| 摘要 | PURPOSE: To illuminate an operating knob easily without modifying he outer dimensions of a cigar lighter by providing the actuating button of a firing plug made of a light transmitting material with a conical recess for introducing light rays not only to a luminous ring but also an actuating button while forming a second reflection surface extending around the central axis at an inclination angle α. CONSTITUTION: Light passage openings 14 are made in the walls 12, 13 of a lighter socket 4 and a firing plug 3. First light rays incident to a first reflection surface 15 passes through the openings 14 and reflects radially into an illumination sleeve 2. Light rays reflected radially into an actuating button 7 proved slidingly in a knob 8 in the direction of a normal S to the central axis ZA is reflected outward on a second reflection surface 16 in parallel with the central axis to a range 23 in front of the button 7. A conical recess 17 is made in the lower surface of the button 7 to form second reflection surface 16 extending circumferentially around the central axis ZA in parallel with a first reflection surface 15 at an inclination angle α=45°.
