Description

The present invention relates to an in-vehicle illuminating device, and more particularly to an in-vehicle illuminating device in which turning on and off of an LED as a light source is controlled in accordance with presence or absence of vibration of a vehicle body or a change in the magnitude of the vibration.

In-vehicle lighting systems include headlights, tail lights, interior lights, etc., which are standard equipment on vehicles, and lighting systems (auxiliary lighting systems) that are installed by the user. It can be used for various purposes depending on the will of the person.

By the way, recently, as a safety measure mainly for business vehicles such as taxis, it is common practice to inform oncoming vehicles and pedestrians etc. of their own vehicles by driving while the lights are on in bright daylight. In that case, the lighting was done by turning on the standard headlights.

In addition, when a user installs an auxiliary lighting device in a car, the user often selects a cigarette lighter socket installed in the car in advance as a place to secure the power supply. It can be said that such an auxiliary lighting device has an advantage that it is easy to install for a user.

As described above, when taking safety measures such as driving with the lights on during the day, if the standard headlights are used as the lighting, the operation of turning on and off the standard headlights will be tail lights and indoor lighting. Because the backlight of the instruments is turned on and off, when the headlight is turned on, the taillight and the backlight are turned on unnecessarily, and the load applied to the vehicle battery increases. Also, since the headlights are turned on and off in the driver's seat of the car because it is bright in the daytime, it is possible to check from the driver's seat whether the headlights were actually turned on or not. Due to the difficulty, or even if lighting or turning off can be confirmed from the driver's seat, it is not possible to completely avoid a situation where the driver forgets to turn on or off.

In addition, a standard headlight is connected to the vehicle's on-board battery, that is, the on-board battery for obtaining engine starting power, by an electric cord, and a switch for controlling the turning on and off of the headlight alone is separately provided in the electric cord. It is conceivable that the driver operates the switch to turn on and off only the headlight.However, in this case, the situation in which the taillight and backlight are turned on and off together with the headlight is avoided. Even if the load on the battery can be reduced, it is not possible to completely prevent the driver from forgetting to turn on or off the headlight.

Further, when an auxiliary lighting device using the cigarette lighter socket as a power supply is installed, the cigarette lighter socket is used exclusively for the power supply of the auxiliary lighter, so that it is difficult to use it for other purposes. .

The present invention has been made under the above circumstances, and automatically turns on and off a lighting device as a light source by detecting the presence or absence of vibration of a vehicle body or a change in the magnitude of vibration of the vehicle body. By doing so, even in bright daylight, the lighting equipment is always turned on when the car that needs lighting is running, and the lighting equipment is always turned off when the car is stopped and no lighting is needed. It is an object of the present invention to provide an in-vehicle lighting device capable of producing a vehicle.

Another object of the present invention is to provide an in-vehicle lighting device that is useful for preventing so-called vandalism and theft of a car.

Still another object of the present invention is to provide an in-vehicle lighting device that can reduce the load on an in-vehicle battery.

Further, an object of the present invention is to provide an in-vehicle lighting device that is easy to install while selecting an in-vehicle battery as a power source.

The vehicle lighting device according to the present invention is a vehicle lighting device in which a lighting device having a built-in LED as a light source is connected to a power supply by an electric cord, and a switch for turning on and off the light source is interposed in the electric cord. In the above, the switch has a built-in vibration sensor that detects the presence or absence of vibration of the vehicle body or a change in the magnitude of vibration of the vehicle body and outputs a detection signal, and ON and OFF are controlled by the detection signal of the vibration sensor. It is a switch with a built-in vibration sensor.

With this configuration, the switch is turned ON and OFF not by the driver's operation in the driver's seat of the car, but by the presence or absence of vibration of the vehicle body or the change in the magnitude of the vibration of the vehicle body. There is no need for the user to perform an operation for turning on and off the lighting equipment. Also, when there is vibration of the vehicle body, or when the vibration of the vehicle body becomes large, the switch is switched from OFF to ON and the lighting device is turned on, and when there is no vibration of the vehicle body, or the vibration of the vehicle body becomes small. It is possible to switch the switch from ON to OFF and turn off the lighting when the vehicle is turned on, so that when the car engine is started or the car is running, It is possible to perform control such that the lighting device is always turned on and the lighting device is always turned off when the vehicle engine is stopped or when the vehicle is stopped. For security purposes, it is also possible to perform control such that the lighting device is turned on when the vehicle body starts to vibrate. Further, in the vehicle-mounted lighting device, since the LED is used as the light source of the lighting device, there is an advantage that the power consumption at the time of lighting can be reduced.

In the present invention, the switch with built-in vibration sensor is immediately switched from OFF to ON by a detection signal output when the vibration sensor detects the occurrence of vibration of the vehicle body accompanying the start of the engine of the vehicle, and After detecting the stop of the vibration of the vehicle body due to the stop and outputting the detection signal, the switch may be switched from ON to OFF after a predetermined time. According to this, when the vehicle body starts to vibrate due to the driver starting the engine in the driver's seat, the switch with built-in vibration sensor is immediately switched from OFF to ON, and the lighting device is turned on. The lighting fixture remains lit. When the engine is stopped immediately after the engine is started, for example, when the engine is restarted immediately after the engine has failed to start, the vibration of the vehicle body at the time of the first engine start operation may cause the lighting to stop. Even if the lighting is turned on and the vibration of the vehicle body stops due to engine start failure, the lighting fixture remains lit for a certain period of time, so if the next engine start operation is performed within that fixed time, Keeps lighting without turning off the lighting.

で は In the present invention, it is preferable that the electric cord has a connection terminal that can be directly connected to a terminal of the vehicle-mounted battery. With this configuration, the user can use the in-vehicle battery for starting the engine as a power source without using the indoor cigar socket as a power source. Moreover, since the electric cord has a connection terminal that can be directly connected to the terminal of the vehicle battery, anyone can perform the work of connecting the electric cord to the terminal of the vehicle battery without any special skills. In addition, installation of the on-vehicle lighting device is easy.

で は In the present invention, an in-vehicle battery or a dry cell can be used as the power source. In addition, even if the vehicle-mounted battery or the dry battery is used as the power source, since the light source with low power consumption such as the LED is used, there is an advantage that an unreasonable load is not applied to the vehicle-mounted battery or the dry battery.

As described above, according to the present invention, the presence or absence of vibration of the vehicle body or a change in the magnitude of the vibration of the vehicle body is sensed, and the lighting device as a light source is automatically turned on and off. In a case where the vehicle is driven with the lighting turned on in a bright daytime, it is possible to completely avoid a situation where the driver forgets to turn on or turn off the light, thereby reducing the burden on the driver. In addition, even if the car body accidentally vibrates due to vandalism while the car is stopped at night, it can be notified by lighting the lighting equipment, so it can be used for crime prevention. is there. In addition, if the LED is used as the light source to reduce the power consumption during lighting, or if a terminal that allows the electric cord to be easily connected to the vehicle battery is provided, the load of the power source such as the vehicle battery or dry battery Is reduced, and a reduction in the service life thereof is suppressed, and an effect that the installation becomes easy and anyone can easily install the auxiliary lighting device as an auxiliary lighting device is exhibited.

FIG. 1 is a schematic configuration diagram of a vehicle lighting device according to the present invention, and FIG.

に お い て In FIG. 1, reference numeral 1 denotes a lighting device, 2 denotes a switch, and 3 denotes an electric cord for connecting the lighting device 1 to a power supply 4.

As shown in FIG. 2, the lighting fixture 1 has a plurality of LEDs (for example, white light emitting diodes) as the light source 14 and the light source 14 mounted inside a case 11 formed by combining a case body 12 and a cover 13. It has a built-in wiring board 15, a first lens 16 disposed in front of the light source 14, and a second lens 17 in front of the first lens 16. Reference numeral 18 denotes a frame for fixing the light source 14 at a predetermined position inside the case 11. Then, the case 11 is swingably connected around the shaft 53 via a shaft 53 to a mounting tool 5 having a mounting surface 52 holding an adhesive 51. The lighting fixture 1 is attached by attaching an adhesive 51 to a desired portion of a member to be attached, such as a body panel of an automobile, by attaching an attachment surface 52 of the attachment 5 to a shaft body. By swinging the case 11 around 53, the direction of light irradiation can be changed.

The switch 2 has a built-in vibration sensor (not shown) in the case. When the vibration sensor detects the presence or absence of vibration or a change in the magnitude of the vibration and outputs a detection signal, the switch 2 turns ON and OFF according to the detection signal. Consists of a switch with a built-in vibration sensor. In other words, the vibration sensor has a high sensitivity mode in which the sensitivity is adjusted to sense the vibration when the vibration occurs and immediately outputs a sensing signal, and a magnitude (for example, amplitude and frequency) of the vibration. A sensor which does not output a sensing signal until a certain value reaches a certain value, and which can select a low sensitivity mode in which a sensing signal is output when the magnitude of the vibration exceeds a certain value is used. Further, a timer circuit is interposed between the sensing signal output terminal of the vibration sensor and the input terminal of the switching mechanism, and the switching mechanism is immediately turned on when the vibration sensor outputs a sensing signal by a mode switching operation of the timer circuit. Or a vibration sensing output non-delay mode in which the switching mechanism is switched off, and a vibration sensing output delay mode in which the switching mechanism is switched on and off after a certain period of time after the vibration sensor outputs the sensing signal. The non-vibration non-delay mode switches the ON / OFF of the switching mechanism as soon as the sensing signal is no longer output, and the ON / OFF of the switching mechanism after a fixed time after the sensing signal of the vibration sensor is no longer output. It is possible to select a vibration damping delay mode.

In this embodiment, the vibration sensor incorporated in the switch 2 is set to a low sensitivity mode in which a vibration signal of the vehicle body generated when the engine of the automobile is started is detected and a sensing signal is output. Are set to the vibration sensing non-delay mode and the vibration damping delay mode. The switching mechanism switches from OFF to ON as the vibration sensor detects the vibration and outputs a detection signal, and the vibration sensor outputs a detection signal when the vibration sensor detects the stop of the vibration of the vehicle body due to the engine stop. As a result, the state is switched from ON to OFF. Further, the delay time of the timer circuit set in the vibration damping delay mode is set to about 15 to 20 seconds.

As shown in FIG. 1, the switch 2 is interposed in an electric cord 3 for connecting the lighting device 1 and a power supply 4, and two lighting devices 1 and 1 are connected to the switch 2 in parallel. I have. Further, at the end of the electric cord 3, connection terminals 31 and 32 called U-shaped fittings are provided, and the connection terminals 31 and 32 are used for starting the engine. And the minus terminal b can be directly connected to each other. When the connection terminals 31 and 32 are directly connected to the plus terminal a and the minus terminal b of the vehicle-mounted battery 4 respectively, the switch When the switch 2 is switched from OFF to ON, the light source 14 of the lighting fixture 1 is turned on by the power of the vehicle-mounted battery 4, and the light source 14 of the lighting fixture 1 is turned off when the switch 2 is switched from ON to OFF. Has become. In the illustrated example, the connector 33 is interposed between the lighting device 1 and the switch 2 of the electric cord 3 so that the lighting device 1 can be easily connected to the electric cord 3. An overcurrent is prevented from flowing by interposing a fuse 35 at a location between the connection terminal 31.

In the vehicle lighting device described above, the connection of the connection terminals 31 and 32 at the end of the electric cord 3 to the plus terminal a and the minus terminal b of the vehicle battery 4 is directly connected to each other. Is installed at an appropriate position of the vehicle body panel, for example, beside or below the headlight, and the electric cord is routed by using a gap in the vehicle body panel or the like to complete the installation. Since such an installation work can be performed by anyone without requiring special skills, it can be easily performed even if the user of the vehicle does not know the structure of the vehicle.

In addition, in a vehicle equipped with an on-vehicle lighting device, when a driver performs an engine start operation in a driver's seat, the vehicle body vibrates with the start of the engine. And outputs a sensing signal, and the switching mechanism of the switch 2 is immediately switched from OFF to ON by the sensing signal, and the lighting device 1 is turned on. Also, the lighting fixture 1 remains lit. For this reason, the driver need only perform the engine start operation indispensable for running the automobile, and does not need to perform the operation of turning on the lighting device 1 in particular. This makes it possible to completely avoid a situation in which the driver forgets to turn on the light when driving while the light is on in the bright daytime. Also, even if the car body accidentally vibrates due to vandalism while the car is stopped at night, if the magnitude of the vibration is about the same as the magnitude of the vibration caused by starting the engine, this is indicated by lighting equipment. Since it can be notified by lighting of 1, it is also useful for crime prevention.

On the other hand, when the vehicle is stopped and the engine is stopped after the vehicle is driven with the lighting device 1 turned on, the vehicle body does not vibrate due to the stop of the engine. In this case, according to the on-vehicle lighting device of the embodiment, the vibration sensor included in the switch 2 detects the stop of the vibration of the vehicle body due to the stop of the engine, outputs a detection signal, and is set to the vibration damping delay mode. The switching mechanism switches from ON to OFF after a predetermined time, for example, 15 to 20 seconds from the stop of the vibration of the vehicle body due to the operation of the timer circuit, and the lighting device 1 is turned off. Therefore, even in a bright daytime, the situation where the lighting fixture 1 remains lit can be reliably prevented.

Further, as in the vehicle-mounted lighting device according to the embodiment, the switching mechanism is switched from ON to OFF after a predetermined time, for example, 15 to 20 seconds after the vibration of the vehicle body is stopped by the action of the timer circuit set in the vibration damping delay mode. On the other hand, if the control of turning off the lighting device 1 is performed, the lighting device is turned on by the vibration of the vehicle body at the time of the first engine starting operation in a case where the engine start operation is immediately restarted after the engine has failed. However, even if the vibration of the vehicle body stops due to the failure of the engine start, the lighting device remains lit for a certain period of time, so if the next engine start operation is performed within the certain period, the lighting The tool stays on without going off.

In addition, according to this embodiment, in addition to avoiding the situation where the taillight and the backlight are turned on and off together with the headlight, the LED with low power consumption is used as the light source, so that the load on the battery is small. Can be suppressed. In addition, since the cigarette lighter socket is not used as a power source, there is an advantage that the cigarette lighter socket can be used for other purposes.

In this embodiment, an example in which an in-vehicle battery is used as a power source has been described. However, a dry battery can be used as the power source, and when the dry battery is used, the electric cord 3 needs to be routed in the engine room of the automobile. There is no advantage.

FIG. 2 is a schematic configuration diagram of the vehicle lighting device according to the present invention. It is sectional drawing of a lighting fixture.
