Embodiment Construction
[0027] The LED filament light emitting strip of the present invention is such as image 3 As shown, two rows of LED chips are included, and the lower row of LED chips is arranged on the upper row of LED chips. The LED chips 1 in the lower row are arranged at intervals, and the LED chips in the upper row are respectively overlapped between two adjacent LED chips 1 in the lower row. The LED chips in the lower row are opposite to the light emitting surface of the LED chips in the upper row. The positive electrode and the negative electrode of the LED chip in the upper row are respectively welded to the negative electrode and the positive electrode of the two adjacent LED chips 1 in the lower row to form a chip bar, and the fluorescent glue 5 is coated on the chip bar.
[0028] The preparation steps of the above LED filament light-emitting strip are as follows:
[0029] (1) Such as figure 1 As shown, the lower row of LED chips are arranged, and the LED chips in the lower row are arran...
