## Background
CROSS REFERENCE TO RELATED APPLICATION
This application also claims priority to Taiwan Patent Application No. 103139619 filed in the Taiwan Patent Office on Nov. 14, 2014, the entire content of which is incorporated herein by reference.
TECHNICAL FIELD
The present disclosure relates to a lighting device, in particular to a wired/wireless lighting device capable of receiving control signals by wired transmission and wireless transmission to control the luminous status of the lighting device. The present disclosure further relates to a lighting control system having the lighting device.
BACKGROUND
Generally speaking, the lighting devices of most of office buildings, factories and dwelling houses are controlled by a wired lighting control system; in other words, the lighting devices are usually controlled by the lighting switches installed on the wall. Thus, if the user wants to turn on or turn off the lighting device at a specific position, or adjusts its brightness, the user only needs to walk to the switch corresponding to the lighting device and then the user can operate the lighting device. Therefore, the wired lighting control system can help the user conveniently operate the lighting device; however, if there are many lighting devices distributed at different positions over a large area, the user cannot operate all of these lighting devices in a short time; in this case, the wired lighting control system is not very convenient for the user.
As a result, the wireless lighting control system was developed so as to solve the above problem. For example, U.S. Pat. No. 8,110,996 disclosed a modular wireless lighting control system, which uses a central computer to transmit control signals to multiple transceivers via wireless network so as to control all lighting devices inside a building. Although the wireless lighting control system does not need complicated wiring and can control a large number of lighting devices in a short time. However, as the wireless lighting control system needs to transmit control signals via the wireless network, but the wireless network is not always stable; therefore, once the wireless network is disconnected, the user absolutely cannot control these lighting devices. Thus, the reliability of the wireless lighting control system still needs to be improved.
In addition, the practicality of the wireless lighting control system is still in dispute. For example, in general, after a user returns to home from work, the user will directly turn on the lighting devices by the switches installed on the wall; under above circumstance, it will be very inconvenient for the user to use a mobile phone, a computer or other wireless control devices to control the lighting devices in the house. On the contrary, when the user is going to sleep, the user will usually use a wireless control device to turn off all lighting devices in the house at a time. For the reason, the house only having the wireless lighting control system cannot conform to the habits of most users without further improvements. As described above, the wired lighting control system and the wireless lighting control system have their advantages, but they still have shortcomings which need to be overcome.
Accordingly, it has become an important issue to provide a lighting control system and the corresponding lighting device capable of not only achieving the advantages of both of the wired lighting control system and the wireless lighting control system, but also improving their shortcomings.

The differences between the embodiment and the previous embodiment are that the power converting module of the embodiment may be an electrical ballast 111a, and the lighting module may be a gas-discharge lamp 112a. 
The electrical ballast 111a may be coupled to the gas-discharge 112a, the wireless receiving module 113 and the wired receiving module 114. More specifically, the wireless receiving module 113 may be detachably coupled to the electrical ballast 111a by a connector; the connector may be, for example, a USB (Universal Serial Bus) interface. Besides, the gas-discharge lamp may be, for example, a mercury lamp, a metal halide lamp, a sodium lamp, a fluorescent lamp, or a xenon lamp.

Please refer to FIG. 3, which is the schematic view of the second embodiment of the lighting control system in accordance with the present invention. As shown in FIG. 3, the lighting control system 1 may include a lighting device 11, a wired control module 12 and a wireless control module 13; the lighting device 11 may include a power converting module, a lighting module, a wireless receiving module 113 and a wired receiving module 114.

It is worthy to point out that the conventional wired lighting control system can only allow the user to manually operate the switches on the wall to control the lighting devices; therefore, if there are many lighting devices in the building, it is impossible for the user to swiftly and efficiently control these lighting devices. In addition, the conventional wireless lighting control system allows the user to swiftly and efficiently control many lighting devices; however, the conventional wireless lighting control system cannot conform to the habits of most users, so its practicality is still in dispute. On the contrary, the lighting control system according to the embodiments of the present invention can effectively integrate the wireless lighting control system and the wired lighting control system via special design, so the user can choose whether to wiredly or wirelessly control the lighting devices according to actual requirements. For example, after the user returns to home from work, the user can directly turn on the lighting devices by the switches installed on the wall; when the user is going to sleep, the user can directly use his cell phone to turn off all lighting devices in the house at a time. As described above, the lighting control system according to the embodiments of the present invention can not only swiftly and efficiently control a lot of lighting devices, but also can conform to the habits of most users under certain circumstances. Thus, the lighting control system according to the embodiments of the present invention can achieve higher practicality.

Accordingly, the lighting control system according to the embodiments of the present invention can achieve higher reliability.
In addition, the wireless receiving module of the lighting device according to the embodiments of the present invention can be detachably coupled to the power converting module via a connector. Therefore, the wireless receiving module and the lighting device can be different products for sales, and the user also can determine whether to purchase the wireless receiving module or not according to his requirements. Thus, the lighting device according to the embodiments of the present invention can be more flexible in use and of high commercial value. As described above, the present invention definitely has an inventive step.

The power circuit unit 1112 of the power converting module 111 may be coupled to a power supply to receive the power input signal PI from the power supply in order to supply power to the lighting module 112, the wireless receiving module 113, and the wired receiving module 114. The wired receiving module 114 may receive a first control signal C1 transmitted from the wired control module 12, and convert the first control signal C1 into a first converted control signal which can be read by the processing unit 1111; then, the wired receiving module 114 may transmit the first converted control signal to the processing unit 1111. The wireless control module 13 may transmit a second control signal C2 via various wireless transmission technologies; the wireless receiving module 113 may receive the second control signal C2 and convert the second control signal C2 into a second converted control signal which can be read by the processing unit 1111; then, the wireless receiving module 114 may transmit the second converted control signal to the power converting module 111. Afterward, the processing unit 1111 may transit a control signal CS to the power circuit unit 1112, and then the power circuit unit 1112 may transmit a feedback signal to the processing unit 1111; in this way, the processing unit 1111 may control the lighting module 112 via the power circuit unit 1112 according to the first control signal C1 and the second control signal C2.
Therefore, the user can wiredly transmit the first control signal C1 to the wired receiving module 114 via the wired control module 12, and convert the first control signal C1 into the first converted control signal which can be read by the processing unit 1111; then, the first converted control signal can be transmitted to the processing unit 1111 so as to control the lighting module 112.
