Patent attributes
A zoom LED lamp comprises a chip receiving cylinder, a chip fixing column, a lens receiving cylinder, and a fixing cylinder. The chip receiving cylinder comprises a radial positioning ring, a receiving groove, and an elastic sealing ring. The chip fixing column comprises a column body and at least two ears. The two ears are fixed in the chip receiving cylinder. The lens receiving cylinder comprises a lens cylinder and two openings respectively inserted into the two ears. The zoom LED lamp not only fixes the position of the lens cylinder in the radial direction, but also allows the elastic sealing ring to fix the position of the lens cylinder in the axial direction of the chip receiving cylinder when no external force is applied. In addition, the sliding path of the lens cylinder in the axial direction of the chip receiving cylinder can also be limited, so that the irradiation range of the zoom LED lamp can be regulated.
