[0002] In the prior art, the application of linear light sources, especially flexible LED filaments, is becoming increasingly widespread. Their design flexibility and high efficiency are favored by the market. To further improve the installation convenience and aesthetics, many designs adopt a magnetic connection method, that is, the end of the flexible LED filament is magnetically connected to the magnetic component on the light-transmitting carrier through a connecting magnetic component. However, this design still has some deficiencies in practical applications, and the specific analysis is as follows: The existing magnetic connection method mainly focuses on installation convenience. Since the magnetic component in the disclosed technology is a non-light-transmitting structure, when the flexible LED filaments are combined, the magnetic connection section often does not emit light, and it is impossible to form diverse lighting effects, lacking a sense of hierarchy and variation; the structure of the magnetic component is single and lacks ornamental value. Summary of the Utility Model

[0011] Further, the first LED chip or the second LED chip is any one of a blue light chip, a green light chip or a red light chip.

[0016] Compared with the prior art, in the present utility model, by introducing the light-transmitting beads as pendants and placing them in the light-transmitting carrier, and specially arranging a light source segment at the end of the filament, it is different from the light-emitting light source of the rest of the filament.

[0034] Please refer to Figure 1 and Figure 2 As shown, the lamp with a linear light source inside the present utility model includes a lamp with a linear light source inside, which includes a light-transmitting carrier 1 and at least one LED filament 2.

The first LED chip 211 or the second LED chip 221 is any one of a blue light chip, a green light chip or a red light chip. At the end of the LED filament, light-transmitting beads are respectively sleeved outside each second light source section. These light-transmitting beads not only increase the aesthetics of the product, but also play a role in protecting the LED chips and enhancing the light-transmitting effect. The material of the light-transmitting beads is crystal, plastic or glass, and the plastic light-transmitting beads can also be mixed with fluorescent powder to achieve a special lighting effect. The design of the light-transmitting beads is introduced, and a variety of material options are provided, which increases the aesthetics of the product, meets the user's needs for personalization and decoration, and solves the problem of the single appearance design of the existing linear light source lamp.
[0036] A first light-transmitting glue layer 212 is coated on the front and back of the substrate, and the first light-transmitting glue layer 212 covers the first light source section 21; if necessary, the LED filament 2 can be sleeved with a heat-shrinkable tube along the length direction, and after being heated, the heat-shrinkable tube covers the LED filament 2 to protect the LED filament 2 and increase the tensile strength of the whole filament.
[0037] The second light source section 22 can be passed through the light-transmitting bead 4 by a bracket, so that the light is directly transmitted through the light-transmitting bead 4, and a fluorescent glue is filled between the installation hole 41 in the light-transmitting bead 4 and the end of the filament, so that the light emitted by the second light source section 22 at the end is excited by the fluorescent glue to form light of the required color and color temperature; or the light-transmitting bead 4 is mixed with fluorescent powder, and the light emitted by the second light source section 22 is directly excited by the light-transmitting bead to emit light of the required color and color temperature.
[0038] Or, a second light-transmitting glue layer 222 is coated on the front and back of the substrate 20, and the second light-transmitting glue layer 222 covers the second light source section 22, then the second light source section 22 is bonded to the installation hole 41 in the light-transmitting bead 4 by applying glue through the second light-transmitting glue layer 222.
[0039] The light-transmitting bead 4 is a crystal bead, a plastic light-transmitting bead or a glass bead, and the plastic light-transmitting bead includes a plastic fluorescent bead mixed with fluorescent powder.
[0040] The light-transmitting carrier 1 is a bulb 11 or a light-transmitting cover 12. A lamp holder 5 or a lamp socket 6 is provided outside one end of the bulb 11 or the light-transmitting cover 12. The driving power supply 3 is arranged inside the lamp holder 5 or the lamp socket 6. A first magnetic attracting member 7 is arranged on the inner wall or the outer wall of the bulb 11 or the light-transmitting cover 12 away from the lamp holder 5 or the lamp socket 6. A second magnetic attracting member 8 is embedded in the light-transmitting bead 4 at the outermost end of the LED filament 2. The end of the LED filament 2 is magnetically connected to the first magnetic attracting member 7 through the second magnetic attracting member 8. The LED filament is the core component of this product, and it includes a substrate and a first LED chip and a second LED chip arranged on the substrate. These chips are connected in series, in parallel or in a hybrid manner to form a first light source section and a second light source section. The head end of the LED filament is electrically connected to the driving power supply, and its end extends into the light-transmitting carrier.
[0041] For the convenience of assembly, a first magnetic attracting member is arranged on the inner wall or the outer wall of the light-transmitting carrier of this product, and a second magnetic attracting member is embedded in the light-transmitting bead at the outermost end of the LED filament. Through magnetic connection, users can easily fix the LED filament on the light-transmitting carrier. It realizes convenient assembly and solves the problem of the cumbersome assembly process of traditional linear light source lamps. The bulb 11 is a glass bulb or a light-transmitting plastic bulb.

An installation hole 41 and a magnetic attracting member embedding hole 42 are arranged on the light-transmitting bead 4. The second magnetic attracting member 8 is embedded and connected in the magnetic attracting member embedding hole 42. Further, after the second magnetic attracting member 8 is placed in the magnetic attracting member embedding hole 42, filling glue is injected into the magnetic attracting member embedding hole 42 and a plug 420 is sealed outside the embedding hole, so that the overall shape of the light-transmitting bead is not affected by the embedding hole and the aesthetic feeling is not affected, and the second magnetic attracting member 8 is installed in a hidden manner. The first magnetic attracting member 7 and the second magnetic attracting member 8 can be selected from any combination of permanent magnets, magnetic steels or magnets and magnetizable metals, thus ensuring a firm connection between the LED filament 2 and the light-transmitting carrier 1, and also providing a variety of magnetic attraction options to adapt to different application scenarios and user requirements.
[0042] In the implementation process, the light-transmitting bead 4 not only serves as an element for aesthetics and protecting the LED chip, but also undertakes the task of realizing special lighting effects. When the light emitted by the second light source section 22 passes through the light-transmitting bead 4, if the light-transmitting bead is filled with fluorescent glue or mixed with fluorescent powder, the light will be excited to form the required color and color temperature. Users can select suitable light-transmitting bead materials and fluorescent effects according to different scenarios and requirements, so as to create a more diverse and personalized lighting experience. This design enables users to select suitable light-transmitting bead materials and fluorescent effects according to different scenarios and requirements, so as to create a more diverse and personalized lighting experience.
[0043] The magnetic connection demonstrates its unique advantages in specific implementations. The magnetic attraction force between the first magnetic member 7 and the second magnetic member 8 is carefully designed to not only ensure that the LED filament 2 can be firmly fixed on the light-transmitting carrier 1, but also facilitate the user to separate the filament and magnetically straighten it when needed.
[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
