Description
本発明は、電球形の光源ユニットの技術に関するものである。 The present invention relates to a technology of a light bulb-shaped light source unit.
灯体を自由自在に回転させて、発光ダイオードからの光の照射方向が所望に調整可能とする技術がある。（例えば、特許文献１参照。） There is a technology in which the lamp body can be freely rotated to adjust the irradiation direction of light from the light emitting diode as desired. (For example, refer to Patent Document 1.)
しかしながら、ユーザーが照射方向を可変する必要があり、手間がかかっていた。
また、球体の表面に近い部分にＬＥＤが実装されるため、ＬＥＤが実装できる数が限られるため、複数のＬＥＤを実装して高出力の光出力を得ることが難しく、複数のＬＥＤを実装するにはＬＥＤ電球の形状が大きくなるという課題があった。
However, it is necessary for the user to change the irradiation direction, which is troublesome.
In addition, since the LEDs are mounted on a portion close to the surface of the sphere, the number of LEDs that can be mounted is limited. Therefore, it is difficult to mount a plurality of LEDs to obtain a high output light output, and a plurality of LEDs are mounted. Has a problem that the shape of the LED bulb becomes large.
本発明は、照明器具のソケットの位置によらず、本来の配光に近づける小型の電球形の光源ユニットを得ることを目的とする。 An object of the present invention is to obtain a small light bulb-shaped light source unit that can be brought close to the original light distribution regardless of the position of the socket of the lighting fixture.
本発明によれば、照明器具のソケットの位置に対応して発光面を回転させることができ、本来の配光に近づけることができるとともに、外形形状を小型化することができる。 ADVANTAGE OF THE INVENTION According to this invention, a light emission surface can be rotated corresponding to the position of the socket of a lighting fixture, it can be approximated to original light distribution, and an external shape can be reduced in size.

The rotor 3 is rotatably attached to a rotary bearing 23.
回転子３は、回転軸受け部２３に回転可能に係着する回転軸部３１を有する。 The rotor 3 has a rotation shaft portion 31 that is rotatably attached to the rotation bearing portion 23.
支持部４は、一方側がネジ山部２１に電気的に接触するとともに、他方側に軸穴４ａ１を有する第１の支持部４ａと、一方側が凸部２２に電気的に接触するとともに、他方側に軸穴４ｂ１を有する第２の支持部４ｂを有する。 The support portion 4 is electrically in contact with the screw thread portion 21 on one side, the first support portion 4a having the shaft hole 4a1 on the other side, and is electrically in contact with the convex portion 22 on the other side. Has a second support portion 4b having a shaft hole 4b1.
発光部６は、円筒形状をなし、円形部６１ａまたは円形部６１ｂの中心線の両端側かつ側壁の中央部よりも一方側に備えられる軸受け穴６２を備え、軸受け穴６２よりも離れた円形部６１ａにＬＥＤ５が取り付けられる。 The light-emitting portion 6 has a cylindrical shape, and includes a bearing hole 62 provided on both ends of the center line of the circular portion 61a or the circular portion 61b and on one side of the central portion of the side wall, and is a circular portion separated from the bearing hole 62. LED5 is attached to 61a.
カバー８は、半円球状の透明な第１のカバー８ａと、口金部２が挿入される穴部８ｂ１を有し、半円球状の透明な第２のカバー８ｂを備える。 The cover 8 includes a semispherical transparent first cover 8a and a hole 8b1 into which the cap portion 2 is inserted, and includes a semispherical transparent second cover 8b.
次に、この電球形の光源ユニット１の使用状態について説明する。
図５及び図６は、図１に示す電球形の光源ユニットの使用状態を示す図である。
Next, the use state of this light bulb-shaped light source unit 1 will be described.
5 and 6 are diagrams showing a use state of the light bulb-shaped light source unit shown in FIG.
図５は、斜め方向に配置されるソケットに、電球形の光源ユニットを取り付けた状態を示している。 FIG. 5 shows a state in which a light bulb-shaped light source unit is attached to a socket arranged in an oblique direction.
このとき、軸受け穴６２が一方側に偏った位置にあるので、発光部６の自重によって、回転子３および発光部６は回転する。 At this time, since the bearing hole 62 is in a position biased to one side, the rotor 3 and the light emitting unit 6 are rotated by the weight of the light emitting unit 6.
したがって、ＬＥＤ５が取り付けられる円形部６１ａが下面方向に向く。 Therefore, the circular portion 61a to which the LED 5 is attached faces in the lower surface direction.
図６は、真上方向に配置されるソケットに、電球形の光源ユニットを取り付けた状態を示している。 FIG. 6 shows a state in which a light bulb-shaped light source unit is attached to a socket arranged in the directly upward direction.
このとき、軸受け穴６２が一方側に偏った位置にあるので、発光部６の自重によって、回転子３および発光部６は回転する。 At this time, since the bearing hole 62 is in a position biased to one side, the rotor 3 and the light emitting unit 6 are rotated by the weight of the light emitting unit 6.
したがって、ＬＥＤ５が取り付けられる円形部６１ａが下面方向に向く。 Therefore, the circular portion 61a to which the LED 5 is attached faces in the lower surface direction.
このように、電球形の光源ユニット１が取り付けるソケットの方向によらず、ＬＥＤ５が取り付けられる円形部６１ａが下面方向を向くように、回転子３および発光部６が回転するので、電球形の光源ユニット１が発光する光を本来の配光に近づけることができる。 Thus, the rotor 3 and the light emitting unit 6 rotate so that the circular portion 61a to which the LED 5 is attached faces the lower surface regardless of the direction of the socket to which the bulb-type light source unit 1 is attached. The light emitted from the unit 1 can be brought close to the original light distribution.
