Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp that is easy to assemble. Background Art

[0002] In recent years, due to the rapid development of the LED industry, LED bulbs have gradually replaced traditional lighting fixtures. In addition, LED bulbs, as a cold light source, have been widely used in life.

[0003] Application publication number CN107461617A discloses an LED filament, specifically comprising a substrate and multiple LED light sources. The substrate is made of a thermally conductive material, and the LED light sources are spaced apart and thermally connected to the substrate. The substrate integrally includes a heat transfer portion, which is used to thermally connect to an external heat sink to transfer heat generated by the LED light sources on the substrate. The arrangement density of the LED light sources on the heat transfer portion is greater than the arrangement density of the LED light sources on the portion of the substrate outside the heat transfer portion. The filament also includes an encapsulation layer that covers all the LED light sources on the substrate. It also includes electrode terminals, which are disposed at either end or one end of the substrate and are used to electrically connect the LED light sources to an external driving power source.

[0004] However, the aforementioned LED filaments still present some challenges. For example, in actual use, the electrode terminals on the substrate typically require conductive wires to electrically connect the LED light source to an external driver power source. Currently, these conductive wires are typically assembled to the electrode terminals using welding, a complex manufacturing process that can reduce assembly efficiency. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an LED lamp that is easy to assemble, which can enable the two conductive parts to be contacted and connected with the two conductive wires respectively, so that the conductive wires can be connected to the two conductive parts conveniently and quickly, and the step of welding between the conductive parts and the conductive wires is eliminated, thereby improving the assembly efficiency.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] An LED lamp that is easy to assemble, comprising a lampshade, an LED filament, a lamp holder and a positioning seat; the LED filament comprises a substrate, an LED light source, an encapsulation layer, two conductive parts, a first conductive filament and a second conductive filament; the LED light source is arranged on the upper end of the surface of the substrate, and the two surfaces of the upper end of the substrate are encapsulated with an encapsulation layer and the encapsulation layer covers the LED light source; the two conductive parts are respectively arranged on one surface of the substrate and extend downward, and the two conductive parts are used to be electrically connected to the LED light source respectively; the positioning seat is installed in the opening at the lower end of the lampshade; a There are positioning holes running through the upper and lower parts; the lower ends of the first conductive wire and the second conductive wire respectively pass through the positioning holes downward, and the upper ends are respectively clamped on the positioning seats; the lower end of the substrate is matched and inserted into the positioning hole and makes the two conductive parts contact the first conductive wire and the second conductive wire respectively to achieve electrical connection; the contact connection method between the conductive part and the first conductive wire and the second conductive wire can facilitate the assembly of the LED filament to improve assembly efficiency; the lamp head is sleeved on the outside of the opening at the lower end of the lampshade and is correspondingly connected to the lower ends of the first conductive wire and the second conductive wire respectively.

[0008] The following technical solutions are also included:

[0009] Furthermore, two slots are provided on the upper end of the positioning seat for respectively clamping the upper end of the first conductive thread and the upper end of the second conductive thread, thereby achieving the effect of positioning the first conductive thread and the second conductive thread.

[0010] Furthermore, two latching slots are respectively provided on the top surface of the positioning seat, and each of the latching slots extends outward from the side of the positioning hole; the upper ends of the first conductive thread and the upper ends of the second conductive thread are respectively curved downward, so that the upper ends of the first conductive thread and the upper ends of the second conductive thread can be respectively hooked and fastened in the two latching slots. This arrangement facilitates and stably positions the first conductive thread and the second conductive thread.

[0011] Furthermore, it also includes a resistor and a rectifier bridge; the resistor is connected to one of the conductive parts; and the rectifier bridge is connected to two of the conductive parts respectively.

[0012] Furthermore, the rectifier bridge is closer to the lamp holder than the resistor.

[0013] Furthermore, a covering layer is included; the resistor and the rectifier bridge are respectively located in the middle of the substrate; the covering layer is formed around the middle of the substrate by injection molding, and the covering layer covers the resistor and the rectifier bridge. This arrangement can cover the resistor and the rectifier bridge, thus achieving a hidden design, thereby preventing the resistor and the rectifier bridge from being visible outside the lampshade, thereby improving the aesthetics of the LED filament.

[0014] Furthermore, the lower end of the substrate can be clamped in the positioning hole with an interference fit, so that the substrate can be assembled on the positioning seat conveniently and quickly.

[0015] Furthermore, a plurality of evenly distributed anti-slip convex strips are provided on the outer surface of the positioning seat so that the positioning seat can be installed in the opening at the lower end of the lampshade with an interference fit.

[0016] Furthermore, the outer surface of the encapsulation layer is in an arc shape, so that the light can be distributed more evenly.

[0017] Furthermore, the encapsulation layer includes a phosphor material, which emits light uniformly when excited by the light emitted by the LED light source.

[0018] The beneficial effects of the utility model are:

[0019] (1) In the present invention, since the lower end of the substrate can be used to match and be inserted into the positioning hole and the two conductive parts can be respectively contacted and connected with the upper ends of the first conductive wire and the second conductive wire, the first conductive wire and the second conductive wire can be connected on the two conductive parts conveniently and quickly. The assembly process is simple and the step of welding between the conductive parts and the conductive wires is eliminated, thereby greatly improving the assembly efficiency.

[0020] (2) Since the utility model has a covering layer for covering the resistor and the rectifier bridge on the substrate, the resistor and the rectifier bridge can be hidden in appearance without affecting the normal use of the resistor and the rectifier bridge, thereby improving the aesthetics of the lamp.

[0021] (3) In the present invention, since the substrate of the LED filament is detachably mounted on the positioning hole of the positioning seat, the LED filament or the positioning seat can be replaced separately when damaged without affecting other components; moreover, if it is necessary to replace a lampshade with an opening of a different size, it is only necessary to directly and synchronously replace the positioning seat with a different outer diameter. However, the size and position of the positioning hole and the card slot on each positioning seat need to remain unchanged, that is, the LED filament does not need to be replaced at this time, so that the unreplaced LED filament can continue to be used on the new positioning seat. This design can reduce the replacement cost and use cost of the lamp to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following describes in detail the specific implementation methods according to the present disclosure in conjunction with the accompanying drawings.

[0037] like Figures 1-6 As shown, an LED lamp that is easy to assemble includes a lampshade 1, an LED filament 2, a lamp holder 3 and a positioning seat 4.

[0038] The LED filament 2 includes a substrate 21 , an LED light source (not shown), a packaging layer 22 , two conductive parts 23 , a first conductive filament 24 and a second conductive filament 25 .

[0039] The following is a detailed description of the settings of each component:

[0040] The LED light source is disposed at the upper ends of both surfaces of the substrate 21. Both surfaces of the upper end of the substrate 21 are encapsulated with an encapsulation layer 22, and the encapsulation layer 22 covers the LED light source. Specifically, the outer surface of the encapsulation layer 22 is arc-shaped, thereby enabling a more uniform light distribution. In addition, the encapsulation layer 22 includes a phosphor material, which emits light uniformly when excited by the light emitted by the LED light source. Since the structures between the substrate 21, the LED light source, and the encapsulation layer 22 are all prior art, they will not be described in detail here.

[0041] The substrate 21 is transparent.

[0042] like Figure 2-Figure 6 As shown, the two conductive parts 23 are respectively provided on a surface of the substrate 21 and extend downwards. At the same time, the two conductive parts 23 are used to be electrically connected to the LED light sources respectively.

[0043] like Figure 2-Figure 6 As shown, the positioning seat 4 is installed in the opening 11 at the lower end of the lampshade 1, so that the positioning seat 4 can be easily positioned; a positioning hole 41 is also provided in the middle of the positioning seat 4 and passes through it from top to bottom.

[0044] In addition, the lampshade 1 is made of transparent plastic.

[0045] like Figure 2-Figure 6 As shown, the lower ends of the first conductive wire 24 and the second conductive wire 25 respectively pass through the positioning holes 41 downward, and the upper ends are respectively clamped on the positioning seat 4, so that the first conductive wire 24 and the second conductive wire 25 can be positioned respectively.

[0046] like Figure 2-Figure 6 As shown, the lower end of the substrate 21 is matched and inserted into the positioning hole 41 and the two conductive parts 23 are respectively in contact with the first conductive wire 24 and the second conductive wire 25, so that electrical connection can be achieved, and one of the conductive wires serves as the positive electrode and the other as the negative electrode. Therefore, by setting the connection mode between the conductive part 23 and the first conductive wire 24 and the second conductive wire 25 to a contact connection, the first conductive wire 24 and the second conductive wire 25 can be easily assembled to improve assembly efficiency. Specifically, the lower end of the substrate 21 can be inserted into the positioning hole 41 with an interference fit, that is, the substrate 21 is detachably mounted in the positioning hole 41, which can also facilitate the assembly of the substrate 21.

[0047] like Figure 2-Figure 6 As shown, the lamp holder 3 is sleeved outside the opening 11 at the lower end of the lampshade 1 and is respectively connected to the lower ends of the first conductive wire 24 and the second conductive wire 25. Since the connection structure between the conductive wire and the lamp holder 3 is prior art, it will not be described in detail here.

[0048] Specifically, the lamp holder 3 and the lampshade 1 are connected by threaded connection, so that the lamp holder 3 can be easily disassembled and assembled.

[0049] like Figure 3-Figure 6 As shown, in order to facilitate the assembly of the positioning seat 4, a plurality of evenly distributed anti-slip ridges 43 are provided on the outer surface of the positioning seat 4 so that the positioning seat 4 can be installed in the opening 11 at the lower end of the lampshade 1 with an interference fit.

[0050] like Figure 3-Figure 6 As shown, specifically, two clamping grooves 42 for clamping the upper ends of the first conductive wire 24 and the second conductive wire 25 are provided at the upper end of the positioning seat 4 .

[0051] like Figure 3-Figure 6 As shown, more specifically, two locking grooves 42 are respectively provided on the top surface of the positioning seat 4, and each locking groove 42 extends outward from the side of the positioning hole 41; the upper end of the first conductive wire 24 and the upper end of the second conductive wire 25 are respectively bent downward, so that the upper end of the first conductive wire 24 and the upper end of the second conductive wire 25 can be respectively hooked in the two locking grooves 42. Preferably, the upper end of the first conductive wire 24 and the upper end of the second conductive wire 25 are respectively bent in an arc shape.

[0052] like Figure 3-Figure 6 As shown, the present invention further includes a resistor 5 and a rectifier bridge 6; the resistor 5 is connected to one conductive portion 23; and the rectifier bridge 6 is respectively connected to two conductive portions 23. As the arrangement of the resistor 5 and the rectifier bridge 6 also belongs to the prior art, they will not be described in detail here.

[0053] Among them, the position of the rectifier bridge 6 is closer to the lamp holder 3 than the resistor 5. Figure 3 , that is, the rectifier bridge 6 is located below the resistor 5.

[0054] like Figure 6 As shown, in this embodiment, the utility model further includes a covering layer 7; in addition, the resistor 5 and the rectifier bridge 6 are respectively located in the middle of the substrate 21; the covering layer 7 is formed around the middle of the substrate 21 by injection molding, and the covering layer 7 covers the resistor 5 and the rectifier bridge 6, so that the resistor 5 and the rectifier bridge 6 can be hidden by using the covering layer 7, that is, a hidden design is realized to avoid observing the resistor 5 and the rectifier bridge 6 outside the lampshade 1, thereby improving the aesthetics of the LED filament 2.

[0055] In addition, the surface of the covering layer 7 is flat. This arrangement allows people to print logos or other logos and patterns on the surface of the covering layer 7 for promotion or to improve the aesthetics.

[0056] Of course, the covering layer 7 needs to be made of insulating material.

[0057] In summary, the present invention allows for quick and easy connection of the first and second conductive wires 24, 25 to the two conductive portions 23, as the lower end of the substrate 21 can be inserted into the positioning hole 41 and the two conductive portions 23 can be brought into contact with the upper ends of the first and second conductive wires 24, 25, respectively. This simplifies the assembly process and eliminates the need for soldering between the conductive portions 23 and the conductive wires, significantly improving assembly efficiency. Furthermore, the substrate 21 is provided with a covering layer 7 for covering the resistor 5 and the rectifier bridge 6, thereby effectively concealing the resistor 5 and the rectifier bridge 6 without affecting their normal operation, thereby enhancing the aesthetics of the lamp. At the same time, since the substrate 21 of the LED filament 2 is detachably mounted on the positioning hole 41 of the positioning seat 4, the LED filament 2 or the positioning seat 4 can be replaced separately when damaged without affecting other components; moreover, if it is necessary to replace the lampshade 1 with an opening 11 of a different size, it is only necessary to directly and synchronously replace the positioning seat 4 of a different outer diameter, but the size and position of the positioning hole 41 and the card slot 42 on each positioning seat 4 need to remain unchanged, that is, the LED filament 2 does not need to be replaced at this time, so that the unreplaced LED filament 2 can continue to be used on the new positioning seat 4. This design can reduce the replacement cost and use cost of the lamp to a certain extent.

[0058] The scope of the present disclosure is not defined by the above-described embodiments but by the appended claims and their equivalents.
