Abstract
A door handle device includes pathway lighting to illuminate a pathway when needed, such as during a power outage, fire, or other emergency. The pathway lighting includes at least one light source, such as a super-bright LED or other low current/power light source, that is mounted to a door and that is bright enough to illuminate a pathway. Power for the light source may be provided by an internal power source that is used to power other components (e.g., a lock, a key card reader, etc.) within the door handle device. The pathway lighting acts as a backup or supplemental light source when needed to guide people toward a desired location. The pathway lighting may also act as an interior light.
Description
- The present invention relates generally to door handle assemblies.
- Currently-used hotel room doors incorporate special door handle assemblies rather than the doorknobs used in conventional doorknobs normally found in residences. These door assemblies often incorporate electronic circuitry, such as an electronic key card reader, electronic latches, and other devices.
- There are situations where there is insufficient lighting to locate the door handle, such as at nighttime, during a power outage, in the case of fire, etc. Although it may be possible to direct supplemental lighting to illuminate the door handle, the lighting will also lose power in the case of a power outage if it is connected to a central source, making it ineffective in emergency situations where there is a power loss. Moreover, there is currently no way to provide pathway lighting in emergency situations, nor is there any way to control lighting to respond to environmental conditions, such as a change in the amount of ambient light near the door handle assemblies. Conventional lighting used to illuminate the door handle itself may provide enough lighting for locating the door handle in darkened conditions, but it is insufficient to illuminate any area beyond the immediate vicinity of the door handle.
- There is a desire for a device that provides a way to illuminate a pathway in the event of a power outage or other situation requiring supplemental lighting.
- The invention is generally directed to a door handle device incorporating pathway lighting to illuminate a pathway when needed, such as during a power outage, fire, or other emergency. In one embodiment, the device includes at least one light source, such as a super-bright LED or other low current/power light source, that is mounted to a door and that is bright enough to illuminate a pathway. Power for the light source may be provided by an internal power source that is used to power other components (e.g., a lock, a key card reader, etc.) within the door handle device. In one embodiment, the device also includes a light sensor that detects the amount of ambient light surrounding the device and a controller that controls the operation of the light source based on the amount of ambient light.
- By providing pathway lighting on the door handle device, the invention can illuminate a pathway in situations where other light sources are unavailable. As a result, the pathway lighting provides an additional measure of comfort to guide users toward the door and lead them toward a desired location, if needed, in the event that normal lighting is unavailable. The pathway lighting may also act as interior lighting to provide emergency lighting and/or act as a nightlight.

FIG. 2 is a rear perspective view of a door handle device ofFIG. 1 according to another embodiment of the invention; -
FIG. 3 is a representative diagram of a control unit in the door handle device according to one embodiment of the invention; and -
FIG. 4 is a representative diagram of a control unit in the door handle device according to another embodiment of the invention. -
FIG. 1 illustrates a front portion of adoor handle device 100 according to one embodiment of the invention. In this description, the term “front” corresponds to the portion of thedoor handle device 100 that is on the exterior portion of the door (e.g., facing into a hallway), while the term “rear” or “back” corresponds to the portion of the door that is on the interior portion of the door (e.g., facing into a hotel room). - In the example shown in
FIG. 1 , thedoor handle device 100 includes adoor handle 102 and aface plate 104. Theface plate 104 may include aslot 106 or other opening for accommodating an electronic key (not shown).Indicator lights 108 may be included in thedevice 100 to provide visual feedback to a user to indicate whether or not the key card is inserted correctly into theslot 106. - To illuminate a pathway in the vicinity of the
door handle device 100, thedevice 100 includes at least onelight source 110. Thelight source 110 itself may be any light source that runs on low current/power and that can produce light with enough brightness to illuminate a pathway. Possible light sources include, for example, LEDs, electro-luminescent light sources, incandescent lights, etc. In the illustrated example, thelight source 110 is amodule 112 containing a plurality ofsuper-bright LEDs 114. As shown inFIG. 3 , thelight source 110 may obtain its power from, for example, aninternal power source 116 within thedevice 100 that is also used to power other components within thedevice 100, such as akey card reader 118, a latch (not shown), or locking mechanisms (not shown) in the door. Connecting thelight source 110 with aninternal power source 116 used within the door rather than an external centralized power source ensures that thelight source 110 can be used for emergency lighting in the event of an emergency, power outage, or other similar occurrence requiring supplemental lighting. - Note that the
light source 110 is not used simply to illuminate thedoor handle 100 and therefore cannot simply be, for example, a low-wattage incandescent light. Instead, thelight source 110 should be bright enough so that thelight sources 110 on multiple doors in a hallway, for example, delineate a pathway that can be easily seen and followed in an emergency situation even if there is no other available ambient lighting. For example, thelight sources 110 may define and illuminate a pathway that leads toward an exit. - In one embodiment, as shown in
FIG. 3 , thedevice 100 includes acontrol unit 118 that is manually operable or has an electronic eye or othersimilar light sensor 120 that detects the amount of ambient light surrounding thedevice 100. Thedevice 100 also includes aswitch 122 that controls operation of thelight source 110 based on the detected amount of ambient light. For example, theswitch 122 may be controlled to provide infinite adjustment of the light intensity output by thelight source 110 based on the amount of ambient light (e.g., decreasing the brightness of thelight source 110 when ambient light level is high and increasing the brightness of thelight source 110 sufficiently to illuminate the pathway when the ambient light level drops below a selected threshold). Alternatively, theswitch 122 may simply cause thelight source 110 to turn on only when thelight sensor 120 detects that the ambient light drops below the threshold; in this case, thelight source 110 would remain turned off at all other times. - As shown in
FIG. 2 , alight source 110 a may be mounted on the rear side of the door as well as or instead of the front side of the door. When thelight source 110 a is mounted on the rear side of the door to face, for example, an inside of a hotel room, thelight source 110 a can act as a night light or beacon so that a person can easily find thedoor handle 102 in a darkened room. Moreover, because thelight source 110 a can be adjusted to output light having an intensity that is high to illuminate a pathway, theinventive device 100 provides an additional measure of safety to hotel room occupants. Note that incorporating thelight sensor 120 to control operation of thelight source 110 a in this embodiment can allow the light intensity to be reduced if, for example, thelight source 110 a is to be used only as a night light in non-emergency situations. Note that although the embodiment shown inFIG. 2 shows thelight source 110 a pointing upward, thelight source 110 a may be arranged to point downward to illuminate thedoor handle 102 from above instead. - The control unit used to power and control operation of the
light source 110 a in the embodiment shown inFIG. 2 is the same as the one described above with respect toFIG. 3 . Note that a single given door may have thedevice 100 having the embodiment shown inFIG. 1 , the embodiment shown inFIG. 2 , or both. If the door has a light source on both itsfront side 110 and itsrear side 110 a, thesame control unit 118 may be used to control operation of bothlight sources - Further, the
control unit 118 may be configured so that thelight sources FIG. 4 , thecontrol unit 118 may also include acontroller 124 that controls the twolight sources respective light sensors controller 122 turns thefront light source 110 off when itscorresponding light sensor 120 detects light in a hallway, while thecontroller 122 also turns therear light source 110 a on when itscorresponding light sensor 120 a detects that the hotel room is darkened. In both cases, thelight sources 110 a , 110 b illuminate and define a pathway in the vicinity of thelight source 110 a , 110 b due to their brightness. - Instead of or in addition to the
sensors receiver 126 may be connected to theswitch 122 or thecontroller 124 to receive a wireless message from, for example, a wireless messenger communication system (not shown). In this case, the message received by thereceiver 126 acts as the control mechanism. The message may instruct theswitch 122 orcontroller 124 to enable or disable thelight source 110, 10 a; in one example, in the case of a power outage, the messenger system can send a last message to turn on thelight source light source - Incorporating a light source to serve as pathway lighting for a door handle device and powering the light source with a power source associated with the door itself provides a reliable, economical way to offer supplemental lighting in emergency situations. Moreover, controlling the intensity of the light output from the light source based on a detected amount of ambient light allows more efficient operation of the light source with minimized current draw.
