Description

本発明は、発光素子を用いた光源を含んで構成される車両用灯具の点灯制御技術に関する。 TECHNICAL FIELD The present invention relates to a lighting control technique for a vehicular lamp including a light source using a light emitting element.

近年、方向指示ランプ、制動ランプなどの車両用灯具として複数の発光素子を用いて構成したものが普及している。このような車両用灯具では、例えば、複数の発光素子を配列し、それらを時間差で順次点灯する制御（連鎖式点灯制御）を行うものもある。方向指示ランプを考えた場合、通常の動作モードでは、例えば毎分６０〜１２０回の速さで点滅するように点灯制御がなされる。また、この方向指示ランプにより緊急制動モードでの点滅を行わせる場合には、通常の動作時よりも速く、例えば毎分１８０〜３００回の速さで点滅させるように点灯制御がなされる。各動作モードにおける点滅速度は、例えば車両側から供給されるターン信号の周期に応じて定まる。 2. Description of the Related Art In recent years, as a vehicle lamp such as a direction indicator lamp and a braking lamp, a lamp including a plurality of light emitting elements has become widespread. In such a vehicular lamp, for example, a plurality of light emitting elements may be arranged and control for sequentially lighting them (chained lighting control) may be performed. Considering the direction indicator lamp, in a normal operation mode, lighting control is performed so as to blink at a speed of 60 to 120 times per minute, for example. Further, when the blinking in the emergency braking mode is performed by the direction indicator lamp, the lighting control is performed so as to blink at a speed of 180 to 300 times per minute, for example, faster than during normal operation. The blinking speed in each operation mode is determined, for example, according to the cycle of the turn signal supplied from the vehicle side.

ところで、方向指示ランプを通常の動作モードで動作させる場合には連鎖式点灯制御を行うことができるが、緊急制動モードで動作させる場合には連鎖式点灯制御を行うことが適さない場合がある。この場合、例えばターン信号の周期を検出し、その周期に応じて動作モードを切り換える必要がある。しかし、ターン信号の周期を検出するためには少なくとも半周期〜１周期分の信号の立ち上がりエッジ等を検出する必要があり、その間は緊急制動モードに切り替わらずに連鎖式点灯制御が行われるという不都合がある。 By the way, when the direction indicator lamp is operated in the normal operation mode, the chained lighting control can be performed, but when operated in the emergency braking mode, the chained lighting control may not be suitable. In this case, for example, it is necessary to detect the cycle of the turn signal and switch the operation mode according to the cycle. However, in order to detect the cycle of the turn signal, it is necessary to detect the rising edge of the signal for at least half cycle to one cycle, and during that time, the chain lighting control is performed without switching to the emergency braking mode. There is.

これに対して、特表２０１８−５０２０１３号公報（特許文献１）には、車両側からターン信号とは別途に与えられる緊急制動を示す信号であるディム信号が存在することを前提にして、当該ディム信号に基づいて動作モードを切り換える技術が記載されている。しかし、この場合にはディム信号という特別な信号の存在を前提としていることから、そのようなディム信号を供給しない車両には対応できないという点で汎用性に欠ける。 On the other hand, in Japanese Unexamined Patent Publication No. 2018-502013 (Patent Document 1), it is assumed that there is a dim signal that is a signal indicating emergency braking that is provided separately from the turn signal from the vehicle side, Techniques for switching operating modes based on dim signals are described. However, in this case, since it is premised on the presence of a special signal called a dim signal, it lacks versatility in that it cannot be applied to a vehicle that does not supply such a dim signal.

図１は、一実施形態の車両用灯具の全体構成を示すブロック図である。図示の車両用灯具は、一対のランプユニット１００Ｒ、１００Ｌを含んで構成されている。ランプユニット（第１ランプユニット）１００Ｒは、車両の後部右側の適宜位置に配置される。ランプユニット（第２ランプユニット）１００Ｌは、車両の後部左側の適宜位置に配置される。本実施形態の車両用灯具では、右方向へ移動する際の方向指示を行うためのターン信号である右側ターン信号（第１信号）２００Ｒと、左方向へ移動する際の方向指示を行うためのターン信号である左側ターン信号（第２信号）２００Ｌのそれぞれが図示しない車両から供給される。ここで、通常であれば、右側ターン信号２００Ｒは、ランプユニット１００Ｒのみに供給され、左側ターン信号２００Ｌは、ランプユニット１００Ｌのみに供給される。しかし、本実施形態では、配線部を用いて、右側ターン信号２００Ｒはランプユニット１００Ｒとランプユニット１００Ｌに分配され、左側ターン信号２００Ｌはランプユニット１００Ｌとランプユニット１００Ｒに分配されている。 FIG. 1 is a block diagram showing an overall configuration of a vehicle lamp according to an embodiment. The illustrated vehicle lamp includes a pair of lamp units 100R and 100L. The lamp unit (first lamp unit) 100R is disposed at an appropriate position on the rear right side of the vehicle. The lamp unit (second lamp unit) 100L is arranged at an appropriate position on the rear left side of the vehicle. In the vehicular lamp of the present embodiment, the right turn signal (first signal) 200R, which is a turn signal for instructing a direction when moving to the right, and the turn signal for instructing a direction when moving to the left. Each left turn signal (second signal) 200L, which is a turn signal, is supplied from a vehicle (not shown). Here, normally, the right turn signal 200R is supplied only to the lamp unit 100R, and the left turn signal 200L is supplied only to the lamp unit 100L. However, in the present embodiment, the right turn signal 200R is distributed to the lamp unit 100R and the lamp unit 100L and the left turn signal 200L is distributed to the lamp unit 100L and the lamp unit 100R by using the wiring portion.

図２は、ランプユニットの詳細な構成を示す回路図である。なお、ここではランプユニット１００Ｒについて示すが、ランプユニット１００Ｌについてもターン信号の位置が入れ替わるのみで構成は同様である。ランプユニット１００Ｒは、複数のＬＥＤ（発光素子）１〜６、複数の定電流回路１１〜１６、電源回路２１、連鎖式点灯制御回路２２、非連鎖式点灯制御回路２３、複数のダイオード４１〜４６、５２〜５６を含んで構成されている。 FIG. 2 is a circuit diagram showing a detailed configuration of the lamp unit. Although the lamp unit 100R is shown here, the configuration of the lamp unit 100L is similar except that the positions of the turn signals are exchanged. The lamp unit 100R includes a plurality of LEDs (light emitting elements) 1 to 6, a plurality of constant current circuits 11 to 16, a power supply circuit 21, a chained lighting control circuit 22, a non-chained lighting control circuit 23, and a plurality of diodes 41 to 46. 52 to 56 are included.

なお、複数の定電流回路１１〜１６、電源回路２１、連鎖式点灯制御回路２２、非連鎖式点灯制御回路２３、複数のダイオード４１〜４６、５２〜５６が「点灯制御装置」に対応している。また、ランプユニット１００Ｒに含まれる複数の定電流回路１１〜１６、電源回路２１、連鎖式点灯制御回路２２、非連鎖式点灯制御回路２３が「第１制御部」に対応し、ランプユニット１００Ｌに含まれる複数の定電流回路１１〜１６、電源回路２１、連鎖式点灯制御回路２２、非連鎖式点灯制御回路２３が「第２制御部」に対応している。また、ランプユニット１００Ｒに含まれる連鎖式点灯制御回路２２が「第１順次点灯駆動回路」に対応し、非連鎖式点灯制御回路２３が「第１同時点灯駆動回路」に対応する。また、ランプユニット１００Ｌに含まれる連鎖式点灯制御回路２２が「第２順次点灯駆動回路」に対応し、非連鎖式点灯制御回路２３が「第２同時点灯駆動回路」に対応する。 The plurality of constant current circuits 11 to 16, the power supply circuit 21, the chained lighting control circuit 22, the non-chained lighting control circuit 23, and the plurality of diodes 41 to 46, 52 to 56 correspond to the “lighting control device”. There is. Further, the plurality of constant current circuits 11 to 16, the power supply circuit 21, the chained lighting control circuit 22, and the unchained lighting control circuit 23 included in the lamp unit 100R correspond to the “first control unit”, and are included in the lamp unit 100L. The plurality of constant current circuits 11 to 16, the power supply circuit 21, the chained lighting control circuit 22 and the non-chained lighting control circuit 23 included therein correspond to the “second control unit”. The chained lighting control circuit 22 included in the lamp unit 100R corresponds to the "first sequential lighting drive circuit", and the non-chained lighting control circuit 23 corresponds to the "first simultaneous lighting drive circuit". The chained lighting control circuit 22 included in the lamp unit 100L corresponds to the “second sequential lighting drive circuit”, and the non-chained lighting control circuit 23 corresponds to the “second simultaneous lighting drive circuit”.

各ＬＥＤ１〜６は、各々に接続された定電流回路１１〜１６によって供給される電流により発光する。 Each of the LEDs 1 to 6 emits light by the current supplied by the constant current circuits 11 to 16 connected thereto.

各定電流回路１１〜１６は、電源回路２１から電力（電源電圧）の供給を受けて定電流を発生させて、各々に対応づけられて接続されたＬＥＤ１〜６へ電流を供給する。 Each of the constant current circuits 11 to 16 is supplied with electric power (power supply voltage) from the power supply circuit 21 to generate a constant current, and supplies the current to the LEDs 1 to 6 which are associated with each other.

電源回路２１は、電圧信号である右側ターン信号２００Ｒの入力を受けて、各定電流回路１１〜１６、連鎖式点灯制御回路２２、非連鎖式点灯制御回路２３の動作に必要な電圧を発生させて当該電圧を各々へ供給する。この電源回路２１は、例えばＤＣ−ＤＣコンバータを含んで構成されている。 The power supply circuit 21 receives the right turn signal 200R, which is a voltage signal, and generates a voltage required for the operation of each of the constant current circuits 11 to 16, the chained lighting control circuit 22, and the unchained lighting control circuit 23. And supply the voltage to each. The power supply circuit 21 is configured to include, for example, a DC-DC converter.

連鎖式点灯制御回路２２は、各ＬＥＤ１〜６を順次点灯させるための制御を行う。具体的には、連鎖式点灯制御回路２２は、電源回路２１から電圧が供給されると動作し、各定電流回路１１〜１６を時間差で順次動作させる制御を行う。これにより、定電流回路１１〜１６からは時間差で各ＬＥＤ１〜６に電流が供給され、その結果、各ＬＥＤ１〜６が時間差で点灯する。本実施形態では、ＬＥＤ１、ＬＥＤ２、・・・ＬＥＤ６の順番で連鎖式に点灯するものとする。電源回路２１からの電圧供給が停止するとこの連鎖式点灯制御回路２２の動作も停止し、それにより各ＬＥＤ１〜６も消灯する。 The chained lighting control circuit 22 performs control for sequentially lighting the LEDs 1 to 6. Specifically, the chained lighting control circuit 22 operates when a voltage is supplied from the power supply circuit 21, and controls the constant current circuits 11 to 16 to operate sequentially with a time difference. As a result, current is supplied from the constant current circuits 11 to 16 to the LEDs 1 to 6 with a time difference, and as a result, the LEDs 1 to 6 are turned on with a time difference. In the present embodiment, it is assumed that LEDs 1, LED 2,... When the voltage supply from the power supply circuit 21 is stopped, the operation of the chain type lighting control circuit 22 is also stopped, whereby the LEDs 1 to 6 are also turned off.

非連鎖式点灯制御回路２３は、各ＬＥＤ１〜６を同時点灯させるための制御を行う。具体的には、非連鎖式制御回路２３は、電源回路２１から電圧が供給され、かつ左側ターン信号２００Ｌが供給されると動作し、各定電流回路１１〜１６を実質的に同時に動作させる制御を行う。これにより、これにより、定電流回路１１〜１６からは実質的に同時に各ＬＥＤ１〜６に電流が供給され、その結果、各ＬＥＤ１〜６が実質的に同時に点灯する。電源回路２１からの電圧供給が停止するとこの非連鎖式点灯制御回路２３の動作も停止し、それにより各ＬＥＤ１〜６も消灯する。 The unchained lighting control circuit 23 performs control for simultaneously lighting the LEDs 1 to 6. Specifically, the unchained control circuit 23 operates when the voltage is supplied from the power supply circuit 21 and the left turn signal 200L is supplied, and the constant current circuits 11 to 16 are operated substantially simultaneously. I do. As a result, the current is supplied from the constant current circuits 11 to 16 to the LEDs 1 to 6 at substantially the same time, and as a result, the LEDs 1 to 6 are turned on at substantially the same time. When the voltage supply from the power supply circuit 21 is stopped, the operation of the non-chaining type lighting control circuit 23 is also stopped, whereby the LEDs 1 to 6 are also turned off.

各ダイオード４１〜４６は、それぞれ定電流回路１１〜１６と連鎖式点灯制御回路２２との間に接続されている。同様に、各ダイオード５２〜５６は、それぞれ定電流回路１１〜１６と非連鎖式点灯制御回路２３との間に接続されている。これらは、連鎖式点灯制御回路２２や非連鎖式点灯制御回路２３への逆電圧印加を防止するための逆接ダイオードである。 The diodes 41 to 46 are connected between the constant current circuits 11 to 16 and the chain type lighting control circuit 22, respectively. Similarly, the diodes 52 to 56 are respectively connected between the constant current circuits 11 to 16 and the unchained lighting control circuit 23. These are reverse connection diodes for preventing reverse voltage application to the chain lighting control circuit 22 and the non-chain lighting control circuit 23.

図３は、ランプユニットの動作を説明するためのタイミングチャートである。ここでは、ランプユニット１００Ｒの動作を説明するため、「ターン信号」が右側ターン信号２００Ｒに対応し、「反対側ランプのターン信号」が左側ターン信号２００Ｌに対応するものとする。なお、ランプユニット１００Ｌの場合には上記の関係が入れ替わり、「ターン信号」が左側ターン信号２００Ｌに対応し、「反対側ランプのターン信号」が右側ターン信号２００Ｒに対応する。 FIG. 3 is a timing chart for explaining the operation of the lamp unit. Here, in order to explain the operation of the lamp unit 100R, it is assumed that the "turn signal" corresponds to the right turn signal 200R and the "opposite lamp turn signal" corresponds to the left turn signal 200L. In the case of the lamp unit 100L, the above relationships are interchanged, and the "turn signal" corresponds to the left turn signal 200L and the "opposite lamp turn signal" corresponds to the right turn signal 200R.

通常の動作モードでは、右側ターン信号２００Ｒと左側ターン信号２００Ｌは、いずれか一方のみがパルス状に変化し、他方は、例えば０ボルト（オフ状態）になる。ここでは、車両の方向指示レバーが「右折」に操作され、それに対応して所定周期の右側ターン信号２００Ｒがランプユニット１００Ｒへ与えられるものとする。このときには、ＬＥＤ１〜６は、連鎖式点灯制御回路２２に制御されて、時間差で順次点灯（ＯＮ）となり、同じタイミングで消灯（ＯＦＦ）になるという動作を繰り返す。 In the normal operation mode, only one of the right turn signal 200R and the left turn signal 200L changes in a pulse shape, and the other turns to, for example, 0 volt (off state). Here, it is assumed that the direction indicating lever of the vehicle is operated to "turn right" and the right turn signal 200R of a predetermined cycle is given to the lamp unit 100R correspondingly. At this time, the LEDs 1 to 6 are controlled by the chained lighting control circuit 22 to be sequentially turned on (ON) with a time difference and turned off (OFF) at the same timing, which is repeated.

次に、車両において急ブレーキが踏まれる等により緊急制動モード（緊急制動表示灯）になると、車両からは通常の動作モードよりも周期を短く設定した右側ターン信号２００Ｒおよび左側ターン信号２００Ｌが同期して与えられる。このときには、左側ターン信号２００Ｌに応じて非連鎖式点灯制御回路２３が動作することにより、各ＬＥＤ１〜６が実質的に右側ターン信号２００Ｒの周期と同じタイミングで点消灯を繰り返す。 Next, when the vehicle enters an emergency braking mode (emergency braking indicator light) due to sudden braking, etc., the vehicle synchronizes the right turn signal 200R and the left turn signal 200L with a shorter cycle than the normal operation mode. Given. At this time, the unchained lighting control circuit 23 operates in response to the left turn signal 200L, so that the LEDs 1 to 6 are repeatedly turned on and off at substantially the same timing as the cycle of the right turn signal 200R.

なお、車両においてハザードランプのボタンが操作された場合も同様である。具体的には、通常の動作モードと同周期の右側ターン信号２００Ｒおよび左側ターン信号２００Ｌが同期して与えられる。このときには、左側ターン信号２００Ｌに応じて非連鎖式点灯制御回路２３が動作することにより、各ＬＥＤ１〜６が実質的に右側ターン信号２００Ｒの周期と同じタイミングで点消灯を繰り返す。 The same applies when the button of the hazard lamp is operated in the vehicle. Specifically, the right turn signal 200R and the left turn signal 200L having the same cycle as the normal operation mode are applied in synchronization. At this time, the unchained lighting control circuit 23 operates according to the left turn signal 200L, so that each of the LEDs 1 to 6 repeats lighting and extinction substantially at the same timing as the cycle of the right turn signal 200R.

以上のような実施形態によれば、特別な信号を必要とせず、通常用意されていると考えられる左右の各ターン信号を用いて、連鎖式点灯制御を行う方向指示ランプを緊急制動ランプとしても動作させることが可能となる。 According to the embodiment as described above, no special signal is required, and the left and right turn signals that are considered to be normally prepared are used, and the direction indicator lamp for performing chained lighting control may be used as an emergency braking lamp. It becomes possible to operate.
