Description

Technical Field

[0001] The present application relates to the field of lighting fixtures, and in particular to a wall washer lamp with adjustable light-emitting angle. Background Art

[0002] Wall washer lights are a type of lighting used for architectural decorative lighting. They are widely used in government lighting projects, commercial venues, subways, elevated overpasses, building exterior walls, architectural landmarks and other interior and exterior wall panoramic floodlighting.

[0003] Traditional wall washers emit direct light, with the light emitting vertically from the lamp body. However, when the wall washers are set on an inclined table, the heights of the two ends of the wall washers are different, and there are places on the wall on the inclined table that the wall washers cannot illuminate, resulting in inconsistent lighting effects. Summary of the Invention

[0004] In order to solve the problem of uneven lighting effects of wall washers on tilted countertops, the present application provides a wall washer with adjustable lighting angle.

[0005] The present application provides a wall washer lamp with adjustable light emission angle, which adopts the following technical solution:

[0006] A wall washer lamp with adjustable light-emitting angle includes a lamp body, wherein a plurality of substrates for conducting electricity are provided in the lamp body, and flexible wires are used to conduct electricity between two adjacent substrates. A lamp bead is electrically connected to each substrate, and a lens for focusing light is provided on the substrate. The substrate and the lamp body are rotatably arranged via a rotating shaft, and the plurality of substrates rotate along the length direction of the lamp body. A driving assembly is provided on the lamp body for driving the substrates to rotate along the length direction of the lamp body, and each rotating shaft is connected to the driving assembly via a connecting assembly.

[0007] By adopting the above technical solution, when the lamp body is installed on the inclined table, the substrate is first energized, and the substrates are electrically conductive through wires. The lamp beads on the substrates light up, and the lens emits light vertically out of the lamp body. Then the driving component is turned on, and the driving component drives several substrates to rotate around the rotating axis along the length direction of the lamp body through the connecting component, thereby realizing the adjustment of the deflection angle of the light emitted from the lamp body, so that the light can be irradiated vertically onto the wall, thereby achieving a unified wall washing lamp effect.

[0008] In a specific possible implementation scheme, the driving assembly includes a linear motor provided on the lamp body, and a driving bar is provided on the output shaft of the linear motor;

[0009] The connecting assembly includes a connecting rod sleeved on the rotating shaft, the connecting rod is used to drive the rotating shaft to rotate, a plurality of driving blocks are rotatably provided on the driving bar, the driving blocks correspond one-to-one to the connecting rod, and a driving groove is provided on the connecting rod for the driving blocks to slide, and the driving blocks slide along the driving groove so that the connecting rod drives the rotating shaft to rotate.

[0010] By adopting the above technical solution, when adjusting the deflection angle of the light, the linear motor is turned on first. The output shaft of the linear motor drives the driving block to rotate and slide along the driving groove through the driving bar. The driving block rotates while driving the connecting rod to rotate. The connecting rod drives the base plate to rotate through the rotating shaft, so that the deflection angle of the lamp beads and lenses on the base plate changes, thereby realizing the adjustment of the deflection angle of the light emitted from the lamp body.

[0011] In a specific possible implementation scheme, the connecting rod is provided with a rotating groove, and the connecting rod is provided with a rotating block 1 and a rotating block 2 for sliding in the rotating groove, and the rotating shaft is provided with a push block for sliding in the rotating groove, and the push block is located between the rotating block 1 and the rotating block 2, and the rotating block 1 and the rotating block 2 are both driven to slide by a tightening spring, and the lamp body is provided with an adjustment component for driving the push block to push the rotating block 1 or the rotating block 2 to slide.

[0012] By adopting the above technical solution, when the connecting rod rotates, the rotating block 1 and the rotating block 2 clamp the push block through the pressing spring, so that the push block moves together with the rotating block 1 and the rotating block 2, so the connecting rod drives the rotating shaft to rotate in advance; when the inclination angle adjustment of several substrates is completed, the push block is driven by the adjustment component to push the rotating block 1 or the rotating block 2 to rotate, so that the deflection angle of the substrate changes, thereby realizing the adjustment of the deflection angle of a single light.

[0013] In a specific possible implementation scheme, the adjustment assembly includes an adjustment rod rotatably arranged on the lamp body, the adjustment rod is provided with a control member for driving the rotation shaft to rotate, and the adjustment rod is provided with an elastic sheet for contacting the lamp body.

[0014] By adopting the above technical solution, when adjusting the deflection angle of a single substrate, the adjustment rod is first rotated, and the adjustment rod drives the rotating shaft to rotate through the control member, so that the deflection angle of the substrate changes. After the adjustment is completed, the adjustment rod is pressed against the lamp body through the elastic sheet, thereby realizing the restriction of the adjustment rod and improving the stability of the substrate after adjustment.

[0015] In a specific embodiment, the axis of the adjusting rod is collinear with the axis of the rotating shaft;

[0016] The control component includes a push plate and a permanent magnet arranged on the end surface of the adjusting rod. The push plate is arranged along the radial direction of the adjusting rod. A rotating sleeve is fixedly sleeved on the rotating shaft. A connecting rod is slidingly provided in the rotating sleeve. An adsorption block for the permanent magnet to adsorb is provided on the connecting rod. The push plate is used to push the adsorption block to rotate.

[0017] By adopting the above technical solution, when the adjusting rod rotates clockwise, the permanent magnet 1 of the adjusting rod rotates to a place of the adsorption block, and adsorbs the adsorption block 1 from the rotating sleeve to the adjusting rod, and then the adjusting rod is rotated, the push plate pushes the adsorption block 1 to rotate, the adsorption block 1 drives the rotating sleeve to rotate through the connecting rod, and the rotating sleeve drives the rotating shaft to rotate, thereby realizing the adjustment of the clockwise deflection angle of a single substrate.

[0018] In a specific possible implementation scheme, a second permanent magnet for adsorbing the first adsorption block is provided on the end surface of the adjusting rod, and the push plate is located between the first permanent magnet and the second permanent magnet.

[0019] With this technical solution, when the adjustment rod rotates counterclockwise, permanent magnet 2 attracts adsorption block 1 to the end face of the adjustment rod, which then rotates via the push plate. Adsorption block 1 then drives the rotating shaft counterclockwise via the linkage rod and rotating sleeve, thereby adjusting the counterclockwise light deflection angle.

[0020] In a specific feasible implementation scheme, an electromagnet is provided on the rotating sleeve, and an adsorption block 2 for the electromagnet to adsorb is provided on the connecting rod. The electromagnet adsorbs the adsorption block 2 so that the adsorption block 1 is separated from the push plate, and the electromagnet and the linear motor have the same power on and off state.

[0021] By adopting the above technical solution, when the linear motor drives the substrate to adjust the deflection angle, the electromagnet is energized and adsorbs the adsorption block 2, and the adsorption block 2 drives the adsorption block 1 to slide in the direction away from the adjustment rod through the connecting rod. The adsorption block 1 is disengaged from the push plate, permanent magnet 1 or permanent magnet 2, so that the adjustment rod does not rotate with the rotation of the rotating shaft. When the linear motor stops, the electromagnet is de-energized, and the permanent magnet 1 or permanent magnet 2 adsorbs the adsorption block 1 to the adjustment rod, so that the adjustment rod can drive the rotating shaft to rotate, thereby improving the flexibility of the adjustment rod to adjust the rotating shaft.

[0022] In a specific possible implementation scheme, a light-shielding tube is provided on the substrate, the lamp beads and the lens are both located in the light-shielding tube, and a light outlet is provided on the light-shielding tube.

[0023] By adopting the above technical solution, the scattered light emitted by the lamp beads is shielded by the light-shielding tube, which effectively prevents the scattered light of the lamp beads from affecting the brightness of the straight light emitted by the lens.

[0024] In a specific feasible implementation scheme, a transparent plate is provided on the lamp body, and the transparent plate is arranged along the length direction of the lamp body. A shading plate is provided on the lamp body, and sealing heads are provided on both ends of the lamp body. A waterproof pad is provided between the sealing head and the lamp body.

[0025] By adopting the above technical solution, the transparent plate can not only achieve light penetration, but also effectively prevent water from entering the interior of the lamp body. The light on the side of the lamp body away from the wall is blocked by the shading plate, so that the viewer feels that the light on the wall is brighter, which improves the viewer's viewing comfort. The two ends of the lamp body are sealed by the sealing head on the lamp body, and the space between the sealing head and the lamp body is waterproofed by the waterproof pad.

[0026] In a specific possible implementation scheme, a mounting bracket is provided on the lamp body, and the mounting bracket is rotatably arranged with the lamp body.

[0027] By adopting the above technical solution, the lamp body is installed by installing the support, and the deflection angle of the lamp body along its own width direction is adjusted by rotating the lamp body, thereby improving the flexibility of lamp body adjustment.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. After the wall washer light is installed, first power on the base plate. Conductive wires are used between the base plates to make the lamp beads on the base plates light up. The light passes through the lens and becomes straight light to emit out of the lamp body. Then the driving assembly drives several base plates to rotate around the rotation axis through the connecting assembly to adjust the deflection angle of the base plates. The light emitted by the lens can be irradiated on the wall in the vertical direction, thereby adjusting the deflection angle of the wall washer light and making the lighting effect of the wall washer light more uniform.

[0030] 2. After the tilt angles of several substrates are adjusted, the adjustment rod is rotated, and the permanent magnet 1 or permanent magnet 2 on the adjustment rod adsorbs the adsorption block 1. Then the push plate pushes the adsorption block 1 to rotate. The adsorption block 1 drives the rotating shaft to rotate through the linkage rod and the rotating sleeve. The push block pushes the rotating block 1 or the rotating block 2, causing the pressing spring to contract, thereby achieving the adjustment of the deflection angle of a single substrate and improving the flexibility of substrate adjustment.

[0031] 3. The scattered light emitted by the lamp beads is blocked by the light-shielding tube, which effectively prevents the scattered light emitted by the lamp beads from affecting the brightness of the direct light extending from the lens. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating sleeve 444 is fixedly provided on the rotating shaft 152. The axis of the rotating shaft 152 is collinear with the axis of the rotating shaft 152. The rotating sleeve 444 is provided with an adsorption block 1 445 at the end facing the adjusting rod 41. The adsorption block 1 445 in this embodiment is an iron block. In other embodiments, In the example, the adsorption block 1 445 can be a magnet with opposite polarity to the permanent magnet 1 441 and the permanent magnet 2 443. A connecting rod 446 is fixed on the adsorption block 1 445. The connecting rod 446 is inserted into the rotating sleeve 444 and is slidably arranged along the axial direction of the rotating sleeve 444. A disassembly cavity 45 is provided in the rotating sleeve 444. The connecting rod 446 extends into the disassembly cavity 45. The connecting rod 446 is provided with an adsorption block 2 451 at one end extending into the disassembly cavity 45. The adsorption block 2 451 is an iron block.

The electromagnet 452 and the linear motor 21 are powered on and off at the same time.

[0049] When the inclination angles of several substrates 151 are adjusted, due to errors in processing and manufacturing, the light emitted from each lens 157 is not vertical. At this time, the electromagnet 452 is powered off, and the permanent magnet 1 441 or the permanent magnet 2 443 adsorbs the adsorption block 1 445 to the end face of the adjustment rod 41, and then the adjustment rod 41 is rotated.

The electromagnet 452 adsorbs the adsorption block 2 451, and the adsorption block 1 445 is disengaged from the adjustment rod 41, so that the transmission between the adjustment rod 41 and the rotating shaft 152 is released. At this time, the rotating shaft 152 of the individually adjusted substrate 151 rotates under the push of the clamping spring 39, so that the deflection angle of the individually adjusted substrate 151 is restored to the value before adjustment. Then the linear motor 21 drives several substrates 151 to adjust the new deflection angle at the same time, thereby improving the convenience of multiple adjustments of the light deflection angle.

[0051] The implementation principle of a wall washer lamp with adjustable light-emitting angle in an embodiment of the present application is as follows: when the lamp body 1 is installed on an inclined table, the substrate 151 is first energized, and the substrates 151 are electrically conductive through wires, the lamp beads 154 on the substrate 151 emit light, and the lens 157 emits light vertically out of the lamp body 1, and then the driving component 2 is turned on. The driving component 2 drives several substrates 151 to rotate around the rotating axis 152 along the length direction of the lamp body 1 through the connecting component 3, thereby realizing the adjustment of the deflection angle of the light emitted from the lamp body 1, so that the light can be vertically irradiated onto the wall on the inclined platform, thereby achieving a more uniform lighting effect of the wall washer lamp.
