Description

本発明は、自動車用ハロゲン電球代替のためのＬＥＤ電球に関するもので、もっと詳しく言うと、高電力非効率のハロゲン電球を低電力高効率のＬＥＤ電球に交代はするが、上記ＬＥＤ電球から照射された光を反射して光を拡張し、外部に照射される光の範囲を一定に維持できる自動車用ハロゲン電球代替のためのＬＥＤ電球に関するものである。   The present invention relates to an LED bulb as a substitute for a halogen bulb for automobiles. More specifically, the present invention replaces a high-power and inefficient halogen bulb with a low-power and high-efficiency LED bulb, but is irradiated from the LED bulb. The present invention relates to an LED bulb as an alternative to a halogen bulb for automobiles that can reflect the reflected light to expand the light and maintain a constant range of light irradiated to the outside.

二輪車を含む自動車は、外部環境および時間によって前方に光を照射して運転者の視野を確保し、他の車両に車両の進行経路を知らせる目的で照明（ランプ）が備わる。   Automobiles including two-wheeled vehicles are equipped with illumination (lamps) for the purpose of ensuring the driver's field of view by irradiating light forward depending on the external environment and time, and notifying other vehicles of the traveling route of the vehicle.

このような照明は使用する目的によって区分されるが、前方を照らす目的のヘッドランプと、車両の進行経路を知らせる目的の方向指示燈（ターンシグナル）、霧・雨天時にヘッドランプとともに運転者の視野確保および車両の位置を知らせるためのフォグランプと、車両の後進時に点灯される後進燈などがある。   Such lighting is classified according to the purpose of use, but the headlamp that illuminates the front, the direction indicator (turn signal) that informs the traveling path of the vehicle, and the driver's field of view along with the headlamp in fog or rainy weather There are fog lights for securing and notifying the position of the vehicle, and a reverse lamp that is turned on when the vehicle moves backward.

従来の照明に使用される光源としては普通ハロゲン（Ｈａｌｏｇｅｎ）電球が使用されている。ハロゲン電球は２２０Ｖを１２Ｖに変換して使用するもので、値段が安いため多様に使用されているが、使用中に発生する熱が多く、使用する電気量に比べて低輝度を持ち、寿命が短いため交代周期が短い問題点があった。   As a light source used for conventional illumination, a halogen bulb is normally used. Halogen bulbs are used by converting 220V to 12V, and are used in a variety of ways because of their low price. However, they generate a lot of heat during use, have lower brightness than the amount of electricity used, and have a long life. There was a problem that the alternation cycle was short because it was short.

上記ハロゲン電球を利用した従来技術としては大韓民国特許第１０−２５９７８８号があるが、上記従来技術は図１に図示されたように光源としてハロゲンランプを使用し、上記ハロゲンランプから照射された光を反射させる反射板を通じて照射された光を前方に照射することになる。   Korean Patent No. 10-259788 is a conventional technique using the halogen bulb. However, the conventional technique uses a halogen lamp as a light source as shown in FIG. The light irradiated through the reflecting plate to be reflected is irradiated forward.

しかし、上記従来技術はハロゲン電球から照射された光の照射角度が正面の上方および下方に同時に照射されて光の凝集度が落ち、さらに自動車のヘッドランプの場合、反対側の方向から来る運転者の視野を妨害する問題点があった。   However, in the above prior art, the angle of light emitted from the halogen bulb is simultaneously irradiated above and below the front to reduce the degree of light aggregation, and in the case of an automobile headlamp, the driver coming from the opposite direction There was a problem that disturbed the field of vision.

また、上述したように、ハロゲン電球は使用中に発熱量が多くて寿命が短い短所のため、交代周期が頻繁になって維持保守による費用が増加し、使用後ハロゲン電球の廃棄による環境汚染および廃棄費用増加のような問題点があった。   In addition, as mentioned above, halogen bulbs have a disadvantage that they generate a large amount of heat during use and have a short life span. There were problems such as increased disposal costs.

また、上記ハロゲン電球は輝度が低いため、前方に照射される光の明るさが落ち、特に反射板を通じて反射された後、照射される光の明るさが弱い問題点があった。   In addition, since the halogen bulb has a low luminance, the brightness of the light irradiated forward decreases, and in particular, the brightness of the light irradiated after being reflected through the reflecting plate is weak.

大韓民国特許第１０−２５９７８８号公報Korean Patent No. 10-259788

図２ないし図５に図示されたように、本発明によるＬＥＤ電球１は、本体１０と、光源部２０と、カバー３０および反射体４０を含めて作られる。 As shown in FIGS. 2 to 5, the LED bulb 1 according to the present invention includes a main body 10, a light source unit 20, a cover 30 and a reflector 40.

上記本体１０は、自動車の照明部２に挿入されるプラグ１１が備わり、内側にＰＣＢ１２を備え、片側に後述する光源部２０が結合されるねじ孔１３が形成され、外周面に多数の放熱突起１４が備わり、上記光源部２０で発生した熱を外部に排出するようになる。   The main body 10 is provided with a plug 11 to be inserted into an illumination unit 2 of an automobile, includes a PCB 12 on the inside, a screw hole 13 to which a light source unit 20 to be described later is coupled is formed on one side, and a large number of heat dissipation protrusions on an outer peripheral surface 14 is provided, and heat generated by the light source unit 20 is discharged to the outside.

この時、上記本体１０は、耐久性を向上させて上述した放熱突起１４とともに熱の排出効率を高めるために、熱伝統率が高い金属材で作るのが望ましく、熱伝統率が高い金属材の代表的な素材としてアルミがある。   At this time, the main body 10 is preferably made of a metal material having a high heat tradition rate in order to improve durability and increase the heat discharge efficiency together with the heat dissipation protrusion 14 described above. A typical material is aluminum.

上記本体１０に具備さえたＰＣＢ１２は、本体１０の片側に具備されたプラグ１１と連結され、自動車の照明部２にプラグ１１が挿入されることで、ＰＣＢ１２で電源を承認され、承認された電源を通じてＰＣＢ１２は光源部２０を制御することになる。   The PCB 12 provided in the main body 10 is connected to the plug 11 provided on one side of the main body 10, and the power is approved by the PCB 12 by inserting the plug 11 into the lighting unit 2 of the automobile. Through this, the PCB 12 controls the light source unit 20.

上記ねじ孔は本体１０の片側に少なくとも一つ以上形成され、光源部２０が配置された後に光源部２０に貫通結合された結合ボルト２２がねじ結合される。   At least one screw hole is formed on one side of the main body 10, and after the light source unit 20 is disposed, a coupling bolt 22 penetratingly coupled to the light source unit 20 is screwed.

また、上記本体１０には後述するカバー３０が挿入固定される結合溝１５が形成され、上記結合溝１５はカバー３０に形成された結合突起３１が内側に挿入固定される。   The main body 10 is formed with a coupling groove 15 into which a cover 30 to be described later is inserted and fixed. In the coupling groove 15, a coupling protrusion 31 formed on the cover 30 is inserted and fixed inside.

上記光源部２０は、ＰＣＢ１２の制御を通じて点灯されて光を前方に照射するもので、値段が安くて低電力、高輝度の長所があり、照射される光の直進性が高いＬＥＤ（Ｌｉｇｈｔ Ｅｍｉｔｔｉｎｇ Ｄｉｏｄｅ）２１が使用され、上記ＬＥＤ２１は上記本体１０の片側に形成されたねじ孔１３に結合ボルト２２を通じて一体に固定される。   The light source unit 20 is lit through the control of the PCB 12 and irradiates light forward. The light source unit 20 has advantages such as low price, low power, and high brightness, and has high straightness of the irradiated light (Light Emitting Diode). ) 21 is used, and the LED 21 is integrally fixed to a screw hole 13 formed on one side of the main body 10 through a coupling bolt 22.

上記光源部２０を構成するＬＥＤ２１は少なくとも一つ以上具備され、青、赤、黄色など様々な色相が単独または混合されて使用できるが、これは本発明によるＬＥＤ電球１が使用される位置によって選択的に使用される。つまり、自動車の制動燈（ストップライト）のように赤で表現するべき部分に使用される場合は赤のＬＥＤを使用し、方向指示燈（ターンシグナル）のように黄色で表現するべき部分に使用される場合は黄色のＬＥＤを使用し、前照燈（ヘッドライト）のように前方に向けて多くの量の光が必要な場合は複数のＬＥＤを配置して使用することができる。   At least one LED 21 constituting the light source unit 20 is provided, and various hues such as blue, red, and yellow can be used alone or in combination, and this is selected according to the position where the LED bulb 1 according to the present invention is used. Used. In other words, if it is used for a part that should be expressed in red, such as a car's braking light (stoplight), use a red LED, and use it for a part that should be expressed in yellow, such as a turn signal. In this case, a yellow LED is used, and when a large amount of light is required toward the front, such as a headlight, a plurality of LEDs can be arranged and used.

上記カバー３０は本体１０の片側に結合され、上記光源部２０を通じて照射された光が前方に向けて照射できるようにするもので、光が通過する透明な素材で作られ、両側端が貫通された円筒形の形状で作られ、片側端は上記本体１０に結合され、他側端には上記光源部２０の光を反射させる反射体４０が結合される。   The cover 30 is coupled to one side of the main body 10 so that the light emitted through the light source unit 20 can be emitted forward, and is made of a transparent material through which light passes, and both side ends are penetrated. The one end is coupled to the main body 10 and the other end is coupled to a reflector 40 that reflects the light from the light source unit 20.

上記カバー３０は光が通過できる透明な素材で作られたもので、代表的な素材としてはポリメチルメタクリレート（ＰＭＭＡ）、ポリカーボネート（ＰＣ）などがある。   The cover 30 is made of a transparent material through which light can pass. Typical materials include polymethyl methacrylate (PMMA) and polycarbonate (PC).

上記カバー３０には本体１０との結合のための結合突起３１が具備されるものの、上記本体１０に結合される片側に放射状に多数が具備されて本体１０の結合溝１５に挿入固定され、この時、上記結合突起３１は上記結合溝１５に挿入された後、使用者がカバー３０の外周面を加圧した後に離脱させる形で着脱できるように結合される。   Although the cover 30 is provided with coupling protrusions 31 for coupling with the main body 10, a large number are radially provided on one side coupled to the main body 10 and inserted and fixed in the coupling groove 15 of the main body 10. At this time, after the coupling protrusion 31 is inserted into the coupling groove 15, the coupling protrusion 31 is detachably coupled in such a manner that the user presses the outer peripheral surface of the cover 30 and then removes it.

また、上記カバー３０の内側には光源部２０から照射された光を屈曲させて後述する反射体４０で光を伝達するための屈曲面３２が形成されるが、上記屈曲面３２はカバー３０の内壁から中央に向けて突出形成され、中央部に光源部２０から照射された光が前方に向けて通過するように貫通孔３３が形成される。   In addition, a bent surface 32 is formed on the inner side of the cover 30 to bend light emitted from the light source unit 20 and transmit light by a reflector 40 described later. A through hole 33 is formed so as to protrude from the inner wall toward the center, and so that light emitted from the light source unit 20 passes forward at the center.

この時、上記屈曲面３２は環形で形成された多数の突起で作られることもあるが、おおよそ凹状を持つ円形で作られることもある。   At this time, the bent surface 32 may be made of a large number of projections formed in an annular shape, but may be made of a circular shape having a substantially concave shape.

また、上記屈曲面３２で、光源部２０から照射された光が進入する一面は、外側から中央に前方に向けて漸進的に斜めに形成された傾斜面３４がもっと形成されるが、上記傾斜面３４は光源部２０から照射された光の進入角度に相応する角度で形成され、屈曲時に損失される光を減すためにしたものである。   In addition, the curved surface 32 on which the light irradiated from the light source unit 20 enters is further formed with an inclined surface 34 that is gradually inclined from the outside toward the center toward the front. The surface 34 is formed at an angle corresponding to the incident angle of the light emitted from the light source unit 20, and is for reducing light lost at the time of bending.

上記反射体４０は上記カバー３０の片側に固定結合され、上記屈曲面３２と向き合う方向に光源部２０および屈曲面３２を通じて照射された光を、照明部２に備わった半球形の反射鏡３で再反射させるためのもので、カバー３０に挟み結合され、屈曲面３２と向き合う方向に突出され、断面形状がおおよそ´＜´字形状を持つが、屈曲面３２と向き合う面を光を反射させる銀、アルミなどのような素材でメッキさせて形成される。   The reflector 40 is fixedly coupled to one side of the cover 30, and light irradiated through the light source unit 20 and the bent surface 32 in a direction facing the bent surface 32 is reflected by the hemispherical reflecting mirror 3 provided in the illumination unit 2. Silver for re-reflection, which is sandwiched between the cover 30 and protruded in a direction facing the bent surface 32. The cross-sectional shape is approximately '<', but the surface facing the bent surface 32 reflects light. It is formed by plating with a material such as aluminum.

この時、上記反射体４０で上記屈曲面３２と向き合う一面は、中央は外側に突出された突出面４１ａが形成され、上記突出面４１ａの両端から緩やかな曲面で下向きに傾いた湾曲面４１Ｂが形成される。   At this time, one surface of the reflector 40 that faces the bent surface 32 is formed with a projecting surface 41a projecting outward at the center, and a curved surface 41B that is gently curved from both ends of the projecting surface 41a and tilted downward is formed. It is formed.

上記突出面４１ａは上記光源部２０から照射された光の中、屈曲面３２に形成された貫通孔３３を通過して直接伝達される光を反射させる面で、屈曲面３２と向き合う方向に向けて突出形成されて貫通孔３３を通過した光源部２０の光が突出面４１ａに当った後に反射されて半球形の反射鏡３に伝達され、上記湾曲面４１ｂは上記光源部２０から照射された光と屈曲面３２を通過した光を反射させて上記反射鏡３に伝達する面で、上記突出面４１ａの突出方向と反対方向に緩やかな曲線で形成され、相接した光を後方に配置された反射鏡３に伝達することである。   The protruding surface 41a is a surface that reflects the light directly transmitted through the through hole 33 formed in the bent surface 32 out of the light emitted from the light source unit 20, and faces the direction facing the bent surface 32. Then, the light of the light source unit 20 that has been formed and passed through the through hole 33 is reflected after being impinged on the projecting surface 41 a and transmitted to the hemispherical reflecting mirror 3, and the curved surface 41 b is irradiated from the light source unit 20. A surface that reflects the light and the light that has passed through the bent surface 32 and transmits the reflected light to the reflecting mirror 3, is formed in a gentle curve in the direction opposite to the protruding direction of the protruding surface 41a, and the adjacent light is disposed rearward. Is transmitted to the reflecting mirror 3.

また、上記湾曲面４１ｂの端４１ｃはカバー３０の内面と相接するが、反射体４０がカバー３０にむりやり挟む形で結合されるように上記端４１ｃがカバー３０の内面直径に比べて大きく形成されるが、加圧された力によって弾性変形されることでむりやり挟まれた後に任意に離脱されるのを防ぎ、さらに反射体４０にはカバー３０の内面に挿入される深さを制限する段差４２が形成され、反射体４０から外側に露出される一面に広告用文句または図形などを具備された広告部４３がもっと形成される。   The end 41c of the curved surface 41b is in contact with the inner surface of the cover 30, but the end 41c is formed to be larger than the inner surface diameter of the cover 30 so that the reflector 40 is coupled to the cover 30 so as to be pinched. However, it is prevented from being arbitrarily separated after being pinched by being elastically deformed by a pressurized force, and further, the reflector 40 has a step that limits the depth of insertion into the inner surface of the cover 30. 42 is formed, and an advertisement part 43 having an advertising phrase or a figure on one surface exposed to the outside from the reflector 40 is further formed.

上記のように作られた本発明によるＬＥＤ電球１の使用状態を、図４および図５ａ、図５ｂを参照してよく見ると以下のとおりである。   The use state of the LED bulb 1 according to the present invention produced as described above will be described below with reference to FIGS. 4, 5a, and 5b.

まず、反射鏡３を含めて作られた自動車の照明部２に本体１０のプラグ１１を通じて結合し、上記プラグ１１を通じて承認された電源が本体１０内側のＰＣＢ１２を通じて光源部２０のＬＥＤ２１に伝達され、ＬＥＤ２１が点灯される。   First, it is coupled to the lighting unit 2 of the automobile including the reflecting mirror 3 through the plug 11 of the main body 10, and the approved power supply is transmitted to the LED 21 of the light source unit 20 through the PCB 12 inside the main body 10, The LED 21 is turned on.

点灯されたＬＥＤ２１から照射された光は、図５ａおよび図５ｂに図示されたように照射される光の角度によって反射体４０の突出面４１ａに再反射された後、反射鏡に伝達されるか（図５ａ参照）、屈曲面３２に引き込まれた角度および反射された角度によって上記反射体４０の湾曲面４１ｂを通じて再反射された後、反射鏡３に伝達されてから外部に伝達される。（図５ｂ参照）   Whether the light emitted from the lit LED 21 is re-reflected by the projecting surface 41a of the reflector 40 according to the angle of the irradiated light as shown in FIGS. 5a and 5b, and then transmitted to the reflecting mirror. (Refer to FIG. 5a) After being re-reflected through the curved surface 41b of the reflector 40 by the angle drawn into the bent surface 32 and the reflected angle, it is transmitted to the reflecting mirror 3 and then transmitted to the outside. (See Figure 5b)

したがって、上記ＬＥＤ２１で照射された光が屈曲面３２および反射体４０を通じて外部と反射鏡３に伝達され、光が照射される範囲を一定範囲に形成して前方に照射される光の明るさを高め、照射される光の範囲が一定に形成でき、値段が安くて低電力高輝度の性質を持ったＬＥＤを光源として使用することで維持保守費用が節減できる効果がある。   Therefore, the light irradiated by the LED 21 is transmitted to the outside and the reflecting mirror 3 through the bent surface 32 and the reflector 40, and the brightness of the light irradiated forward is formed by forming a range in which the light is irradiated in a certain range. The range of irradiated light can be increased, and the maintenance cost can be reduced by using a low-cost, high-brightness LED as a light source.
