Abstract
本発明は、ヒートシンクに取り付けられた1又はそれ以上のLEDを有するLED光源から放射された光をリサイクルする装置である。本装置は、出力端部より小さい入力端部をもつ、矩形または円形のテーパー状光管が含まれる。LEDは、入力端部に接続されている。出力端部は、反射内面をもつ中空トンネルに接続され、中空トンネルの他端は、中空トンネルの内部表面に向けられた鏡によって覆われている。鏡は、中央部に設けられた出力アパーチャと、LEDから放射された光を出力アパーチャに導く反射内面を有する。鏡は、LEDから放射された光の一部であって出力アパーチャが存在しない部分の光を反射し、それによって、光りをリサイクルし、出力アパーチャを通して放射される光の輝度が向上する。The present invention is an apparatus for recycling light emitted from an LED light source having one or more LEDs attached to a heat sink. The device includes a rectangular or circular tapered light tube with an input end that is smaller than the output end. The LED is connected to the input end. The output end is connected to a hollow tunnel having a reflective inner surface, and the other end of the hollow tunnel is covered by a mirror directed to the inner surface of the hollow tunnel. The mirror has an output aperture provided in the center and a reflective inner surface that guides light emitted from the LED to the output aperture. The mirror reflects a portion of the light emitted from the LED where there is no output aperture, thereby recycling the light and improving the brightness of the light emitted through the output aperture.

発明者：ケネス・リー Inventor: Kenneth Lee
特許請求の範囲：
LEDの輝度を向上させるために、LEDチップに戻る光のリサイクリル方法を用いる。様々なレベルの費用および困難さを伴う多数の方法が、用いられてきた。本発明では、簡潔で対費用効果の高いリサイクル方法として、固体で中空の光管の組み合わせが用いられる。
Claims:
In order to improve the brightness of the LED, a light recycling method returning to the LED chip is used. A number of methods with varying levels of cost and difficulty have been used. In the present invention, a solid, hollow light tube combination is used as a simple and cost-effective recycling method.
図1は、本発明の実施形態を示している。それは、ヒートシンクに搭載された1つ以上のLEDからなる光源を含んでいる。光源の出力は、より大きいエリアを有する出力端部をもつテーパー状の光管（TLP）の入力端部に接続される。TLPの断面は、正方形、長方形、円、またはその他の形とすることができる。TLPは、小さいエリアからの光を、入力部では大きいエリアに向けて大きい角度に変形させ、出力部では小さい角度に変形させる。TLPの出力面は平面であってもよいが、より効果的な変形のために、TLPの出力面は凸面状とされる。TLPの出力部は、反射する内壁をもつ中空の光管に接続される。中空の光管は、光を出力端部に向けて誘導する。出力端部では、リサイクルのために、光の一部を中空の光管、TLPおよび光源に戻すために反射させる鏡が使われる。反射されなかった光は、システムの出力部であるアパーチャを通って出る。出力アパーチャは、正方形、長方形、円形などとすることができる。反射されて光源に戻された光は、放射された光と一緒に出力部の方に向け直され、システムの輝度が向上する。 FIG. 1 shows an embodiment of the present invention. It contains a light source consisting of one or more LEDs mounted on a heat sink. The output of the light source is connected to the input end of a tapered light tube (TLP) with an output end having a larger area. The cross section of the TLP can be square, rectangular, circle, or other shape. The TLP transforms light from a small area into a large angle toward a large area at the input unit, and transforms the light into a small angle at the output unit. The output surface of the TLP may be a flat surface, but the output surface of the TLP is convex for more effective deformation. The output of the TLP is connected to a hollow light tube with a reflecting inner wall. The hollow light tube guides light toward the output end. At the output end, a mirror that reflects part of the light back to the hollow light tube, TLP and light source is used for recycling. Unreflected light exits through an aperture that is the output of the system. The output aperture can be square, rectangular, circular, etc. The light reflected back to the light source is redirected to the output along with the emitted light, improving the brightness of the system.
図2aは、光結合システムに適用される本発明の実施形態を示している。本システムは、図 1に示すような2又はそれ以上の光リサイクルシステムモジュール（RLSM）を含む。各RLSMは、互いに異なる色のLEDから構成されている。図2aに示すように、それは3つのRLSMから構成されており、1つは赤色、1つは緑色、もう1つは青色である。これらは、3原色であり、組み合わされるとカラーディスプレーを構成する。４つのRLSM、例えば赤色、緑色、青色、そして黄色を使って４色システムを構成することもできる。図2aに示すように、RLSMからの3つの色すべての出力が最小限の損失で済むようにするために、3つのRLSMの出力部は、適切な色を伝達し反射する2つの対角なカラーフィルターから構成されるＸキューブを使って組み合わされる。図2bは、反射面とアパーチャが用いられたＸキューブを示している。反射面とアパーチャは、Ｘキューブの一部として作られても構わないし、RLSMを備えた中空の光管の一部であっても構わない。 FIG. 2a shows an embodiment of the invention applied to an optical coupling system. The system includes two or more light recycling system modules (RLSM) as shown in FIG. Each RLSM is composed of LEDs of different colors. As shown in FIG. 2a, it is composed of three RLSMs, one red, one green, and one blue. These are the three primary colors, and when combined, form a color display. A four-color system can also be constructed using four RLSMs, such as red, green, blue, and yellow. As shown in Figure 2a, to ensure that the output of all three colors from the RLSM requires minimal loss, the three RLSM outputs are two diagonals that transmit and reflect the appropriate color. They are combined using an X cube composed of color filters. FIG. 2b shows an X-cube using a reflective surface and an aperture. The reflective surface and the aperture may be made as part of the X-cube, or may be part of a hollow light tube with RLSM.
図3aは、一緒に組み立てられた2又はそれ以上のRLSMによって、リサイクルとともに合成された出力を作り出す実施形態を示している。図 3aに示されるように、それは、長方形のTLPを備えた4つのRLSMから成る2 x 2のシステムであり、図3bに示されるような端面となる。4つの独立した中空の光管を使用することができる。実用的な実装例では、出力部には、1つのアパーチャとともに1つの中空の光管が使用される。リサイクルの過程では、1つの光管からの光のわずかな部分が隣接した光管に反射されることがあるが、この光は隣接したLEDによってリサイクルされるので問題ない。 FIG. 3a shows an embodiment in which two or more RLSMs assembled together produce a combined output with recycling. As shown in FIG. 3a, it is a 2 × 2 system consisting of four RLSMs with a rectangular TLP, resulting in an end face as shown in FIG. 3b. Four independent hollow light tubes can be used. In a practical implementation example, one hollow light tube is used together with one aperture for the output section. In the recycling process, a small part of the light from one light tube may be reflected by the adjacent light tube, but this light is recycled by the adjacent LED, so there is no problem.
TLPは、ガラスまたはプラスチックによって作られることが可能である。それらは、磨かれ、または形成されることができる。端面にARコーティングを追加することができる。 TLP can be made of glass or plastic. They can be polished or formed. AR coating can be added to the end face.
中空の光管は、内側に反射コーティングを施されたガラス、プラスチック、または金属で作られることが可能である。 The hollow light tube can be made of glass, plastic, or metal with a reflective coating on the inside.
アパーチャを持つ出力鏡は、ガラス、プラスチック、または金属で作られることが可能である。 An output mirror with an aperture can be made of glass, plastic, or metal.
テーパー状の光管は、用途の要求に適合するように設計され、光を大きい角度から小さい角度に変換する。 Tapered light tubes are designed to meet application requirements and convert light from a large angle to a small angle.
それは、RLSMからの出力がコリメートされ、またはレンズによって発散が変更されることによって、フラッシュライト、サーチライト、またはスポットライトの用途に使用できる。 It can be used for flashlight, searchlight or spotlight applications by collimating the output from the RLSM or changing the divergence by the lens.
図2aに示すように、Ｘキューブによって組み合わされた出力は、プロジェクター、エンターテイメントの照明システム、およびスポットライトに使用できる。 As shown in FIG. 2a, the combined output by the X-cube can be used for projectors, entertainment lighting systems, and spotlights.
