PROBLEM TO BE SOLVED: To provide a pilot lamp with high visibility and low cost by using a light emitting diode as a light source. SOLUTION: A light emitting diode 14 is lit, light from each light emitting diode 14 is reflected by the outer circumferential surface of a reflector 15 having a conical trapezoid shape and hollow structure, and passes through the inner circumferential surface of a case main body 11 in which a concave lens part 11c is formed. Thereby, in spite of using the light emitting diode 14 with high directivity arranged so as to face the front surface of the case main body 11, the brightness on the outer circumferential surface of the case main body 11 is increased. Even in the case that a pilot lamp 10 is fixed to a high portion, high visibility is obtained. Light of the light emitting diode 14 is reflected by a reflector 15 and passes through not only the inner circumferential surface but also a protruded stripe lens part 11e on the inside of the front surface through a small diameter opening 15d. Light shines not only on the outer circumferential surface but also on the front surface, and visibility is enhanced. |
