Description of the Related Art

Currently, there are two types of the related art light emitting diode lamps: the serial-type light emitting diode lamp and the parallel-type light emitting diode lamp. Both the serial-type light emitting diode lamp and the parallel-type light emitting diode lamp need to use a plurality of power transmission lines and signal transmission lines, which waste wires. Afterwards, the related art technology which transmits the lighting signal through the power transmission lines is provided to save the signal transmission lines, wherein the lighting signal comprises the lighting data and the address data.

The local address data has to be burned into the light emitting diode driving apparatus when the light emitting diode driving apparatus is manufactured. The light emitting diode driving apparatus checks whether the address data of the lighting signal is the same with the local address data or not when the light emitting diode driving apparatus receives the lighting signal mentioned above. The light emitting diode driving apparatus drives the light emitting diode to light according to the lighting data of the lighting signal if the address data of the lighting signal is the same with the local address data of the light emitting diode driving apparatus.

However, the disadvantage of the method mentioned above is that once the light emitting diode driving apparatus has been manufactured, the local address data cannot be changed. Therefore, it is very inconvenient for the warehouse management. Moreover, it is also very inconvenient for assembling a lot of the light emitting diode driving apparatuses because the operator has to check the local address data of every light emitting diode driving apparatus carefully to avoid assembling the incorrect light emitting diode driving apparatus.

The burning signal detector128wirelessly receives a wireless starting signal202and a wireless address signal204from outside (namely, from the burner2). The burning signal detector128converts the wireless starting signal202into a wired starting signal206and converts the wireless address signal204into a local address signal208. The burning signal detector128orderly transmits the wired starting signal206and the local address signal208to the address burning controller126. When the address burning controller126receives the wired starting signal206, the address burning controller126is configured to burn the local address signal208into the address memory124, so that the address memory124stores a local address data312.

The signal conversion unit108receives a first signal302through the positive contact102. The signal conversion unit108converts the first signal302into a second signal304and sends the second signal304to the address and data identifier110.

The optical element12802wirelessly orderly receives the wireless starting signal202and the wireless address signal204from outside. Namely, the burner2wirelessly orderly transmits the wireless starting signal202and the wireless address signal204to the optical element12802. The optical element12802senses and converts the wireless starting signal202into a first sensing signal210.

FIG. 4shows a block diagram of the light emitting diode system of the present invention. The descriptions of the elements shown inFIG. 4which are the same as the elements shown inFIG. 1andFIG. 2are not repeated here for brevity. A light emitting diode system3receiving the contactless burning signal comprises the light emitting diode lamp1mentioned above and a burner2. The burner2is wirelessly electrically connected to the light emitting diode lamp1. The burner2comprises a light emitting unit21and a light receiving unit22. The light receiving unit22is electrically connected to the light emitting unit21.

The light emitting unit21wirelessly transmits the wireless starting signal202and the wireless address signal204to the light emitting diode lamp1. The light emitting diode lamp1converts the local address data312into a wireless local address data314. The light emitting diode20flickeringly lights to transmit the wireless local address data314to the light receiving unit22, so that the burner2converts the wireless local address data314into the local address data312and determines whether the local address data312is correct or not. The light receiving unit22is a PN junction (or a PN interface), a photo transistor or a photo diode.

Moreover, besides the above-mentioned method for determining whether the local address data312is correct or not by the burner2, the present invention can also utilize the address data308and the lighting data310mentioned above to determine whether the local address data312is correct or not. Namely, as mentioned above, if the address data308is the same with the local address data312, the light emitting diode driving circuit118drives the light emitting diode20to light according to the lighting data310. Therefore, if the light emitting diode20is able to light, the local address data312is determined as correct. If the light emitting diode20is not able to light, the local address data312is determined as incorrect.

FIG. 3shows a flow chart of an embodiment of the burning address method of the present invention. A burning address method for the light emitting diode lamp receiving the contactless burning signal of the present invention comprises following steps.

Step S02: A burner wirelessly orderly transmits a wireless starting signal and a wireless address signal to a burning signal detector.

Step S04: The burning signal detector converts the wireless starting signal into a wired starting signal and converts the wireless address signal into a local address signal.

Step S06: The burning signal detector transmits the wired starting signal and the local address signal to an address burning controller.

Step S08: The address burning controller determines whether the address burning controller receives the wired starting signal or not. If not, the burning address method goes to a step S10. If yes, the burning address method goes to a step S12.

Step S10: The address burning controller omits the local address signal. Then the burning address method returns to the step S02.

Step S12: The address burning controller burns the local address signal into an address memory, so that the address memory stores a local address data.

Step S14: A light emitting diode (for example, the light emitting diode20shown inFIG. 1) is utilized to flickeringly light to transmit the local address data to the burner to determine whether the local address data is correct or not. If the burner determines that the local address data is incorrect, the burner wirelessly orderly re-transmits the wireless starting signal and the wireless address signal to the burning signal detector. If the burner determines that the local address data is correct, the burning address method is finished or the burning address method for another light emitting diode lamp is performed. Moreover, it is noted that the step S14is to verify whether the local address data is correct or not, but the step S14is not an essential step of the burning address method of the present invention.

FIG. 5shows a flow chart of another embodiment of the burning address method of the present invention. A burning address method for the light emitting diode lamp receiving the contactless burning signal of the present invention comprises following steps.

Step T02: The light emitting diode lamp wirelessly receives a wireless signal from outside.

Step T04: The light emitting diode lamp determines whether the wireless signal comprises a wireless starting signal or not. If the wireless signal does not comprise the wireless starting signal, the burning address method goes to a step T06. If the wireless signal comprises the wireless starting signal, the burning address method goes to a step T08.

Step T06: The light emitting diode lamp does not perform (namely, omits) a burning procedure. Then the burning address method returns to the step T02.

Step T08: The light emitting diode lamp performs the burning procedure to convert a wireless address signal in/of the wireless signal into a local address data and stores the local address data into an address memory. After the light emitting diode lamp finishes the burning procedure, the burning address method goes to a step T10.

Step T10: A verification procedure is performed to wirelessly transmit the local address data stored in the address memory to a verification module.

Step T12: The verification module determines whether the local address data wirelessly received by the verification module is the same with the local address data in/of the wireless address signal or not. If the local address data wirelessly received by the verification module is the same with the local address data of the wireless address signal, the burning address method goes to a step T14. If the local address data wirelessly received by the verification module is not the same with the local address data of the wireless address signal, the burning address method goes to a step T16.

Step T14: The burning address method is finished. Or the burning address method for another light emitting diode lamp is performed.

Step T16: The verification module informs the light emitting diode lamp to eliminate the local address data stored in the address memory. Then the burning address method returns to the step T02.

It is noted that the steps T10˜16mentioned above are to verify whether the local address data is correct or not, but the steps T10˜16mentioned above are not essential steps of the burning address method of the present invention.

The advantage of the present invention is to burn the local address data208into the light emitting diode driving apparatus10which had been manufactured to store or change the local address data312, and the light emitting diode driving apparatus10can be burned repeatedly. Moreover, compared to the burning data being sent through the power carriers when burning, the present invention can avoid incorrectly determining the conventional carrier signals as the burning signal.
