Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0040] refer to Figure 1-6 As shown, an LED lamp with an adjustable light output angle includes a glass plate 1, an LED light source 2, a lamp tube 3, a light-shielding layer assembly, and an external control circuit; the divergent LED light source 2 is fixed in the middle of the lamp tube 3 , the size of the LED light source 2 is correspondingly matched with the elastic shading layer assembly, and the shading layer assembly is composed of a plurality of shading blocks 5 and a spring frame 4. The lamp tube 3 is composed of two parts, the tube wall and the tube bottom. The tube wall and the tube bottom are respectively placed with a horizontal direction energized coil 7 and a vertical energized coil 8, which can respectively generate magnetic fields in two directions perpendicular to each other. When the energized coils in two directions When the magnitude and direc...
