  • DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
  • [0008]
    Please refer to Fig. 1, which illustrates a structure diagram of a light emitting diode according to a first embodiment of the present invention.
  • [0009]
    As illustrated in Fig. 1 in the first embodiment of the invention, the light emitting module 1 includes a main base board 10, a wireless communication module 20, a plurality of light emitting diodes 30, a power output control system 40 and a control unit 50. The invention, however, is not limited to such configuration. For example, the wireless communication module 20 and the control unit 50 may be combined to be a single unit.
  • [0010]
    In the first embodiment of the invention, the main base board 10 is made of aluminum material and the main base board 10 has a circular plate shape. The invention, however, is not limited to such configuration. For example, the shape of the main base board 10 can be designed as an irregular shape according design requirements.
  • [0011]
    In the first embodiment of the invention, the wireless communication module 20 is disposed on the main base board 10. The wireless communication module 20 includes an antenna 21 that extends to one side of the main base board 10 for preventing signals from being blocked due to a shielding effect to the antenna 21. The wireless communication module 20 is used (is capable of being used) for receiving a control signal of a user. In the embodiment, the wireless communication module 20 is a Bluetooth device and the antenna 21 is a Bluetooth antenna. The invention, however, is not limited to Bluetooth devices, and may, for example, cover infrared transmission devices, wireless network devices or voice control devices. For example, the wireless communication module 20 can be a voice control device, and the control signal can be a voice control signal.
  • [0012]
    In the first embodiment of the invention, the light emitting diodes 30 are disposed on the main base board 10. The light emitting diodes include a red light emitting diode 31, a green light emitting diode 32, a blue light emitting diode 33 and a white light emitting diode 34. In the embodiment, the light emitting diodes 30 are integrated in the same light ball. By adjusting the brightness of the light emitting diodes of different colors 31, 32, 33 and 34, the light emitting diode as a whole emits light of various colors; i.e., the light ball emits light of multiple colors, including colors other than red, green, blue and white.
  • [0013]
    In the first embodiment of the invention, the power output control system 40 is disposed on the main base board 10. The power output control system 40 includes a plurality of power output controllers 40a, 40b, 40c and 40d, and each power output controller 40a, 40b, 40c and 40d is respectively electrically connected to the light emitting diodes 31, 32, 33 and 34 having different colors. The power output control system 40 is used (is capable of being used) for receiving current input from the power source 90 and adjusts the amounts of current being output to each of the light emitting diodes 31, 32, 33 and 34. By adjustment of the amounts of current flowing through each of the light emitting diodes 31, 32, 33 and 34, the color or brightness of the plurality of light emitting diodes as a whole can be changed. For example, when the power output control system 40 controls current of a certain ratio flowing through the red light emitting diode 31 and the green light emitting diode 32 while no current is flowing through the blue light emitting diode 33 and the white light emitting diode 34, the plurality of light emitting diodes as a whole give out yellow light.
  • [0014]
    In the first embodiment of the invention, the control unit 50 is disposed on the main base board 10 and is electrically connected to the wireless communication module 20 and the power output control system 40. The control unit 50 includes a memory module 51 and a timer 52. The memory module 51 is used (is capable of being used) for storing a control parameter so that after the control unit 50 receives the control signal, the power output control system 40 adjusts the input current flowing to each light emitting diode 30 according to the control parameter. As such, the color, brightness or timing of light emission of the plurality of light emitting diodes may be controlled. In addition, the control unit 50 may individually be used for controlling the color, brightness, or positive or negative light emission according to the control signal input by users. The timer is used (is capable of being used) for counting time.
  • [0015]
    For example, users may set a time parameter of a timing switch of the light emitting diode module 1 via a Bluetooth device of a mobile phone. For example, the light emitting diode module 1 is set to emit light from 11 pm each evening to 8 am the next morning. After the control parameter is input from a mobile phone to the light emitting diode module 1, it is stored in the memory module 51 of the control unit 50. After users program the timer to emit light from 11 pm every night to 8 am the next morning, i.e., inputting the control signal, the control unit 50 controls the light emitting diode 1 to emit light during the set time. On the other hand, when users want to cancel the timing switch function of emitting light from 11 pm each night to 8 am the next morning, users may use their Bluetooth devices to turn off the timing switch function. After it is turned off, the control unit 50 no longer controls the light emitting diode module 1 to emit or not to emit light according to the control parameter that was set previously. In addition, users may use Bluetooth devices to delete or to reset the control parameter or to add a new control parameter to the memory module 51. For example, in addition to emitting light from 11 pm each night to 8 am the next morning, the control unit 50 can be set such that light is automatically emitted from 5 pm each evening to 8 pm at night.
  • [0016]
    For another example, users may use Bluetooth devices in their mobile phones to input color parameters for changing the color of light emitted by the light emitting diode module 1 during different times. For example, the light emitting diode module 1 may be set to emit white light from 6 pm each evening to 11 pm at night, and to emit red light from 11 pm at night to 6am the next morning. Similarly, these control parameters are input to the light emitting diode module 1 and then are stored in the memory module 51 for users to request the control unit 50 to execute.
  • [0017]
    Next, please refer to Fig. 2, which illustrates a structure diagram of a light emitting diode module according to a second embodiment.
  • [0018]
    As shown in Fig. 2, in a second embodiment of the present invention, the main base board 10 has a breaking hole 11, and the antenna 21 is located at the position of the breaking hole to prevent signals from being blocked due to shielding of the main base board 10.
  • [0019]
    Please refer to Fig. 3, which illustrates a structure diagram of the light emitting diode module in a third embodiment of the present invention.
  • [0020]
    As illustrated in Fig. 3, in a third embodiment of the present invention, the main base board 10 has a communication area 12. The communication area 12 is made of plastic material, and the antenna is located in the communication area 12 to prevent signals from being blocked due to a shielding effect.
  • [0021]
    Please refer to Fig. 4, which illustrates a light emitting diode module in a fourth embodiment of the present invention.
  • [0022]
    As illustrated in Fig. 4, in a fourth embodiment of the present invention, the wireless communication module 20 and the antenna 21 of the light emitting diode module 1 are located outside the main base board. In such a way, the shielding effect is also prevented.
  • [0023]
    Please refer to Fig. 5, which illustrates a structure diagram of a light emitting diode module in a fifth embodiment of the present invention.
  • [0024]
    As illustrated in Fig. 5, in a fifth embodiment of the present invention, the light emitting diode module 1 further includes a sub base board 60. The sub base board 60 is made of non-metal material. The wireless communication module 20 and the antenna 21 are disposed on the sub base board 60. Because the sub base board 60 is made of non-metal material, it causes no shielding effect for the antenna 21, and thus such approach also prevents blocking of the signals for the antenna 21 due to a shielding effect.
  • [0025]
    Next, please refer to Fig. 6, which illustrates a structure diagram of a light emitting diode module in a sixth embodiment of the present invention.
  • [0026]
    As illustrated in Fig. 6, in a sixth embodiment of the present invention, the shape of the main base board 10 is not a circular plate shape but has a gap 13, and the sub base board is disposed at the position of the gap 12. With such a design, the material cost of manufacturing the main base board 10 and the sub base board 60 is reduced, and the space occupied by the two components is also reduced so as to reduce the size of the light emitting diode module 1. The invention, however, is not limited to such configuration. The communication module 20 may also cross between the main base board 10 and the sub base board 60, and the antenna may remain in the range of the sub base board 60. As such, the manufacturing cost of connecting lines between the main base board 10 and the sub base board 60 can be further reduced.
  • [0027]
    Next, please refer to Fig. 7, which illustrates a structure diagram of a light emitting diode module in a seventh embodiment of the present invention.
  • [0028]
    As illustrated in Fig. 7, in the seventh embodiment of the present invention, the difference between the seventh embodiment and the fifth embodiment is primarily that the wireless communication module 20 and the antenna 21 are separately disposed. That is, the wireless communication module 20 is disposed on the main base board 10, and the antenna 21 is disposed on the sub base board 60. As such, the manufacturing cost and the size of the sub base board 60 can be reduced. The present invention, however, is not limited to such configuration. The antenna 21 can be electrically connected to the wireless communication module 20, and there is no need for the sub base board 60 at all.
  • [0029]
    Finally, please refer to Fig. 8, which illustrates a structure diagram of a light emitting diode module in an eighth embodiment of the present invention.
  • [0030]
    As illustrated in Fig. 8, in an eighth embodiment of the present invention, the difference between the eighth embodiment and the fifth embodiment is primarily that the control unit 50 is disposed on the sub base board 60 so as to reduce the size and manufacturing cost of the main base board.
