Similarly, on the light guide plate 22 of the light emitting unit 20, a concave pattern that generates diffused light, a convex pattern, or a pattern 22p composed of concave and convex patterns corresponds to a side surface orthogonal to the incident surface 21f. It is formed in a matrix with respect to one main surface and the other main surface opposite to the one main surface. The interval between such patterns 21p and 22p is, for example, 1 mm to 6 mm.
また、発光部２０の光学特性に関し、例えば、導光板２１の入射面２１ｆから入射された光源１１の光の一部は、例えば４つに分岐した導光片２１ａ乃至導光片２１ｄの間にそれぞれ形成された３つの切欠部２１ｋ乃至切欠部２１ｎにより、それぞれ広角に反射させることができる。ここで、切欠部２１ｋ乃至切欠部２１ｎで広角に反射された光の一部は、導光片２１ａ乃至導光片２１ｄにそれぞれ設けられた一主面と該一主面に対向した他主面の間を多重反射する過程で、該一主面又は該他主面から出射される。すなわち、導光板２１の入射面２１ｆから入射された光源１１の光を、入射面２１ｆに対向して形成された先端２１ｓ及び先端２１ｔに加えて、入射面２１ｆに直交した側面からも出射させることができる。また、導光片２１ａ乃至導光片２１ｄにおいて、入射面２１ｆに直交した側面は、それぞれ４面形成されている。したがって、導光片２１ａ乃至導光片２１ｄにおいて、２面から構成された一主面と該一主面に対向した他主面が、２組形成されている。 Further, regarding the optical characteristics of the light emitting unit 20, for example, part of the light of the light source 11 incident from the incident surface 21f of the light guide plate 21 is, for example, between the light guide pieces 21a to 21d branched into four. Each of the three notches 21k to 21n formed can be reflected at a wide angle. Here, a part of the light reflected at a wide angle by the notch 21k to the notch 21n includes one main surface provided on each of the light guide pieces 21a to 21d and the other main surface facing the one main surface. The light is emitted from the one main surface or the other main surface in the process of multiple reflection between the two. That is, the light of the light source 11 incident from the incident surface 21f of the light guide plate 21 is emitted from the side surface orthogonal to the incident surface 21f in addition to the tip 21s and the tip 21t formed to face the incident surface 21f. Can do. Further, in the light guide pieces 21a to 21d, four side surfaces orthogonal to the incident surface 21f are formed. Therefore, in the light guide piece 21a to the light guide piece 21d, two sets of one main surface composed of two surfaces and the other main surface opposed to the one main surface are formed.
ここで、発光部２０の光学特性に関し、入射面２１ｆに直交した４つの側面の中、１つの側面で反射した光がその１つの側面に対向した側面に入射され、入射された光の一部が該対向した側面から出射される。同様に、入射面２１ｆに直交した４つの側面の中、１つの側面で反射した光がその１つの側面に隣接した側面に入射され、入射された光の一部が、該隣接した側面から出射される。さらに、導光板２１に入射した光は、導光板２１の各面の間で全方位に反射することにより例えば先端２１ｓ又は先端２１ｔに斜入射で入射された後、該先端２１ｓ又は先端２１ｔから出射されずに入射面２１ｆ側に反射される。したがって、導光板２１では、該導光板２１の入射面２１ｆから入射した光源１１の光の中、直進して先端２１ｓ又は先端２１ｔから出射される光の割合を、大幅に減少させることができる。一方、導光板２１の入射面２１ｆから入射した光源１１の光の中、入射面２１ｆに直交した４つの側面から出射される光の割合を、大幅に増加させることができる。さらに、４面の中の対向する２面にはパターン２１ｐがマトリクス状に形成されていることから、複数のパターン２１ｐで生成された拡散光が、４面の中の対向する２面から均一な面光源として出射される。すなわち、導光板２１からは、配光角が非常に大きく且つ十分に拡散され目に優しい光が出射される。 Here, regarding the optical characteristics of the light emitting unit 20, the light reflected by one of the four side surfaces orthogonal to the incident surface 21 f is incident on the side surface facing the one side surface, and a part of the incident light. Are emitted from the opposite side surfaces. Similarly, of the four side surfaces orthogonal to the incident surface 21f, the light reflected by one side surface is incident on the side surface adjacent to the one side surface, and a part of the incident light is emitted from the adjacent side surface. Is done. Further, the light incident on the light guide plate 21 is reflected in all directions between the surfaces of the light guide plate 21 so as to be incident on the tip 21s or the tip 21t at an oblique incidence and then emitted from the tip 21s or the tip 21t. Without being reflected to the incident surface 21f side. Therefore, in the light guide plate 21, the ratio of the light that travels straight and is emitted from the tip 21s or the tip 21t in the light of the light source 11 incident from the incident surface 21f of the light guide plate 21 can be greatly reduced. On the other hand, the ratio of the light emitted from the four side surfaces orthogonal to the incident surface 21f in the light of the light source 11 incident from the incident surface 21f of the light guide plate 21 can be significantly increased. Further, since the patterns 21p are formed in a matrix on the two opposing surfaces of the four surfaces, the diffused light generated by the plurality of patterns 21p is uniform from the two opposing surfaces of the four surfaces. It is emitted as a surface light source. That is, the light guide plate 21 emits light that has a very large light distribution angle and is sufficiently diffused and gentle to the eyes.

Such a power supply board 31 is composed of components 32 such as a transformer, a rectifier, and a capacitor. Regarding the configuration of the power supply substrate 31, when a fluorescent tube, a cold cathode tube, or a neon tube is used as the light source 11 of the light source unit 10, AC power supplied from the outside is used without being converted to DC. The power supply unit 30 is accommodated in a power supply accommodation unit 40 described later. Further, the end portion 31a of the power supply substrate 31 is urged and fixed by a minute protrusion 42u formed in a groove 42b of a second power supply housing case 42 described later. Further, the wiring 31b is connected to a base 55 of the casing unit 50 described later. Similarly, the wiring 31c is connected to the light source substrate 12 of the light source unit 10 described above.

A filler is filled between the parts 32. As shown in FIGS. 1 to 5, such a power supply accommodating portion 40 includes a first power supply accommodating case 41, a second power accommodating case 42, and a filler 48. Hereinafter, the structure of the power supply accommodating part 40 is demonstrated. The first power supply housing case 41 and the second power supply housing case 42 are separately formed into two so as to form a cylindrical shape having a space inside when joined. The first power supply housing case 41 is made of plastics, for example, and is formed by combining a cylindrical shape and a semicylindrical shape. Similarly, the second power supply housing case 42 is made of, for example, transparent plastics at least partially, and is formed in a semicylindrical shape as a whole. Therefore, the inside of the second power supply housing case 42 can be recognized from the outside through the outer wall 42f and the inner wall 42a. The power supply accommodating portion 40 is not limited to a configuration including two power supply accommodating cases combined with each other. For example, the first power accommodating case 41 and the second power accommodating case 42 are integrally formed. Also good. Similarly, the power storage unit 40 may include three or more power storage cases that are combined with each other. Furthermore, the power supply accommodating part 40 is not limited to the shape which consists of a cylindrical shape, For example, a cross section is good also as a shape which consists of polygonal column shapes, such as a square and a hexagon.
ここで、第１の実施形態の照明装置１を構成する電源収容部４０に関し、例えば図５（ａ）に示す様に、第１の電源収容ケース４１の内壁４１ａと、第２の電源収容ケース４２の内壁４２ａとの間に設けられた内部の空間に、電源部３０の電源基板３１が収容される。具体的には、図５（ａ）に示す第１の電源収容ケース４１の内壁４１ａと外壁４１ｆの間に形成された一対の溝４１ｂと、図５（ｂ）に示す第２の電源収容ケース４２の内壁４２ａと外壁４２ｆの間に形成された一対の溝４２ｂで、電源部３０の電源基板３１の両側に設けられた端部３１ａが挟み込まれて係合された状態で、電源部３０の電源基板３１が電源収容部４０に収容される。なお、電源部３０の電源基板３１の両側に設けられた端部３１ａは、図５（ｂ）に示す第２の電源収容ケース４２の溝４２ｂに形成された微小な突起４２ｕで付勢されて固定される。ここで、例えば図５（ａ）に示す第２の電源収容ケース４２の少なくとも一部分が透明部材から成るため、該第２の電源収容ケース４２の外壁４２ｆから内壁４２ａを介して、内部に収容された電源部３０の電源基板３１や該電源基板３１に実装された部品３２が認識可能である。 Here, regarding the power supply accommodating part 40 which comprises the illuminating device 1 of 1st Embodiment, as shown, for example to Fig.5 (a), the inner wall 41a of the 1st power supply accommodating case 41, and the 2nd power supply accommodating case The power supply board 31 of the power supply unit 30 is accommodated in an internal space provided between the inner wall 42a of the 42. Specifically, a pair of grooves 41b formed between the inner wall 41a and the outer wall 41f of the first power supply housing case 41 shown in FIG. 5 (a), and the second power supply housing case shown in FIG. 5 (b). The pair of grooves 42b formed between the inner wall 42a and the outer wall 42f of 42 are inserted into and engaged with the end portions 31a provided on both sides of the power supply substrate 31 of the power supply unit 30. The power supply substrate 31 is accommodated in the power supply accommodating portion 40. The end portions 31a provided on both sides of the power supply substrate 31 of the power supply unit 30 are urged by minute protrusions 42u formed in the grooves 42b of the second power supply housing case 42 shown in FIG. Fixed. Here, for example, since at least a part of the second power supply housing case 42 shown in FIG. 5A is made of a transparent member, it is housed inside from the outer wall 42f of the second power supply housing case 42 through the inner wall 42a. The power supply board 31 of the power supply unit 30 and the component 32 mounted on the power supply board 31 can be recognized.
また、電源収容部４０に関し、図４（ａ）に示す第１の電源収容ケース４１の端部４１ｇと、第２の電源収容ケース４２の端部４２ｇは、光源部１０の光源基板１２の裏面に当接する。また、第１の電源収容ケース４１の端部４１ｇの一部からそれぞれ突出して半円筒形状に形成された一対の配線挿通部４１ｃと、第２の電源収容ケース４２の端部４２ｇの一部からそれぞれ突出して半円筒形状に形成された一対の配線挿通部４２ｃは、それぞれ係合した場合に円筒形状になり、光源部１０の光源基板１２に形成された孔１２ｂに挿入される。ここで、図４（ａ）に示すように、第１の電源収容ケース４１の配線挿通部４１ｃ及び第２の電源収容ケース４２の配線挿通部４２ｃは、それぞれ係合した場合に貫通孔が形成され、該貫通孔に配線３１ｃを通す。また、図５（ｂ）に示す第１の電源収容ケース４１は、円筒形状の部分に、例えばネジ山が形成された係合部４１ｓを設け、後述する筐体部５０の口金５５の内周面に形成されたネジ溝に係合される。 In addition, with respect to the power supply accommodation section 40, the end 41 g of the first power supply accommodation case 41 and the end 42 g of the second power supply accommodation case 42 shown in FIG. Abut. Further, a pair of wiring insertion portions 41 c that are respectively formed in a semi-cylindrical shape projecting from a part of the end portion 41 g of the first power supply housing case 41 and a part of the end portion 42 g of the second power supply housing case 42. The pair of wiring insertion portions 42 c that protrude from each other and are formed into a semicylindrical shape are cylindrical when engaged with each other, and are inserted into the holes 12 b formed in the light source substrate 12 of the light source unit 10. Here, as shown in FIG. 4 (a), the wiring insertion part 41c of the first power supply accommodation case 41 and the wiring insertion part 42c of the second power supply accommodation case 42 are each formed with a through hole. The wiring 31c is passed through the through hole. Further, the first power supply housing case 41 shown in FIG. 5B is provided with an engaging portion 41 s formed with, for example, a screw thread in a cylindrical portion, and an inner periphery of a base 55 of the housing portion 50 described later. It is engaged with a thread groove formed on the surface.
さらに、電源収容部４０に関し、図４（ａ）及び図５の各図に示すように、第２の電源収容ケース４２の内壁４２ａの一部には、内部に向かって突出した突出部４２ｐが形成されている。したがって、図４（ｂ）に示すように、第１の電源収容ケース４１及び第２の電源収容ケース４２で、電源部３０の電源基板３１を挟み込んで収容した場合に、該電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの距離が短くなる。ここで、充填材４８に相当する大気中の水分と化学反応して硬化する接着剤、光硬化性樹脂、又は熱硬化性樹脂を、該電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの隙間に充填すると、充填材４８の厚みが薄くても、該充填材４８が部品３２と突出部４２ｐとの隙間に十分に充填され密着するため、充填材４８を硬化させ易くすることができ、且つ充填材４８の使用量を抑制することができる。 Further, regarding the power supply accommodating portion 40, as shown in FIGS. 4A and 5, each of the inner walls 42a of the second power supply accommodating case 42 has a protruding portion 42p protruding toward the inside. Is formed. Therefore, as shown in FIG. 4B, when the power supply board 31 of the power supply unit 30 is sandwiched and accommodated between the first power supply accommodation case 41 and the second power supply accommodation case 42, it is mounted on the power supply board 31. The distance between the formed component 32 and the protrusion 42p formed in the second power supply housing case 42 is shortened. Here, an adhesive that is chemically reacted with moisture in the atmosphere corresponding to the filler 48, a photo-curing resin, or a thermosetting resin is mounted on the component 32 mounted on the power supply substrate 31, and the second If the gap between the power supply housing case 42 and the protruding portion 42p is filled, the filler 48 is sufficiently filled in and closely adhered to the gap between the component 32 and the protruding portion 42p even if the thickness of the filler 48 is thin. The filler 48 can be easily cured, and the amount of the filler 48 used can be suppressed.
また、電源収容部４０の第２の電源収容ケース４２の内壁４２ａに形成された突出部４２ｐの先端面の形状に関し、図６（ａ）に突出部４２ｐの先端面が平面に形成された第２の電源収容ケース４２を示している。一方、図６（ｂ）に突出部４３ｑの先端面に溝から成る凹状部が複数形成された第２の電源収容ケース４３を示している。さらに、図６（ｃ）に突出部４４ｒの先端面に凹状部が複数形成された第２の電源収容ケース４４を示している。ここで、図６（ａ）に示す第２の電源収容ケース４２に形成された突出部４２ｐと比較して、図６（ｂ）に示す第２の電源収容ケース４３に形成された突出部４３ｑの方が表面積が増大し充填材との密着性が向上するため、放熱性を有する充填材を塗布した場合に、電源部３０の電源基板３１に実装された部品３２で発生した熱を、より効果的に放熱することができる。また、第２の電源収容ケース４２に形成された突出部４２ｐと比較して、第２の電源収容ケース４３に形成された突出部４３ｑの方が表面積が増大し充填材との密着性が向上するため、防音性を有する充填材を塗布した場合に、電源部３０の電源基板３１に実装された部品３２で発生した音を、より効果的に音を減衰させることができる。 Further, regarding the shape of the distal end surface of the projecting portion 42p formed on the inner wall 42a of the second power source accommodating case 42 of the power source accommodating portion 40, FIG. 6 (a) shows a first embodiment where the distal end surface of the projecting portion 42p is formed flat. 2 shows a power supply housing case 42. On the other hand, FIG. 6B shows a second power supply housing case 43 in which a plurality of concave portions made of grooves are formed on the front end surface of the protruding portion 43q. Further, FIG. 6C shows a second power supply housing case 44 in which a plurality of concave portions are formed on the front end surface of the protruding portion 44r. Here, as compared with the protrusion 42p formed in the second power supply housing case 42 shown in FIG. 6A, the protrusion 43q formed in the second power supply housing 43 shown in FIG. 6B. Since the surface area increases and the adhesiveness with the filler improves, the heat generated in the component 32 mounted on the power supply substrate 31 of the power supply unit 30 when the filler with heat dissipation is applied is more Heat can be effectively dissipated. In addition, the protrusion 43q formed in the second power supply housing case 43 has a larger surface area and improved adhesion to the filler compared to the protrusion 42p formed in the second power supply storage case 42. Therefore, when a sound-proof filler is applied, the sound generated by the component 32 mounted on the power supply board 31 of the power supply unit 30 can be attenuated more effectively.
同様に、電源収容部４０の第２の電源収容ケース４２の内壁４２ａに形成された突出部４２ｐの先端面の形状に関し、第２の電源収容ケース４２に形成された突出部４２ｐと比較して、第２の電源収容ケース４３に形成された突出部４３ｑの方が表面積が増大し充填材との密着性が向上するため、防振性を有する充填材を塗布した場合に、電源部３０の電源基板３１に実装された部品３２で発生した振動、又は外部から電源部３０の電源基板３１に実装された部品３２に対して伝播した振動を、より効果的に振動を減衰させることができる。なお、図６（ｃ）に示す第２の電源収容ケース４４に形成された突出部４４ｒについても、図６（ｂ）に示す第２の電源収容ケース４３に形成された突出部４３ｑと同様に、より効果的な放熱性、防音性、及び防振性を得ることができる。 Similarly, the shape of the front end surface of the protruding portion 42p formed on the inner wall 42a of the second power supply housing case 42 of the power supply housing portion 40 is compared with the protruding portion 42p formed on the second power supply housing case 42. Since the protrusion 43q formed on the second power supply housing case 43 has a larger surface area and improved adhesion to the filler, the anti-vibration filler is applied when the filler 30 is applied. The vibration generated in the component 32 mounted on the power supply substrate 31 or the vibration propagated from the outside to the component 32 mounted on the power supply substrate 31 of the power supply unit 30 can be attenuated more effectively. Note that the protrusion 44r formed in the second power supply housing case 44 shown in FIG. 6C is also the same as the protrusion 43q formed in the second power supply housing case 43 shown in FIG. 6B. More effective heat dissipation, soundproofing and vibration isolation can be obtained.
また、電源収容部４０の第２の電源収容ケース４２の内壁４２ａに形成された突出部４２ｐの先端面の形状に関し、図７（ａ）乃至図７（ｊ）を参照しながら説明する。なお、図７（ａ）乃至図７（ｊ）には、例えば、突出部の先端面に対してマトリクス状で点状に複数形成された凹状部又は凸状部の１つを断面で図示している。同様に、図７（ａ）、図７（ｂ）、及び図７（ｇ）乃至（ｊ）には、例えば、突出部の先端面に対して所定の間隔で複数形成された溝から成る凹状部の１つを断面で図示している。具体的には、図７（ａ）に所定の深さの凹状部が複数形成された突出部６０ｓの一部を断面図で示している。また、図７（ｂ）に所定の高さの凸状部が複数形成された突出部６１ｓの一部を断面図で示している。同様に、図７（ｃ）に角錐形状の凹状部が複数形成された突出部６２ｓの一部を断面図で示している。同様に、図７（ｄ）に角錐形状の凸状部が複数形成された突出部６３ｓの一部を断面図で示している。同様に、図７（ｅ）に角錐台形状の凹状部が複数形成された突出部６４ｓの一部を断面図で示している。 Further, the shape of the tip end surface of the protrusion 42p formed on the inner wall 42a of the second power supply housing case 42 of the power supply housing 40 will be described with reference to FIGS. 7 (a) to 7 (j). 7A to 7J, for example, one of a plurality of concave portions or convex portions formed in a matrix in a dot shape with respect to the tip surface of the protruding portion is shown in cross section. ing. Similarly, in FIGS. 7A, 7B, and 7G to 7J, for example, a concave shape including a plurality of grooves formed at a predetermined interval with respect to the distal end surface of the protrusion. One of the parts is shown in cross section.

次に、例えば照明装置１に配設される２つに分離された片方の電源収容部４０に相当する第２の電源収容ケース４２の突出部４２ｐに対して充填材４８を充填して該充填材４８を硬化させる方法について、図１０乃至図１３を参照しながら説明する Next, for example, the filling material 48 is filled into the projecting portion 42p of the second power supply housing case 42 corresponding to one of the two power supply housing portions 40 disposed in the lighting device 1 and filled. A method of curing the material 48 will be described with reference to FIGS. 10 to 13.
第２の電源収容ケース４２の突出部４２ｐに対して充填材４８を充填して該充填材４８を硬化させる方法に関し、図１０には、照明装置１に配設される第２の電源収容ケース４２の突出部４２ｐに対して、充填機Ａを用いて、充填材４８に相当する大気中の水分と化学反応して硬化する接着剤、光硬化性樹脂、又は熱硬化性樹脂を滴下している状態を模式図で示している。また、第２の電源収容ケース４２は、治具Ｄに載置されている。なお、治具Ｄは、第１の電源収容ケース４１及び第２の電源収容ケース４２の外形形状に合わせて、傾斜した内周面が形成されている。また、充填機ＡのシリンジＡ１に充填材４８を注入した上で、シリンジＡ１に接続された送圧チューブＡ２に対して、制御パネルＡ３で設定した圧力と時間で空気を射出し、シリンジＡ１内の充填材４８を、第２の電源収容ケース４２の突出部４２ｐに滴下する。なお、シリンジＡ１は、シリンジ台Ａ４に載置されている。ここで、充填材４８に大気中の水分と化学反応して硬化する接着剤を用いた場合には、所定の時間内に、第１の電源収容ケース４１及び第２の電源収容ケース４２で電源部３０の電源基板３１を挟むようにして収容し、充填材４８を硬化させる。 FIG. 10 shows a second power supply housing case disposed in the lighting device 1 in relation to a method of curing the filler material 48 by filling the protruding portion 42p of the second power supply housing case 42 with the filler 48. An adhesive, a photocurable resin, or a thermosetting resin that is cured by a chemical reaction with moisture in the atmosphere corresponding to the filler 48 is dropped onto the protrusion 42p of 42 using the filling machine A. The state is shown in a schematic diagram. Further, the second power supply housing case 42 is placed on the jig D. In addition, the jig | tool D has the inclined internal peripheral surface according to the external shape of the 1st power supply storage case 41 and the 2nd power supply storage case 42. As shown in FIG. Moreover, after injecting the filler 48 into the syringe A1 of the filling machine A, air is injected into the pressure feeding tube A2 connected to the syringe A1 at the pressure and time set in the control panel A3, and the syringe A1 The filler 48 is dropped onto the protrusion 42 p of the second power supply housing case 42.

The state which has dripped the filler 48 using the filling machine A with respect to the protrusion part 42p of 2 power supply storage cases 42 is shown with the schematic diagram. On the other hand, FIG. 11B schematically shows a state in which the filler 48 is dropped using the filling machine A onto the component 32 mounted on the power supply substrate 31 of the power supply unit 30. As described above, the filler 48 may be dropped on the projecting portion 42p of the second power supply housing case 42 depending on the specifications of the filler 48, the work efficiency related to the assembly of the lighting device 1, and the like. May be dropped on the component 32 mounted on the power supply substrate 31 of the power supply unit 30. Specifically, for example, the viscosity of the filler 48 is low, and the surface area of the protruding portion 42p of the second power supply housing case 42 is larger than the surface area of the component 32 mounted on the power supply substrate 31 of the power supply unit 30. In this case, the filler 48 is dropped on the protruding portion 42p of the second power supply housing case 42 in order to prevent the dropped filler 48 from sagging and diffusing around.
また、第２の電源収容ケース４２の突出部４２ｐに対して充填材４８を充填して該充填材４８を硬化させる方法に関し、図１２には、図１０を参照しながら前述したように照明装置１に配設される第２の電源収容ケース４２の突出部４２ｐに対して、充填材４８に相当する光硬化性樹脂が滴下され、更に第１の電源収容ケース４１及び第２の電源収容ケース４２で電源部３０の電源基板３１を挟むようにして収容された後に、電源収容部４０の内部に充填された光硬化性樹脂を、紫外線照射装置Ｂを用いて硬化させている状態を模式図で示している。なお、電源基板３１は、治具Ｄに載置された第１の電源収容ケース４１及び第２の電源収容ケース４２の内部に収容されている。また、紫外線照射装置ＢのファイバＢ１を、第２の電源収容ケース４２の透明な部分に対向させた上で、制御パネルＢ２で設定した光量と時間で紫外線を照射する。なお、ファイバＢ１は、ファイバ台Ｂ３に載置されている。 In addition, regarding the method of filling the filling material 48 into the protruding portion 42p of the second power supply housing case 42 and curing the filling material 48, as shown in FIG. 12 with reference to FIG. A photocurable resin corresponding to the filler 48 is dropped on the protruding portion 42p of the second power supply housing case 42 disposed in the first power supply case 41, and the first power supply housing case 41 and the second power supply housing case. 42 schematically shows a state in which the photocurable resin filled in the power supply accommodating portion 40 is cured using the ultraviolet irradiation device B after being accommodated so as to sandwich the power supply substrate 31 of the power supply portion 30 at 42. ing. The power supply substrate 31 is accommodated in the first power supply accommodation case 41 and the second power supply accommodation case 42 placed on the jig D. Further, the fiber B1 of the ultraviolet irradiation device B is opposed to the transparent portion of the second power supply housing case 42, and then ultraviolet rays are irradiated with the light amount and time set by the control panel B2. The fiber B1 is placed on the fiber base B3.
さらに、第２の電源収容ケース４２の突出部４２ｐに対して充填材４８を充填して該充填材４８を硬化させる方法に関し、図１３には、図１０を参照しながら前述したように照明装置１に配設される第２の電源収容ケース４２の突出部４２ｐに対して充填材４８に相当する熱硬化性樹脂が滴下され、更に第１の電源収容ケース４１及び第２の電源収容ケース４２で電源部３０の電源基板３１を挟むようにして収容された後に、電源収容部４０の内部に充填された熱硬化性樹脂を、恒温槽Ｃを用いて硬化させている状態を模式図で示している。また、恒温槽Ｃの内部に、電源基板３１を収容した第１の電源収容ケース４１及び第２の電源収容ケース４２を載置し、制御パネルＣ１で設定した温度、湿度、及び時間で、熱硬化性樹脂から成る充填材４８を硬化させる。 Further, the present invention relates to a method of filling the protruding portion 42p of the second power supply housing case 42 with the filler 48 and curing the filler 48. FIG. 13 shows an illumination device as described above with reference to FIG. The thermosetting resin corresponding to the filler 48 is dropped on the protruding portion 42p of the second power supply housing case 42 disposed on the first power supply case 42, and the first power supply case 41 and the second power supply case 42 are further dropped.

以上、本発明に係る照明装置１によれば、装置に収容された電源部材で発生する熱を、簡便な構成により十分に放熱することができる。 As mentioned above, according to the illuminating device 1 which concerns on this invention, the heat which generate | occur | produces with the power supply member accommodated in the apparatus can fully be thermally radiated with a simple structure.
なお、本発明に係る照明装置１は、入射された光源部１０の光を出射する導光板を発光部２０に設ける構成に限定されることはない。具体的には、本発明に係る照明装置１を、例えば、入射された光源部１０の光を出射するレンズ又は保護部材を発光部２０に備えた、一般的な電球型ランプに適用しても良い。 In addition, the illuminating device 1 which concerns on this invention is not limited to the structure which provides in the light emission part 20 the light-guide plate which radiate | emits the light of the incident light source part 10. FIG. Specifically, the lighting device 1 according to the present invention may be applied to, for example, a general light bulb type lamp in which the light emitting unit 20 includes a lens or a protective member that emits light from the incident light source unit 10. good.
ここで、本発明に係る照明装置１によれば、例えば図４（ｂ）に示すように、充填材４８を、電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの隙間に充填することにより、該充填材４８を用いて、部品３２から発熱した熱を放熱させることができ、且つ部品３２から発生した音を減衰させることができ、更に部品３２から発生した振動や外部から部品３２に伝播した振動を減衰させることができる。また、充填材４８を用いて、部品３２が実装された電源基板３１及び第１の電源収容ケース４１を一体に接合することもできる。 Here, according to the lighting device 1 of the present invention, for example, as shown in FIG. 4B, the filler 48 is formed on the component 32 mounted on the power supply substrate 31 and the second power supply housing case 42. By filling the gap between the protruding portion 42p, the heat generated from the component 32 can be dissipated using the filler 48, and the sound generated from the component 32 can be attenuated. Vibration generated from the component 32 and vibration propagated from the outside to the component 32 can be attenuated. In addition, the power supply substrate 31 on which the component 32 is mounted and the first power supply housing case 41 can be integrally joined using the filler 48.
また、本発明に係る照明装置１によれば、例えば図４（ｂ）に示すように、第１の電源収容ケース４１及び第２の電源収容ケース４２で、電源部３０の電源基板３１を挟み込んで収容した場合に、該電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの距離を、短くすることができる。ここで、充填材４８を、該電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの隙間に充填すると、充填材４８の厚みが薄くなるため、充填材４８を硬化させ易くすることができ、且つ充填材４８の使用量を抑制することができる。 Moreover, according to the illuminating device 1 which concerns on this invention, as shown, for example in FIG.4 (b), the power supply board 31 of the power supply part 30 is pinched | interposed by the 1st power supply storage case 41 and the 2nd power supply storage case 42. Can be shortened, the distance between the component 32 mounted on the power supply substrate 31 and the protrusion 42p formed on the second power supply housing case 42 can be shortened. Here, when the filling material 48 is filled in the gap between the component 32 mounted on the power supply substrate 31 and the protruding portion 42p formed in the second power supply housing case 42, the thickness of the filling material 48 becomes thin. The filler 48 can be easily cured, and the amount of the filler 48 used can be suppressed.
さらに、本発明に係る照明装置１によれば、例えば、図６（ａ）に示す第２の電源収容ケース４２に形成された突出部４２ｐと比較して、図６（ｃ）に示す第２の電源収容ケース４４に形成され凹状部を複数設けた突出部４４ｒの方が表面積が増大し充填材との密着性が向上するため、放熱性を有する充填材を塗布した場合に、電源部３０の電源基板３１に実装された部品３２で発生した熱を、より効果的に放熱することができる。具体的には、例えば図７に示すように、電源部３０の電源基板３１に実装された部品３２の仕様に合わせ、電源収容部４０の第２の電源収容ケース４２の内部に形成された突出部の先端面に対して、角錐形状、角錐台形状、円錐形状、円錐台形状、又はそれらを組み合わせた形状から成る凹状部及び凸状部を設けることで、より効果的な放熱性、防音性、及び防振性を得ることができる。 Furthermore, according to the illuminating device 1 which concerns on this invention, compared with the protrusion part 42p formed in the 2nd power supply accommodating case 42 shown to Fig.6 (a), for example, the 2nd shown to FIG.6 (c). The protrusion 44r provided with a plurality of concave portions formed in the power supply housing case 44 has a larger surface area and improved adhesion with the filler, so that when the filler having heat dissipation is applied, the power supply 30 The heat generated in the component 32 mounted on the power supply board 31 can be radiated more effectively. Specifically, for example, as shown in FIG. 7, a protrusion formed inside the second power supply housing case 42 of the power supply housing section 40 in accordance with the specifications of the component 32 mounted on the power supply board 31 of the power supply section 30. More effective heat dissipation and soundproofing by providing a concave part and a convex part made of a pyramid shape, a truncated pyramid shape, a conical shape, a truncated cone shape, or a combination thereof on the tip surface of the part And vibration proofing can be obtained.
また、本発明に係る照明装置１によれば、第２の電源収容ケース４２の少なくとも一部分が透明であることから、内部に設けられた部品３２等の内容物を外部から認識可能である。したがって、本発明に係る照明装置１によれば、図１０を参照しながら前述した充填機Ａを用いて充填材４８を第２の電源収容ケース４２の突出部４２ｐに滴下する場合、第１の電源収容ケース４１及び第２の電源収容ケース４２で電源基板３１を挟むようにして収容する場合、及び図１２を参照しながら前述した紫外線照射装置Ｂを用いて部品３２に滴下された充填材４８を硬化させる場合等に、充填材４８の部品３２等に対する密着具合を外部から確認することができる。 Moreover, according to the illuminating device 1 which concerns on this invention, since at least one part of the 2nd power supply accommodating case 42 is transparent, the contents, such as the components 32 provided in the inside, can be recognized from the outside. Therefore, according to the lighting device 1 according to the present invention, when the filler 48 is dropped onto the protrusion 42p of the second power supply housing case 42 using the filling machine A described above with reference to FIG. When the power supply case 41 and the second power supply case 42 are accommodated so as to sandwich the power supply substrate 31, and the filler 48 dropped on the component 32 is cured using the ultraviolet irradiation device B described above with reference to FIG. For example, the close contact state of the filler 48 with respect to the component 32 or the like can be confirmed from the outside.
なお、本発明に係る照明装置１は、一般的な照明装置の様に電源基板に対して所定の大きさの銅板等から成る放熱部材を設ける構成ではない。すなわち、本発明に係る照明装置１は、電源基板３１において、放熱性、防音性、及び防振性等を有する充填材４８を、電源基板３１に実装された部品３２と、第２の電源収容ケース４２に形成された突出部４２ｐとの隙間に充填して設ける構成であることから、装置の大型化を避けることができる。 In addition, the illuminating device 1 which concerns on this invention is not the structure which provides the heat radiating member which consists of a predetermined size copper plate etc. with respect to a power supply board like a general illuminating device. That is, in the lighting device 1 according to the present invention, the power supply substrate 31 includes the component 32 mounted on the power supply substrate 31 and the second power supply housing the filler 48 having heat dissipation, soundproofing, vibration isolation, and the like. Since it is the structure which fills and provides the clearance gap between the protrusion part 42p formed in the case 42, the enlargement of an apparatus can be avoided.
ここで、本発明に係る照明装置１によれば、例えば図９（ｂ）に示す第２の電源収容ケース４７では、突出部が形成された内壁に対向する外壁４７ｆに窪み部４７ｔを設けていることから、図１２を参照しながら後述する紫外線照射装置Ｂで充填材４８に相当する光硬化性樹脂を硬化させる場合に、窪み部４７ｔを介して突出部に光を透過させ易い。同様に、図９（ｂ）に示す第２の電源収容ケース４７では、図１３を参照しながら後述する恒温槽で充填材４８に相当する熱硬化性樹脂を硬化させる場合に、窪み部４７ｔを介して突出部４７ｐに熱を伝播させ易い。なお、図９（ｂ）に示すように、突出部が形成された内壁に対向する外壁４７ｆに窪み部４７ｔを設ける構成に限定されることはなく、例えば、突出部が形成された内壁から離間した位置に対向した外壁に窪み部を設ける構成としても良い。すなわち、第２の電源収容ケースの円周方向に対して、内壁に形成された突出部と外壁に形成された窪み部とを、離れた位置に形成しても良い。 Here, according to the illuminating device 1 according to the present invention, for example, in the second power supply housing case 47 shown in FIG. 9B, the recess 47t is provided in the outer wall 47f facing the inner wall where the protruding portion is formed. Therefore, when the photocurable resin corresponding to the filler 48 is cured by the ultraviolet irradiation device B described later with reference to FIG. 12, it is easy to transmit the light to the projecting portion through the recess 47t.

You can avoid that. Therefore, according to the lighting device 1 of the present invention, the power supply substrate 31 of the power supply unit 30 is sandwiched between the first power supply housing case 41 and the second power supply housing case 42 as shown in FIG. 4B, for example.

It consists of a certain power supply unit. Such a lighting device according to the second embodiment includes a light source unit 10 that emits light, a light emitting unit 20 that is adjacent to the light source unit 10 and emits light from the incident light source unit 10, and the light source unit. 10 and a power supply unit that supplies a driving power to the light source unit 10 by applying a filler to at least one mounted component. Here, the filler of the power supply unit has, for example, soundproofing and attenuates sound generated by the component. Specifically, if a filler is applied to a component such as a coil mounted on the power supply board of the power supply unit, the sound generated from the component is attenuated by the filler. Moreover, the said filler of the said power supply part has vibration-proof property, for example, and attenuates the vibration propagated with respect to the said power supply part from the inside or the inside of an apparatus. Specifically, if a filler is applied to a component such as a capacitor mounted on the power supply board of the power supply unit, the vibration propagated to the component is attenuated by the filler.
以上、第２の実施形態に係る照明装置によれば、電源部の電源基板に実装された部品に充填材が塗布されていることから、該充填材が防音性を有している場合には、部品で発生した音を減衰させることができる。すなわち、電源部の電源基板に実装されたコイル等の部品に充填材を塗布すれば、部品から発生した音を充填材により減衰させることができることから、照明装置から発生する騒音を防止することができる。また、充填材が防振性を有している場合には、照明装置の外部又は内部から電源部に対して伝播した振動を減衰させることができる。すなわち、電源部の電源基板に実装されたコンデンサ等の部品に充填材を塗布すれば、部品に伝播した振動を充填材により減衰させることができることから、照明装置が部品の端子等の断線等により消灯することを防止することができる。 As mentioned above, according to the illuminating device which concerns on 2nd Embodiment, since the filler is apply | coated to the components mounted in the power supply board of a power supply part, when this filler has soundproofing property The sound generated by the parts can be attenuated. That is, if a filler is applied to a component such as a coil mounted on the power supply board of the power supply unit, the sound generated from the component can be attenuated by the filler, thereby preventing noise generated from the lighting device. it can. In addition, when the filler has vibration proofing properties, vibration propagated from the outside or the inside of the lighting device to the power supply unit can be attenuated. In other words, if a filler is applied to a component such as a capacitor mounted on the power supply board of the power supply unit, the vibration propagated to the component can be attenuated by the filler, so that the lighting device can be broken by disconnection of the terminal of the component, etc. It is possible to prevent the lights from being turned off.

Similarly, in the molding process, a shape reflecting the outer shape of the light guide plate to be molded is formed inside the mold, and for example, a mold softened by heating is injected into the mold mounted on the injection molding machine. Then, the resin is cooled to form a concave pattern, a convex pattern, or a concave and convex pattern on each surface of the light guide plate.
また、発光部２０の導光板２１及び導光板２２の製造方法に関し、シルク印刷加工では、導光板の各面に対して所定の孔が開口した版を当接させ、孔を介して硬化性の樹脂を各面に付着させて、該各面を部分的に樹脂で被覆させることにより、該各面に凸状のパターンを形成する。また、成型加工又はシルク印刷加工に用いる導光板の基材である樹脂に、例えば拡散光を発する微粒子状の拡散部材を添加しても良い。同様に、上述した超音波加工、加熱加工、切削加工、又はレーザ加工を行う導光板の基材である樹脂に、例えば拡散光を発する微粒子状の拡散部材を添加したものを用いても良い。なお、上述した超音波加工、加熱加工、切削加工、レーザ加工、成型加工、及びシルク印刷加工を組み合わせて導光板を形成しても良い。具体的には、例えば成型加工により導光板の外形形状のみを形成した上で、例えば超音波加工により導光板の各面に凹状のパターンを形成しても良い。同様に、例えば成型加工により導光板の外形形状のみを形成した上で、例えばシルク印刷加工により導光板の各面に凸状のパターンを形成しても良い。 In addition, regarding the method for manufacturing the light guide plate 21 and the light guide plate 22 of the light emitting unit 20, in silk printing, a plate having predetermined holes is brought into contact with each surface of the light guide plate, and a curable resin is formed through the holes. A convex pattern is formed on each surface by adhering resin to each surface and partially covering each surface with the resin. Moreover, you may add the fine particle-shaped diffusion member which emits diffused light, for example to resin which is the base material of the light-guide plate used for a shaping | molding process or a silk printing process. Similarly, for example, a resin that is a base material of a light guide plate that performs the above-described ultrasonic processing, heating processing, cutting processing, or laser processing may be added with a particulate diffusion member that emits diffused light. Note that the light guide plate may be formed by a combination of the above-described ultrasonic processing, heating processing, cutting processing, laser processing, molding processing, and silk printing processing. Specifically, for example, after forming only the outer shape of the light guide plate by molding, a concave pattern may be formed on each surface of the light guide plate by, for example, ultrasonic processing. Similarly, after forming only the outer shape of the light guide plate by molding, for example, a convex pattern may be formed on each surface of the light guide plate by silk printing, for example.
