As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0030] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] Combination Figures 1 to 3 As shown, an embodiment of the present invention provides a wall washer lamp, including a lamp body assembly 10, an optical assembly 20, a driving assembly 30 and a reflecting assembly 40. The lamp body assembly 10 includes a control module 11, an optical sensing module 12 and a lamp body 13. The control module 11 and the optical sensing module 12 are both arranged on the lamp body 13. The driving assembly 30 includes a first driving assembly 31 and a second driving assembly 32 both arranged on the lamp body 13. The first driving assembly 31 is connected to the reflecting assembly 40 and can drive the reflecting assembly 40 to rotate. The second driving assembly 32 is connected to the optical assembly 20 and can drive the optical assembly 20 to rotate. The light emitted by the optical assembly 20 is reflected by the reflecting assembly 40 to fill in the light for the designated area.

[0032] In this embodiment, the lamp body assembly 10 includes a control module 11, an optical sensing module 12 and a lamp body 13, and the control module 11 and the optical sensing module 12 are both arranged on the lamp body 13. The control module 11 is used to control various functions of the wall washer lamp, and the optical sensing module 12 is used to monitor the ambient light intensity in real time, thereby providing a basis for the control module 11 to adjust the luminous flux. The driving assembly 30 is composed of a first driving assembly 31 and a second driving assembly 32, both of which are installed on the lamp body 13. The first driving assembly 31 is connected to the reflection assembly 40, and can drive the reflection assembly 40 to rotate to change the reflection angle of the light, so as to realize the fill light function for the target area; the second driving assembly 32 is connected to the optical assembly 20, and can drive the optical assembly 20 to rotate, so as to adjust the irradiation direction of the light according to the lighting requirements. During the working process, the light emitted by the optical assembly 20 can be reflected by the reflection assembly 40 to fill the light for the designated area, thereby achieving the effect of improving the uniformity of the irradiation.

[0033] In one embodiment, the first driving component 31 includes a first driving member 311 and a deforming wheel 312. The first driving member 311 is arranged on the lamp body 13. The deforming wheel 312 is connected to the output end of the first driving member 311. A deforming groove 3121 is arranged on the deforming wheel 312. The reflective component 40 is connected in the deforming groove 3121.

[0034] In this embodiment, the first driving member 311 (such as a stepping motor) is fixed on the lamp body 13, and is used to drive the deformation wheel 312 to rotate. The deformation wheel 312 is connected to the output end of the first driving member 311, and is provided with a deformation groove 3121 on its surface. The deformation groove 3121 is a groove structure of a specific shape (such as an irregular annular groove), which is used to accommodate the installation part of the reflection component 40. The reflection component 40 is connected to the deformation wheel 312 by being inserted into the deformation groove 3121, so that the reflection component 40 is synchronously adjusted with the rotation of the deformation wheel 312. By designing the shape and position of the deformation groove 3121, the curvature of the reflection component 40 can be effectively controlled to achieve the adjustment of the reflection curvature. It should be noted that the concepts of "angle" and "radian" corresponding to the reflective component 40 mentioned in the present invention are different. The angle of the reflective component 40 refers to the reflection angle generated by the sliding of the reflective component 40 relative to the optical component 20, and the radian of the reflective component 40 refers to the reflection radian generated by the rotation of the reflective component 40 itself, that is, when the reflective component 40 slides, the position will change, and when the reflective component 40 rotates, the position will not change, and only the radian itself will be fine-tuned. When the first driving member 311 is started, it drives the deformation wheel 312 to rotate, so that the reflection radian of the reflective component 40 is adjusted accordingly, thereby adjusting the reflection radian of the light so as to fill in the designated area.

[0035] In one embodiment, two first driving components 31 are provided and are respectively disposed at two ends of the lamp body 13 , and two ends of the reflection component 40 are respectively connected to the two deformation grooves 3121 .

[0036] In this embodiment, the first drive assembly 31 can be designed to be two, respectively arranged at the two ends of the lamp body 13, so as to more stably control the curvature adjustment of the reflective assembly 40. Each first drive assembly 31 includes a first drive member 311 and a corresponding deformation wheel 312. Each deformation wheel 312 is provided with a deformation groove 3121, and the two ends of the reflective assembly 40 are respectively inserted into the two deformation grooves 3121, thereby realizing double-end control of the reflective assembly 40. The two first drive assemblies 31 can work synchronously. When the first drive member 311 is started, the deformation wheels 312 at both ends are driven respectively by the output end of the first drive member 311, so that the curvature of the two ends of the reflective assembly 40 changes. This double-end drive design improves the stability of the reflective assembly 40, avoids the imbalance or tilt phenomenon that may be caused by single-end drive, and ensures that the reflective assembly 40 remains stable during rotation.

[0037] Furthermore, by controlling the rotation of the two end deformation wheels 312, the curvature of the reflective assembly 40 can be fine-tuned to achieve the desired illumination effect. Since both ends of the reflective assembly 40 are inserted into the deformation slots 3121, the rotation of the two deformation wheels 312 will synchronously change the overall curvature of the reflective assembly 40 to achieve a more uniform light distribution.

[0038] In one embodiment, the reflective assembly 40 includes a reflective sheet 41 and a reflective control member 42, the end of the reflective sheet 41 is connected to the deformation groove 3121, the reflective control member 42 is arranged on the lamp body 13, and a sliding member 411 is arranged on the reflective sheet 41, and the sliding member 411 is slidably connected to the reflective control member 42.

[0039] In this embodiment, the end of the reflector 41 is connected to the deformation groove 3121 to ensure that it is adjusted synchronously with the deformation wheel 312 to achieve curvature adjustment. The reflection control member 42 is fixed on the lamp body 13 to assist in controlling the rotation position of the reflector 41. A sliding member 411 is provided on the reflector 41, and the sliding member 411 is installed on the reflection control member 42 in a sliding connection. The sliding member 411 can move along the guide track of the reflection control member 42, so that the reflector 41 can achieve angle adjustment within a specific range. The angle control of the reflector 41 is achieved by changing the position of the sliding member 411, that is, when the sliding member 411 moves along the reflection control member 42, the angle of the reflector 41 will change accordingly, thereby affecting the reflection direction of the light.

[0040] In actual operation, the first driving assembly 31 drives the deformation wheel 312 to rotate, and one end of the reflective sheet 41 synchronously follows the deformation wheel 312 to adjust the curvature through the connection point fixed in the deformation groove 3121. At the same time, the sliding member 411 moves in the guide track of the reflection control member 42, providing support and guidance for the moving position of the reflective sheet 41, so that the reflective sheet 41 can adjust its reflection angle more smoothly.

[0041] In one embodiment, the reflective assembly 40 further includes a reflective driving member 43 , which is connected to the sliding member 411 . The reflective sheet 41 is a flexible reflective sheet. The reflective driving member 43 can drive the sliding member 411 to rotate, thereby driving the flexible reflective sheet to rotate.

[0042] In this embodiment, the reflector 41 is a flexible reflector, which can improve the problem of uneven illumination. The reflector 41 adopts the total reflection principle, and the reflectivity is 98%. Its flexible characteristics can change the curvature of the reflective surface through the deformation groove 3121 of the deformation wheel 312 to achieve the fill light effect of the specified area. The reflector 41 can produce appropriate bending when an external force is applied, so as to adjust its reflection curvature. The reflective drive 43 (such as a stepping motor) is connected to the sliding member 411, and can drive the sliding member 411 to rotate itself to achieve the angle adjustment of the reflector 41.

[0043] In the specific operation process, the reflective driving member 43 applies a driving force to rotate the sliding member 411 around its axis, and the rotation of the sliding member 411 drives the reflective sheet 41 to rotate accordingly. Since the reflective sheet 41 has a flexible characteristic, it can cooperate with the deformation wheel 312 to flexibly adjust the curvature of its reflective surface during the rotation process, so that the curvature of the reflected light is more accurate, thereby achieving a fill light effect for a specified area, so that the wall washer can achieve more accurate light control in complex lighting scenes.

[0044] Combination Figures 4 to 8 As shown, in one embodiment, the sliding member 411 includes a sliding body 4111, a fixed groove 4112 arranged at the front end of the sliding body 4111 and a slider 4113 arranged at the rear end of the sliding body 4111, an arc-shaped sliding groove 421 parallel to the deformation groove 3121 is arranged on the reflection control member 42, the slider 4113 is slidably arranged in the arc-shaped sliding groove 421, the reflection sheet 41 is fixed in the fixed groove 4112, and the reflection driving member 43 is connected to the sliding body 4111.

[0045] In this embodiment, the fixed groove 4112 is located at the front end of the sliding body 4111, and is a groove structure of a specific shape (usually adapted to the reflective sheet 41, and in this embodiment, the fixed groove 4112 is configured to clamp the reflective sheet 41), which is used to receive and fix one end of the reflective sheet 41. By inserting the end of the reflective sheet 41 into the fixed groove 4112, the sliding member 411 can drive the reflective sheet 41 to make corresponding angle adjustments when moving. The slider 4113 is located at the rear end of the sliding body 4111, and is slidably mounted in the arcuate groove 421 on the reflection control member 42. The arcuate groove 421 is an arcuate track structure parallel to the deformation groove 3121, which provides a movement path for the slider 4113. The sliding of the slider 4113 along the arcuate groove 421 allows the sliding body 4111 to move smoothly along a predetermined arcuate track. In addition, the reflection driving member 43 is connected to the sliding body 4111, and can apply a driving force to the sliding body 4111. As shown in FIG. Figure 7 As shown, at this time, the reflective assembly 40 is in the initial state. After the reflective assembly 40 is started, the reflective assembly 40 slides downward to Figure 8 Status shown. Figure 8 The arrow in the figure indicates the direction of the fill light emitted by the optical component 20 and reflected by the reflective component 40.

[0046] In one embodiment, the optical assembly 20 includes a heat sink 21 , a light board 22 , and a lens 23 which are sequentially arranged.

[0047] In this embodiment, the radiator 21 is mounted on the lamp body 13 to effectively dissipate the heat generated by the lamp board 22 during operation. The radiator 21 can be made of a high thermal conductivity material, and the surface area is increased by a special heat dissipation fin design so as to quickly conduct and dissipate the heat to the surrounding environment, thereby avoiding overheating of the lamp board 22, extending the service life of the light source, and ensuring the stability of the wall washer lamp under long-term use. The lamp board 22 is closely attached to the radiator 21 to provide a light source. A plurality of LED lamp beads are mounted on the lamp board 22, and these LED lamp beads are arranged according to specific lighting requirements to provide uniform light output. The lens 23 is the outermost structure of the optical component 20, which is mounted in front of the lamp board 22 and is used to converge, shape or diverge the light emitted by the lamp board 22. The lens 23 is made of a high transparency material and has a polarized total reflection and refraction design, which can emit the light of the lamp board 22 according to a preset angle and shape. The shape and surface of the lens 23 are optically designed so that it can control the light within a specific angle range according to application requirements to meet different lighting scene requirements.

[0048] Combination Fig. 9 As shown, the embodiment of the present invention further provides a method for adjusting uniform illumination of the wall washer lamp as described above, comprising the following steps S901-S904:

[0049] S901, the control module 11 initializes the wall washing height value and the lamp installation distance value according to the wall washing mode set by the user;

[0050] S902, the control module 11 calculates the output luminous flux using the ambient light data collected by the optical sensing module 12, and outputs corresponding current data to the optical component 20 according to the output luminous flux, so that the optical component 20 illuminates the target wall surface;

[0051] S903, the control module 11 drives the second driving component 32 using the wall washing height value and the lamp installation distance value to rotate the optical component 20 to a preset angle position;

[0052] S904, the control module 11 obtains the illumination values ​​of different positions of the target wall collected by the optical sensing module 12, obtains the uniformity of the illumination values ​​according to the illumination values ​​at different positions, and drives the first driving component 31 to adjust the placement angle of the reflection component 40 so that the uniformity is equal to or greater than the first set threshold.

[0053] In this embodiment, the control module 11 first initializes the wall washing height and the installation distance of the wall washer lamp according to the wall washing mode set by the user. The user can select different wall washing modes to meet different lighting needs. The system will automatically set the corresponding wall washing height value and the installation distance value between the lamp and the wall according to the selected wall washing mode. The wall washer lamp in this embodiment has three wall washing modes to choose from: high-brightness commercial wall washing mode (strongly highlighting the illuminated wall scene), commercial wall washing mode (normally highlighting the illuminated wall scene), and household wall washing mode (highlighting the illuminated wall scene while taking into account the comfort of the human eye). The range of the wall washing height value usually selected can be 3 meters to 10 meters, and the range of the installation distance value from the wall washer lamp to the wall can be 0.2 meters to 0.5 meters. After initializing these parameters, the system can use these data to control light and adjust the uniformity of illumination in the next steps.

[0054] After the initialization is completed, the control module 11 obtains the current ambient light data through the optical sensing module 12. The optical sensing module 12 monitors the light intensity of the environment in real time and transmits the collected data to the control module 11. The control module 11 calculates the required output luminous flux according to the preset algorithm, combined with the ambient light data and the initialization parameters (i.e., the wall washing height value and the installation distance value). The output luminous flux is usually the internal setting data obtained through experiments, such as 1000LM (lumens) for 3 meters and 3000LM (lumens) for 10 meters, etc. Different wall washing height values ​​correspond to different output luminous fluxes. Then, the control module 11 outputs the corresponding current data to the optical component 20 according to the output luminous flux to adjust the light output intensity of the optical component 20, so that the light is irradiated onto the target wall surface to meet the lighting requirements of the current environment. The corresponding current can also be adjusted according to the formula of the output luminous flux and the working power of the wall washing lamp, and the output luminous flux = the light efficiency value of the wall washing lamp × the power of the wall washing lamp × (1+X%) light efficiency coefficient, and X can be 3-5. The smaller the power of the lamp beads in the same wall washer, the higher the light efficiency value, which can be calculated by the control module 11 to output the corresponding current data to the optical component 20. The wall washer of this embodiment adopts an LED wall washer. LED is a light emitting diode. If the current is too small or the forward voltage is insufficient, the LED cannot work normally. Therefore, the minimum current data issued by the control module 11 needs to be within the standard range of the LED.

[0055] After the control module 11 calculates and sets the output light intensity of the optical component 20, it will use the wall washing height value and the lamp installation distance value to calculate the output forward and reverse step number signal, and control the second drive component 32 to drive the optical component 20 to rotate to a preset angle position according to the output forward and reverse step number signal. The second drive component 32 adjusts the angle of the optical component 20 according to these parameters so that the light is projected onto the target wall at an appropriate angle. Through this adjustment, the coverage of the light is optimized to ensure that the target wall is evenly illuminated at different installation distances and heights. It should be noted that the output luminous flux is different for different wall washing height values. The higher the wall washing height, the greater the corresponding output luminous flux. The lamp installation distance value affects the lamp illumination angle, which can be obtained through experiments. For example, if the lamp installation distance value is 0.3 meters, the illumination angle is 15 degrees; if the lamp installation distance value is 0.5 meters, the illumination angle is 12 degrees. The illumination angle refers to the angle between the optical component 20 and the horizontal installation surface.

[0056] After completing the angle adjustment of the optical component 20, the control module 11 obtains the illumination values ​​at different positions on the target wall again through the optical sensing module 12. The optical sensing module 12 collects illumination at multiple points on the target wall and transmits the data to the control module 11. The control module 11 calculates the uniformity of the illumination value based on the collected illumination values ​​at different positions. If it is detected that the uniformity of the current wall is lower than the first set threshold (for example, 90%), the control module 11 will start the first drive component 31 and drive the reflection component 40 to adjust its placement angle to achieve uniform distribution of light on the wall. The first drive component 31 controls the angle of the reflection component 40 so that the light can compensate for the low-illuminance area on the wall and gradually improve the uniformity until the set threshold is met or higher.

[0057] In one embodiment, the method for adjusting uniform illumination of a wall washer lamp further includes:

[0058] The control module 11 acquires the illumination value collected by the optical sensing module 12 in real time and calculates the corresponding illumination change value;

[0059] The control module 11 determines whether the illumination change value is less than a second set threshold value; if so, it returns to continue collecting; if not, it returns to re-adjust and calculate the output luminous flux.

[0060] In this embodiment, the control module 11 obtains the ambient light data in real time through the optical sensing module 12. The optical sensing module 12 continuously monitors and collects the illuminance value on the target wall, and transmits the data to the control module 11. The control module 11 calculates the change of the current ambient light intensity according to the received illuminance value, and generates an illuminance change value to reflect the fluctuation degree of the current ambient light illuminance. The control module 11 compares the calculated illuminance change value with the preset second set threshold value to determine whether the change of the ambient light illuminance exceeds the allowable range of the system. The second set threshold value can be set according to the needs of the specific application scenario, for example, it can be set to 10% to ensure that the system will only trigger subsequent adjustment operations when the ambient light changes significantly, thereby avoiding the impact of frequent adjustments on the stability of the system. If the control module 11 determines that the illuminance change value is within the second set threshold value, it is considered that the ambient light illuminance change is small and will not affect the current lighting effect. At this time, the system will return to continue to collect ambient light data and maintain the current working mode to ensure that the wall washer lamp maintains stability and consistency in small ambient light changes. If the control module 11 determines that the illumination change value exceeds the second set threshold, it means that the ambient light has changed significantly, which may affect the illumination uniformity and lighting effect of the target wall. At this time, the control module 11 will enter the readjustment process and recalculate the output luminous flux to adapt to the new ambient light conditions. The control module 11 will calculate the appropriate output luminous flux again based on parameters such as the current wall washing mode, the initialized wall washing height value, and the lamp installation distance value to ensure that the light intensity output by the optical component 20 matches the new ambient light level. Through this real-time monitoring and dynamic adjustment mechanism, the system can automatically readjust the output luminous flux of the wall washer when the ambient light changes significantly, ensuring the uniformity of the wall illumination and the stability of the lighting effect. This method further improves the intelligent control level of the wall washer, so that it can not only adapt to the lighting needs in different scenarios, but also automatically respond when the ambient light conditions change, and continue to provide stable and high-quality lighting effects.

[0061] In one embodiment, the method for adjusting uniform illumination of a wall washer lamp further includes:

[0062] When the power is off, the control module 11 records the wall washing mode set by the user, the angle position of the optical component 20, and the placement angle of the reflective component 40, so as to continue to operate according to the recorded data when the power is on.

[0063] In this embodiment, the uniform illumination adjustment method of the wall washer lamp further includes a power-off memory function to ensure that after power failure, the wall washer lamp can automatically restore to the working state previously set by the user when power is restored, avoiding repeated settings, and improving the convenience of use and user experience. Specifically, when the system detects a power failure, the control module 11 will automatically perform a data saving operation to record the key parameters and current status set by the user, including: recording the wall washing mode selected by the user to ensure that after power is restored, the system can directly enter the user-specified working mode without resetting. The angle of the optical component 20 determines the direction and range of light irradiation, and the control module 11 will record the current angle position of the optical component 20. Save after power failure so that the angle of the optical component 20 can be restored after power is turned on, ensuring that the irradiation direction and range of the light before and after power failure remain consistent. The placement angle of the reflective component 40 directly affects the reflection path and irradiation uniformity of the light. The control module 11 records the angle setting of the current reflective component 40 so that after power is restored, the reflective component 40 can maintain the previous angle to ensure that the uniformity of the wall illumination is not affected by power failure. When the power is turned on, the control module 11 will first read the previously saved parameters and states, and quickly restore the working state of the wall washer based on the recorded data, so that the system continues to operate according to the settings before the power outage. The user does not need to manually reset after each power outage, which effectively improves the convenience of the system and saves operation time.
