A focusing structure for an LED lamp. LED chips (2) are provided in a main body (1) of the LED lamp, and the front end of the main body is also provided with a lens assembly (3);at least one of the LED chips is not located on the axis of the LED lamp, and at least two groups of lenses (31) with different degrees are provided on the lens assembly, the location of each group of lenses corresponding to the location of a corresponding LED chip on the same circumference;and the lens assembly is connected to the main body with structures capable of relatively rotating and snap-fitting.The LED lamp can achieve the focusing function by rotating the lens assembly to make the lenses with different degrees correspond to the LED chips.Compared with the focusing mode of changing the distance between chips and lenses, this structure has no light loss, and can achieve the focusing function of various focal distances. |
