Problems solved by technology

[0009] However, in the case of the light-emitting display part having a thin ring-shaped structure like the display lamp described in Patent Document 1, simply increasing the brightness does not necessarily improve the visibility.
In addition, firefighting equipment is connected to multiple terminals, so there is a limit to the current that can be used, and it is difficult to increase the current flowing to the equipment
Due to such limitations, even if the number of light-emitting diodes of the display lamp is increased, the brightness of each LED is only reduced, and the visibility is not improved.

Embodiment approach 1

[0054] In the present embodiment, it is enumerated that the signal transmitter 3 is installed and accommodated on a wall surface 5 such as a casing of a fire hydrant device as an installation surface (see Figure 6 and Figure 7 ) of the display lamp 1 as an example.

[0055] And, below, first, about each structure of display lamp 1, based on Figure 1 to Figure 5 , and appropriately refer to other drawings for detailed description, and then explain the signal transmitter 3 accommodated in the indicator lamp 1 .

[0056] In the following description, when the display lamp 1 is attached to the wall surface 5, the front side of the wall surface 5 is referred to as the front, and the back side of the wall surface 5 is referred to as the rear and the rear.

[0057] 〔Indicator〕

[0058] Such as figure 1 As shown, the indicator lamp 1 has: an outer peripheral wall portion 7 composed of a substantially cylindrical body; a flange-shaped mounting portion 9 protruding outward from t...

Abstract

Disclosed is a display lamp which can improve visibility without increasing the number of light-emitting sources or brightness in a ring-shaped light-emitting display portion. The display lamp (1) of the present invention is a display lamp installed on a wall (5) to display the position of a signal (3) as a disaster prevention facility, and is characterized in that it has a light emitting element (15) for accommodating a light emitting source. The peripheral wall portion (7) and the light emitting display part (11) that transmits the light emitted by the light emitting element (15) to emit light, the light emitting display part (11) is formed in a ring shape, so that the two sides of the light emitting display part are more than the upper and lower sides. The arrangement of the light-emitting elements (15) is set in such a way that the entire part emits light brightly.

Description

technical field [0001] The present invention relates to an indicator lamp for displaying the position of disaster prevention equipment such as a signal transmitter installed in equipment storage boxes such as a fire hydrant box and a multi-panel, for example. Background technique [0002] As an example of a display lamp, for example, Patent Document 1 (Design Registration No. 1460558) discloses "a display lamp comprising: a ring-shaped display lamp main body, and a central portion with a roughly Rectangular-shaped opening, and composed of translucent members colored red; ring-shaped mounting member, which is detachably screwed to the main body of the indicator light and used to install the main body of the indicator light to a fire hydrant storage box, etc.; ring-shaped base plate , sandwiched and fixed between the main body of the display lamp and the mounting member, and install light-emitting diodes (LED lamps) at equal angles, and arrange the light of the light-emitting ...
