[0004] However, the indicator lamp disclosed in Patent Document No. 1 has a problem in that a large number of light emitting elements are required and the power consumption is also large. An object of the present invention is to provide an indicator lamp capable of improving the light irradiation efficiency and an indicator lamp set including the same.

Means for Solving the Problems

[0005] The indicator light according to the present invention comprises a plurality of light-emitting units and a control means, each of the plurality of light-emitting units having a light source, a reflecting unit that reflects light emitted from the light source toward a first direction, a first lens unit that transmits the light reflected by the reflecting unit and diffuses it toward a second direction perpendicular to the first direction, and a second lens unit that transmits the light reflected by the reflecting unit and diffuses it toward a third direction perpendicular to the first and second directions, the plurality of light-emitting units include at least a first light-emitting unit and a second light-emitting unit, the first light-emitting unit is offset from the second light-emitting unit in the second and third directions, and the control means alternately flashes the light source of the first light-emitting unit and the light source of the second light-emitting unit.

[0006] The indicator light comprises a housing in which the reflector portion is integrally formed, and an outer lens provided with the first lens portion and the second lens portion, wherein the outer lens preferably covers the opening of the housing.

[0007] The indicator light set according to the present invention comprises an indicator light and a support base to which the indicator light is detachably mounted, wherein a first magnet is provided on either the indicator light or the support base, and a second magnet or metal member is provided on the other of the indicator light or the support base, the indicator light is mounted on the support base by the magnetic force between the first magnet and the second magnet or metal member, the indicator light is provided with a screw hole, and the indicator light is fixed to the support base by screwing a handle screw inserted through the support base into the screw hole. [Effects of the Invention]

[0008] According to the indicator light of the present invention, each of the first light-emitting unit and the second light-emitting unit is equipped with first and second lens units that diffuse the light reflected by the reflector unit in a second and third direction, respectively, so that light spreading in a cross shape is emitted from the first and second light-emitting units. Furthermore, since the first light-emitting unit is offset from the second light-emitting unit in the second and third directions, by installing and using the indicator light so that the second and third directions are horizontal and vertical (or vertical and horizontal), respectively, the illumination range of the light emitted by the first and second light-emitting units can be expanded in the horizontal and vertical directions. In addition, since the light emitted from the light source is reflected toward the first direction and then diffused toward the second or third direction for illumination, the light illumination efficiency can be improved, the number of light sources can be reduced without sacrificing visibility from a distance, and the indicator light can be made smaller, lighter, and more energy-efficient. Furthermore, since the control means alternately flashes the light source of the first light-emitting unit and the light source of the second light-emitting unit, power consumption can be suppressed compared to when they are flashed simultaneously.

[0009] Furthermore, since the reflective portion is integrally formed with the housing, the number of parts can be reduced compared to the case where the housing and the reflective portion are constructed as separate components.

[0010] The indicator light set according to the present invention comprises an indicator light and a support base to which the indicator light is detachably mounted, and thus can achieve the same effects as described above. Furthermore, a first magnet is provided on either the indicator light or the support base, and a second magnet or metal member is provided on the other of the indicator light or the support base. The indicator light is attached to the support base by the magnetic force between the first magnet and the second magnet or the metal member, and the indicator light is fixed to the support base by screwing a handle screw inserted through the support base into a screw hole provided in the indicator light, thus making it easy to attach the indicator light to the support base.

[Figure 7] Figure 1 is an exploded perspective view showing the support base of the indicator light set. [Modes for carrying out the invention]

[0012] The following describes an indicator light set according to an embodiment of the present invention with reference to the attached drawings. Referring to Figure 1, the indicator light set 100 according to this embodiment is used, for example, to inform vehicle drivers that construction is underway during road construction or railway construction, and comprises an indicator light 1 and a support base T on which the indicator light 1 is detachably mounted. The indicator light 1 has four light-emitting parts 10 (first to fourth light-emitting parts 10A to 10D), and light is emitted from each light-emitting part 10 in a cross shape. In the first mode, the first light-emitting part 10A and the second light-emitting part 10B flash alternately in yellow, and in the second mode, the third light-emitting part 10C and the fourth light-emitting part 10D flash alternately in red. The following describes this in detail.

[0013] Referring to Figures 2 and 3, the indicator light 1 comprises a housing 2, a pair of LED boards 3 (3A, 3B), a control board 4, an outer lens 5, a lens cover 6, and a housing cover 7.

[0014] The housing 2 is a box-shaped metal member with an open front, and has a pair of left and right housing sides 2A and 2B, a housing upper part 2C, a housing lower part 2D, and a housing base 2E, which are integrally formed.

[0015] Referring also to Fig. 4, the pair of left and right housing side portions 2A and 2B are symmetric about an axis extending in the vertical direction D3 (symmetric about the horizontal direction D2), and four concave reflecting surfaces 21a to 21d are provided in a row in the vertical direction D3 on the inner surface of the housing side portion 2A, and four concave reflecting surfaces 21e to 21h are provided in a row in the vertical direction D3 on the inner surface of the other housing side portion 2B. In the present embodiment, each of the reflecting surfaces 21a to 21h is a semi-parabolic reflecting surface (semi-parabolic mirror), and has a shape in which a parabolic surface that expands concentrically forward in the D1 direction from the rear end portion is bisected in the horizontal direction D2 along the center line.

[0016] The LED substrates​​​​​​​​​​​Referring to FIGS. 3 and 5, the outer lens 5 is transparent and covers the front opening of the housing 2. As shown in FIG. 6, the outer lens 5 is provided with eight lens portions 51 (51A to 51H), and these lens portions 51A to 51H respectively correspond to the eight reflecting surfaces 21a to 21h shown in FIG. 3.

[0020] The lens portion 51A has a plurality of cylindrical lenses 52a extending parallel to each other. Similarly, the lens portions 51B to 51H each have a plurality of cylindrical lenses 52b to 52h extending parallel to each other. These cylindrical lenses 52a to 52h are formed on the back surface (inner surface) of the outer lens 5. Hereinafter, when explaining without distinguishing the cylindrical lenses 52a to 52h, they will simply be referred to as cylindrical lenses 52.

[0021] In the present embodiment, the lens direction of the cylindrical lenses 52 included in the lens portions 51A, 51C, 51E, and 51G (the longitudinal direction of the cylindrical lenses 52a, 52c, 52e, and 52g) is the vertical direction D3. In other words, in each of the lens portions 51A, 51C, 51E, and 51G, a plurality of cylindrical lenses 52 are arranged in parallel in the horizontal direction D2.

[0022] On the other hand, the lens direction of the cylindrical lenses 52 included in the lens portions 51B, 51D, 51F, and 51H (the longitudinal direction of the cylindrical lenses 52b, 52d, 52f, and 52h) is the horizontal direction D2. In other words, in each of the lens portions 51B, 51D, 51F, and 51H, a plurality of cylindrical lenses 52 are arranged in parallel in the vertical direction D3.

[0023] Also, as shown in FIG. 3, on the surface of the outer lens 5, a pair of upper and lower mounting recesses 50a and 50b are provided at the central portion 5A in the horizontal direction D2, and recesses 50c are provided on both sides thereof. The cylindrical lens 52 is provided on the back surface side of the recess 50c. Also, the central portion 5A of the surface of the outer lens 5 is slightly convex-arc-shaped in plan view.

[0024] In this configuration, a portion of the light emitted from each LED 32 is reflected by the corresponding reflective surface 21 toward the front D1 (corresponding lens portion 51) to become parallel light, which is then refracted by the lens portion 51 and projected outwards. At this time, the direction of refraction of light by the lens portion 51 is perpendicular to the lens direction. That is, the lens portions 51A, 51C, 51E, and 51G refract the light in the lateral direction D2 and transmit it to the outside, so that the light that has passed through the lens portions 51A, 51C, 51E, and 51G spreads radially in the lateral direction D2 when viewed from the front and moves toward the front D1 in a planar manner. On the other hand, the lens portions 51B, 51D, 51F, and 51H refract the light in the vertical direction D3 and transmit it to the outside, so that the light that has passed through the lens portions 51B, 51D, 51F, and 51H spreads radially in the vertical direction D3 when viewed from the front and moves toward the front D1 in a planar manner.

[0025] Each of the light-emitting sections 10A to 10D (Figure 1) described above is composed of a light source consisting of a pair of LEDs 32, a reflective section consisting of a pair of reflective surfaces 21, and a pair of lens sections 51.

[0026] Specifically, as shown in Figure 4, the first light source L1 is composed of a pair of LEDs 32a and 32b, the second light source L2 is composed of a pair of LEDs 32g and 32h, the third light source L3 is composed of a pair of LEDs 32e and 32f, and the fourth light source L4 is composed of a pair of LEDs 32c and 32d.

[0027] Furthermore, as shown in Figure 3, the first reflective section R1 is formed by a pair of reflective surfaces 21a and 21b, the second reflective section R2 is formed by a pair of reflective surfaces 21g and 21h, the third light source R3 is formed by a pair of reflective surfaces 21e and 21f, and the fourth reflective section R4 is formed by a pair of reflective surfaces 21c and 21d.

[0028] The first light-emitting section 10A is composed of a first light source L1, a first reflector R1, and a pair of lens sections 51A and 51B, and the second light-emitting section 10B is composed of a second light source L2, a second reflector R2, and a pair of lens sections 51G and 51H. Similarly, the third light-emitting section 10C is composed of a third light source L3, a third reflector R3, and a pair of lens sections 51E and 51F, and the fourth light-emitting section 10D is composed of a fourth light source L4, a fourth reflector R4, and a pair of lens sections 51C and 51D.

[0029] The control board 4 (Figure 3) is housed and held in the housing space S1 (Figure 4) of the housing 2 and includes control means (not shown) for controlling the lighting of each LED 32. In the first mode, the control means alternately flashes the first light source L1 and the second light source L2, and in the second mode, it alternately flashes the third light source L3 and the fourth light source L4.

[0030] Here, the color of the light emitted from the first light source L1 and the second light source L2 (i.e., LEDs 32a, 32b, 32g, 32h) is different from the color of the light emitted from the third light source L3 and the fourth light source L4 (i.e., LEDs 32e, 32f, 32c, 32d). In this embodiment, the first light source L1 and the second light source L2 emit yellow light, and the third light source L3 and the fourth light source L4 emit red light.

[0031] Therefore, in the first mode, yellow flashing light is emitted from the first light-emitting unit 10A and the second light-emitting unit 10B, and in the second mode, red flashing light is emitted from the third light-emitting unit 10C and the fourth light-emitting unit 10D.

[0032] The lens cover 6 is a rectangular rubber member when viewed from the front, and has a pair of upper and lower protrusions 6a and 6b projecting backward from its central portion. The protrusions 6a and 6b are fitted into mounting recesses 50a and 50b on the outer lens 5, thereby attaching it to the outer lens 5. The width of the lens cover 6 is smaller than the width of the outer lens 5, so that the lens cover 6 covers the central portion of the front surface of the outer lens 5 in the width direction D2 (the portion corresponding to the housing space S1), while the front surface of the outer lens 5 on both sides in the width direction D2 (where the lens portion 51 is provided) remains exposed to the outside. The thickness of the lens cover 6 gradually increases towards the center in the width direction D2, and its front surface 61 is in the shape of a protruding circular arc when viewed from above.

[0033] The housing cover 7 is made of rubber and is attached to the housing 2, covering the periphery and part of the back surface of the housing 2. The housing cover 7 also has at least one hook-and-loop fastener 70 (one side of the hook-and-loop fastener) attached to it (four in the example in Figure 2), and by engaging the hook-and-loop fastener (the other side of the hook-and-loop fastener) attached to the GPS tag (not shown) with one of the hook-and-loop fasteners 70, the GPS tag can be attached to the indicator light 1 (housing cover 7 of the indicator light 1).

[0034] The indicator light 1 is further equipped with a battery B (Figure 3), and as shown in Figure 2(b), the back side of the indicator light 1 is provided with a charging connector CN for the battery B, a power button B1, and an illumination button B2. The battery B is, for example, a lithium-ion battery and is housed and held in the housing space S1 of the housing 2. In this embodiment, a USB type C connector is used as the charger connector CN. Conventional indicator lights are generally AC 100V rechargeable, and charging at the work site was not easy, but by using a USB type C connector for the charger connector CN, the battery B can be charged using a USB terminal or car charger provided in a vehicle such as a work vehicle, making charging at the work site easier.

[0035] Referring to Figure 3, the indicator light 1 is further equipped with mounting means that enable attachment to the support base T shown in Figure 7, the mounting means having a pair of magnets (first magnets) 8 provided on the lower surface of the housing 2 (outer surface of the lower housing portion 2D) and a screw hole 7b provided on the lower part of the back surface of the housing 2 (back surface of the housing base portion 2E), the pair of magnets 8 are exposed to the outside through a notch 7a provided in the housing cover 7.

[0036] Referring to Figure 7, the support base T comprises a support body T1 and an attachment T2 detachably mounted on the top of the support body T1. The support body T1 is, for example, a tripod with a ball head, and the attachment T2 comprises a base portion T21, an upright portion T22 that rises from the side edge of the base portion T21, a pair of magnets (second magnets) T23 fixed to the upper surface of the base portion T21, and a handle screw T24. The upright portion T22 is provided with an insertion hole T22a through which the threaded portion T24a of the handle screw T24 is inserted. The base portion T21 is also provided with insertion holes T21a (four insertion holes 21a in the example of Figure 6), and the attachment T2 is attached to the support body T1 by screwing a screw (not shown) inserted through the insertion holes T21a into a female threaded portion T1a provided on the top of the support body T1.

[0037] To attach the indicator light 1 to the support base T, first the indicator light 1 is placed on the base portion T21 of the support base T. Then, the magnet 8 on the indicator light 1 and the magnet T23 on the support base T attract each other, and the indicator light 1 is positioned and attached to the predetermined position on the support base T. Next, the threaded portion T24a of the handle screw T24, which is inserted through the insertion hole T22a of the upright portion T22, is screwed into the screw hole 7b (Figure 2(b)) provided on the back side of the indicator light 1. This fixes the indicator light 1 to the support base T.

[0038] Furthermore, the number of magnets 8 on the indicator light 1 is not limited to two; it may be one or three or more. Similarly, the number of magnets T21 on the support base T is not limited to two; it may be one or three or more. In addition, the same effect as described above can be obtained by making either the magnet 8 on the indicator light 1 or the magnet T21 on the support base T a metal component. That is, a magnet can be provided on either the indicator light 1 or the support base T, and another magnet or metal component can be provided on the other of the indicator light 1 or the support base T, so that the indicator light 1 is positioned and attached to the support base T by the magnetic force between the magnet and the other magnet or metal component.

[0039] Next, the method of use and effects of indicator light 1 will be explained. First, the user attaches indicator light 1 to the support base T as described above, and then places the support base T with indicator light 1 attached in the desired location. Next, the user presses the power button B1, and then the light button B2, which sets indicator light 1 to the first mode, and the control means makes the first light source L1 and the second light source L2 blink alternately.

[0040] At this time, the yellow light emitted from the pair of LEDs 32a and 32b constituting the first light source L1 is reflected forward D1 by the corresponding reflective surfaces 21a and 21b, becoming parallel light, which is then transmitted through the lens sections 51A and 51B and diffused. The light transmitted through lens section 51A is diffused in the horizontal direction D2 when viewed from the front, and the light transmitted through lens section 51B is diffused in the vertical direction D3 when viewed from the front. As a result, the light emitted from the first light-emitting section 10A is diffused in a cross shape overall. Similarly, the light emitted from the second light-emitting section 10B is also diffused in a cross shape overall. By diffusing the light in a cross shape in this way, the visibility (illuminance) of the light at a distance can be improved compared to when the light is diffused in all directions.

[0041] Furthermore, since the cylindrical lenses 52a to 52h are formed on the back surface (inner surface) of the outer lens 5, compared to when they are formed on the front surface (outer surface) of the outer lens 5, they can refract more light and increase the angle of light spread, thereby expanding the light illumination range.

[0042] Furthermore, since the first light-emitting unit 10A and the second light-emitting unit 10B are positioned diagonally opposite each other (i.e., the first light-emitting unit 10A is offset from the second light-emitting unit 10B by a vertical D3 and a horizontal D2), the light illumination range can be expanded in the vertical D3 (up and down direction) and horizontal D2 (horizontal direction) compared to when light is irradiated from either one. In other words, since the first light-emitting unit 10A is offset from the second light-emitting unit 10B by a vertical D3, the light illumination range from the first and second light-emitting units 10A and 10B is expanded in the vertical D3 compared to when the first light-emitting unit 10A and the second light-emitting unit 10B are positioned at the same height. Similarly, since the first light-emitting unit 10A is positioned offset from the second light-emitting unit 10B in the lateral direction D2, the illumination range of the light from the first and second light-emitting units 10A and 10B is expanded in the lateral direction D2 compared to the case where the first light-emitting unit 10A and the second light-emitting unit 10B are positioned to overlap in the vertical direction D3.

[0043] Furthermore, by alternately flashing the first light-emitting unit 10A and the second light-emitting unit 10B, power consumption can be reduced compared to when the first light-emitting unit 10A and the second light-emitting unit 10B are flashed simultaneously.

[0044] In this way, the indicator light 1 flashes yellow in the first mode, alerting the driver of the vehicle. When the user presses the power button B2 again while the indicator light 1 is flashing yellow in the first mode, the control means stops the flashing of the first and second light sources L1 and L2. On the other hand, when the user long-presses the power button B2 while the indicator light 1 is flashing yellow in the first mode, the indicator light 1 is set to the second mode, the control means stops the flashing of the first and second light sources L1 and L2, and causes the third light source L3 and the fourth light source L4 to flash alternately.

[0045] At this time, the red light emitted from the pair of LEDs 32e and 32f constituting the third light source L3 is reflected forward D1 by the corresponding reflective surfaces 21e and 21f, becoming parallel light, which is then transmitted through the lens sections 51E and 51F and diffused. The light transmitted through lens section 51E is diffused in the horizontal direction D2 (sideways when viewed from the front), and the light transmitted through lens section 51F is diffused in the vertical direction D3 (up and down when viewed from the front). As a result, the light emitted from the third light-emitting section 10C is diffused in a cross shape as a whole. Similarly, the light emitted from the fourth light-emitting section 10D is also diffused in a cross shape as a whole.

[0046] Furthermore, since the third light-emitting unit 10C and the fourth light-emitting unit 10D are positioned diagonally opposite each other (i.e., offset in the vertical direction D3 and the width direction D2), the illumination range in the vertical and horizontal directions can be expanded compared to when light is emitted from either one of them. In addition, by flashing the third light-emitting unit 10C and the fourth light-emitting unit 10D alternately, power consumption can be reduced compared to when the third light-emitting unit 10C and the fourth light-emitting unit 10D are flashed simultaneously.

[0047] Furthermore, by having indicator light 1 flash red in this second mode, a stronger warning can be given to the vehicle driver, etc. (for example, to indicate the occurrence of an imminent danger). The reason why the operation to set indicator light 1 to the second mode is to long-press the power button B2 while indicator light 1 is flashing yellow in the first mode is to prevent indicator light 1 from being unintentionally set to the second mode.

[0048] Furthermore, when indicator light 1 is flashing red in the second mode, even if the user presses the power button B2, indicator light 1 will remain in the second mode and continue flashing red. This is to prevent accidental stopping of the red flashing in the second mode. On the other hand, when the power button B1 is pressed while indicator light 1 is flashing red in the second mode, the control means stops the flashing of the third and fourth light sources L3 and L4.

[0049] As described above, the indicator light 1 of this embodiment is configured such that the light emitted from the LED 32 is reflected forward D1 by the reflective surface 21 to become parallel light, which is then transmitted through the lens portion 51 and diffused in the horizontal direction D2 and vertical direction D3. Compared to the one disclosed in Patent Document 1, which is configured by arranging a large number of forward-facing LEDs in a matrix, the light irradiation efficiency can be improved. As a result, the number of LEDs 32 used can be reduced, and the indicator light 1 can be made smaller, lighter, and more energy-efficient without sacrificing visibility (for example, illuminance at a position 800m in front of the indicator light 1). Furthermore, the indicator light 1 can be made smaller by arranging the control board 4 and the storage battery B in the housing space S1 provided between the pair of LED boards 3A and 3B. And by making the indicator light 1 smaller and lighter in this way, it can be easily carried to, for example, a site in the middle of a station.

[0050] In this case, indicator lights and other equipment may be left behind when they are collected after the construction work is completed. However, since a GPS tag can be attached to the indicator light 1 in this embodiment as described above, by attaching a GPS tag to the indicator light 1, even if the indicator light 1 is left behind at the work site, its location can be determined using the GPS function and it can be quickly retrieved.

[0051] Furthermore, the indicator light 1 according to this embodiment is equipped with a rubber lens cover 6 and a housing cover 7, which prevents damage to the outer lens 5 and housing 2 from external impacts. In addition, the thickness of the lens cover 6 gradually increases towards the center of the lateral direction D2, and its front surface 61 has a protruding arc shape in plan view, which effectively prevents damage to the outer lens 5 from external impacts.

[0052] Although an indicator light set according to an embodiment of the present invention has been described above with reference to the attached drawings, the present invention is not limited to such embodiments, and various modifications and alterations are possible without departing from the scope of the present invention.

[0053] For example, in the above embodiment, lens sections 51A and 51B are paired, lens sections 51C and 51D are paired, lens sections 51E and 51F are paired, and lens sections 51G and 51H are paired. By setting the lens direction of the cylindrical lens 52 of one of the paired lens sections 51 to the vertical direction D3, and the lens direction of the cylindrical lens 52 of the other lens section 51 to the horizontal direction D2, light is emitted in a cross shape from the paired lens sections 51, 51 as a whole. Therefore, in the example shown in Figure 6, the lens direction of cylindrical lenses 52a, 52c, 52e, and 52g is set to the vertical direction D3, and the lens direction of cylindrical lenses 52b, 52d, 52f, and 52h is set to the horizontal direction D2. However, the present invention is not limited to such combinations, and for example, the lens direction of cylindrical lenses 52a and 52h may be set to the vertical direction D3, and the lens direction of cylindrical lenses 52b and 52g may be set to the horizontal direction D2.

[0054] As described above, the indicator light 1 is configured to be used in an orientation where the vertical direction D3 is up and down (vertical direction) and the horizontal direction D2 is horizontal. However, it can also be configured to be used in an orientation where the vertical direction D3 is horizontal and the horizontal direction D2 is up and down. In this case, a pair of magnets 8 can be provided on the side of the housing 2A or 2B instead of the lower part 2D of the housing, and screw holes 7b can be provided near the magnets 8.
