DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The utility model relates to an LED lamp, comprising a light-transmitting seat 100, a light source component and an electrical connector 400.

[0030] The light-transmitting seat 100 may be made of a light-transmitting plastic material. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the interior of the light-transmitting seat 100 defines a mounting cavity 110. In the direction shown in the figure, the light-transmitting seat 100 is placed vertically, the mounting cavity 110 is cylindrical, and at least the top of the mounting cavity 110 is open. A plurality of slots 120 are provided on the side wall of the mounting cavity 110, and each slot 120 is distributed along the circumference of the mounting cavity 110. The extension direction of the slots 120 is not limited, and can be vertically extended along the height direction of the light-transmitting seat 100, or can be obliquely extended, etc. The slots 120 can be set at a local position in the middle section of the side wall of the mounting cavity 110, or can be set to be consistent with the height of the light-transmitting seat 100, etc. The light-transmitting seat 100 is provided with a plurality of through slots 130, and the through slots 130 are located between two adjacent slots 120. In this embodiment, five slots 120 are provided on the side wall of the mounting cavity 110, and correspondingly, five through slots 130 are provided on the light-transmitting seat 100, and the through slots 130 connect the mounting cavity 110 to the outside of the light-transmitting seat 100. The light source component includes a driving mechanism 200 and a plurality of light bars 300. The light bar 300 can be configured as a plurality of LED lamp beads arranged on a long strip substrate. The light bars 300 are plugged into the slots 120 in pairs, and the slots 120 are used to quickly position and fix the light bars 300. The LED lamp beads on the light bar 300 can face the side wall of the installation cavity 110 where the through groove 130 is located, and the light is radiated outward through the light-transmitting seat 100. Each light bar 300 can be electrically connected to the driving mechanism 200 through a wire. The driving mechanism 200 can be installed in the installation cavity 110, and the driving mechanism 200 can be fixed in the installation cavity 110 by means of snap-on, bonding or screw locking. After installation, each light bar 300 is distributed around the driving mechanism 200. The electrical connector 400 is installed at the upper end opening of the installation cavity 110, and the electrical connector 400 is electrically connected to the live and neutral wires of the driving mechanism 200 through a wire or direct contact. The electrical connector 400 preferably uses an external threaded connector. When in use, part of the heat of the light bar 300 is transferred outward through the side wall of the light-transmitting seat 100 for heat dissipation, and part of the heat is dissipated in the installation cavity 110, and then diffused to the outside of the light-transmitting seat 100 through the through slot 130 for heat dissipation. The heat generated by the driving mechanism 200 is dissipated to the outside of the light-transmitting seat 100 through the through slot 130 in the installation cavity 110. Multiple through slots 130 enable convection in the installation cavity 110, thereby improving the overall heat dissipation effect; the light bar 300 is fixed by the slot 120, and is easy to position and install.

[0031] In some specific embodiments of the present invention, Figure 3 and Figure 4As shown, the two ends of the installation cavity 110 are respectively a first closed end 111 and a first open end 112. In the direction shown in the figure, the upper end of the installation cavity 110 is the first open end 112, and the lower end is the first closed end 111. The slot 120 extends vertically from the first open end 112 to the first closed end 111. The upper end of the slot 120 is close to the first open end 112, and the lower end of the slot 120 can extend to the end surface of the first closed end 111. The light bar 300 is inserted downward into the slot 120 from the first open end 112, and the lower end of the light bar 300 can abut against the end surface of the first closed end 111, thereby limiting the installation depth and position of the light bar 300. The driving mechanism 200 is installed at a position close to the first open end 112 to facilitate the connection between the driving mechanism 200 and the electrical connector 400.

[0032] Specifically, Figure 3 and Figure 4 As shown, a plurality of circumferentially distributed clips 121 are provided on the side wall of the mounting cavity 110. The cross section of the clip 121 is L-shaped, and the cross section direction of the clip 121 is the top view direction from the first open end 112 to the first closed end 111. Every two adjacent clips 121 form a group, and a slot 120 is defined between the two clips 121 in the same group. The light bar 300 is inserted into the slot 120, and the clips 121 are clipped on both sides of the light bar 300. The substrate of the light bar 300 can be exposed in the mounting cavity 110 from the spacing between the two clips 121, ensuring the heat dissipation effect of the substrate of the light bar 300 to the mounting cavity 110.

[0033] In some specific embodiments of the present invention, Figure 2 and Figure 5 As shown, the driving mechanism 200 includes a connecting seat 210 and a circuit board 220. The circuit board 220 is mounted on the connecting seat 210. The circuit board 220 is electrically connected to the light bar 300. The connecting seat 210 is provided with a convex edge 211 extending in the circumferential direction. The connecting seat 210 is placed in the installation cavity 110, and the convex edge 211 overlaps one end of each slot 120 close to the first opening end 112. That is, during installation, the light bar 300 is inserted into the slot 120, and then the connecting seat 210 is placed into the installation cavity 110 from the first opening end 112. The distribution positions of each slot 120 surround the connecting seat 210, and the convex edge 211 of the connecting seat 210 overlaps the upper end of each slot 120. On the one hand, the upper end of the slot 120 can be blocked by the convex edge 211 to prevent the light bar 300 from sliding out, and on the other hand, the connecting seat 210 is installed in this way. The connection base 210 can further fix the protruding edge 211 and the end of the slot 120 by bonding, or the connection base 210 can be crimped onto the end of the slot 120 by the electrical connector 400 or other components for fixation.

[0034] Furthermore, a plurality of columns 212 are provided on the flange 211. Figure 5 As shown, the column 212 extends vertically upward from the convex edge 211, and the column 212 can be in the shape of a plate, a cylinder, etc. The circuit board 220 is overlapped on each column 212. A pressure seat (500) is installed on the first open end 214, and the pressure seat (500) can be connected to the first open end 214 by means of threaded connection, buckle connection, etc. The pressure seat (500) is hollow, and the electrical connector 400 is installed on the pressure seat (500), and the two can be connected by means of sleeve connection, bonding, etc. The pressure seat (500) is crimped on the periphery of the circuit board 220, so that the circuit board 220 is clamped between the pressure seat (500) and the column 212 for fixation. The wires of the circuit board 220 can pass through the pressure seat (500) and connect to the electrical connector 400.

[0035] Further, such as Figure 5 As shown, the connection base 210 is a hollow cylindrical structure. The lower end of the connection base 210 is a second closed end 213, and the upper end is a second open end 214. The flange 211 is arranged on the periphery of the second open end 214, and the flange 211 protrudes radially along the connection base 210. The connection base 210 is installed in the installation cavity 110, and the second open end 214 (upward) faces the electrical connector 400. The second closed end 213 faces the first closed end 111. The circuit board 220 is installed on the second open end 214. The electrical modules such as capacitors on the circuit board 220 extend into the connection base 210. A plurality of fine holes 215 are provided on the end surface of the second closed end 213. The fine holes 215 can connect the interior of the connection base 210 with the installation cavity 110 to increase the heat dissipation effect. The aperture of the fine holes 215 can be set to a size that can limit the passage of mosquitoes to prevent mosquitoes from drilling into the connection base 210.

[0036] In some specific embodiments of the present invention, Figure 2 As shown, a plurality of light bars 300 are fixed on a connecting plate 310. The connecting plate 310 extends along the distribution direction of each slot 120. The distribution positions of each light bar 300 on the connecting plate 310 are set according to the distribution positions of the slots 120. Each light bar 300 can be aligned with each slot 120 one by one at the same time, and each light bar 300 can be inserted into the slot 120 at the same time by pushing the connecting plate 310. When the light bar 300 is inserted into the corresponding slot 120, the connecting plate 310 abuts against the outer side of the upper end of the slot 120, thereby also being able to position the insertion depth of the light bar 300 relative to the slot 120.

[0037] Further, such as Figure 2 and Figure 6 As shown, a plug hole (221) is provided on the circuit board (220). A connecting plate 310 protrudes upward from the upper end of one of the light bars (300), and the upper end of the light bar 300 is plugged into the plug hole (221). In this way, the circuit board 220 and the light bar 300 are positioned to facilitate wiring or conductive welding.

[0038] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the first closed end 111 is provided with a hollow structure 140, which can be a through hole, etc. The bottom of the mounting cavity 110 is connected to the bottom of the light-transmitting seat 100 through the hollow structure 140. On the one hand, the convection heat dissipation effect is increased, and on the other hand, the hollow structure 140 can be set as a through hole with a texture shape, and a part of the light passes through the hollow structure 140 to form a light effect.
