TITLE: STRUCTURE OF LIGHTING APPLIANCE.

DESCRIPTION

The present invention relates to a lighting apparatus structure of the type comprising a ceiling or wall support frame.

Lamps essentially constituted by a metal frame to which a support for an incandescent lamp electrically connected to the network with the interposition of a switch is associated.

This solution has the drawback linked to the need for the user to intervene on the switch to turn on the lamp and to the high energy expenditure due to the use of incandescent lamps.

Lamps are also known, called emergency lamps, which usually comprise a light source, consisting of a neon tube, powered by the mains and equipped with a sensor which, in the absence of mains power supply, gives consent for an auxiliary power supply supplied by a suitable battery.

This solution also has drawbacks, such as the fact that in any case the light source tends to quickly discharge the battery and therefore the time in which the emergency lamp remains on is very limited.

In addition, these emergency lamps usually have a parallelepiped shape that is aesthetically not very valuable and are usually placed above the crosspiece of the doors, aggravating the overall aesthetic appearance of the room in which they are placed.

Lamps are also known which use, as a light source, LEDs which must be powered at a predetermined voltage obtained by using a transformer.

Therefore, all these solutions individually have drawbacks and if the user wishes to have several functions he should necessarily use and install several different lamps jointly by placing them in different points of the room, this aggravating the costs and the aesthetic appearance of the room itself.

The main task of what is the subject of the present application is therefore to solve the technical problems highlighted, eliminating the drawbacks of the aforementioned known art and therefore devising a lighting device that has multifunctional characteristics while allowing the containment of management costs and installation times.

Within the scope of the above aim, another important object of the invention is to provide a lighting apparatus which allows it to be used to illuminate an environment both in the presence of mains power supply and in conditions of absence of mains power supply.

Another object is to provide a lighting device which can also be activated without necessarily having to use a switch.

Another object is to provide a lighting apparatus which is aesthetically valuable and which has small dimensions in relation to the functions it performs.

Not least object is to obtain an invention which is structurally simple, which has low manufacturing costs and can be produced with the usual known systems.

The aforementioned aim and objects, as well as others which will appear more clearly later, are achieved by a lighting apparatus structure, comprising a ceiling or wall support frame, which is characterized in that it consists of a power supply for one or more first LEDs with timed light or for ordinary lighting and for charging a battery for the power supply of one or more second emergency LEDs, said one or more first and second LEDs being activated by an electronic circuit enslaved by at least one sensor presence and detection of mains power supply.

Further characteristics and advantages of the invention will become clearer from the detailed description of a particular, but not exclusive, embodiment, illustrated by way of non-limiting example in the attached drawings, in which:

fig. 1 illustrates the structure in a side view;

fig. 2 illustrates the structure in a top view and without the diffuser;

fig. 3 illustrates the structure in a bottom view;

fig. 4 illustrates the structure in an axonometric view without the diffuser and with the lights on;

fig. 5 shows, in a view similar to the previous one, the emergency lights on;

fig. 6 illustrates a schematic of the electronic circuit.

In the following embodiments, single characteristics, reported in relation to specific examples, can actually be interchanged with other different characteristics, existing in other embodiments.

Furthermore, it should be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is intended not to be claimed and the subject of an excerpt (disclaimer) from the claims.

With reference to the aforementioned figures, number (1) indicates a lighting apparatus structure of the type comprising a ceiling or wall support frame, advantageously metallic and defining a container (2) for a diffuser (3), it can be removably associated with it by known means.

On the bottom (4) of the container (2) there are prearranged first holes (5) for fixing, by means of suitable screws, to the ceiling or wall and second holes (6) for the passage of the necessary cables (not shown).

At the bottom (4) of the container (2) is associated a power supply (9) for one or more first LEDs (10) with timed light and for charging a battery (12) for powering one or more second LEDs (13 ) of emergency.

This feeder (9) is advantageously placed inside an aerated, preferably cylindrical casing (14) made of plastic material, axially associated with the bottom (4).

The first timed light leds (10) are advantageously arranged in correspondence with the perimeter edge (15) of a disk (16) made integral with the bottom (4) of the container (2) and with a diameter greater than that of said casing (14) .

Once said first LEDs (10) are turned on, they generate a light which is partially reflected on the lateral surface (17) of said adjacent casing (14).

The second emergency light LEDs (13) are also arranged in correspondence with the disk (16) according to a circumference concentric to that of the laying of said first LEDs (10) and therefore are closer to the lateral surface (17) of said casing (14).

The second LEDs (13) are therefore fewer in number than said first LEDs (10) and, once turned on, their light is also partially reflected on the lateral surface (17) of said adjacent casing (14).

Said one or more first and second timed light (10) and emergency (13) LEDs can be activated by means of an electronic circuit (18) enslaved by at least a first presence sensor (19a), for example of the type known with the acronym WIBO 12001, and a second sensor (19b) for detecting the mains power supply.

As illustrated in figure 6, said electronic circuit is composed of a transformer (20) having a series of outputs at predetermined voltage values for the power supply of a microprocessor (21) (of the type known for example with the initials EP78P259NS011), for a battery (12), the first LEDs 10) and the second LEDs (13).

This transformer (20):

transforms the voltage from low to very low voltage to power said first LEDs (10), turns on and off (like a switch) said first LEDs (10) by means of a motion detector consisting of said first presence sensor (19a),

determines and regulates the lighting time of said first LEDs (10),

charges the battery (12) to power said second LEDs (13),

diverts the ignition from said first LEDs (10) to said second LEDs (13) in the event of a power failure by activating the lighting of said second LEDs (13) through the battery (12), guaranteeing the ignition of emergency for several hours as required by international safety standards,

diverts the ignition from said second LEDs (13) to said first LEDs (10) in the event of a return of electric power supply.

There are also a first actuator (23) and a second actuator (24) respectively adapted to intercept said first LEDs (10) with said microprocessor (21) and said second LEDs (13) with said microprocessor (21) and said battery (12 ).

The microprocessor (21) is connected to the sensor (19a) by means of suitable level regulators (25).

The microprocessor therefore has both the function of turning on the first and second LEDs (10,13), and of verifying the state of the battery charge (12), and of determining the lighting of the first LEDs (10) if the presence, in the room where the lamp structure (1) is inserted, of a movement.

It has thus been found that the invention has achieved the intended aim and objects, having obtained a lighting apparatus which groups in itself multiple functions such as the direct lighting of an environment, which can also be activated by the presence of the user alone, and the emergency function. all through the use of low consumption LEDs.

The lighting device thus allows it to be used to illuminate an environment both in the presence of mains power supply and in conditions of absence of mains power. The lighting device is also compact, having small dimensions in relation to the functions it performs, and therefore it does not aesthetically weigh down the room in which it is placed.

Finally, the lighting apparatus is structurally simple.

The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements.

The characteristics indicated as advantageous, convenient or the like may also be missing or be replaced by equivalents.
