PROBLEM TO BE SOLVED: To provide an aviation marker lamp which can improve a long service life and a luminous efficiency of a light source, and control an optimum luminous control with a low cost by constructing it by the use of a LED(light emission diode). SOLUTION: This marker lamp 1 is constructed such that a colored fun- shaped reflection board 3c which is provided with an aperture of a large diameter at its upper part and an aperture of a small diameter at its lower part respectively is mounted to surround prescribed numbers of LED 3a, on a substrate 3b which has a plurality of LEDs 3a serving as a light source on its upper surface. The colored reflection board 3c reflects light corresponding to the LEDs 3a by an inner surface and an outer surface respectively, and at least one of the inner and outer surfaces is colored as the same color as an emission color (e.g. blue color) of the LEDs 3a. A glove 4 mounted on a light body 2 is formed of a transparent member so as to cover a light source 3 part. Consequently, it is possible to discriminate lamplight because its reflection color becomes an emission color by an outer light reflection even when the lamp 1 is put off, and to contribute an improvement in a long service life and a luminous efficiency of the light source. |
