Referring now to FIGS. 1 and 2, a door assembly 10 having a door frame 30 is described in accordance with embodiments of the present disclosure. The door frame 30 defines a doorway 32 that allows passage through the door frame 30. In some embodiments, the door frame 30 defines the doorway 32 between an interior and an exterior of a structure to allow ingress into or egress from the structure through the doorway 32. A door 50 secures to the door frame 30 and moves between an open position (FIG. 2) and a closed position (FIG. 1). When the door 50 is in the open position passage through the door frame 30 is allowed. When the door 50 is in the closed position the door 50 fills the doorway 32 and restricts passage through the door frame 30. The door frame 30 has a first side 12 and a second side 14 that may be an interior side and an exterior side, respectively. The first side 12 of the door frame 30 and the second side 14 of the door frame 30 are spaced apart by a thickness of the door frame 30. The door 50 may secure to the door frame 30 on the first side 12 or the second side 14 of the door frame 30. The door 50 may be a hinged door or a pivot door.

The door frame 30 includes a header 34, a pair of jambs 36, and a sill 38. The header 34, the jambs 36, and the sill 38 define the doorway 32. In some embodiments, the door frame 30 includes a stop 40. In embodiments where the door frame 30 has a stop 40, the stop 40 engages the door 50 when the door 50 is in the closed position to prevent the door 50 from passing entirely through the doorway 32. In some embodiments, the door frame 30 may be provided without a stop 40, e.g., when the door 50 is a pivot door. A portion of the stop 40 projects from each of the header 34 and the jambs 36 into the doorway 32. The stop 40 has an interior side 42 and an exterior side 44 corresponding to the first side 12 and the second side 14 of the door frame 30. The interior side 42 of the stop 40 and the exterior side 44 of the stop 40 are spaced apart by a thickness of the stop 40. When door 50 is in the closed position an exterior face 54 of the door 50 engages the interior side 42 of the stop 40. In some embodiments, the interior side 42 of the stop 40 includes weather stripping to form a weather resistant seal between the interior side 42 of the stop 40 and the exterior face 54 of the door 50 around the perimeter of the doorway 32.

With additional reference to FIGS. 3-5, the door frame 30 includes a light fixture 60 secured to the header 34 to illuminate the doorway 32. The light fixture 60 may be disposed within the header 34 or may be mounted to a surface of the header 34. The light fixture 60 may be positioned in the header 34 between the first side 12 and the second side 14 of the door frame 30. In embodiments, the light fixture 60 may be positioned in the stop 40 of the header 34 between the interior side 42 and the exterior side 44 of the stop 40. In some embodiments, the light fixture 60 is secured to the header 34 between the second side 14 of the door frame 30 and the exterior side 44 of the stop 40. As shown in FIG. 4, the light fixture 60 may extend substantially the width of the header 34. The light fixture 60 may have an outer surface 67 and may be disposed within the header 34 such that the outer surface 67 is substantially flush with a bottom surface 46 of the header 34, as shown in FIG. 5. In embodiments, the light fixture 60 is positioned within a recess defined within the header 34. In some embodiments, the light fixture 60 is secured to the bottom surface 46 such that the light fixture 60 protrudes from the bottom surface 46 such that the outer surface 67 is not flush with the bottom surface 46. In certain embodiments, a portion of the light fixture 60 is disposed within or mounted to one of the jambs 36. In particular embodiments, the door frame 30 includes more than one light fixture 60. Each light fixture 60 may be disposed in or mounted to the same member of the door frame 30, e.g., three of the light fixtures 60 may be in the header 34 or a jamb 36, or the light fixtures 60 may be disposed in a different member of the door frame 30, e.g., one light fixture 60 disposed within the header 34 and one light fixture 60 disposed within each of the jambs 36.

The light fixture 60 may be provided as part of the door assembly 10 for installation during construction or remodeling of a structure. In the case of existing structures, the light fixture 60 may be secured to the header 34 of an existing door frame 30. In embodiments, a recess is cut into the header 34 of an existing door frame 30 to receive the light fixture 60. The light fixture 60 may have rounded or arcuate end segments 64a, 64b to eliminate the need for the recess to have sharp internal corners cut into to the ends of the recess. In some embodiments, the light fixture 60 is surface mounted to the header 34. The light fixture 60 may be surface mounted to the header 34 by fasteners, e.g., screws. The light fixture 60 may be sized and dimensioned to fill the space along the header 34 defined between the exterior side 44 of the stop 40 and the second side 14 of the door frame 30 such that the outer surface 67 of the light fixture 60 is flush with the stop 40.

The plugs 84 may seal the case 80 to protect the electronics stored in the case 80 from moisture and debris.

With particular reference to FIG. 4, in embodiments where the battery 68 is disposed outside the light fixture 60, the door assembly 10 may include an access box 69 mounted within the wall of a structure near the door frame 30. For example, the access box 69 may be positioned above the header 34 as shown. The access box 69 may provide access to the battery 68 and other components, e.g., the controller 65, for maintenance or installation of other accessories. The sensors 62, 66 may be accessed and replaced from within the access box 69. The access box 69 may facilitate serviceability of the light fixture 60.

Continuing to refer to FIGS. 3-6, the functions of the sensors 62, 66 are described in accordance with embodiments of the present disclosure. In embodiments, the first sensor 62 is a motion sensor or proximity sensor and the second sensor 66 is a light level sensor such that the light fixture 60 may switch to the on-state in response to a user approaching the second side 14 of the door frame 30 or when ambient light drops below a threshold on-level. The threshold on-level may be the ambient light level at sunset, e.g., approximately 300-500 lux. In some embodiments, the first sensor 62 is a motion sensor or proximity sensor and the second sensor 66 is a light level sensor such that the light fixture 60 switches to the on-state in response to a user approaching the second side 14 of the door frame 30 only when ambient light drops below a threshold on-level. The light fixture 60 may switch to the off-state after a predetermined duration without motion sensed by the first sensor 62 or after a specified duration after the second sensor 66 senses ambient light levels below the threshold on-level. The light fixture 60 may switch to the off-state in response to the second sensor 66 sensing ambient light above a threshold off-level. The threshold off-level may be the ambient light level at sunrise, e.g., approximately 300-500 lux. The predetermined duration without motion sensed by the first sensor 62 may be in the range of a few seconds to several minutes, e.g., 5-seconds, 30-second, I-minute, 5-minutes, or more than 5-minutes. The specified duration after the second sensor 66 senses ambient light levels below a threshold on-level may be in the range of a few seconds to several hours, e.g., 30-seconds to 12-hours, or the specified duration may end at a specified time of day, e.g., midnight. In certain embodiments, the light fixture 60 may be controlled remotely from a computer or a cell phone through Wi-Fi, Bluetooth®, or telecommunications modules (e.g., 3G, 4G, 5G) to switch the light fixture 60 between the off-state and the on-state or to set the predetermined and specified durations for a respective sensor 62, 66.

Additionally or alternatively, switching of the light fixture 60 to the on-state in response to motion sensed by the first sensor 62 may be limited to when the second sensor 66 contemporaneously senses ambient light levels below a threshold on-level. Controlling the light fixture 60 by input from both the first sensor 62 and the second sensor 66 may conserve power usage and/or extend the life of the battery 68 by preventing the light fixture 60 from switching to the on-state during daylight hours. As noted above, the first sensor 62 or the second sensor 66 may project from a respective end segment 64a, 64b. In this example, projection of the first sensor 62 from the first end segment 64a may increase the sensory field of the first sensor 62, allowing for detection of motion a greater distance from the second side 14 of the door frame 30.

In some embodiments, the light fixture 60 switches to the on-state in response to the position of the door 50. When the door 50 is moved to the open position the light fixture 60 may switch to the on-state. In such embodiments, the light fixture 60 may switch to the on-state independently of input from the first sensor 62 or the second sensor 66. In particular embodiments, the light fixture 60 switches to the on-state in response to operation of a lock 56 of the door 50. Transitioning the lock 56 to an unlocked configuration may switch the light fixture 60 to the on-state. In some embodiments, the light fixture 60 is manually operable by a wall switch on the first side 12 of the door frame 30. In certain embodiments, the light fixture 60 may supplement or replace exterior lighting.

In embodiments, the light fixture 60 may include a microphone, speakers, and a camera in communication with one another to act as an intercom system allowing for communication of users across the door assembly 10 or monitoring of activity near the door assembly 10. The microphone may detect and operate the light fixture 60 in response to specific sounds. In embodiments, a user speaking a phrase such as “light on” or “light off” may be detected by the microphone and may switch the light element 61 between the on-state and the off-state. Such embodiments may allow for control of the light fixture 60 before a sensor 62, 66 detects motion of an approaching user.

In some embodiments, the light fixture 60 includes a thermal sensor that may detect an approaching user to control the light element 61. The thermal sensor may be configured to control the light element 61 in response to detection of a particular thermal signature to reduce unnecessary activation of the light element 61. The thermal signature may be based on the size of the thermal signature or the temperature of the thermal signature, e.g., human sized or human body temperature.

With reference to FIG. 7, in some embodiments the light fixture 60 is installed in the frame of an interior door frame 130 to illuminate the doorway 132. The interior door frame 130 includes a header 134 and jambs 136. The light fixture 60 may be disposed in the header 134. The interior door frame 130 may include a door or may be a framed opening without a door as shown. The sensors 62, 66 of the light fixture 60 may detect motion on a singular side of the interior door frame 130 or both sides of the interior door frame 130. In certain embodiments, several light fixtures 60 may be in signal communication with each other such that as a user move through a structure, from one room to another room, the several light fixtures 60 switch between the on-state and the off-state to illuminate the path of the user through the structure. The light fixture 60 may be oriented to illuminate a single side of the interior door frame 130 or both sides of the interior door frame 130. For example, the interior door frame 130 may be the door frame of a closet and the light fixture may be oriented to illuminate the interior of the closet.

Referring to FIG. 8, the door assembly 10 may include solar panels 70 that are in electrical communication with the light fixture 60. The solar panels 70 may be electrically coupled to the battery 68 to charge the battery 68 of the light fixture 60 or may be electrically coupled to the light element 61 to deliver electrical energy directly. The solar panels 70 may be integrated into the door 50 or may part of a sidelight or window of the door assembly 10. In some embodiments, the solar panels 70 may be disposed on a wall or placed adjacent the door assembly 10. Inclusion of solar panels 70 may be particularly desirable where the door assembly 10 receives direct sunlight for several hours per day, e.g., where the door assembly 10 is south-facing in the northern hemisphere.

Referring back to FIGS. 1 and 2, in particular embodiments, the door frame 30 may be a powered door assembly including an energy transfer device and electrical components. The energy transfer device may transfer electrical energy and/or signals between the door frame 30 and the door 50.
