Description

  The present invention relates to a light emitter for producing a stop signal from the ground to a train.

  In a conventional railway, a stop signal may be indicated by a hand signal or a fire signal to stop an incoming train. A hand signal indicates a signal when the traffic signal can not be used or when it is not provided (see Article 117 of Non-Patent Document 1). As a hand signal indicating the stop signal, a red flag is used during the day and a red light is used during the night. In order to make it unnecessary to selectively use the red flag and the red light, a light emitting machine having visibility equal to or higher than that of the red flag has been required even in the daytime. The fire signal indicates the stop signal by the red flame of the signal tube. As an alternative to the signal flame tube, a light-emitting machine that emits red light without using a flame has been desired. Such a light emitting machine needs to be able to visually identify the train driver from a distance of 800 m. Moreover, since it uses as a stop signal, a light-emitting machine needs to be distinguishable from general red light sources other than the railway which exists along the way.

  Conventionally, a portable special signal light emitting device in which light emitting diodes are arranged on a panel is known (see Patent Document 1). This portable special signal light-emitting machine needs to be directed to the train accurately, and when the direction is deviated, the visibility is not good.

  There is also known a signal light emitting apparatus in which a light emitting diode is disposed on a substrate and a lens is attached (see Patent Document 2). In this signal light emitter, a lens condenses the light emitted from the light emitting diode in the optical axis direction. For this reason, when using this signal light emitter, it is necessary to more accurately direct it to the train, and when the direction is deviated, the visibility is significantly reduced.

  There is also known an emergency signal lamp in which a plurality of light emitting diodes are arranged in a spiral of one row (see Patent Document 3). Since this emergency signal lamp is disposed in a state where the optical axes of the light emitting diodes are sequentially shifted, the number of light emitting diodes facing the train decreases, and it is difficult to ensure visibility from a distance. Furthermore, this emergency signal light is not easily distinguishable from the general light source other than the railway for the train driver because only a few lights are visible from the train.

  A light emitter according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. This light emitting machine is for showing a stop signal from the ground to the train. As shown in FIG. 1, the light emitting device 1 includes a grip 2 and a light emitting body 3. The gripping unit 2 is a portion held by the user. The light emitter 3 is long and is supported by the grip 2. The longitudinal direction of the elongated light emitter 3 is illustrated by the arrow X.

  As shown in FIG. 2, the light emitter 3 has a plurality of light emitting elements 4a, 4b, 4c. The light emitting elements 4a, 4b, 4c are arranged in a plurality of rows in the longitudinal direction X. The light emitting body 3 is divided into a main light emitting region 5a longest in the longitudinal direction X and auxiliary light emitting regions 5b and 5c shorter than the main light emitting region 5a. Each of the light emitting elements 4a, 4b, 4c has a light distribution characteristic having directivity in the optical axis direction, and the optical axis is directed in the direction orthogonal to the longitudinal direction X. That is, the optical axis is directed in the radial direction with respect to the longitudinal direction X.

  As shown in FIG. 3, in the main light emitting region 5a, the optical axes 41a of the plurality of light emitting elements 4a are directed in the same direction.

  As shown in FIG. 4, the light emitting element 4b is disposed in the auxiliary light emitting area 5b. In the light emitting element 4b, a predetermined deflection angle θ of less than 90 degrees with respect to the optical axis 41a in the main light emitting region 5a is set to the optical axis 41b.

  As shown in FIG. 5, the light emitting element 4c is disposed in the auxiliary light emitting region 5c. In the light emitting element 4c, a declination angle -θ that is opposite in sign to the declination angle θ is set to the optical axis 41c.

  The main light emitting region 5a is a substantially rectangular shape long in the longitudinal direction X (see FIG. 2). The auxiliary light emitting areas 5b and 5c are rectangular. The width of the rectangle is approximately the same as that of the main light emitting region 5a. Note that the substantially rectangular shape does not have to be a mathematically strict rectangular shape, and is a shape that substantially allows light emission to appear rectangular. The substantially rectangular shape does not have to be a mathematically strict rectangular shape, and is a shape that substantially allows light emission to be seen as a rectangular shape.

  The auxiliary light emitting areas 5b and 5c are divided into a rectangular first auxiliary light emitting area 5b and a rectangular second auxiliary light emitting area 5c. In the first auxiliary light emitting area 5b, the optical axis 41b of the light emitting element 4b is set to a predetermined deflection angle θ of less than 90 degrees with respect to the optical axis 41a of the main light emitting area 5a (see FIG. 4). In the second auxiliary light emitting area 5c, the optical axis 41c of the light emitting element 4c is an angle of deviation from the optical axis 41a of the main light emitting area 5a that is opposite to the angle θ of the first auxiliary light emitting area 5b. θ is set (see FIG. 5).

  The light emitting elements 4a, 4b and 4c are red light emitting diodes that emit red light (see FIG. 1).

  In the light emitting device 1, a battery 6 for supplying electric power to the light emitting elements 4 a, 4 b and 4 c is accommodated in the grip portion 2.

  Each configuration of the light emitting device 1 will be described in more detail. The light emitting device 1 has a substantially cylindrical shape, and the grip portion 2 is on the base end side, and the light emitting body 3 is on the tip end side. In the light emitting device 1, the light emitting body 3, the lighting circuit for lighting the light emitting body 3, and the battery 6 are accommodated in a hollow case 7 having a substantially cylindrical outer shape. In the case 7, the part covering the light emitting body 3 has translucency. The light emitting device 1 is dustproof and waterproof by a case 7.

  The light emitter 3 has a substrate 31 and light emitting elements 4a, 4b and 4c disposed on the substrate 31 (see FIG. 2). The substrate 31 has a flat plate shape.

  Since the light emitting elements 4a, 4b and 4c have light distribution characteristics having directivity in the optical axis direction, the luminous intensity in the direction decreases as the angle with respect to the optical axis direction increases. For example, when the luminous intensity in the optical axis direction of the light emitting elements 4a, 4b and 4c is 100%, the luminous intensity in the direction of 30 degrees with respect to the optical axis is about 20%.

  In the main light emitting region 5a, the light emitting element 4a is disposed with the optical axis 41a perpendicular (normal direction) to the substrate 31 (see FIG. 3). In the first auxiliary light emitting area 5b, the light emitting element 4b is disposed with the optical axis 41b inclined by an angle θ with respect to the substrate 31 (see FIG. 4). In the second auxiliary light emitting area 5c, the light emitting element 4c is disposed so that the optical axis 41c is inverted with respect to the substrate 31 (see FIG. 5). The argument θ is, for example, 30 degrees. In addition, in FIGS. 3-5, the elongate direction X of the light-emitting body 3 is a direction orthogonal to the paper surface where the figure was drawn.

  As a modification, the auxiliary light emitting area is not divided into the first auxiliary light emitting area 5b and the second auxiliary light emitting area 5c, but a plurality of light emitting elements 4b and 4c having different tilting directions are mixed in one auxiliary light emitting area. It may be arranged. Further, as another modification, the substrate 31 is divided into three for each light emitting area 5a, 5b, 5c, and the optical axes 41a, 41b, 41c of all the light emitting elements 4a, 4b, 4c are perpendicular to the substrate 31 It is also possible to set the declination angles θ and −θ to the optical axes 41 b and 41 c by setting the declination angles θ and −θ to the substrate 31 of each of the auxiliary light emitting regions 5 b and 5 c.

  The light emitting machine 1 has a switch 8 (see FIG. 1). The switch 8 is a push button switch. When the switch 8 is pressed, the lighting circuit switches the light-emitting body 3 between constant lighting, blinking and extinguishing. The lighting circuit is provided, for example, on the back side of the substrate 31 or in the grip portion 2. The switch 8 is surrounded by a cylinder 81, which is prevented by this cylinder 81 from being pushed accidentally.

  The light emitting device 1 has a magnet 9 on the proximal end side of the grip 2. When the light emitting machine 1 is placed on the rail, the magnet 9 is attracted to the rail to prevent the light emitting machine 1 from falling.

  An example of how to use the light emitting device 1 configured as described above will be described. The user holds the light emitter 1 with one hand and stands on the ground with the front of the body facing in the direction of the coming train. The user causes the light emitting machine 1 to emit light, raises the hand holding the light emitting machine 1 to the side, and directs the main light emitting area 5 a of the light emitting body 3 to the train. The user shakes the light emitting machine 1 in a plane parallel to the sleepers. At this time, the tip end of the light emitting machine 1 swings between a substantially horizontal direction and a vertically upward direction. The light emission of the light emitting machine 1 is always on or blinking.

  Another example of how to use the light emitting machine 1 will be described. The user causes the light emitting machine 1 to emit light, and the base end side of the holding unit 2 is directed downward to the rail, and the main light emitting area 5 a of the light emitting body 3 is directed to the coming train. That is, the optical axis 41a of the light emitting element 4a disposed in the main light emitting area 5a is directed to the head of a train that almost arrives.

  As described above, according to the light emitting device 1 according to the present embodiment, since the light emitting body 3 has the plurality of light emitting elements 4a, 4b and 4c arranged in a plurality of rows, the luminous intensity is increased, and visibility from a distance is secured. Ru. The optical axes 41b and 41c of the light emitting elements 4b and 4c disposed in the auxiliary light emitting areas 5b and 5c are orthogonal to the longitudinal direction X of the light emitting body 3 and are on the optical axis 41a of the light emitting element 4a of the main light emitting area 5a. On the other hand, since the deflection angles θ and −θ are set, the light intensity of the auxiliary light emitting regions 5b and 5c compensates for the light intensity even if the direction of the main light emitting region 5a deviates, and the visibility is secured. In addition, since the light emitter 3 is long, it is easy to distinguish it from light sources other than railways, and it is easier for the user to hold the grip 2 and shake the light emitter 1 to make the distinction easier. .

  Since the main light emission area 5a is substantially rectangular long in the longitudinal direction X and the auxiliary light emission areas 5b and 5c are substantially rectangular, the light emission shape looks long from a distance, and it is easy to distinguish from light sources other than railways It is.

  The auxiliary light emission areas 5b and 5c are divided into a rectangular first auxiliary light emission area 5b and a rectangular second auxiliary light emission area 5c, and the light emission angle of the optical axis is the same in each auxiliary light emission area. Production of body 3 is easy.

  Since the light emitting elements 4a, 4b and 4c are red light emitting diodes that emit red light, the light emitting apparatus 1 can display a red stop signal, and the visibility is improved by using a high brightness light emitting diode. can do.

  Since the battery that supplies power to the light emitting elements 4a, 4b, and 4c is accommodated in the grip portion 2, the center of gravity of the light emitting device 1 is close to the hand, and the user can easily hold the light emitting device 1.

  The present invention is not limited to the configuration of the embodiment described above, and various modifications can be made without departing from the scope of the invention. For example, the switch 8 is not limited to a push button switch, and may be a slide switch. The light emitting elements 4a, 4b, and 4c are not limited to light emitting diodes, and may be, for example, discharge light emitting elements.
