Description
458 240 2 Uppfinningen beskrivs nedan ytterligare under hänvisning till bifogade schematiska ritning, som visar en frontvy av en lampenhet enligt en såsom exempel vald utföringsform av uppfinningen. The invention is further described below with reference to the accompanying schematic drawing, which shows a front view of a lamp unit according to an exemplary embodiment of the invention.
Den på ritningen visade, generellt med 10 betecknade lampenheten uppvisar en rektangulär frontvägg ll, som är försedd med ett stort antal i horisontella rader i densamma anordnade genomgående hål 12, i vilka ett motsvarande antal lysdioder 13 är monterade i fràn nämnda hål partiellt ut- skjutande lägen.The lamp unit shown in the drawing, generally denoted by 10, has a rectangular front wall 11, which is provided with a large number of through-holes 12 arranged in horizontal rows in it, in which a corresponding number of LEDs 13 are mounted in said holes partially projecting from said holes. modes.
Lampenheten 10, som visats ytterst schematiskt på rit- ningen, kan i praktiken lämpligen vara utförd på i svenska utläggningsskriften 443 636 beskrivet och visat sätt.The lamp unit 10, which is shown extremely diagrammatically in the drawing, may in practice suitably be designed in the manner described and shown in Swedish Offenlegungsschrift 443 636.
Såsom framgår av ritningen är de på kort avstånd från varandra placerade dioderna 13, vilka samtliga är inrättade att utsända ljus av inbördes närmelsevis lika färg, delade utmed frontväggen ll, så för- att de tillsammans kommer att bilda en åtminstone närmelsevis cirkulär ljusemitterande yta 14 hos lampenheten 10. Denna yta kan dock om så önskas ges lämplig annan form. Sålunda kan den t.ex. vara kvadratisk eller rektangulär i stället för cirkulär. I alla händelser bör den emellertid ha avsevärd utsträckning i tvâ mot varandra vinkelräta riktningar.As can be seen from the drawing, the diodes 13 placed at a short distance from each other, all of which are arranged to emit lights of mutually approximately equal color, are divided along the front wall 11, so that together they will form an at least approximately circular light-emitting surface 14 of lamp unit 10. However, this surface can be given a suitable other shape if desired. Thus, it can e.g. be square or rectangular instead of circular. In any case, however, it should have a considerable extent in two mutually perpendicular directions.
För att för en färgblind person underlätta ett särskiljande av de från lampenheten utsända ljussignalerna från andra ljussignaler med avvikande färg och en identifiering av lamp- enheten såsom varande av en viss bestämd typ är lysdioderna 13 uppdelade pà tvâ skilda uppsättningar A resp. B, vilka täcker inbördes olika delar 14A resp. l4B av den ljusemitte- rande ytan l4. Vidare har de till uppsättningen A hörande lysdioderna åtminstone cirka dubbelt så hög ljusstyrka som de till uppsättningen B hörande lysdioderna. Dessutom är de till uppsättningen A hörande lysdioderna fördelade utmed den ljusemitterande ytan 14 på sådant sätt att de tillsammans bildar en inre cirkulär del 14A av ytan l4, vilken omges av en yttre ringformig del l4B, som bildas av de till uppsätt- 458 240 ningen B hörande lysdioderna.In order to facilitate a color-blind person a distinction between the light signals emitted from the lamp unit from other light signals with a different color and an identification of the lamp unit as being of a certain specific type, the LEDs 13 are divided into two different sets A and 1, respectively. B, which cover mutually different parts 14A resp. l4B of the light emitting surface l4. Furthermore, the LEDs belonging to set A have at least about twice as high a brightness as the LEDs belonging to set B. In addition, the LEDs belonging to the set A are distributed along the light-emitting surface 14 in such a way that they together form an inner circular part 14A of the surface 14, which is surrounded by an outer annular part 14B, which is formed by the sets B 458 240 hearing the LEDs.
Det bör observeras att den av uppsättningen A täckta delen l4A av ytan 14 icke behöver utgöra en cirkulär del av denna yta. De till uppsättningen A hörande lysdioderna 13 bör dock enligt uppfinningen vara fördelade utmed ytan 14 enligt ett förutbestämt mönster för att härigenom tillsammans bilda en viss figur eller ett visst tecken t.ex. en bokstav.It should be noted that the part 14A of the surface 14 covered by the set A does not have to form a circular part of this surface. According to the invention, however, the LEDs 13 belonging to the set A should be distributed along the surface 14 according to a predetermined pattern in order to thereby together form a certain figure or a certain sign, e.g. a letter.
De till uppsättningen A hörande, ljusstarkare lysdioderna kan med fördel ha flerfaldigt högre ljusstyrka än de till uppsättningen B hörande lysdioderna. Antalet lysdioder i uppsättningen A kan, särskilt i detta fall, utan olägenhet väljas betydligt lägre än antalet lysdioder i uppsättningen B.The brighter LEDs belonging to set A can advantageously have several times higher brightness than the LEDs belonging to set B. The number of LEDs in set A can, especially in this case, be chosen without inconvenience considerably lower than the number of LEDs in set B.
Lampenheten enligt uppfinningen kan med fördel ingå i en för trafikljus eller andra signalljusanordningar avsedd armatur, som är försedd med två eller flera med varandra sammanbyggda lampenheter, vilka är anordnade att utsända ljus med inbördes olika färg, t.ex. rött, gult och grönt ljus. Härvid är det möjligt att utföra enbart en av lamp- enheterna, företrädesvis den som är avsedd att avge rött ljus, på enligt uppfinningen föreslaget sätt, medan de övriga lampenheterna utföres så, att de kommer att utsända ljus med likartad karaktär från samtliga i respektive enhet ingående lysdioder. Alternativt kan dock flera eller samtliga lamp- enheter i en armatur utföras enligt uppfinningen. I detta fall måste lampenheterna utföras på inbördes olika sätt för att man skall kunna undvika risken för en förväxling av dem med varandra.The lamp unit according to the invention can advantageously be part of a luminaire intended for traffic lights or other signal light devices, which is provided with two or more lamp units interconnected, which are arranged to emit lights of mutually different color, e.g. red, yellow and green light. In this case, it is possible to design only one of the lamp units, preferably the one intended to emit red light, in the manner proposed according to the invention, while the other lamp units are designed so that they will emit light of a similar character from all in each unit. input LEDs. Alternatively, however, several or all lamp units in a luminaire can be designed according to the invention. In this case, the lamp units must be designed in mutually different ways in order to avoid the risk of confusing them with each other.
