Document Type and Number:
Japanese Patent JP2021030342
Kind Code:
A
Abstract:
To achieve a lighting device for hand-held type equipment which does not cause both a deviation of an optical axis of a lighting device and the deviation of the optical axis between the lighting device and a housing of an equipment side where the lighting device is attached and allows replacement of parts.SOLUTION: A lighting device 1 is attached to a housing of hand-held type equipment. The lighting device 1 includes an LED substrate 2 where an LED 3 is loaded and a substrate attachment tool 10 where the LED substrate 2 is mounted for attaching the LED substrate 2 to the housing. On the substrate attachment tool 10, an engagement retaining part 11 which engages the LED substrate 2 for detachably retaining and a lens part 12 are integrally provided. The engagement retaining part 11 has a nail part 13 and retains the LED substrate 2 by engaging the LED substrate 2 while an optical axis of the LED 3 is aligned with an optical axis of the lens part 12. The lens part 12 fits to an illumination opening part formed on the housing with a protrusion and a recess and has a positioning function relative to the housing.SELECTED DRAWING: Figure 1
