Detailed implementation manners

[0028] The present invention will be further described in detail below with reference to the drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0029] As Figures 1 to 8 shown, a wall washer lamp that is convenient for installation and disassembly described in this embodiment includes a mounting base 1 and a lamp body part 2 provided on the mounting base 1. The mounting base 1 is provided with two mounting holes 11 arranged at intervals. Nuts 12 are rotatably provided at positions corresponding to the two mounting holes 11 on the mounting base 1. The mounting base 1 is further provided with an anti-reversal mechanism that can unidirectionally lock the nuts 12 in an unlockable manner; by unidirectionally locking the nuts 12 through the anti-reversal mechanism, when the nuts 12 are in the locked state, they can only rotate forward and cannot rotate backward. When the anti-reversal mechanism releases the unidirectional lock on the nuts 12, the nuts 12 can rotate forward and backward;

[0030] The lamp body part 2 is provided with studs 241 corresponding to the two mounting holes 11 one by one. The studs 241 are movably inserted through the mounting holes 11 and are threadedly connected to the corresponding nuts 12. When the studs 241 move along the axis of the nuts 12, the studs 241 utilize the thread fit between them and the nuts 12 to drive the nuts 12 to rotate.

[0031] Specifically, when the wall washer lamp described in this embodiment is used, the mounting base 1 is fixed on the wall, and then the two studs 241 of the lamp body 2 are correspondingly inserted into the two nuts 12, and the lamp body 2 is pressed down. Since the anti-reversal mechanism locks the nuts 12 in one direction, the two nuts 12 rotate forwardly under the drive of the screw rod 225, and the screw rod 225 penetrates into the mounting hole 11, so that the lamp body 2 is installed on the mounting base 1, and the installation of the wall washer lamp is completed; when the screw 225 needs to be pulled out from the mounting hole 11, the screw rod 225 is pulled out of the mounting hole 11. 225 drives the nut 12 to rotate in the opposite direction. At this time, due to the action of the anti-reversal mechanism, the nut 12 is one-way locked, so that the nut 12 cannot rotate in the opposite direction. This can prevent the lamp body part 2 from loosening from the mounting base 1, and the structure is more reliable. At this time, the anti-reversal mechanism releases the one-way lock of the nut 12. After the lock is released, the nut 12 can rotate in the opposite direction under the drive of the screw 225, so that the lamp body part 2 can be removed. This makes disassembly and assembly convenient, and there is no need to remove the mounting base 1, thereby effectively avoiding secondary damage to the wall.

[0032] like Figures 1 to 3 As shown, the wall washer lamp described in this embodiment, in some embodiments, the anti-reversal mechanism includes a ratchet 131 sleeved on the outer wall of one of the nuts 12, a sliding seat 132 slidably connected to the mounting base 1, and a tension spring 133 connected between the sliding seat 132 and the mounting base 1, the sliding seat 132 is roughly L-shaped, and a pawl 134 is provided at one end of the sliding seat 132, and the pawl 134 maintains unidirectional engagement with the ratchet 131 under the action of the tension spring 133.

[0033] In actual application, when the screw 225 drives the nut 12 to rotate forward, the nut 12 drives the ratchet 131 to rotate; when the screw 225 drives the nut 12 to rotate reversely, the pawl 134 locks the ratchet 131 in one direction to prevent the ratchet 131 from rotating reversely; when the lamp body part 2 needs to be disassembled, the sliding seat 132 is pushed to slide, and the sliding seat 132 drives the pawl 134 to move away from the ratchet 131, and the tension spring 133 is stretched, so that the pawl 134 is disengaged from the one-way engagement with the ratchet 131, thereby releasing the one-way lock on the nut 12, so that the nut 12 can drive the ratchet 131 to rotate reversely under the drive of the screw 225; when the force on the sliding seat 132 is released, the sliding seat 132 is reset under the force of the tension spring 133, driving the pawl 134 to move toward the ratchet 131, so that the pawl 134 is once again engaged with the ratchet 131 in one direction.

[0034] like Figures 1 to 3As shown, for the wall washer light in this embodiment, in some embodiments, the mounting base 1 is provided with a U-shaped groove 15. The mounting hole 11 penetrates through the mounting base 1 from the bottom of the U-shaped groove 15. The nut 12 is arranged on the bottom of the U-shaped groove 15. A sliding groove 16 is formed in one side wall of the U-shaped groove 15. One end of the sliding seat 132 extends into the U-shaped groove 15 movably. The other end of the sliding seat 132 is slidably connected in the sliding groove 16 and protrudes outside the mounting base 1 for toggling the sliding seat 132. The tension spring 133 is connected to the other end of the sliding seat 132.

[0035] It can be understood that in this embodiment, by providing the U-shaped groove 15, the lamp body part 2 extends into the U-shaped groove 15, enhancing the support of the mounting base 1 for the lamp body part 2 and making the fixation more reliable. By providing the sliding groove 16, it is convenient for the installation of the sliding seat 132 and also facilitates the stroke limitation of the sliding seat 132 to prevent damage to the tension spring 133 due to excessive stroke of the sliding seat 132.

[0036] As Figure 1 、 Figure 2 and Figures 4 to 6 shown, for the wall washer light in this embodiment, in some embodiments, the lamp body part 2 includes a first lamp housing 21 and a light-emitting lamp body slidably arranged in the first lamp housing 21. A first air chamber 23 is formed between the light-emitting lamp body and the first lamp housing 21. A second air chamber 221 that can communicate with the first air chamber 23 is provided in the light-emitting lamp body. A light-emitting unit 222 and a temperature sensor 223 are provided in the second air chamber 221. A transmission cylinder 211 is provided in the first lamp housing 21;

[0037] The light-emitting lamp body includes a motor 224 and a screw rod 225. One end of the screw rod 225 is connected to the output end of the motor 224, and the other end of the screw rod 225 is threadedly connected to the inner wall of the transmission cylinder 211.

[0038] Specifically, in this embodiment, the first air chamber 23 is provided with a first one-way valve 25 that makes the first air chamber 23 conduct unidirectionally with the outside atmosphere, and the light-emitting lamp body is provided with a second one-way valve 226 that makes the second air chamber 221 conduct unidirectionally with the outside atmosphere.

[0039] It can be understood that generally, the light-emitting unit 222 of the wall washer has a relatively high power and high waterproof requirements, so its sealing performance is relatively high and its heat dissipation performance is poor. A temperature sensor 223 is provided inside the wall washer. When the temperature inside the wall washer reaches the set temperature, the temperature sensor 223 inside the wall washer generates an induction signal, and the motor 224 starts to operate. By setting its operating time, the positive and reverse rotation of the screw 225 is switched. Since the screw 225 is threadedly connected to the transmission cylinder 211, when the screw 225 rotates, the screw 225 drives the entire light-emitting lamp body to slide relative to the first lamp housing 21, so that the light-emitting lamp body reciprocates. When the light-emitting lamp body extends relative to the first lamp housing 21, the effective volumes of the first air chamber 23 and the second air chamber 221 increase, the pressure decreases, and the first one-way valve 25 opens. External gas enters the first air chamber 23 through the first one-way valve 25. When the light-emitting lamp body retracts relative to the first lamp housing 21, the effective volumes of the first air chamber 23 and the second air chamber 221 are compressed, the pressure increases, the second one-way valve 226 is opened, and the gas in the second air chamber 221 is discharged to the outside. In this way, gas circulation is formed to reduce the temperature in the second air chamber 221, achieving the effect of dissipating heat from the light-emitting unit 222. Such a reciprocating cycle constitutes the gas circulation inside the lamp body part 2, continuously cooling down.

[0040] As Figure 1 , Figure 2 and Figures 4 to 7 shown in the wall washer described in this embodiment, in some embodiments, a receiving groove 212 is concavely provided on one side of the first lamp housing 21. A fixing plate 24 fixedly sleeved on the outer wall of the transmission cylinder 211 is provided in the receiving groove 212. Two stud bolts 241 penetrating through the other side of the first lamp housing 21 are convexly provided at intervals on the fixing plate 24. By providing the receiving groove 212 in this embodiment, the installation of the light-emitting lamp body is facilitated. The fixing plate 24 is arranged in the receiving groove 212, and the two stud bolts 241 are arranged on the fixing plate 24. After the stud bolts 241 are threadedly connected to the nuts 12, the installation of the lamp body part 2 can be realized.

[0041] As Figure 1 , Figure 2 and Figures 4 to 6 shown in the wall washer described in this embodiment, in some embodiments, the light-emitting lamp body further includes a second lamp housing 227. The second lamp housing 227 is provided with an avoidance hole for the transmission cylinder 211 to pass through. The avoidance hole communicates the first air chamber 23 and the second air chamber 221. The motor 224 is installed on the second lamp housing 227, and the screw 225 rotates and passes through the avoidance hole. In this embodiment, the second lamp housing 227 is further provided with a third one-way valve 229 for making the second air chamber 221 communicate with the first air chamber 23 unidirectionally.

[0042] It can be understood that when the transmission cylinder 211 penetrates into the avoidance hole, the first air chamber 23 and the second air chamber 221 can communicate through the avoidance hole. As the light-emitting lamp body slides, the transmission cylinder 211 gradually extends into the avoidance hole, which will cause the connectivity between the second air chamber 221 and the first air chamber 23. At this time, under the pressure in the first air chamber 23, the third one-way valve 229 opens to ensure the communication between the second air chamber 221 and the first air chamber 23, so as to dissipate heat from the second air chamber 221.

[0043] In some embodiments of the wall washer lamp described in this embodiment, the light-emitting unit 222 is rotatably arranged in the second air chamber 221. Protective glasses are provided on opposite sides of the second lamp housing 227. One end of the light-emitting unit 222 is connected with a turbine 228 meshing with the screw 225. An avoidance notch 213 is formed in the side wall of the transmission cylinder 211 along its length direction.

[0044] In actual use, the motor 224 can drive the screw 225 to rotate, the screw 225 drives the turbine 228 to rotate, and the turbine 228 drives the light-emitting unit 222 to rotate, so as to control the rotation angle of the light-emitting unit 222, enabling it to adjust different irradiation angles and achieve different lighting effects. At the same time, by setting the avoidance notch 213, when the light-emitting lamp body moves, it can prevent the transmission cylinder 211 from interfering with the cooperation between the screw 225 and the turbine 228, and while protecting with the protective glass, the light emitted by the light-emitting unit 222 can be emitted.

[0045] As Figure 5 and Figure 8 shown, in some embodiments of the wall washer lamp described in this embodiment, the light-emitting unit 222 includes a light-emitting source 2221 and a light filter belt 2222 movably wound around the light-emitting source 2221. Both ends of the light-emitting source 2221 are rotatably connected to the second lamp housing 227, and a cleaning brush 2223 is sleeved on the light filter belt 2222.

[0046] In actual application, when the light-emitting source 2221 rotates, it drives the light filter belt 2222 to rotate synchronously. At this time, the cleaning brush 2223 slides along the surface of the light-emitting source 2221 under its own weight, so as to clean the surface of the light-emitting source 2221, and at the same time drives the light filter belt 2222 to slide relative to the light-emitting source 2221 for switching, thereby changing the light color. The sundries generated by cleaning can be discharged from the second air chamber 221 along with the air flow, extending the service life of the wall washer lamp.

[0047] As Figure 7 shown, in some embodiments of the wall washer lamp described in this embodiment, the accommodating groove 212 further protrudes with a guiding column 214 penetrating through the fixing plate 24. The second lamp housing 227 is slidably sleeved on the outer wall of the guiding column 214, so as to guide and limit the light-emitting lamp body, making the reciprocating sliding of the light-emitting lamp body more stable.

[0048] As Figures 4 to 6 shown, in some embodiments of the wall washer light described in this embodiment, an insulating buffer pad 26 is provided on one side of the fixing plate 24 facing the second lamp housing 227 to prevent the light-emitting lamp body from colliding with the fixing plate 24 when sliding, causing damage and abnormal noise.

[0049] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made to the structure, features, and principles described in the scope of the present invention patent application are included in the protection scope of the present invention patent application.
