発光ダイオードを利用した照明電球は、同等の光量を得るための消費電力が少なく、発熱も少ないという利点を有していることから、種々の形態のものが開発されている。そして、商用電圧用の一般的な電球用口金を使用する発光ダイオードを組み込んだ電球として、従来、電球用口金の内部に複数の砲弾型発光ダイオードを並べた基板と、電圧・電流調整回路等を組み込んだ基板とを配置し、電球口金の開口にボール状の樹脂カバーを装着して構成したものが提案されている。(特許文献１)
特開２００３‐１５１３０６公報 Lighting bulbs using light-emitting diodes have the advantages of low power consumption and low heat generation for obtaining an equivalent amount of light, and various forms have been developed. And as a light bulb incorporating a light emitting diode using a general light bulb base for commercial voltage, conventionally, a substrate in which a plurality of bullet light emitting diodes are arranged inside the light bulb base, a voltage / current adjustment circuit, etc. There has been proposed a structure in which a built-in substrate is disposed and a ball-shaped resin cover is attached to the opening of the bulb base. (Patent Document 1)
JP 2003-151306 A

近年、照明に多様性が求められ、指向性を持って照明できるような照明具が求められてきた。
ところが、前記従来の発光ダイオードを組み込んだ電球は、白熱電球や蛍光灯に変わって仕様できるようにしたもので、全方向を均等に照明できるようにしていることから、このものでは、器具側で照射方向を規制するようにしなければならず、照明設備として大きくなるという問題がある。また。電球のバルブ内に遮光体を設置して、照射方向に指向性を持たせることも考えられるが、この場合、照明電球を器具に設置した際にその照射方向を調整することができないため、器具の配設が面倒になるという問題があった。 In recent years, there has been a demand for diversity in lighting, and there has been a demand for lighting fixtures that can illuminate with directivity.
However, the conventional light bulb incorporating the light-emitting diode can be used as a specification instead of an incandescent light bulb or a fluorescent light, and can be illuminated uniformly in all directions. There is a problem that the irradiation direction must be regulated and the lighting equipment becomes large. Also. It is conceivable that a light shield is installed in the bulb of the bulb so that the irradiation direction has directivity. However, in this case, the illumination bulb cannot be adjusted when it is installed on the fixture. There was a problem that the arrangement of was troublesome.

本発明は、このような点に着目してなされたもので、照射方向に指向性を有し、その照射方向の調整を容易に行うことのできるＬＥＤ照明電球を提供することを目的とする。   The present invention has been made paying attention to such points, and an object thereof is to provide an LED lighting bulb that has directivity in the irradiation direction and can easily adjust the irradiation direction.

上述の目的を達成するために本発明は、ハウジングを電球用口金が装着されているボディ部と、このボティ部に揺動回転可能に装着されているリング部と、リング部と一体になって揺動回転する透光性キャップ部とで構成し、複数の発光ダイオードを配置している基板を前記リング部に固定支持することにより、基板をボディ部に対して相対回転揺動可能に構成し、前記基板に複数の発光ダイオードを照射光量が多い方向と照射光量が少ない方向とが混在する状態に配設することによりＬＥＤ照明電球として照射方向性を持たせるように構成したことを特徴としている。   In order to achieve the above-mentioned object, the present invention integrates a housing with a body part on which a cap for a light bulb is attached, a ring part attached to the body part so as to be able to swing and rotate, and the ring part. It is composed of a translucent cap that swings and rotates, and a substrate on which a plurality of light emitting diodes are arranged is fixedly supported on the ring portion, so that the substrate can be rotated relative to the body portion. The LED lighting bulb is configured to have a directionality by arranging a plurality of light emitting diodes on the substrate in a state in which a direction with a large amount of light and a direction with a small amount of light are mixed. .

本発明は、商用電源に接続されている電球ソケットにこのＬＥＤ照明電球を螺着することで、ＬＥＤ照明電球に電力を供給することができ、かつ、照射光軸を方向性を持たせた状態に発光ダイオードを配置した基板を固定しているリング部材が、電球用口金を固定しているボディ部に対して揺動可能に組み付けてあることから、電球ソケットにＬＥＤ照明電球を螺着結合させた後でも、確実に照射方向を調整することができることになる。   The present invention can supply power to the LED lighting bulb by screwing the LED lighting bulb to a bulb socket connected to a commercial power source, and the irradiation optical axis has directionality. Since the ring member that fixes the substrate on which the light emitting diode is placed is assembled so as to be swingable with respect to the body part that fixes the bulb base, the LED lighting bulb is screwed and connected to the bulb socket. Even after this, the irradiation direction can be reliably adjusted.

図は、本発明の実施形態を示し、図１は全体を分解した状態で右半分を縦断した断面図、図２はハウジング部分の分解斜視図である。
このＬＥＤ照明電球は、複数の発光ダイオード(１)を並べて配置した基板(２)と、この基板(２)を収容しているハウジング(３)と、このハウジング(３)に固定した電球用口金(４)とを具備して構成してある。 FIG. 1 shows an embodiment of the present invention, FIG. 1 is a cross-sectional view in which the right half of the housing is vertically disassembled, and FIG. 2 is an exploded perspective view of a housing portion.
This LED lighting bulb includes a substrate (2) in which a plurality of light emitting diodes (1) are arranged side by side, a housing (3) that accommodates the substrate (2), and a bulb cap fixed to the housing (3). (4).

ハウジング(３)は、前記電球用口金(４)が装着されているボディ部(５)と、このボティ部(５)に揺動回転可能に装着されているリング部(６)と、リング部(６)と一体になって揺動回転する透光性キャップ部(７)とで構成してある。   The housing (3) includes a body part (5) to which the bulb cap (4) is attached, a ring part (6) attached to the body part (5) so as to be able to swing and rotate, and a ring part.

A positioning protruding piece (9) is formed so as to protrude from the upper inner peripheral surface of the body in a state exceeding the upper end surface of the body portion.

リング部(６)は、前記ボティ部(５)に形成した小突起(８)の下面に抜止め状に嵌り合う係合片(10)をその下端部に形成するとともに、周方向に並ぶ前記小突起(８)同士間の空隙に嵌り合う係合突起(11)を内周面の下端部に一定間隔隔てて配置することにより、リング部(６)を前記ボディ部(５)に相対回転を抑制するように構成してある。また、リング部(６)の上端部分には、その内周方向に突出する基板載置台(12)と回転規制片(13)とが形成してある。なお、基板載置台(12)の内周面からの突出量は前記ボディ部(５)から突出している位置決め突出片(９)とは干渉しない長さに形成してあり、回転規制片(13)の突出量は前記ボディ部(５)から突出している位置決め突出片(９)と側面同士で当接する長さに形成してある。   The ring portion (6) is formed with an engagement piece (10) fitted on the lower surface of the small protrusion (8) formed on the body portion (5) in a retaining shape at the lower end portion thereof and arranged in the circumferential direction. By disposing engagement projections (11) that fit into the gaps between the small projections (8) at the lower end portion of the inner peripheral surface at a predetermined interval, the ring portion (6) is rotated relative to the body portion (5). It is comprised so that it may suppress. A substrate mounting table (12) and a rotation restricting piece (13) projecting in the inner circumferential direction are formed at the upper end portion of the ring portion (6). The amount of protrusion from the inner peripheral surface of the substrate mounting table (12) is formed so as not to interfere with the positioning protruding piece (9) protruding from the body portion (5), and the rotation restricting piece (13 ) Is formed in such a length that the positioning projecting piece (9) projecting from the body part (5) abuts on the side surfaces.

透光性キャップ部(７)は、ポリカーボネート樹脂でドーム状に形成してあり、リング部(６)の上端縁部分外周に形成した嵌合縁部(14)に嵌着固定されるようにしてある。   The translucent cap part (7) is formed in a dome shape with polycarbonate resin, and is fitted and fixed to a fitting edge part (14) formed on the outer periphery of the upper end edge part of the ring part (6). is there.

基板(２)は、その上面に複数(例えば１２個)の発光ダイオード(１)を配置するとともに、その下面に整流回路(15)やコンデンサ(16)、あるいは抵抗(17)等を配置してＬＥＤ制御回路を形成し、この基板(２)の下面に位置する入力端子とボディ部(５)に固着した電球用口金(４)の下側突底部(18)および側面ねじ部(19)とに図示を省略したリード線で接続している。   The substrate (2) has a plurality of (for example, twelve) light emitting diodes (1) arranged on the upper surface thereof, and a rectifier circuit (15), a capacitor (16), or a resistor (17) arranged on the lower surface thereof. An LED control circuit is formed, an input terminal located on the lower surface of the substrate (2), a lower base (18) of the bulb base (4) fixed to the body (5), and a side screw (19) Are connected by lead wires (not shown).

図３は、たとえば寺院等の軒先に吊り下げられる提灯や吊下灯籠の光源として使用されるＬＥＤ照明電球での発光ダイオード(１)の配列パターンを示し、基板(２)の上面に配置した１２個の発光ダイオード(１)は、その１２個の発光ダイオード(１)の内の１０個の発光ダイオード(１ａ)が前面側を、残りの２個の発光ダイオード(１ｂ)が背面側をそれぞれ照射するように配置してある。そして、前面側を照射する１０個の発光ダイオード(１ａ)はそれぞれ光軸が１０度程度上向きとなる姿勢に配置してあり、背面側を照射するように配置した２個の発光ダイオード(１ｂ)は、それぞれ光軸が４５度程度上向きとなる姿勢に配置してある。   FIG. 3 shows an arrangement pattern of the light emitting diodes (1) in an LED lighting bulb used as a light source for a lantern or a hanging lantern, for example, at a temple or the like, and is arranged on the upper surface of the substrate (2). Of the 12 light emitting diodes (1), 10 light emitting diodes (1a) of the 12 light emitting diodes (1) irradiate the front side, and the remaining two light emitting diodes (1b) irradiate the back side. It is arranged to do. The 10 light emitting diodes (1a) that irradiate the front side are each arranged in an attitude in which the optical axis is upward about 10 degrees, and the two light emitting diodes (1b) that are arranged to irradiate the back side. Are arranged in such a posture that their optical axes are upward about 45 degrees.

また、前面側を照射するように配置した１０個の発光ダイオード(１ａ)は、前面側を一定角度範囲で照射できるように中央部分に配置した４個の発光ダイオードが、その光軸を平面視で前面方向に向かうように、残りの６個の発光ダイオードが３個づつ左右に配置され、それぞれの光軸は、平面視で前面方向に対して４５度の開き角度となるように配置してある。なお、背面側に向けて配置した２個の発光ダイオード(１ｂ)光軸は平面視でそれぞれ背面に向かうように配置してある。   In addition, ten light emitting diodes (1a) arranged to irradiate the front side have four light emitting diodes arranged in the central portion so that the front side can be irradiated within a certain angle range, and the optical axis thereof is viewed in plan view. The remaining six light-emitting diodes are arranged on the left and right so that they face toward the front, and the respective optical axes are arranged so as to have an opening angle of 45 degrees with respect to the front in the plan view. is there. The optical axes of the two light emitting diodes (1b) arranged toward the back side are arranged so as to face the back side in plan view.

発光ダイオード(１)をこのように配置したＬＥＤ照明電球では、正面側(前面)が背面側に比べて格段に明るく照明されることになるから、軒下等に取り下げられた提灯の光源として使用した場合には、建物側に背面側を位置させることにより、同じ電力で有効な照明を行えることになる。   In the LED lighting bulb with the light emitting diode (1) arranged in this way, the front side (front side) is illuminated much brighter than the back side, so it was used as the light source for the lanterns withdrawn under the eaves. In some cases, effective lighting can be performed with the same power by positioning the back side on the building side.

図４は、たとえば置灯籠や立灯籠の光源としてとして使用するＬＥＤ照明電球での発光ダイオード(１)の配列パターンを示し、発光ダイオード(１)を基板(２)に配置したもので、これは、基板(２)上に想定した仮想正方形の各辺部分にそれぞれ２個づづの発光ダイオード(１ｃ)を配置するとともに、仮想正方形の各コーナー部にそれぞれ１個の発光ダイオード(１ｄ)を配置したもので、仮想正方形の各辺部分に配置した発光ダイオード(１ｃ)の光軸は平面視で該辺に対して直交する方向を指し、正面視で２０度程度上向きとなる方向を指す姿勢に配置してあり、コーナー部に配置した各発光ダイオード(１ｄ)の光軸は平面視で対角方向を指し、正面視で２０度程度上向きとなる方向を指す姿勢に配置してある。   FIG. 4 shows an arrangement pattern of the light emitting diodes (1) in an LED lighting bulb used as a light source for, for example, a standing lantern or a standing lantern, and the light emitting diodes (1) are arranged on the substrate (2). In addition, two light emitting diodes (1c) are arranged on each side of the assumed virtual square on the substrate (2), and one light emitting diode (1d) is arranged at each corner of the virtual square. Therefore, the optical axis of the light emitting diode (1c) arranged on each side portion of the virtual square indicates a direction perpendicular to the side in a plan view and is arranged in a posture indicating an upward direction by about 20 degrees in a front view. The light axes of the respective light emitting diodes (1d) arranged at the corner portions are arranged in a posture indicating a diagonal direction in a plan view and pointing upward by about 20 degrees in a front view.

１２個の発光ダイオード(１)をこのように配置した場合には、四方に窓が形成されている灯籠の火袋内に仮想正方形の各辺が対抗する状態にＬＥＤ照明電球を設置することにより、窓を通して四方に大量の光量を供給することができる。   When twelve light-emitting diodes (1) are arranged in this way, by installing the LED lighting bulb in a state where the sides of the virtual square are opposed to each other in the sack of a lantern having windows formed on four sides. A large amount of light can be supplied in all directions through the window.

なお、上記両実施態様で各発光ダイオード(１)の光軸を斜め上向きに設定しているのは、発光ダイオード(１)が指向性(１５〜５０度)を有していることからこの指向性の範囲内で上向に配置することにより、基板(１)の表面よりも前側を照射することができることになるからである。   In the above embodiments, the light axis of each light emitting diode (1) is set obliquely upward because the light emitting diode (1) has directivity (15 to 50 degrees). This is because it is possible to irradiate the front side of the surface of the substrate (1) by arranging upward within the range of the property.

そして、上述のように、照明に指向性を必要とする場合、このＬＥＤ照明用電球は、電球用口金(４)が固定されているボディ部(５)に対して相対回転可能に組みつけたリング部(６)に、発光ダイオード(１)が所定の姿勢で取り付けられている基板(２)が固定してあることから、ＬＥＤ照明用電球を器具側のソケットに電球用口金(４)を螺合して連結したのち、リング部(６)をボディ部(５)に対して回転させることにより、基板(２)に取り付けられている発光ダイオード(１)の主照射方向を任意の方向に調整する。   As described above, when directivity is required for illumination, the LED lighting bulb is assembled so as to be rotatable relative to the body portion (5) to which the bulb base (4) is fixed. Since the substrate (2) to which the light emitting diode (1) is attached in a predetermined posture is fixed to the ring part (6), the bulb cap (4) is attached to the socket on the appliance side of the LED lighting bulb. After the screw connection, the ring part (6) is rotated with respect to the body part (5), so that the main irradiation direction of the light emitting diode (1) attached to the substrate (2) is set to an arbitrary direction. adjust.

本発明にかかるＬＥＤ照明用電球は、前記したように、壁面に近接して配置した提灯や吊るし灯籠の光源や、置き灯籠や立灯籠の光源等、照射方向に指向性を持たせたい個所に配置する。   As described above, the LED lighting bulb according to the present invention has a directivity in the irradiation direction, such as a lantern or a light source of a hanging lantern, a light source of a lantern or a standing lantern, which is arranged close to the wall surface.
