光源１１としては、特に制限するものではないが、例えば、ＬＥＤ、ＬＤ（Ｌａｓｅｒ Ｄｉｏｄｅ）、有機ＥＬ（Ｏｒｇａｎｉｃ Ｅｌｅｃｔｏｒｏ−Ｌｕｍｉｎｅｓｃｅｎｃｅ）、無機ＥＬ（Ｉｎｏｒｇａｎｉｃ Ｅｌｅｃｔｏｒｏ−Ｌｕｍｉｎｅｓｃｅｎｃｅ）等があげられ、これらの中でも、ＬＥＤが好ましい。ＬＥＤは、特に限定されず、従来公知のものを使用できるが、白色ＬＥＤであることが好ましい。光源１１は、例えば、シリコーン樹脂等に内包され、前記シリコーン樹脂中に蛍光体が分散されていてもよい。このような態様においては、例えば、光源１１を、青色ＬＥＤとし、前記蛍光体を、黄色蛍光体または赤・緑蛍光体の組み合わせとすることで、白色光を得ることができる。また、光源１１を、近紫外ＬＥＤ（ＵＶ−ＬＥＤ）とし、前記蛍光体を、赤・緑・青蛍光体の組み合わせ（ＲＧＢ蛍光体）とすることでも、白色光を得ることができる。   Although it does not restrict | limit especially as the light source 11, For example, LED, LD (Laser Diode), organic EL (Organic Electric-Luminescence), inorganic EL (Inorganic Electro-Luminescence) etc. are mention | raise | lifted, Among these, LED is mentioned. Is preferred. Although LED is not specifically limited, A conventionally well-known thing can be used, but it is preferable that it is white LED. For example, the light source 11 may be included in a silicone resin or the like, and a phosphor may be dispersed in the silicone resin. In such an embodiment, for example, white light can be obtained by using the light source 11 as a blue LED and the phosphor as a combination of a yellow phosphor or a red / green phosphor. Also, white light can be obtained by using a light source 11 as a near-ultraviolet LED (UV-LED) and the phosphor as a combination of red, green and blue phosphors (RGB phosphor).

図１（Ｂ）に示すように、筐体１２は、底面１２ａおよび２つのリフレクタ１２ｂで構成されている。底面１２ａおよび２つのリフレクタ１２ｂは、図１（Ｂ）に示すように、複数の部材で構成されていてもよいし、一体成型されていてもよい。   As shown in FIG. 1B, the housing 12 includes a bottom surface 12a and two reflectors 12b.

底面１２ａの形成材料としては、金属板が好ましい。前記金属板の板厚は、特に限定されないが、例えば、２〜３ｍｍである。前記金属としては、例えば、アルミニウムおよびその合金、マグネシウムおよびその合金、鉄およびその合金、銅およびその合金、チタンおよびその合金等があげられる。マグネシウムおよびその合金を用いれば、より軽量化することが可能となる。鉄およびその合金を用いれば、製造コストをより低減可能となる。銅およびその合金を用いれば、放熱特性をより向上可能となる。チタンおよびその合金を用いれば、強度をより向上可能となる。   As a material for forming the bottom surface 12a, a metal plate is preferable. Although the plate | board thickness of the said metal plate is not specifically limited, For example, it is 2-3 mm. Examples of the metal include aluminum and its alloys, magnesium and its alloys, iron and its alloys, copper and its alloys, titanium and its alloys, and the like. If magnesium and its alloy are used, the weight can be further reduced. If iron and its alloys are used, the manufacturing cost can be further reduced. If copper and its alloy are used, the heat dissipation characteristics can be further improved. If titanium and its alloy are used, the strength can be further improved.

リフレクタ１２ｂの形成材料としては、例えば、アルミニウムおよびその合金、マグネシウムおよびその合金等の金属；ポリカーボネート（ＰＣ）、ポリブチレンテレフタレート（ＰＢＴ）等の樹脂；等があげられる。リフレクタ１２ｂとしては、例えば、反射面にメッキ、高反射塗料の塗布等の高反射加工を施すことで、反射効率を向上させたものを用いることが好ましい。リフレクタ１２ｂの断面形状は、図１（Ｂ）に例示するような円弧状であってもよいし、直線状であってもよい。リフレクタ１２ｂは、例えば、押出成形等により製造可能である。   Examples of the material for forming the reflector 12b include metals such as aluminum and alloys thereof, magnesium and alloys thereof; resins such as polycarbonate (PC) and polybutylene terephthalate (PBT); and the like. As the reflector 12b, for example, it is preferable to use a reflector whose reflection efficiency is improved by applying high reflection processing such as plating or application of a high reflection paint to the reflection surface. The cross-sectional shape of the reflector 12b may be an arc as illustrated in FIG. 1B or may be a straight line. The reflector 12b can be manufactured by, for example, extrusion molding.

筐体１２の開口面積は、図１（Ｂ）に例示するように、底面１２ａの面積より大きくてもよいし、底面１２ａと同じであってもよい。   As illustrated in FIG. 1B, the opening area of the housing 12 may be larger than the area of the bottom surface 12a or the same as the bottom surface 12a.

光反射部１３の形成材料としては、特に限定されず、照射された光の大部分を透過せず、反射する材料であればいかなるものであってもよいが、例えば、アルミニウム、光反射率の高い樹脂（例えば、ＰＣ、ポリエチレンテレフタレート（ＰＥＴ）等）等があげられる。光反射部１３の形状は、光源１１が発した光の一部を、リフレクタ１２ｂ方向へと反射可能な形状であれば特に限定されず、例えば、図１（Ｂ）に示す略円錐状である。また、光反射部１３は、例えば、図２（Ａ）〜（Ｆ）に示す形状であってもよく、これら以外の形状であってもよい。光反射部１３は、例えば、押出成形等により製造可能である。   The material for forming the light reflecting portion 13 is not particularly limited, and any material can be used as long as the material does not transmit and reflect most of the irradiated light. Examples thereof include high resins (for example, PC, polyethylene terephthalate (PET), etc.). The shape of the light reflecting portion 13 is not particularly limited as long as a part of the light emitted from the light source 11 can be reflected in the direction of the reflector 12b. For example, the light reflecting portion 13 has a substantially conical shape shown in FIG. . Moreover, the shape shown in FIG. 2 (A)-(F) may be sufficient as the light reflection part 13, for example, and shapes other than these may be sufficient as it. The light reflecting portion 13 can be manufactured by, for example, extrusion molding.

前述のとおり、光反射部１３は、筐体１２の光源１１より開口側であって、その面方向の中心が、光源１１の面方向の中心を通り、且つ、光源１１の面方向に対する垂直方向の線上に位置する。光源１１から光反射部１３上端までの距離は、例えば、０ｃｍを超えて５０ｃｍ以下、１ｃｍ〜１０ｃｍ、２ｃｍ〜５ｃｍである。   As described above, the light reflecting portion 13 is on the opening side of the light source 11 of the housing 12, and the center of the surface direction passes through the center of the surface direction of the light source 11 and is perpendicular to the surface direction of the light source 11. Located on the line. The distance from the light source 11 to the upper end of the light reflection part 13 is, for example, more than 0 cm and 50 cm or less, 1 cm to 10 cm, and 2 cm to 5 cm.

図３を用いて、光源１１の設置面積と光反射部１３の大きさとの関係の一例について説明する。光反射部１３は、光源１１の面方向の中心と光反射部１３の面方向の中心とを結ぶ線上において、光反射部１３を介して光源１１を見たときに、光反射部１３による光源１１の発する光の遮蔽率（図３における光源１１を示す円１１ａの面積に占める光反射部１３を示す円１３ａの面積の割合）が、例えば、９０％〜１５０％、９０％〜１１０％となる大きさである。前記遮蔽率は、光源１１と光反射部１３との間の距離が長いほど、より小さな光反射部１３でも高くなる。このため、光反射部１３の大きさは、光源１１の設置面積、光源１１と光反射部１３との間の距離等に応じて、適宜調整することが好ましい。なお、図３においては、わかりやすさを考慮して円１３ａを黒塗りとしているに過ぎず、光反射部１３の色を黒に限定するものではなく、また、光源１１および光反射部１３下部の形状を円に限定するものでもない。   An example of the relationship between the installation area of the light source 11 and the size of the light reflecting portion 13 will be described with reference to FIG. When the light reflection unit 13 views the light source 11 through the light reflection unit 13 on a line connecting the center of the surface direction of the light source 11 and the center of the surface direction of the light reflection unit 13, the light reflection unit 13 emits light from the light reflection unit 13. 11 (the ratio of the area of the circle 13a indicating the light reflecting portion 13 to the area of the circle 11a indicating the light source 11 in FIG. 3) is 90% to 150%, 90% to 110%, for example. Is the size. The smaller the light reflection portion 13 is, the higher the shielding ratio is as the distance between the light source 11 and the light reflection portion 13 is longer. For this reason, it is preferable that the size of the light reflecting portion 13 is appropriately adjusted according to the installation area of the light source 11, the distance between the light source 11 and the light reflecting portion 13, and the like. In FIG. 3, the circle 13 a is simply painted in black for easy understanding, and the color of the light reflecting portion 13 is not limited to black, and the shapes of the lower portions of the light source 11 and the light reflecting portion 13 are not limited. Is not limited to a circle.

光反射部１３は、前記線上に位置すればよく、その配置方法は特に限定されないが、例えば、図１（Ｂ）に示すように、光源１１を覆う光透過性の光源カバー１５に配置されることが好ましい。光源カバー１５の形成材料としては、例えば、ＰＣ、アクリル、ガラス等があげられる。光源カバー１５は、例えば、押出成形等により製造可能である。光源カバー１５は、パッキン１６を含むことが好ましい。光源カバー１５にパッキン１６を含ませれば、照明装置１０の防水性を、より高めることができる。   The light reflecting portion 13 may be positioned on the line, and the arrangement method is not particularly limited. For example, as illustrated in FIG. 1B, the light reflecting portion 13 is disposed on a light transmissive light source cover 15 that covers the light source 11. It is preferable. Examples of the material for forming the light source cover 15 include PC, acrylic, and glass. The light source cover 15 can be manufactured by, for example, extrusion molding. The light source cover 15 preferably includes a packing 16. If the packing 16 is included in the light source cover 15, the waterproofness of the lighting device 10 can be further enhanced.

The material for forming the thermal diffusion portion 14 may be, for example, a resin containing a high thermal conductive filler. Examples of the resin include PBT, PET, PC, polyamide (PA), polyphenylene sulfide (PPS), polymethyl methacrylate (PMMA), and the like. Furthermore, the material for forming the thermal diffusion section 14 may be a composite material of, for example, graphite or carbon fiber and a metal such as aluminum or copper.
