PURPOSE:To improve the visibility and the guidance effect by reflecting the light of a lamp to the taxiway direction. CONSTITUTION:A reflecting surface 21 reflects the light of a lamp 30 to the direction (a) oblique against the optical axis O-O, and the light is reflected forward obliquely through an opening part of a casing 10. A reflecting surface 22 reflects the light to the direction in parallel with the optical axis O-O, and the light is reflected forward straight through the opening part of the casing 10. A light diffusing layer 13 diffuses the transmitted light, but since the quantity of the transmitted light in the oblique direction is larger than that of the transmitted light directed to other directions, quantity of the light in the oblique direction can be increased. Consequently, in the case where a taxiing guidance lamp device is seen from the front side obliquely, the luminance is improved to facilitate the visual recognition of the taxiing guidance lamp device and improve the guiding function. A part of the light of the lamp 30 is reflected to the forward direction (b) straight, seen from the front surface is maintained high to improve the visibility. Guidance effect can be thereby showed effectively. |
