DETAILED DESCRIPTION

[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] This embodiment provides a filament with a suspended light-emitting segment and a lamp using the filament, which mainly meet market demand, make the light-emitting structure present non-integrated light emission, and make the light-emitting part present a suspended effect.

[0038] Example 1:

[0039] like Figure 1 As shown, a filament with a suspended light-emitting segment includes a first transparent segment 1 and a light-emitting segment 2, wherein the first transparent segment 1 and the light-emitting segment 2 are connected in series to form a linear filament structure; the filament of the light-emitting segment further includes a positive pin 4 and a negative pin 5, wherein the positive pin 4 and the negative pin 5 are arranged at the front end of the first transparent segment 1;

[0040] like Figure 3 and Figure 9 As shown, the first transparent segment 1 is provided with a positive printed circuit layer 11 and a negative printed circuit layer 12 along the length direction, the positive pin 4 is electrically connected to the positive printed circuit layer, and the negative pin 5 is electrically connected to the negative printed circuit layer 12; specifically, the positive printed circuit layer 11 and the negative printed circuit layer 12 are electrically connected to the upper end of the light-emitting segment 2.

[0041] It is worth noting here that the light-emitting position of the filament is at the position of the light-emitting segment 2, and it is not an integral light-emitting type. A first transparent segment 1 is provided above the light-emitting segment 2. The positive pin 4 and the negative pin 5 on the first transparent segment 1 are connected to the power supply, so that the light-emitting part of the light-emitting segment 2 can appear to be suspended.

[0042] This setting can enhance the beauty of the filament, create a unique lighting effect, and improve the user experience. It is worth noting that users can adjust the length and position of the light-emitting part according to actual needs to meet the needs of different application scenarios.

[0043] In this embodiment, if Figure 5 As shown, the light-emitting segment 2 includes a transparent flexible substrate 20 and a plurality of light-emitting chips 21 arranged on the front surface of the transparent flexible substrate 20. The plurality of light-emitting chips 21 can be connected in series, in parallel, or in series and parallel to form a light-emitting module. The two ends of the light-emitting module are electrically connected to the lower ends of the positive printed circuit layer 11 and the negative printed circuit layer 12, respectively.

[0044] The light emitting module is powered via the positive pin 4 and the negative pin 5 , so that the light emitting chip 21 can emit light.

[0045] like Figure 5 As shown, the front and back surfaces of the transparent flexible substrate 20 are coated and cured with a light-transmitting adhesive 22 , and the light-emitting chip 21 is wrapped with the light-transmitting adhesive 22 to fix the light-emitting module.

[0046] It is worth noting that the transparent flexible substrate 20 can be made of a polyimide film or a polyester film, such as Figure 3 As shown, the front and back surfaces of the extended portions of the transparent flexible substrate 20 on the first transparent segment 1 and the second transparent segment 3 are coated with a cured transparent adhesive 14. At this time, the positive electrode printed circuit layer 11 and the negative electrode printed circuit layer 12 located inside the first transparent segment 1 can be protected by the cured transparent adhesive 14, reducing the risk of damage to the positive electrode printed circuit layer 11 and the negative electrode printed circuit layer 12.
