Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] A kind of flexible LED filament strip that the present invention proposes, such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, it includes a strip-shaped flexible metal circuit board 1, two metal electrodes 2 and a plurality of LED chips 3. The strip-shaped flexible metal circuit board 1 is composed of a strip-shaped flexible metal substrate 11 and a The printed circuit layer 12 on the front is composed of two metal electrodes 2 that are installed on the two ends of the strip-shaped flexible metal substrate 11 one by one. The two metal electrodes 2 are electrically connected to the printed circuit layer 12 respectively. The strip-shaped flexible metal substrate 11 A plurality of chip mounting areas 13 are reserved on the front side of the front surface, and each chip mounting area 13 is bonded with two formal...
