Description

Technical Field

[0001] This invention relates to the field of light bulb technology, and more particularly to a high-efficiency, stable light bulb with a variable number of filaments. Background Technology

[0002] With the development of society, the use of light bulbs has also undergone different changes. Initially, it may have been to provide convenience for production and daily life, but with the progress of society, the use of light bulbs has also undergone obvious functional changes for different purposes.

[0003] Existing bulbs with flexible wicks mostly use ceramic as the wick material, resulting in high material costs and poor installation stability and sealing between the wick and bulb. Specifically, the fixing method between the wick and bulb in traditional bulbs is relatively simple, making them prone to loosening after long-term use; the sealing structure is mostly a single sealing ring, offering limited waterproof and dustproof performance. Regarding the string wires, existing string wires mostly use wire stripping and crimping for conductivity, a complex process with low production efficiency and high labor costs. Summary of the Invention

[0004] The purpose of this invention is to provide a highly efficient, stable light bulb with a variable number of wicks, in order to solve the aforementioned problems in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a high-efficiency, stable light bulb with a variable number of wicks, comprising a lamp holder, positive and negative leads, a soft rubber stopper, a soft wick, and a bulb shell. The soft wick includes a PCB board and a LED wafer. The PCB board is made of PET transparent film material and has several sets of LED wafers. The PCB board and the LED wafers are sealed with milky white soft silicone. An MCU wafer is disposed on the PCB board, and the LED wafer is electrically connected to the MCU wafer. The MCU wafer is electrically connected to the positive and negative leads through corresponding positive and negative lead pads. A wick lead adhesive is fixedly connected to the positive and negative leads. The wick lead adhesive passes through the soft rubber stopper and is fixed to the soft rubber stopper. The soft rubber stopper is sealed to the inner wall of the bulb shell, and a sealing ring on the soft rubber stopper is engaged with the end of the bulb shell. The lamp holder is screwed to the outside of the bulb shell, and the soft rubber stopper is located inside the lamp holder. The positive and negative leads are respectively connected to the positive and negative terminals of the lamp holder. The lamp holder is connected to a wire through a lamp base mechanism.

[0006] Furthermore, the lamp holder mechanism is a wireless lamp holder, which includes a connector, a lamp holder, positive and negative electrode springs, and a lamp holder bottom cover. Several connectors are connected to the wire at equal intervals. The lamp holder is disposed inside the connector. The wire is placed in the wire groove of the lamp holder. The positive and negative electrode springs are installed in the corresponding slots at the bottom of the lamp holder. The sharp ends of the positive and negative electrode springs protrude from the corresponding wire grooves. When the lamp holder bottom cover is pressed tightly by a machine, the positive and negative electrode springs pierce the wire insulation to contact the wire core inside the wire, thereby achieving conductivity.

[0007] Furthermore, the lamp holder mechanism is a lamp holder with a suspension wire. The lamp holder with a suspension wire includes several T-shaped seats, a suspension wire, a connector, positive and negative electrode springs, a lamp holder, and copper nails. Several T-shaped seats are connected to the wire at equal intervals. Each T-shaped seat is connected to a suspension wire. The suspension wire passes through the connector and is then fixed to the positive and negative electrode springs by press riveting. The positive and negative electrode springs are inserted into the corresponding slots of the lamp holder. The lamp holder is disposed inside the connector. The T-shaped seats have grooves for installing the wire and the suspension wire. The copper nails pierce the intersection points of the corresponding positions of the wire and the suspension wire to achieve conductivity.

[0008] Furthermore, the T-shaped base includes a front T-shaped frame and a rear T-shaped frame that are snapped onto the front and rear sides of the wire, and the front T-shaped frame and the rear T-shaped frame are connected and fixed by the copper nails.

[0009] Furthermore, the flexible wick may be provided with one, two, or three wicks.

[0010] Furthermore, one end of the wire is connected to a plug, and the other end is connected to a tail connector that plugs into another set of plugs.

[0011] Furthermore, the MCU wafer is a 2200K-6500K LED chip wafer or an RGB LED chip wafer.

[0012] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention provides a highly efficient, stable bulb with a variable number of wicks. The bulb uses a soft rubber plug to secure the soft wick, which is tightly fitted to the inner wall of the bulb shell. A sealing ring on the soft rubber plug engages with the bottom of the bulb shell, creating a double seal and positioning that ensures a secure and stable installation with high sealing reliability. Furthermore, the soft wick is made using a PCB board constructed from PET and PC transparent film materials, sealed with milky white soft silicone, reducing material costs. The bulb can be configured with single, double, or triple wicks, allowing for flexible selection of the required number. Simultaneously, the bulb holder is connected to the wire via a lamp base mechanism. For lamp bases without a suspension wire, a machine presses the base cover, causing the positive and negative electrode springs to pierce the wire insulation and contact the wire core for conductivity, eliminating the need for wire stripping and making it suitable for automated production. For lamp bases with a suspension wire, copper nails pierce the intersection of the wire and suspension wire to achieve conductivity. The copper nails simultaneously provide both fixation and conductivity, simplifying the production process, improving efficiency, and increasing the first-pass yield. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1 like Figures 1 to 7 As shown, the high-efficiency, stable bulb with a variable number of wicks in Embodiment 1 of the present invention includes a soft wick 5. The soft wick 5 includes a PCB board 51 made of PET transparent film material. The PCB board 51 is provided with a number of LED chip wafers 52. The PCB board 51 and the LED chip wafers 52 are sealed with milky white soft silicone 53 on their outer sides.

[0021] Among them, the soft LED chip 5 is set as a single piece, and the MCU wafer 7 on the PCB board 51 is electrically connected to the positive and negative pins 2 through the corresponding positive and negative pin pads 8. The MCU wafer 7 is a 2200K-6500K LED chip wafer or an RGB LED chip wafer.

[0022] At this time, the LED chip 52 is electrically connected to the positive and negative pins 2 through the MCU chip 7. The wick pin colloid 3 is fixed on the positive and negative pins 2. The wick pin colloid 3 passes through the soft plug 4 and is fixed on the soft plug 4. After the soft wick 5 extends into the bulb 6, the soft plug 4 is tightly attached to the inner wall of the bulb 6. The sealing ring 41 on the soft plug 4 is stuck to the bottom of the bulb 6. The soft plug 4 is fixed inside the lamp holder 1. The lamp holder 1 is screwed to the outside of the bulb 6. The positive and negative pins 2 are respectively connected to the positive and negative terminals of the lamp holder 1.

[0023] The lamp holder 1 is connected to the wire 10 through the lamp holder mechanism. One end of the wire 10 is connected to the plug 9, and the other end is connected to the tail end interface 11 that is plugged into another set of plugs 9.

[0024] Optionally, the lamp holder mechanism includes lamp holders without suspension wires and lamp holders with suspension wires.

[0025] Specifically, the non-suspended lamp holder includes several connectors 14 evenly spaced on the wire 10, and a lamp holder 12 is provided inside the connector 14. Positive and negative electrode springs 13 are installed in the corresponding slots at the bottom of the lamp holder 12. The wire 10 is placed in the wire groove 17 of the lamp holder 12. The sharp ends of the positive and negative electrode springs 13 are exposed in the corresponding wire grooves 17. When the bottom cover 18 of the lamp holder is pressed tightly by the machine, the wire 10 is pierced by the positive and negative electrode springs 13 under pressure, and contacts the wire core inside the wire 10 to achieve conductivity.

[0026] At this time, the positive and negative electrode springs 13 are installed in the corresponding slots at the bottom of the lamp holder 12. The sharp ends of the positive and negative electrode springs 13 are exposed in the corresponding wire grooves 17. When the wire 10 is placed in the wire groove 17 and the lamp holder bottom cover 18 is pressed by the machine, the wire 10 is pierced by the positive and negative electrode springs 13 under pressure and comes into contact with the wire core to achieve conductivity.

[0027] Specifically, the pendant lamp holder includes several T-shaped brackets 16 connected at equal intervals to the wire 10 and a pendant wire 15 connected to the T-shaped brackets 16. The T-shaped bracket 16 includes a front T-shaped frame 161 and a rear T-shaped frame 162 that are clamped on the front and rear sides of the wire 10. The front T-shaped frame 161 and the rear T-shaped frame 162 are connected and fixed by copper nails 163. The pendant wire 15 passes through the connector 14 and is fixed with positive and negative electrode springs 13 by press riveting. The positive and negative electrode springs 13 are installed in the corresponding slots of the lamp holder 12. The lamp holder 12 is set in the connector 14. The T-shaped bracket 16 has a groove for installing the wire 10 and the pendant wire 15. The copper nails 163 pierce the intersection points of the corresponding positions of the wire 10 and the pendant wire 15 to achieve conductivity.

[0028] At this time, the positive and negative electrode springs 13 are fixed to the suspension wire 15 by press riveting, and then installed into the corresponding slot of the lamp holder 12. The wire 10 and the suspension wire 15 are installed into the corresponding wire groove in the T-shaped seat 16, and the copper nail 163 is used to pierce the corresponding intersection point to achieve conductivity.

[0029] In practical applications, after plugging the plug 9 into the power supply, the wire 10 is energized. The wire 10 energizes the lamp holder 1 through the positive and negative spring contacts 13, and finally supplies power to the lamp chip wafer 52 through the positive and negative pins 2.

[0030] A PCB board 51 is formed using a PET transparent flexible board as a substrate. R, G, B, C (cool white), and W (warm white) LED bead wafers and a DC carrier decoding MCU wafer are simultaneously packaged on the transparent flexible board. The surface is covered with milky white soft silicone 53 to achieve RGB, RGBW, RGBCW, CW and other light-emitting effects of the light strip.

[0031] It should be noted that the carrier decoding MCU works as follows: the controller module transmits the voltage pulse signal carrying information data to the MCU wafer 7 through two wires with positive and negative terminals. After the MCU wafer 7 parses the information data contained in the voltage pulse signal, it controls the switching of each IO port and adjusts the output power according to the information data, thereby controlling the on / off state of the corresponding LED wafer 52 of each IO port, realizing the color switching of the soft LED chip 5 and various dynamic color effects.

[0032] Example 2 like Figures 8 to 14 As shown, the difference between this embodiment 2 and embodiment 1 is that the flexible wick 5 is provided with two roots.

[0033] Example 3 The difference between this embodiment 3 and embodiment 1 is that the flexible wick 5 has three wicks.

[0034] This invention provides a highly efficient, stable bulb with a variable number of wicks. The bulb uses a soft rubber plug to secure the soft wick, which is tightly fitted to the inner wall of the bulb shell. A sealing ring on the soft rubber plug engages with the bottom of the bulb shell, creating a double seal and positioning that ensures a secure and stable installation with high sealing reliability. Furthermore, the soft wick is made using a PCB board constructed from PET and PC transparent film materials, sealed with milky white soft silicone, reducing material costs. The bulb can be configured with single, double, or triple wicks, allowing for flexible selection of the required number. Simultaneously, the bulb holder is connected to the wire via a lamp base mechanism. For lamp bases without a suspension wire, a machine presses the base cover, causing the positive and negative electrode springs to pierce the wire insulation and contact the wire core for conductivity, eliminating the need for wire stripping and making it suitable for automated production. For lamp bases with a suspension wire, copper nails pierce the intersection of the wire and suspension wire to achieve conductivity. The copper nails simultaneously provide both fixation and conductivity, simplifying the production process, improving efficiency, and increasing the first-pass yield.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
