Preferably, the fastener 223 is a butterfly bolt. The first fastening hole 255 is a through hole and the second fastening hole 256 is a threaded hole. After the butterfly bolt passes through the first fastening hole 255, it threads into the second fastening hole 256.
Therefore, the lamp fixing member 220 of this embodiment is different from Embodiments I to III in that:
1. The lamp fixing member 220 and the lamp body 210 of Embodiments I to III have two assembly modes: Firstly, the lamp fixing member 220 and the lamp body 210 are assembled as a whole, and then the lamp fixing member 220 is connected and fixed on the keel member 110. For example, in Embodiment I, the first fixing member 221 is fitted to one side of the keel member 110, and then the second fixing member 222 is pivoted to form a connection relationship. Then the fifth arm part 252 of the second fixing member 222 is tightened relative to the fourth arm part 251 by screwing the fastener 223, so as to realize the purpose of connecting and fixing the lamp fixing member 220 on the keel member 110. For another example, in Embodiment II, the first arm part 241 of the first fixing member 221 is fitted to one side of the keel member 110, and then the second fixing member 222 is pressed and buckled downward. The sixth arm part 261 and the seventh arm part 262 of the second fixing member 222 respectively act on both sides of the keel member 110 to realize the purpose of connecting and fixing the lamp fixing member 220 to the keel member 110. For another example, in Embodiment III, in addition to the steps in Embodiment II, the sixth arm part 261 and the seventh arm part 262 are relatively tightened by providing fasteners 223 to realize the purpose of connecting and fixing the lamp fixing member 220 on the keel member 110.
Secondly, the two steps of the first assembly method can also be reversed, i.e. connecting and fixing the lamp fixing member 220 to the keel member 110, and then assembling and connecting the lamp fixing member 220 with the lamp body 210. The specific contents are the same as those of the first assembly method and will not be repeated here.
2. In this embodiment, the fixed connection of the lamp body 210 can only be completed by connecting and fixing the lamp fixing member 220 to the keel member 110 first, and then assembling and connecting the lamp body 210 with the lamp fixing member 220. Here, the preliminary positioning is completed after the lamp fixing member 220 and the keel member 110 are assembled. After that, the fastener 223 can be screwed first to completely fix it, and then the lamp body 210 and the lamp fixing member 220 can be assembled and connected. Alternatively, after the preliminary positioning, the lamp body 210 and the lamp fixing member 220 can be assembled and connected first, and then the fastener 223 can be screwed to fully fix the lamp 200.
