Description
【０００１】[0001]
本考案は、照光装置に係り、特にリモートコントロール装置等の文字板等を照 光するための照光装置に関する。 The present invention relates to an illuminating device, and more particularly to an illuminating device for illuminating a dial such as a remote control device.
【０００２】[0002]
従来のリモートコントロール装置に使用されている文字盤等の照光装置として は、例えばリモートコントロール装置の照明すべき各文字列毎に、ＬＥＤ等の光 源を複数個配設して照光するものや、１個のＬＥＤの光を照光用導光体で複数に 分光して複数の照明すべき各文字列を照光するものがあった。特に後者のタイプ としては、実開平２ー４７６０２号公報に開示されているものがある。この実用 新案公開公報に開示されている照光装置は、図６に示すように照光用導光体１０ の一端に配置されたＬＥＤ１１の光は、複数の照光部１２、１２・・・に分光さ れ、白印印刷等の加工がされた照光部１２の底面で、照光部１２上の表示体とし ての透明シート１３に配置された各文字１４の方向へ拡散反射されることにより 、各文字１４を照光する様になっている。 Illumination devices such as a dial used in a conventional remote control device include, for example, a plurality of light sources such as LEDs arranged to illuminate each character string to be illuminated by the remote control device. There has been one that splits the light of one LED into a plurality of light by an illumination light guide and illuminates a plurality of character strings to be illuminated. Particularly, the latter type is disclosed in Japanese Utility Model Laid-Open No. 2-47602. In the illumination device disclosed in this utility model publication, the light of the LED 11 arranged at one end of the illumination light guide 10 is split into a plurality of illumination parts 12, 12, ... As shown in FIG. Each character is diffused and reflected in the direction of each character 14 arranged on the transparent sheet 13 as a display on the illuminating part 12 on the bottom surface of the illuminating part 12 which has been subjected to a process such as white stamp printing. It is supposed to illuminate 14.
【０００３】 またさらに、照光部の両端部まで明るく照光するためにＬＥＤを２個用いた前 記考案の改良型の照光装置１５も考案されている。この照光装置１５は、図７に 示すように、第１、第２導光部１６ａ、１６ｂにより照光部１７、１７、１７に 導かれたＬＥＤ１８ａ、１８ｂの光が、照光部１７、１７、１７の底面で透明シ ート１９上の各文字２０の方へ反射されて、各文字群２０が照光される構成とな っている。Furthermore, an improved illumination device 15 of the above-mentioned invention, which uses two LEDs to brightly illuminate both ends of the illumination part, has also been devised. In this illumination device 15, as shown in FIG. 7, the lights of the LEDs 18a and 18b guided to the illumination units 17, 17 and 17 by the first and second light guiding units 16a and 16b are illuminated by the illumination units 17, 17 and 17, respectively. At the bottom of the sheet, each character group 20 is reflected by being reflected toward each character 20 on the transparent sheet 19.
【０００４】[0004]
ところで、この照光装置１５には、２つのＬＥＤ１８ａ、１８ｂが使用されて いる。この２つのＬＥＤ１８ａ、１８ｂが全く同じ性能で有れば問題はないが、 実際には同じ規格のＬＥＤであったとしても、個々のＬＥＤには若干の性能のバ ラツキがある。そして性能にバラツキのあるＬＥＤを用いた場合、この２つのＬ ＥＤ１８ａ、１８ｂに同じ電流を流しても、各々の明るさに当然若干の差が発生 することとなる。この為、本来２つのＬＥＤ１８ａ、１８ｂの光が合わさること により、照光部１７の中央部が最も明るく照光されるべきところ、その最も明る い位置が照光部１７の中央部から左右どちらかにズレることになる。例えば、「 ＰＬＡＹ」という文字群２０の「Ｌ」と「Ａ」の間が照光部１７の中央に位置し 、「Ｐ」側のＬＥＤ１８ａの光が「Ｙ」側のＬＥＤ１８ｂの光よりも明るい場合 、「ＰＬＡＹ」という文字群２０の「Ａ」ないし「Ｙ」側が最も明るく光り、「 Ｐ」ないし「Ｌ」側が若干暗く光ることとなる。この様な文字群２０の光り方は 、見栄えが非常に悪く、製品の価値を著しく損なうこととなっていた。 By the way, the illumination device 15 uses two LEDs 18a and 18b. There is no problem if the two LEDs 18a and 18b have exactly the same performance, but even if the LEDs are of the same standard in practice, the individual LEDs have some performance variations. When LEDs with different performances are used, even if the same current is applied to the two LEDs 18a and 18b, a slight difference in brightness will naturally occur. Therefore, when the lights of the two LEDs 18a and 18b are originally combined, the central part of the illuminating part 17 should be illuminated most brightly, and the brightest position is shifted from the central part of the illuminating part 17 to the left or right. become. For example, when the space between “L” and “A” of the character group 20 “PLAY” is located in the center of the illumination unit 17, and the light of the “P” side LED 18a is brighter than the “Y” side LED 18b. , "PLAY", the "A" to "Y" sides of the character group 20 are brightest, and the "P" to "L" sides are slightly dark. Such a way of shining the character group 20 is very unattractive and significantly impairs the value of the product.
【０００５】 本考案は、この様な従来技術の問題点に鑑みてなされたものであり、その目的 は、複数の光源により一列状態の複数の表示部を照光する照光装置において、各 々の表示部内の明るさを均一にさせ得る照光装置を提供することを目的とする。The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a display device for illuminating a plurality of display units in a row with a plurality of light sources. It is an object of the present invention to provide an illuminating device that can make the brightness in a unit uniform.
【０００６】[0006]
上記目的を達成するために、本考案は、２つ以上の表示部を一列状に配置して 表示列を形成した表示体と、該表示体の背後に配設されて前記表示列に沿って延 びる照光部と、光源からの光を前記照光部の両端からそれぞれ照光部内に導く第 １、第２導光部と、前記照光部に形成され、第１、第２導光部からの光をそれぞ れ表示体に向けて反射する第１、第２反射面とを有し、前記表示列内の１つの表 示部を前記照光部のほぼ中央部に配置した照光装置において、前記照光部の第１ 、第２反射面の境界部の位置を前記表示列内の２つの表示部の間に対応するよう に形成したことを特徴とするものである。 In order to achieve the above object, the present invention provides a display body in which two or more display units are arranged in a row to form a display row, and a display body disposed behind the display body along the display row.

【０００７】[0007]
前記手段により、第１導光部より導かれた光を第１反射部に形成された第１反 射面により第１表示部へ、第２導光部より導かれた光を第２反射部に形成された 第２反射面により第２表示部へとそれぞれ導くことにより、各表示部をどちらか 一方の導光部からの光のみで照光することができ、各々の一つの表示部内の明る さを均一にすることができる。 By the means, the light guided from the first light guide section is directed to the first display section by the first reflecting surface formed on the first reflecting section, and the light guided from the second light guide section is directed to the second reflecting section. By guiding each of the display sections to the second display section by the second reflecting surface formed on the display section, it is possible to illuminate each display section only with the light from one of the light guide sections.

It is a principal part expanded side view which shows the 1st reflection part of this illuminating device.
【０００９】 本考案の照光装置にかかる一実施例においては、図１、図２に示すように、ア クリル樹脂等の透明な材質により形成された導光体１を有している。この導光体 １には、複数のアーチ状の照光部２、２、２が隙間を置いて略等間隔に並設され ており、これらの照光部２の両端には第１導光部３ａ、第２導光部３ｂが照光部 ２の長手方向と略直角に配置形成されている。この第１、第２導光部３ａ、３ｂ それぞれの端部には、入光部４ａ、４ｂが光源となるＬＥＤ５ａ、５ｂを覆うよ うに形成されている。そして図３に示すように、ＬＥＤ５ａ、５ｂから出た光は 、第１、第２導光部３ａ、３ｂ側に直進するとともに、その一部は入光部４ａ、 ４ｂの上面４ａ１で反射されて、第１、第２導光部３ａ、３ｂ側にそれぞれ導か れる。In one embodiment of the illumination device of the present invention, as shown in FIGS. 1 and 2, the light guide 1 is made of a transparent material such as acrylic resin. In this light guide body 1, a plurality of arch-shaped illuminating parts 2, 2 and 2 are arranged side by side at substantially equal intervals with a gap, and at both ends of these illuminating parts 2, a first light guide part 3a is formed. The second light guide section 3b is arranged and formed substantially at right angles to the longitudinal direction of the illumination section 2. At the respective end portions of the first and second light guide portions 3a and 3b, light incident portions 4a and 4b are formed so as to cover the LEDs 5a and 5b serving as light sources. Then, as shown in FIG. 3, the light emitted from the LEDs 5a and 5b goes straight to the first and second light guide portions 3a and 3b, and part of the light is reflected by the upper surfaces 4a1 of the light incident portions 4a and 4b. Are guided to the first and second light guide portions 3a and 3b, respectively.
【００１０】 また、前記照光部２と第１、第２導光部３ａ、３ｂとの連結部には、第１分光 部６、６・・・がそれぞれ複数形成されており、さらに照光部２の第１分光部６ 、６・・・とは反対側には、第２分光部７、７・・・が形成されており、この第 １分光部６と第２分光部７でＬＥＤ５ａ、５ｂの光が反射されて、第１、第２導 光部３ａ，３ｂから照光部２内にＬＥＤ５ａ、５ｂの光が導かれる。A plurality of first light splitting units 6, 6 ... Are formed at the connecting portions between the illuminating unit 2 and the first and second light guiding units 3a and 3b, respectively. Are formed on the side opposite to the first spectroscopic sections 6 1, 6 ... Of the second spectroscopic sections 6, 7 ,. Is reflected, and the light of the LEDs 5a, 5b is guided into the illumination unit 2 from the first and second light guiding units 3a, 3b.
【００１１】 また前記照光部２には、「ＰＬＡＹ」、「ＳＴＯＰ」といった光透過性の樹脂 等からなる文字群を配置した複数の第１表示部８ａと、「ＲＥＣ」という光透過 性の文字群を配置した第２表示部８ｂとが照光部２の照光面２ａ側に配置された 表示体としての光透過性のシート９上に照光部２に沿って一列状に配置されて１ つの表示列を構成している。そして通常は、シート９の第１、第２表示部８ａ、 ８ｂ以外の部分は、リモコンのケース等の遮光性の部材により遮光される。また この複数の第１表示部８ａは、照光面２ａの中央部を越える範囲まで配置されて おり、第２表示部８ａは、照光面２ａ上の第１表示部８ａのとなりに配置されて いる。さらに、照光面２ａとは反対側で第１、第２表示部８ａ、８ｂそれぞれに 対応する位置には、導光部３ａ、３ｂから照光部２に導かれた光を照光部２の照 光面２ａ側へ反射する第１反射部２ｂ、及び第２反射部２ｃがそれぞれ形成され ている。Further, the illumination unit 2 has a plurality of first display portions 8a in which a group of characters made of a light-transmitting resin such as “PLAY” and “STOP” is arranged, and a light-transmitting character “REC”. The second display section 8b in which the groups are arranged is arranged on the light-transmitting sheet 9 as a display body arranged on the side of the illuminating surface 2a of the illuminating section 2 and arranged in a line along the illuminating section 2 to form one display. Make up the columns. Then, normally, the portion of the sheet 9 other than the first and second display portions 8a and 8b is shielded by a light shielding member such as a case of a remote controller. The plurality of first display portions 8a are arranged up to a range beyond the central portion of the illumination surface 2a, and the second display portion 8a is arranged next to the first display portion 8a on the illumination surface 2a. . Further, the light guided from the light guide sections 3a and 3b to the illumination section 2 is illuminated on the illumination section 2 at positions corresponding to the first and second display sections 8a and 8b on the side opposite to the illumination surface 2a. The 1st reflective part 2b and the 2nd reflective part 2c which reflect to the surface 2a side are each formed.
【００１２】 ここでこの第１反射部２ｂ及び第２反射部２ｃをさらに詳細に説明する。図４ で示すようにまず第１反射部２ｂは、表面がピッチ約０．５ミリのノコギリ刃状 で、照光部２の中心を越える位置まで形成されており、さらにそのノコギリ刃状 の斜面である第１反射面２ｂ１、２ｂ１・・・は、第１導光部３ａから導かれる 光の進行方向に対し約４５度の角度で傾斜しており、ノコギリ刃状のもう一方の 面２ｂ２は、第２導光部３ｂから導かれる光の進行方向に対しほぼ直角となって いる。さらに第１反射部２ｂは、第１導光部３ａ付近で約３度、照光部２の中心 付近では約８度の角度で照光面２ａ側に接近している。この形状は、照光部２内 の照光面２ａと第１反射面２ｂ１、・・・との距離を短くすることにより、照光 部２の中心付近と光源から最も遠い為に弱まった光源からの光でも、充分照光部 ２の中央部を照光できる。また第２反射部２ｃは、第１反射部２ｂと逆の構成を 有し、第２反射部２ｃのノコギリ刃状の第２反射面２ｃ１、２ｃ１・・・は、第 １反射面２ｂ１、２ｂ１・・・とは逆に傾斜し、また第２反射部２ｃは、第２導 光部３ｂ付近で約３度、照光部２の中心付近では約８度の角度で照光面２ａ側に 接近している。この為第１反射部２ｂと第２反射部２ｃとの境界部には、段部２ ｄが形成されることとなる。Here, the first reflecting portion 2b and the second reflecting portion 2c will be described in more detail. As shown in FIG. 4, the first reflecting portion 2b has a saw blade shape with a pitch of about 0.5 mm and is formed up to a position beyond the center of the illuminating portion 2, and further has a saw blade slope. The first reflecting surfaces 2b1, 2b1, ... Are inclined at an angle of about 45 degrees with respect to the traveling direction of the light guided from the first light guide section 3a, and the other sawtooth-shaped surface 2b2 is It is substantially perpendicular to the traveling direction of the light guided from the second light guide portion 3b. Further, the first reflecting portion 2b approaches the illuminating surface 2a side at an angle of about 3 degrees near the first light guiding section 3a and at about 8 degrees near the center of the illuminating section 2. This shape reduces the distance between the illuminating surface 2a in the illuminating section 2 and the first reflecting surface 2b1, ..., so that the light from the light source weakened because it is far from the center of the illuminating section 2 and the light source. However, the central portion of the illumination unit 2 can be illuminated sufficiently. Further, the second reflecting portion 2c has a configuration opposite to that of the first reflecting portion 2b, and the sawtooth-shaped second reflecting surfaces 2c1, 2c1 ... Of the second reflecting portion 2c are the first reflecting surfaces 2b1, 2b1. ... and the second reflecting portion 2c approaches the illuminating surface 2a side at an angle of about 3 degrees near the second light guiding section 3b and about 8 degrees near the center of the illuminating section 2. ing. Therefore, the step portion 2d is formed at the boundary between the first reflecting portion 2b and the second reflecting portion 2c.
【００１３】 以下に、この照光装置の照光動作について説明する。まず２つのＬＥＤ５ａ、 ５ｂに電流が流れて、ＬＥＤ５ａ、５ｂが発光する。このＬＥＤ５ａ、５ｂの光 は、入光部４ａ、４ｂから第１、第２導光部３ａ、３ｂを通り、第１、第２導光 部３ａ、３ｂに設けられた第１分光部６、６、６・・・、および第２分光部７、 ７、７・・・によって、照光部２、２、２にそれぞれ導かれる。照光部２、２、 ２に導かれた光は、その光の進行方向と約４５度の角度を成す第１反射部２ｂ、 ２ｂ、２ｂの第１反射面２ｂ１、２ｂ１・・・によって、照光面２ａ、２ａ、２ ａ側に反射されることとなるが、第２導光部３ｂから照光部２に導かれた光は、 第１反射部２ｂの面２ｂ２、２ｂ２・・・が第２導光部３ｂからの光の進行方向 に対しほぼ直角になっているため、第１表示部８ａ側へは反射されることはない 。逆に、第２導光部３ｂから照光部２に導かれた光は、第２反射部２ｃの第２反 射面２ｃ１、２ｃ１・・・により第２表示部８ｂ側へ反射されるが、第１導光部 ３ａから導かれた光は、第２表示部８ｂ側へは反射されない。Illumination operation of the illumination device will be described below. First, a current flows through the two LEDs 5a and 5b, and the LEDs 5a and 5b emit light. The light of the LEDs 5a and 5b passes from the light incident portions 4a and 4b to the first and second light guiding portions 3a and 3b, and the first spectroscopic portion 6 provided in the first and second light guiding portions 3a and 3b. , And the second spectroscopic unit 7, 7, 7 ... The light guided to the illumination units 2, 2, 2 is illuminated by the first reflection surfaces 2b1, 2b1 ... Of the first reflection units 2b, 2b, 2b forming an angle of about 45 degrees with the traveling direction of the light. Although the light is reflected toward the surfaces 2a, 2a, 2a, the light guided from the second light guide portion 3b to the illuminating portion 2 is reflected by the surfaces 2b2, 2b2 ... Of the first reflecting portion 2b. Since it is substantially perpendicular to the traveling direction of the light from the light guide portion 3b, it is not reflected to the first display portion 8a side. On the contrary, the light guided from the second light guide section 3b to the illumination section 2 is reflected toward the second display section 8b by the second reflection surfaces 2c1, 2c1 ... Of the second reflection section 2c. The light guided from the first light guide portion 3a is not reflected to the second display portion 8b side.
【００１４】 また、上記の照光部２には、第１反射部２ａと第２反射部２ｂとの間に段部２ ｄが設けられているので、第１導光部３ａから導かれた光は、その大部分が第２ 反射部２ｃの上を通過し、第２導光部３ｂから導かれた光は段部２ｄにより第１ 反射部２ｂへの侵入を妨げられる。この為、第１導光部３ａの光は第２反射部２ ｃでは、第２表示部８ｂへは反射されず、第２導光部３ｂからの光は第１反射部 ２ｂで第１表示部８ａへは反射されることはない。Further, since the illuminating section 2 is provided with the step section 2 d between the first reflecting section 2 a and the second reflecting section 2 b, the light guided from the first light guiding section 3 a. Most of the light passes over the second reflecting portion 2c, and the light guided from the second light guiding portion 3b is prevented from entering the first reflecting portion 2b by the step portion 2d. Therefore, the light of the first light guide portion 3a is not reflected by the second reflection portion 2c to the second display portion 8b, and the light from the second light guide portion 3b is first displayed by the first reflection portion 2b. It is not reflected to the portion 8a.
【００１５】 なお、本考案においては、光源であるＬＥＤは必ずしも２つである必要はなく 、図５に示すように、１つのＬＥＤ５ｃを２つの入光部４ｃ、４ｄで共用するこ とにより、別々の導光部３ｃ、３ｄに光を導く構成であってもよく、また各導光 部３ｃ、３ｄに対して複数個のＬＥＤを光源として用いてもよい。さらに光の導 光経路上例えば第１、第２導光部３ａ、３ｂにＬＥＤを配置しても良い。さらに 、表示列内の各表示部は文字群に限られず、単一の文字、記号等であっても良い 。In the present invention, the number of LEDs serving as a light source is not necessarily two, and as shown in FIG. 5, one LED 5c is shared by the two light entrance portions 4c and 4d. A configuration may be adopted in which light is guided to separate light guides 3c and 3d, and a plurality of LEDs may be used as light sources for each light guide 3c and 3d. Furthermore, LEDs may be arranged on the light guide path, for example, in the first and second light guide portions 3a and 3b. Furthermore, each display part in the display row is not limited to a character group, and may be a single character, a symbol, or the like.
【００１６】[0016]
以上説明したように、本考案によれば、１つの表示列内の各々の表示部をどち らか一方の導光部からの光のみで照光できるので、各表示部内の明るさを均一に することができる。従って、各表示部の見栄えが非常によくなり、製品としての 価値が高くなる。 As described above, according to the present invention, each display section in one display row can be illuminated only by the light from one of the light guide sections, so that the brightness in each display section can be made uniform. can do. Therefore, the appearance of each display part is greatly improved, and the value as a product is increased.
