Embodiments for Carrying Out the Invention

[0013] Hereinafter, an example of an embodiment of the indicator lamp of the present invention will be described as the indicator lamp 1 with reference to FIGS. 1 to 5. The indicator lamp of the present invention can be used as an indicator lamp for various disaster prevention facilities such as an indicator lamp for an emergency warning facility, an indicator lamp for an automatic fire alarm facility, and an indicator lamp for a fire hydrant facility.

[0014] Here, the terms indicating directions and positions such as "up", "down", "left", "right", "front", "rear", "vertical", and "horizontal" used to describe this invention are based on the directions and positions in the state when the indicator light is installed.

[0015] [Entire device] The indicator light 1 includes a cover (globe) 2 and a main body 3 to which the cover 2 is attached on the front side.

[0016] ·Light-emitting display section The cover 2 has a light-emitting display section 2a that is circular in shape when viewed from the front and is provided with its front side exposed to the outside. The light-emitting display section 2a has translucency and emits light using an LED element 5 (an example of a light-emitting element) provided on the rear side as a light source, which will be described later.

[0017] The indicator light 1 is used, for example, by being attached to the front surface of a disaster prevention device or the like. More specifically, it is used by being attached to the front surface of a disaster prevention device or the like with the front side of the light-emitting display section 2a exposed to the outside.

[0018] Note that the light-emitting display section 2a is assumed to have a substantially flat front surface, but it may also have a shape that protrudes forward.

[0019] ·Main body Inside the main body 3, an LED element 5 or the like that serves as the light source of the light-emitting display section 2a is provided.

[0020] ·Front panel Note that in the case of the illustrated example, the indicator light 1 further includes a front panel 4. The front panel 4 has an opening 4a that exposes the light-emitting display section 2a of the cover 2 to the outside, and is attached to the front side of the main body 3 while sandwiching the cover 2 between the main body 3.

[0021] [Light-emitting element, light-emitting element group] ·LED element The indicator light 1 has a plurality of LED elements 5 (an example of a light-emitting element) that serve as the light source of the light-emitting display section 2a.

[0022] ·LED element substrate The LED element 5 is provided in a state of being mounted on an LED element substrate 6 (an example of a light-emitting element substrate) described later.

[0023] ·LED element group The plurality of LED elements 5 are provided by being grouped into a plurality of LED element groups (an example of a light-emitting element group). Note that the number of LED elements 5 in each group can be one or more.

[0024] ·Partitioned arrangement, block turning off The plurality of LED element groups are provided with a circuit configuration capable of maintaining the lighting state of the LED elements 5 in group units (for example, the LED elements 5 within a group are connected in series, and the groups are connected in parallel or via a bypass circuit), and are provided with positions partitioned in group units (for example, LED element groups L1 to L4 described later). Therefore, when a failure occurs in the LED element 5 or the like, the LED element 5 will turn off in units of the partition of the LED element group.

[0025] Thereby, it is possible to make it easier to notice a failure in the LED element 5 or the like.

[0026] ·Grouping corresponding to the area of the light-emitting display section More specifically, the plurality of LED element groups are provided by being grouped corresponding to the area of the light-emitting display section 2a (for example, the areas of R1 to R4 described later). Therefore, when a failure occurs in the LED element 5 or the like, the LED element 5 will turn off in units of the area of the light-emitting display section 2a.

[0027] Also by this, it is possible to make it easier to notice a failure in the LED element 5 or the like.

[0028] Further, even if the LED element 5 of the LED element group corresponding to a part of the area of the light-emitting display section 2a turns off due to a failure of the LED element 5 or the like, the lighting state of the LED element 5 of the LED element group corresponding to the other area is maintained, so that the function as an indicator light can be maintained.

[0029] Therefore, in the indicator lamp 1, while maintaining the function as an indicator lamp, it is possible to easily notice a failure in the LED element 5 or the like.

[0030] As an aspect of grouping the plurality of LED element groups corresponding to the regions of the light-emitting display portion 2a, for example, it can be divided into at least two LED element groups corresponding to at least two regions of the light-emitting display portion 2a (for example, two divisions left and right with the vertical center line as a boundary, or two regions divided up and down with the horizontal center line as a boundary).

[0031] If it is grouped in such a manner, even if the LED elements 5 in a part of the region of the light-emitting display portion 2a are turned off due to a failure of the LED element 5 or the like, the lighting state of the LED elements 5 in at least another 1 / 2 region of the light-emitting display portion 2a (for example, 1 / 2 region in the case of two divisions, 2 / 3 region in the case of three divisions, 3 / 4 region in the case of four divisions) can be maintained. That is, the function as an indicator lamp can be maintained.

[0032] ·Arrangement aspect of the LED element substrate ··Multiple sheets arranged, separated arrangement The LED element substrate 6 may be provided with all the LED elements 5 on one substrate, or may be provided divided into a plurality of sheets. The number of sheets can be an appropriate number according to the number of LED element groups, the number of regions of the light-emitting display portion 2a, etc. For example, when dividing a plurality of LED element groups into two groups corresponding to the left and right or upper and lower regions of the light-emitting display portion 2a, the LED element substrate 6 can be divided into two sheets and provided separated left and right or up and down on the back side of the light-emitting display portion 2a.

[0033] ··Inclined arrangement Further, the LED element substrate 6 may be provided on the back side of the light-emitting display portion 2a such that the mounting surface of the LED element 5 is parallel (vertically standing) or perpendicular (lying flat) to the front direction of the light-emitting display portion 2a. However, it may also be provided such that the mounting surface of the LED element 5 is inclined left and right or up and down with respect to the front direction of the light-emitting display portion 2a. For example, when the LED element substrate 6 is divided into two sheets corresponding to the left and right or up and down regions in the front view of the light-emitting display portion 2a and the LED element groups are grouped, it can be provided on the back side of the light-emitting display portion 2a so as to be separated left and right or up and down while being inclined left and right or up and down with respect to the front direction of the light-emitting display portion 2a.

[0034] ·Specific examples of grouping of LED elements and arrangement of LED element substrates In the case of the illustrated example, the LED element groups are provided by being divided into four groups L1 to L4 (see FIG. 3). The LED element groups L1 to L4 are divided left and right by two LED element substrates 6 separated left and right (see FIG. 2), and are provided by being divided left and right, and in each of the two LED element substrates 6, they are provided by being divided up and down. And the LED element groups L1 to L4 are provided corresponding to four regions R1 to R4 (see FIG. 1) that are four-divided into the upper, lower, left, and right of the light-emitting display portion 2a. That is, the LED element group L1 is provided corresponding to the region R1 in the upper left portion in the front view, the LED element group L2 is provided corresponding to the region R2 in the lower left portion in the front view, the LED element group L3 is provided corresponding to the region R3 in the upper right portion in the front view, and the LED element group L4 is provided corresponding to the region R4 in the lower right portion in the front view (see FIGS. 1 and 3). Incidentally, as will be described later, as shown in FIG. 2, the light of the LED element substrate 6 is irradiated with the light inclined from one side to the other side of the left and right in the front view of the light-emitting display portion 2a.

[0035] For example, when the LED element 5 in the LED element group L1 is turned off due to a failure of the LED element 5 or the like, the LED element 5 in the LED element group L1 is turned off in units of the region R1 in the upper left region of the corresponding light emitting display unit 2a. On the other hand, in the lower left region R2, the upper right region R3, and the lower right region R4 other than the upper left region R1 in the off state, the lighting state of the LED element 5 is maintained. That is, the lighting state of 3 / 4 of the region of the light emitting display unit 2a is maintained.

[0036] Therefore, in the indicator lamp 1, as described above, it is possible to easily notice a failure in the LED element 5 or the like while maintaining the function as an indicator lamp.

[0037] Furthermore, in the case of the illustrated example, two LED element substrates 6 are provided separately on the left and right on the back side of the light emitting display unit 2a (see FIG. 2). The two LED element substrates 6 are provided such that the mounting surface of the LED element 5 is inclined in the left-right direction with respect to the front direction of the light emitting display unit 2a so that light can be irradiated obliquely from one side of the left and right of the light emitting display unit 2a toward the other side of the left and right (see FIG. 2). Among the two LED element substrates 6, the LED element 5 of the LED element groups L1 and L2 corresponding to the upper left region R1 and the lower left region R2 of the light emitting display unit 2a when viewed from the front is provided on the LED element substrate 6 located on the right side when viewed from the front (see FIG. 3(b)), and the LED element 5 of the LED element groups L3 and L4 corresponding to the upper right region R3 and the lower right region R4 of the light emitting display unit 2a when viewed from the front is provided on the LED element substrate 6 located on the left side when viewed from the front (see FIG. 3(a)).

[0038] In order to make each LED element group correspond to each area of the light-emitting display section 2a, it is necessary to make the light distribution of each LED element group correspond to each area of the corresponding light-emitting display section 2a. If the two LED element substrates 6 are provided in the inclined arrangement as described above, by changing the inclination angles of the two LED element substrates 6, the angular range of the light distribution in the left-right direction of the LED element groups provided on each of them can be changed. Therefore, in terms of design, for the left and right areas of the light-emitting display section 2a (the upper left area R1 and the lower left area R2 in the front view, or the upper right area R3 and the lower right area R4 in the front view), it is possible to make it easier to make the light distributions of the LED element groups (LED element groups L1 and L2, or LED element groups L3 and L4) provided on each of the two LED element substrates 6 correspond.

[0039] · Inclination angle adjustment means for the light-emitting element substrate Angle adjustment means for making the inclination angle of the LED element substrate 6 adjustable can be further provided. By providing such angle adjustment means, the angular range of the light distribution in the left-right direction of the LED element group can be adjusted, and the light distribution can be adjusted so as to correspond to the left and right areas of the light-emitting display section 2a (the upper left area R1 and the lower left area R2 in the front view, or the upper right area R3 and the lower right area R4 in the front view). Also, according to the installation environment of the indicating lamp 1, the angular range of the light distribution in the left-right direction can be adjusted.

[0040] The angle adjustment means can be an angle adjustment bracket or a torque hinge for fixing the LED element substrate 6 so that its angle can be adjusted, or it can be a shim (spacer) or the like that is inserted into and removed from the fixing portion of the LED element substrate 6.

[0041] · Luminance adjustment means for each group Luminance adjustment means for adjusting the luminance of the LED elements 5 in units of the LED element groups can be further provided. By providing such luminance adjustment means, the brightness can be adjusted in units of the areas of the light-emitting display section 2a, and according to the installation environment of the indicating lamp 1, the brightness of each area of the light-emitting display section 2a can be adjusted.

[0042] The light intensity adjustment means can be a variable resistor or the like provided on the LED element substrate 6.

[0043] · Lighting control in group units The lighting of the LED element 5 may be controlled in units of groups of the LED element group, so that the lighting may be controlled in units of regions of the light emitting display unit 2a. For example, in the case of the illustrated example, the lighting of the LED element 5 may be controlled in units of groups of the LED element groups (LED element groups L1 and L2, or LED element groups L3 and L4) provided on each of the two LED element substrates 6, so that the lighting may be controlled in units of regions of the light emitting display unit 2a.

[0044] [Example of application to tunnel disaster prevention equipment] The indicator lamp 1 can be used as an indicator lamp for tunnel disaster prevention equipment (such as a fire hydrant box or a fire extinguisher box). FIG. 5 shows an example in which it is used as an indicator lamp for a fire hydrant box 10 for a tunnel.

[0045] The fire hydrant box 10 houses a fire hose or the like in the housing, and is installed on the side of the road (such as an inspection road) with the front side facing the road side. The indicator lamp 1 is provided on the front surface of the housing of the fire hydrant box 10 in a state where the light emitting display unit 2a faces forward (road side) and is exposed to the outside.

[0046] In the case of an indicator lamp provided on disaster prevention equipment installed on the side of a tunnel road, it is necessary to improve the visibility from vehicles traveling on the road, that is, the visibility from the side.

[0047] If the indicator lamp 1 is grouped as shown in the illustrated example corresponding to four regions obtained by dividing the LED element group into four regions above, below, left, and right of the light emitting display unit 2a, even if any region of the light emitting display unit 2a goes out due to a failure of the LED element 5 or the like, the visibility from the side of the indicator lamp 1 can be ensured by the other regions that maintain the lighting state.

[0048] In addition, if the indicator light 1 is provided with an angle adjustment means for adjusting the inclination angle of the LED element substrate 6, the angular range of the light distribution in the left-right direction can be adjusted according to the conditions of the installation location such as the curve of the tunnel, and the visibility from the side can be improved.

[0049] Furthermore, if the indicator light 1 is provided with a luminous intensity adjustment means for the LED elements 5 in the group unit of the LED element group, the brightness can be adjusted in the unit of the area of the light-emitting display part 2a according to the conditions of the installation location such as the lighting of the tunnel and the curve. For example, by adjusting so that the left and right areas become particularly bright, the visibility from the side of the indicator light 1 can be improved.

[0050] [Example of configuration change] The embodiments of the present invention have been described above with reference to the drawings. However, the specific configuration is not limited to the above embodiments, and includes design changes and the like within the scope not departing from the gist of the present invention.
