In the step S5, the fixing post 131 is continuously rotated in the first direction C1, and the fixing post 131 is completely connected with the first electric connection slot 151 after the first electric connection part 143 and the second electric connection part 144 are connected with the second electric connection slot 152 and the third electric connection slot 153, respectively. In the step S6, the lamp 10 and the human sensing module 12 are installed on the main body 11.
FIG. 5 is a flowchart illustrating the step of fixing the pushing element on the fixing post in the lighting device assembling process according to an embodiment of the present invention. The step S1 comprises the following sub-steps S11˜S13. In the sub-step S11, the fixing post 131 is penetrated through the first case 111 and the first covering part 1121 from the first side of the main body 11. In the sub-step S12, the pushing element 132 is sheathed around the fixing post 131 from a second side of the first covering part 1121. In the sub-step S13, the pushing element 132 is rotated in a second direction C2 and fixed on the fixing post 131, so that the pushing element 132 is synchronously rotated and moved with the fixing post 131. An example of the pushing element 132 includes but is not limited to a nut. In another embodiment of the sub-step S12, the pushing element is disposed on the fixing post from the second side of the first covering part in a spot-welding manner or a snap-fitting manner. In case that the pushing element is disposed on the fixing post in the spot-welding manner, the pushing element is a solder bump. Whereas, in case that the pushing element is disposed on the fixing post in the snap-fitting manner, the pushing element is a snap-fit ring (also referred as an e-ring).
FIG. 6 is a flowchart illustrating the step of fixing the circuit module within the second case in the lighting device assembling process according to an embodiment of the present invention. The step S2 comprises the following sub-steps S21˜S23. In the sub-step S21, the circuit module 14 is disposed within the first covering part 1121 from the second side of the first covering part 1121, and the fixing element 131 in the receiving sleeve 1124 and the pushing element 132 are penetrated through the circuit module 14. In the sub-step S22, the first covering part 1121 and the second covering part 1122 are connected with each other. In the sub-step S23, the second covering part 1122 is fixed on the first covering part 1121 from the second side of the first covering part 1121, and the circuit module 14 is fixed within the first covering part 1121 and the second covering part 1122. That is, in the assembling process of the lighting device 1, the circuit module 14 is fixed within the second case 112 by the sub-steps S21 and S22.
In another embodiment, after the sub-step S21, the assembling process of the lighting device 1 further comprises the following steps. That is, a fixing glue is arranged between the fixing post 131 and the pushing element 132 to strengthen the connection between the pushing element 132 and the fixing post 131, so that the pushing element 132 is synchronously rotated with the fixing post 131. In this embodiment, the first direction C1 is a clockwise direction, and the second direction C2 is a counterclockwise direction. When the fixing post 131 is rotated in the clockwise direction, the fixing post 131 is moved in a direction toward the second side of the main body 11 (i.e. in a third direction C3) and the main body 11 is pushed by the fixing post 131 to be close to the backside plate 15. On the other hand, when the fixing post 131 is rotated in the counterclockwise direction, the fixing post 131 is moved in a direction toward the first side of the main body 11 (i.e. in a fourth direction C4) and the main body 11 is pushed by the pushing element 132 to be moved away from the backside plate 15.
That is, in the steps S3, S4 and S5 of the assembling process of the lighting device 1, the first case 111, the first covering part 1121 and the fixing module 13 are moved in the third direction C3. Moreover, the fixing post 131 is penetrated through the receiving sleeve 1124, so that the first segment 134 of the fixing post 131 is initially contacted and connected with the first electric connection slot 151. Meanwhile, the electric connection between the first segment 134 and the first electric connection slot 151 is established. Under this circumstance, as shown in FIG. 7, the first electric connection part 143 is not inserted into the second electric connection slot 152, and the second electric connection part 144 is not inserted into the third electric connection slot 153.
While the fixing post 131 is rotated and screwed into the first electric connection slot 151, the second case 112 is moved toward the backside plate 15, so that the first electric connection part 143 is inserted into the second electric connection slot 152 and the second electric connection part 144 is inserted into the third electric connection slot 153. Consequently, the electric connection between the first electric connection part 143 and the second electric connection slot 152 is established, and the electric connection between the second electric connection part 144 and the third electric connection slot 153 is established. As the fixing post 131 is continuously rotated and screwed into the first electric connection slot 151, the complete connection between the fixing post 131 and the first electric connection slot 151 is implemented (see FIGS. 8 and 9).
From the above discussions about the assembling process of the lighting device 1, the earth wire is first electrically connected with the power source, and then the live wire and the neutral wire are electrically connected with the power source. Consequently, the assembling process of the lighting device 1 can comply with safety regulations.
After the lighting device 1 is assembled by the above assembling process, the inner structure of the main body 1 of the lighting device 1 is shown in FIGS. 8 and 9. Please refer to FIGS. 8 and 9. When the circuit module 14 is fixed in the accommodation space 113 between the first covering part 1121 and the second covering part 1122, the first electric connection part 143 and the second electric connection part 144 are penetrated through corresponding fourth openings 1120 and protruded outside the second casing 112. When the first segment 134 is contacted with the first electric connection slot 151, it means that the fixing post 131 is initially connected with the first electric connection slot 151. At this moment, the electric connection between the fixing post 131 and the backside plate 15 is established. Moreover, when the pushing element 132 is contacted with the first electric connection slot 151, it means that the fixing post 131 is completely connected with the first electric connection slot 151. Moreover, when the fixing post 131 is moved toward the main body 11 and the pushing element 132 is not contacted the first electric connection slot 151 but the fixing post 131 is still contacted with the first electric connection slot 151, it means that the fixing post 131 is initially detached from the first electric connection slot 151. Moreover, when the fixing post 131 is moved toward the main body 11 and the fixing post 131 is not contacted with the first electric connection slot 151, it means that the fixing post 131 is completely detached from the first electric connection slot 151.
A disassembling process of the lighting device will be illustrated as follows. FIG. 10 is a flowchart illustrating a lighting device disassembling process complying with safety regulations according to an embodiment of the present invention. The lighting device disassembling process comprises the following steps S7˜S9.
In the step S7, the fixing post 131 is rotated in the second direction C2, so that the fixing post 131 is initially detached from the first electric connection slot 151. In the step S8, the fixing post 131 is continuously rotated in the second direction C2 and the pushing element 132 is contacted with the main body 11 in response to the rotation of the fixing post 131. Consequently, the main body 11 is detached from the backside plate 15, the first electric connection part 143 is detached from the second electric connection slot 152, and the second electric connection part 144 is detached from the third electric connection slot 153. In the step S9, the fixing post 131 is continuously rotated in the second direction C2, and the fixing post 131 is completely detached from the first electric connection slot 151 after the first electric connection part 143 is detached from the second electric connection slot 152 and the second electric connection part 144 is detached from the third electric connection slot 153.
In the step S7, while the fixing post 131 is rotated in the second direction C2, the pushing element 132 fixed on the fixing post 131 is moved in the fourth direction C4 to push the first covering part 1121 in the fourth direction C4. Moreover, since second covering part 1122 is fixed on the first covering part 1121, the second covering part 1122 and the circuit module 14 within the accommodation space 113 are moved with the first covering part 1121 in the fourth direction. Meanwhile, the fixing post 131 is initially detached from the first electric connection slot 151. However, the fixing post 131 is still electrically connected with the first electric connection slot 151, the first electric connection part 143 is still electrically connected with the second electric connection slot 152, and the second electric connection part 144 is still electrically connected with the third electric connection slot 153 (see FIG. 11). After the step S8 is performed, the first electric connection part 143 and the second electric connection part 144 are detached from the second electric connection slot 152 and the third electric connection slot 153, respectively. Then, the fixing post 131 is completely detached from the first electric connection slot 151 (see FIG. 12). From the above discussions, after the live wire and the neutral wire are electrically disconnected from the power source, the earth wire is electrically disconnected from the power source. Consequently, the disassembling process of the lighting device 1 can comply with safety regulations.
In the above embodiment, the step S6 is performed after the first case 111 and the backside plate 15 are combined together. It is noted that numerous modifications and alterations may be made while retaining the teachings of the invention. For example, in another embodiment, the lamp and the human sensing module are installed on the main body before the first case and the backside plate are combined together.
From the above descriptions, the present invention provides the lighting device. Through the fixing module, the main body is installed on the backside plate. While the fixing module is connected with the backside plate, the earth wire is firstly electrically connected with the power source. Then, during the process of assembling the fixing module with the backside plate, the live wire (or the neutral wire) of the circuit module is electrically connected with the power source. After the live wire (or the neutral wire) of the circuit module is electrically connected with the power source, the fixing module and the backside plate are completely combined with each other. In the disassembling process of the lighting device, the fixing module is initially disassembled from the backside plate while maintaining the electric connection between the fixing module and the backside plate. Moreover, while the electric connection between the fixing module and the backside plate is still established, the main body and the backside plate are structurally detached from each other, so that the live wire (or the neutral wire) of the circuit module is electrically disconnected from the power source. Then, the fixing module is disassembled from the backside plate, so that the main body and the backside plate are structurally detached from each other and the earth wire is electrically disconnected from the power source. By the structure of the lighting device of the present invention, the assembling process of the lighting device is simplified, and both of the assembling process and the disassembling process comply with safety regulations.
