(6) In the first embodiment of the present invention, an optical communication lamp device comprises a receiving-end driving power circuit 10, a receiving-end power circuit receiver 11, an emitting-end emitter 12, a power unit 13, a lamp tube heat-dissipation member 14, an emitting-end driving controller 15, at least one lamp socket 16, a test switch 17, a test indicating light 18, a lightshade 19, and a light emitting element 20.

(7) The lamp tube heat-dissipation member 14 is an aluminum manufacture. The lamp tube heat-dissipation member 14 has an assembly surface. The receiving-end driving power circuit 10, the receiving-end power circuit receiver 11, the emitting-end emitter 12, the power unit 13 and the emitting-end driving controller 15 are disposed on the assembly surface of the lamp tube heat-dissipation member 14. The power unit 13 may be a battery or a chargeable battery. The emitting-end emitter 12 may be an optical emitting member. The receiving-end power circuit receiver 11 may be an optical receiving member.

(8) The receiving-end driving power circuit 10 is electrically connected to the receiving-end power circuit receiver 11. The emitting-end emitter 12 is electrically connected to the emitting-end driving controller 15.

(9) The lampshade 19 covers the assembly surface of the lamp tube heat-dissipation member 14, so that the receiving-end driving power circuit 10, the receiving-end power circuit receiver 11, the emitting-end emitter 12, the power unit 13 and the emitting-end driving controller 15 are between the lampshade 19 and the lamp tube heat-dissipation member 14.

(10) The light emitting member 20 may be a plate member having a plurality of light emitting diodes. The light emitting member 20 is disposed between the lampshade 19 and the lamp tube heat-dissipation member 14. The light emitting element 20 is electrically connected to the receiving-end driving power circuit 10, the power unit 13, and the emitting-end driving controller 15.

(11) In this embodiment, the number of the lamp sockets 16 is two. The two lamp sockets 16 are respectively disposed on two ends of an assembly of the lampshade 19 and the lamp tube heat-dissipation member 14. Each of the lamp sockets 16 has a copper pin 160, and the copper pin 160 is electrically connected to the light emitting element 20.

(12) The test switch 17 and the test indicating light 18 are disposed on one end of the lampshade 19 and electrically connected to the light emitting element 20.

(13) Please refer to FIGS. 2 and 3. When the copper pin 160 of the lamp socket 16 is connected to a power supply source, for example, a mains supply or a test power supply, the power supply provides electricity to the light emitting element 20 through the copper pin 160, so that the light emitting diodes of the light emitting element 20 illuminate lights. The lights are then emitted outwardly through the lampshade 19 for illuminating the space outward the lamp device. Moreover, the electricity can charge the power unit 13 at the same time.

(14) When the test switch 17 is turned on, the power supply does not provide electricity to the light emitting element 20; instead, the power unit 13 provides electricity to the light emitting element 20, so that the light emitting diodes of the light emitting element 20 illuminate lights. Moreover, the test indicating light 18 is turned on so as to indicate that the power unit 13 of the lamp device is in use or the lamp device is in a test state.

(15) When the test switch 17 is turned off, the power unit 13 does not provide electricity to the light emitting element 20, and again the power supply provides electricity to the light emitting element 20. Moreover, the test indicating light 18 is turned off so as to indicate that the lamp device is in a charging state or the lamp device is powered by the power supply.

(16) A controller 150 (for example, may be or may have an encoder) emits an electrical signal (which is a duty ratio signal with a specific frequency), e.g., an electrical signal with a frequency from 1 Hz to 100 KHz. The emitting-end driving controller 15 receives the electrical signal emitted from the controller 150. The electrical signal is converted by the emitting-end emitter 12 to be an optical signal with a certain wavelength. The optical signal is radiated to the space having the lamp device through the emitting-end emitter 12.

(17) The receiving-end power circuit receiver 11 receives the optical signal from the emitting-end emitter 12, and converts the optical signal into an electrical signal (which is a duty ratio signal with a specific frequency), and then the electrical signal is amplified and transmitted to a decoder of the receiving-end driving power circuit 10 for decoding. The decoded signal is then outputted by the decoder to execute a corresponding signal, for example, to allow the lamp device to be in a mode in which the electricity is powered by the power supply or in a mode in which the electricity is powered by the power unit 13.

(18) According to one or some embodiments, the optical communication lamp device has following advantages. First, the electrical signal (with high and low level) is transmitted to the emitting-end emitter 12, and then is converted by the emitting-end emitter 12 to be an optical signal with a specific wavelength, and the optical signal is radiated to the space where the lamp device is located. Next, the receiving-end power circuit receiver 11 receives the signal from the emitting-end emitter 12 and converts the optical signal into a second electrical signal (a duty ratio signal with a specific frequency). Then the second electrical signal is amplified to allow the receiving-end driving power circuit 10 to perform the high and low level signal control. Second, the two electrical-isolated systems within the lamp tube and the enclosed lamp device are capable of performing communication through the optical emitting and receiving components. Third, issues of the electromagnetic waves produced by the control of the wired-connected components can be reduced. Fourth, compared with radiofrequency communication, optical communication does not generate additional radio frequency electromagnetic wave problems. Fifth, the production efficiency can be improved and the cost problem caused by using the wire can be reduced.

Accordingly, the invention is not to be limited except as by the appended claims.
