说明书全文 | The present invention is related to a light indication device used for a helmet and a transportation and more particular to a wireless light indication and control device. Recently, bicycle riding has become a fever. However, in Taiwan, because the bike lanes are still not popular, the bicycles always have to barrow the motorcycle lanes and compete therewith, which easily causes danger, especially during the rush hour. And, since most bicycles are not equipped with the warning device, the rider's safety is highly threatened. Nowadays, wireless technology is getting matured and has applied to various kinds of daily used products, such as mobile phones and computers. R.O.C. patent No. 588784 has disclosed the “Structure of brake warning light”, wherein, as shown in In R.O.C. patent No. M351002, entitled “Helmet with turning signal lights”, as shown in Therefore, in addition to the warning device mounted on the bicycle, the helmet 3 and the light module 4 also should be improved for solving the defect of manual operation. Further, it is also important to avoid the signal interference among multiple receivers on the helmets and multiple transmitters on the bicycles, otherwise not only the warning function will be influenced, the rider's safety might also be impaired. The object of the present invention is to provide a wireless light indication and control device, in which the light indication is controlled by the helmet and which provides functions of frequency hopping and matching. For achieving the object described above, the present invention provides a wireless light indication and control device connected with a helmet. The wireless light indication and control device includes a direction detector, a wireless transmitter, and at least one light element, wherein the direction detector is mounted on the helmet for sensing a movement of the helmet so as to generate a turning signal, the wireless transmitter is mounted on the helmet and electrically connected with the direction detector for receiving the turning signal and for cooperating with a frequency hopping unit and a matching unit to generate a wireless signal, and the light element includes a wireless receiver for receiving the wireless signal. Accordingly, the wireless light indication and control device of the present invention is advantageous that: 1. The direction detector mounted on the helmet can generate the turning signal based on sensing the movement of user's head and then wirelessly transmits the turning signal to the light element, so that no matter during the normal riding condition or in an emergency, the warning indication can be generated and shown concurrently, thereby improving the safety. 2. The first light module on the helmet includes at least two indication lights which can respectively indicate the right turn and the left turn, so as to provide the bicycle the turning signals like other transportations. 3. The frequency hopping unit and the matching unit used for wireless transmission can avoid the wireless signal interference or failure when multiple wireless light indication and control devices are gathering around, so as to further improve the riding safety. The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein: Please refer to The light element 13 can further include a power supply device 16, which can be a general battery or a solar battery. In this embodiment, the power supply device 16 is a general battery. Besides, the light element 13 also includes at least two indication lights 17 for showing the turning signals. Please refer to Please refer to Furthermore, in the present invention, the frequency hopping unit 14 adopts AFH (Adaptive Frequency Hopping) technology which is generally used for bi-directional wireless communication and data encryption in the wireless communication, wherein the wireless communication frequency division allows channel switching and hopping as transmission and receiving so as to ensure the communication quality. The matching unit 15 encrypts the data before transmission, so as to ensure the data security and also the correctness of data destination. Accordingly, even multiple users are gathering around a neighborhood, the frequency hopping unit 14 and the matching unit 15 also can automatically detect the frequency of other wireless light indication and control devices and avoid the interference thereamong. Therefore, the transmission error or failure of the light element 13 which might cause traffic danger can be prevented. In the aforesaid, the present invention utilizes the direction detector 11 to sense the movement of the helmet 10 for indicating the turn of the user's riding so as to make up the deficiency that the bicycle does not have the turning signals for warning like the motorcycle. The wireless transmission technology provides the flexibility in mounting the light element 13 on the helmet 10 or the transportation 20. Moreover, the light element 13 includes two indication lights 17 which can show the right turn and the left turn indications. Besides, the frequency hopping unit 14 and the matching unit 15 can prevent the wireless signal interference as multiple wireless light indication and control devices are gathering around, so as to further ensure traffic safety. It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. |
