Description

  The present invention relates to an indicator lamp that displays the position of a transmitter attached to, for example, a fire hydrant box, equipment storage box, or the like.

A generally used indicator lamp is formed of a so-called red globe having a hemispherical top of a cone, and is generally mounted so as to protrude from the mounting surface (for example, Patent Document 1). (See FIGS. 1 and 12).
The reason for projecting the indicator lamp from the mounting surface is to improve the visibility from the side of the mounting surface. On the other hand, there is a risk that the indicator lamp may be damaged by colliding with an object from the side.

Accordingly, the present applicant discloses in Patent Document 2 for the purpose of obtaining an indicator lamp having a low risk of damage due to an external force, such as an object hitting from the outside while ensuring visibility from all directions. An indicator light has been proposed.
The indicator lamp of patent document 2 has a transmitter accommodating part in the center, and the light emission display part is provided in the ring shape so that the outer periphery of this transmitter accommodating part may be enclosed.

And the light emission display part has the inclined surface which inclines inside and the back | inner side, and the front surface of a transmitter is located in the backmost position of an inclined surface.
The reason why the inclined surface is positioned in front of the front surface of the transmitter is to prevent the transmitter from being blocked by the transmitter when viewed obliquely from the side. This is to satisfy the requirement of the law that “the indicator lamp is a red lamp and can be easily identified as being lit from a position 10 m away along a direction that makes an angle of 15 degrees or more with the mounting surface”. .
