For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] See also Figure 1 In one embodiment of the present application, a lamp is provided. The lamp includes a base 100 fixed to a support and a lamp body connected to the base 100. Figure 1 The housing 200 of the lamp body is shown. The support may be a building or an intermediate object fixed to the building, for example, the support may be a ceiling or a mounting plate or a Bagua plate fixed to the ceiling. The base 100 is provided with a first type of mounting hole 101 for direct mounting on a building, and a second type of mounting hole 102 for indirect mounting on a building. During installation, the base 100 is mounted on the ceiling through the first type of mounting hole 101, or the base 100 is mounted on the Bagua plate through the second type of mounting hole 102. After the base 100 is installed, the base 100 and the lamp body can be connected by a safety rope to prevent the lamp from accidentally falling and causing personal injury and property loss. After power is turned on, the lamp body is snapped onto the base 100 to complete the installation of the lamp.

[0035] See also Figure 2 and Figure 3 The lamp body includes a housing 200, a light emitting assembly 300 disposed inside the housing 200, and a driving power supply 400 disposed outside the housing 200 and electrically connected to the light emitting assembly 300. The housing 200 includes a back plate 210 and a lampshade 220, and the light emitting assembly 300 includes an LED lamp bead 310 and a substrate 320 for mounting the light emitting LED. The driving power supply 400 includes a circuit board and electronic components disposed on the circuit board, and the driving power supply 400 is electrically connected between the light emitting assembly 300 and an external power supply to supply power to the light emitting assembly 300.

[0036] When the lamp provided in this embodiment is used and installed by the user, the lamp cover 220 does not need to be opened, and the driving power supply 400 can be directly connected to the concave 212 of the back plate 210. When the driving power supply 400 needs to be repaired or replaced, the base 100 can be kept on the support and the lamp body can be separated from the base 100. Since the driving power supply 400 is arranged outside the lamp body housing 200, when checking the driving power supply 400, it is not necessary to disassemble the lamp body housing 200, which is convenient for repairing and replacing the driving power supply 400.

[0037] See also Figures 4 to 6The back plate 210 includes a mounting surface 211 close to the support when installed, and the mounting surface 211 has a recess 212 for accommodating the driving power supply 400. Since the driving power supply 400 is accommodated in the recess 212, when the side of the back plate 210 away from the light-emitting component 300 faces the building, the driving power supply 400 is difficult to be perceived by sight, thereby ensuring the aesthetics of the lamp body. Of course, the recess 212 can also be installed to accommodate other electronic devices such as emergency power supply, emergency drive, sensor, etc. The emergency power supply can adopt an integrated internal battery style or a split external battery style.

[0038] It can be understood that the back plate 210 provided in this embodiment is not strictly limited to a flat plate structure, and the concept of the back plate 210 is only used to distinguish the lampshade 220. The back plate 210 is formed by bending a metal plate (sheet metal process) and has folded edges 213 located on both sides of the mounting surface 211 for buckling the lampshade 220. The lampshade 220 can be a prism cover, and the lampshade 220 is semi-enclosed around the lamp body, which improves the aesthetics of the lamp body, which can be called a "wraparound" product design.

[0039] The lamp body is in the shape of a long strip, with a length direction L and a width direction W. The back plate 210 and the lampshade 220 enclose a cavity 214 extending along the length direction L of the lamp body. The housing 200 further includes end caps 230 disposed at both ends to block the cavity 214. The end caps 230 can be fixed to the housing 200 by riveting. The end caps 230 can be provided with knock-off holes 231 for easy knock-off, so as to facilitate the optional installation of the sensor. Both the back plate 210 and the end caps 230 can be made by sheet metal technology to avoid collapse during use.

[0040] The recess 212 has a bottom wall 215 and a side wall 216, and the cross section is as follows: Figure 5 In the trapezoidal structure shown, the recess 212 extends between the two end caps 230. The light emitting assembly 300 is specifically arranged on the surface of the bottom wall 215 facing the lampshade 220. The base 100 has a flange 110 that guides itself into the recess 212 to engage with the lamp body, and the flange 110 specifically extends along the length direction L of the lamp body.

[0041] See also Figure 7 A clamping piece 240 connected to the base 100 is disposed in the recess 212. The clamping piece 240 extends along the width direction of the lamp body and crosses the recess 212. The clamping piece 240 can be considered as a cross-bracing bracket, on which a clamping groove 241 is disposed. In coordination, a clamping tongue 120 is provided on the base 100, and the two are clamped together to realize a detachable connection between the base 100 and the clamping piece 240.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0043] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
