Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to a suspended spherical lamp. Background Technology

[0002] Pendant spherical lights, a common type of indoor and outdoor lighting fixture, are widely used for ceiling lighting in homes, commercial spaces, and public places due to their even and soft light distribution and aesthetically pleasing design. Traditional pendant spherical lights typically consist of a lamp holder (containing a light source, optical components, and electrical parts), a connecting rod, and a mounting bracket. The lamp holder is fixed to the mounting bracket via the connecting rod, and the mounting bracket is fixed to the ceiling or wall surface.

[0003] Existing suspended spherical lights often have the following shortcomings in the connection structure between the connecting rod and the lamp head:

[0004] First, installation and disassembly are inconvenient.

[0005] The method of fixing the connecting rod to the lamp holder (such as screws, clips, etc.) may be complicated, requiring additional tools and operating steps, which can cause inconvenience to installation and maintenance (such as replacing the light source or lamp holder).

[0006] Second, electrical connections are separated.

[0007] The connection of the positive and negative power terminals required for the light source inside the lamp holder (usually from the connecting rod or the wire passing through the connecting rod) and the mechanical fixing of the lamp holder are typically two separate steps. During installation, the power cord needs to be connected separately (such as plugging in the terminal, tightening the wire screws, etc.) after the mechanical fixing is completed. This increases the complexity of installation and the risk of errors (such as reversing the positive and negative terminals), and also makes the internal wiring of the lamp less neat, which may affect the heat dissipation space or aesthetics.

[0008] Therefore, developing a hanging spherical lamp connection structure that simplifies the installation and disassembly process, reliably completes electrical connections, and maintains simple internal wiring has practical application value. Utility Model Content

[0009] This utility model designs a suspended spherical lamp, which solves the technical problem that existing suspended spherical lamps have defects such as inconvenient installation and disassembly and separation of electrical connections.

[0010] To solve the aforementioned technical problems, the present invention adopts the following solution:

[0011] A suspended spherical lamp includes a lamp head, a connecting rod, and a mounting bracket. The lamp head is connected to the mounting bracket via the connecting rod. The lamp head includes a lamp housing, a lens cover, a light source, and a light source fixing plate. The light source is fixed on the bottom surface of the light source fixing plate, and the lens cover is located below the light source. The light source fixing plate is characterized by: a first boss and a second boss on its top surface; threaded holes on the first boss and the second boss; a first fixing screw engaging with the threaded hole of the first boss, and a second fixing screw engaging with the threaded hole of the second boss; a pressure plate bottom surface supported on the first boss and the second boss, and the top surface of the pressure plate passing through the first boss... A fixing screw is fixed to a second fixing screw; the connecting rod includes a horizontal pressing fixing part and a vertical part; the horizontal pressing fixing part is located between the first boss and the second boss, and is clamped and fixed between the pressure plate and the light source fixing plate; the top of the horizontal pressing fixing part is provided with an upper negative electrode contact, and the bottom is provided with a lower positive electrode contact; the bottom of the pressure plate is provided with a negative electrode plate, which contacts the upper negative electrode contact and extends through the second boss and the light source fixing plate to connect with the negative electrode of the light source; the top surface of the light source fixing plate is provided with a positive electrode plate, which contacts the lower positive electrode contact and extends through the light source fixing plate to connect with the positive electrode of the light source.

[0012] Preferably, the first boss and the second boss have notches, so that the top surface of the pressure plate, the top surface of the first boss, and the top surface of the second boss are flush.

[0013] Preferably, the horizontal pressing and fixing part is a sheet-like or plate-like structure, and its width is adapted to the distance between the first boss and the second boss.

[0014] Preferably, the light source is an LED light source module.

[0015] Preferably, the mounting bracket includes a base plate for fixing to the top of a ceiling or wall, and a mounting interface for connecting to the vertical portion of the connecting rod.

[0016] Preferably, the connection between the mounting bracket and the vertical part of the connecting rod is a rotatable connection to adjust the illumination angle of the lamp head.

[0017] Preferably, the negative electrode sheet is positioned on the bottom surface of the pressure plate in a manner corresponding to the second protrusion area and avoiding the position of the first fixing screw.

[0018] This suspended spherical light has the following beneficial effects:

[0019] (1) The horizontal pressing and fixing part of this utility model is clamped between the pressure plate and the light source fixing plate. Only the first and second fixing screws need to be locked to complete the mechanical fixing and circuit conduction simultaneously, completely eliminating the step-by-step operation of traditional lamps of "installing the bracket first and then connecting the wires", reducing installation time.

[0020] (2) The upper negative contact and the lower positive contact of this utility model are spatially isolated to achieve insulation. The negative electrode plate of the pressure plate can only contact the upper negative contact, and the positive electrode plate of the light source fixing plate can only contact the lower positive contact, thus avoiding short circuits or damage to the light source caused by reverse polarity.

[0021] (3) The positive and negative electrode plates of this utility model are directly connected to the light source fixing plate and the pressure plate, serving as both structural and conductive components; the connecting rod contacts are in contact with the power supply plate plane, eliminating the need for plug-in terminals and soldering points, thus reducing the circuit failure rate.

Detailed Implementation

[0029] The following is combined with Figures 1 to 5 The present invention will be further described below:

[0030] like Figure 1 As shown, a suspended spherical lamp includes a lamp head 1, a connecting rod 2, and a mounting bracket 3. The lamp head 1 is connected to the mounting bracket 3 via the connecting rod 2, and the mounting bracket 3 is fixed to the top surface of a wall. The mounting bracket 3 includes a base plate for fixing to the ceiling or top of a wall, and a mounting interface for connecting to the vertical portion of the connecting rod 2. The connection between the mounting bracket 3 and the vertical portion of the connecting rod 2 is rotatable to adjust the illumination angle of the lamp head 1.

[0031] like Figure 2As shown, the lamp holder 1 includes a lamp housing, a lens cover 11, a light source 12, and a light source fixing plate 13. The light source 12 is fixed on the bottom surface of the light source fixing plate 13, and the lens cover 11 is located below the light source 12. The assembly of the lens cover 11, the light source 12, and the light source fixing plate 13 is located in the lamp housing. The light source 12 is an LED light source module.

[0032] like Figure 3 As shown, the inventive point of this invention lies in the connection structure between the connecting rod 2 and the lamp holder 1. This connection structure not only allows for easy installation and disassembly of both, but also ensures the correct connection of the positive and negative poles of the light source during installation.

[0033] like Figures 4-5 As shown, the specific structure of the connection between the connecting rod 2 and the lamp holder 1 is as follows: A first protrusion 15 and a second protrusion 16 are provided on the top surface of the light source fixing plate 13. The first protrusion 15 and the second protrusion 16 are provided with threaded holes. A first fixing screw 17 engages with the threaded hole on the first protrusion 15, and a second fixing screw 18 engages with the threaded hole on the second protrusion 16. The first protrusion 15 and the second protrusion 16 support both sides of the bottom surface of the pressure plate 14, and the top surface of the pressure plate 14 is fixed by the first fixing screw 17 and the second fixing screw 18. There are notches in the first protrusion 15 and the second protrusion 16 so that the top surface of the pressure plate 14, the top surface of the first protrusion 15, and the top surface of the second protrusion 16 are flush. The connecting rod 2 includes a horizontal pressing and fixing part 21 and a vertical part. The vertical part is connected to the mounting bracket. The horizontal pressing and fixing part 21 is located between the first protrusion 15 and the second protrusion 16, and the horizontal pressing and fixing part 21 is clamped and fixed between the pressure plate 14 and the light source fixing plate 13.

[0034] The horizontal pressing and fixing part 21 has an upper negative contact 211 at its top and a lower positive contact 212 at its bottom. The upper negative contact 211 and the lower positive contact 212 are mutually insulated. For example, the horizontal pressing and fixing part 21 may have an embedded insulating material layer to electrically isolate the upper negative contact 211 from the lower positive contact 212. The pressure plate 14 has a negative electrode piece 192 at its bottom, which contacts the upper negative contact 211 and extends through the second protrusion 16 and the light source fixing plate 13 to connect with the negative electrode of the light source 12. The light source fixing plate 13 has a positive electrode piece 191 on its top surface, which contacts the lower positive contact 212 and extends through the light source fixing plate 13 to connect with the positive electrode of the light source 12.

[0035] The above-mentioned connection structure not only fixes the connecting rod to the lamp head, but also completes the wiring connection at the same time, making the wiring of the entire lamp simple.

[0036] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
