【従来の技術】
従来の技術には外観が板状を呈しその両板面から光が出る面形蛍光ランプを使用した照明器具は無かった。
【０００３】
【発明が解決しようとする課題】
外観が板状を呈しその両板面から光が出る面形蛍光ランプでは、通常任意の被照射面に光を向けられるのは片方の板面から発生する光のみであり、もう一方の板面から発生する光を有効に使用する必要が有る。本発明はこれを解決する。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、外観が板状を呈しその両板面から光が出る面形蛍光ランプの片板面（甲）から発生する光の一部をもう一方の片板面（乙）に反射し、かつ片板面（甲）側にも、任意の必要な光をのこす反射板を設定する。
【０００５】
【発明の実施の形態】
図１・２を用いて本発明の実施形態について説明する。外観が板状を呈しその両板面から光が出る面形蛍光ランプ１０を備え、前記面形蛍光ランプ１０を保持する器具本体２０を備え、前記面形蛍光ランプ１０をその板面がほぼ水平となるように天井面から吊り下げ、前記面形蛍光ランプ１０の上面１１側に上向きに出る光４２を下向きの光４１に転向させる反射板３０を配置し、前記面形蛍光ランプ１０の下面１２側に下向きに出る光４０と、前記面形蛍光ランプ１０の上面１１側に上向きに出る光４２を前記反射板３０対こより下向きの光に転向した前記下向きの光４１により、下面への光量を増加させ、前記反射板３０に設けられた光透過部３１を介して上向に出る光４２の一部を天井面側に透過させる。
【０００６】
【発明の効果】
外観が板状を呈しその両板面から光が出る面形蛍光ランプにおいて、通常任意の被照射面に光を向けられるのは片方の板面から発生する光のみであるが、もう一方の板面から発生する光の一部をもう一方へ反射させ、かつ一部の光は反射させずに使用することにより、各板面より発生する光を有効に使用できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lighting device using a fluorescent lamp.
[0002]
[Prior art]
In the prior art, there was no lighting fixture using a planar fluorescent lamp in which the appearance was plate-like and light was emitted from both plate surfaces.
[0003]
[Problems to be solved by the invention]
In a surface-type fluorescent lamp that has a plate-like appearance and emits light from both plate surfaces, light can normally be directed to any surface to be illuminated only by light generated from one plate surface, and the other plate surface It is necessary to effectively use the light generated from the light. The present invention solves this.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a part of the light generated from one plate surface (A) of a surface-type fluorescent lamp having a plate-like appearance from which light is emitted from both plate surfaces is partially used on the other plate surface (B). A reflector that reflects any necessary light is set on the single-plate surface (instep) side.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The surface-type fluorescent lamp 10 is provided with a surface-type fluorescent lamp 10 having a plate-like appearance, and light is emitted from both surfaces of the plate-like fluorescent lamp. The fixture body 20 holding the surface-type fluorescent lamp 10 is provided. A reflector 30 is disposed on the upper surface 11 of the planar fluorescent lamp 10 so as to diverge upwardly directed light 42 into downwardly directed light 41. The lower surface 12 of the planar fluorescent lamp 10 The amount of light to the lower surface is reduced by the downward light 41 which is obtained by turning the light 40 emitted downward to the side and the light 42 emitted upward to the upper surface 11 side of the planar fluorescent lamp 10 into the reflector 30 and the downward light. The light 42 is increased, and a part of the light 42 emitted upward through the light transmission part 31 provided on the reflection plate 30 is transmitted to the ceiling surface side.
[0006]
【The invention's effect】
In a surface-type fluorescent lamp whose appearance is plate-like and light is emitted from both plate surfaces, light can normally be directed to any surface to be irradiated, while only light generated from one plate surface is used, but the other plate Light generated from each plate surface can be used effectively by reflecting some of the light generated from the surface to the other and not reflecting some of the light.
