[0044] In this example of execution, the bent arm 3 is divided into two parts such as bent-arm-type main body 301 and bent-arm-type cover plate 302, in order to realize visible wiring during the installation process of LED lighting device for the convenience of installation.

[0045] In this example of execution, top cover 1 is connected to one side of bottom case 2 through hinge 4. Therein, as in showed in Figure 2 to Figure 6, the end of hinge 4 is connected to the edge on outer side of bottom case 2, and a turn-over slot 204 is set up in the position on top of the edge of bottom case 2 corresponding to hinge 4, the other end of hinge 4 is connected to the inner side of top cover 1, so it realizes the connection of top cover 1 and bottom case 2; in this example of execution, a turn-over slot 204 is set up in bottom case 2, so it realizes the turn over of specified angle (such as 270°) of the connecting point of top cover land bottom case 2.

[0046] In a replaceable way, hinge 4 can be replaced with hinge module. Please refer to Figure 17 for the structural schematic diagram of an available type of hinge module. Hinge module 5 contains one hinge 51 of pivotal connection and one top cover hinge 52, therein, the hinge 51 contains the first connection sheet 511 and the first connection end 512, such hinge 51 is connected to bottom case 2 through the first connection sheet 511 in a fixed way; the top cover hinge 52 contains the second connection sheet 521 and the second connection end 522, such top cover hinge 52 is connected to the inner side of top cover 1 through the second connection sheet 521 in a fixed way; in addition, the first connection end 512 of hinge 51 is connected to the second connection end 522 of top cover hinge 52 through a pivotal connection end 53 in a pivotal way. Herein, it applies the hinge module containing hinge 51 and top cover hinge 52 to replace the hinge mentioned above, and the top cover turn-over will be more convenient after assembling top cover and bottom case.

[0047] Please refer to Figure 2, Figure 7 to Figure 11, toolless disassembly and assembly can be realized through a rotary switch for top cover 1 and the other side of bottom case, therein, the connecting points of hinge 4 & hinge module 5 and the connecting point of the rotary switch is set up on the two relative ends in the symmetric axis of the lamp housing.

[0048] Specifically, the rotary switch contains the first card 12 set up on top cover 1 while the second card 13 and rotary knob 14 set up on bottom case 2. As is showed in Figure 7, the first card 12 is fixed onto the inner side of top cover 1 through methods such as screw, and an arc-shape bayonet 121 is set up on the first card 12.

In this example of execution, toolless disassembly and assembly is realized through the connection of top cover 1 and bottom case 2 through the rotary knob, which brings convenient maintenance and greatly reduces the cost of maintenance.

[0049] In this example of execution and as is showed in Figure 9, there are a semi-limit structure 2011 and limit structure 2012 set up on the raised plane 201, the semi-limit structure 2011 and limit structure 2012 form a large circumferential angle and a small circumferential angle with the center of rotary knob 14, which is used for limiting the rotary stroke of the second card 13. Therein, the second card 13 is unable to turn over limit structure 2012 during the process of rotation; however, under the condition of applying force on the second card 13, it can turn over the semi-limit structure 2011; in a preferential way, the sliding contact surface of the semi-limit structure 2011 and the second card 13 has a certain gradient, for the convenience of the second card 13 overcoming the resistance smoothly to turn over the semi-limit structure 2011. Specific connecting mechanism of the first card 12 and the second card 13 is as follows:

[0050] As is showed in Figure 10, when top cover 1 and bottom case 2 are not connected, the second card 13 is located within the range of small circumferential angle formed by the connection between semi-limit structure 2011 & limit structure 2012 and the center of rotary knob 14, and it applies no force on the rotary knob 14 at this time, so it limits the rotary stroke of the second card within the space between semi-limit structure 2011 & limit structure 2012 during the idle state of the second card 13 and limits the second card 13 to rotate within a smaller range to prevent the inconvenience brought by the random rotation of the second card 13 when top cover 1 and bottom case are not connected.

[0051] As is showed in Figure 11, when top cover 1 and bottom case are connected, top cover 1 is covered on top of bottom case 2, and the first card 12 is right on top of the second card 13; it applies certain force on rotary knob 14 to drive the first card 12 to rotate and enables the first card 12 to turn over the semi-limit structure 2011 and to enter the bayonet 121, and it enables the first card 12 to turn to clamping state and then loosens the rotary knob 14; at this time, the first card 12 is located within the bayonet 121 and semi-limit structure 2011, and under the function of semi-limit structure 2011, it realizes the locking between the first card 12 and the second 13, to prevent loosening between top cover 1 and bottom case 2.
