Description

本発明は、光源にLED(Light Emitting Diode)を用いる表示装置に関する。   The present invention relates to a display device using an LED (Light Emitting Diode) as a light source.

光源に冷陰極ランプを用いた表示装置、例えば非常口の場所を知らせる誘導灯装置は知られている。このようなものにおいては、交流商用電源を直流化する電源部とこの電源部からの直流電圧で作動する高周波点灯装置を備えており、これによって表示パネルに配設される冷陰極ランプを点灯させるようにしている(例えば特許文献1参照)。   2. Description of the Related Art Display devices using a cold cathode lamp as a light source, for example, a guide light device that informs the location of an emergency exit are known. In such a system, a power source unit for converting an AC commercial power source into a DC power source and a high-frequency lighting device that operates with a DC voltage from the power source unit are provided, thereby lighting a cold cathode lamp disposed on the display panel. (For example, refer to Patent Document 1).

特開平8−273412号公報JP-A-8-273212

冷陰極ランプは、例えば一本、AC430V、45〜60kHzの高電圧、高周波の電源を用いている。このような高電圧、高周波の電源は、基本的にアースなどに対して漏れ電流を発生し易い。さらに、冷陰極ランプは細いランプからなり、電流が6mA程度と少ないため、リークが生じると、十分な輝度が得られず暗くなる。つまり、冷陰極ランプと点灯装置(インバータ電源)とを離してこれらの間を出力線で結んだ場合、この出力線からリーク電流が流れて冷陰極ランプに流れる電流が減少し暗くなってしまう。そのため、光源に冷陰極ランプを用いた表示装置にあっては、光源と点灯装置とを離すことができず、光源と点灯装置とを共に器具本体内に収容して表示パネル側に配置する構成を採っており、表示部全体としての大型化が避けられなかった。   For example, one cold cathode lamp uses a high voltage, high frequency power source of AC430V, 45-60 kHz. Such a high voltage, high frequency power supply basically tends to generate a leakage current with respect to ground. Furthermore, since the cold cathode lamp is a thin lamp and the current is as small as about 6 mA, if a leak occurs, sufficient brightness cannot be obtained and the lamp becomes dark. That is, when the cold cathode lamp and the lighting device (inverter power supply) are separated from each other and are connected by an output line, a leakage current flows from the output line, and the current flowing to the cold cathode lamp is reduced and darkened. Therefore, in a display device using a cold cathode lamp as the light source, the light source and the lighting device cannot be separated, and the light source and the lighting device are both housed in the fixture body and arranged on the display panel side. The size of the entire display unit is unavoidable.

本発明の技術的課題は、点灯装置と光源とを離れた位置に配置できるようにして、点灯装置と光源すなわち表示パネルとの間を金属製パイプなどで延長接続できるようにして、表示部全体としての小型化を図れるようにすることにある。   The technical problem of the present invention is that the lighting device and the light source can be arranged at positions separated from each other, and the lighting device and the light source, that is, the display panel can be extended and connected by a metal pipe or the like, so that the entire display unit It is to make it possible to achieve downsizing.

本発明に係る表示装置は、商用電源を所定電圧まで降圧する点灯装置が配設された器具本体と、LED光源、このLED光源が発する光が入射される表示パネル、前記表示パネルの背面側に配置され、この表示パネルを収容して前記LED光源から発する熱を放散させる蓋状の表示板保持部材、及び前記LED光源が取り付けられる基板と一体化され、前記表示パネルを前記表示板保持部材とで挾持するように、前記表示板保持部材に着脱可能に取り付けられた放熱特性の良い材料からなるランプカバーを備え、器具本体から離して配置された表示パネルユニットと、内部に点灯装置とLED光源とを電気的に接続する電線が挿通され、かつ器具本体と表示パネルユニットとを機械的に接続するパイプと、を備えたものである。 A display device according to the present invention includes a fixture main body provided with a lighting device for stepping down a commercial power source to a predetermined voltage, an LED light source , a display panel on which light emitted from the LED light source is incident, and a back side of the display panel. And a lid-like display plate holding member that accommodates the display panel and dissipates heat generated from the LED light source, and a substrate to which the LED light source is attached, and the display panel is integrated with the display plate holding member. The display panel unit is provided with a lamp cover made of a material having a good heat dissipation characteristic, which is detachably attached to the display plate holding member so as to be held by the display panel holding member, and a lighting device and an LED light source disposed inside the display panel unit. preparative electrically wire insertion to connect, and a pipe for mechanically connecting the instrument body and a display panel unit, those having a.

本発明の表示装置によれば、光源にLEDを用い、点灯装置からLED光源に低電圧定電流を出力するため、従来のような漏れ電流の問題は無くなり、光源と点灯装置とを結ぶ電線(出力線)からリーク電流が流れることがなくなる。このため、光源と点灯装置とを結ぶ電線を長くすることができて、点灯装置と光源とを離れた位置に配置することができる。そして、点灯装置と光源との間、つまり器具本体と表示パネルユニットとの間を金属製パイプなどで延長接続することができて、設計的自由度が拡大する。さらに、表示パネルユニットを薄くできるので、表示部全体としての小型化が図れ、美観に優れたものが得られる。
また、表示パネルの背面側に、この表示パネルを収容してLED光源から発する熱を放散させる蓋状の表示板保持部材を配置するとともに、LED光源の基板を放熱特性の良い材料からなるランプカバーと一体化し、このランプカバーと表示板保持部材とで表示パネルを挾持するように、ランプカバーを表示板保持部材に着脱可能に取り付けたので、表示パネルの表示板保持部材からの脱落を確実に防止でき、かつランプ交換が容易となる。さらに、LED光源から発する熱を前面側からも放散させることができる。
According to the display device of the present invention, since an LED is used as a light source and a low voltage constant current is output from the lighting device to the LED light source, there is no problem of leakage current as in the prior art, and an electric wire connecting the light source and the lighting device ( No leakage current flows from the output line. For this reason, the electric wire which connects a light source and a lighting device can be lengthened, and a lighting device and a light source can be arrange | positioned in the position away. And it can extendly connect between a lighting device and a light source, ie, between an instrument main body and a display panel unit, with a metal pipe etc., and a design freedom expands. Furthermore, since the display panel unit can be thinned, the entire display unit can be reduced in size, and an excellent aesthetic appearance can be obtained.
In addition, a lid-like display board holding member that houses the display panel and dissipates heat emitted from the LED light source is disposed on the back side of the display panel, and the LED light source substrate is a lamp cover made of a material having good heat dissipation characteristics. Since the lamp cover is detachably attached to the display plate holding member so that the display panel is held between the lamp cover and the display plate holding member, the display panel can be securely removed from the display plate holding member. This can be prevented and the lamp can be easily replaced. Furthermore, the heat generated from the LED light source can be dissipated from the front side.

A display panel 4 having a display panel, that is, an induction display panel 3, and a display panel unit 4 arranged away from the instrument body 1 and an electric wire (not shown) electrically connecting the lighting device and the LED light source 2 are inserted therein. And a metal pipe 5 that mechanically connects the instrument body 1 and the display panel unit 4, and a short pipe 5 a that is provided on the pipe 5 and protrudes in the direction orthogonal to the axis thereof and the tip abuts against the display panel unit 4. 5b. In addition to the lighting device, the appliance main body 1 is supplied with power from the battery, a charging circuit for charging the battery, and a commercial power source at normal times, and is supplied with power from the battery at the time of a power failure or the like. A switching circuit for switching is also provided. Alternatively, a lighting device may be used in which LED light sources are connected in anti-parallel, and an AC power source in which a commercial power source is stepped down to a predetermined voltage is fed to the LED light source to turn on the LED light source.

これを更に詳述すると、LED光源2は、図5及び図6のようにLED基板6を放熱特性の良い材料(例えばアルミニウム)からなるランプカバー7と一体化して構成されている。   More specifically, the LED light source 2 is configured by integrating the LED substrate 6 with a lamp cover 7 made of a material having good heat dissipation characteristics (for example, aluminum) as shown in FIGS. 5 and 6.

また、誘導表示パネル3は、表示をするための模様(誘導表示)が描かれた前面パネル3aと、輝度を一定にさせるための加工を施され、前面パネル3aの背面に配置された導光板3bと、導光板3bの背面に配置されて輝度アップさせる光学シート3cと、これら前面パネル3a、導光板3b、及び光学シート3cを保持する樹脂製透明枠3dとから構成されている。   In addition, the guidance display panel 3 includes a front panel 3a on which a display pattern (guidance display) is drawn, and a light guide plate that is processed to make the luminance constant and is arranged on the back surface of the front panel 3a. 3b, an optical sheet 3c arranged on the back surface of the light guide plate 3b to increase brightness, and a front panel 3a, the light guide plate 3b, and a resin transparent frame 3d for holding the optical sheet 3c.

また、誘導表示パネル3の背面側には、誘導表示パネル3を収容してLED光源2から発する熱を放散させる蓋状の表示板保持部材8が設けられ、表示板保持部材8をねじ9によりパイプ5側に接続することで、器具本体1と表示パネルユニット4とを接続するようになっている。なお、図5ではパイプ5と表示板保持部材8との間に取付金具11が介在しているものを示してあるが、図1乃至図3に示すような短管5a,5bが介在する場合は、パイプ5に短管5a,5bの端部を溶接などで固定し、短管5a,5bの他方の端部に設けたフランジ部と表示板保持部材8とをねじ9にて接続するようになっている。すなわち、取付金具11や短管5a,5bは、パイプ5と表示板保持部材8との間に隙間を形成して冷却効率を上げるために設けられたものであり、必ずしも必要なものでなく、パイプ5と表示板保持部材8とを直接接続してもよい。なお、点灯装置からLED光源2までの配線は、パイプ5内から短管5a,5b内に電線を収納し、表示板保持部材8の裏面から電線を挿入して、LED光源部に接続される。また、電線にコネクタを備えて、パイプ5及び短管5a,5bを、器具本体1及び表示板保持部材8から外せるようにするとよい。また、表示板保持部材8を放熱特性のよいアルミダイキャストなどで構成して、表示板保持部材8との間に隙間を形成するとさらに冷却効率を上げることができる。   Further, on the back side of the guidance display panel 3, a lid-like display board holding member 8 that houses the guidance display panel 3 and dissipates heat emitted from the LED light source 2 is provided. By connecting to the pipe 5 side, the instrument body 1 and the display panel unit 4 are connected. FIG. 5 shows the case where the mounting bracket 11 is interposed between the pipe 5 and the display plate holding member 8, but the case where short pipes 5a and 5b as shown in FIGS. 1 to 3 are interposed. Is fixed to the pipe 5 by welding or the like, and the flange provided at the other end of the short pipes 5a and 5b and the display plate holding member 8 are connected by screws 9. It has become. That is, the mounting bracket 11 and the short pipes 5a and 5b are provided in order to form a gap between the pipe 5 and the display panel holding member 8 to increase the cooling efficiency, and are not necessarily required. The pipe 5 and the display plate holding member 8 may be directly connected. The wiring from the lighting device to the LED light source 2 is connected to the LED light source unit by housing the electric wires from the pipe 5 into the short tubes 5a and 5b and inserting the electric wires from the back surface of the display board holding member 8. . Moreover, it is good to equip an electric wire with a connector so that the pipe 5 and the short pipes 5a and 5b can be removed from the instrument main body 1 and the display board holding member 8. FIG. Further, if the display plate holding member 8 is made of aluminum die cast or the like with good heat dissipation characteristics and a gap is formed between the display plate holding member 8 and the cooling efficiency can be further increased.

またランプカバー7と表示板保持部材8とで誘導表示パネル3を挾持するように、ランプカバー7をねじ12によって表示板保持部材8に着脱可能に取り付けており、これによって誘導表示パネル3の表示板保持部材8からの脱落を確実に防止でき、かつランプ交換が容易となっている。さらに、LED光源2から発する熱を前面側からも放散させることができる。   In addition, the lamp cover 7 is detachably attached to the display plate holding member 8 with screws 12 so that the lamp display 7 and the display plate holding member 8 hold the guide display panel 3.

器具本体1は、開口を下にして天井に埋め込むように設置されており、図1及び図2のようにその底部1aには、天井のアンカーボルト13が挿通する孔1bが形成されているとともに、孔1bの周縁に、下方に突出する基本的にコ字状の台座14が取り付けられ、台座14の中央にアンカーボルト13が挿通可能な孔が形成されている。したがって、アンカーボルト13を器具本体1の孔1bから台座14の孔を貫通させ、その貫通端にナット15を取り付けることで、器具本体1をアンカーボルト13に連結することができる。その際、アンカーボルト13の台座14からの貫通部にナット15を螺合させればよいため、締結ストロークが短くて済み、かつ締結作業位置も器具本体1の中間部分に位置することとなって作業がし易い。   The instrument body 1 is installed so as to be embedded in the ceiling with the opening facing downward, and a hole 1b through which the anchor bolt 13 on the ceiling is inserted is formed in the bottom 1a as shown in FIGS. A basically U-shaped pedestal 14 protruding downward is attached to the periphery of the hole 1b, and a hole into which the anchor bolt 13 can be inserted is formed at the center of the pedestal 14. Therefore, the instrument main body 1 can be connected to the anchor bolt 13 by passing the anchor bolt 13 through the hole 1b of the instrument main body 1 from the hole 1b and attaching the nut 15 to the penetrating end. At that time, the nut 15 may be screwed into the through portion from the base 14 of the anchor bolt 13, so that the fastening stroke is short, and the fastening work position is also located in the middle part of the instrument body 1. Easy to work.

また、台座14のコ字状の両脚部には、それぞれスリット14a,14bが形成され、一方、パイプ5の基端には、これを台座14のスリット14a,14bにワンタッチで取り付けるための爪16a,16bを備えたコ字状の把持金具16が設けられている。したがって、天井に開けられた図示しない孔より器具本体1の開口内にパイプ5の基端部を差し込み(図1)、把持金具16の爪16a,16bをその弾性力によって台座14のスリット14a,14b内にそれぞれ嵌入させれば、パイプ5と器具本体1とが連結され(図2)、これらがアンカーボルト13に保持される。   In addition, slits 14a and 14b are formed in the U-shaped leg portions of the pedestal 14, respectively. On the other hand, at the base end of the pipe 5, the claws 16a for attaching the slits 14a and 14b of the pedestal 14 with one touch , 16b, and a U-shaped gripping bracket 16 is provided. Therefore, the base end portion of the pipe 5 is inserted into the opening of the instrument body 1 through a hole (not shown) opened in the ceiling (FIG. 1), and the claws 16a and 16b of the gripping metal fitting 16 are slit 14a, If each is inserted in 14b, the pipe 5 and the instrument main body 1 will be connected (FIG. 2), and these will be hold | maintained at the anchor bolt 13. FIG.

また、パイプ5には、これが貫通する天井の孔を覆うリング状の化粧パネル17を取り付けるためのクランプ部材18が設けられている。クランプ部材18は、図4のようにフランジ21aを有し内周面と外周面にそれぞれ雌ねじ21bと雄ねじ21cが形成されたダブルナット21と、ダブルナット21の雄ねじ21cに螺合する雌ねじ22aを有し、ダブルナット21のフランジ21aと協調して化粧パネル17を挟み込む化粧ナット22とから構成され、パイプ5に形成された雄ねじ5eとダブルナット21の雌ねじ21bとの螺合位置を変えることで、化粧パネル17のパイプ5への取付位置を調整できるようになっている。これにより、化粧パネル17のパイプ5への取付が容易となり、作業性が向上する。   The pipe 5 is provided with a clamp member 18 for attaching a ring-shaped decorative panel 17 that covers a hole in the ceiling through which the pipe 5 passes. As shown in FIG. 4, the clamp member 18 includes a double nut 21 having a flange 21 a and formed with an internal thread 21 b and an external thread 21 c on the inner peripheral surface and the outer peripheral surface, and an internal thread 22 a that is screwed to the external thread 21 c of the double nut 21. And includes a decorative nut 22 that sandwiches the decorative panel 17 in cooperation with the flange 21a of the double nut 21, and changes the screwing position between the male screw 5e formed on the pipe 5 and the female screw 21b of the double nut 21. The attachment position of the decorative panel 17 to the pipe 5 can be adjusted. Thereby, attachment to the pipe 5 of the decorative panel 17 becomes easy, and workability | operativity improves.

このように本実施形態においては、光源にLEDを用い、点灯装置からLED光源2に低電圧定電流を出力するため、従来のような漏れ電流の問題は無くなり、光源と点灯装置とを結ぶ電線(出力線)からリーク電流が流れることがなくなる。このため、光源と点灯装置とを結ぶ電線を長くすることができて、点灯装置と光源とを離れた位置に配置することができる。そして、点灯装置と光源との間、つまり器具本体1と表示パネルユニット4との間を金属製パイプ5などで延長接続することができて、設計的自由度が拡大する。さらに、表示パネルユニット4を薄くできるので、表示部全体としての小型化が図れ、美観に優れたものが得られる。   As described above, in this embodiment, an LED is used as the light source, and a low voltage constant current is output from the lighting device to the LED light source 2, so that there is no problem of leakage current as in the prior art, and the electric wire connecting the light source and the lighting device. No leakage current flows from the (output line). For this reason, the electric wire which connects a light source and a lighting device can be lengthened, and a lighting device and a light source can be arrange | positioned in the position away. Then, the lighting device and the light source, that is, the fixture body 1 and the display panel unit 4 can be extendedly connected by the metal pipe 5 or the like, and the degree of freedom in design is expanded. Furthermore, since the display panel unit 4 can be made thin, the display unit as a whole can be miniaturized and an excellent aesthetic appearance can be obtained.
