MOTION SENSOR LIGHT APPARATUS
This invention relates to a motion sensor light apparatus.
It is known to use a motion sensor light to illuminate an area only when it is required so as to save on power consumption of the lighting apparatus. Use of such motion sensor lights can also provide security benefits by illuminating movement of a person trespassing.
According to a first aspect of the invention there is provided a motion sensor lighting apparatus connected in use to a power source via a power switch, the motion sensor lighting apparatus comprising: a housing; a motion sensor configured to detect the presence and/or movement of an object within a field of view and to output a control signal upon such detection; a primary light emitting device configured to illuminate a target area when switched on; an indicator light emitting device visible external to the housing; a control circuit electrically coupled to the motion sensor and to the primary zo light emitting device, and being configured to operate the primary light emitting device in a sensor mode and an override mode, wherein in the sensor mode the primary light emitting device is switched on based on the control circuit receiving the control signal from the motion sensor and is configured to turn off the primary light emitting device after a predetermined time, wherein in the override on mode the primary light emitting device is switched to on regardless of the control signal from the motion sensor; the control circuit being further electrically coupled to the indicator light emitting device and configured to switch the indicator light emitting device on when operating in the override on mode.
The inclusion of such a motion sensor means that illumination provided by the primary light emitting device is triggered by the presence or movement of an object, e.g. a person or animal, thus providing illumination to a target area when required or desired.
Meanwhile, the control circuit being configured to operate the primary light emitting device in an override on mode means that the sensor mode can be overridden such that the illumination provided by the primary light emitting device stays on (i.e. is "permanently" on regardless of the motion sensor being triggered by the presence or movement of an objection). "Permanently" in this context is understood to mean that the primary light emitting device stays on while operating in the override on mode until this mode is changed. Having such an override on mode allows a user to have continuous illumination which is not disturbed due to the lack of presence or movement of an object. For example, the motion sensor lighting apparatus may be used as a floodlight/security light in a domestic garden and during a social gathering it is undesirable for the light to keep switching off because it does not detect movement of people.
Moreover, the indicator light emitting device being controlled by the control circuit to switch on (i.e. light up) when the control circuit is operating in the override on mode and the indicator light emitting device being visible external to the housing, means that a visual indication is provided to the user what mode the motion sensor lighting apparatus is operating. This, in turn, prevents confusion as to which mode the motion sensor lighting apparatus is operating and also serves as a reminder to the user to put the motion sensor lighting apparatus back into sensor mode once the continuous illumination is no longer required. Otherwise, a user may not be certain which mode the motion sensor lighting apparatus is operating and would have to wait out of range of the motion sensor to see whether or not the illumination stops to check what mode the apparatus is operating. This is inconvenient and it is easily forgotten about, resulting in the motion sensor lighting apparatus being left permanently on when it does not need to be.
Preferably the control circuit is configured to operate in the override on mode upon receiving a first switching pattern signal from the power switch in use.
Optionally the control circuit is configured to operate in the sensor mode upon receiving a second switching pattern signal from the power switch in use.
The use of such switching patterns provides a convenient way for a user to change the mode of the motion sensor light apparatus.
The control circuit may be configured to switch the indicator light emitting device off when operating in the sensor mode.
Such an arrangement means that the indicator light emitting device is automatically switched off when the control circuit changes from the operating in the override on mode to the sensor mode without requiring further input from the user.
Optionally, the control circuit is configured to operate in an override off mode in which the primary light emitting device is switched to permanently off regardless of the control signal from the motion sensor.
The control circuit being able to operate in an override off mode means that no illumination is provided regardless of the motion sensor being triggered, and thus a user can use this mode when no illumination is required or desired.
The control circuit may be configured to switch the indicator light emitting device on when operating in the override off mode.
As outlined above, the indicator light emitting device provides a visual indication and reminder to the user that the motion sensor lighting apparatus is operating in an override mode (and not the sensor mode).
Optionally, the indicator light emitting device is configured to have different light characteristic outputs for the override on mode and the override off mode.
Such an arrangement makes it clear to the user which override mode the motion sensor lighting apparatus is operating in. This may be especially important if there is a problem with the primary light emitting device, e.g. it has stopped illuminating, such that it is not clear to the user which mode the apparatus is currently operating in.
The motion sensor may be one of: an infrared sensor or a microwave sensor.
A preferred embodiment of the invention will now be described, by way of a non-limiting example, with reference to the accompanying drawing in which: Figure 1 is a schematic circuit diagram of the motion sensor lighting apparatus according to the invention.
The motion sensor lighting apparatus 10 is shown connected to a power source 12 via a power switch 14. In this embodiment, the power source is mains power and the motion sensor lighting apparatus 10 is a security light that is installed on the outside of a domestic building (not shown). In other embodiments, the power source may instead be batteries.
The motion sensor lighting apparatus 10 includes a motion sensor 16, a primary light emitting device 18, an indicator light emitting device 20 and a control circuit 22. The apparatus 10 also includes a housing 24 which houses the aforementioned components.
The motion sensor 16 is configured to detect the presence and/or movement of an object within a field of view. In this embodiment, the motion sensor 16 is an infrared sensor and more particularly is a passive infrared sensor (PIR or MD). In other embodiments, the motion sensor may be take any other suitable form such as a microwave sensor (which uses continuous weaves of microwave radiation to detect motion).
The motion sensor 16 is also configured to output a control signal upon detection of the presence and/or movement of an object.
The primary light emitting device 18 is configured to illuminate a target area when it is switched on and is therefore positioned within the housing 24 to permit this functionality. The primary light emitting device 18 is the main light source which provides the illumination functionality of the apparatus 10. The primary light emitting device 18 is an array of LEDs 26. In other embodiments, the primary light emitting device 18 may instead be any other suitable light bulb, such as an incandescent, halogen or compact fluorescent (CFL) light bulb.
The indicator light emitting device 20 is visible external to the housing 24 and is therefore positioned within or on the housing 24 to permit this. For example, the indicator light emitting device 20 may be positioned inside the housing 24 with an appropriate window (not shown) to allow the indicator light emitting device 20 to be seen externally. The window may additionally include optical components to influence the light from the indicator light emitting device 20, e.g. diffuse, focus and/or strengthen the light. The indicator light emitting device 20 may instead be positioned on the outer surface of the housing 24 so that it is visible externally.
The control circuit 22 is electrically coupled to the motion sensor 16 and to the primary light emitting device 18. The control circuit 22 is configured to operate the primary light emitting device 18 in a sensor mode and an override mode. In the sensor mode, the primary light emitting device 18 is switched on based on the control circuit 22 receiving the control signal from the motion sensor 16 and is configured to turn off the primary light emitting device 18 after a predetermined time. In other words, in the sensor mode, illumination provided by the primary light emitting device 18 is triggered by the presence and/or movement of an objection as detected by the motion sensor 16. The primary light emitting device 18 stays on for a predetermined amount of time then it is switched off, unless a further detection of presence and/or movement of an object occurs. The predetermined amount of time may be any suitable time and may be chosen or programmed by the user or at manufacture depending on the intended purpose of the motion sensor lighting apparatus 10. For example it may be somewhere in the region of 30 seconds or it may be somewhere in the region of 30 minutes.
In the override on mode, the primary light emitting device 18 is switched to on regardless of the control signal from the motion sensor 16. In other words, the illumination provided by the primary light emitting device 18 is continuously provided and not interrupted by the absence of movement detected by the motion sensor.
The control circuit 22 is further electrically coupled to the indicator light emitting device 20 and is configured to switch the indicator light emitting device 20 on when operating in the override on mode.
In the embodiment shown, the control circuit 22 includes an integrated circuit which is programmed to carry out the actions outlined above.
The motion sensor apparatus 10 also includes a relay 28 connected between the control circuit 22 and the primary and indicator light emitting devices 18, 20 for providing switching functionality during use. The motion sensor apparatus 10 further includes a power supply circuit 30 that is configured to provide the appropriate AC and DC voltages for operation of the primary light emitting device 18.
The motion sensor lighting apparatus 10 may be used in or with microwave sensors, floodlights, security lights, PIR's in general, wall mounted sensors, ceiling mounted and surface mounted sensors.
In use, the motion sensor lighting apparatus 10 is installed in an appropriate place to allow illumination of or onto a target area by the primary light emitting device 18. For example, the motion sensor lighting apparatus 10 may be installed on an outside wall of a domestic building to illuminate a portion of the garden.
When the control circuit 22 is operating in the sensor mode, the motion sensor 16 will detect the presence and/or movement of a person or animal in the garden which triggers the motion sensor 16 to output a control signal. The control signal is received by the control circuit 22. The control circuit 22 (in particular, the integrated circuit) processes the control signal and actuates the switch on of the primary light emitting device 18. The primary light emitting device 18 is switched on to provide illumination to the garden. The primary light emitting device 18 stays switched on for a set time period, such as 60 seconds. If the motion sensor 16 does not detect any further presence or movement of an object within this time, then the primary light emitting device 18 turns off automatically, thus illumination of the garden is ceased. If, however, a person/animal moves around in the garden (as long as it is still in the field of view of the motion sensor 16), then the control signal is again triggered such that the control circuit 22 switches on the primary light emitting device 18, which maintains the illumination provided to the garden.
In circumstances where it is desirable to maintain illumination of the garden without the light going on and off (or having to maintain movement within the field of view of the motion sensor 16), then the override on mode can be activated. Such situations might be an evening social gathering in the garden where people might be motionless for long periods of time (e.g. sitting down conversing) such that the motion sensor 16 would not be triggered and thus the primary light emitting device 18 would turn off.
To activate the override on mode, the user switches a main power switch (e.g. the wall switch if the apparatus 10 is integrated into mains or the local power switch on the apparatus 10 if not or alternatively via a remote control) on and off in a pre-set pattern. For example, switching it on and off twice within 3 seconds.
In the override on mode, the control circuit 22 latches the motion sensor 16 to "on" such that the primary light emitting device 18 stays on and the illumination of the garden is maintained regardless of the lack of motion detected by the motion sensor 16. At the same time, the control circuit 22 controls the indicator light emitting device 20 to turn it on, thus providing a visual indication to the user that the override on mode is activated. In this example, the indicator light emitting device may be green.
Once continuous illumination of the garden is no longer required, e.g. because the gathering is over and everyone has vacated the garden, the sensor mode may be reactivated. To reactivate the sensor mode, the user switches a main power switch (e.g. the wall switch if the apparatus 10 is integrated into mains or the local power switch on the apparatus 10 if not or alternatively via a remote control) on and off in a pre-set pattern. For example, switching it off for 5 seconds then on again. This results in the control circuit operating in the sensor mode in the same manner as outlined above.
In circumstances where it is desirable to completely cease illumination of the garden without the light being triggered to switch on, then the override off mode can be activated.
To activate the override off mode, the user switches a main power switch (e.g. the wall switch if the apparatus 10 is integrated into mains or the local power switch on the apparatus 10 if not or alternatively via a remote control) on and off in a pre-set pattern.
For example, switching it on and off three times within 5 seconds.
In the override off mode, the control circuit 22 latches the motion sensor 16 to "off" such that the primary light emitting device 18 stays off and the illumination of the garden is ceased regardless of motion detected by the motion sensor 16. At the same time, the control circuit 22 controls the indicator light emitting device 20 to turn it on, thus providing a visual indication to the user that the override mode is activated. This time, the indicator light emitting device 20 is red to distinguish between the override on and override off modes.
In other embodiments, a switch pattern by the user is not required in order to activate a mode. Instead, for example, there may be an option to simply select a mode via a smart device such as a mobile phone or tablet, or via a user interface installed on a remote or display integrated into the wall, which communicates with the control circuit via wireless communication (e.g. WiFi).
