The lamp 100 of the utility model can be compatible with a thinner light source board 23, thereby reducing costs, and can also avoid scratching the installer and the installation wall during the installation process.
[0035] A connecting seat 25 is provided on the side of the chassis 22 facing the rack 1. The connecting seat 25 is located in the middle of the chassis 22 and is used to cooperate with the rack 1. One of the connecting seat 25 and the rack 1 is provided with a hanging ear 251, and the other is provided with a slide 11. The slide 11 is for the hanging ear 251 to slide into, so as to realize the rotation snap connection between the chassis 22 and the rack 1. In this embodiment, the slide 11 is arranged on the rack 1, and is used to connect with the hanging ear 251. A first electrical connection part 252 is also provided on the connecting seat 25, and a second electrical connection part 12 is correspondingly provided on the rack 1. The first electrical connection part 252 and the second electrical connection part 12 are configured to be plugged in up and down to realize electrical connection, supply power to the light source panel 23, and realize lighting. The connecting seat 25 and the rack 1 can be existing technologies, as long as they can realize suspension and electrical connection, and there is no limitation on this.
[0036] The orthographic projection of the light source board 23 on the chassis 22 is located at the periphery of the orthographic projection of the connecting seat 25 on the chassis 22, which is convenient for heat dissipation. The light source board 23 is provided with a plurality of evenly arranged lamp beads 231, so that the light output of the light source board 23 is more uniform. In this embodiment, the light source board 23 is provided with three and combined with each other to form a circular ring-shaped whole, and the whole is fixedly connected to the chassis 22; of course, in other embodiments, the light source board 23 can also be directly provided in a circular ring shape without being divided into multiple parts, as long as uniform light output can be achieved. The lampshade 3 includes a frame 31 and a light-transmitting cover 32. The frame 31 is arranged around the periphery of the chassis 22 and is fixedly connected to the chassis 22. The light-transmitting cover 32 is snap-fitted with the frame 31 to achieve fixation.
[0037] like Figure 3-Figure 8As shown, the chassis 22 is provided with a plurality of through mounting holes; the light source board 23 is installed on the chassis 22, and the light source board 23 is provided with a plurality of through fixing holes; the fixing member 24 is fixed to the side of the light source board 23 away from the chassis 22, and the fixing member 24 is provided with a fastening hole; the mounting hole, the fixing hole and the fastening hole are aligned with each other, and the fastener 21 passes through the mounting hole, the fixing hole and the fastening hole in sequence to connect and fix the chassis 22 and the light source board 23. In this embodiment, the fastener 21 passes through the chassis 22, the light source board 23 and the fixing member 24 in sequence, and the fastener 21 is connected with the fixing member 24 in cooperation to fix the light source board 23 on the chassis 22, and the fastener 21 includes but is not limited to screws or rivets, as long as a fixed connection can be achieved. The fixing member 24 can increase the thickness of the light source board 23. When the fastener 21 penetrates the fixing member 24, the contact height between the light source board 23 and the fastener 21 is increased to ensure a stable connection. Meanwhile, the fixing member 24 can also disperse the stress on the light source board 23 to increase the service life of the light source board 23.
[0038] The fastener 21 includes a head 211 and a shaft 212. The head 211 is exposed on the outer surface of the chassis 22. A threaded structure (not shown) is provided on the outer periphery of the shaft 212. The shaft 212 passes through the chassis 22, the light source board 23 and the fixing member 24 in sequence. A conical portion 2121 is provided at one end of the shaft 212 away from the head 211. The conical portion 2121 is connected to the head 211 through an extension portion 2122. The conical portion 2121 passes through the fastening hole. The inner diameter of the fastening hole is smaller than the outer diameter of the extension portion 2122. In this embodiment, the threaded structure can be provided only on the outer periphery of the extension portion 2122. The conical portion 2121 mainly plays a guiding role. When installing the fastener 21, since the inner diameter of the fastening hole is smaller than the outer diameter of the extension 2122, the tapered portion 2121 will first penetrate into the fastening hole. As the fastener 21 penetrates deeper, the extension 2122 can penetrate into the fastening hole due to its threaded structure until the tapered portion 2121 is completely exposed to the fixing member 24. To ensure reliable connection, the fastener 21 has a torque requirement. By fastening the fastener 21 with a thicker fixing member 24, the thickness requirement of the light source board 23 can be greatly reduced.
[0039] Specifically, a connection structure (not shown) is provided on the light source board 23, and the connection structure is located on the side of the fixing hole away from the chassis 22, so that the fixing member 24 can be fixedly connected to the light source board 23 through the connection structure. In other words, the connection structure is exposed on the light source board 23, and the fixing member 24 is mechanically connected to the light source board 23 through the connection structure.
[0040] Preferably, in this embodiment, the light source board 23 is a multi-layer structure, including a substrate, an insulating layer laid on the substrate, and a conductive layer laid on the insulating layer, the conductive layer is provided with a conductive area and a non-conductive area, the connecting structure is pre-set on the conductive layer, and is integrally formed in the non-conductive area of the light source board 23, that is, the connecting structure is insulated from the conductive area of the light source board 23. The connecting structure is arranged in an annular shape and is arranged around the periphery of the fixing hole, and the fixing member 24 is also arranged in an annular shape accordingly, so as to facilitate welding of the fixing member 24 and the connecting structure, and the fixing member 24 is overall smaller and thicker.
[0041] In this embodiment, the connection structure is copper foil, and the fixing member 24 is an annular metal sheet. The copper foil is pre-tinned and then welded to the annular metal sheet. Specifically, the surface of the copper foil is pre-tinned to form a tin hole, i.e., a fixing hole. At this time, no curing treatment is performed. The annular metal sheet is placed above the tin hole through an automatic patch device, and the tin layer is cured through a reflow soldering device to bond the light source board 23 and the annular metal sheet, so that the fixing member 24 is fixedly connected to the light source board 23, and the thickness of the light source board 23 is increased in a targeted manner, and the contact height between the fastener 21 and the light source board 23 is increased to ensure reliable connection. At the same time, the fixing member 24 can also disperse the stress on the light source board 23. The tin layer is equivalent to glue in this embodiment.
[0042] Of course, in other embodiments, the connection structure may be other, not limited to copper foil. Alternatively, when the fixing member 24 is fixedly connected to the light source board 23, one end of the fixing member 24 may be directly clamped and embedded in the fixing hole to increase the thickness of the light source board 23 and meet the requirement of stable connection of the fastener 21, and there is no limitation on this.
[0043] In another embodiment, the connection structure is copper foil, and the fixing member 24 is replaced by a tin block, that is, the fixing member 24 is a tin block accumulated around the fixing hole. Specifically, more unmelted solder paste is laid on the surface of the copper foil, and after reflow soldering, the solder paste shrinks and condenses, and accumulates around the fixing hole to form a tin block, thereby thickening the contact height between the light source board 23 and the fastener 21, achieving reliable connection and dispersing stress. When the fixing member 24 is a tin block, it is more convenient to weld the fixing member 24 to the copper foil.
[0044] In summary, the lamp 100 of the present invention fixes the fixing member 24 on the side of the light source board 23 away from the chassis 22, so that the fastener 21 can sequentially pass through the mounting hole on the chassis 22, the fixing hole on the light source board 23 and the fastening hole on the fixing member 24, thereby connecting and fixing the chassis 22 and the light source board 23. The lamp 100 of the present invention can be compatible with thinner light source boards 23, reduce costs, and avoid scratching the installer and the installation wall during the installation process.
[0045] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
