Description

DESCRIPTION

EMERGENCY LIGHTING DEVICE OF LED TECHNOLOGY OR EQUIVALENT, BASE FOR COMMON LIGHTING

The object of the present invention is an emergency lighting device, characterized by the use of LED-type lights or other similar illuminants, materialized on a circuit board or printed circuit (PCB), base to provide both lighting conventional, in which the circuit board can be presented fractionally in conveniently connected and operative parts together.

This function is performed by electrically feeding the network, as well as, the energy coming from a battery located inside the circuit. The presence of a microcontroller allows that a great variety of lighting effects can also be programmed that improve the information to be displayed through its lighting elements.

Sector of the technique

The invention disclosed relates to an emergency lighting device, which is now combined with the general one, with led-type luminaires or such improved technology, which, thanks to the presence of a microcontroller, can be programmed inside a great repertoire of effects in order to improve its effectiveness.

State of the art

In recent times the sensitivity of the population has increased in terms of security, especially as a result of episodes where the integrity and security of people in areas of public competition, have been severely compromised.

Equally, without reaching these extreme cases and related to the mass phenomena, daily life in the domestic and work environment are affected by the same so that some episodes can become authentic labyrinths for those affected and, even when there are security protocols and standards, they lose effectiveness if the victim is deprived of these references.

In this context, emergency lighting and evacuation systems, in charge of providing sufficient visibility and indications to allow an orderly leaving of an enclosure, are an essential measure that is being a focus of innovation in recent times. Its regulation is determined by national and European-level regulations that aim to establish a series of procedures to effectively maintain the safety lighting system in operation.

One of the drawbacks of its implementation is that when a project is in the execution phase, items such as emergency lighting, are sometimes considered secondary, reversing in an equipment installation that, being approved and ensuring regulatory compliance, they do not allow optimal monitoring, management and maintenance that will reduce these derived costs considerably.

Therefore, the challenge lies in being able to demonstrate that the most advanced security systems are fully compatible with adjusted and justified costs but for this it is necessary to increase the effectiveness of these mechanisms that, although they are based for example in the sense of seen, could be combined with other solutions that improve the evacuation routes reducing the consequences of a loss, if not avoiding them.

The relevance of the emergency luminaire on static signals, for example, is increasingly noticeable because technological advances lead it to be at the forefront of resources for the management of the risk of accidents and their incarnation.

Even though many of the new construction projects involve the implementation of more efficient, safer and lower cost systems of the emergency luminaire, this does not significantly affect the obsolete systems that are still installed, probably because these emergency systems are they see even as an uncomfortable obligation and an expense that, without wanting to anticipate it, can be useful in one of the most elemental situations of life, such as its preservation, and in a situation where visibility could be the difference between life and life. death. It would therefore be desirable for the emergency lighting system to be integrated into conventional lighting, which will avoid making differences that, in the end, favor its discrimination and encourage the reduction of the items destined for it.

Therefore, it is the purpose of the present invention not only to promote the increase of vision in a space aided by an emergency light, (usually equipped with incandescent or fluorescent lamps of poor visibility) but to provide said area with other benefits and resources that the make it safer for those affected by a risk situation, such as smoke detection or dangerous heat increase, indicator of the exit direction, indicator of the exact location of the emergency exit, actuator of an emergency door in certain situations, activator of fire sprinkler systems, emergency light variator of a conventional luminaire fed until then by the electric network, converter of the different luminaires (hitherto static) in a network of indicators of direction, location, actions to perform, etc., as it can serve to warn of calls or bells in noisy places or disabled people s. All this as a result of the efficient combination of the electronic elements that make up the circuit board or printed circuit (PCB). Also say that the light intensity or luminance obtained can be adjustable with what is easily suited to the area to be illuminated because in a small space, some excessive intensity, can be even dangerous.

In another of the possible functions of the printed circuit board, through the appropriate sensor, you could distinguish between night / day with the utility or the benefit that this could imply.

Description of the invention

The composition of this new emergency lighting system manages to solve the drawbacks and shortcomings described and not described as new solutions are provided so far not contemplated in a luminary, nor for the most basic assumptions that aim to ensure the safety and integrity of people .

The present invention refers in its base to a luminous emergency device which, as such, is embodied in a circuit board or PCB (Printed Circuit Board) having an area with light emitters, LED type or other compatible technology. future that adapts or replaces it with improvement, and on the other the electronics that allow its operation.

The position of the LEDs could be on the same side where the electronics reside, on the back face of the printed circuit or board and even on a separate piece making up the PCB as a set of two or more pieces communicated and not as an indivisible piece .

Said circuit board or printed circuit (PCB) is made without limitation in a specific way since it may adopt the one that adapts to the luminaire support that it is desired to reuse because its morphological versatility is one of its main characteristics, thereby contributing to the saving of time and money that supposes to reuse the supports of existing luminarias. Moreover, if the space that is counted is too small, the printed circuit board could be presented in a fractional version, in which they could be presented in an appropriate superimposed form to the available space and even distant, an electronic part inside the module box. light switching (for example) while the led diodes are integrated into a lamp socket serving for the communication of the same current wires, which is allowed to vary the location coordinates of the various electronic elements present without changing the connection between them.

In a non-limiting example, we take as reference the circuit board that we feed directly from the available electrical network, adjusting its output to provide the necessary electrical energy to the whole.

The power supply is of the switched type, which is prepared to work the different possible voltages, exempting it from human intervention for the possible changes of tension.

The indicated power system allows us to install the circuit board (PCB) as conventional light, reusing the same support, which will homologate it to become an emergency light in a negligible way when the failure or the absence of electric current occurs. To warn and confirm when it enters emergency mode, for example, the set will be or could be equipped with a pilot and even dim the intensity of the light since the transition will go unnoticed by the naked eye and it is advisable to warn the user that the dependence of the light is limited to the charge of the battery.

For this to be so, the set has an integrated load management circuit that is responsible for correctly managing the battery charge while an octocoupler, directly connected to the power supply and the microcontroller, will be responsible for supplying information on the input / interruption of the electric current to divert the consumption of the network to the battery and vice versa. The battery is guaranteed in this system a load reposition management to ensure maximum availability at all times.

The system has foreseen that the moment that passes between the step of being fed by the electric current to be fed by the battery and vice versa, the switching is covered or covered by the presence of a capacitor.

Finally we have a microcontroller to govern the main functions of lighting, as well as security and control, and the different effects that you want to produce with them through a driver.

The presence of communication ports on the printed circuit board allows us to guarantee the incorporation of important elements such as sensors and the PLC through which we can make an interaction of the device with the external environment through which certain events will be recognized. and it ensures that planned or planned events occur. These include the remote management that facilitates the execution of instructions at a distance by means of a control panel, interface or graphic window, being able to assign different orders that affect the whole set at the same time.

Of course, depending on the events that we want to reproduce, we will have present on the printed circuit board sensor detection night / night, smoke, heat, presence, phone call, movement, etc., enabling in this case its most convenient location within or not the structure of the luminaire.

As has been anticipated, with the composition of given elements and the proper programming of your microcontroller and other components needed, in a basic version, the most elementary events of alternation between common lighting and emergency lighting will be reproduced as well as , by means of any switch or commutator, to divide the intensity into multiple phases or between continuous light and off and on sequences, in order to reveal situations of exceptionality. All this manually in the absence of sensors and PLC.

The most advanced version that we have described from the beginning, is achieved through the presence of sensor devices, PLC and control panel or graphic window, all enabled by a computer application or software that serve as an interface between the operator and the devices. This software has in its programming with the different events that can be demanded, so that in a visual, intuitive and very fast way you can access and execute part or all of them.

The programming may or will include various effects of operation, influenced by the sensors above all, and which will be present both by a push button in the manual version and by an interface in the most advanced version. Among these effects we can find:

- Immediate and negligible input of the auxiliary supply by battery on the luminaire due to lack of supply of the electrical network, conserving the luminosity granted by the common supply.

- Illumination of pilot or any lighting disturbance that indicates the entry in auxiliary power mode due to the absence of the electric fluid of the common network.

- Changes in the intensity of the light or execution of series of on / off to alert on situations of danger detected by the different sensors that their communication ports allow to assign to the system.

- Execution of luminous signals composed of alternative ignition reactions that indicate direction of evacuation.

- Execution of lighting signals that can determine the place of the emergency exit through a signal different from the direction of evacuation, warning of undetermined danger, etc.

- Opening emergency exit doors before the crowds crowd on them and they can not be opened.

- Execution of light signals that allow people with hearing impairments to know when they ring the bell or telephone.

- Execution of light signals to warn when the battery approaches its exhaustion.

- Activation of an indicator that shows the correct recharge function and good battery status.

- Activation of acoustic signals parallel or independent of the aforementioned luminous signals.

- Activation of acoustic / luminous signs when detecting by activity alarm systems, either by power failure, fire, etc., to prevent, above all, persons physically disabled in any of their senses.

- Activation of the independent alarm system when the presence of any of the pre-established events is detected by sensors

- Etc.

Its great versatility allows it to act as a source of common light, emergency, as a portable light, as a signaling beacon, etc., and offers great advantages for its easy replacement and integration in the support of the conventional luminaire to which it comes to replace, by the unnecessary preparation required to replace it with another conventional one, by the practical use of any electric current to feed it, etc., which makes it an exceptional candidate for the replacement of luminaries in: military navigations or civil, spaces on surface or under surface, mines, public places and massive concurrence, underground or surface car parks with more than 100 m (where emergency lights are mandatory), large commercial areas, metro or train stations, streetlights and other public lighting, general toilets in buildings and commercial facilities, ... and, as a whole, principally, in spaces that require or require evacuation routes, due to their obligation, without neglecting spaces such as the domestic, the office, consultations, academies, etc., where a minimum of light is required and which allows to follow or finish orderly the activity that is being developed before cutting, especially if in addition the lack of supply is of short duration.

In all or some of the situations described above, such as, for example, in the case of an emergency light in a navlo, cover the circuit board with a thin layer of a protective varnish and be installed almost compulsorily in a watertight structure. , allows it to be thrown into the water as a position beacon to determine the place of an emergency or rescue, covering with it different but essential functions and that do not force to invest more resources or gather more material. The savings reported by this device is very considerable, in all respects, since it will extend its operation even to the interior of swimming pools, indoor fish farms, etc. In short, on practically all the spaces where the human being lives, works or develops any type of activity.

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a diagram is included as an integral part of said description, in which an illustrative and non-limiting character has been represented by a circuit in a valid configuration for all types of installations, from the most basic for an address or office, trade, etc., to those that respond to more extensive areas of public lighting or large spaces such as car parks, stadiums, theaters, venues in which concerts are given, etc., and where we can include special facilities such as naval vessels, oil tankers, transatlantic ships, etc.

In this diagram the different elements or components with which the circuit board or PCB is given are represented, having chosen a traditional representation in which one of the multiple figures that could describe its contour has been chosen: square, but that It could also be rectangular, hexagonal, triangular, circular and even be divided into several parts, so that one part could be hexagonal (where the electronics are contained, for example), while another part would be circular (where the LEDs are contained). Everything is a matter of adapting it to the space we want to reuse with this new device.

Essentially the diagram shows us the presence of a switched power supply, an integrated load management circuit, a microcontroller, a battery, an octo-coupler, a power switching relay, a configuration pushbutton,

a capacitor, fuses, a varistor, a mosfet, a PLC device, communication ports, sensors that connect to the communication ports, LED lighting and LED indicators of operation and the way in which they interact.

A preferred mode of realization

In view of the diagram, it can be interpreted that the constitution of a circuit board or printed circuit board (PCB) in a first non-limiting embodiment is composed of a switched power supply on which the power supply of the system mainly lies and which is directly connected to the electrical network, for which it has previous protection elements for overload, overvoltage, etc., such as a fuse and a varistor.

In order to grant the system a second source of alternate power, the circuit has a battery that assumes this role when the common electrical fluid is suspended.

This power supply provides current to a switching relay and to the rest of the components that make up the system, one of them being a led indicator that power is being operated by the electrical network.

In the same way, this switched source feeds an integrated charge management circuit for the battery with which the circuit board or PCB has in order to replenish its load when it is below the preset level and only when the system is powered exclusively by the switched source. This integrated circuit of load management is also responsible for managing the correct operating status of the battery by indicating it through a led indicator.

For the system to pass from one supply to another, from the switched source to the battery supply, the system is backed up with two elements: a switching relay and an octo-coupler.

The switching relay has the function of automatically and mechanically switching the position of its contacts when it stops receiving power from the power supply, to which it is directly connected, which leads the system to take the current of the battery. This absence of current affects the same way octocoplador that is also directly connected to the power supply, so when the power supply stops, the emitting infrared diode stops saturating the phototransistor causing a change that is detected by the microcontroller that then executes the part of the program dedicated to manage This state of supply, in the same way that it will happen the other way around when the common electrical power supply is restored.

During the brief switching interval, which is negligible, the power supply of the system is ensured by the participation of a condenser arranged to cover this task.

The microcontroller governs the printed circuit (PCB) for which it is in communication with the various components of the system such as, for example, the octocoupler, the integrated load management circuit for the battery, the relay, etc. And now, too, with the communication ports located on the circuit board or printed circuit (PCB).

Finally, the system is completed with the luminous sector, composed of the different LEDs that emit light and are managed / controlled by means of the mosfet that is subordinated to the microcontroller of the one who receives the orders to amplify or change the lighting until reaching the desired one, in which repertoire will be to scale the intensity, fix it in intermittence, etc., all this facilitated by a button to the effect that, depending on the different pulse intervals to which it is subjected, will establish the function that previously has been memorized in the program .

In a second realization, starting from the circuit board or printed circuit (PCB), as described, we can incorporate in any of its communication ports more advanced electronic elements that allow to significantly increase the performance of the device.

The most prominent incorporation will be a PLC that allows a programming of response functions to other elements equally connected to the other communication ports, such as sensors from which it will receive information from abroad, translating it into an automated response to carry out events that could be of a luminous, acoustic nature, of activation of mechanisms, etc.,

All this under the appropriate connections for both the power supply and the reception / transmission of control orders and actions management.

In this second case of realization and thanks to the PLC we can split the circuit board or printed circuit (PLC), separating the portion that contains the LEDs from the portion that supports the rest of the electronic elements, the electric current wires being the ones that serve as support for the communication of these fractions, resulting in a distant operation identical to that which occurs in a single piece.

The presence of the PLC allows you to remotely program each of the luminaires indicating individual orders or in groups through the possibility of an interface or graphic window that can be recreated for screens.

The sensors that can be coupled to the communication ports cover the entire spectrum of those that exist or could be compatible in the future, so the information dimension accessible to the system can reach it from heat levels, humidity, sound of door bells or telephone etc., until saturation of smoke, presence, movement, etc.
