[0029] In a further embodiment, the filament frame 20 further includes a positioning hole 24, which is disposed in the second frame 212.

[0030] Please see the appendix Figure 3 ,for Figure 1 The diagram shows the structure of a filament circuit board 30. The filament circuit board 30 includes a board body 31 and circuit units 32. The board body 31 can be a ceramic substrate, and the circuit units 32 are stacked on the board body 31.

The pad array 321 includes multiple pads 3211 arranged in a row along the length of the board body 31, and each pad array 321 has a first end 321a and a second end 321b. The conductive interface 322 is electrically connected to each conductive lead 22 in a one-to-one correspondence, and includes a first conductive interface 3221 and a second conductive interface 3222. The first conductive interface 3221 is located adjacent to the first end 321a, and the second conductive interface 3222 is arranged in a row along the width of the board body 31, adjacent to the first conductive interface 3221.
