PURPOSE:To enable the radiation of a light reflected on a reflecting surface to an illumination target by refracting a light emitted from a luminescent bulb side part by the circumferential side lens part of the lens body of a lamp device and radiating said light on the reflecting surface as a parallel light. CONSTITUTION:An outer housing 29 having a lamp device 20 mounted to its inside is provided along the outer shape of an inner housing 30, and an outer lens 31 is connected to the opening part in the front thereof. Each Aiming bolt 32 is longitudinally passed through and screwed into the upper part and side part of the housing 29. The tongue piece on the rear surface side of the housing 30 is connected to the top end side of the bolt 32 so that the illuminating direction can be adjusted by the rotation of the aiming bolt 32. A lens body 25 is installed to the luminescent part of a luminescent bulb 33 in such a manner as to enclose the bulb 33, and the base end part of the circumferential side lens part 27 of the lens body 25 is bonded to the front surface of the housing 30, whereby the light from the circumferential side of the bulb 33 is refracted by the lens body 25 and radiated frontward. |
