Description
【０００１】[0001]
この考案は、表示灯に関するものである。 This invention relates to an indicator light.
【０００２】[0002]
従来例を図３ないし図５に示す。すなわち、この表示灯はエッジライト方式で あり、一側面を入射面５０とした直方体状の導光板５１と、この導光板５１の表 面を被覆する表示板５２と、導光板５１の入射面５０と反対側の側面を被覆する 第１の透光板５３と、導光板５１の他の一対の側面を被覆する一対の第２の透光 板５４とを備え、表示板５２および第１の透光板５３を一体に形成し、第２の透 光板５４をその側面に挿着していた。 Conventional examples are shown in FIGS. That is, this indicator lamp is an edge light type, and has a rectangular parallelepiped light guide plate 51 having one side surface as an incident surface 50, a display plate 52 covering the surface of the light guide plate 51, and an incident surface 50 of the light guide plate 51. And a pair of second light transmitting plates 54 that cover the other pair of side surfaces of the light guide plate 51, and the display plate 52 and the first light transmitting plate 54. The optical plate 53 is integrally formed, and the second transparent plate 54 is attached to the side surface thereof.
【０００３】[0003]
しかし、第１の透光板５３の内側が導光板５１と密着するためにはＵ字に曲げ る前にコーナ部にＶ字の溝５５を形成する必要があり、この溝５５は肉厚が薄い ため強度的に弱く、かつ曲げるのが製造上困難であった。 またランプの光が導光板５１を通して第１の透光板５３に強く入射し、表示板 ５２には弱いため第１の透光板５３が高輝度で表示板５２が低輝度となり、この ため表示項目が見づらくなるという欠点があった。なお、第２の透光板５４から の光はランプ端部に近いため、表示板５２よりも低輝度となる。すなわち輝度は 高い順に第１の透光板５３、表示板５２、第２の透光板５４となり、表示面が最 も見やすい順すなわち表示板５２、第１の透光板５３および第２の透光板５４の 順序とは異なるものであった。 However, in order for the inside of the first transparent plate 53 to be in close contact with the light guide plate 51, it is necessary to form a V-shaped groove 55 in the corner before bending it into a U-shape, and this groove 55 has a wall thickness of Since it is thin, it is weak in strength and difficult to bend in manufacturing. Further, since the light of the lamp is strongly incident on the first light transmitting plate 53 through the light guide plate 51 and weak on the display plate 52, the first light transmitting plate 53 has a high brightness and the display plate 52 has a low brightness. There was a drawback that the items became hard to see. Since the light from the second transparent plate 54 is near the end of the lamp, it has lower brightness than the display plate 52. That is, the first translucent plate 53, the display plate 52, and the second translucent plate 54 are arranged in descending order of brightness, and the display surface is in the order in which it is most visible, that is, the display plate 52, the first translucent plate 53, and the second transmissive plate. The order of the light plates 54 was different.
【０００４】 したがって、この考案の目的は、製造が容易で強度も強くでき、しかも表示板 が最も見やすい表示灯を提供することである。Therefore, it is an object of the present invention to provide an indicator lamp which is easy to manufacture, has a high strength, and whose display plate is the most visible.

【課題を解決するための手段】 この考案の表示灯は、一側面を入射面とした直方体状の導光板と、この導光板 の表面を被覆する表示板と、前記導光板の前記入射面と反対側の側面を被覆する 第１の透光板と、前記導光板の他の一対の側面を被覆する一対の第２の透光板と を備え、前記表示板および前記第１の透光板を別体に形成するとともに、前記第 １の透光板および第２の透光板の輝度が前記表示板の輝度と同等以下となるよう に前記第１の透光板，前記第２の透光板および前記表示板の透過率を設定したこ とを特徴とするものである。Means for Solving the Problems A display lamp according to the present invention comprises a rectangular parallelepiped light guide plate having one side surface as an incident surface, a display plate covering the surface of the light guide plate, and the incident surface of the light guide plate. The display plate and the first light-transmissive plate are provided with a first light-transmissive plate that covers the opposite side surface and a pair of second light-transmissive plates that cover the other pair of side surfaces of the light guide plate. And the first transparent plate and the second transparent plate so that the brightness of the first transparent plate and the second transparent plate is equal to or less than the brightness of the display plate. It is characterized in that the transmittances of the light plate and the display plate are set.
【０００６】[0006]
この考案の構成によれば、ランプを点灯すると導光板の入射面より光が入射し 、導光板の他の表面より透過するが、第１の透光板および第２の透光板の輝度が 表示板の輝度と同等以下となるように第１の透光板，第２の透光板および表示板 の透過率を設定したため、表示板が最も見やすくなり、表示板が明るく表示板の 周囲が暗い最適の表示灯が実現できる。しかも第１の透光板を表示板と別体にし たため、製造が容易で連結強度も接着剤等により容易に確保できる。さらに第１ の透光板に代えて、透過率の大きい透明板，遮光板やビーム角を小さくする部材 などを適用できるので異なる商品への対応が容易にできる。 According to the configuration of the present invention, when the lamp is turned on, light is incident from the incident surface of the light guide plate and transmitted from the other surface of the light guide plate, but the brightness of the first light transmitting plate and the second light transmitting plate is reduced. Since the transmissivity of the first translucent plate, the second translucent plate and the display plate is set so as to be equal to or less than the brightness of the display plate, the display plate is the most visible and the display plate is bright and the surrounding area of the display plate is A dark optimal indicator light can be realized. Moreover, since the first light-transmitting plate is provided separately from the display plate, it is easy to manufacture and the connecting strength can be easily secured by an adhesive or the like. Further, instead of the first light-transmitting plate, a transparent plate having a high transmittance, a light-shielding plate, a member for reducing the beam angle, etc. can be applied, so that different products can be easily handled.

この考案の一実施例を図１および図２により説明する。すなわち、この表示灯 は、導光板１と、表示板２と、第１の透光板３と、第２の透光板４と、器具本体 ５とを有する。 まず、器具本体５は、導光板１の入射面７側を保持するもので、ランプソケッ ト（図示せず）およびランプソケットに装着されて入射面７に対面するランプ（ 図示せず）を有している。 An embodiment of this invention will be described with reference to FIGS. That is, this indicator lamp has a light guide plate 1, a display plate 2, a first light transmitting plate 3, a second light transmitting plate 4, and a device body 5. First, the fixture body 5 holds the incident surface 7 side of the light guide plate 1, and has a lamp socket (not shown) and a lamp (not shown) mounted on the lamp socket and facing the incident surface 7. ing.
【０００８】 導光板１は、一側面を入射面７とした直方体状をなしている。８は取付孔であ る。 表示板２は、導光板１の表面を被覆するもので、実施例では導光板１の表裏に 設けられる。９は取付孔８に整合する連結孔である。 第１の透光板３は、導光板１の入射面７と反対側の側面１０を被覆するが、内 面に一対の突条１１を形成し、突条１１の側面と第１の透光板３の内面が表示板 ２の下端縁に接触し接着剤等により接合固定される。この第１の透光板３は押出 成形により形成される。The light guide plate 1 is in the shape of a rectangular parallelepiped whose one side surface is an incident surface 7. 8 is a mounting hole. The display plate 2 covers the surface of the light guide plate 1, and is provided on the front and back of the light guide plate 1 in the embodiment. Reference numeral 9 is a connecting hole aligned with the mounting hole 8. The first light-transmissive plate 3 covers the side surface 10 of the light guide plate 1 on the side opposite to the incident surface 7, but has a pair of ridges 11 formed on the inner surface thereof. The inner surface of the plate 3 comes into contact with the lower edge of the display plate 2 and is joined and fixed with an adhesive or the like. The first transparent plate 3 is formed by extrusion molding.
【０００９】 一対の第２の透光板４は、導光板１の他の一対の側面１２を被覆するが、内面 に突条１３を形成し、突条１３と表示板２の側縁とを接触して接着剤等により接 合している。またこの第１の透光板４は第１の透光板３と同様に押出成形により 形成される。 この場合、第１の透光板３および第２の透光板４の輝度を表示板２の輝度と同 等以下としており、そのため第１の透光板２および第２の透光板４は、表示板１ の透過率よりも透過率の小さい材質を用いている。また入射光が強い第１の透光 板３の透過率を第２の透光板４の透過率より低い材質にして、両者の輝度が同じ 程度となるようにしている。また表示板２，第１の透光板３および第２の透光板 ４により箱を形成しておき、この箱内に導光板１を挿入し、連結孔９および取付 孔８を通して器具本体５に取付け、導光板１の入射面７にランプが対面するよう にしている。The pair of second translucent plates 4 covers the other pair of side faces 12 of the light guide plate 1, but has a ridge 13 formed on the inner surface thereof so that the ridge 13 and the side edge of the display plate 2 are connected to each other. They are in contact with each other and are bonded with adhesive. The first transparent plate 4 is formed by extrusion molding like the first transparent plate 3. In this case, the brightness of the first translucent plate 3 and the second translucent plate 4 is set to be equal to or less than the brightness of the display plate 2, so that the first translucent plate 2 and the second translucent plate 4 are A material having a smaller transmittance than that of the display panel 1 is used. Further, the transmittance of the first transparent plate 3 having a strong incident light is made lower than that of the second transparent plate 4 so that the brightness of the both is about the same. Further, a box is formed by the display plate 2, the first translucent plate 3 and the second translucent plate 4, the light guide plate 1 is inserted into the box, and the instrument body 5 is inserted through the connecting hole 9 and the mounting hole 8. The lamp faces the entrance surface 7 of the light guide plate 1.
【００１０】 この実施例によれば、ランプを点灯すると導光板１の入射面７より光が入射し 、導光板１の他の表面より透過するが、第１の透光板３および第２の透光板４の 輝度が表示板２の輝度と同等以下となるように第１の透光板，第２の透光板およ び表示板の透過率を設定したため、表示板２が最も見やすくなり、表示板２が明 るく表示板２の周囲が暗い最適の表示灯が実現できる。しかも第１の透光板３を 表示板２と別体にしたため、製造が容易で連結強度も接着剤等により容易に確保 できる。さらに第１の透光板３に代えて、透過率の大きい透明板，遮光板やビー ム角を小さくする部材などを適用できるので異なる商品への対応が容易にできる 。According to this embodiment, when the lamp is turned on, light is incident from the incident surface 7 of the light guide plate 1 and is transmitted from the other surface of the light guide plate 1, but the first light transmitting plate 3 and the second light transmitting plate 3 are used. Since the transmittances of the first transparent plate, the second transparent plate, and the display plate are set so that the brightness of the transparent plate 4 is equal to or less than the brightness of the display plate 2, the display plate 2 is the most visible. Therefore, it is possible to realize an optimum indicator lamp in which the display plate 2 is bright and the periphery of the display plate 2 is dark. Moreover, since the first light-transmitting plate 3 is provided separately from the display plate 2, it is easy to manufacture and the connecting strength can be easily secured by an adhesive or the like. Further, instead of the first light-transmitting plate 3, a transparent plate having a high transmittance, a light-shielding plate, a member for reducing the beam angle, etc. can be applied, so that different products can be easily dealt with.
【００１１】 なお、前記表示板２は２面とも透光性を有したが、片面のみ透光性を有しても よい。また表示板２と第１の透光板３および第２の透光板４とは前記した接着剤 に限らず、他の連結手段により連結可能である。Although the display panel 2 has a light-transmitting property on both surfaces, only one surface may have a light-transmitting property. Further, the display plate 2, the first light-transmitting plate 3 and the second light-transmitting plate 4 can be connected not only by the above-mentioned adhesive but also by other connecting means.
【００１２】[0012]
この考案の表示灯によれば、第１の透光板および第２の透光板の輝度が表示板 の輝度と同等以下となるように第１の透光板，第２の透光板および表示板の透過 率を設定したため、表示板が最も見やすくなり、表示板が明るく表示板の周囲が 暗い最適の表示灯が実現できる。しかも第１の透光板を表示板と別体にしたため 、製造が容易で連結強度も接着剤等により容易に確保できる。さらに第１の透光 板に代えて、透過率の大きい透明板，遮光板やビーム角を小さくする部材などを 適用できるので異なる商品への対応が容易にできるという効果がある。 According to the indicator lamp of the present invention, the first light transmitting plate, the second light transmitting plate and the second light transmitting plate are controlled so that the brightness of the first light transmitting plate and the second light transmitting plate is equal to or less than the brightness of the display plate. Since the transmittance of the display board is set, the display board is most visible, and the optimum display lamp with a bright display board and a dark surrounding area can be realized. Moreover, since the first translucent plate is separate from the display plate, it is easy to manufacture and the connecting strength can be easily secured by an adhesive or the like. Further, instead of the first light-transmitting plate, a transparent plate having a high transmittance, a light-shielding plate, a member for reducing the beam angle, or the like can be applied, so that it is possible to easily deal with different products.
