Description

Technical Field

[0001] The invention relates to a lighting device, in particular to an LED bulb and a production process thereof. Background Art

[0002] As people's living standards improve, decorative lights have gradually become popular and can add to the festive atmosphere. In the past, light bulbs used tungsten filaments as light sources. With the advancement of technology, light sources have gradually been replaced by LEDs.

[0003] For example, the prior art CN213746184U discloses an LED glass Christmas light bulb, which uses an LED lamp as a light source, and specifically includes a plug-in LED lamp and a glass cover mounted outside the plug-in LED lamp, wherein the plug-in LED lamp and the glass cover are an integrated structure, the lamp beads of the plug-in LED lamp are located inside the glass cover, a light-transmitting space is provided between the lamp beads of the LED lamp and the inner cavity of the glass cover, and the pins of the plug-in LED lamp protrude outside the bottom end of the glass cover. The plug-in LED lamp includes a package body, a positive pin, a negative pin, an LED bracket and an LED chip all packaged in the package body, wherein the LED chip is welded to the LED bracket, and four groups of concave lenses and one group of plane lenses are arranged in the package body and above the LED bracket, wherein the four groups of concave lenses are separated around the plane lenses, and the four groups of concave lenses are placed on the four-equal lines of the plane lenses, and the edges thereof are tangent to the plane lenses and the inner wall of the package body, respectively, and the package body is located in a glass cover, wherein the positive pin and the negative pin are connected to the circuit of the LED bracket, and the positive pin and the negative pin both protrude out of the bottom end of the glass cover. In the above-mentioned prior art, the LED chip is welded to the LED bracket at the top of the negative pin and is supported by only one pin. In order to ensure the fixing reliability of the LED chip, the LED bracket needs to have a large enough area to place the LED chip, and the top volume appears to be large, which not only reduces the aesthetics, but also causes the size of the LED lamp beads to become larger, and the gap between the LED lamp beads and the inner hole wall of the glass cover to become smaller, which is not conducive to the LED lamp beads being installed in the glass cover. The LEDs of the prior art CN202695531U, CN205353994U, CN202613105U, and CN109713111A all adopt the above-mentioned fixing scheme, and the positive electrode of the LED is electrically connected to the positive pin through a wire, which not only increases the processing difficulty, but also has a large number of solder joints, and the reliability for long-term use is not high.

[0004] In order to overcome the above problems, the prior art CN220749961U, CN221348909U, CN109192837A, and CN212392260U all proposed to directly weld the LED lamp to the top of two pins. For example, CN221348909U discloses a light source device, including a transparent protective cover, an LED component, and a refractive lens. The transparent protective cover has a housing cavity with one end open; the LED component is arranged in the housing cavity, and the LED component is used to emit light; the refractive lens cover is arranged on or wrapped on the LED component, and the side of the refractive lens close to the LED component is the incident surface, and the side of the refractive lens away from the LED component is the emission surface, and the emission surface is used to refract the light passing through the emission surface. The LED component includes an LED chip, a first conductive column and a second conductive column, and the first conductive column and the second conductive column are arranged at intervals; the LED chip is electrically connected to the first conductive column and the second conductive column. The first conductive column and / or the second conductive column include a connecting portion and a conducting portion, the connecting portion and the conducting portion are connected in sequence; the connecting portion is located in the transparent protective cover, and the conducting portion extends out of the transparent protective cover; a carrier is provided at one end of the connecting portion away from the conducting portion; and the LED chip is bonded to the carrier. However, the same situation exists in the above-mentioned prior art. The pins are relatively thin, and the diameter is generally about 0.2mm. In order to ensure the contact area with the LED light-emitting body and improve the reliability of LED welding and fixing, the top of the pin needs to be widened, such as forming the above-mentioned carrier structure, but the effect of improving the reliability for long-term use is limited. Summary of the invention

[0005] The purpose of the present invention is to provide an LED bulb to solve the problem of low reliability of directly welding and fixing the LED light-emitting body to the top of the pin, improve the reliability of welding and fixing the LED light-emitting body to the pin, and greatly improve the reliability of long-term use of LED lamp beads.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an LED light bulb, comprising a glass lampshade and an LED lamp bead, the LED lamp bead is encapsulated in the glass lampshade, the LED lamp bead comprises a first pin, a second pin, an LED light-emitting body and a packaging body, the first pin and the second pin extend from the bottom end of the glass lampshade, the top end of the first pin is provided with a first bending section, the top end of the second pin is provided with a second bending section, the first bending section and the second bending section are basically located on a first plane to form an installation platform, the first plane is basically perpendicular to the axial direction of the glass lampshade, the first bending section and the second bending section are separated and bent toward each other, the LED light-emitting body is fixed to the installation platform and is respectively welded to the first bending section and the second bending section for electrical conduction, and the packaging body encapsulates the LED light-emitting body and the welding points between the LED light-emitting body and the first bending section and the second bending section.

[0007] After adopting the above technical scheme, the present invention has the following advantages: by bending the first pin and the second pin respectively to form the first bending section and the second bending section of sufficient length, the first bending section and the second bending section are basically on the first plane to form a mounting platform, and the LED light-emitting body can be stably supported before welding, which is not only convenient for positioning welding of the LED light-emitting body, but also conducive to the automated production of LED lamp beads, and because the contact length between the first bending section, the second bending section and the LED light-emitting body is large enough, the reliability of welding and fixing the LED light-emitting body with the first pin and the second pin can be improved, and the reliability of long-term use of the LED lamp beads can be greatly improved. The first bending section and the second bending section are basically on the first plane, which means that both can extend on the first plane, or can be tilted at a small angle relative to the first plane, so as to be able to position the LED light-emitting body flat, which is convenient for subsequent welding and fixing. Since the first plane is basically perpendicular to the axial direction of the glass lampshade, the light is emitted 360° along the circumference with the LED chip as the center, and the coverage range is close to the hemispherical area, and the light is uniform and the light effect is better under the same power. The first plane is substantially perpendicular to the axial direction of the glass lampshade, which means that the first plane can be perpendicular to the axial direction of the glass lampshade, or can be inclined at a small angle relative to the axial direction of the glass lampshade, so as to satisfy the 360° luminous effect toward the top as much as possible. The encapsulation body encapsulates the LED illuminator and the welding point between the LED illuminator and the first bending section and the second bending section, which can not only guide the light to be emitted evenly, but also further improve the reliability of the welding and fixing of the LED illuminator and the first pin and the second pin. The separation between the first bending section and the second bending section can obtain reliable electrical insulation performance. The first bending section and the second bending section are bent oppositely to form a symmetrical structure relative to the center of the LED illuminator. The stress generated after the LED illuminator is welded and fixed to the first bending section and the second bending section can offset each other for a large part after acting on the LED illuminator, so it is beneficial to further improve the long-term stability of the structure after the LED illuminator is welded and fixed, and it is beneficial to improve the service life of the LED lamp beads.

[0008] Furthermore, the LED bulb is a white light source, the LED light-emitting body is an LED that emits white light, the packaging body is a transparent and colorless packaging glue, and the glass lampshade is colorless glass.

[0009] Furthermore, the LED bulb is a color light source, the LED illuminant is a color-emitting LED, the encapsulation body is a transparent colorless encapsulation glue, and the glass lampshade is colorless glass;

[0010] Alternatively, the LED bulb is a colored light source, the LED illuminant is a white light emitting LED, the encapsulation body is a transparent colored encapsulation glue, and the glass lampshade is colorless glass;

[0011] Alternatively, the LED bulb is a colored light source, the LED light emitter is a white light emitting LED, the encapsulation body is a transparent colorless encapsulation glue, and the glass lampshade is colored glass.

[0012] The present invention also provides a production process of an LED bulb, which is used to produce the LED bulb of the above technical solution, including a production step of LED lamp beads and a packaging step of the LED lamp beads.

[0018] S150. Check the lighting of the LED lamp beads. If they light up, they are qualified products.

[0019] By adopting the above-mentioned technical scheme, the bending directions of the first bending section and the second bending section are opposite, so that the stress generated after the LED light-emitting body is welded and fixed to the first bending section and the second bending section can at least offset each other after acting on the LED light-emitting body, and the first bending section and the second bending section form a cantilever structure, which has a certain elastic support effect. The stress generated after the LED light-emitting body is welded and fixed to the first bending section and the second bending section can be directly absorbed and consumed by the first bending section and the second bending section after acting on the first bending section and the second bending section. Therefore, it is beneficial to improve the long-term stability of the structure after the LED light-emitting body is welded and fixed, and it is beneficial to improve the service life of the LED lamp beads. The packaging glue adopts UV glue, and the solidification speed can be accelerated by irradiation with ultraviolet light.

[0024] S102. Flatten the top ends of the first pin and the second pin to increase the contact area between the first bending section, the second bending section and the LED light-emitting body.

[0040] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] Embodiment 1: Figures 1 to 5As shown, the present invention provides an LED bulb, including a glass lampshade 500 and an LED lamp bead, the LED lamp bead is encapsulated in the glass lampshade 500, the LED lamp bead includes a first pin 100, a second pin 200, an LED light-emitting body 300 and a packaging body 400, the first pin 100 and the second pin 200 extend from the bottom end of the glass lampshade 500, the top end of the first pin 100 is provided with a first bending section 12, the top end of the second pin 200 is provided with a second bending section 22, the first bending section 12 and the second bending section 22 are basically located on a first plane M1 to form a mounting platform, the first plane M1 is basically perpendicular to the axial direction of the glass lampshade 500, the first bending section 12 and the second bending section 22 are separated and bent toward each other, the LED light-emitting body 300 is fixed on the mounting platform and is respectively welded to the first bending section 12 and the second bending section 22 for electrical conduction, and the packaging body 400 encapsulates the LED light-emitting body 300 and the welding points between the LED light-emitting body 300 and the first bending section 12 and the second bending section 22.

[0042] In order to simplify the description, the present invention uses the top, bottom and other directions to describe, which can be combined with Figures 1 to 3 To understand, the top of the picture is the top and the bottom is the bottom.

[0043] By bending the first pin 100 and the second pin 200 to form a first bending section 12 and a second bending section 22 of sufficient length, the first bending section 12 and the second bending section 22 are basically on the first plane to form a mounting platform, and the LED light-emitting body 300 can be stably supported before welding, which is not only convenient for positioning and welding of the LED light-emitting body 300, but also conducive to the automated production of LED lamp beads. Moreover, because the contact length between the first bending section 12, the second bending section 22 and the LED light-emitting body 300 is large enough, the reliability of welding and fixing the LED light-emitting body 300 with the first pin 100 and the second pin 200 can be improved, and the reliability of long-term use of the LED lamp beads can be greatly improved. The first bending section 12 and the second bending section 22 are basically on the first plane M1, which means that both can extend on the first plane M1, or can be inclined at a small angle relative to the first plane M1, so as to be able to position the LED light-emitting body 300 flat, which is convenient for subsequent welding and fixing.

[0044] Since the first plane is substantially perpendicular to the axial direction of the glass lampshade 500, the light is emitted 360° circumferentially with the LED chip as the center, and the coverage range is close to the hemispherical area, the light is uniform, and the lighting effect is better under the same power. The first plane M1 is substantially perpendicular to the axial direction of the glass lampshade 500, which means that the first plane M1 can be perpendicular to the axial direction of the glass lampshade 500, or can be inclined at a small angle relative to the axial direction of the glass lampshade 500, so as to meet the 360° lighting effect toward the top as much as possible.

[0045] The package body 400 packages the LED light emitting body 300 and the welding points between the LED light emitting body 300 and the first bending section 12 and the second bending section 22, which can not only guide the light to be emitted evenly, but also further improve the reliability of welding and fixing the LED light emitting body 300 and the first pin 100 and the second pin 200.

[0046] The separation of the first bending section 12 and the second bending section 22 can obtain reliable electrical insulation performance. The first bending section 12 and the second bending section 22 are bent toward each other to form a symmetrical structure relative to the center of the LED light-emitting body 300. The stress generated after the LED light-emitting body 300 is welded and fixed to the first bending section 12 and the second bending section 22 can largely offset each other after acting on the LED light-emitting body 300. Therefore, it is beneficial to further improve the long-term stability of the structure of the LED light-emitting body 300 after welding and fixing, and it is beneficial to improve the service life of the LED lamp beads.

[0047] The LED luminous body 300 may use a SMD LED, which generally includes an LED chip 31 and a substrate 32. The LED chip 31 and the substrate 32 are integrated into one body. The LED chip 31 is located on the front of the substrate 32. The back of the substrate 32 has a positive electrode welding surface 321 and a negative electrode welding surface 322. The positive electrode welding surface 321 and the negative electrode welding surface 322 are separated by an insulating gap 323. The first bending section 12 is welded and fixed to the positive electrode welding surface 321, and the second bending section 22 is welded and fixed to the negative electrode welding surface 322. The LED luminous body 300 may also use a non-polar LED, without distinguishing between positive and negative electrodes, and the two welding surfaces can be welded to the first bending section 12 and the second bending section 22 respectively.

[0048] The luminous color of the LED lamp beads can be customized according to customer needs. For example, the LED bulb can be a white light source, and the LED luminous body 300 is selected to be a white light LED, the encapsulation body 400 is a transparent and colorless encapsulation glue, and the glass lampshade 500 is a colorless glass. For another example, the LED bulb can be a colored light source, which can be realized in a variety of forms. One is that the LED luminous body 300 is a colored LED and the encapsulation body 400 is a transparent and colorless encapsulation glue, and the glass lampshade 500 is a colorless glass, that is, the LED luminous body 300 naturally emits colored light, the other is that the LED luminous body 300 is a white light LED and the encapsulation body 400 is a transparent and colored encapsulation glue, and the glass lampshade 500 is a colorless glass, that is, the encapsulation body 400 absorbs other color lights in the white light to achieve the corresponding color luminous effect, and another is that the LED luminous body 300 is a white light LED and the encapsulation body 400 is a transparent and colorless encapsulation glue, and the glass lampshade 500 is a colored glass, that is, the glass lampshade 500 absorbs other color lights in the white light to achieve the corresponding color luminous effect.

[0049] Embodiment 2: The present invention also provides a production process of an LED bulb, which is used to produce the LED bulb in the above embodiment. The structure of the LED bulb is referenced Figures 1 to 5 , including the production steps of LED lamp beads and the packaging steps of LED lamp beads, wherein the production steps of LED lamp beads include the following contents:

[0050] S100. Take a metal wire of a predetermined length to form a first pin 100 and a second pin 200;

[0051] S110. The top of the first pin 100 is bent to form a first bending section 12, and the top of the second pin 200 is bent to form a second bending section 22, and the bending directions of the first bending section 12 and the second bending section 22 are opposite, thereby forming a mounting platform;

[0052] S120. The LED light emitter 300 is placed on the mounting platform and welded to form a wick structure;

[0053] S130 inverts the wick structure so that the LED light emitting body 300 faces downward, and soaks the encapsulation glue so that the encapsulation glue wraps the LED light emitting body 300 and the LED light emitting body 300 and the first bending section 12, the second bending section 22 of the welding;

[0054] S140. The encapsulation glue solidifies into the encapsulation body 400, forming an LED lamp bead;

[0055] S150. Check the lighting of the LED lamp beads. If they light up, they are qualified products.

[0056] The first pin 100 and the second pin 200 are generally made of Dumet wire, because their thermal expansion coefficient is close to that of glass, so they are very suitable for products in which the glass lampshade 500 encapsulates LED lamp beads, and the length can be controlled at 20mm±2mm. The encapsulation glue can generally be made of common transparent colloids such as epoxy resin or UV glue, which have good moisture-proof and insulating properties. The bending directions of the first bending section 12 and the second bending section 22 are opposite, so that the stress generated after the LED illuminant 300 is welded and fixed with the first bending section 12 and the second bending section 22 can at least offset each other in part after acting on the LED illuminant 300, and the first bending section 12 and the second bending section 22 form a cantilever structure with a certain elastic support effect. The stress generated after the LED illuminant 300 is welded and fixed with the first bending section 12 and the second bending section 22 can be directly absorbed and consumed by the first bending section 12 and the second bending section 22 after acting on the first bending section 12 and the second bending section 22, so it is beneficial to improve the long-term stability of the structure after the LED illuminant 300 is welded and fixed, and it is beneficial to improve the service life of the LED lamp beads. The packaging glue adopts UV glue, and the solidification speed can be accelerated by irradiation with ultraviolet light. The S130 adopts an inverted wick structure to soak the packaging glue, so that the packaging body 400 can form a more uniform and smooth surface structure, and the light transmission effect is better.

[0057] In order to improve the flatness of the first bending section 12 and the second bending section 22 and the conductivity after welding with the LED light emitting body 300, S110 may also include the following content: when bending to form the first bending section 12 and the second bending section 22, scraping and cleaning the upper surface of the first bending section 12 and the second bending section 22. Since the bending and scraping and cleaning are completed simultaneously, no additional operation is required, and the efficiency is high.

[0058] Considering the continuity of automated production, in order to avoid the LED light emitter 300 from being emptied, the production steps of the LED lamp beads can be designed to also include the following additions between S100 and S110:

[0059] S101. Clamp the first pin 100 and the second pin 200 by the fixture and transport them to the inspection station to detect whether the first pin 100 and the second pin 200 are present on the fixture. If so, continue production; if not, suspend production. After adding S101, it can ensure that the first pin 100 and the second pin 200 are processed to form a mounting platform, thereby avoiding the LED light emitting body 300 from being empty and falling when it is placed on the mounting platform, which is conducive to saving production costs.

[0060] In order to increase the stability of the placement of the LED light emitting body 300, the production steps of the LED lamp beads may further include adding the following content after S101:

[0061] S102 . Flatten the top ends of the first pin 100 and the second pin 200 to increase the contact area between the first bending section 12 , the second bending section 22 and the LED light emitting body 300 .

[0062] The increase in contact area between the first bending section 12 , the second bending section 22 and the LED light emitting body 300 is beneficial to the pre-positioning of the LED light emitting body 300 and the reliability of subsequent welding.

[0063] Since the LED light-emitting body 300 is generally a rectangular structure, in order to facilitate automated assembly line operation, when the LED light-emitting body 300 is placed on the installation platform, the first bending section 12 and the second bending section 22 can be controlled to be basically parallel or perpendicular to the wide side of the LED light-emitting body 300 to ensure the contact length between the two, which is conducive to obtaining a reliable pre-positioning effect after the LED light-emitting body 300 is placed, thereby ensuring the reliability of subsequent welding. Therefore, S110 also includes the following content: when bending to form the first bending section 12 and the second bending section 22, the first pin 100 and the second pin 200 are formed, so that the first pin 100 forms a structure of the first base 11 and the first inclined section 13, and the second pin 200 forms a structure of the second base 21 and the second inclined section 23, and the first pin 100 forms a structure of the second base 21 and the second inclined section 23. An inclined section 13 is connected between the first substrate 11 and the first bending section 12, and a second inclined section 23 is connected between the second substrate 21 and the second bending section 22. The angles between the first inclined section 13 and the first bending section 12, and the angles between the second inclined section 23 and the second bending section 22 are both acute angles. During the processing, the fixture will clamp the first substrate 11 and the second substrate 21 at the same time, which is equivalent to controlling the first substrate 11 and the second substrate 21 to be parallel. On this basis, the first bending section 12 and the second bending section 22 can be bent in opposite directions perpendicular to the plane determined by the first substrate 11 and the second substrate 21, thereby ensuring that the first bending section 12 and the second bending section 22 can be basically parallel or perpendicular to the wide side of the LED light-emitting body 300, which is easy to maintain product consistency in assembly line production. In addition, the angle between the first inclined section 13 and the first bending section 12, and the angle between the second inclined section 23 and the second bending section 22 are both acute angles, which can make the first substrate 11 centered relative to the first bending section 12, and the second substrate 21 centered relative to the second bending section 22, so that the first substrate 11 and the second substrate 21 can be centered relative to the wide side of the LED light-emitting body 300, which can better support the LED light-emitting body 300. In addition, the spacing S between the first substrate 11 and the second substrate 21 can be reduced. When encapsulating the LED light-emitting body 300, the encapsulation glue flows along the first inclined section 13 and the second inclined section 23, and will adhere to each other and flow to the central area on the back of the LED light-emitting body 300, which can not only limit the encapsulation glue to flow a smaller distance along the first inclined section 13 and the second inclined section 23, but also make it more conducive for the encapsulation glue to cover the welding points between the LED light-emitting body 300 and the first bending section 12 and the second bending section 22, so as to obtain a better encapsulation effect.

[0064] In order to ensure that the relative positions of the first bending section 12 and the second bending section 22 meet the requirements for supporting the LED illuminant 300 before placing the LED illuminant 300, the production steps of the LED lamp beads may further include adding the following content between S110 and S120:

[0065] S111. Adjust the distance between the first bending section 12 and the second bending section 22 to meet the predetermined requirement.

[0066] This is beneficial to improving the supporting and positioning effect of the first pin 100 and the second pin 200 on the LED light emitting body 300 .

[0067] In one embodiment, in order to reliably weld and fix the LED illuminant 300, S120 may include the following contents:

[0068] S121. Add solder to the upper surface of the first bending section 12 and the upper surface of the second bending section 22;

[0069] S122. Place the LED light emitting body 300 from top to bottom flat on the first bending section 12 and the second bending section 22;

[0070] S123. Heat the solder of the first bending section 12 and the second bending section 22, and then cool them by blowing air, so as to fix the LED light source 300 by welding.

[0071] The solder can be in liquid form and attached to the first bending section 12 and the second bending section 22 by tension. After the LED illuminant 300 is placed, the LED illuminant 300 is adsorbed by tension, which can improve the pre-positioning effect of the LED illuminant 300 on the mounting platform. The solder of the first bending section 12 and the second bending section 22 can be heated by high-temperature hot air blowing without contact, which will not cause the position of the LED illuminant 300 relative to the first bending section 12 and the second bending section 22 to change during the welding process, and is also conducive to improving the long-term reliability of the LED illuminant 300 after welding.

[0072] In addition, the packaging steps of LED lamp beads include the following:

[0073] S200. Insert the qualified LED lamp bead into the glass lampshade 500, and ensure that the rear ends of the first pin 100 and the second pin 200 extend out of the glass lampshade 500;

[0074] S210. The rear end of the glass lampshade 500 is melted and fixed to the first pin 100 and the second pin 200 to form a whole, so that the rear end of the glass lampshade 500 is sealed;

[0075] S220. The glass lampshade 500 is hot-melted at a position between the LED lamp bead and the front end surface of the glass lampshade 500, and then the front end of the glass lampshade 500 is pulled away from the rear end, so that the hot-melted position of the glass lampshade 500 becomes thinner to form a stretching section, and the exhaust hole is retained in the stretching section;

[0076] S230. The gas in the glass lampshade 500 is extracted from the front end of the glass lampshade 500 through the exhaust hole, and then the stretching section is heat-melted to seal the exhaust hole, and the stretching section is disconnected to form an LED bulb.

[0077] The above production process can be completed by traditional manual operation, but the efficiency is low and quality control is difficult to grasp, so it can be achieved through automated machinery.

[0078] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
