The disclosure concerns a controlling device for the turning on, turning off and adjustment of the light intensity of a lighting system comprising at least one light fitting.
Currently, controlling devices are known that use an adjusting button connected to a potentiometer for controlling the light intensity level of a light fitting. Thus, a user can adjust the level of lighting by rotating said button. This button can be pressed by a user to turn on or turn off said light fitting. Additionally, this controlling device can have a control unit that can comprise memorized light levels.
Even though these devices function correctly, they penalize the control of the light intensity level compared to the turning on and turning off function, such that the user intuitively uses the device as a simple switching without using the light intensity control function.
Furthermore, these devices from the state of the art do not adjust and indicate the level of lighting at which the light fitting is set when it is turned off as well as turned on.
The present disclosure relates to a controlling device for controlling a lighting system comprising at least one light fitting, wherein said controlling device is linked with said lighting system and comprises:
Additionally, the controlling device comprises an electrical connection, heat dissipation elements and a casing that protects it and provides connection means for its integration in a box able to be flush-mounted, preferably, in a wall or in a surface box.
The switching mechanism and the adjusting mechanism are actuated by means of the actuation of the user on the same means, namely the interface of the controlling device. Preferably, this interface is the actuation surface of a rocker key.
More specifically, the switching mechanism comprises a switch with two states that allows for, according to the open or closed state thereof, the electrical powering of the lighting. The user, by means of applying a pressure to the interface, causes the switch between the open and closed states of the switching.
The interface comprises at least a sensor, and preferably comprises two sensors that are preferably capacitive sensors that are housed in the inner surface of the interface, such that the capacitive sensors occupy the majority of the inner surface of the interface. These two capacitive sensors are able to produce an essentially linear analog adjusting signal. This analog adjusting signal changes based on a linear movement parallel to the controlling device, performed by the user throughout the outer upper surface of the interface. The analog adjusting signal in each point of the length of the surface of the interface is related to a light intensity such that the actuation of the user on a point of the length of the surface of the interface makes it so that the capacitive sensors transmit to the control unit of the adjusting mechanism a signal that is determined and related to a specific light intensity.
It is worth noting that the control unit comprises a first microcontroller that in turn comprises at least an analog/digital converter for converting said analog adjusting signal to a digital one.
Thus, the first microcontroller transmits a digital signal so that the lighting system provides the light intensity according to this signal, in the case in which it is turned on or so that it has a starting light intensity when it is turned on.
It is worth noting that the actuation performed by the user on the interface can be by means of the contact on it or by means of the positioning thereof at a close distance approximately perpendicular to said surface.
Preferably, the interface additionally comprises an indicating mechanism linked to the adjusting mechanism and intended to continuously show the light intensity of the lighting system to the user.
This indicating mechanism comprises a plurality of LEDs also controlled by the control unit of the adjusting mechanism in order to be turned on linearly depending on the signal related to the light intensity provided by the capacitive sensors, the light system being turned on or turned off.
In a preferred embodiment, the indicating mechanism comprises means that cause signals such as sounds, scents, vibrations . . .
Preferably the indicating mechanism is in the interface.
Preferably, the controlling device further comprises a wireless communication mechanism. More specifically, this wireless communication mechanism is linked to the first microcontroller of the control unit of the adjusting mechanism, and comprises a radio frequency antenna and a radio frequency module, the antenna being adjacent to the previously described capacitive sensor. In this way, the assembly of the capacitive sensor and the antenna occupy the entirety of the inner surface of the interface. Preferably, both are integrated in a PCB or directly printed on the inner surface of the interface, more preferably they are printed on the inner surface of the actuation surface of a rocker key or are integrated in a PCB affixed to the inner surface of the actuation surface of the rocker key.
In the preferred embodiment in which the interface is the actuation surface of a rocker key, the communications module is preferably housed on the inside of the rocker key.
Preferably, the wireless communication module is connected to the control unit of the adjusting mechanism in order to enable the communication thereof with external mechanisms.
In a preferred embodiment of the disclosure, the interface is the actuation surface of an interchangeable rocker key that can connect and disconnect from a module integrated in the wall that comprises the switching and the electrical connections.
Thus, the present disclosure enables using the entirety of the surface of the interface both for adjusting the light intensity and for turning the light fitting on and off, integrating a functional portion like the antenna of the communication module and the sensors in an ornamental portion diminishing the size of the device.
Furthermore, the present disclosure enables adjusting and indicating the light intensity of the light fitting if it is turned on, and enables adjusting and indicating the starting light intensity while it is turned off.
As a complement to the description provided herein and for the purpose of helping to make the characteristics of the disclosure more readily understandable, in accordance with a preferred practical embodiment thereof, said description is accompanied by a set of drawings constituting an integral part of the same, which by way of illustration and not limitation represent the following:
The present disclosure, as shown in
The switching mechanism comprises a switch with two states that enables, according to the open or closed state thereof, the electrical powering of the lighting. More specifically, the switch is housed in an internal block of the controlling device (1), such that the state thereof depends on whether or not the rocker key (2) presses it, and in turn on whether or not the user has pressed said rocker key (2). Additionally, this internal block comprises the electrical connections with the light fitting and a casing that protects it.
The rocker key (2) comprises an outer surface (3) that is the interface of the controlling device (1) intended to receive the contact of the user, for example by means of the hand, a finger of a user or similar, for controlling the turning on and off of the light fitting, as well as for adjusting the intensity of the lighting.
More specifically, on the inside of the rocker key (2) a first printed circuit of polyamide with a thickness of 70 um is inserted which approximately occupies the entirety of the surface thereof. This printed circuit comprises an adjusting mechanism made up of two capacitive sensors and a radio frequency antenna, which makes up part of a wireless communication mechanism that further comprises a radio frequency module.
Alternatively, both the capacitive sensors and the radio frequency antenna are printed in the inner surface of the rocker key (2).
Thus, the user, upon sliding the hand, the finger or similar over said outer surface from one end towards the opposite end, usually from the left edge towards the right one, the capacitive sensors create, preferably, an analog adjusting signal, the value of which is increasing or decreasing depending on the movement and which is sent to an adjusting mechanism control unit.
More specifically, the capacitive sensors connect to the control unit comprising a first microcontroller endowed with an analog/digital converter that converts the analog adjusting signal into a digital one and processes it. Thus, the control unit enables, or interferes in, the passage of electrical current for determining the light intensity of the lighting system for all kinds of light fittings (reactive, capacitive or inductive).
Optionally, said radio frequency module of the communication mechanism manages the communications made by means of the radio frequency antenna with external elements by means of the Z-Wave protocol.
Preferably, the first microcontroller is inserted in the first printed circuit. Alternatively, it is inserted in a second printed circuit and linked to the first printed circuit by means of strips. This second printed circuit is housed in the rocker key (2).
Alternatively, this second printed circuit is housed in the internal block of the controlling device (1).
Additionally, this rocker key (2) in the outer surface thereof, in other words in the interface, comprises an indicating mechanism (6). This indicating mechanism (6) indicates to the user, regardless of whether the light fitting is turned on or off, the light intensity level of the light fitting, and is controlled by the first microcontroller comprised in the control unit.
Specifically, the indicating mechanism (6) comprises a series of LEDs arranged in a line, wherein a greater number of turned-on LEDs indicates a greater light intensity level of the light fitting from a minimum value to a maximum value.
More specifically, and in a non-limiting manner, the first microcontroller achieves that, upon sliding a finger over the surface of the interface from the left edge towards the right one, a first LED lights up and increases the intensity thereof until reaching a limit value that would be maintained at the same time as the intensity of the second LED also increases towards the limit value according to the movement of the finger passing along the surface of the rocker key (2), and in this way successively until the finger stops, or the last LED is lit up.
Additionally, the first microcontroller achieves that, when the lighting system is turned off, with the closeness or the contact of the user on the surface, the corresponding LEDs turn on indicating the starting intensity of the lighting system if the light fitting were turned on in that moment. Upon sliding the hand, the finger or similar from this starting intensity point towards one side or the other, the LEDs turn on or turn off, and correspondingly the intensity thereof is increased or decreased until the point in which the finger of the user stops.
Optionally, the wireless communication mechanism comprises a Wi-Fi type communications module.
