Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a license plate light having an attached video camera and this license plate light is suitable for various vehicles or the likes.  
       BACKGROUND OF THE INVENTION  
       [0002]     The motor vehicle is a kind of very convenient transportation tool. By using the rearview mirrors, which are mounted on both sides and the center of the vehicle, the driver can observe the surrounding images from the vehicle&#39;s seat. However, these rearview mirrors cannot reflect the images right behind the vehicle. In response to this, the vehicle is provided with the backing radar and the video camera. Besides, many vehicles are also provided with light sources above the license plates so as to show the license plate number clearly.  
         [0003]     However, the conventional license plate light and video camera are mounted independently. Two wiring paths must be provided in order to assemble both of them. As a result, it takes a long time for attaching the light sources and the video camera to the vehicle. It means that this vehicle is not available for a long time and the assembly cost is thus very high. Moreover, the conventional backing radar is generally mounted on the center of the bumper or on the top of the vehicle. As a result, the driver can observe the captured images from the video camera via the monitor while backing the vehicle so as to avoid collision or danger by observing the rear images.  
         [0004]     However, the mounting position of the conventional video camera is so excessively high or low that the capture angle of the video camera is confined. When the video camera is mounted on a lower bumper, the capture images cannot be recognized clearly in a darker surrounding. Moreover, when the video camera is mounted on a lower bumper, it is easily damaged by careless backing or impacted by other vehicle in the rear.  
         [0005]     In view of the foregoing defects, the present inventor makes diligent studies in providing consumers with a license plate light having an attached video camera according to the motive of the present invention.  
       SUMMARY OF THE INVENTION  
       [0006]     It is a main object of the present invention to integrate a video camera with a license plate light such that they can share a wiring path.  
         [0007]     It is another object of the present invention to combine a video camera with a license plate light for providing the license plate number and the video camera with proper illumination, thereby obtaining the clear images.  
         [0008]     In order to achieve the above-mentioned objects, the present invention discloses a license plate light comprising: a box; at least one light-emitting device mounted inside said box; a video camera mounted inside said box; and a transparent cover coupled with said box, whereby said at least one light-emitting device and said video camera integrate with each other and share a wiring path to facilitate vehicle&#39;s wiring.  
         [0009]     The aforementioned objects and advantages of the present invention will be readily clarified in the description of the preferred embodiments and the enclosed drawings of the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0014]     Referring to  FIG. 1  and  FIG. 2 , a license plate light having an attached video camera of the present invention comprises a box  1 , at least one light-emitting device  2 , a video camera  3 , a transparent cover  4 , and a camera-protecting cover  5 , wherein an amount of plug is mounted on the inside of the box  1  in response to that of the light-emitting device  2 . In this preferred embodiment, two plugs  11 ,  12  are mounted on both inner sides of the box  1 , respectively. Besides, a protrudent flange  13  is formed outwardly, horizontally on an opening of the box  1 .  
         [0015]     The above-mentioned light-emitting device  2  is, for example, a light bulb, a light-emitting diode, etc. In this preferred embodiment, two light-emitting diodes are exemplified. Referring to  FIG. 3  simultaneously, each light-emitting device  2  comprises two light-emitting diodes  213 , which are attached to a circuit board  212 , wherein a socket  211  is attached to the backside of the circuit board  212 . In addition, a light-condensing frame  21  is utilized to cover the light-emitting diodes  213 , the circuit board  212 , and the socket  211 .  
         [0016]     The video camera  3  is connected to the box  1 .  
         [0017]     The transparent cover  4  is located to conform to the protrudent flange  13 , which is located on the opening of the box  1 . In addition, a hole  41  is formed on the center of the transparent cover  4 .  
         [0018]     The camera-protecting cover  5  is coupled to the hole  41  of the transparent cover  4 , wherein the bottom the camera-protecting cover  5  is formed to be two inward-slanted lateral surfaces. In addition, a protrudent part  51  is formed on one of the lateral surfaces. Alternatively, the transparent cover  4  may be integrally coupled with the camera-protecting cover  5 .  
         [0019]     In the assembly process, the plugs  11 ,  12  of the box  1  are firstly inserted into the sockets  211  of these two light-emitting devices  2  such that the video camera  3 , which is connected to the box  1 , can be located between these two light-emitting devices  2 . Then, the camera-protecting cover  5  is embedded in the hole  41  of the transparent cover  4 . Thereafter, the video camera  3  is located on the protrudent part  51  of the camera-protecting cover  5 . Finally, the transparent cover  4  is coupled with the protrudent flange  13 , which is located on the opening of the box  1 .  
         [0020]     When in use, as shown in  FIG. 1  through  FIG. 4 , the box  1  is attached above a license plate  61 , which is located on the backside of a vehicle  6 , wherein the protrudent part  51  of the camera-protecting cover  5  is located to face outward so as to capture images behind the vehicle  6 . In addition, the camera-protecting cover  5  is designed to protect the video camera  3  against dust and rain and to prevent damage. Besides, the light emitting devices  2 , which are mounted on both sides of the video camera  3 , respectively, can downward emit light beams via the transparent cover  4  to show the license plate number clearly.  
         [0021]     In accordance with the foregoing description, it is apparent that the license plate light of the present invention provides the following advantages, wherein:  
         [0022]     1. the light-emitting devices and the video camera can be integrated effectively with each other such that these two components can be assembled simultaneously by one assembly step;  
         [0023]     2. the required time for assembling the light-emitting devices and the video camera to the vehicle can be shortened effectively and the assembly cost can be reduced as well; and  
         [0024]     3. the light beams emitted from the light-emitting devices not only clearly illuminates the license plate number but also provides the video camera with proper illumination for capturing images clearly.  
         [0025]     In summary, the license plate light having the attached video camera of the present invention can integrate the light-emitting devices with the video camera effectively. Accordingly, the present invention satisfies patentability and is therefore submitted for a patent.  
         [0026]     While the preferred embodiment of the invention has been set forth for the purpose of disclosure, modifications of the disclosed embodiment of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments, which do not depart from the spirit and scope of the invention.
