[0024] See Figures 1-5 In view of the technical problem that the replacement of the light-transmitting part is cumbersome in the prior art, one embodiment of this application provides an LED lamp, which includes a lamp housing and a light-emitting component 100.

[0025] The lamp housing includes a back cover 200, a light-transmitting part 300, and a sealing part 400. The light-transmitting part 300 may be, for example, a light-transmitting cover with a desired light emission angle. The back cover 200 and the light-transmitting part 300 slide together and enclose each other to form a cavity 150 open at both ends. The back cover 200 is provided with a groove 210 for sliding with the light-transmitting part 300. The groove 210 is formed by folding the back cover 200 and / or adding a pressure rib. The light-emitting component 100 is disposed in the cavity 150 and arranged directly opposite the light-transmitting part 300. The cavity 150 may include, for example, multiple cavities arranged in parallel. The light-emitting component 100 includes a substrate and LED beads disposed on the substrate.

[0026] The sealing portion 400 is used to close both ends of the cavity 150, and is fixed to the back cover portion 200 to support the cavity. Of the two sealing portions 400 used to close the cavity 150, at least one sealing portion 400 has a clearance notch 410 that allows the light-transmitting portion 300 to slide out of the back cover portion 200. The clearance notch 410 is located on one side of the extending direction of the groove 210. Unless otherwise specified, the sealing portion in the following embodiments refers to the sealing portion with the clearance notch 410. The groove 210 of the back cover portion 200 is open along the extending direction of the cavity, and the height of the sealing portion 400 is lower than the open side of the groove 210 to form the clearance notch 410. The sealing portion 400 has an inwardly folded edge to support the sliding of the light-transmitting portion 300 within the groove 210. Furthermore, the sealing part 400 has a guide part 420 that guides the light-transmitting part 300 to slide out of the clearance notch 410. The guide part 420 is formed by an inwardly folded edge of the sealing part 400. Sliding out refers to the process by which the light-transmitting part 300 slides out of the LED light fixture after installation.

[0027] In some embodiments, the blocking portions 400 at both ends of the cavity 150 are provided with clearance notches 410, and the blocking portions 400 at both ends of the cavity 150 are provided with guide portions 420. When the light-transmitting portion 300 slides into the groove 210, the guide portion 420 of the blocking portion 400 at the end of the sliding path is used to guide the light-transmitting portion 300 to the corresponding clearance notch 410.

[0028] The LED luminaire includes a shielding member 500 that detachably covers and avoids the notch 410 to prevent the light-transmitting part 300 from slipping. The sealing part 400 is a structural portion used to seal the cavity 150, and the shielding member 500 completely covers the sealing part 400. A connecting part 430 is provided between the sealing part 400 and the back cover part 200 to fix them together. This connecting part 430 forms a raised area 450 relative to the sealing part 400, ensuring that the side of the LED luminaire remains flat after the shielding member 500 is assembled. The sealing part 400 and the connecting part 430 can be integrally formed, and the connecting part 430 is fixed to the back cover part 200 by fasteners such as bolts.

[0029] The LED light fixture includes a locking member 600 that locks a shielding member 500 onto the lamp housing. A locking part 440, which cooperates with the locking member 600, is provided on the sealing part 400. Specifically, the locking part 440 is a lock hole 441 formed in the sealing part 400. The locking member 600 is movably disposed inside the shielding member 500 and includes an unlocking part 610 exposed on the outside of the shielding member 500. An unlocking indicator 501, indicating the switching of the unlocking part 610's working state, is provided on the outside of the shielding member 500. During use, the user can drive the unlocking part 610 to release the locking member 600 and remove the shielding member 500 from the lamp housing, based on the unlocking indicator 501. A locking indicator can also be provided on the outside of the shielding member 500 to mark that the locking member is currently in a locked state.

[0030] See Figures 6-10 The locking member 600 has a locked position 601 and an unlocked position 602, and the locking member 600 always tends to move from the unlocked position 602 to the locked position 601. The LED lamp includes an elastic member 620 acting on the locking member 600, the elastic member 620 being, for example, a retaining spring, the elastic member 620 acting on the locking member 600 causing the locking member 600 to always tend to move from the unlocked position 602 to the locked position 601. The locking member 600 has an inclined surface 630 that abuts against the lamp housing and drives the locking member 600 from the locked position 601 to the unlocked position 602.

[0031] The locking member 600 includes an unlocking part 610 located outside the shielding member 500 and a locking part 640 located inside the shielding member 500. The locking member 600 is slidably mounted on the shielding member 500. Specifically, the shielding member 500 has a mounting hole 510, and the locking part 640 has an elastic part 650 that guides itself into the mounting hole 510 and clamps the edge of the mounting hole 510. The elastic part 650 and the unlocking part 610 clamp the edge of the mounting hole 510 and slide in cooperation with the edge of the mounting hole 510, so that the locking part 640 is slidably mounted on the shielding member 500. A limiting groove 660 is provided between the locking part 640 and the unlocking part 610 for cooperating with the edge of the lock hole 441 to prevent the locking part 640 from disengaging from the lock hole 441. The locking part 640 has a sleeve post 641 for the elastic member 620 to be sleeved and supported. The locking part 640 maintains its cooperation with the locking part 440 under the action of the elastic member 620. Furthermore, the locking part 440 includes two locations, and the locking element 600 correspondingly includes two locations. The unlocking part 610 of the locking element 600 can be, for example, a DIP switch, and the locking element 600 can be, for example, a DIP switch.

[0032] When locked, the user presses the shielding member 500 into the lamp housing until the inclined surface 630 contacts the edge of the lock hole 441. The contact between the inclined surface 630 and the edge of the lock hole 441 drives the locking part 640 to move from the locked position 601 to the unlocked position 602. Then the locking part 640 enters the lock hole 441. Under the action of the elastic member 620, the locking part 640 returns to the locked position 601 and is restricted by the edge of the lock hole 441 to the inside of the blocking part 400, thus completing the locking of the locking part 640 relative to the locking part 440, and at the same time completing the locking of the shielding member 500 relative to the blocking part 400.

[0033] To unlock, the user presses the unlocking part 610 on the outside of the locking member 600, causing the locking part 640 to move from the locked position 601 to the unlocked position 602 along with the locking member 600, thus completing the unlocking. Additionally, the shielding member 500 can be removed to expose the clearance notch 410, facilitating the removal of the light-transmitting part 300.

[0034] See Figure 1 , Figure 3 , Figure 4 and Figure 11 The LED lighting fixtures provided in the embodiments of this application can be used as high-bay lighting fixtures. For fixture assembly: see... Figure 1 and Figure 3 The light-emitting component 100 is assembled and fixed to the back cover portion 200, and the two ends of the cavity 150 are sealed with the sealing portion 400. See also Figure 3 and Figure 4The light-transmitting part 300 is slidably inserted into the groove 210 of the back cover part along the clearance notch 410 of the sealing part 400. Then, the shielding member is detachably connected to the lamp housing and covers the clearance notch 410. Specifically, the shielding member 500 is locked to the locking part 440 on the sealing part 400, thus completing the shielding of the groove 210 by the shielding member 500 and preventing the light-transmitting part 300 from sliding out of the groove 210, thereby forming... Figure 11 The assembly state is shown. When it is necessary to replace the light-transmitting part 300, the shielding part 500 is unlocked and removed. At this time, the light-transmitting part 300 can slide freely into or out of the slide groove 210, which is convenient for replacing the light-transmitting part 300 with different light-emitting angle structures.

[0035] 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.

[0036] 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.
