Description

Technical Field

[0001] The present disclosure relates to the field of lighting technology, and in particular to an adjustable spotlight and a lighting system. Background Art

[0002] There are many lamps on the market, among which spotlights are mainly used in various occasions such as home, office, exhibition hall, shopping mall, etc. Spotlights can be placed on the ceiling, inside the wall, in the wall skirt or skirting, and the light is directly irradiated on the household objects that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve an artistic effect with prominent key points, unique environment, rich layers, strong atmosphere and colorful colors. Spotlights can play a leading role in the overall lighting, and can also provide local lighting, set off the atmosphere, and play the role of key lighting.

[0003] Currently, existing spotlights cannot achieve angle adjustment and cannot well meet users' needs for changing lighting angles.

[0004] Therefore, existing patent CN216280963U discloses a spotlight comprising a spotlight assembly, a height adjuster, a pre-assembled ring, and an angle adjuster. The angle adjuster comprises a base with a third hollow portion extending vertically through it, a rack at the top, and an incomplete gear structure mating with the rack at the bottom of the height adjuster. The rack is configured to mesh with the incomplete gear structure. As the incomplete gear structure moves on the rack, it drives the height adjuster to rotate within a certain angle, adjusting the height adjuster's angle and thus achieving the lighting angle adjustment effect of the spotlight.

[0005] However, when the spotlight is embedded in the main body of the building, when the height adjustment member is adjusted to drive the spotlight assembly to rotate to a certain angle, there is a situation where part of the light emitted by the spotlight assembly is emitted along the outer side of the angle adjustment member toward the installation groove of the main body of the building, rather than toward the outside of the main body of the building. As a result, there is a loss of luminous flux of the light going outside the main body of the building, that is, there is a problem of light leakage. Utility Model Content

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0042] The present disclosure provides an adjustable spotlight 10 according to an embodiment, which is used for installation in a building, and includes an optical assembly 100 , a lighting housing 200 , a concave member 300 , a light output cover 400 , and a mounting member 500 .

[0043] like Figures 1 to 4 、 Figure 7 As shown, the optical component 100 is installed in the lighting housing 200; the concave part 300 is installed on the optical component 100 and is located in the lighting housing 200; the light hood 400 is provided with a light outlet opening 401, the lighting housing 200 is movably connected to the outer wall of the light hood 400, and the concave part 300 is provided with a lighting mounting hole 301. At least part of the optical component 100 is passed through the lighting mounting hole 301, so that the concave part 300 and the optical component 100 are jointly covered on the light outlet opening 401, and then when the optical component 100 rotates about the rotation point formed between the lighting housing 200 and the light outlet cover 400, the concave part 300 always covers the light outlet opening 401; the mounting part 500 is installed on the outer peripheral wall of the light outlet cover 400.

[0044] In this embodiment, when adjusting the lighting angle of the optical assembly 100, regardless of the angle, the concave member 300 always covers the light output opening 401, thereby reducing the amount of light that escapes through the gap formed between the light output cover 400 and the concave member 301. When light is emitted from the optical assembly 100, it is always reflected by the light output cover 400 and then emitted to the outside through the opening of the light output cover 400. In this way, the adjustable spotlight 10 can reduce light loss. Specifically, the adjustable lighting angle can be adjusted to prevent light leakage, preventing some light from illuminating the interior of the building. This improves the lighting effect compared to existing technologies.

[0045] like Figure 3 、 Figures 6 to 11 As shown in one embodiment, the concave member 300 has an abutment ring 310, which is arranged adjacent to the lighting installation hole 301. The abutment ring 310 is used to abut against the side wall of the light outlet opening 401 when a first angle and a second angle are formed between the central axis of the lighting housing 200 and the central axis of the light outlet cover 400. It can be understood that when the first angle is formed between the lighting housing 200 and the light outlet cover 400, the semi-circumferential wall of the abutment ring 310 abuts against a side wall of the light outlet opening 401, and the effect is shown in the figure. Figure 7 and Figure 8 When the second angle is formed between the lighting housing 200 and the light emitting cover 400, the other half of the circumferential wall of the abutting ring 310 abuts against the other side wall of the light emitting opening 401, the effect diagram is as shown Figure 10 and Figure 11When the first angle and the second angle exist, the lighting housing 200 can rotate between the first angle and the second angle to adjust the lighting angle, and the concave member 300 completely covers the light outlet opening 401, and no gap is formed between the concave member 300 and the light outlet cover 400, thereby preventing light from leaking through the gap.

[0046] In this embodiment, a first angle α formed between the central axis of the lighting housing 200 and the central axis of the light output cover 400 is 135°, and a second angle formed between the central axis of the lighting housing 200 and the central axis of the light output cover 400 is 180°.

[0047] like Figures 3 to 5 As shown, in one embodiment, the lighting housing 200 includes a housing body 210 and a screw 220. The optical assembly 100 and the concave member 300 are located within the housing body 210. The housing body 210 is connected to the light hood 400 via the screw 220, so that the housing body 210 rotates with the screw 220 as the rotation point. Therefore, the housing body 210 rotates with the screw 220 as the rotation center. When the housing body 210 rotates, the optical assembly 100 and the concave member 300 rotate with the housing body 210 to adjust the lighting angle. Furthermore, the housing body 210 is provided with a relief hole 2101, and the light hood 400 is provided with a screw hole 402. The screw connection portion of the screw 220 is located in the relief hole 2101 and the screw hole 402, respectively. It can be understood that the housing body 210 only needs to be screwed to the outside of the light hood 400 via the screw 220, without adding any additional structure, making the lighting housing 200 more user-friendly and convenient to assemble and disassemble.

[0048] like Figure 1 As shown, in one embodiment, the housing body 210 is provided with a heat dissipation hole 211, which is disposed on a side of the housing body 210 away from the concave member 300. It will be appreciated that when the optical assembly 100 is in the lighting operation state, heat is generated, and this heat is dissipated through the heat dissipation hole 211 to ensure the normal operation of the optical assembly 100.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting member 500 includes a mounting platform 510 and a snap-on spring 520. The mounting platform 510 is mounted on the outer peripheral wall of the light output cover 400, and the snap-on spring 520 is connected to the outer wall of the mounting platform 510. It can be understood that the mounting platform 510 is used to engage with the building structure when the adjustable spotlight 10 is installed in the mounting groove of the building structure, and the snap-on spring 520 is used to snap on the inner wall of the mounting groove of the building structure to secure the entire lamp.

[0050] like Figure 1 and Figure 2As shown, in one embodiment, the mounting member 500 further includes a feedback protrusion 530, which is protruding from the outer wall of the mounting platform 510. It will be appreciated that when the adjustable spotlight 10 is installed in the mounting groove of a building structure, the feedback protrusion 530 abuts against the inner wall of the mounting opening when passing through the mounting opening of the building structure, providing installation feedback during the installation of the lamp, thereby improving the feedback performance of the lamp installation. The feedback protrusion 530 can also prevent the adjustable spotlight 10 from falling.

[0051] like Figure 1 As shown, in one embodiment, the snap-on spring piece 520 defines a clearance opening 5201, and the feedback protrusion 530 is disposed corresponding to the clearance opening 5201. It is understood that when installing the adjustable spotlight 10, the snap-on spring piece 520 is bent to allow it to enter the mounting groove of the building structure. During this process, the feedback protrusion 530 passes through the clearance opening 5201, allowing the clearance opening 5201 to function as a clearance, further ensuring that the adjustable spotlight 10 is installed in the mounting groove of the building structure.

[0052] The present disclosure also provides a lighting system, comprising the adjustable spotlight 10 according to any one of the above embodiments.

[0053] Compared with the prior art, the present disclosure has at least the following advantages:

[0054] In the adjustable spotlight 10 described above, the optical assembly 100 is installed in the lighting housing 200, and the concave member 300 is installed on the optical assembly 100. The lighting housing 200 is movably connected to the outer wall of the light hood 400. The light hood 400 has a light outlet opening 401. When the lighting angle of the optical assembly 100 is adjusted, no matter which lighting angle is adjusted, the concave member 300 always covers the light outlet opening 401, which can reduce the light from escaping through the gap formed between the light hood 400 and the concave member 300. When the optical assembly 100 emits light, it will always be reflected by the light hood 400 and then emitted to the outside through the opening of the light hood 400. In this way, the adjustable spotlight 10 can reduce light loss, that is, it can prevent light leakage after adjusting the lighting angle, preventing some light from illuminating the main body of the building. Therefore, compared with the existing technology, the lighting effect of this spotlight is better.

[0055] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
