Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a reflector mounting structure and a lamp comprising the structure. Background Art

[0002] LED lighting, with its low energy consumption, environmental friendliness, and long lifespan, is a mainstream product in the current lighting market. Currently, LED spotlights are widely used in general indoor lighting scenarios, such as homes, shopping malls, and hotels. Spotlights typically have a reflector on their light-emitting surface to meet light distribution requirements. Currently, spotlight reflectors are typically connected directly to the rotating frame with snap-ons, or to the face ring with snap-ons. These snap-on installations require alignment, requiring the snaps to be aligned before the reflector is pushed in and snapped into place, resulting in low installation efficiency. When a spotlight requires repair, customers must first remove the reflector to access the lamp head. However, overtightening the snaps often makes removal difficult and can even cause breakage of the lamp components. Furthermore, the reflector, a secondary light distribution element, leaves a gap between the reflector and the lens' light-emitting surface. When the lamp is on, some light enters the gap between the reflector and the face ring. If the gap is large, light can escape, resulting in light leakage and a poor user experience.

[0025] The reflector mounting structure and the lamp proposed in the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Figure 1 This is a schematic structural diagram of a lamp according to a preferred embodiment of the present application. Figure 2This is a cross-sectional view of the embodiment, which is a spotlight. As shown in the figure, the lamp includes a lamp body 1 and a light source 5 arranged in the lamp body. The lamp body 1 includes a bottom shell 101, a middle ring 102, and a surface ring 103. The middle ring 102 and the surface ring 103 are fixedly connected by a snap fastener, and the surface ring 103 includes a light outlet 1031. The bottom shell 101 includes a bottom surface 1011, and the light source 5 is arranged on the bottom surface 1011 and emits light facing the light outlet 1031. The bottom shell 101 is sleeved in the middle ring 102, and the bottom shell 101 is pivotally connected to the middle ring 102 by a rotating shaft 8, and the rotating shaft 8 is perpendicular to the axis of the light outlet 1031. The bottom shell 101 can rotate along the rotating shaft 8 relative to the middle ring 102 and the surface ring 103 to adjust the illumination angle of the light source 5, thereby achieving the adjustment of the angle of the light output of the spotlight.

[0027] The face ring 103 is also equipped with a spring assembly 9 for securing the lamp to the mounting surface. Spotlights are typically mounted on a surface such as a ceiling or suspended ceiling. During installation, a hole is first drilled in the mounting surface, through which the lamp body 1 is inserted. The spring assembly 9 and face ring 103 are then positioned on either side of the mounting surface, sandwiching the surface to secure the lamp.

[0028] In this embodiment, the reflector 2 and the lamp body 1 are detachably connected by the reflector mounting structure proposed in this application. Specifically, the magnetic connection is achieved by a first connecting member 4 and a second connecting member 3 that can be attracted to each other. Figure 9 、 Figure 10 The above-mentioned is a small magnet. A connecting platform 104 facing the light outlet 103 is provided on the inner side of the lamp body 1. In order to fix the first connecting member 4, as shown in FIG. Figure 10 As shown, a mounting hole 105 is formed in the connecting platform 104. During installation, liquid glue is first filled into the mounting hole 105, and then the first connecting member 4 is inserted into the mounting hole 104. After the glue solidifies, the first connecting member 4 is fixed in the mounting hole 105. To ensure reliable adsorption, it is best to keep the engaging surface of the first connecting member 4 slightly protruding from the connecting platform 104 when it is inserted into the mounting hole 105.

[0029] The second connecting member 3 is as follows Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, it is annular and is sleeved on the outside of the reflector 2. As a light control element, the reflector 2 is usually in the shape of a cone, including two ports of different sizes. The small end is the light entrance side and is located close to the light source 5, and the large end is the light exit side. In this embodiment, the large end of the reflector 2 is located at the light exit 1031 of the lamp body 1. In order to fix the second connecting member 3, as shown in FIG. Figure 3 、 Figure 4As shown, the outer surface of the reflector 2 is provided with a first clamping portion 201 and a second clamping portion 202. The first clamping portion 201 and the second clamping portion 202 are spaced apart from each other in the direction from the larger end to the smaller end of the reflector 2, i.e., there is a gap between them in the axial direction. This allows the second connector 3 to be positioned within this gap, so that the first clamping portion 201 and the second clamping portion 202 can clamp the second connector 3 from both the upper and lower sides. In this embodiment, both the first clamping portion 201 and the second clamping portion 202 are in the form of claws. The first clamping portion 201 comprises at least two first claws protruding radially outward from the outer surface of the reflector 2, and the second clamping portion comprises at least two second claws protruding radially outward from the outer surface of the reflector 2. The claws are evenly distributed along the circumference of the outer surface of the reflector 2. In this embodiment, both the first clamping portion 201 and the second clamping portion 202 are provided with two claws. In other preferred embodiments, the number of claws may be greater, and this application is not limited thereto. The first claw forming the first clamping portion 201 and the second claw forming the second clamping portion 202 are arranged in pairs and staggered in the axial direction of the reflector 2, that is, the first clamping portion 201 and the second clamping portion 202 do not overlap in the vertical direction, which facilitates the installation of the second connecting member 3 and ensures a reliable connection.

[0030] The cross section of the second connecting member 3 is as follows Figure 6 As shown, it is Z-shaped and includes a snap ring surface 303, a bent connection portion 301, and a connecting ring surface 302 connected in sequence. The snap ring surface 303 is set at the innermost side of the ring and is connected to the connecting ring surface 302 by the bent connection portion 301. The snap ring surface 303 and the connecting ring surface 302 are not in the same plane. During installation, the snap ring surface 303 is close to the reflector 2 and is clamped by the first snap part 201 and the second snap part 202, while the connecting ring surface 302 is closer to the first connecting member 4 than the snap ring surface 303. Figure 10 As shown, the connecting ring surface 302 is slightly higher than the upper surface of the second clamping portion 202. This allows the first connector 4 to adhere to the connecting ring surface 302 during magnetic connection, ensuring a secure connection. In this embodiment, the second connector 3 is a stamped circular iron ring. The Z-shaped cross-section not only prevents interference between the second clamping portion 202 and the magnetic connection surface, but also increases component strength.

[0031] To ensure a secure connection between the second connector 3 and the reflector 2, a support portion 203 extending upward from the larger end of the reflector 2 may be provided on the outer surface of the reflector 2. The upper surface of the support portion abuts the lower side of the connecting annular surface 302 in the second connector 3. Furthermore, to support the second connector 3 and prevent it from shaking, a plurality of arcuate ribs 204 extending from the larger end to the smaller end are provided on the outer inclined surface of the reflector 2. To limit circumferential displacement of the second connector 3, a positioning notch 304 is provided on the outer circumference of the second connector 3. Positioning bumps 205 are also provided on the outer surface of the reflector 2. During installation, the positioning bumps 205 are inserted into the positioning notches 304 to achieve positioning.

[0032] like Figure 2 As shown, the embodiment of the lamp includes a two-stage light distribution system. A lens 6 is mounted on the light source 5 to achieve primary light distribution. A grille 7 is also positioned on the light-emitting side of the lens 6 to provide anti-glare. Both the lens 6 and grille 7 are located within the bottom housing 101. Light emitted from the light source 5 first passes through the lens 6 and grille 7 before passing through the reflector 2 for secondary light distribution. The reflector 2 is mounted above the center ring 102. The bottom housing 101 and center ring 102 are connected by a rotating shaft 8, allowing for relative rotation. Consequently, a gap exists between the small end light inlet of the reflector 2 and the light-emitting side of the lens 6. Some light emitted by the lens 6 can escape along the outer inclined surface of the reflector 2 through the gap between the face ring 103 and the light-emitting port 1031 of the reflector 2, resulting in light leakage. In this embodiment, a second connector 3 is included, which fits over the outer inclined surface of the reflector, blocking this light leakage and preventing it.

[0033] In this embodiment, the reflector 2 is magnetically connected to the lamp body 1. For removal, simply grasp the small end of the reflector 2 and apply a slight force, providing a comfortable feel. The first connecting member 4 is a magnet embedded in the connecting platform 104, and the second connecting member 3 is an iron ring. The magnet and the iron ring are magnetically connected to achieve installation of the reflector 2. In other preferred embodiments, one of the first connecting member 4 and the second connecting member 3 is a strong magnet, while the other is a magnetic metal material, and the two are interchangeable. For example, an iron block may be provided on the lamp body 1, while the second connecting member 3 is a raised ring extending radially from the outside of the reflector 2 and having a magnet mounted thereon.

[0034] This embodiment is a spotlight, and the connecting platform 104 is arranged on the middle ring 102 of the lamp body 1. The reflector mounting structure proposed in this application can also be applied to other types of lamps. In other preferred embodiments, the structure of the reflector 2 will not be much different, so the second connecting member 3 is arranged as above, the difference is that the first connecting member 4 can be arranged in the corresponding position of other types of lamps. Since the reflector 2 is always a structure that is larger at the bottom and smaller at the top, a connecting platform 104 that is no larger than the light outlet 1031 of the reflector 2 can always be set in the space on the inner side of the lamp body 1 for accommodating the reflector 2 to set the first connecting member 4. The addition of the connecting platform 104 does not cause the volume of the lamp body 1 to increase.

[0035] The above description of the preferred embodiments of the present invention is for illustration and description purposes and is not intended to be exhaustive or limited to the specific forms disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included within the scope of the present invention as defined by the appended claims.
