Example Embodiment
[0020] Example: an LED lamp, such as figure 1 As shown, it includes a lamp cap 7, a bulb 8, and an LED light-emitting module 9 is arranged in the bulb 8, such as figure 2 , image 3 As shown, the LED light-emitting module 9 includes a glass stem 1 and two circuit boards 2. Among the two circuit boards, one of the circuit boards is provided with a longitudinal gap 3 in the center of the half, and the other A longitudinally arranged notch 3 is provided in the center of the lower half of a circuit board. The two circuit boards 2 are plugged together in a cross shape through the corresponding notch 3 and fixed by welding; lead 4 and 4 in the glass core column 1 It is welded and fixed to the lower end of one of the circuit boards 2. A cross-shaped circuit board 5 is fixed on the top of the two circuit boards 2. The planes of the two circuit boards 2 are perpendicular to the plane of the cross-shaped circuit board 5. A plurality of LED chips 6 are soldered on the two cross-shaped ci...
