
- providing a door frame having a lamp shroud with at least one opening disposed therein;
- providing a lamp socket within the lamp shroud sized to received the base of a lamp, the lamp socket having an electrical contact and being electrically connectable to the base of a lamp when the lamp base is inserted therein;
- providing a lens within the opening of the shroud;
- removably suspending the door frame in a substantially vertical, inoperative position;
- coupling a set of electrical leads from an electrical power source to the lamp socket;
- pivoting the door frame to a horizontal, operative position whereby the door frame substantially closes against the luminaire housing structure;
- and
- securing the door frame in the horizontal, operative position.
