Description

Vehicle display device including light emitting diode vehicle indicator and vehicle having same {Vehicle Indication Device comprising LED lamp and Vehicle having such Device}

The present invention provides a vehicle display device having a light emitting diode type vehicle indicator and a vehicle including the light emitting diode type vehicle indicator. A vehicle display device capable of preventing an accident and a vehicle having the same.

Vehicles such as passenger cars, vans, and vans are generally equipped with up and down headlights, vehicle headlights (or taillights), turn indicators, brake lights, fog lights, and the like. It is provided inside. That is, the left side of the vehicle steering wheel is provided with a combination switch that enables the headlights to be turned on and off, the up and down adjustment, and the tail light and the turn signal on. In addition, the brake light is automatically turned on when the brake is detected to operate.

FIG. 1 shows the types and positions of lamps provided in such a vehicle. The vehicle is provided with up and down headlights 11 on the left and right sides of the vehicle front part, and taillights and direction indicators 12 are provided together with the headlights. have. In addition, one or more fog lights 13 may be provided below the headlamp. In addition, the rear left and right sides of the vehicle are provided with one taillight, a direction indicator light and a brake light (indicated by 14 in total).

However, the lamps of all vehicles except the brake light only light when the user activates the switch.

Accordingly, there have been many cases in which a user is inadvertently operated without turning on a headlight or a taillight at night and leads to a large accident without being identified by another vehicle.

In addition, in order to reduce traffic accidents, it is often recommended to turn on the headlights in recent days. In fact, some developed countries have mandated daytime headlights to prevent traffic accidents, and a number of experiments have demonstrated that traffic accidents are dramatically reduced when the headlights are turned on during the day.

However, during the day, the user hardly feels the need to turn on the headlight, so not only does the headlight actually turn on, but even if the headlight is turned on during driving, the user does not recognize the fact and frequently discharges the battery by leaving it as it is. There was a problem.

In addition, since the headlight consumes a relatively large amount of power and the life of the headlamp lamp is limited to about 5000 hours, the headlight lamp not only shortens the life of the battery when it is lit until the day, but also causes inconvenience in that the headlamp lamp needs to be replaced frequently. Headlight lighting is hardly achieved.

The present invention focuses on this point, and the vehicle display that can prevent accidents by automatically lighting a separate low-power and long-life vehicle indicator when the vehicle is started regardless of day or night and displaying the vehicle outside. It is to provide a device.

It is an object of the present invention to provide a vehicle display device having a vehicle indicator and a vehicle including the same, which is mounted on the outside of the vehicle and is automatically turned on at the same time as the vehicle is started and automatically turned off when the vehicle is turned off.

Another object of the present invention is to provide a vehicle display apparatus having a low power and long life light emitting diode-type vehicle indicator operated by starting the vehicle and a vehicle equipped with the same.

It is still another object of the present invention to provide a vehicle display apparatus having a vehicle indicator including a plurality of light emitting diodes operating according to vehicle startup, and a vehicle equipped with the vehicle.

The vehicle indicator may be configured by arranging one or more electronic light emitting devices, such as one or more light emitting diodes (LEDs), in a matrix form, but may be implemented with only one light emitting diode if it has sufficient brightness or luminance.

Start detection unit for automatically detecting the start of the vehicle, the mechanical switch provided in the car key assembly, the rotation sensor for detecting the rotation of the engine, the current / voltage sensor for detecting the starting current discharge of the battery, the vibration of the vehicle It may be made of a sensor unit consisting of one or more of the vibration sensor to check whether the start, and a signal transmission unit for transmitting a start start signal or a start end signal from the sensor unit to the lighting relay unit.

The lighting relay unit receives a start start signal or a start end signal from the start detection unit, and functions to interrupt a current between the vehicle indicator and the vehicle power source.

By using such a vehicle display device, even if the user does not perform a special operation, regardless of the day and night, the vehicle lights up the high-brightness of the vehicle at low power consumption at all times while driving, thereby reducing the possibility of an accident.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Figure 2 is a block diagram showing the configuration of a vehicle display device according to the present invention for each function.

Vehicle display device according to the present invention is a vehicle indicator (20, 20 ') consisting of one or more light emitting diode elements mounted on an external part of the vehicle, the start detection unit 30 and the start detection unit for detecting whether the vehicle is started Receiving the start detection signal in the start of the start of the vehicle indicator light is turned on, and when the start of the vehicle comprises a light relay unit 40 for turning off the vehicle indicator.

Light emitting diodes (“LEDs”) are devices that use light emitting phenomena generated when a voltage is applied to a semiconductor, and are commonly used for indicators and numeric displays of general electronic devices.

When the LED is forwarded to the semiconductor of a specific element, electrons and holes move through the semiconductor junction and recombine with each other.The recombination produces less energy than when the electrons and holes are separated. It uses the principle of emitting light. The chip that emits light is typically 0.25 mm2, which is very small, and the size of the LED is determined by the plastic lens and leadframe.

As for the color of light emitted from the LED, the composition of the semiconductor chip components creates a unique wavelength, which determines the color of the light.

AlGaInP chip, InGaN chip, etc. may be used for the high-brightness LED used in the present invention. Since LEDs have high light conversion efficiency, the power consumption required to produce the same brightness of illumination is very small as 1/8 of the bulbs and 1/2 of the fluorescent lamps, and since the LEDs are small light sources, they can be miniaturized, thinned, and light. . In addition, the lifespan of a general automotive lamp is 1,000 to 10,000 hours, whereas the LED is usually semi-permanent because it has a long life of more than 1 million hours.

In addition, since it is not thermally discharged light, the preheating time is unnecessary, the lighting and extinguishing speed is very fast, and there is an environment-friendly advantage because it does not use a gas for discharge such as mercury lamp used in fluorescent lamps.

In addition, the use of LED as a display device of the vehicle can prevent the so-called Sun Phantom phenomenon, in which the sunlight is reflected on the lens surface when the sunlight is strong during the day, making it impossible to check whether the lamp is turned on or off. As a result, the vehicle's discrimination ability can be further improved than when the conventional headlight is used as the daylight indicator.

The vehicle indicator of the present invention can be implemented to have the brightness or luminance (about 600 to 1000 lm) required for identification of the vehicle by placing a plurality of LEDs having a luminous flux of 5 lm (lumen) / watt or more in a plane. Of course, if only one high-brightness LED can secure sufficient luminous flux or luminance, it may be implemented with only one or a few few LEDs. Specific forms and attachment positions of the vehicle indicator will be described in more detail below with reference to FIGS. 3 and 4.

Start detection unit 30 is to automatically detect the start of the vehicle, it may be composed of a detection sensor unit for detecting whether the start is stuck and a signal transmission unit for transmitting the start start signal or start end signal from the west to the lighting relay unit. have.

The sensor unit can be used in any manner as long as it can detect starting, for example, a mechanical switch (or ignition ignition switch 31) provided in the car key assembly, an RPM sensor and a speedometer for detecting engine rotation. The rotation sensor 32, a current / voltage sensor 33 for detecting a starting current discharge of the battery, a vibration sensor 34 for detecting whether the vehicle is started by detecting vibration of the vehicle, and the like may be used.

The mechanical switch may be configured to detect (eg, use an ignition power switch) the start key signal or the start end signal in the automotive key assembly to detect that the key is rotating in Start mode and thus rotate The sensor may be configured as a plug ignition check sensor for checking the RPM of the engine or a wheel drive sensor for checking the rotation of the wheel, a speedometer, a crank angle sensor for detecting the engine speed by detecting a drive plate.

Sensors for detecting such engine or wheel rotation are disclosed in a number of designs, including Korean Patent Publication No. 1998-062252, and detailed descriptions thereof will be omitted.

The current / voltage sensor generates a spark discharge to the spark plug according to the mode state of the ignition switch (IGN), so that the current of the ignition coil (C) is boosted to a high voltage current and supplied to the distributor to burn the mixer compressed in the combustion chamber. Or by monitoring voltage changes. In other words, if a high current flows suddenly in the ignition coil, a start start signal may be generated, and a start end signal may be detected by generating a start end signal when no current flows in the ignition coil for a predetermined time.

The vibration sensor detects a vibration state of the vehicle body and determines that the engine is started when a certain amount of vibration is exceeded for a predetermined period of time, and generates a start signal. Can be implemented to occur.

Of course, such a start detection unit may be used in any way other than the above-described manner, and there is no limitation in the way as long as it can accurately determine whether the start.

The lighting relay unit 40 may receive a start start signal or a start end signal from the start detection unit and control the supply of current flowing into the vehicle indicator according to the present invention.

The lighting relay unit 40 may be simply configured as shown in FIG. 5. When the start relay unit 40 receives a start start signal, that is, a high voltage signal from the start detection unit, the lighting relay unit 40 is kept ON and starts from the start detection unit. That is, the switch includes a switch that is turned off when a low voltage signal is input, and the switch includes a + terminal (B +) and a fuse and a vehicle indicator of the battery of the vehicle. It can be configured as a part in a closed circuit connected in series up to-). Looking at the operation state of the lighting relay, when the start-up signal is first received from the start detection unit, the switch is turned on, and current flows from the + terminal of the battery to the vehicle indicator to light up the indicator. As mentioned above, the switch remains on until the start end signal is received, and the start of the vehicle turns off when the start signal is received.

However, the lighting relay unit 40 is not necessarily limited to this configuration, it may be implemented as a relay using an excitation coil or the like or may be implemented in other ways.

In addition, in the present specification, the start detection unit and the lighting relay unit are separately described for convenience, but may be integrated and implemented if necessary. For example, the vehicle indicator may be simply mounted on the outside of the vehicle after the vehicle is shipped, and both terminals of the vehicle indicator may be disposed between the + terminal of the battery and the ground, and the ignition power switch may be implemented as the intermediate switch. In this case, the ignition power switch serves as both a start detection unit and a lighting relay unit.

3 shows an example of a vehicle equipped with a vehicle display device according to an embodiment of the present invention.

The vehicle indicators 20 and 20 'according to the present invention can be mounted anywhere outside the vehicle, but the purpose is to inform the driver or pedestrian of another vehicle of the vehicle's existence and position, as shown in FIG. 3A. The headlamps may be located below or above the headlamps, or may be located directly above the brake lights of FIG. 3B and the rear of the vehicle body, but are not limited thereto. In addition, the vehicle may be mounted at any position to facilitate identification of the vehicle, such as the side of the vehicle body, the rear mirror, the driver's seat, the rear brake, and the like. In addition, a plurality of vehicle indicators may be mounted at one or more positions.

If necessary, blue, red, yellow, etc. can be given to the vehicle lights in order to enhance the identification of the vehicle lights, and similarly to warning lights, they can be configured to blink every predetermined period. One or more vehicle indicators may be lit at the intersection at predetermined intervals. In addition, other forms or lighting methods suitable for the purpose of enhancing the identification of the vehicle indicator may be adopted.

In addition, if necessary, by using a sensor to measure the ambient brightness, when the surroundings are bright, such as during good daytime weather, or when it is raining or cloudy, the voltage applied to the LED is increased to maintain high brightness, and at night However, indoors you may want to adjust to maintain low light intensity.

To this end, the vehicle display device according to the present invention may further include a light sensor that can sense the amount of ambient light, and a lighting control unit for controlling the amount of voltage or current input to the vehicle indicator according to the amount of ambient light. will be. Since the light sensor or the photo sensor generates a current proportional to the intensity of the light, the lighting controller reduces the current or voltage applied to the vehicle indicator to reduce the brightness of the vehicle indicator when the current generated from the photo sensor is large. When the current generated from the light sensor is low and the current is low, the voltage or current applied to the vehicle indicator may be increased to increase the brightness of the vehicle indicator.

In this way, the vehicle lights are brightly lit in bright surroundings to enhance identification, and mainly the headlights are turned on, so in night or dark rooms where vehicle identification is easy, the brightness of the vehicle lights according to the present invention is lowered to reduce power consumption. It is desirable to.

The vehicle indicator used in the present invention basically uses a light emitting diode element (LED), and there is no limitation as long as it can secure the brightness or luminance to identify the vehicle even in the daytime.

That is, as shown in FIG. 4A, a plurality of LEDs having relatively low brightness may be arranged on a plane, and as shown in FIG. 4B, some LEDs having a relatively large advertisement may be arranged linearly.

In addition, although not shown, by implementing a single vehicle indicator with a plurality of different types of LEDs, one vehicle indicator may be used to express various colors to enhance discrimination.

In addition, by attaching a diffusion sheet on the base of the LED will be able to improve the identification ability by doubling the diffusion capacity.

When a start start signal, that is, a high voltage signal is input from the start detection unit, is maintained on and maintained, the start end signal from the start detection unit. And a switch that is turned off when the low voltage signal is received. This switch consists of one part in a closed circuit in which the + terminal (B +) of the battery of the vehicle and the fuse and the vehicle indicator are connected in series to the ground or-terminal (B-) of the battery.

Referring to the operation state of the lighting relay, when the start start signal is received from the start detection unit, the switch is turned on and current flows from the + terminal of the battery to the vehicle indicator to turn on the indicator. As mentioned above, the switch remains on until the start end signal is received, and the start of the vehicle turns off when the start signal is received.

The relay unit is not necessarily limited to this form, and a relay unit using an excitation coil commonly used for other headlight ignition may be used.

The lighting controller may further include a lighting controller, and as described above, the lighting controller performs a control operation such as adjusting brightness of a vehicle indicator according to ambient brightness, adjusting a lighting state of each vehicle indicator, and the like.
