Description
本発明は、特にヒートパイプを用いることにより、優れた放熱効果を提供する発光ダイオードダウンライトに関するものである。 The present invention relates to a light-emitting diode downlight that provides an excellent heat dissipation effect, particularly by using a heat pipe.
図５及び図６に示すように、例えば後記特許文献１に類似した従来の発光ダイオードダウンライトは、金属シャフト（９１）と、該金属シャフト（９１）の先端に設けられる発光ダイオード（９２）と、該金属シャフト（９１）の外周壁における該金属シャフト（９１）の末端近傍に設けられると共に、径方向に向かって延出する複数の放熱プレート（９３）と、該金属シャフト（９１）と発光ダイオード（９２）と放熱プレート（９３）とを収容するバルブ（９５）と、該バルブ（９５）を封止すると共に、該金属シャフト（９１）の末端に固設されるカバー（９６）とを有するものである。 As shown in FIGS. 5 and 6, for example, a conventional light emitting diode downlight similar to Patent Document 1 described below includes a metal shaft (91) and a light emitting diode (92) provided at the tip of the metal shaft (91). A plurality of heat dissipating plates (93) provided in the vicinity of the end of the metal shaft (91) on the outer peripheral wall of the metal shaft (91) and extending in the radial direction, and the metal shaft (91) emit light A valve (95) that houses the diode (92) and the heat radiating plate (93), and a cover (96) that seals the valve (95) and is fixed to the end of the metal shaft (91). It is what you have.
尚、前記従来の発光ダイオードダウンライトは、前記発光ダイオード（９２）と電源とを電気接続させ、該発光ダイオード（９２）に電力供給すれば、照明効果を提供することはできるが、作動中に、該発光ダイオード（９２）から熱量が発生するので、前記金属シャフト（９１）及び放熱プレート（９３）により、発光ダイオード（９２）から発生した熱を放熱する必要がある。 The conventional light emitting diode downlight can provide a lighting effect by electrically connecting the light emitting diode (92) and a power source and supplying power to the light emitting diode (92). Since the amount of heat is generated from the light emitting diode (92), it is necessary to radiate the heat generated from the light emitting diode (92) by the metal shaft (91) and the heat radiating plate (93).
上述したように、前記従来の発光ダイオードダウンライトは、金属シャフトが理想的な熱伝導効果を発揮することができないので、非常に限られた放熱効果しか提供することができず、例えば、特に大出力の発光ダイオードまたは複数の発光ダイオードを該金属シャフトの先端に設けた構成の場合、発生した大量の熱を放熱しきれないので、発光ダイオード（９２）を破損または故障させてしまう恐れがあった。 As described above, the conventional light-emitting diode downlight can provide only a very limited heat dissipation effect because the metal shaft cannot exhibit an ideal heat conduction effect. In the case where the output light emitting diode or the plurality of light emitting diodes are provided at the tip of the metal shaft, a large amount of generated heat cannot be dissipated, which may cause damage or failure of the light emitting diode (92). .
そこで、案出されたのが本発明であって、大出力の発光ダイオードや複数のダイオードに利用できる、放熱効果に優れた発光ダイオードダウンライトを提供することを目的としている。 Accordingly, the present invention has been devised and an object of the present invention is to provide a light-emitting diode downlight that can be used for a high-power light-emitting diode or a plurality of diodes and has an excellent heat dissipation effect.
