Tehnički problem Technical problem
Svjetlosni displeji pomoću kojih se vrši prikazivanje reklamnih ili drugih poruka s vidljivih površina displeja okrenutih motriteljima, osvijetljenih električnim ili drugim izvorima svjetla postavljenim iza vidljive površine displeja, sastoje se uglavnom od krutih kućišta i izvora svjetlosti. Izvedbe kućišta i električnih izvora svjetlosti moraju zadovoljavati propise o sigurnosti uporabe displeja. Zbog toga su kućišta najčešće načinjena od metala ili kombinacija metalnih konstrukcija, drveta i polimernih materijala a izvori svjetlosti su najčešće električni izvori. Posebna pozornost pri izradi ovih displeja mora biti posvećena električnim i toplinskim svojstvima materijala od kojih su displeji građeni. Pouzdanost displeja postiže se uporabom nezapaljivih materijala i materijala s visokim elektroizolacionim svojstvima što ih kao proizvode poskupljuje. Light displays, which are used to display advertising or other messages from the visible surfaces of the display facing the viewers, illuminated by electric or other light sources placed behind the visible surface of the display, consist mainly of rigid housings and light sources. The designs of the housing and electric light sources must comply with the regulations on the safety of use of displays. For this reason, the housings are usually made of metal or a combination of metal constructions, wood and polymer materials, and the light sources are usually electric sources. When making these displays, special attention must be paid to the electrical and thermal properties of the materials from which the displays are made. The reliability of the display is achieved by using non-flammable materials and materials with high electrical insulating properties, which makes them more expensive as products.
Izumom se rješava tehnički problem izrade pouzdanih, funkcionalnih i ekonomičnih displeja sa električnim izvorima svjetlosti u kućištima od lako zapaljivih materijala kao što su karton ili nesamogasive vrste polimernih materijala. The invention solves the technical problem of making reliable, functional and economical displays with electric light sources in housings made of easily flammable materials such as cardboard or non-self-extinguishing types of polymer materials.
Stanje tehnike State of the art
U primjeni postoje različite izvedbe reklamnih svjetlosnih displeja čija je radna pouzdanost utemeljena na upotrebi materijala za kućišta i električne komponente visokih termoizolacionih i elektroizolacionih svojstava. In use, there are different versions of advertising light displays whose operational reliability is based on the use of materials for housings and electrical components with high thermal and electrical insulation properties.
U patentu GB2128009 opisan je svjetlosni displej čije je kućište izrađeno iz plastičnog materijala i koje je iznutra obloženo reflektirajućom aluminijskom folijom. Električni izvor svjetlosti je jedna žarulja direktno priključena na kućnu električnu mrežu. Patent GB2128009 describes a light display whose housing is made of plastic material and which is internally lined with reflective aluminum foil. The electrical light source is a light bulb directly connected to the home electrical network.
U patentu US6042243 opisano je modularno kućište svjetlosnog displeja izrađeno iz polimernih krutih okvira i ploča. Patent US6042243 describes a modular light display housing made of polymer rigid frames and panels.
U patentu US3824723 opisana je električna shema upravljanja i regulacije rada složenog svjetlosnog displeja koji se sastoji više odvojenih pojedinačnih displeja. Patent US3824723 describes the electrical scheme of the control and regulation of the operation of a complex light display consisting of several separate individual displays.
U patentu GB2128313 opisana je noćna svjetiljka za projiciranje slikovnih poruka u dječjim sobama koja se sastoji od krutog kućišta s izmjenjivim displejom u kojem je smještena jedna ili više električnih sijalica koje se napajaju električnom strujom niskog napona iz transformatora priključenog na kućnu električnu mrežu. Patent GB2128313 describes a night lamp for projecting visual messages in children's rooms, which consists of a rigid housing with a replaceable display in which one or more electric bulbs are located, which are powered by low voltage electricity from a transformer connected to the home electrical network.
Sva navedena rješenja svjetlosnih displeja sastoje se iz relativno složenih kućišta načinjenih od krutih metalnih i/ili polimernih materijala. Napajanje izvora svjetlosti električnom energijom iz kućne električne mreže uzrokuje zagrijavanje unutrašnjih prostora kućišta. Prijelaz topline s izvora svjetlosti na kućište sprečava se različitim slojevima koji reflektiraju ili apsorbiraju toplinu. Rješenja s napajanjem izvora svjetlosti električnom energijom niskog napona iz transformatora priključenih na kućnu električnu mrežu znatno poskupljuju izvedbe displeja. Zbog toga su tržišne cijene opisanih rješenja relativno visoke a primjena strogo namjenska. All the listed light display solutions consist of relatively complex housings made of rigid metal and/or polymer materials. Powering the light source with electricity from the home electrical network causes heating of the interior spaces of the housing. The transfer of heat from the light source to the housing is prevented by various layers that reflect or absorb heat. Solutions with powering the light source with low-voltage electricity from transformers connected to the home electrical network significantly increase the cost of display performance. Because of this, the market prices of the described solutions are relatively high, and the application is strictly dedicated.
Bit izuma The essence of invention
Reklamni svjetlosni displej prema izumu je uređaj koji se sastoji od kućišta, u cijelosti načinjenog od kartona ili drugih lakozapaljivih materijala i električnog svjetlosnog uređaja koji se napaja električnom energijom iz kućne električne mreže. The advertising light display according to the invention is a device that consists of a housing, entirely made of cardboard or other easily flammable materials, and an electric light device that is powered by electricity from the home electrical network.
Električni svjetlosni uređaj je niskoenergetski uređaj smješten u cijelosti u kućištu displeja. Napaja se izmjeničnim strujom napona 220 V frekvencije 50 Hz koja se poluvodičkim uređajem pretvara u istosmjernu struju niske snage kojom se napajaju električni izvori svjetlosti male snage. Ukupna toplina proizvedena radom električnih izvora svjetlosti podiže temperaturu zraka u kućištu na najvišu temperaturu koja je ispod iznosa polovice temperature samozapaljivosti materijala od kojeg je načinjeno kućište. Prijelaz topline s nosača električnih izvora svjetlosti na kućište sprečava se slojem termoizolacionog materijala umetnutim između nosača električnih izvora svjetlosti i kućišta. Ukupna toplina proizvedena radom električnih izvora svjetlosti i prenesena zračenjem i dodirom s električnih izvora svjetlosti na kućište u trajnom radu ne može izazvati zapaljenje kućišta. Ovakva električna, toplinska i izolaciona svojstva električnog svjetlosnog uređaja omogućavaju primjenu lakozapaljivih materijala za izradu kućišta svjetlosnog displeja. The electric light device is a low-energy device located entirely in the display housing. It is powered by alternating current of voltage 220 V, frequency 50 Hz, which is converted by a semiconductor device into low-power direct current, which is used to power low-power electric light sources. The total heat produced by the operation of electric light sources raises the temperature of the air in the housing to the highest temperature, which is below half of the self-ignition temperature of the material from which the housing is made. The transfer of heat from the electric light source support to the housing is prevented by a layer of thermal insulation material inserted between the electric light source support and the housing. The total heat produced by the operation of electric light sources and transferred by radiation and contact from electric light sources to the housing in continuous operation cannot cause the housing to ignite. Such electrical, thermal and insulating properties of the electric light device enable the use of highly flammable materials for the manufacture of the light display housing.

Opis izvedbe Performance description
Reklamni svjetlosni displej prema izumu sastoji se od višedijelnog kućišta i električnog svjetlosnog uređaja smještenog u kućište. The advertising light display according to the invention consists of a multi-part housing and an electric light device located in the housing.
Primjer izvedbe kućišta displeja prikazan je na slikama 1 i 2. Prikazano kućište u oblikovnom smislu predstavlja jednu od poznatih, najčešćih izvedbi kućišta svjetlosnih displeja s jednom ravnom plohom za prikazivanje poruka. Ima oblik šupljeg kvadra načinjenog od neprozirnog jednoslojnog donjeg dijela 1 i višeslojnog gornjeg dijela koji se sastoji od jednog ili više slojeva 2, 3 s otvorima 4 koji zajedno tvore svjetlosnu poruku. Gornji dio kućišta presvučen je svjetlopropusnom folijom 5 koja prekriva otvore 4. Donji i gornji dio kućišta izrađeni su od kartonskih ploča ili polimernih ploča međusobno povezanih utorenim vezama i/ili lijepljenjem. An example of the design of the display case is shown in Figures 1 and 2. In terms of design, the case shown represents one of the known, most common designs of the light display case with one flat surface for displaying messages. It has the shape of a hollow cube made of an opaque single-layer lower part 1 and a multilayer upper part consisting of one or more layers 2, 3 with openings 4 which together form a light message. The upper part of the housing is covered with a light-transmitting foil 5 that covers the openings 4. The lower and upper parts of the housing are made of cardboard boards or polymer boards connected to each other by slotted connections and/or gluing.
Električni svjetlosni uređaj displeja čini sklop sastavljen od vodiča, spojnih elemenata, poluvodičkog ispravljačkog elementa, električnih rasvjetnih tijela, nosača električnog sklopa i izolacijske podloge u jedan strujni krug. Smješten je u kućište displeja tako da su rasvjetna tijela postavljena i raspoređena ispod otvora koji tvore svjetlosnu poruku. The display's electric lighting device consists of a circuit composed of conductors, connecting elements, a semiconductor rectifier element, electric lighting fixtures, an electrical circuit support and an insulating substrate in one circuit. It is placed in the housing of the display so that the lighting fixtures are placed and arranged under the openings that form the light message.
Primjer izvedbe električnog svjetlosnog uređaja prikazan je na slikama 1, 2 i 3. Uređaj se napaja izmjeničnom strujom napona 220 V frekvencije 50 Hz preko napojnog kabla 6 s utikačem 7 i s prekidačem ili bez njega. Slobodni kraj kabla 6 stezačem 8 pričvršćen je na nosač 10 električnog sklopa a izvodi kabla 6 učvršćeni su u otvorima redne dvopolne stezaljke 9 koja je također pričvršćena na nosač 10 električnog sklopa. Nosač 10 električnog sklopa je pločica od pertinaksa s tiskanim serijskim ili paralelnim strujnim krugom koji počinje na jednom priključku redne dvopolne stezaljke 9 a završava na drugom priključku redne dvopolne stezaljke 9. Dimenzije pločice s tiskanim strujnim krugom određene su dimenzijama svjetlosne poruke izvedene na gornjem dijelu kućišta displeja. U primjeru izvedbe serijskog strujnog kruga prikazanog na slici 3 na početku strujnog kruga nalazi se dioda D koja izmjeničnu struju napona 220 V i frekvencije 50 Hz pretvara u istosmjernu struju niskog napona i male snage. U serijski strujni krug spojene su žarulje Z1, Z2, ... Zn kojima se osvjetljava svjetlosna poruka. Broj i raspored žarulja određen je također dimenzijama svjetlosne poruke izvedene na gornjem dijelu kućišta displeja. Uočljivost svjetlosne poruke može biti naglašena izmjeničnim paljenjem i gašenjem svjetlosnog izvora displeja. Prekidanje i uspostavljanje strujnog toka može vršiti vremenski programiranim električnim uređajem ili žaruljom Z1 koja osim žarne niti ima bimetalni temperaturni prekidač. Nosač 10 sa svim opisanim komponentama strujnog kruga pričvršćen je vijcima na izolacijsku podlogu 11 koja je lijepljenjem pričvršćena na donji dio 1 kućišta displeja. Na taj način je nosač 10 s komponentama električnog svjetlosnog uređaja dodatno toplinski i električno izoliran od kućišta displeja. An example of the design of an electric lighting device is shown in Figures 1, 2 and 3. The device is powered by alternating current of voltage 220 V, frequency 50 Hz via power cable 6 with plug 7 and with or without a switch. The free end of the cable 6 is attached to the support 10 of the electrical circuit with a clamp 8, and the ends of the cable 6 are fixed in the openings of the regular two-pole clamp 9, which is also attached to the support 10 of the electrical circuit. The support 10 of the electrical circuit is a plate made of pertinax with a printed serial or parallel circuit that starts at one connection of the in-line two-pole terminal 9 and ends at the other connection of the in-line two-pole terminal 9. The dimensions of the plate with the printed circuit are determined by the dimensions of the light message made on the upper part of the housing display. In the example of the series circuit shown in Figure 3, at the beginning of the circuit there is a diode D that converts alternating current of voltage 220 V and frequency 50 Hz into direct current of low voltage and low power. Bulbs Z1, Z2, ... Zn are connected to the series circuit, which illuminate the light message. The number and arrangement of the bulbs is also determined by the dimensions of the light message displayed on the upper part of the display housing. The perceptibility of the light message can be emphasized by alternately turning on and off the light source of the display. Interrupting and reestablishing the current flow can be done by a time-programmed electrical device or a Z1 bulb that, in addition to the filament, has a bimetallic temperature switch. The support 10 with all the described components of the circuit is attached with screws to the insulating base 11 which is attached to the lower part 1 of the display case by gluing. In this way, the support 10 with the components of the electric light device is additionally thermally and electrically isolated from the display housing.
