Description

本発明は、照明器具に関する。   The present invention relates to a lighting fixture.

従来、照明器具の光源、例えばＬＥＤ（Light Emitting Diode）は、中実部材（例えば押出材）を用いて形成された重量の大きい光源支持部に取付けることにより、ＬＥＤの放熱効果を高めるようにしていた（例えば、特許文献１参照）。   Conventionally, a light source of a lighting fixture, for example, an LED (Light Emitting Diode) is attached to a heavy light source support portion formed using a solid member (for example, an extruded material) to enhance the heat dissipation effect of the LED. (For example, see Patent Document 1).

特開２００６−３３９０６０号公報（請求項１、段落００２９〜００３１、図３）JP 2006-339060 A (Claim 1, paragraphs 0029 to 0031, FIG. 3)

しかし、従来の照明器具は、光源支持部の重量が大であるため、コストアップになるという問題があった。   However, the conventional lighting fixture has a problem in that the weight of the light source support portion is large, resulting in an increase in cost.

本発明は、逆Ｖ字型の板材からなる複数の光源支持部と、前記各光源支持部における逆Ｖ字形の外向きの傾斜面に設けられた光源と、前記光源支持部及び前記光源を収容する筐体とを備え、前記複数の光源支持部は複数の放熱部材を介して連続して交互に配設され、前記複数の光源支持部と前記放熱部材とは一の板材を折り曲げて一体的に形成され、複数の前記放熱部材は前記筐体に当接している。 The present invention accommodates a plurality of light source support portions made of inverted V-shaped plate members, a light source provided on an inverted V-shaped outwardly inclined surface of each light source support portion, the light source support portion and the light source. And the plurality of light source support portions are arranged alternately and continuously via a plurality of heat radiating members, and the plurality of light source support portions and the heat radiating member are integrally formed by folding one plate material. The plurality of heat radiating members are in contact with the casing .

前記放熱部材は、前記筐体の底部に当接する。The heat radiating member is in contact with the bottom of the housing.

また、前記光源支持部の一端部に、第２の放熱部材が設けられている Moreover, the 2nd heat radiating member is provided in the one end part of the said light source support part.

また、前記第２の放熱部材は、前記筐体の側壁に当接する。 The second heat radiating member is in contact with the side wall of the housing.

本発明によれば、光源を取り付ける光源支持部を軽量化して、光源の放熱効果を高くできる。また、光源支持部は、板材の折り曲げによって製造できるため、簡単に製造でき、押出材に比べてコストを抑えて製造できる。   According to the present invention, the light source support part to which the light source is attached can be reduced in weight, and the heat radiation effect of the light source can be enhanced. Moreover, since the light source support part can be manufactured by bending a plate material, it can be easily manufactured and can be manufactured at a lower cost than the extruded material.

FIG. 1 is a perspective view showing a lighting apparatus 10 according to an embodiment of the present invention. This lighting fixture 10 is provided with two rows of light source blocks 25 in which a plurality of first light source support portions 11 made of an inverted V-shaped plate material are connected in a row. An LED 13 serving as a light source is provided on the inclined surface 12 of each first light source support portion 11 that faces the inverted V-shaped diagonally upward direction. The two rows of light source blocks 25 are accommodated in the housing 14 so as to face in opposite directions. The housing 14 is provided with a window 21 that emits light from the LED 13.

図２に示すように、各光源ブロック２５の第１光源支持部１１におけるＬＥＤ１３側の傾斜面１２の下端部には、筐体１４の底部１５に当接する板状の第１放熱部材１６が設けられている。また、各光源ブロック２５の第１放熱部材１６がない方の端部には、第１放熱部材１６を介して、くの字型の板状の第２光源支持部１７が設けられている。第２光源支持部１７における第１放熱部材１６と反対側の端部には、筐体１４の側壁１８（図１参照）に当接する第２放熱部材１９が設けられている。   As shown in FIG. 2, a plate-like first heat radiating member 16 that comes into contact with the bottom portion 15 of the housing 14 is provided at the lower end portion of the inclined surface 12 on the LED 13 side in the first light source support portion 11 of each light source block 25. It has been. In addition, at the end of each light source block 25 where the first heat radiating member 16 is not provided, a V-shaped plate-like second light source support portion 17 is provided via the first heat radiating member 16. A second heat radiating member 19 that abuts against the side wall 18 (see FIG. 1) of the housing 14 is provided at the end of the second light source support portion 17 opposite to the first heat radiating member 16.

第２光源支持部１７の外向きの傾斜面２０には、第１光源支持部１１のＬＥＤ１３と同一方向を向くＬＥＤ１３が設けられている。各光源ブロック２５における全てのＬＥＤ１３から放射される光は、筐体１４の窓２１から、それぞれ所定の方向に向かって照射される。   The outwardly inclined surface 20 of the second light source support 17 is provided with an LED 13 that faces the same direction as the LED 13 of the first light source support 11. Light emitted from all the LEDs 13 in each light source block 25 is irradiated from the window 21 of the housing 14 in a predetermined direction.

Therefore, the cost can be reduced as compared with the case where the first light source support portion 11 is formed of a conventional extruded material or the like.

また、第２光源支持部１７は、板材によってくの字型に形成されているため、軽量化できる。   Moreover, since the 2nd light source support part 17 is formed in the dogleg shape by the board | plate material, it can reduce in weight.

また、複数の第１光源支持部１１が、一体的に接続されているため、放熱効果が向上する。   Moreover, since the several 1st light source support part 11 is connected integrally, the thermal radiation effect improves.

更に、第１光源支持部１１の一端に、筐体１４の底部１５に当接する第１放熱部材１６が設けられているため、第１光源支持部１１の放熱効果が向上できる。これにより、ＬＥＤ１３の温度を効果的に低下させることが可能となる。   Furthermore, since the first heat radiation member 16 that contacts the bottom portion 15 of the housing 14 is provided at one end of the first light source support portion 11, the heat radiation effect of the first light source support portion 11 can be improved. Thereby, it becomes possible to reduce the temperature of LED13 effectively.

また、複数の第１光源支持部１１が、第１放熱部材１６を介して一体的に設けられているため、更に放熱効果が向上する。   Moreover, since the several 1st light source support part 11 is integrally provided via the 1st heat radiating member 16, the heat dissipation effect improves further.

更に、第１光源支持部１１の一端に、筐体１４の側壁１８に当接可能なくの字型の第２光源支持部１７が設けられているため、第１光源支持部１１を筐体１４の側壁１８の近傍に配置できる。   Furthermore, since the first light source support 11 is provided with a second light source support 17 in a shape that cannot contact the side wall 18 of the housing 14 at one end of the first light source support 11, the first light source support 11 is attached to the housing 14. It can arrange | position to the side wall 18 vicinity.

本実施形態では、第２光源支持部１７に一体的に第２放熱部材１９が設けられているため、更に放熱効果を向上できる。   In the present embodiment, since the second heat radiating member 19 is provided integrally with the second light source support portion 17, the heat radiation effect can be further improved.
