Description

本発明は、ＬＥＤ照明灯の構造に利用される。The present invention is used for the structure of LED lighting.

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、ＬＥＤを保護のため透明なアクリルやガラス管内などに密封する場合、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。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. In particular, when an LED that requires high brightness is sealed in a transparent acrylic or glass tube for protection, the LED must be cooled in a sealed environment.

本発明は、柱状のガラス管などの透明管内に密封された高輝度ＬＥＤを使用したＬＥＤ照明灯において、発生する熱をＬＥＤを取り付けたアルミニュームなどの押し出し材の押し出し方向末端に設けた柱状の押し出し材からなるヒートシンクに伝導させ、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。The present invention relates to an LED illuminating lamp using a high-intensity LED sealed in a transparent tube such as a columnar glass tube. The generated heat is provided at the end of the extrusion direction of an extrusion material such as an aluminum to which the LED is attached. Conduction to a heat sink made of extruded material and cooling to prevent destruction and deterioration of the LED.

本発明は、ガラス管などの透明な中空部に設けた押し出し材からなるＬＥＤ取付台に高輝度ＬＥＤ構成することにより、前記ＬＥＤからの熱を前記ＬＥＤ取付台末端に構成させた複数のフィンを構成したヒートシンクに前記ＬＥＤ取付台に設けた小突起を構成した接続部を前記ヒートシンクに構成した対応する接続穴に挿入して圧力により前記ＬＥＤ取付台と前記ヒートシンクを接続することにて伝導させ前記ヒートシンクに構成した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。According to the present invention, a plurality of fins in which heat from the LED is configured at the end of the LED mounting base by configuring the LED mounting base made of an extrusion material provided in a transparent hollow portion such as a glass tube as a high brightness LED. Inserting a connecting portion that configures a small protrusion provided on the LED mounting base into the configured heat sink into a corresponding connection hole configured on the heat sink, and conducting by connecting the LED mounting base and the heat sink by pressure. It cools by releasing to the outside air from the fin comprised in the heat sink, and protects LED from deterioration and destruction by heat.

密封された環境においても、ＬＥＤから発せられる熱を、外気に放熱できるので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 to the outside air, 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.

The tapped screw screw hole (2) in the main body connecting portion (5) configured in the opposite direction is for assembling the LED mounting base (A) to the LED lighting body (the tapped screw screw hole ( The reason why 2) is not a perfect circle is due to the technique in the case of manufacturing with an extruded material, and the connection part (4) with the heat sink constructed on the left and right of the LED mounting base (A) is a small protrusion on its surface. The part (3) is a connection screw hole when connecting the heat sink and the mounting base (A). FIG. 2A radiates the heat from the LED mounting base (A). Multiple fins (8) for The heat sink (B) made from the extruded material formed, (6) is the LED mounting base connection part, and the LED mounting base connection hole of (7) is connected to the heat sink (B) of the LED mounting base (A). The connecting part (4) is inserted.
