摘要： A novel Christmas light comprises a head and a shade. A lighting device is mounted inside the shade. The lighting device comprises an LED light, a printed circuit board and a power supply module. The LED light is a patch type LED light. The printed circuit board comprises a first printed circuit board and a second printed circuit board. The first printed circuit board is positioned upright. The second printed circuit board is placed flat below the first printed circuit board. The first printed circuit board and the second printed circuit board are perpendicular to each other and fixedly connected with each other. The patch type LED light is welded to a lower bottom surface of the second printed circuit board. The power supply module is mounted on the first printed circuit board. The first printed circuit board and the head are fixedly connected with each other.
