Description

本発明は、３６０度方向に投光できるＬＥＤ照明灯。The present invention is an LED illuminating lamp capable of projecting in a 360-degree direction.

技術背景Technical background

ＬＥＤ照明に使われる、ＬＥＤは、発光時における熱により性能の劣化などがおきるため、生じる熱の放熱を行う放熱器（以下ヒートシンクと呼ぶ）が必要となる。特に高輝度を必要とする、野外での使用においては、防水仕様などを施さなくてはならないので、ＬＥＤをガラス管内などに密封する場合がありその際の密封された環境におけるＬＥＤ冷却が必要となってくる。また、イカ釣り漁船などにて使用する集魚灯などは、３６０度を投光する、防水仕様の高輝度照明が必要であり、これをＬＥＤ照明に置き換える場合、ＬＥＤから発せられる熱は高温になり、冷却対策が必要になる。Since the LED used for LED illumination deteriorates in performance due to heat generated during light emission, a heat radiator (hereinafter referred to as a heat sink) is required to dissipate the generated heat. Especially in outdoor use that requires high brightness, waterproof specifications must be applied, so the LED may be sealed in a glass tube or the like, and LED cooling in a sealed environment at that time is required. It becomes. In addition, the fishing lights used on squid fishing fishing boats, etc. require 360-degree high-intensity lighting that is waterproof, and when this is replaced with LED lighting, the heat emitted from the LEDs becomes high. Cooling measures are necessary.

本発明は、ガラス管内に密封された高輝度ＬＥＤを使用した３６０度を投光を可能にするＬＥＤ照明灯において、発生する熱を柱状の押し出し材からなるヒートシンクを使用して、冷却することにより、ＬＥＤの破壊及び劣化を防ぐものである。According to the present invention, in an LED illuminating lamp capable of projecting 360 degrees using a high-intensity LED sealed in a glass tube, the generated heat is cooled by using a heat sink made of a columnar extruded material. This prevents the destruction and deterioration of the LED.

本発明は、内部に複数のフィンを構成した柱状ヒートシンクの外側に高輝度ＬＥＤ構成することにより、前記ＬＥＤからの熱を前記複数のフィンに伝導しフィンから外気に放出することにより冷却し、熱による劣化及び破壊からＬＥＤを守る。In the present invention, a high-intensity LED is formed outside a columnar heat sink having a plurality of fins inside, and heat is transmitted by conducting heat from the LEDs to the plurality of fins and releasing it from the fins to the outside air. Protects LEDs from degradation and destruction by

密封された環境においても、ＬＥＤから発せられる熱を、放熱できるのでＬＥＤの劣化及び破壊を防ぐことができる。Even in a sealed environment, heat generated from the LED can be dissipated, so that deterioration and destruction of the LED can be prevented.

以下、本発明の実施の形態を図１から図２を使用して説明する。Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図１の図（１ａ）は、従来の方法でのＬＥＤを３６０度方向に投光するための、高輝度ＬＥＤを使用した、ＬＥＤ照明灯である、高輝度用ＬＥＤ（１）は、円柱形状のアクリルまたはガラスなどでできた、円柱管（４）の中のヒートパイプ（３）の周囲に３６０度方向に投光できるように前記ヒートパイプ（３）の周囲に取り付けられている、ＬＥＤ（１）から発せられる熱は、前記ヒートパイプ（３）に熱伝導される。
円柱管（４）内においては、ＬＥＤ（１）生した熱が、熱伝導できるより温度の低い場所がない場合は、前記ヒートパイプ（３）の温度を上昇させその熱で管内部の温度上昇させた後、前記円柱管（４）表面から外部に放熱という形になるが、空気の熱伝導率は低いので、ヒートパイプ（３）の温度は、時間がたつにつれてＬＥＤ（１）温度まで上昇する。
これらのヒートパイプ（３）の温度上昇を防ぐため、前記ヒートパイプ（３）の両端にヒートシンク（２）を構成することにより、ヒートパイプ（３）熱伝導された熱を前記ヒートシンク（２）にて外気に放熱する仕組みである。図（２ａ）は、図（１ａ）の斜視図であり、図（３ａ）は、図（２ａ）におけるＡ−Ａ断面図である、図（３ａ）におけるヒートパイプ（３）内部の矢印は、ヒートパイプ（３）内の熱の流れを表している。この方法は、ＬＥＤ（１）から発生する熱は、長い距離をヒートパイプ（３）により熱伝導されるという工程を取るということと、熱伝導にてヒートパイプ（３）から伝導された熱はヒートシンク（２）とヒートパイプ（３）の接続方法などにより、接続部の熱抵抗値の変化で熱伝導が左右されるので、放熱能力が低減する場合があるなどの問題があった。The figure (1a) of FIG. 1 is an LED illuminating lamp using a high-intensity LED for projecting the LED in the conventional method in the direction of 360 degrees. The high-intensity LED (1) is a cylindrical shape. LED (attached to the periphery of the heat pipe (3) so that light can be projected in a 360 degree direction around the heat pipe (3) in the cylindrical tube (4) made of acrylic or glass of The heat generated from 1) is conducted to the heat pipe (3).
In the cylindrical tube (4), when there is no place where the heat generated by the LED (1) is lower than the heat can be conducted, the temperature of the heat pipe (3) is increased and the temperature inside the tube is increased by the heat. After heat treatment, heat is released from the surface of the cylindrical tube (4) to the outside, but since the thermal conductivity of air is low, the temperature of the heat pipe (3) rises to the LED (1) temperature over time. To do.
In order to prevent the temperature of these heat pipes (3) from rising, a heat sink (2) is formed at both ends of the heat pipe (3), so that heat conducted by the heat pipe (3) is transferred to the heat sink (2). It is a mechanism to dissipate heat to the outside air. Fig. (2a) is a perspective view of Fig. (1a), Fig. (3a) is a cross-sectional view taken along the line AA in Fig. (2a), and the arrow inside the heat pipe (3) in Fig. (3a) is The flow of heat in the heat pipe (3) is shown. In this method, the heat generated from the LED (1) takes a process in which a long distance is conducted by the heat pipe (3), and the heat conducted from the heat pipe (3) by heat conduction is Depending on the connection method of the heat sink (2) and the heat pipe (3), etc., the heat conduction is affected by the change in the thermal resistance value of the connection portion, and thus there is a problem that the heat dissipation capability may be reduced.

図２は本発明による、ＬＥＤ照明灯である、アルミニュームの中空押し出し材からなる複数の放熱用フィン（７）を内部に構成した、円柱状のヒートシンク（６）と反対面のヒートシンクベース（５）にＬＥＤ（１０）を構成しかつ前記押し出し材の押し出し方向の両端にエンドキャップ（８）を構成し、前記ヒートシンク（６）周囲をアクリルまたはガラスの円柱管（９）で囲むことによりＬＥＤ（１０）を保護している。
図（１ｂ）は本発明による、ＬＥＤ照明灯の正面図であり図（２ｂ）は、その斜視図である、ＬＥＤ（１０）から生じた熱はヒートシンクベース（５）から反対側に構成されたフィン（７）に熱伝導される、フィン（７）は外気と接しているので、熱はフィン（７）から外気へ熱伝達されることにより放熱される。このことにより、ＬＥＤ（１０）から発生した熱は、長い距離の熱伝導をせずに外気に放出できるので、放熱効率が良くなる。
また、本発明には、ヒートシンク（６）、エンドキャップ（８）、ガラス円柱管（９）という単純な構造で３６０度を投光できる、高輝度ＬＥＤの冷却を行える。
図（３ｂ）は、図（１ｂ）におけるＢ−Ｂ切断面である。FIG. 2 shows a heat sink base (5) opposite to a columnar heat sink (6), which is an LED illumination lamp according to the present invention and has a plurality of heat radiation fins (7) made of a hollow extruded material of aluminum. ) And an end cap (8) at both ends in the extrusion direction of the extrusion material, and the heat sink (6) is surrounded by an acrylic or glass cylindrical tube (9) to form the LED ( 10) is protected.
FIG. 1 (b) is a front view of an LED illuminating lamp according to the present invention, and FIG. 2 (b) is a perspective view thereof. The heat generated from the LED (10) is configured on the opposite side from the heat sink base (5). Since the fin (7) that is thermally conducted to the fin (7) is in contact with the outside air, the heat is dissipated by being transferred from the fin (7) to the outside air. Thus, the heat generated from the LED (10) can be released to the outside air without conducting heat for a long distance, so that the heat dissipation efficiency is improved.
Further, the present invention can cool a high-brightness LED that can project 360 degrees with a simple structure of a heat sink (6), an end cap (8), and a glass cylindrical tube (9).
The figure (3b) is a BB cut surface in the figure (1b).
