<P>PROBLEM TO BE SOLVED: To provide an embedded marker lamp 11 in which a projected height of a lamp body 14 from a road surface is not increased and a light distribution of a low angle against the road surface can be obtained. <P>SOLUTION: The lamp body 14 includes two light emitting windows 31 arranged mutually in opposite directions, each of which can emit light laterally; and a light emitting groove 32 from each of the light emitting windows 31 toward an outer circumferential portion of the lamp body 25. Two light emitting windows 31 are arranged symmetrically about the central position 25a of the lamp body 25, and at least one portion of each the light emitting windows 31 is arranged on an opposite side to a light emitting direction a from the central position 25a of the lamp body 25. A distance between the light emitting window 31 in a light emitting direction a and the outer circumferential portion of the lamp body 25 is prolonged to emit light of a low angle against the road surface. <P>COPYRIGHT: (C)2009,JPO&INPIT |
