ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a multifunctional safety warning device, and more particularly to a multifunctional safety warning device for a vehicle such as an automobile, motorcycle, bicycle and the like.
2. Description of the Related Art
The closest prior art of which the applicant is aware is disclosed in his U.S. patent application Ser. No. 09/213,276, entitled by “AUXILIARY SAFETY WARNING LAMP SYSTEM FOR A VEHICLE”, which is now allowed.
A conventional warning light is mounted on an inside of the rear windshield of a car for indicating the situation of the car when it is braking so as to warn and remind the following car.
However, the warning light is directly connected to the braking light so that the warning light functions the same as the braking light, and cannot increase the warning effect.
In addition, the warning light is a red light continuously lighting so as to provide a warning effect. When the car breaks down or when it is in a bad viewing condition such as in a cloudy, foggy, typhoon, or rainy day, two yellow directional lights of the car will blink to warn the following car. During the successive travel, it needs to turn on the yellow directional light when the car is turned left or right so that a blind point is created, thereby causing a dangerous condition.
Further, when the right directional light and the left directional light are allowed to be close to each other, if the distance of viewing is increased, the two close points are easily mistaken as the same point, especially when the viewing condition is bad so that it is not easy to distinguish if the point at a far spaced distance is the right directional light or the left directional light, thereby greatly causing confusion to the following car.
Moreover, when the right directional light and the left directional light respectively have a right directed arrow and a left directed arrow, the light at a far distant position will be taken as a spot so that it is not easy to distinguish if the spot is the right directional light or the left directional light, thereby greatly causing confusion to the following car.
Further, the warning light often provides a warning function, and cannot be used to provide a direction indicating function.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional warning light.
In accordance with one aspect of the present invention, there is provided a multifunctional safety warning device for a vehicle comprising: a mediate light bar zone having a first side and a second side; a left indicating light mounted on the first side of the mediate light bar zone and being adapted to light independently; and a right indicating light mounted on the second side of the mediate light bar zone and being adapted to light independently.
By such an arrangement, the mediate light bar zone, the left indicating light, and the right indicating light are connected to and controlled by a control unit, whereby, the control unit is used to alternatively operate the mediate light bar zone, the left indicating light, and the right indicating light of the safety warning device, and to operate a set of breakdown light of the vehicle so that at least one set of light is used indicate a steering direction of the vehicle.
When the breakdown light of the vehicle blinks, the control unit is used to operate the left indicating light and the right indicating light of the safety warning device so that the left indicating light and the right indicating light do not blink so as to indicate a turn left/right steering direction of the vehicle.
When the left indicating light and the right indicating light of the safety warning device blink, the control unit is used to operate the breakdown light of the vehicle so that breakdown light of the vehicle does not blink so as to indicate a turn left/right steering direction of the vehicle.
When the left indicating light and the right indicating light of the safety warning device blink, the control unit is used to operate the mediate light bar zone so that the mediate light bar zone lights continuously, thereby facilitating a far following vehicle apparently distinguishing the left indicating light and the right indicating light and knows a front vehicle is disposed at an emergency state.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
