Description

Technical Field

[0001] This utility model relates to the field of LED filament core technology, specifically to an LED filament core that can be quickly manufactured and assembled. Background Technology

[0002] LED filaments, also known as LED light columns, previously required the addition of optical devices such as lenses to achieve a certain illuminance and illumination area, which affected the lighting effect and reduced the energy-saving efficiency of LEDs. LED filaments can achieve 360° omnidirectional light emission, large-angle light emission without the need for lenses, realize three-dimensional light source, and bring an unprecedented lighting experience.

[0003] Application number CN202322534297.7 discloses an LED filament lamp core column for adjustable color temperature, belonging to the field of LED filament lamp technology. It addresses the problem that in existing LED filament lamp core columns, the filament is only connected magnetically. During the connection and processing of the LED filament lamp core column with the glass shell, vibration or shaking can easily cause poor contact of the filament, affecting the later performance. The invention includes a lamp holder, with a lamp core body at the top. A first diode is fixedly installed at the top of the lamp core body, and a connecting ring is fixedly installed at the top of the first diode. Several mounting grooves are provided on the sides of both the connecting ring and the lamp core body. A second diode is installed on the side of the first diode. This invention, through the design of a rotating ring, annular groove, spring, arc block, locking groove, cavity, recess, and connecting rod, facilitates the installation and removal of the second diode, improves installation and removal efficiency, enhances the placement stability of the second diode, and increases practicality.

[0004] This structure is designed to install and fix the main body of the lamp wick. However, when dealing with flexible lamp wicks and other structures, the two ends of the easily deformable flexible strip are fixed by the connecting ring and locking groove, leaving the core of the lamp wick without support. This reduces the fixing effect of the structure on such lamp wick columns. Utility Model Content

[0005] The purpose of this invention is to provide an LED filament core column that can be quickly manufactured and assembled, solving the problem of fixing soft LED filaments.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an LED filament core that can be quickly manufactured and assembled, comprising a housing and an mounting structure. The mounting structure is installed on the inner wall of the housing. The housing includes a sleeve, and the inner wall of the sleeve has a sloping groove. A conical block is inserted into the inner wall of the sloping groove, and a filament is fixedly connected to the inner wall of the conical block. A bead is sleeved on the outer wall of the top of the filament, and a leather sleeve is sleeved on the outer wall of the top of the bead. The purpose of this setup is that, during the use of the LED filament, the filament is first inserted into the conical block. The sleeve perfectly fits the conical block through the inclined groove. The conical block is then slid upwards onto the inclined groove of the sleeve. A bead is used to fix the top edge of the filament around its perimeter. The arc groove at the top of the sleeve fixes the bottom edge of the bead around its perimeter. A sealing ring fills the gap between the bottom of the bead and the arc groove of the sleeve, ensuring a tight fit. This allows the filament to be vertically fixed inside the sleeve. The sleeve provides external safety protection for the filament. A threaded ring secures the sleeve to the outer cover. In this way, the conical block and the bottom of the filament are both fixed inside the sleeve. Flanges one and two seal the top and bottom ends of the sleeve respectively. A retaining block at the top of the sleeve secures the triangular part of flange one, fixing flange one to the top of the sleeve. The top of the bead is fixed by a sleeve, and a screw is installed in the internal thread of the holes around flange one. Flange two is fitted onto the bottom of the sleeve, and the outer cover limits the movement of the bottom of flange two. Flange two is rotated upward to align with the bottom end of the screw, and the two are rotated and tightened to fix the bottom end of the screw in flange two. Thus, the screw fixes the upward movement of flange one. When the filament needs to be removed, the outer cover and flange two are rotated to remove them. Then, the conical block and bead are removed from the sleeve in sequence. Finally, the conical block and bead are removed from the outside of the filament. This structure can vertically fix the filament in the sleeve for safety protection. The sleeve, conical block and bead are glass products with light transmission, and the filament can emit light outward through the three. This structure can be adapted to fix easily deformable filaments and is easy to install and remove, enhancing the practicality of filaments with different hardness.

[0008] Furthermore, a sealing ring is installed on the inner top wall of the sleeve, which fits snugly against the top gap of the sleeve. The sealing ring is located on the outer perimeter of the bottom of the bead. The purpose of this arrangement is that, during the use of the LED filament, the arc-shaped groove at the top of the sleeve fixes the bottom perimeter of the bead, and the sealing ring fills the gap between the bottom of the bead and the arc-shaped groove of the sleeve to ensure a snug fit.

[0009] Furthermore, a flange is fixedly connected to the outer wall of the sleeve, and a second flange is provided directly below the first flange. The top protrusion of the bead extends upward into the interior of the sleeve, and the flange is fitted onto the top outer wall of the sleeve. The purpose of this arrangement is that, during the use of the LED filament, the flange is fixed, and the sleeve connected to it limits and fixes the top of the bead.

[0010] Furthermore, a set of positioning grooves is provided on the inner wall around the bottom of the flange one, and a set of locking blocks is provided on the outer wall around the top of the sleeve, with the locking blocks embedded in the positioning grooves. The purpose of this arrangement is that, during the use of the LED filament, the locking blocks at the top of the sleeve are used to fix the triangular part of the sleeve, so that the flange one is fixed to the top of the sleeve, and the top of the bead is limited and fixed by the sleeve.

[0011] Furthermore, a threaded ring is provided on the outer wall of the bottom end of the sleeve, and an outer cover is fitted onto the bottom of the sleeve. The outer cover is threadedly connected to the outer wall of the sleeve via the threaded ring. The purpose of this arrangement is to install and fix the sleeve and the outer cover together with the threaded ring during the use of the LED filament, so that the conical block and the bottom of the filament are fixed together inside the sleeve.

[0012] Furthermore, the second flange is fitted onto the bottom outer wall of the sleeve, and the second flange is located between the sleeve and the outer cover. Screws are inserted into the inner walls of both the second and first flanges. The purpose of this arrangement is that, during the use of the LED filament, the outer cover limits the bottom movement path of the second flange. By rotating the second flange upwards to align it with the bottom end of the screw, and then tightening them together, the second flange fixes the bottom end of the screw, thereby fixing the upward movement path of the first flange.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a bead and a conical block to slide the conical block from bottom to top into the inclined groove of the sleeve. The bead fixes the top of the filament around the perimeter, and the arc groove at the top of the sleeve fixes the bottom of the bead around the perimeter. The sealing ring fills the gap between the bottom of the bead and the arc groove of the sleeve to make them fit together, so that the filament is vertically fixed inside the sleeve. The sleeve provides safety protection for the outside of the filament.

[0015] (2) By setting up the screw, the locking block and the positioning groove, the locking block at the top of the sleeve fixes the triangular part of the flange one, so that the flange one is fixed at the top of the sleeve. The bottom end of the screw is fixed by the flange two, so that the screw fixes the upward movement path of the flange one, and the ball is fixed inside the sleeve.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A conical block 202 is inserted into the inner wall of the inclined groove 102. A filament 201 is fixedly connected to the inner wall of the conical block 202. A bead 203 is sleeved on the outer wall of the top of the filament 201. A leather sleeve 109 is sleeved on the outer wall of the top of the bead 203. The purpose of this setup is that, during the use of the LED filament, the filament 201 is first inserted into the conical block 202, and the sleeve 101 perfectly embeds the conical block 202 through the inclined groove 102. The conical block 202 is then slidably inserted from bottom to top onto the inclined groove 102 of the sleeve 101. The top edge of the filament 201 is fixed around the perimeter by the bead 203, and the top arc groove of the sleeve 101 fixes the bottom edge of the bead 203 around the perimeter. The sealing ring 105 fills the gap between the bottom of the bead 203 and the arc groove of the sleeve 101 to ensure proper adhesion. The sleeve 101 is vertically fixed inside the sleeve 101, providing external safety protection for the filament 201. The sleeve 101 is then installed and fixed to the outer cover 104 via the threaded ring 103. This secures the tapered block 202 and the bottom of the filament 201 together within the sleeve 101. Flanges 106 and 110 seal the upper and lower ends of the sleeve 101 respectively. A retaining block 108 at the top of the sleeve 101 secures the triangular portion of flange 106, thus fixing flange 106 to the sleeve 101. At the top, the top of the ball 203 is limited and fixed by the sleeve 109. The screw 100 is installed in the internal thread of the holes around the flange 106. The flange 2 110 is fitted onto the bottom of the sleeve 101, and the outer cover 104 limits the bottom movement path of the flange 2 110. The flange 2 110 is rotated upward to align with the bottom end of the screw 100. The two are rotated and tightened to fix the bottom end of the screw 100 with the flange 2 110. Thus, the screw 100 fixes the upward movement path of the flange 106. When it is necessary to remove the filament 201, the outer cover is rotated. Remove 104 and flange 210, then take out the conical block 202 and the bead 203 from the sleeve 101 in sequence, and finally remove the conical block 202 and the bead 203 from the outside of the filament 201. This structure can vertically fix the filament 201 inside the sleeve 101 for safety protection. The sleeve 101, conical block 202 and bead 203 are glass products with light transmission. The filament 201 can emit light outward through the three. This structure can be adapted to fix the easily deformable filament 201 and is easy to install and remove, which enhances the practicality of filaments 201 with different hardness.

The top protrusion of the bead 203 extends upward into the interior of the sleeve 109. Flange 106 is fitted onto the top outer wall of the sleeve 101. The purpose of this arrangement is that, during the use of the LED filament, it is fixed by flange 106, so that the sleeve 109 connected to it limits and fixes the top of the bead 203.

[0028] A set of positioning grooves 107 are provided on the inner wall around the bottom of flange 106, and a set of locking blocks 108 are provided on the outer wall around the top of sleeve 101. The locking blocks 108 are embedded in the positioning grooves 107.
