Title:
FIXING STRUCTURE OF CIRCUIT BASE BOARD AND LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2023152710
Kind Code:
A
Abstract:
To provide: a fixing structure of a circuit base board reducing contact between a fixing structure and an effective region where electric elements on the circuit base board are placed, having a simple configuration, and easily mounted; and a lighting device.SOLUTION: A fixing structure of a circuit base board and a lighting device relate to a lighting technology field. The fixing structure of a circuit base board includes: a storage container; a first position restriction unit provided on an annular base surface of the storage container and abutting against a first surface of the circuit base board; and a second position restriction unit attachable to or detachable from the storage container and abutting against a second surface of the circuit base board. An opening diameter at a position where the circuit base board of the storage container is mounted is larger than the outer diameter of the circuit base board or is equal to the outer diameter. The fixing structure of the circuit base board effectively eliminates stress received when the circuit base board is fixedly mounted, reduces contact between the fixing structure and an effective region where electric elements on the circuit base board are provided, is simple in a configuration, and can be easily mounted.SELECTED DRAWING: Figure 3
