Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a downlight with an adjustable light emission angle. Background Technology

[0002] Downlights are recessed lighting fixtures primarily used to provide general lighting, localized accent lighting, and decorative lighting. They can evenly illuminate a space to meet the needs of daily activities, while also focusing light to highlight specific areas or objects, such as artwork or display cases. Downlights come in a variety of designs, enhancing the aesthetics of a space and creating ambiance. Their recessed installation saves space and is suitable for low ceilings.

[0003] In existing technology, downlights include a mounting frame and a lamp body. During construction and decoration, the mounting frame needs to be embedded in the ceiling to reduce the adverse effects of uneven ceiling openings on the visual effect. Downlights often need to be adjusted in their illumination direction before the completion of construction and decoration to meet the specific lighting needs of users. For example, see the utility model patent with publication number CN202065849U, entitled "A Height-Adjustable Circular LED Downlight".

[0004] Regarding the aforementioned technologies, the mounting bracket is typically positioned in front of the light source's illumination direction to shield against uneven, porous surfaces. However, in practice, the applicant has found that after adjusting the light source's illumination direction, the mounting bracket easily obstructs the light emitted by the light source, resulting in a discrepancy between the lighting effect and expectations. Summary of the Invention

[0005] To ensure that the light from the downlight is not easily blocked by the mounting bracket when adjusting the light emission angle, this application provides a downlight with an adjustable light emission angle.

[0006] The technical solution of the adjustable beam angle downlight provided in this application is as follows: an adjustable beam angle downlight, including a fixed frame, a lamp body and a hinge plate;

[0007] The fixed frame is provided with a through-hole for the lamp body and the light from the lamp body to pass through;

[0008] The hinge plate is fitted to the fixed frame in a rotatable and sliding manner. The lamp body is mounted on the hinge plate, and the lamp body can pass through the illumination hole through the adjustment of the hinge plate.

[0009] By adopting the above technical solution, the light output angle of the lamp can be adjusted according to the actual usage scenario before the lamp is installed in the recess. Since the lamp body is detachably fixed on the hinge plate, first adjust the sliding fit between the hinge plate and the fixed frame, then adjust the rotation fit between the hinge plate and the fixed frame, and finally achieve the effect of adjusting the light output angle of the downlight. Moreover, the light from the downlight is not easily blocked by the fixed frame.

[0010] Optionally, the fixed frame is slidably fitted with an adjusting slider, and the hinge plate is mounted to the adjusting slider by adjusting bolts.

[0011] By adopting the above technical solution, the adjusting bolt is used to adjust the rotational fit of the lamp body: loosening the adjusting bolt between the hinge plate and the adjusting slider allows the hinge plate to rotate around the adjusting bolt by a certain angle, thereby achieving the effect of adjusting the light output angle of the downlight.

[0012] Optionally, the fixed frame has a guide rail groove, and the adjusting slider is located inside the guide rail groove. The adjusting slider is elastic and fits tightly against the groove wall of the guide rail groove.

[0013] By adopting the above technical solution, the guide rail groove of the fixed frame and the adjusting slider are interference fit: by applying pressure to the adjusting slider, the elastic deformation of the adjusting slider is caused, that is, friction is generated between the adjusting slider and the guide rail groove, thereby achieving the effect of moving and stopping the lamp body.

[0014] Optionally, the lamp body has a reduced end and an enlarged end, with the reduced end being farther away from the illumination hole than the enlarged end.

[0015] By adopting the above technical solution, the design of the extended end can not only more accurately constrain the light and form a downward concentrated beam of light to avoid light scattering to the side, but also provide a wider adjustment space for the downlight when adjusting the light output angle, and it is not easily blocked by the fixed frame.

[0016] Optionally, the lamp body is detachably mounted to the hinge plate.

[0017] By adopting the above technical solution, the lamp body can be detachably installed on the hinge plate, which facilitates the replacement of the lamp body and reduces the need to replace the entire downlight.

[0018] Optionally, the hinge plate is provided with a plurality of pin holes, each pin hole having a plug-in portion and a snap-fit ​​portion, the width of the plug-in portion being greater than the width of the snap-fit ​​portion;

[0019] The lamp body is provided with a snap-fit ​​protrusion, which is engaged with the plug-in part, and the snap-fit ​​protrusion can slide to the snap-fit ​​part and engage with the snap-fit ​​part after being inserted into the plug-in part.

[0020] By adopting the above technical solution, the stability of the lamp body on the hinge plate can be guaranteed, and the replacement of the light source can be facilitated. That is, it is not necessary to break the ceiling to remove the downlight to replace the light source. Simply rotate the downlight embedded in the ceiling, that is, rotate the snap-fit ​​protrusion from the snap-fit ​​part to the plug part to the pin hole, and the lamp body can be replaced. The technical solution can reduce labor costs and improve economic efficiency.

[0021] Optionally, the fixed frame has a through bolt rotation hole, which is connected to the guide rail groove and extends along the sliding direction of the adjusting slider.

[0022] By adopting the above technical solution, when adjusting the rotation of the lamp body, the tightness of the adjusting bolt can be adjusted through the bolt rotation hole, which is simple and convenient to adjust.

[0023] Optionally, the guide rail groove is provided with a friction layer inside, and the two sides of the adjusting slider are respectively abutted against the friction layer and the groove wall of the guide rail groove.

[0024] By adopting the above technical solution, when the adjusting slider is in interference fit with the guide rail groove, it can protect the adjusting slider and the guide rail groove, reduce the impact on the guide rail groove and itself when the adjusting slider returns to its original shape after the lamp body has completed displacement, and improve the service life of the product.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Before installing the recessed lamp, the light output angle of the lamp can be adjusted according to the actual usage scenario. Since the lamp body is detachably fixed on the hinge plate, first adjust the sliding fit between the hinge plate and the fixed frame, and then adjust the rotation fit between the hinge plate and the fixed frame. Finally, the light output angle of the downlight can be adjusted, and the light from the downlight is not easily blocked by the fixed frame.

[0027] 2. When the light source needs to be replaced, it is not necessary to break the ceiling and remove the downlight to replace the light source. Simply rotate the downlight embedded in the ceiling, that is, rotate the snap-fit ​​protrusion from the snap-fit ​​part to the plug part to the pin hole, and the light body can be replaced. Through technical solutions, labor costs are reduced, thereby improving economic efficiency.

[0028] 3. When the adjusting slider is in an interference fit with the guide rail groove, the friction layer can protect the adjusting slider and the guide rail groove, reduce the impact on the guide rail groove and itself when the adjusting slider returns to its original shape after the lamp body has completed its displacement, and improve the service life of the product.

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] Example 1:

[0039] Embodiment 1 of this application discloses a downlight with an adjustable light emission angle, referencing... Figure 1 It includes a fixed frame 1, a lamp body 2, and a hinge plate 3;

[0040] Reference Figure 1 and Figure 2 The mounting frame 1 has a through-hole 101 for the light from the lamp body 2 to pass through. A hinge plate 3 is fitted to the mounting frame 1 in a rotatable and sliding manner. The lamp body 2 is mounted on the hinge plate 3; that is, by rotating and sliding the hinge plate 3, the position and illumination angle of the lamp body 2 are changed, allowing the lamp body 2 to pass through the through-hole 101, reducing the obstruction of light by the mounting frame 1. The mounting frame 1 not only conceals irregular edges or cracks that may result from ceiling openings, as well as non-decorative components inside the downlight, but also increases the contact surface with the ceiling, distributing pressure and preventing localized stress that could cause ceiling deformation or cracking.

[0041] Reference Figure 1 and Figure 3The fixed frame 1 is slidably fitted with an adjusting slider 11, and the hinge plate 3 is mounted on the adjusting slider 11 via an adjusting bolt 12. In Embodiment 1 of this application, when the hinge plate 3 and the adjusting slider 11 are connected by the adjusting bolt 12, a nut and an elastic washer are also provided to ensure that the hinge plate 3 is tightly fitted against one side of the adjusting slider 11 by the adjusting bolt 12, and that the nut is tightly fitted against the other side of the adjusting slider 11. Furthermore, the elastic washer ensures that the torque of the adjusting bolt 12 meets the requirements, reducing the possibility of the adjusting bolt 12 and nut becoming loose.

[0042] The adjusting slider 11 is elastic and preferably made of metal. The material of the adjusting slider 11 is spring steel or stainless steel of Japanese Industrial Standard SUS316. Both spring steel and SUS316 stainless steel are suitable for structures that bear dynamic loads, and compared with ordinary carbon steel, they are not easy to break under long-term alternating stress and have better corrosion resistance.

[0043] Reference Figure 3 The fixed frame 1 has a guide rail groove 102, and the adjusting slider 11 is located inside the guide rail groove 102. The elastic adjusting slider 11 is tightly fitted against the groove wall of the guide rail groove 102, and the guide rail groove 102 can slide along its length direction by external force. The guide rail groove 102 and the adjusting slider 11 of the fixed frame 1 are interference fit: by applying pressure to the adjusting slider 11, elastic deformation of the adjusting slider 11 is caused, that is, friction is generated between the adjusting slider 11 and the guide rail groove 102, thereby achieving the effect of moving and stopping the lamp body 2.

[0044] Reference Figure 4 The lamp body 2 has a narrowed end and an enlarged end, with the narrowed end being farther away from the illumination hole 101 than the enlarged end. The diameter of the narrowed end of the lamp body 2 is smaller than the diameter of the enlarged end. In Embodiment 1 of this application, the lamp body 2 is specifically arranged in a frustum-cone shape. This frustum-cone shape not only allows for more precise light control, forming a downward-concentrated beam of light and preventing light scattering to the sides, but also provides a wider adjustment space for the downlight when adjusting the light emission angle, without being blocked by the mounting frame 1.

[0045] Reference Figure 5The hinge plate 3 has two through-holes 310, each with a insertion portion 311 and a locking portion 312. The locking portion 312 connects to the insertion portion 311, and the width of the insertion portion 311 is greater than the width of the locking portion 312. The lamp body 2 has two locking protrusions 21, which are respectively inserted into the insertion portions 311 of each of the through-holes 310. After being inserted into the insertion portion 311, the locking protrusion 21 can slide to the locking portion 312 and engage with it, thereby allowing the lamp body 2 to be detachably locked to the hinge plate 3. In embodiment 1 of this application, the locking protrusion 21 is specifically an adjusting bolt 12, and it engages with the locking portion 312 through the nut of the adjusting bolt 12. By inserting the snap-fit ​​protrusion 21 into the insertion part 311 and rotating it, the lamp body 2 is connected to the hinge plate 3. This ensures the stability of the lamp body 2 on the hinge plate 3 and facilitates the replacement of the light source. That is, it is not necessary to break the ceiling and remove the downlight to replace the light source. Simply rotate the downlight embedded in the ceiling, that is, rotate the two snap-fit ​​protrusions 21 from the snap-fit ​​part 312 to the insertion part 311 to the pin hole 310, and the lamp body 2 can be replaced. This technical solution can reduce labor costs and improve economic efficiency.

[0046] The implementation principle of an adjustable downlight according to Embodiment 1 of this application is as follows: Before the downlight is embedded in the ceiling, the light emission angle of the lamp body 2 can be adjusted in advance as needed. Because the lamp body 2 is fixed to the hinge plate 3 by a two-point pin design, and the hinge plate 3 is engaged with the adjusting slider 11 in the fixed frame 1 by rotation and sliding, adjusting the hinge plate 3 is equivalent to adjusting the lamp body 2. First, by applying pressure to the hinge plate 3, the adjusting slider 11 slides in the track groove of the fixed frame 1, and then the lamp body 2 protrudes a certain distance from the fixed frame 1. This ensures that after adjusting the light emission angle of the lamp body 2 in the next step, the light is not easily blocked by the fixed frame 1.

[0047] Example 2:

[0048] Embodiment 2 of this application discloses a downlight with an adjustable light emission angle, which, in addition to all the technical features of Embodiment 1, also includes the following technical features:

[0049] Reference Figure 6 and Figure 7 A friction layer 13 is fixedly disposed inside the guide rail groove 102. The two sides of the adjusting slider 11 are respectively pressed against the friction layer 13 and the groove wall of the guide rail groove 102, so as to increase the friction force inside the guide rail groove 102 through the friction layer 13, making it less likely to loosen when installing a heavy lamp body 2. For example, the material of the friction layer 13 can be a material with a high coefficient of friction, such as soft rubber or soft silicone.

[0050] In addition, the fixed frame 1 is also provided with a bolt rotation hole 103, which is connected to the guide rail groove 102 and extends along the sliding direction of the adjusting slider 11. The bolt rotation hole 103 allows construction and decoration personnel to adjust the tightness of the adjusting bolt 12 or nut through the bolt rotation hole 103, thereby facilitating the adjustment of the position and orientation of the lamp body 2 during the construction and decoration process.

[0051] The implementation principle of an adjustable downlight according to Embodiment 2 of this application is as follows: After the lamp body 2 is adjusted, the adjusting bolt 12 is loosened from the bolt rotation hole 103 to make a fine adjustment to the light emission angle of the downlight. After the fine adjustment, the adjusting bolt 12 is tightened again, and finally the downlight is embedded into the ceiling, which is beneficial to the construction work of the decorators.

[0052] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
