Description

本考案は、自動車や二輪車等の車両に搭載されるLED灯具、具体的には、長時間点灯動作を行った場合でも、LED灯具の制御異常に起因するハイフラッシャー現象、ワーニング表示を発生しないLED灯具に関する。   The present invention relates to an LED lamp mounted on a vehicle such as an automobile or a motorcycle, specifically, an LED that does not generate a high flasher phenomenon or a warning display due to an abnormal control of the LED lamp even when the lighting operation is performed for a long time. It relates to lighting equipment.

自動車等の車両の左右側にはウインカーが搭載されている。このウインカーは、バルブを点滅することにより進行方向を指示するものである。自動車等の左右側に搭載されたウインカーの内、例えば、一方のウインカーのバルブが切れる場合がある。この場合、車両側に設けられた制御部は、一方のバルブに電流が流れていないことを検出し、他方のウインカーのバルブの点滅周期を早くさせるハイフラッシャーの状態にさせる。これにより、バルブが切れたことを運転者に知らせることができる。
ウインカー灯具以外の、テールランプ、バックランプにおいても、バルブが切れた際に、ワーニング(異常を示す表示灯)等が表示される。
Blinkers are mounted on the left and right sides of vehicles such as automobiles. This turn signal indicates a traveling direction by blinking a valve. Among the winkers mounted on the left and right sides of an automobile or the like, for example, one of the winker valves may be cut off. In this case, the control unit provided on the vehicle side detects that no current is flowing through one of the valves, and puts it into a high flasher state that accelerates the blinking cycle of the valve of the other winker. As a result, the driver can be notified that the valve has expired.
Also in the tail lamp and the back lamp other than the blinker lamp, a warning (indicator indicating abnormality) or the like is displayed when the bulb is cut off.

近年では、自動車等の照明、信号灯具等にLEDが用いられている。このうち、LED灯具について、LEDが点灯した時に、純正のウインカーのバルブと同等の所定の消費電力に設定している。しかしながら、LEDに流れる電流はわずかであり、このときの消費電力は上記所定の消費電力に満たないため、制御部は、LED灯具が故障していると判断(誤認)し、LEDの点灯周期を早くするように制御する(ハイフラの状態にする)。
ウインカー灯具以外の、テールランプ、バックランプにおいても、純正バルブと消費電力が異なった際に、ワーニング(異常を示す表示灯)等が表示される。
In recent years, LEDs have been used for lighting of automobiles, signal lamps, and the like. Among these, the LED lamp is set to a predetermined power consumption equivalent to that of a genuine winker bulb when the LED is lit. However, since the current flowing through the LED is small and the power consumption at this time is less than the predetermined power consumption, the control unit determines that the LED lamp has failed (misidentification), and determines the LED lighting cycle. Control to make it faster (to make it a hi-flat state).
Also in tail lamps and back lamps other than turn signal lamps, a warning (indicating lamp indicating abnormality) or the like is displayed when the power consumption differs from that of a genuine bulb.

このように、制御部の誤認によるハイフラッシャー現象を防止するために、特許文献1に記載の技術のように、LEDに電流を流す前に、スイッチ素子と抵抗に電流を流す等様々な対策が施されている。   As described above, in order to prevent the high flasher phenomenon due to misidentification of the control unit, various measures such as flowing current to the switch element and the resistor before flowing current to the LED as in the technique described in Patent Document 1. It has been subjected.

特許第5947964号公報Japanese Patent No. 5947964

LED灯具の制御異常に起因するハイフラッシャー現象、ワーニング表示が発生する原因は、LEDに流れる電流がわずかであり、そのときの消費電力が所定の消費電力に満たないことにある。しかも、LEDの発光により熱が発生するため、LED灯具を長時間作動させたときには、当該発生熱により内部に取り付けられた抵抗の抵抗値が低下する等により、ハイフラッシャー現象が発生する。   The cause of the high flasher phenomenon and the warning display due to the abnormal control of the LED lamp is that the current flowing through the LED is very small and the power consumption at that time is less than the predetermined power consumption. Moreover, since heat is generated by the light emission of the LED, when the LED lamp is operated for a long time, a high flasher phenomenon occurs due to a decrease in the resistance value of the resistor attached inside due to the generated heat.

そこで、考案者はLED灯具に流れる電流値の経時変化および制御部の制御異常に起因するハイフラッシャー現象やワーニング表示が生じたときの消費電力に着目し、LEDに直列接続された抵抗の値を適切な値にすることにより、また、LEDから発生する熱を抵抗に与えないようにすることにより、長時間点灯を行った場合でも、LED灯具の制御異常に起因するハイフラッシャー現象、ワーニング表示は発生しないことを知見し、本考案を完成させた。   Therefore, the inventor pays attention to the power consumption when a high flasher phenomenon and a warning display occur due to the temporal change of the current value flowing through the LED lamp and the control abnormality of the control unit, and the value of the resistance connected in series with the LED is determined. Even if the lamp is turned on for a long time by setting the appropriate value, and by preventing the heat generated from the LED from being applied to the resistor, the high flasher phenomenon and warning display caused by abnormal control of the LED lamp are Knowing that it does not occur, I completed the present invention.

本考案は、長時間点灯を行った場合でも、LED灯具の制御異常に起因するハイフラッシャー現象、ワーニング表示は発生しないLED灯具を提供することを目的とする。   An object of the present invention is to provide an LED lamp that does not generate a high flasher phenomenon and a warning display due to abnormal control of the LED lamp even when the lamp is lit for a long time.

本考案に係るLED灯具は、上記課題を解決するために、複数のLEDと、LEDと並列に接続された冷却ファンと、を有し、LEDの温度を100℃を超えないように、冷却ファンによる送風によりLEDを冷却することを特徴とする。   In order to solve the above problems, an LED lamp according to the present invention has a plurality of LEDs and a cooling fan connected in parallel with the LEDs, and the cooling fan does not exceed 100 ° C. in temperature of the LEDs. The LED is cooled by blowing air.

本考案によれば、複数のLEDは冷却ファンをLEDに並列接続する。定電流回路を介してLED・冷却ファンに直流電流が流れる。このときに流れる電流が約0.05A以上である。LED灯具は直流電流により発光し、LEDの温度が上昇する。LEDの温度が120℃を超えた場合、LEDが故障する。またLEDの温度が100℃を超えるとハイフラッシャー現象、ワーニング表示が出る可能性が高い。このため、冷却ファンによりLEDを100℃以下とすることにより、LEDの故障は抑えられるとともに、ハイフラッシャー現象は発生しない。   According to the present invention, the plurality of LEDs connect the cooling fan to the LEDs in parallel. A direct current flows to the LED / cooling fan via the constant current circuit. The current flowing at this time is about 0.05 A or more. The LED lamp emits light by a direct current, and the temperature of the LED rises. When the temperature of the LED exceeds 120 ° C., the LED fails. When the LED temperature exceeds 100 ° C., there is a high possibility that a high flasher phenomenon and a warning display will appear. Therefore, by setting the LED to 100 ° C. or less with the cooling fan, the failure of the LED can be suppressed and the high flasher phenomenon does not occur.

また、本考案にかかるシーケンシャルLED灯具は、前記LEDが実装されたLED基板を含む略円筒形状のLED部材を有し、前記LEDは、前記LED部材の表面に取り付けられ、前記LED部材の内部に前記冷却ファンが挿入されたことを特徴とする。   Further, the sequential LED lamp according to the present invention has a substantially cylindrical LED member including an LED substrate on which the LED is mounted, and the LED is attached to the surface of the LED member, and inside the LED member. The cooling fan is inserted.

LEDの発光により発熱する発光熱を冷却ファンによって効率よく冷却するため、冷却ファンとLEDとを離間させる。これにより、LED灯具の制御異常によるハイフラッシャー現象の発生を防止することができる。   In order to efficiently cool the radiant heat generated by the light emission of the LED by the cooling fan, the cooling fan and the LED are separated. Thereby, generation | occurrence | production of the high flasher phenomenon by control abnormality of a LED lamp can be prevented.

ここで、LEDの種類や色、数については特に問わず、また複数個のLEDで組なしたLED群を1つのLEDとして取り扱ってもよい。この場合、それぞれのLEDが直列接続されていてもよく並列接続されていてもよく、直列接続と並列接続を組み合わせたものであってもよい。   Here, the type, color, and number of the LEDs are not particularly limited, and an LED group formed by a plurality of LEDs may be handled as one LED. In this case, each LED may be connected in series, may be connected in parallel, and may be a combination of series connection and parallel connection.

本考案によれば、複数のLEDを100℃を超えないように冷却ファンで冷却することにより、制御部は、LED灯具が故障していると誤認することなく、LED灯具の制御異常に起因するハイフラッシャー現象、ワーニング表示は発生しない。

以下、本考案の実施例に係るLED灯具(自動車に取り付ける正規品のLED灯具の代替品として用いられる。以下、単に「LED灯具」という。)について、図面に基づいて詳細に説明する。   Hereinafter, an LED lamp according to an embodiment of the present invention (used as an alternative to a regular LED lamp attached to an automobile. Hereinafter, simply referred to as “LED lamp”) will be described in detail with reference to the drawings.

図1は、本考案の実施例に係るLED灯具の外観斜視図である。実施例1に係るLED灯具10は、LED1aを3個、直列に並列したLED群1を1組とし、このLED群1を6個並列に接続したものを基本とする。
LED1aは、金属製(アルミニウム製)で円筒状からなるLED固定部材2の表面に固定されている。そして、LED固定部材2はベース部材3(アルミニウム製)に一体となるように固定されている。LED固定部材2に固定されている側におけるベース部材3の端部の外周形状は、LED固定部材2の外周形状と略一致している。LED固定部材の外周直径は、取り付ける車両における正規品のLED灯具の大きさにより決定されるが、概ね1〜3cm程度であり、内周直径は、後述する冷却ファン6の大きさにより決定されるが、概ね0.5〜2cm程度である。
FIG. 1 is an external perspective view of an LED lamp according to an embodiment of the present invention. The LED lamp 10 according to the first embodiment is basically composed of three LEDs 1a, one LED group 1 in series, and six LED groups 1 connected in parallel.
The LED 1a is made of metal (made of aluminum) and fixed to the surface of the LED fixing member 2 having a cylindrical shape. The LED fixing member 2 is fixed to the base member 3 (made of aluminum) so as to be integrated. The outer peripheral shape of the end portion of the base member 3 on the side fixed to the LED fixing member 2 substantially matches the outer peripheral shape of the LED fixing member 2. The outer peripheral diameter of the LED fixing member is determined by the size of a regular LED lamp in the vehicle to be attached, but is approximately 1 to 3 cm, and the inner peripheral diameter is determined by the size of the cooling fan 6 described later. However, it is about 0.5 to 2 cm.

図2に示すように、冷却ファン6は、冷却ファン保持部材5の上方に保持され、この冷却ファン保持部材5の突出部5aがLED固定部材2の内部に挿入されることにより、LED固定部材2の内部に冷却ファン6が挿入される状態となっている。
この冷却ファン保持部材5は、金属製(アルミニウム製)で、その上部(LED固定部材2の挿入側とは反対側)の外周直径より、下部(LED固定部材2の挿入側)の外周直径の方が長く、冷却ファン保持部材の内周直径は上部・下部いずれも等しい略円錐台筒形状(略円錐台形状に貫通孔が形成された形状)である。そして、この冷却ファン保持部材5の下部には、その外周直径がLED固定部材の内周直径より短く、内周直径が冷却ファン保持部材5の内周直径と等しい円筒形状の突出部5aが一体となって固定されている。そして、冷却ファン保持部材の内部と突出部の内部とは連続している。この冷却ファン保持部材5の内部には、その内周壁に固定された冷却ファン6を保持するための金具(図示しない)が設けられている。この金具を用いて冷却ファン6が冷却ファン保持部材5に保持されている。このとき、冷却ファン6と冷却ファン保持部材5との間に間隙を設ける。このように構成することで、空気が断熱材としての役割を果たすことができる。
As shown in FIG. 2, the cooling fan 6 is held above the cooling fan holding member 5, and the protrusion 5 a of the cooling fan holding member 5 is inserted into the LED fixing member 2, whereby the LED fixing member 2 is inserted into the cooling fan 6.
This cooling fan holding member 5 is made of metal (made of aluminum), and has an outer diameter of the lower portion (on the insertion side of the LED fixing member 2) than the outer diameter of the upper portion (the side opposite to the insertion side of the LED fixing member 2). The cooling fan holding member has a substantially circular truncated cone shape (a shape in which a through hole is formed in a substantially truncated cone shape) in which the inner diameter of the cooling fan holding member is the same for both the upper part and the lower part. The lower part of the cooling fan holding member 5 is integrally provided with a cylindrical protrusion 5a having an outer peripheral diameter shorter than the inner peripheral diameter of the LED fixing member and an inner peripheral diameter equal to the inner peripheral diameter of the cooling fan holding member 5. It is fixed. And the inside of a cooling fan holding member and the inside of a protrusion part are continuing. Inside the cooling fan holding member 5, a metal fitting (not shown) for holding the cooling fan 6 fixed to the inner peripheral wall is provided. The cooling fan 6 is held by the cooling fan holding member 5 using this metal fitting. At this time, a gap is provided between the cooling fan 6 and the cooling fan holding member 5. By comprising in this way, air can play the role as a heat insulating material.

冷却ファン6は、市販されているファンを用いる。この冷却ファン6は、金具を用いて冷却ファン保持部材5に保持されている。このとき、冷却ファン保持部材5の内部と突出部5aの内部に収納された状態となるように、冷却ファン6は冷却ファン保持部材5に保持される。そして、冷却ファンの回転により、冷却ファン保持部材5の内部に送風することにより、LED1aを冷却する。
この冷却ファン保持部材5は、その突出部5aがLED固定部材2の内部に挿入され、連結部材7(連結金具)を用いてLED固定部材2に連結される。
As the cooling fan 6, a commercially available fan is used. The cooling fan 6 is held by the cooling fan holding member 5 using metal fittings. At this time, the cooling fan 6 is held by the cooling fan holding member 5 so as to be housed in the cooling fan holding member 5 and the protrusion 5a. And LED1a is cooled by sending air to the inside of the cooling fan holding member 5 by rotation of a cooling fan.
The cooling fan holding member 5 has a protruding portion 5a inserted into the LED fixing member 2 and connected to the LED fixing member 2 using a connecting member 7 (connecting metal fitting).

定電流回路100は、定電流ダイオードを並列接続し、LED1aや冷却ファンに一定電流を安定的に供給するものである。定電流回路100は、LED固定部材2の内部に配置されている。   The constant current circuit 100 connects constant current diodes in parallel and stably supplies a constant current to the LED 1a and the cooling fan. The constant current circuit 100 is disposed inside the LED fixing member 2.

次に、LEDと冷却ファン、定電流回路の回路構成について図3を用いて説明する。LED1aを3個、直列接続し、LED群1を1組とする。このLED群1に抵抗4が直列接続されている。このLED群1と抵抗4とによりLED−抵抗組をなし、このLED−抵抗組を6組、並列接続する。さらに、冷却ファン6をLED−抵抗組に対して並列接続する。これらのLED1a、抵抗4、冷却ファン6は、定電流回路100に接続される形で1つの回路を構成する。   Next, the circuit configuration of the LED, the cooling fan, and the constant current circuit will be described with reference to FIG. Three LEDs 1a are connected in series, and LED group 1 is one set. A resistor 4 is connected to the LED group 1 in series. The LED group 1 and the resistor 4 form an LED-resistor group, and six LED-resistor groups are connected in parallel. Further, the cooling fan 6 is connected in parallel to the LED-resistor pair. The LED 1 a, the resistor 4, and the cooling fan 6 constitute one circuit by being connected to the constant current circuit 100.

車載バッテリー(図示しない)から供給される電流は、定電流回路100に流れ、その後、冷却ファン6、抵抗4、LED1aにそれぞれ電流が流れる。その後、定電流回路100を経由して、バッテリーに電流が戻る。   The current supplied from the in-vehicle battery (not shown) flows through the constant current circuit 100, and then the current flows through the cooling fan 6, the resistor 4, and the LED 1a. Thereafter, the current returns to the battery via the constant current circuit 100.

このように構成されたLED灯具について、一般車両に取り付け、5分間点灯を行う試験を行ったところ、LED温度が60〜80℃に抑えられ、ハイフラッシャー現象、ワーニング表示は生じなかった。その一方、冷却ファン6を設けなかったLED灯具について、5分間点灯を行う試験を行ったところ、LED温度が100℃を超え、4分後にはハイフラッシャー現象が発生した。
このように、本考案によれば、長時間シーケンシャル動作を行った場合でも、LED灯具の制御異常に起因するハイフラッシャー現象は発生しないことが確認できた。
About the LED lamp comprised in this way, when it attached to a general vehicle and the test which lighted for 5 minutes was done, LED temperature was suppressed to 60-80 degreeC, and the high flasher phenomenon and the warning display did not arise. On the other hand, an LED lamp that was not provided with the cooling fan 6 was tested for lighting for 5 minutes. As a result, the LED temperature exceeded 100 ° C., and a high flasher phenomenon occurred after 4 minutes.
As described above, according to the present invention, it has been confirmed that the high flasher phenomenon caused by the control abnormality of the LED lamp does not occur even when the sequential operation is performed for a long time.
