[0024] One embodiment of this application provides an LED lamp, including a lamp housing, a light-emitting component 100, and a driver power supply 200. The lamp housing includes a metal back plate 300, a light-transmitting cover 400, and a cap 500. The LED lamp has a light-emitting side 101 and a backlight side 102. The metal back plate 300 and the light-transmitting cover 400 together form a cavity open at both ends. The light-emitting component 100 includes a substrate and LED beads disposed thereon. The light-emitting component 100 is disposed within the cavity and is arranged facing the light-transmitting cover 400. The cap 500 is used to close both ends of the cavity.

[0025] The metal backplate 300 is bent to form three recessed areas arranged side by side. The first recessed area 310 and the second recessed area 320 are located on either side, with their openings facing the light-emitting side 101. The third recessed area 330 is located between the first recessed area 310 and the second recessed area 320, with its opening facing the backlight side 102. The first recessed area 310 and the second recessed area 320 are used to mount the light-emitting component 100, and the third recessed area 330 is used to mount the driving power supply 200. Further, the LED lamp includes a drive cover 600 that cooperates with the third recessed area 330 on the backlight side 102 to shield the driving power supply 200. The drive cover 600 and the third recessed area 330 together form an open-end mounting space 610, which is closed by a cap 500.

[0026] The first recessed area 310 includes a first bottom wall 311 and two first side walls 312; the second recessed area 320 includes a second bottom wall 321 and two second side walls 322; and the third recessed area 330 includes a third bottom wall 331 and two third side walls 332. The first bottom wall 311, the second bottom wall 321, and the third bottom wall 331 are arranged in parallel. The first bottom wall 311 and the second bottom wall 321 are at the same height. When viewed from the backlight side 102, the third bottom wall 331 is lower than the first bottom wall 311 and the second bottom wall 321.

[0027] Specifically, the third bottom wall 331, a first side wall 312, and a second side wall 322 form the third recessed area 330. From another perspective, the two third side walls 332 also serve as the two side walls of the first recessed area 310 and the second recessed area 320, respectively. The light-emitting component 100 includes two parts respectively fixed to the first bottom wall 311 and the second bottom wall 321, and the driving power supply 200 is fixed to the third bottom wall 331.

[0028] The light-transmitting cover 400 includes a first light-transmitting cover 410 and a second light-transmitting cover 420, which form a first cavity 351 and a second cavity 352 with the first recessed area 310 and the second recessed area 320, respectively. The first recessed area 310, the second recessed area 320, and the third recessed area 330 have the same depth. The first light-transmitting cover 410 and the second light-transmitting cover 420 are plate-shaped structures, and both are flush with the third bottom wall 331.

[0029] The first sidewall 312 on the outer side is provided with a first flange 313 for fixing the first light-transmitting cover 410, and the second sidewall 322 on the outer side is provided with a second flange 323 for fixing the second light-transmitting cover 420. The two third sidewalls 332 are respectively provided with a first limiting portion 334 for mounting the first light-transmitting cover 410 with the first flange 313, and a second limiting portion 335 for mounting the second light-transmitting cover 420 with the second flange 323. The first limiting portion 334 and the second limiting portion 335 can be riveted to the corresponding rib strips of the two third sidewalls 332. The light-transmitting cover 400 is slidably mounted on the metal backplate 300. Specifically, the first flange 313 and the first limiting portion 334 form a first sliding groove for slidingly mounting the first light-transmitting cover 410, and the second flange 323 and the second limiting portion 335 form a second sliding groove for slidingly mounting the second light-transmitting cover 420.

[0030] The third bottom wall 331 forms a mounting surface 333 on the light-emitting side 101, which is flush with both the first light-transmitting cover 410 and the second light-transmitting cover 420. The third bottom wall 331, as part of the metal back plate 300, has its mounting surface 333 directly exposed to the light-emitting side 101. The LED luminaire includes a sensor 301 for use with it. The mounting surface 333 has a base 336 for connecting the sensor 301. The sensor 301 may be designed based on infrared sensing principles, for example. The base 336 may have a mounting hole 337 that threadedly engages with the sensor 301. The LED luminaire also includes a dustproof component 302 that seals the mounting hole 337 before installing the sensor 301. The dustproof component 302 is flush with the mounting surface 333 to prevent damage to the outer packaging of the LED luminaire from the protruding sensor 301 during transportation. At the installation site, users can select sensors with different sensing functions according to their different sensing functions. After removing the dustproof part 302, the selected sensor is assembled into the mounting hole 337.

[0031] The mounting surface 333 has a recess 338 for assembling the base 336, making both the base 336 and the mounting surface 333 flush. The sensor 301 and the base 336 are threaded together and electrically connected simultaneously after installation. The resistance to disengaging the sensor 301 from the base 336 is less than the resistance to disengaging the base 336 from the recess 338, preventing the base 336 from rotating during sensor 301 installation. Specifically, the recess 338 has a threaded hole 339, the internal thread of which is circumferentially interrupted, for example, formed by two D-shaped holes connected together. Correspondingly, the base 336 has a circumferentially interrupted external thread to achieve an interference fit between the base 336 and the recess 338.

[0032] The third recessed area 330 of this application is used to install the driver power supply 200, which reduces the space occupied by the driver power supply 200 and makes the LED lamp thinner. The first recessed area 310, the second recessed area 320 and the third recessed area 330 are formed by bending a metal back plate 300, which facilitates processing and assembly and improves the structural stability of the lamp housing.

[0033] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0034] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
