Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an indicator lamp whose visibility is high, and which can be manufactured at low cost.SOLUTION: An indicator lamp 1 radiates light in a radial manner separating from a center axis C toward the periphery of the center axis C. The indicator lamp 1 has: a base member 3; a plurality of light-emitting diodes 5 supported by the base member 3 and arranged annularly around the center axis C at an equal interval so as to emit light in a radial manner separating from the center axis C toward the periphery of the center axis C; and a plurality of lenses 6 supported by the base member 3 and arranged annularly around the center axis C so as to face a main light-emitting direction X of the plurality of light-emitting diodes 5 respectively. Each lens 6 has a center part 11 and both end parts 12, and these have a light distribution width expansion function for expanding light distribution width in a circumferential direction R by guiding incident light from the light-emitting diode 5 in a direction separating from the main light-emitting direction X to the circumferential direction R.SELECTED DRAWING: Figure 1
