Description
本発明は、複数のＬＥＤを配置するＬＥＤ電球における配置構造に関するものであり、特に自動車用のウエッジバルブや、電機機器のバックライト、照明ランプなどの用途に適するものである。 The present invention relates to an arrangement structure in an LED bulb in which a plurality of LEDs are arranged, and is particularly suitable for applications such as automobile wedge bulbs, backlights of electrical equipment, and illumination lamps.
従来の複数のＬＥＤを使用したＬＥＤ電球の配置構造においては、図５に示す通り、後部ＬＥＤ２ｂの前方に前部ＬＥＤ２ａを重ねて配置した、ＬＥＤの配置構造が知られており、この従来の、ＬＥＤの配置構造においては、前記後部ＬＥＤ２ｂから発せられた光が、前記前部ＬＥＤ２ａの基部によって遮られる事を防止し、光を有効に利用する為に、前記前部ＬＥＤ２ａの基部の裏面に、光反射手段３を設け、前記光反射手段３によって反射された後部ＬＥＤ２ｂの光は、自動車に予め配置されたリフレクターにより前方に照射される構成となっている。 In the arrangement structure of the conventional LED bulb using a plurality of LEDs, as shown in FIG. 5, the LED arrangement structure in which the front LED 2a is arranged in front of the rear LED 2b is known. In the LED arrangement structure, the light emitted from the rear LED 2b is prevented from being blocked by the base of the front LED 2a, and in order to effectively use the light, on the back surface of the base of the front LED 2a, The light reflecting means 3 is provided, and the light of the rear LED 2b reflected by the light reflecting means 3 is irradiated forward by a reflector arranged in advance in the automobile.
この配置構造においては、砲弾型等のリード部４を有するＬＥＤにのみ適用可能であり、ＬＥＤ自体のサイズが大きいため、自動車のウエッジバルブに使用する場合には幅方向に複数のＬＥＤを配置する事が困難であり、又、後方ＬＥＤの光は、リフレクターにより、広い角度に拡散されるため、前方の照射対象に対しては明るさが十分では無かった。
近年においては、定められた空間内において、複数のＬＥＤを基板に効率よく配置する構造が求められており、具体的には、自動車のウエッジバルブに使用する場合は、電球収納部の幅方向の投影面積が小さく、上記従来技術で使用されている砲弾型ＬＥＤにおいては幅方向に複数のＬＥＤを配置する事が困難であり、そのため小型であるチップＬＥＤを使用した場合においても基盤上に３個のＬＥＤを配置する事が限界であり、光量が十分ではなく、更なる改善が望まれていた。 In recent years, there has been a demand for a structure in which a plurality of LEDs are efficiently arranged on a substrate in a defined space. Specifically, when used in a wedge valve of an automobile, the structure in the width direction of the light bulb housing portion is required. Since the projected area is small and it is difficult to arrange a plurality of LEDs in the width direction in the bullet type LED used in the above-mentioned conventional technology, even when a small chip LED is used, there are three on the base. It is the limit to arrange the LED, and the light quantity is not sufficient, and further improvement has been desired.
本発明は、上記のような欠点を除くようにしたものである。 The present invention eliminates the above-mentioned drawbacks.
本発明のＬＥＤの配置構造は、複数のＬＥＤを固定し電気的に接続する基板と、前記基板の表面上に複数の第１のＬＥＤを配置したＬＥＤ電球において、更に前記基板が貫通孔を有し、前記貫通孔内に少なくとも一部が埋設され、天面の位置が前記基板の表面から突出しない位置で前記基板に固定される第２のＬＥＤを有し、前記第２のＬＥＤは発光部の周囲に非発光部が形成され、前記第２のＬＥＤの非発光部の一部が前記第１のＬＥＤの底面と部分的に重なる事を特徴とする。
The LED arrangement structure of the present invention is a substrate in which a plurality of LEDs are fixed and electrically connected, and an LED bulb in which a plurality of first LEDs are arranged on the surface of the substrate, and the substrate further has a through hole. and, the through at least partially embedded in the hole, it has a second LED which is secured to the substrate at a position where the position of the top surface does not protrude from the surface of the substrate, the second LED light-emitting unit non-light emitting portion is formed around the part of the non-light emitting portion of the second LED is characterized in the first LED bottom and partially heavy Do that thing.
更に前記ＬＥＤはチップＬＥＤであり、前記第２のＬＥＤの天面における非発光部の１部が、前記第１のＬＥＤの底面と部分的に重なるようにすると良い。 Furthermore, the LED is a chip LED, and a part of the non-light emitting portion on the top surface of the second LED may be partially overlapped with the bottom surface of the first LED.
又、前記第１のＬＥＤが３個のチップＬＥＤから構成され、前記第１のＬＥＤの固定位置は、夫々前記第２のＬＥＤの光軸からほぼ等しい距離で且つ、前記第１のＬＥＤの底面が前記第２のＬＥＤの発光部を覆わない位置に配置すると良い。 The first LED is composed of three chip LEDs, and the fixing position of the first LED is approximately equal to the optical axis of the second LED, and the bottom surface of the first LED. However, it is good to arrange | position in the position which does not cover the light emission part of said 2nd LED.
上記のように、本発明においては、基板の表面上に配置された複数の第１のＬＥＤに加えて、前記貫通孔内に少なくとも一部が埋設された第２のＬＥＤが発光に寄与するため、非常に狭い面積内に効率良くＬＥＤを配置できるので、一層の光量を得られるものとなっている。 As described above, in the present invention, in addition to the plurality of first LEDs arranged on the surface of the substrate, the second LED at least partially embedded in the through hole contributes to light emission. Since LEDs can be efficiently arranged in a very small area, a further light quantity can be obtained.
又、本発明のＬＥＤにチップＬＥＤを使用した場合は、基板の中央に設けた孔に第２のＬＥＤを埋設し、更に基板の表面上に、前記第２のＬＥＤの光軸からほぼ等しい距離で且つ、前記第２のＬＥＤの非発光部の１部が前記第１のＬＥＤの底面と部分的に重なり、前記第２のＬＥＤの発光部を覆わない位置に、３個の第１のＬＥＤを配置した場合、ウエッジバルブとして使用出来る効果がある。 Further, when a chip LED is used for the LED of the present invention, the second LED is embedded in a hole provided in the center of the substrate, and the distance from the optical axis of the second LED is substantially equal on the surface of the substrate. In addition, three first LEDs are arranged at a position where a part of the non-light emitting portion of the second LED partially overlaps the bottom surface of the first LED and does not cover the light emitting portion of the second LED. Is effective for use as a wedge valve.
本発明の利用により、自動車のウエッジバルブに使用する出来るチップＬＥＤの数量を従来の３個から４個に増加することが出来るため、従来と比較して、より明るい自動車のウエッジバルブを製造することが出来る。 By utilizing the present invention, the number of chip LEDs that can be used in a wedge valve of an automobile can be increased from three to four, so that a brighter automobile wedge valve can be manufactured compared to the conventional one. I can do it.
