Description

本発明は、ＬＥＤ電球に関し、特に放熱効果の高い照明用ＬＥＤ電球に関する。  The present invention relates to an LED bulb, and more particularly to an illumination LED bulb with a high heat dissipation effect.

近年、一般家庭でも白熱電球や電球タイプの蛍光ランプが使用されていたが、これに替わり、発光ダイオードを光源とするＬＥＤ電球が普及してきており、例えば下記のような特開２００９−１７０１１４号や特開２０１０−５６０５９号が開発されている。  In recent years, incandescent bulbs and bulb-type fluorescent lamps have been used even in ordinary homes. Instead, LED bulbs using light-emitting diodes as light sources have become widespread. For example, the following JP 2009-170114 A and Japanese Patent Application Laid-Open No. 2010-56059 has been developed.

特開２００９−１７０１１４号公報  JP 2009-170114 A 特開２０１０−５６０５９号公報  JP 2010-56059 A

前記せる特開２００９−１７０１１４号公報及び特開２０１０−５６０５９号公報ではいずれもグローブの下方外側に複数の放熱フィンのみを設けて放熱している。  In both of the above-mentioned JP 2009-170114 A and JP 2010-56059 A, only a plurality of heat dissipating fins are provided outside the globe to radiate heat.

ＬＥＤは、温度上昇に伴い光出力が低下し、寿命も短くなるので、ＬＥＤの温度上昇を抑制することが重要課題である。  Since the light output of the LED decreases as the temperature rises and the life of the LED decreases, it is important to suppress the temperature rise of the LED.

しかしながら、前記せるような従来例の場合は、グローブ内で上昇した温度がＬＥＤチップ１０の近傍で滞留してしまい、このような状態で放熱フィンの放熱効果みでＬＥＤの温度上昇を抑制するには不十分であって、さらなるＬＥＤの放熱性を向上することが望まれている。However, in the case of the conventional example as described above, the temperature increased in the globe stays in the vicinity of the LED chip 10, and in this state, the heat dissipation effect of the heat dissipation fins suppresses the LED temperature increase. Is insufficient, and it is desired to further improve the heat dissipation of the LED.

本発明の放熱効果の高い照明用ＬＥＤ電球では、以下に示すような構成でＬＥＤの温度上昇を抑制するものである。  The lighting LED bulb with high heat dissipation effect of the present invention suppresses an increase in LED temperature with the following configuration.

ガラス球体及び口金によって一体的に封止されたＬＥＤ電球において、筺体支持部材によって、順次積層状態に支持された回路基板、電気感応作動媒体収納筺体、ファン取付け枠及びＬＥＤチップ保持筺体とが、ガラス球体内に封止された構成からなることを特徴とし、電気感応作動媒体収納筺体内の電気感応作動媒体に電圧を印加し、電気感応作動媒体の回転に伴い回転体及び回転軸が回転し、回転軸に連結したファンが回転してガラス球体内の高温で滞留した空気を対流させながら、ガラス球体の下方に取付けた放熱フィンを介して放熱効率を向上させるように構成したことを特徴とし、且つ、ＬＥＤチップ保持筺体内側の放熱フィン兼用ＬＥＤチップ保持体がＬＥＤチップを保持しており、放熱フィン兼用ＬＥＤチップ保持体の間隙を通して通気性が良く、ファン取付け枠も通気性が良く形成されていることを特徴とする放熱効果の高い照明用ＬＥＤ電球を提供する。  In an LED bulb integrally sealed with a glass sphere and a base, a circuit board, an electrically sensitive working medium storage casing, a fan mounting frame, and an LED chip holding casing, which are sequentially supported in a stacked state by a casing support member, are made of glass. It is characterized by comprising a structure sealed in a sphere, a voltage is applied to the electrically sensitive working medium in the electrically sensitive working medium storage housing, and the rotating body and the rotating shaft rotate with the rotation of the electrically sensitive working medium, The fan connected to the rotating shaft rotates and convects the air staying at a high temperature in the glass sphere, and is configured to improve the heat dissipation efficiency through the heat dissipation fin attached below the glass sphere, In addition, the LED chip holding body inside the LED chip holding housing holds the LED chip, and the gap between the heat radiation fin and LED chip holding body is Good ventilation by the fan mounting frame also provides a high illumination LED bulbs heat dissipation effect, characterized in that it is well-formed breathable.

本発明は以上のような構成であるので、ガラス球体内で高温となった気体が滞留することなく、対流しているので、放熱フィンからの放熱効率がよく従来と比較して優れた放熱効果を有する照明用ＬＥＤ電球を提供できるものである。  Since the present invention is configured as described above, the high-temperature gas in the glass sphere convects without stagnation. It is possible to provide an LED light bulb for illumination having the following.

以下、図面に基づいて本発明の放熱効果の高い照明用ＬＥＤ電球について説明する。
図面において、図１は本発明に係る放熱効果の高い照明用ＬＥＤ電球の斜視図であり、図２は本発明の放熱効果の高い照明用ＬＥＤ電球の要部分解断面図である。Hereinafter, the LED light bulb for illumination with high heat dissipation effect of the present invention will be described based on the drawings.
In the drawings, FIG. 1 is a perspective view of a lighting LED bulb with high heat dissipation effect according to the present invention, and FIG. 2 is an exploded cross-sectional view of a main part of the LED light bulb with high heat dissipation effect of the present invention.

ガラス球体１及び口金１１によって一体的に封止された照明用ＬＥＤ電球１００において、筺体支持部材７によって、回路基板５、電気感応作動媒体収納筺体４、ファン取付け枠３及びＬＥＤチップ保持筺体２とが順次積層状態に支持され、ガラス球体１内に封止されている。  In the lighting LED bulb 100 integrally sealed with the glass sphere 1 and the base 11, the circuit board 5, the electrically sensitive working medium storage housing 4, the fan mounting frame 3, and the LED chip holding housing 2 are formed by the housing support member 7. Are sequentially supported in a laminated state and sealed in the glass sphere 1.

電気感応作動媒体収納筺体４内の電気感応作動媒体４０に電圧を印加し、電気感応作動媒体４０が回転を始める。次いでこの回転に伴い回転体４２，及び回転軸４３が回転し、回転軸４３に連結したファン３１が回転してガラス球体１内の高温で滞留した空気を対流させながら、ガラス球体１の下方に取付けた放熱フィン６を介して放熱効率を向上させるようにしてある。  A voltage is applied to the electrically sensitive working medium 40 in the electrically sensitive working medium housing 4 and the electrically sensitive working medium 40 starts to rotate. Then, the rotating body 42 and the rotating shaft 43 are rotated along with this rotation, and the fan 31 connected to the rotating shaft 43 is rotated to convect the air staying at a high temperature in the glass sphere 1, and below the glass sphere 1. The heat radiation efficiency is improved through the attached heat radiation fins 6.

ＬＥＤチップ保持筺体２の内側の放熱フィン兼用ＬＥＤチップ保持体２１がＬＥＤチップ１０を保持しており、放熱フィン兼用ＬＥＤチップ保持体２１の間隙を通して通気性が良く、ファン取付け枠も通気性が良く形成されている。  The LED chip holding body 21 serving as a radiation fin inside the LED chip holding housing 2 holds the LED chip 10, and the air permeability is good through the gap between the heat radiation fin and LED chip holding body 21, and the fan mounting frame is also air permeability. Is formed.

従って、口金１１がソケット（図示せず）に螺着された時から、ファン３１は回転を始めており、ＬＥＤチップ保持筺体２を通過した空気は図中矢印で示すように対流が生じてガラス球体１の中で撹拌される。  Accordingly, the fan 31 has started to rotate since the base 11 is screwed into the socket (not shown), and the air that has passed through the LED chip holding housing 2 is convected as indicated by the arrows in the figure, so that the glass sphere Stir in 1.

電源導線８、９より回路基板５を介してＬＥＤチップ１０へ給電されると共に電気感応作動媒体４０へ給電され、上記の対流が生じ、放熱効果を得るものである。  Power is supplied to the LED chip 10 from the power supply wires 8 and 9 via the circuit board 5 and also supplied to the electrically sensitive working medium 40, and the convection is generated to obtain a heat dissipation effect.

電気感応作動媒体４０の移動流原理は電極５１の配置によって生じるものであり、電気感応作動媒体収納筺体４内の電気感応作動媒体４０は電圧を印加することによって電界間を移動する電界共役流体（Ｅｌｅｃｔｒｏ−Ｃｏｎｊｕｇａｔｅ Ｆｌｕｉｄ）の原理を応用したものである。    The principle of the moving flow of the electrosensitive working medium 40 is generated by the arrangement of the electrodes 51, and the electrosensitive working medium 40 in the electrosensitive working medium housing 4 is applied with an electric field conjugate fluid (moving between electric fields by applying a voltage). This is an application of the principle of Electro-Conjugate Fluid).

本発明の放熱効果の高い照明用ＬＥＤ電球によれば、従来と比較して優れた放熱効果を有し、長寿命のＬＥＤ電球を提供することができる。  According to the lighting LED bulb with high heat dissipation effect of the present invention, it is possible to provide a long-life LED bulb having a heat dissipation effect superior to the conventional one.
