Document Type and Number:
Japanese Patent JP2017228515
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a zoom lamp.SOLUTION: A zoom lamp includes: a lamp body with which a storage groove 31 is formed; a light-emitting component 42 which is stored in the storage groove; a movable ring 50 including multiple guiding posts 51 that are protrusively provided on an outer wall, and resilient members 52 attached to the guide columns; a lens 60 which is fixed to the movable ring; and a rotation ring 70. An annular coupling groove 32 and multiple sliding grooves 33 are formed on an inner wall of the lamp body, and the resilient members provide resistance in a direction that is opposite to a sliding direction of the guiding posts. A hook 71 that is slid along the annular coupling groove is protrusively provided on an outer wall of the rotation ring, and inclined grooves 72 that are abutted to the guiding posts in a slidable manner are formed in the rotation ring. When rotating the rotation ring, the rotation ring is rotated in a circumferential direction oppositely to the lamp body and along the storage groove, and the lens that is fixed within the movable ring is moved in an axial direction by an interaction among the gradient grooves, the guiding posts, and the resilient members, such that a light-emitting angle is controlled.SELECTED DRAWING: Figure 3
