[0028] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0029] The embodiment of the present application discloses a projection lamp 100 .

[0030] Reference Figure 1-Figure 3According to the embodiment of the present application, the projection lamp 100 comprises: a housing 1 and a dimming mechanism 2. The housing 1 is suitable for being installed on a mounting wall, and the housing 1 defines an installation space 11. The installation space 11 forms a projection hole 12 on the end wall of the housing 1. Specifically, along the height direction of the housing 1, the projection hole 12 is located on the lower end wall of the housing 1. A light emitting member 13 is provided in the housing 1 opposite to the projection hole 12. The height direction of the housing 1 can refer to Figure 2 The up and down directions in .

[0031] In some specific embodiments, the light-emitting element 13 may be an LED (Light-emitting Diode) lamp or the like.

[0032] In some specific embodiments, the installation wall may be a ceiling or the like.

[0033] The dimming mechanism 2 is arranged in the housing 1 and is located on a side of the light-emitting member 13 close to the projection hole 12, that is, the dimming mechanism 2 is located below the light-emitting member 13, and the dimming mechanism 2 includes a transmission assembly 21 and a plurality of blades 22, and the plurality of blades 22 are arranged in sequence along the circumferential direction of the housing 1, and the side walls of any two adjacent blades 22 are abutted. Specifically, along the first direction of the housing 1, the front end wall of the blade 22 abuts against the rear end wall of the adjacent blade 22 located in front of the blade 22, and the rear end wall of the blade 22 abuts against the front end wall of the adjacent blade 22 located behind the blade 22. The first direction of the housing 1 can refer to Figure 3 The front-to-back direction.

[0034] Furthermore, along the radial direction of the shell 1, a dimming gap 221 is jointly defined between the areas where the multiple blades 22 are close to the center line of the shell 1, that is, the dimming gap 221 is located in the central area of ​​the shell 1, and the dimming gap 221 is opposite to both the light-emitting component 13 and the projection hole 12, the light emitted by the light-emitting component 13 passes through the dimming gap 221 and the projection hole 12 in turn and is projected onto the illumination area, and the blades 22 are suitable for shielding the light emitted by the light-emitting component 13.

[0035] It should be noted that the midline of the housing 1 is the center line of the housing 1 .

[0036] The transmission assembly 21 is in transmission connection with the plurality of blades 22. When the transmission assembly 21 is driven, the plurality of blades 22 are driven to move closer to or away from the center line of the housing 1 to adjust the size of the dimming gap 221. Specifically, when the transmission assembly 21 drives the plurality of blades 22 to move away from the center line of the housing 1, the dimming gap 221 increases, and the amount of light emitted by the light-emitting element 13 blocked by the blades 22 decreases, thereby achieving a technical effect of increasing the illumination range of the light-emitting element 13. When the transmission assembly 21 drives the plurality of blades 22 to move closer to the center line of the housing 1, the dimming gap 221 decreases, and the amount of light emitted by the light-emitting element 13 blocked by the blades 22 increases, thereby achieving a technical effect of reducing the illumination range of the light-emitting element 13.

[0037] It should be noted that when the dimming gap 221 is at its maximum size, the plurality of blades 22 do not block the light of the light emitting element 13, and the lighting range of the light emitting element 13 is the maximum lighting range. When the dimming gap 221 is at its minimum size, the light emitted by the light emitting element 13 is completely blocked by the plurality of blades 22, and the lighting range of the light emitting element 13 is the minimum lighting range, that is, when the dimming gap 221 is at its minimum size, the projection lamp 100 cannot project light to the lighting area.

[0038] Thus, the light emitted by the light emitting element 13 sequentially passes through the dimming gap 221 and the projection hole 12 and is projected to the lighting area, and the transmission assembly 21 drives the plurality of blades 22 to move closer to or away from the center line of the housing 1 to reduce or increase the size of the dimming gap 221, and the blades 22 are suitable for shielding the light emitted by the light emitting element 13, so that the lighting range of the projection lamp 100 can be adjusted. Compared with the prior art, the user does not need to replace the shade with different diameters to adjust the lighting range of the projection lamp 100, thereby reducing the difficulty of adjusting the lighting range of the projection lamp 100, and further improving the user experience of the projection lamp 100.

[0043] In some specific embodiments, when the first driving member 14 drives the transmission member 211 to rotate clockwise around the central axis of the transmission member 211, the transmission member 211 drives the multiple blades 22 to move away from the center of the housing 1 along the corresponding guide rails 2122, thereby achieving the technical effect of increasing the dimming gap 221.

[0054] In some specific embodiments, the second driving member 163 may be a motor or the like.

[0055] Reference Figure 1 , Figure 2 and Figure 8 In some embodiments of the present application, the pivot portion 162 includes a first pivot ring 1621 and a second pivot ring 1622. Along the height direction of the shell 1, the first pivot ring is located above the second pivot ring 1622. The first pivot ring 1621 and the second pivot ring 1622 are spaced apart and connected to each other. An accommodating gap 1623 is defined between the first pivot ring 1621 and the second pivot ring 1622. The second driving gear 1631 and the second gear ring 1611 are both located in the accommodating gap 1623. The second driving gear 1631 is limitedly matched with the first pivot ring 1621 and the second pivot ring 1622.

[0056] By limiting the cooperation between the second driving gear 1631, the first pivot ring 1621 and the second pivot ring 1622, it is possible to prevent the second driving gear 1631 from deviating from the preset installation position, prevent the second driving gear 1631 from being unable to engage with the second gear ring 1611, and prevent the second driving gear 1631 from being unable to drive the upper shell 15 to rotate around the central axis of the upper shell 15, thereby improving the working reliability of the projection lamp 100.

[0057] In some specific embodiments, the first pivot ring 1621 and the second pivot ring 1622 may be connected and matched with each other by screws.

[0058] Reference Figure 8 In some embodiments of the present application, the projection lamp 100 may further include: a swing mechanism 3, the swing mechanism 3 is arranged in the upper shell 15, the swing mechanism 3 includes a third driving member 31, a transmission belt 32 and a driving wheel 33, the third driving member 31 is connected and cooperated with the upper shell 15, the driving wheel 33 is pivotally connected to the upper shell 15, an output end of the third driving member 31 is provided with an output wheel 311, the transmission belt 32 is transmission-connected between the driving wheel 33 and the output wheel 311, the pivot portion 162 is provided with a pivot arm 1624 near the end wall of the upper shell 15, the pivot arm 1624 is sleeved on the outer peripheral wall of the driving wheel 33 and is connected and cooperated with the driving wheel 33, when the third driving member 31 drives the transmission belt 32 to rotate, the third driving member 31 drives the upper shell 15 to rotate relative to the lower shell 16.

[0059] Specifically, the fixing portion 161 is fixedly connected to the mounting wall, and the pivoting portion 162 is connected to the driving wheel 33 via the pivot arm 1624. That is to say, the relative position between the driving wheel 33 and the mounting wall remains unchanged, and the third driving member 31 drives the output wheel 311 to rotate around the central axis of the third driving member 31, and the output wheel 311 drives the transmission belt 32 to rotate between the output wheel 311 and the driving wheel 33, and the transmission belt 32 drives the driving wheel 33 to rotate around the pivot axis between the driving wheel 33 and the upper shell 15. Since the driving wheel 33 and the lower shell 16 both maintain an unchanged relative position with the mounting wall, when the driving wheel 33 rotates around the pivot axis between the driving wheel 33 and the upper shell 15, the third driving member 31 drives the upper shell 15 to rotate relative to the lower shell 16, thereby achieving the technical effect of adjusting the lighting direction of the light-emitting member 13.

[0060] In some specific embodiments, the third driving member 31 may be a motor or the like.

[0061] Reference Figure 8 In some embodiments of the present application, a limiting groove 331 is provided on the outer wall of the driving wheel 33, and a connecting member 332 is provided in the limiting groove 331.

[0062] Specifically, by the limiting cooperation between the connecting member 332 and the limiting groove 331, and by the fixed connection between the connecting member 332 and the pivot arm 1624, the technical effect of fixedly connecting the pivot part 162 and the upper shell 15 can be achieved, and the connecting member 332 can be prevented from being separated from the limiting groove 331, and the connecting member 332 can be prevented from being unable to be fixedly connected to the pivot arm 1624, and the pivot part 162 can be prevented from being unable to maintain a relative position unchanged with the driving wheel 33, thereby improving the working reliability of the projection lamp 100.

The driving rod 173 is threadedly connected to the transmission hole 1711, and the driving rod 173 is used to drive the clamping member 171 to move close to or away from the side wall of the connecting groove 17 to adjust the size of the clamping gap 172, which is suitable for fixing the shell 1 and the installation wall through the clamping member 171.

[0064] Specifically, the mounting wall is provided with a connecting structure, and the clamping member 171 clamps the connecting structure in the connecting groove 17 to fix the connecting shell 1 and the mounting wall. First, the driving rod 173 is turned to drive the clamping member 171 to move away from the upper end wall of the connecting groove 17 to increase the clamping gap 172, and then the connecting structure extends into the clamping gap 172. Finally, the driving rod 173 is turned to drive the clamping member 171 to move close to the upper end wall of the connecting groove 17 to reduce the clamping gap 172 and clamp the connecting structure in the connecting groove 17, thereby achieving the technical effect of fixing the connecting shell 1 and the mounting wall.

[0065] In addition, different installation walls usually have connecting structures of different sizes. The driving rod 173 drives the clamping member 171 to move to adjust the size of the clamping gap 172. The clamping gap 172 can match the connecting structures of different sizes, so that the shell 1 can be installed on different installation walls, thereby improving the user experience of the projection lamp 100.

[0066] Reference Figure 2 and Figure 8In some embodiments of the present application, an anti-glare cup 18 is provided in the shell 1. The anti-glare cup 18 is located on the side of the dimming mechanism 2 close to the bottom wall of the shell 1.
