Description

BACKGROUND OF THE PRESENT DISCLOSURE

Field of the Present Disclosure

The present disclosure relates to a light emitting diode (LED) lamp, and especially relates to a light emitting diode (LED) lamp receiving a burning signal including a burning activation data and a burning address data in different manners.

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.

However, the present disclosure is not limited by the above-mentioned manners of transmitting the light control data and the devices operated by the user.

FIG. 9A shows a block diagram of a first embodiment of using a burning signal according to the present disclosure. The LED lamp 10C (i.e., the LED module 10C) includes at least one LED 11C and an LED driver 12C. The LED driver 12C includes at least two terminals C1,C2/C1,C2,C3 (detailed as follows), a burning processor 127C, and an address memory 124. In this embodiment, a first terminal C1 (i.e., a power input terminal) and a second terminal C2 (i.e., a power output terminal) are externally coupled to a power line PL. The LED driver 12C receives the required power through the power line PL.

The burning processor 127C receives a burning activation data Sact of a burning signal through the first terminal C1 or the second terminal C2 from the power line PL, and directly and externally receives a burning address data Sadd of the burning signal without from the power line PL. When a burning function of the burning processor 127C is activated by the burning activation data Sact, the burning processor 127C converts the burning address data Sadd into a local address data 312 and burns the local address data 312 into the address memory 124 so that the LED lamp 10C operates in a burning mode. After the local address data 312 are completely burned into the address memory 124, the LED lamp 10C operates in a lighting mode from the burning mode.

In one embodiment, the burning processor 127C includes a burning signal receiver 128C and a burning address controller 126C. As shown in FIG. 9A, the burning signal receiver 128C receives the burning activation data Sact and the burning address data Sadd. The burning address controller 126C is coupled to the burning signal receiver 128C and the address memory 124. When the burning address controller 126C receives the burning activation data Sact to activate the burning function, the burning address controller 126C receives the burning address data Sadd, converts the burning address data Sadd into the local address data 312, and burns the local address data 312 into the address memory 124.

The LED driver 12C further includes a lighting processor 140C. The lighting processor 140C is responsible for lighting control, lighting processing, and so forth. The lighting processor 140C is externally connected to the power PL, and receives a lighting signal with an address data and a lighting data through the power line PL. When the burning function of the burning processor 127C is activated, the lighting processor 140C is disabled. On the contrary, after the local address data 312 are completely burned into the address memory 124, the burning processor 127C is disabled and the lighting processor 140C drivers the at least one LED 11C to work in the lighting mode according to the lighting signal.

In particular, when the burning signal receiver 128C determines that a voltage of the burning address data Sadd is greater than a first predetermined threshold voltage, the burning address controller 126C receives the burning address data Sadd. In addition, when the burning signal receiver 128C determines that a voltage of the burning activation data Sact is greater than a second predetermined threshold voltage, the burning address controller 126C activates the burning function.

In this embodiment shown in FIG. 9A, the burning processor 127C receives the burning activation data Sact in a contact manner from the power line PL, and receives the burning address data Sadd in a contactless manner, that is, the burning activation data Sat is a carrier-wave data, and the burning address data Sadd may be, for example but not limited to, a radio-wave data or a light-wave data.
