Description:
BACKGROUND OF THE INVENTION  
       [0001]     (a) Technical Field of the Invention  
         [0002]     The present invention is related to a light emitting diode indicator set with radio signal transmitter, and more particularly, to one that is adapted to a motor vehicle to transmit radio signals simultaneously with light emission.  
         [0003]     (b) Description of the Prior Art  
         [0004]     Additional to head lamps, a direction indicator set  1  including direction indicator lamp  10 , reversing light lamp  11 , rear indicator lamp  12  and braking indicator lamp  13  as illustrated in  FIGS. 1 and 2  is generally provided to various locations of a motor vehicle.  
         [0005]     As illustrated in  FIG. 3 , the direction indicator lamp  10  is essentially comprised of an adapter  101 , a housing  102  and a tungsten bulb. Wherein, a bulb sleeve  104  is provided in the adapter  101 , and a power cable  105  adapted with a power switch is connected to the battery of the vehicle for power supply. The design of the structural form of the bulb sleeve  104  in the adapter  101  compromises that of a holder  1030  of the tungsten bulb  103 . Even though the design may vary among manufacturers, fast removal and mounting as well as secured fixation generally govern the design. When the tungsten bulb  103  is fixed with its holder  1030  in the bulb sleeve  104  of the adapter  101 ; the adapter is incorporated to the housing  102  to complete the assembly of the direction indicator lamp  10  and the assembly is then mounted to the rear of the vehicle. The driver by operating the switch turns on the tungsten bulb  103  to achieve indication and warning purposes.  
         [0006]     Whereas the indicator lamp  10  has been used to a vehicle for quite a long time, many motor manufacturers and consumers have gradually found out that the indicator lamp  10  does not necessarily fall within the range of the optimal vision for being limited to the style of the body of the vehicle. Accordingly, the indicator lamp  10  cannot be easily seen by people in other vehicles or pedestrians. Usually, the vehicle is moving, and the visual range changes constantly to result in many blind angles to discount the indication and warning functions of the indicator lamp  10 .  
         [0007]     To correct this, many drivers choose to add certain warning devices to other locations on the body of the vehicle. A reflection sticker A as illustrated in  FIG. 4  is adhered to a helmet in case of a motorcycle rider as illustrated in  FIG. 5  or on the clothing as illustrated in  FIG. 6  to further improve the attention upon reflecting the light emitted from other vehicle. However, the result of the reflection sticker A is very limited since it is not a light-emitting source. Its performance is determined by the luminance of the external light source and its respective range with that light source. Therefore, the reflection sticker is considered as a passive and uncertain type of application.  
       SUMMARY OF THE INVENTION  
       [0008]     The primary purpose of the present invention is to provide an LED indicator set adapted with a radio signal transmitter so that when the LED indicator set is conducted, the light is emitted and the radio signal is transmitted.  
         [0009]     Another purpose of the present invention is to provide an LED indicator set adapted with a radio signal transmitter to transmit signals to an external warning indicator to light up the LED bulb in the external warning indicator for achieving warning results.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0023]     The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
         [0024]     The present invention is related to an LED indicator set adapted with a radio signal transmitter. Referring to  FIG. 7 , the LED indicator set  2  includes an adapter  20 , a radio signal transmitter  21 , a protection cap  22  and an LED indicator group  23  comprised of multiple light emitting diodes. As illustrated in  FIG. 8 , the adapter  20  is provided with a contact  201  connected to a radio signal transmitter  21  through a conductor  202 . The radio signal transmitter is provided with an electronic circuit set  211  for the transmission of signals, and an antenna  212  for the transmission. The LED indicator set  23  is fixed to a motherboard  231 , and another electronic circuit set  232  to be applied by the LED indicator group  23  is provided to the motherboard  231 . A conductor  233  connects both electronic circuit sets  211 ,  232  respectively from the radio signal transmitter  21  and the motherboard  231  even if the LED indicator group  23  and the radio transmitter  21  are connected in series. Both of the LED indicator group  23  and the radio signal transmitter  21  are covered by the protection cap  22 . Once the power is supplied, the LED indicator group  23  is emitting light and the radio signal transmitter  21  transmits the preset signals.  
         [0025]     Now referring to  FIG. 9 , the present invention is applied to a general vehicle (in the form of a braking lamp, a direction indicator lamp and a reversing indicator lamp). Wherein, the user may forthwith remove the tungsten bulb and replace it with the LED indicator set  2  of the present invention. An external warning indicator set B comprised of multiple LED indicators B 1 , a radio signal receiver and a switch is further provided in relation to the radio signal transmitter in the LED indicator set  2 . The outer side is attached with an adhesive element such as a magnet or a double-faced adhesive tape.  
         [0026]     In practice as illustrated in  FIG. 10 , the adapter  20  of the LED indicator set  2  of the present invention is fixed to the bulb protection cap of the vehicle, and the switch at the external warning indicator set B is turned on to enter into standby status for receiving signals and light emission. The LED indicator set  2  procures the power and control through the power cable and the switch in the protection cap  22 . When the direction indicator, the braking indicator or the reversing indicator lamp is activated through the system designed for the vehicle, the LED indicator group  23  in the LED indicator set  2  is lighted to execute its indication function. Meanwhile the radio signal transmitter in the LED indicator set  2  transmits its signals at the same time. Upon picking up the radio signals by the receiver in the external warning indicator set B, those multiple LED indicators B 1  of the external warning indicator set B are activated for light emission to provide further warning function. Furthermore, when the present invention is applied to a motorcycle, the external warning indicator set B is fixed to the helmet or the back of the rider to highlight visual exposure. If the present invention is applied in a heavy-duty vehicle such as a bus, truck, truck tractor, or a tandem tractor trailer, the external warning indicator set B may be fixed to both sides or the upper rear of the body as illustrated in  FIG. 11  to serve further warning purpose. When applied in a semi-trailer, the external warning set B may be stick to the body at where as desired by means of a magnet. Upon completing the unloading, the external warning set B is removed for the next application to achieve convenient and economic benefits.  
         [0027]     The light color of the LED indicator group  23  in the LED indicator set  2  of the present invention may be selected as desired and may be connected in parallel to make sure that in the event that the failure of certain LED indicators will not affect the light emission by the remaining LED indicators.  
         [0028]     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.  
         [0029]     While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
