Description

本発明は発光ダイオード(ＬＥＤ)を利用した半導体発光による照明装置に関し、特に、店舗や各種展示空間で使用する小型のスポットライトに関する。     The present invention relates to a lighting device using semiconductor light emission using a light emitting diode (LED), and more particularly to a small spotlight used in a store or various exhibition spaces.

従来、スポットライトの光源としては、電球が多く用いられている。しかし、電球は、輝度は高いが、電力消費量や発熱量が多いため、これらを低減させる光源がもとめられている。   Conventionally, a light bulb is often used as a light source of a spotlight. However, although the light bulb has high brightness, it consumes a large amount of power and generates heat, and therefore a light source that reduces them is sought.

近年、高輝度の発光ダイオードが提供されるようになり、これを用いたライトも実用化されている。   In recent years, light emitting diodes with high luminance have been provided, and lights using the same have been put into practical use.

例えば、特許文献１には、砲弾型の第１レンズ内に発光ダイオードを組み込み、この第１ンズの前側に拡散板を配置し、この拡散板の前方に第２レンズを配置したスポットライトが、また、特許文献２には、発光ダイオードを保持するとともに先部にレンズの外周基部を支持した内筒部にレンズを固定する外筒部を螺合して構成したスポットライトがそれぞれ開示してある。
特開２０００-１８８００２号公報 特開２００４−１５８２７６号公報 For example, Patent Document 1 discloses a spotlight in which a light emitting diode is incorporated in a bullet-type first lens, a diffusion plate is arranged on the front side of the first lens, and a second lens is arranged in front of the diffusion plate. Further, Patent Document 2 discloses spotlights each configured by screwing an outer cylinder portion for fixing a lens to an inner cylinder portion that holds a light emitting diode and supports an outer peripheral base portion of the lens at a front portion. .

しかしながら、いずれのスポットライトも、発光ダイオードをケーシング内に収納して、非開放型に構成してあることから、発光ダイオードからの発熱による熱がケーシング内にこもりやすく、光源装置として熱を持ちやすいという問題がある。   However, each spotlight has a light emitting diode housed in a casing and is configured as a non-open type. Therefore, heat due to heat generated from the light emitting diode is easily trapped in the casing, and heat is easily generated as a light source device. There is a problem.

このような点に着目して、本発明は、十分な照度を持つものでありながら、発光ダイオードの発熱を効率よく放散することのできるスポットライトを提供することを目的とする。   In consideration of such a point, an object of the present invention is to provide a spotlight that can efficiently dissipate heat generated from a light-emitting diode while having sufficient illuminance.

上述の目的を達成するために本発明は、基板に白色発光ダイオードを設置し、この基板の前方にスペーサを介してレンズ固定板を配置し、前記白色発光ダイオードに対応させて配置したレンズをこのレンズ固定板に挿入固定するとともに、レンズ固定板の前側に前カバーを配設してレンズ固定板に連結固定し、基板を放熱用ブラケットを介してランプシェード内に配設固定することにより、基板、レンズ固定板、前カバーをランプシェード内に位置させるようにしたことを特徴としている。   In order to achieve the above object, the present invention provides a white light emitting diode on a substrate, a lens fixing plate disposed in front of the substrate via a spacer, and a lens disposed corresponding to the white light emitting diode. By inserting and fixing to the lens fixing plate, arranging a front cover on the front side of the lens fixing plate, connecting and fixing to the lens fixing plate, and arranging and fixing the substrate in the lamp shade via the heat radiating bracket, The lens fixing plate and the front cover are located in the lamp shade.

本発明では、発光ダイオードを設置している基板を放熱用ブラケットを介してランプシェード内に配設固定するとともに、基板の前方にスペーサを介してレンズ固定板を配置し、レンズ固定板の前面に前カバーを配置しているので、発光ダイオードで発生した熱は、ランプシェードや前カバー部分を含む広い面積から放熱されることになる。この結果、発光ダイオードの熱による寿命低下を極力防止することができる。   In the present invention, the substrate on which the light emitting diode is installed is disposed and fixed in the lamp shade through the heat dissipation bracket, and the lens fixing plate is disposed in front of the substrate through the spacer, and is disposed on the front surface of the lens fixing plate. Since the front cover is arranged, the heat generated by the light emitting diode is radiated from a wide area including the lamp shade and the front cover portion. As a result, it is possible to prevent the life of the light emitting diode from being reduced due to heat.
