Description

Technical Field

[0001] The invention relates to the technical field of LED lamps, and in particular to an improved new type of LED lamp. 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 CN110425434A discloses a plastic LED filament bulb and a production method thereof, wherein the plastic LED filament bulb specifically discloses a lampshade, a lamp holder and a plastic wick, wherein a plug-in section is provided at the lower end of the lampshade, and the plastic wick comprises an injection-molded rubber plug adapted to the inner diameter of the plug-in section, a first conductive wire, a second conductive wire with a resistance driving element and an LED filament, wherein the two ends of the LED filament are respectively welded and fixed to the upper ends of the first conductive wire and the second conductive wire, the middle part of the first conductive wire and the resistance driving element of the second conductive wire are automatically braided and injection-molded to form a plastic wick body, and the plastic wick is fixed in the lampshade by inserting the injection-molded rubber plug into the plug-in section by interference fit.

[0004] However, there are still some problems with the above-mentioned LED filaments. For example, although the middle part of the first conductive filament and the resistance driving element of the second conductive filament are both injection-molded as injection-molded rubber plugs, a portion of the first conductive filament and the second conductive filament between the top of the injection-molded rubber plug and the LED filament is still exposed, so that the exposed conductive filament at this position is easily bent and deformed due to vibration or gravity during the transportation of the light bulb, which in turn affects the normal use of the light bulb. That is, the anti-deformation property of the conductive filament is not good enough. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide an improved new type of LED lamp, in which the injection molded plug can completely cover the middle and upper ends of the conductive wire. This design can not only ensure the stability of the conductive wire wrapped by the injection molded plug and prevent its deformation and bending, but also facilitate its use and transportation, etc.; the upper end of the injection molded plug can also be used to print corresponding patterns or logos for promotion or to improve the aesthetics.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] An improved new type of LED lamp, comprising a lampshade, an LED filament, a lamp holder and a positioning seat; the LED filament comprises a substrate, an LED light source, a packaging layer, two conductive parts, two conductive wires and an injection-molded rubber plug; the LED light source is arranged on the surface of the substrate, and the packaging layer covering the LED light source is packaged on both surfaces of the substrate; the two conductive parts are respectively arranged at the lower end of one surface of the substrate and are respectively electrically connected to the LED light source; the upper ends of the two conductive wires are respectively connected to the two conductive parts; the middle parts and upper ends of the two conductive wires and the substrate and the lower ends of the two conductive parts are all formed by injection molding of the injection-molded rubber plug. The lampshade is covered by a plug, and the injection molded plug extends upward to a position close to the bottom of the packaging layer, so that the middle and upper ends of the two conductive wires are not easy to bend and deform and their stability is improved. At the same time, the injection molded plug can be used to prevent electric shock and its upper end surface can be used to print patterns or logos; the positioning seat is installed in the opening at the lower end of the lampshade; a positioning hole penetrating up and down is provided in the middle of the positioning seat; the lower end of the injection molded plug can be matched and clamped in the positioning hole to position the LED filament; the lower ends of the two conductive wires respectively pass through the positioning holes downward; the lamp head is sleeved outside the opening at the lower end of the lampshade and is respectively connected to the lower ends of the two conductive wires.

[0008] The following technical solutions are also included:

[0009] Furthermore, the lower end of the injection-molded rubber plug is interference-fitted with the positioning hole, thereby facilitating assembly of the injection-molded rubber plug and improving assembly efficiency.

[0010] Furthermore, the injection molded plug includes a printing portion located at the top and a positioning portion located at the bottom; the printing portion and the positioning portion are both flat and the thickness of the positioning portion is greater than the thickness of the printing portion; the positioning portion can be used for interference fit with the positioning hole, and the outer surface of the printing portion can be used for printing patterns or logos.

[0011] Furthermore, the surrounding outer surfaces of the positioning portion and the surrounding side surfaces of the positioning hole are two planes and two arc-shaped surfaces connected in sequence at intervals, so that the connection between the positioning portion and the positioning hole can be very stable.

[0012] Furthermore, the positioning seat includes a central portion located in the middle and having the positioning hole in the center, a plurality of support bars radially connected to the outer sides of the central portion, and baffles respectively connected to the outer ends of the plurality of support bars; a heat dissipation hole penetrating from top to bottom is formed between two adjacent support bars. The above arrangement enables the positioning seat to use the central portion to be connected to the injection molding plug, and the arrangement of the heat dissipation hole can improve the heat dissipation efficiency of the LED filament, thereby extending the service life of the LED filament to a certain extent.

[0013] Furthermore, a first protrusion is extended outwardly around the bottom of the baffle plate to match the bottom surface of the lampshade; when the positioning seat is matched and installed in the opening at the lower end of the lampshade, the first protrusion is attached to the bottom surface of the lampshade. The above arrangement enables the positioning seat to be limited by the first protrusion during the installation process to prevent the positioning seat from exceeding the preset stroke.

[0014] Furthermore, a second protrusion is extended outwardly around the bottom of the positioning portion to match the bottom surface of the central portion; when the lower end of the injection rubber plug is matched and clamped in the positioning hole, the second protrusion is attached to the bottom surface of the positioning portion. The above arrangement allows the injection rubber plug to be limited by the second protrusion during installation to prevent the injection rubber plug from exceeding a preset stroke.

[0015] Furthermore, a plurality of evenly distributed anti-slip convex strips are arranged on the outer sides of the positioning seat so that the positioning seat can be installed in the opening at the lower end of the lampshade with interference fit. The above arrangement can ensure the connection stability between the positioning seat and the lampshade.

[0016] Furthermore, external threads are arranged around the opening around the lower end of the lampshade, and internal threads corresponding to the external threads are arranged in the lamp holder, so that the lamp holder and the lampshade can be threadedly connected.

[0017] Furthermore, a resistor is included; the resistor is connected to one of the conductive threads and is covered by the injection-molded rubber plug.

[0018] The beneficial effects of the present invention are:

[0019] (1) The present invention extends the injection molded plug upward to a position close to the bottom of the packaging layer, so that the middle and upper ends of the conductive wires can be completely covered. That is, the conductive wires will not be exposed above the injection molded plug as in the prior art. This design can not only ensure the stability of the conductive wires covered by the injection molded plug and prevent them from deformation and bending, but also facilitate use and transportation. Moreover, the upper end of the injection molded plug can also be used to print corresponding patterns, such as logos or other logos, etc., for promotion or to improve aesthetics. Of course, the injection molded plug also has the function of preventing people from electric shock.

[0020] (2) In the present invention, since the injection-molded rubber plug 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 openings of different sizes, it is only necessary to directly and synchronously replace the positioning seats with different outer diameters, but the size of the positioning hole on each positioning seat needs 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

[0032] The specific implementation methods according to the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 6As shown, an improved new type of LED lamp includes a lampshade 1, an LED filament 2, a lamp holder 3 and a positioning seat 4.

[0034] like Figure 2-Figure 6 As shown, the LED filament 2 includes a substrate 21, an LED light source (not shown in the figure), a packaging layer 22, two conductive parts (not shown in the figure), two conductive wires 23 and an injection-molded rubber plug 24; the LED light source is arranged on the surface of the substrate 21, and the two surfaces of the substrate 21 are both encapsulated with the packaging layer 22 covering the LED light source; the two conductive parts are respectively arranged at the lower end of one surface of the substrate 21 and are respectively electrically connected to the LED light source; the upper ends of the two conductive wires 23 are respectively connected to the two conductive parts, specifically by welding. Therefore, the arrangement of the conductive part can realize electrical connection between the conductive wire 23 and the LED light source.

[0035] like Figure 2-Figure 5 As shown, for the two conductive threads 23, the middle parts and upper ends of the two conductive threads 23 and the lower ends of the substrate 21 and the two conductive parts are all covered by injection-molded rubber plugs 24, and the injection-molded rubber plugs 24 extend upward to a position close to the bottom of the encapsulation layer 22, so that the middle parts and upper ends of the two conductive threads 23 are not easy to bend and deform and their stability is improved. At the same time, the injection-molded rubber plugs 24 can be used to prevent electric shock and the upper end surface thereof can be used for printing patterns or logos.

[0036] like Figure 2-Figure 5 As shown, the positioning seat 4 is installed in the opening 11 at the lower end of the lampshade 1; in addition, a positioning hole 411 is provided in the middle of the positioning seat 4 and passes through the positioning hole 411; the lower end of the injection-molded rubber plug 24 can be matched and clamped in the positioning hole 411 to position the LED filament 2 to prevent it from loosening; the lower ends of the two conductive wires 23 respectively pass through the positioning holes 411 downward.

[0037] like Figure 2-Figure 5 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 two conductive wires 23. Therefore, by electrically connecting the lamp holder 3 to an external power source, the two conductive wires 23 and the conductive part can be used to power the LED light source. Since the connection structure between the lamp holder 3 and the two conductive wires 23 is a prior art, it will not be described in detail here.

[0038] like Figure 2-Figure 5 As shown, in this embodiment, the lower end of the injection rubber plug 24 is interference fit with the positioning hole 411, so that the injection rubber plug 24 can be easily assembled, the assembly efficiency can be improved, and of course, it can also be easily disassembled.

[0039] like Figure 2-Figure 5As shown, in this embodiment, the injection molded plug 24 includes a printing portion 241 located at the top and a positioning portion 242 located at the bottom; moreover, the printing portion 241 and the positioning portion 242 are both flat and the thickness of the positioning portion 242 is greater than the thickness of the printing portion 241; the positioning portion 242 can be used for interference fit with the positioning hole 411, and the outer surface of the printing portion 241 can be used for printing patterns or logos.

[0040] In this embodiment, the injection-molded rubber plug 24 is made of insulating material.

[0041] like Figure 2-Figure 5 As shown, in this embodiment, the surrounding outer surfaces of the positioning portion 242 and the surrounding side surfaces of the positioning hole 411 are two planes and two arc-shaped surfaces connected in sequence at intervals, so that the connection between the positioning portion 242 and the positioning hole 411 can be very stable, and the positioning portion 242 is not easy to rotate in the positioning hole 411.

[0042] like Figure 2-Figure 5 As shown, in this embodiment, the positioning seat 4 includes a central portion 41 located in the middle and having a positioning hole 411 in the center, a plurality of support bars 42 radially connected to the outer sides of the central portion 41, and a baffle 43 connected to the outer ends of the plurality of support bars 42; a heat dissipation hole 44 penetrating from top to bottom is formed between two adjacent support bars 42. Therefore, through the above arrangement, the positioning seat 4 can use the central portion 41 to connect with the injection molding plug 24, and the arrangement of the heat dissipation hole 44 can improve the heat dissipation efficiency of the LED filament 2, thereby extending the service life of the LED filament 2 to a certain extent.

[0043] like Figure 2-Figure 5 As shown, in this embodiment, first protrusions 45 for matching with the bottom surface of the lampshade 1 are extended outwardly around the bottom of the baffle 43; when the positioning seat 4 is matched and installed in the opening 11 at the lower end of the lampshade 1, the first protrusions 45 are attached to the bottom surface of the lampshade 1. Therefore, after the first protrusions 45 are provided, the positioning seat 4 can be limited by the first protrusions 45 during the installation process to prevent the positioning seat 4 from exceeding the preset stroke. For example, when the positioning seat 4 is pushed upward in the opening 11, the positioning seat 4 is installed in place until the first protrusions 45 abut against the bottom surface of the lampshade 1.

[0044] like Figure 2-Figure 5As shown, in this embodiment, a second protrusion 243 for matching with the bottom surface of the center portion 41 extends outward around the bottom of the positioning portion 242; when the lower end of the injection rubber plug 24 is matched and clamped in the positioning hole 411, the second protrusion 243 is attached to the bottom surface of the positioning portion 242. Similarly, by setting the second protrusion 243, the injection rubber plug 24 can be limited by the second protrusion 243 during the installation process to prevent the injection rubber plug 24 from exceeding the preset stroke. For example, when the injection rubber plug 24 is pushed upward in the positioning hole 411, the injection rubber plug 24 is installed in place until the second protrusion 243 abuts against the bottom surface of the positioning portion 242.

[0045] like Figure 2-Figure 5 As shown, in this embodiment, a plurality of evenly distributed anti-skid convex strips 46 are provided on the outer sides 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 interference fit. Specifically, the anti-skid convex strips 46 are provided on the outer sides of the baffle 43. Therefore, by providing the anti-skid convex strips 46, the connection stability between the positioning seat 4 and the lampshade 1 can be ensured.

[0046] like Figure 2-Figure 5 As shown, in the present embodiment, external threads 12 are arranged around the opening 11 on all sides of the lower end of the lampshade 1, and internal threads 31 corresponding to the external threads 12 are arranged in the lamp holder 3, so that a threaded connection can be achieved between the lamp holder 3 and the lampshade 1, thereby facilitating the disassembly and assembly of the lamp holder 3.

[0047] The present invention also includes a resistor (not shown); the resistor is connected to a conductive wire 23 and covered by an injection-molded rubber plug 24. In this embodiment, the resistor is located in the positioning portion 242. Since the arrangement of the resistor on the conductive wire 23 is a prior art, it will not be described in detail here.

[0048] In this embodiment, the packaging layer 22 includes a phosphor material, which emits light evenly when excited by the light emitted by the LED light source. In addition, the surface of the packaging layer 22 is curved, so that the light can be dispersed more evenly.

[0049] In this embodiment, the lampshade 1 is made of transparent plastic.

[0050] During assembly, first, the positioning seat 4 is correspondingly installed in the opening 11 of the lampshade 1 until the first protrusion 45 abuts against the bottom surface of the lampshade 1; next, the LED filament 2 with the injection-molded rubber plug 24 is upwardly inserted into the positioning hole 411 until the second protrusion 243 abuts against the bottom surface of the center portion 41; next, the lamp holder 3 is installed.

[0051] In summary, the present invention extends the injection plug 24 upward to a position close to the bottom of the packaging layer 22, so that the middle and upper ends of the conductive wire 23 can be completely covered, that is, the conductive wire 23 will not be exposed above the injection plug 24. This design can not only ensure the stability of the conductive wire 23 wrapped by the injection plug 24 and prevent its deformation and bending, but also facilitate use and transportation. Moreover, the upper end of the injection plug 24 can also be used to print corresponding patterns, such as logos or other logos, etc., for promotion or improvement of aesthetics. Of course, the injection plug 24 also has the function of preventing people from electric shock.

[0052] In addition, since the injection-molded rubber plug 24 of the LED filament 2 is detachably mounted on the positioning hole 411 of the positioning seat 4, the LED filament 2 or the positioning seat 4 can be replaced separately when damaged without affecting other components; and, if it is necessary to replace the lampshade 1 with openings 11 of different sizes, it is only necessary to directly and synchronously replace the positioning seats 4 of different outer diameters, but the size of the positioning hole 41 on each positioning seat 4 needs 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.
