Abstract

In a rotating warning light (FR(1)), a plurality of irradiation regions (Aa to Af) that are continuous on the entire circumference in a circumferential direction (CC) are irradiated with light from a plurality of irradiation parts (Sa to Sf) corresponding thereto, respectively. Light emission control for turning on and off light sources (Ka to Kf) of the irradiation parts (Sa to Sf) such that irradiated light looks rotated in a simulated manner in a simulated rotation direction (GK) is executed. The irradiation regions are divided into a first group (G1) including first irradiation regions (Af, Aa, Ab) and a second group (G2) including second irradiation regions (Ac, Ad, Ae). The peak value of light emission intensity when first light sources (Kf, Ka, Kb) corresponding to the first group (G1) are turned on is lower than the peak value of light emission intensity when second light sources (Kc, Kd, Ke) corresponding to the second group (G2) are turned on.

Description

Technical Field

[0001] The present invention relates to , a moving body including a passenger area where passengers board and the rotating warning light is provided. The rotating warning light a moving object.

Background Art

[0002] In the pseudo-rotating lamp disclosed in Patent Document 1, a plurality of light-emitting groups are arranged on the outer peripheral surface of a cylindrical support body at predetermined intervals in the circumferential direction. Each light-emitting group is composed of a plurality of light-emitting bodies arranged substantially parallel to the axis of the support body. The control device performs control to turn on and off each light-emitting body for each light-emitting group sequentially for the next adjacent light-emitting group. Thereby, like a conventional rotating lamp, the viewer is made to have an illusion as if a reflector rotates around the light-emitting body and reflects the light of the light-emitting body.

[0003] Also, the number of light-emitting bodies located on the back side of the support body is made smaller than the number of light-emitting bodies located on the front side of the support body (that is, the viewer side). As a result, when the light-emitting body located on the back side of the support body is lit, it appears darker than when the light-emitting body located on the front side of the support body is lit. For this reason, like a conventional rotating lamp, the viewer is made to have an illusion as if a reflector reflects the light of the light-emitting body to the back side, enhancing the pseudo nature of the pseudo-rotating lamp.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when viewed from the viewer, the luminous intensity of the light-emitting body changes greatly from a high luminous intensity at the time of lighting to zero luminous intensity at the time of extinguishing. For this reason, there is a possibility that the viewer may feel uncomfortable.

[0006] Therefore, in one embodiment of the present invention, it is possible to suppress discomfortmoves Provide a moving object.

Means for Solving the Problem

[0007] One embodiment of the present invention includes includes. a plurality of light sources arranged in a circumferential direction around a central axis and emitting light in a direction away from the central axis, and a plurality of irradiation units that respectively irradiate corresponding irradiation regions among a plurality of irradiation regions arranged continuously over the entire circumference in the circumferential direction with light from the corresponding light sources, and a control unit that executes light emission control for turning on and off the plurality of light sources so that the light irradiated from the plurality of irradiation units appears to rotate pseudo-rotationally along the circumferential direction including. The plurality of irradiation regions are divided into a plurality of groups including a first group including a plurality of first irradiation regions that are continuous with each other in the circumferential direction and a second group including a plurality of second irradiation regions that are continuous with each other in the circumferential direction and are different from the first irradiation regions moving. The plurality of irradiation units include a plurality of first irradiation units that respectively irradiate corresponding first irradiation regions and a plurality of second irradiation units that respectively irradiate corresponding second irradiation regions moving. The control unit controls the light emission of the plurality of light sources so that a first peak value P1, which is a peak value of the light emission intensity when a first light source, which is a light source of the first irradiation unit, is turned on, is lower than a second peak value P2, which is a peak value of the light emission intensity when a second light source, which is a light source of the second irradiation unit, is turned on moving. The passenger area is arranged within the irradiation area of the first group of the rotating warning light. The control unit includes a plurality of light emission control modes including a first light emission control mode in which the first peak value is made lower than the second peak value, and a second light emission control mode in which the first peak value is made equal to the second peak value, and a light source control unit that controls the light emission of the plurality of light sources according to the selected light emission control mode, and a signal processing unit that outputs a mode selection signal for selecting the light emission control mode to be executed to the light source control unit in response to the input of a mode setting signal. The moving body includes a mode setting signal generator that inputs the mode setting signal to the signal processing unit.

[0008] According to this configuration, the difference in the light emission intensity between when the first light source is turned on and when it is turned off is suppressed. Therefore, when the rotating warning light is viewed from within the irradiation region of the first group, the sense of incongruity can be further suppressed.

[0011] Also the passenger area is arranged within the irradiation region of the first group of the rotating warning light because the influence of the sense of incongruity on the passengers can be further suppressed.

[0013] AlsoThe signal processing unit outputs a mode selection signal to the light source control unit in response to the input of the mode setting signal by the mode setting signal generator. The light source control unit controls the light emission of a plurality of light sources according to the selected light emission control mode.

[0014] In one embodiment, the mode setting signal generator generates a signal related to the traveling state of the moving body as the mode setting signal. According to this configuration, a mode setting signal is generated using a signal related to the traveling state of the moving body.

[0015] In one embodiment, when a signal indicating that the moving body is in motion is input as a signal related to the traveling state of the moving body to the signal processing unit, the signal processing unit outputs, as the mode selection signal, a signal for selecting the first light emission control mode to the light source control unit. According to this configuration, during the traveling of the moving body, the influence of the rotating warning light on the discomfort of the occupant is automatically more suppressed.

[0016] In one embodiment, when a signal indicating that the moving body is stopped is input as a signal related to the traveling state of the moving body to the signal processing unit, the signal processing unit outputs, as the mode selection signal, a signal for selecting the second light emission control mode to the light source control unit. According to this configuration, during the stop of the moving body, the warning property can be automatically enhanced.

[0017] In one embodiment, at least a pair of rotating warning lights are included, and the plurality of rotating warning lights are arranged on the left and right with respect to the center line of the moving body extending in the front-rear direction through the central portion in the left-right direction of the moving body in plan view, and are light emission controlled so as to appear to rotate pseudo-rotationally in opposite directions to each other. According to this configuration, the irradiation light by the left and right rotating warning lights is not misrecognized as indicating a left turn or a right turn direction.

Advantages of the Invention

[0019] This invention can provide a rotating warning light and a moving body that can further suppress discomfort.

[0021] Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

[0022] FIG. 1 is a schematic side view of a moving body to which a rotating warning lamp according to an embodiment of the present invention is applied. FIG. 2 is a schematic plan view of the moving body. An example of the moving body in this embodiment is a police motorcycle 90. A police motorcycle is a motorcycle equipped with equipment necessary for traffic control work and the like, and is a two-wheeled vehicle mainly used by the police.

[0023] As shown in FIGS. 1 and 2, the police motorcycle 90 as an example of the moving body includes a vehicle body frame 91, a plurality (three in this embodiment) of rotating warning lamps FR, FL, BR, an ECU (Electronic Control Unit) 92 as a movement control unit, a passenger seat 93, and a fuel tank 94. Usually, a passenger sits on the passenger seat 93 and rides on the police motorcycle 90. Also, when cornering in a lean-in, the passenger may lean the head inward of the corner and protrude it with the buttocks shifted by half from the passenger seat 93.

[0024] The passenger area JA is a three-dimensional area that includes the space occupied by the passenger when boarding. The passenger area JA at least includes the area above the seating area ZA of the passenger seat 93. The passenger area JA preferably includes the moving area of the passenger's head due to changes in the driving posture of the passenger. The passenger area JA includes the area arranged above or on the side of the fuel tank 94.

[0025] The vehicle body frame 91 includes a front frame 95, a rear frame 96, a pair of side protector pipes 97, a pair of guide pipes 98, and a support pole 99. The pair of side protector pipes 97 are a pair of U-shaped pipes extending in a wing shape from the front frame 95 to the left and right sides to protect the engine. The pair of guide pipes 98 are a pair of pipes extending from the rear frame 96 to the left and right sides to support and protect the left and right luggage cases with respect to the rear frame 96. The support pole 99 extends upward from the right rear part of the rear frame 96 or extends upward from the right guide pipe 98.

[0026] The three rotating warning lights FL, FR, BR include a pair of left and right rotating warning lights FL, FR arranged on the left and right of the front part of the vehicle body, and a rotating warning light BR arranged at the right rear part of the vehicle body. The pair of left and right rotating warning lights FL, FR at the front are placed and fixed on the upper surface of the mounting table 100 fixed to the pair of side protector pipes 97. The rotating warning light BR at the right rear part is placed and fixed on the upper surface of the mounting table 100 fixed to the upper end of the support pole 99. A common rotating warning light 1 is used for the three rotating warning lights FL, FR, BR.

[0027] FIG. 3 is a schematic perspective view of the rotating warning light 1. FIG. 4 is a schematic cross-sectional view of the rotating warning light 1. As shown in FIGS. 3 and 4, the rotating warning light 1 includes a globe GM composed of an outer globe 2 and an inner globe 3, three LED substrates 4, a base member BM composed of a holder 5 and a lower case 6, and a power supply substrate (not shown). The globe GM and the base member BM are combined to form a hollow housing 7. The outer globe 2 is formed of, for example, a red translucent member. The outer globe 2 is formed, for example, in a streamline shape in plan view. The inner globe 3 is formed in a substantially cylindrical shape and has a central axis C1 extending in the vertical direction.

[0028] The space inside the housing 7 is partitioned vertically by the holder 5. Inside the inner globe 3 of the housing 7, three LED substrates 4 are accommodated in the space above the holder 5. Inside the housing 7, a power supply substrate is accommodated in the space below the holder 5.

[0029] FIG. 5 is a perspective view of the arrangement state of the three LED substrates 4. As shown in FIGS. 4 and 5, an LED (light-emitting diode) 8 as a light source Ka~Kf is supported on each of the three LED substrates 4 accommodated in the inner globe 3. The radiation light from the LED 8 of the three LED substrates 4 is irradiated radially in a direction away from the central axis C1 around the central axis C1.

[0030] As shown in FIG. 4, when viewed parallel to the central axis C1, the three LED substrates 4 form an equilateral triangle surrounding the central axis C1. The three LED substrates 4 are arranged at an equal distance from the central axis C1. Each LED substrate 4 includes an outer surface 4a and an inner surface 4b. When viewed parallel to the central axis C1, the normal to the outer surface 4a of the LED substrate 4 passing through the central axis C1 is the reference normal BN. On the outer surface 4a of the LED substrate 4, at least one LED 8 (constituting each light source Ka~Kf) is arranged at a pair of symmetrical arrangement positions sandwiching the reference normal BN.

[0031] Each of the light sources Ka to Kf may be constituted by a single LED 8, or may be constituted by a plurality of LEDs 8 as shown in FIG. 5. In this embodiment, the plurality of LEDs 8 constituting each of the light sources Ka to Kf are arranged parallel to the central axis C1. The LED 8 has an optical axis 8a orthogonal to the outer surface 4a of the LED substrate 4.

[0032] As shown in FIG. 4, the rotating warning lamp 1 includes a plurality of, for example, six irradiation portions Sa, Sb, Sc, Sd, Se, Sf. The plurality of irradiation portions Sa, Sb, Sc, Sd, Se, Sf are arranged in this order in the circumferential direction CC around the central axis C1, for example, in the clockwise direction.

[0033] The plurality of irradiation portions Sa, Sb, Sc, Sd, Se, Sf include a plurality of light sources Ka, Kb, Kc, Kd, Ke, Kf that emit light in a direction away from the central axis C1. Specifically, each of the irradiation portions Sa to Sf includes a corresponding light source Ka to Kf, a corresponding cylindrical lens 30, a corresponding diffusing lens 31, and a corresponding condenser lens 32. The diffusing lens 31 is formed on the inner circumferential surface 3b of the inner globe 3. The condenser lens 32 is formed on the outer circumferential surface 3a of the inner globe 3.

[0034] The rotating warning lamp 1 includes a plurality of irradiation regions Aa, Ab, Ac, Ad, Ae, Af corresponding to the plurality of irradiation portions Sa, Sb, Sc, Sd, Se, Sf, respectively. The plurality of irradiation regions Aa, Ab, Ac, Ad, Ae, Af are arranged so as to be continuous over the entire circumference of the circumferential direction CC. The plurality of irradiation regions Aa, Ab, Ac, Ad, Ae, Af and the corresponding plurality of irradiation portions Sa, Sb, Sc, Sd, Se, Sf have the same arrangement with respect to the circumferential direction CC.

[0035] When viewed parallel to the central axis C1, in a plurality of irradiation regions Aa to Af arranged in clockwise direction CW with the central axis C1 as the center, with the front X1 being the 12 o'clock direction and the rear X2 being the 6 o'clock direction, the irradiation region Aa is the region from 6 o'clock to 8 o'clock. The irradiation region Ab is the region from 8 o'clock to 10 o'clock. The irradiation region Ac is the region from 10 o'clock to 12 o'clock. The irradiation region Ad is the region from 12 o'clock to 2 o'clock. The irradiation region Ae is the region from 2 o'clock to 4 o'clock. The irradiation region Af is the region from 4 o'clock to 6 o'clock.

[0036] Each irradiation unit Sa to Sf irradiates the light from its corresponding light source Ka to Kf toward the corresponding irradiation regions Aa to Af. Specifically, the irradiation unit Sa irradiates the light from the light source Ka toward the irradiation region Aa. The irradiation unit Sb irradiates the light from the light source Kb toward the irradiation region Ab. The irradiation unit Sc irradiates the light from the light source Kc toward the irradiation region Ac. The irradiation unit Sd irradiates the light from the light source Kd toward the irradiation region Ad. The irradiation unit Se irradiates the light from the light source Ke toward the irradiation region Ae. The irradiation unit Sf irradiates the light from the light source Kf toward the irradiation region Af.

[0037] In the rotating warning lamp 1, a plurality of irradiation regions Aa to Af can be selectively divided into a plurality of groups. For example, as shown in FIGS. 9 and 11(1) to (4), the plurality of irradiation regions Aa to Af can be selectively divided into the irradiation regions of the first group G1 and the irradiation regions of the second group G2. The first group G1 includes a plurality of first irradiation regions that are continuous with each other in the circumferential direction CC. The second group G2 includes a plurality of second irradiation regions that are continuous with each other in the circumferential direction CC. The first irradiation region and the second irradiation region are different from each other. In the irradiation regions of the first group G1, the light emission intensity at the time of lighting of the corresponding light source is suppressed to be low with respect to the irradiation regions of the second group G2. That is, the irradiation regions of the first group G1 correspond to a dimming region in which the light emission intensity at the time of lighting of the corresponding light source is suppressed to be low with respect to the irradiation regions of the second group G2.

[0038] The rotation warning light 1 includes a control unit 10 (see FIG. 7) including a light source control unit 12 that performs light emission control to turn on and off a plurality of light sources Ka to Kf (LED8) so that the light emitted from the plurality of irradiation units Sa to Sf appears to rotate pseudo-rotationally in the pseudo-rotation direction along the circumferential direction CC.

[0039] Further, the light source control unit 12 can execute light emission control according to a light emission control mode selected from a plurality of light emission control modes. Specifically, the first to fourth light emission control modes (see FIG. 10) can be selected.

[0040] In the first light emission control mode, as shown in FIG. 12, a first peak value P1, which is the peak value of the light emission intensity when, for example, light sources Kf, Ka, and Kb, which are the light sources of the irradiation units corresponding to the irradiation region of the first group G1 (first light sources), are turned on, is made smaller than a second peak value P2, which is the peak value of the light emission intensity of, for example, light sources Kc, Kd, and Ke, which are the light sources of the irradiation units corresponding to the irradiation region of the second group G2 (second light sources). Thereby, the irradiation region of the first group G1 is irradiated with less light than the irradiation region of the second group G2.

[0041] In the first light emission control mode, the first peak value P1 may be set to less than 10% of the second peak value P2, may be set to 10% or more and less than 20%, or may be set to 20% or more and less than 30%.

[0042] Further, in the first light emission control mode, for example, when the group division corresponding to FIG. 11(1) is made, with the 2 o'clock direction as direction Y1, the 4 o'clock direction as direction Y2, the 8 o'clock direction as direction Y3, and the 10 o'clock direction as direction Y4, the waveforms of the light emission intensities in the respective directions Y1 to Y4 are as shown in FIG. 13. That is, the peak value of the light emission intensity is the highest in direction Y1 and the lowest in direction Y3. Also, in directions Y2 and Y4, which correspond to the direction of the boundary between the irradiation region of the first group G1 and the irradiation region of the second group G2, the peak value of the light emission intensity is, for example, 50% or less with respect to direction Y1.

[0043] The lengths of the white arrows representing the directions Y1 to Y4 are set to schematically represent the magnitudes of the peak values of the emission intensity. The same applies to the white arrows representing the directions Y1 to Y4 when the group classification in FIGS. 11(2) to (4) is performed.

[0044] Also, in the first emission control mode, as shown in FIG. 12, the width W1 of the emission time from the lighting start timing to the lighting end timing of, for example, the light sources Kf, Ka, Kb (first light sources) corresponding to the irradiation region of the first group G1 is equal to the width W2 of the emission time from the lighting start timing to the lighting end timing of, for example, the light sources Kc, Kd, Ke (second light sources) corresponding to the irradiation region of the second group G2. Further, the waveform of the emission intensity in the emission time of the light sources Kf, Ka, Kb (first light sources) is formed by a waveform reduced at a reduction ratio corresponding to P1 / P2 with respect to the waveform of the emission intensity in the emission time of the light sources Kc, Kd, Ke (second light sources).

[0045] Also, in the second emission control mode, for example, as shown in FIG. 14, the first peak value P1 is made equal to the second peak value P2. Thereby, bright irradiation is performed for each irradiation region.

[0046] Also, in the third emission control mode, the first peak value is made equal to the second peak value, similar to the second emission control mode. However, the first and second peak values in the third emission control mode are made smaller than the first and second peak values in the second emission control mode.

[0047] Also, in the fourth emission control mode, the light sources corresponding to the irradiation region of the first group G1 are constantly turned off, and only the light sources of the irradiation unit corresponding to the irradiation region of the second group G2 are emission-controlled.

[0048] FIG. 7 is a block diagram showing the electrical configuration of the rotating warning lamp 1. As shown in FIG. 7, the control unit 10 includes a power supply control unit 11, a light source control unit 12, and a signal processing unit 13. The power supply control unit 11 is electrically connected to the power supply 40. The power supply control unit 11 supplies the power from the power supply to each LED 8 etc. via the light source control unit 12.

[0049] The light source control unit 12 controls the light emission of each LED 8 using PWM (Pulse Width Modulation) control according to the selected pseudo-rotation direction, the selected group classification, the selected number of rotations per unit time, and the selected light emission control mode. The light source control unit 12 changes the applied voltage to a switching element (not shown) as desired so that a desired light emission intensity waveform as shown in, for example, FIGS. 12 and 14 can be obtained in the light emission intensity of the light source by controlling the PWM signal duty ratio.

[0050] A first switch 21 and a second switch 22 are connected to the signal processing unit 13. The first switch 21 is a setting switch that can select a plurality of positions (states), for example, 4 positions (4 states) by manual operation as shown in FIG. 8A which is a schematic diagram. The first switch 21 may be, for example, a 2-bit dip switch. The second switch 22 is a setting switch that can select a plurality of positions (states) by manual operation. The second switch 22 may be, for example, a 9-position (9-state) rotary switch as shown in FIG. 8B which is a schematic diagram.

[0051] Further, the signal processing unit 13 is connected to a mode setting signal generator 92a provided in the ECU 92 which is a movement control unit. The signal processing unit 13 is connected to the mode setting signal generator 92a via a pair of signal lines L1, L2. Each of the signal lines L1, L2 transmits ON and OFF signals and gives a total 2-bit signal to the signal processing unit 13.

[0052] The light source control unit 12 has four patterns regarding the pseudo-rotation direction GK and the group classification of the first group G1 and the second group G2 as a first table (see FIG. 9).

[0053] The first switch 21 outputs a first setting signal S1 for setting a corresponding pseudo-rotation direction and group classification to the signal processing unit 13 according to the position set from among the first to fourth positions. The signal processing unit 13 outputs a first selection signal SS1 for selecting a pseudo-rotation direction and group classification to the light source control unit 12 according to the first setting signal S1 input from the first switch 21.

[0054] Also, the light source control unit 12 stores in an internal memory a second table (see FIG. 10. FIG. 10 shows only the patterns corresponding to the fifth to ninth positions of the second switch 22) in which a number of patterns are set regarding the number of rotations per unit time and the light emission control mode. As shown in FIG. 10, the number of rotations per unit time corresponding to the fifth to ninth positions is "60 rotations / minute", "120 rotations / minute", "180 rotations / minute", "250 rotations / minute", "312 rotations / minute". The number of rotations per unit time may be set in any manner, for example, arbitrarily set between 60 rotations / minute and 312 rotations / minute.

[0055] The second switch 22 outputs a second setting signal S2 (mode setting signal) corresponding to the set position to the signal processing unit 13. In the signal processing unit 13, a second selection signal SS2 (mode selection signal) is output to the light source control unit 12 according to the combination of the second setting signal S2 (mode setting signal) input from the second switch 22 and the signal inputs of ON and OFF of the signal lines L1 and L2.

[0056] In the light source control unit 12, the pseudo-rotation direction GK determined based on the first table (see FIG. 9) and the first selection signal SS1 for selecting the pseudo-rotation direction and group classification input from the signal processing unit 13, and the group classification of the first group G1 and the second group G2, and the number of rotations and the light emission control mode determined based on the second table (see FIG. 10) and the second selection signal SS2 (mode selection signal) input from the signal processing unit 13, each LED 8 is controlled for light emission.

[0057] In the three rotating warning lights FL, FR, and BR, the initial settings regarding the irradiation areas of the first group G1 and the second group G2 are made different from each other. Specifically, as shown in FIG. 6, the irradiation areas of the rotating warning lights FL, FR, and BR are initially set such that the passenger area JA is arranged within the irradiation area of the first group G1, which is the dimming area of each rotating warning light FL, FR, and BR.

[0058] That is, as shown in FIG. 6, in the right front rotating warning light FR, the first switch 21 is set to the first position (refer to the first table in FIG. 9), and the rotating warning light 1 with the group classification initially set as shown in FIG. 11(1) is used. As shown in FIG. 6, in the right front rotating warning light FR, the pseudo-rotation direction GK is the clockwise direction CW.

[0059] In the right front rotating warning light FR, the irradiation areas Af, the irradiation area Aa, and the irradiation area Ab that are continuous in the circumferential direction CC with each other are the irradiation areas of the first group G1. The passenger area JA is arranged within the irradiation area of the first group G1, that is, within at least one of the irradiation areas Af, the irradiation area Aa, and the irradiation area Ab. Also, in the right front rotating warning light FR, the irradiation areas Ac, the irradiation area Ad, and the irradiation area Ae that are continuous in the circumferential direction CC with each other are the irradiation areas of the second group G2.

[0060] In the left front rotating warning light FL, the first switch 21 is set to the second position (refer to the first table in FIG. 9), and the rotating warning light 1 with the group classification initially set as shown in FIG. 11(2) is used. As shown in FIG. 6, in the left front rotating warning light FL, the pseudo-rotation direction GK is the counterclockwise direction CCW. In the left front rotating warning light FL, the pseudo-rotation direction GK is in the opposite direction to the pseudo-rotation direction GK of the right front rotating warning light FR.

[0061] In the left front rotating warning lamp FL, as shown in FIG. 15, a first peak value P1, which is the peak value of the emission intensity when, for example, light sources Ke, Kf, and Ka, which are light sources (first light sources) of the irradiation unit corresponding to the irradiation area of the first group G1, is made smaller than a second peak value P2, which is the peak value of the emission intensity of light sources (second light sources), for example, Kb, Kc, and Kd, of the irradiation unit corresponding to the irradiation area of the second group G2. Thereby, irradiation with reduced light is performed on the irradiation area of the first group G1 compared to the irradiation on the irradiation area of the second group G2.

[0062] Also, in the left front rotating warning lamp FL, the time change of the emission intensity (intensity of the emitted light) observed in each direction is as shown in FIG. 16. The peak value of the emission intensity is the highest in the direction Y4 and the lowest in the direction Y2. Also, in the directions Y1 and Y3, which correspond to the direction of the boundary between the irradiation area of the first group G1 and the irradiation area of the second group G2, the peak value of the emission intensity is, for example, 50% or less with respect to the direction Y4.

[0063] In the left front rotating warning lamp FL, as shown in FIG. 6, the irradiation areas Ae, Af, and Aa that are continuous in the circumferential direction CC with each other are the irradiation areas of the first group G1. The passenger area JA is arranged within the irradiation area of the first group G1, that is, within at least one of the irradiation areas Ae, Af, and Aa. Also, in the left front rotating warning lamp FL, the irradiation areas Ab, Ac, and Ad that are continuous in the circumferential direction CC with each other are the irradiation areas of the second group G2.

[0064] In the right rear rotating warning lamp BR, the first switch 21 is set to the third position (refer to the first table in FIG. 9), and the rotating warning lamp 1 with the group classification initially set as shown in FIG. 11(3) is used. As shown in FIG. 6, in the right rear rotating warning lamp BR, the pseudo-rotation direction GK is the clockwise direction CW.

[0065] In the right rear rotation warning light BR, irradiation regions Ab, irradiation region Ac, and irradiation region Ad that are continuous with each other in the circumferential direction CC are irradiation regions of the first group G1. Inside the irradiation regions of the first group G1, that is, inside at least one of the irradiation regions Ab, irradiation region Ac, and irradiation region Ad, the passenger area JA is arranged. Also, in the right rear rotation warning light BR, irradiation regions Ae, irradiation region Af, and irradiation region Aa that are continuous with each other in the circumferential direction CC are irradiation regions of the second group G2.

[0066] Also, in the three rotation warning lights FL, FR, and BR, the number of rotations per unit time is made equal to each other and is in the first light emission control mode. For example, when the second switch is set to the fifth position (refer to the second table in FIG. 10), and the signal via the signal line L1 is an OFF signal and the signal via the signal line L2 is an ON signal, the number of rotations is set to "60 rotations / minute" and is in the "first light emission control mode".

[0067] Also, the mode setting signal generator 92a of the ECU 92 (travel control unit) generates a signal regarding the running state of the white vehicle 90. Specifically, the mode setting signal generator 92a determines whether the white vehicle 90 is running or stopped, for example, based on the speed signal of the white vehicle 90.

[0068] When it is determined that the vehicle is running, the mode setting signal generator 92a outputs an OFF signal via the signal line L1 and an ON signal via the signal line L2 to the signal processing unit 13 as signals indicating that the vehicle is running. In response to the input of a signal indicating that the vehicle is running, the signal processing unit 13 outputs a signal for selecting the first light emission control mode to the light source control unit 12.

[0069] Also, when it is determined that the vehicle is stopped, the mode setting signal generator 92a outputs an OFF signal via the signal line L1 and an OFF signal via the signal line L2 to the signal processing unit 13 as signals indicating that the vehicle is stopped. In response to the input of a signal indicating that the vehicle is stopped, the signal processing unit 13 outputs a signal for selecting the second light emission control mode to the light source control unit 12. That is, the light emission control mode is automatically switched according to the running and stopping of the white bus 90.

[0070] According to this embodiment, light emitted from a plurality of irradiation units Sa to Sf corresponding to a plurality of irradiation regions Aa to Af continuous over the entire circumference of the circumferential direction CC, such as the rotation warning lamp FR at the right front part in FIG. 6, is made to appear to rotate pseudo-rotationally in the pseudo-rotation direction GK, and light emission control for turning on and off the light sources Ka to Kf of the plurality of irradiation units Sa to Sf is executed. The plurality of irradiation regions Aa to Af are divided into a first group G1 including a plurality of first irradiation regions Af, Aa, Ab that are continuous with each other in the circumferential direction CC, and a second group G2 including a plurality of second irradiation regions Ac, Ad, Ae that are continuous with each other in the circumferential direction CC and are different from the first irradiation regions Af, Aa, Ab.

[0071] As shown in FIG. 12, the plurality of light sources Ka to Kf are light emission-controlled such that a first peak value P1, which is the peak value of the light emission intensity when the first light sources (light sources Kf, Ka, Kb), which are the light sources of the first irradiation units (irradiation units Sf, Sa, Sb) corresponding to the first irradiation regions Af, Aa, Ab of the first group G1, are turned on, is lower than a second peak value P2, which is the peak value of the light emission intensity when the second light sources (light sources Kc, Kd, Ke), which are the light sources of the second irradiation units (irradiation units Sc, Sd, Se) corresponding to the second irradiation regions Ac, Ad, Ae of the second group G2, are turned on. For this reason, when the rotation warning lamp FR is viewed from within the irradiation region of the first group G1, the difference in the light emission intensity between when the first light sources (light sources Kf, Ka, Kb) are turned on and off is suppressed. Thereby, a sense of incongruity can be suppressed.

[0072] Also, as shown in FIG. 12, the width W1 of the light emission time of the first light sources (light sources Kf, Ka, Kb) and the width W2 of the light emission time of the second light sources (light sources Kc, Kd, Ke) are made equal to each other. The waveform of the light emission intensity in the light emission time of the first light sources (light sources Kf, Ka, Kb) is formed by a waveform reduced at a reduction ratio corresponding to P1 / P2 with respect to the waveform of the light emission intensity in the light emission time of the second light sources (light sources Kc, Kd, Ke). Therefore, it becomes easier to see as if light is continuously flowing in the pseudo-rotation direction.

[0073] Also, for the plurality of light sources Ka to Kf, light emission control in a selected light emission control mode is possible. That is, by the light emission control in the first light emission control mode, the sense of incongruity when viewing the rotation warning lights FR, FL, BR from within the irradiation area of the first group G1 can be further suppressed. Also, as shown in FIG. 14, by the light emission control in the second light emission control mode in which the peak values of the light emission intensities of the first light sources (light sources Kf, Ka, Kb) and the second light sources (light sources Kc, Kd, Ke) are made equal to each other, the warning property can be enhanced.

[0074] Also, as shown in FIG. 6, the occupant area JA occupied by the occupant is arranged within the irradiation area of the first group G1 of each of the rotation warning lights FR, FL, BR. Therefore, the influence of the sense of incongruity on the occupant can be further suppressed.

[0075] Also, the signal processing unit 13 outputs a mode selection signal SS2 to the light source control unit 12 in response to the input of a mode setting signal by the mode setting signal generator 92a of the ECU92 (movement control unit). The light source control unit 12 can perform light emission control of the plurality of light sources Ka to Kf according to the selected light emission control mode.

[0076] Also, the mode setting signal generator 92a generates a signal regarding the running state of the white bus 90 as a mode setting signal. Therefore, a mode setting signal can be generated using the signal regarding the running state of the white bus 90.

[0077] Further, in response to the input of a signal indicating that the white vehicle 90 is in a traveling state as a signal related to the traveling state of the white vehicle 90, the signal processing unit 13 outputs, as a mode selection signal, a signal for selecting the first light emission control mode to the light source control unit 12. For this reason, while the white vehicle 90 is traveling, it is possible to automatically further suppress the rotating warning lights FR, FL, and BR from giving a sense of discomfort to the passengers.

[0078] Also, in response to the input of a signal indicating that the white vehicle 90 is in a stopped state as a signal related to the traveling state of the white vehicle 90, the signal processing unit 13 outputs, as a mode selection signal, a signal for selecting the second light emission control mode to the light source control unit 12. For this reason, while the white vehicle 90 is stopped, the warning property can be automatically enhanced.

[0079] Also, with respect to the moving body center line C2 that extends in the front-rear direction through the central portion in the left-right direction of the white vehicle 90 in a plan view, the right front rotating warning light FR and the left front rotating warning light FL are arranged on the left and right. The right front rotating warning light FR and the left front rotating warning light FL are controlled to emit light so as to seemingly rotate in opposite directions to each other. For this reason, the irradiation light by the left and right rotating warning lights is not misrecognized as indicating a left turn or a right turn direction. The pseudo-rotation directions of the left and right rotating warning lights may be such that one is in the clockwise direction CW and the other is in the counterclockwise direction CCW.

[0080] FIG. 17 is a schematic plan view of a construction machine 90P as a moving body. In addition to the right front rotating warning light FR, the left front rotating warning light FL, and the right rear rotating warning light BR having the same configuration as the white vehicle 90 in FIG. 6 for the construction machine 90P, a left rear rotating warning light BL is applied. In the left rear rotating warning light BL, the first switch 21 is set to the fourth position (refer to the first table in FIG. 9), and the rotating warning light 1 with the group classification initially set as shown in FIG. 11(4) is used.

[0081] As shown in FIG. 17, the pseudo-rotation direction GK of the left-rear rotation warning light BL is counterclockwise (CCW). The pseudo-rotation direction GK of the left-rear rotation warning light BL is opposite to the pseudo-rotation direction GK of the right-rear rotation warning light BR.

[0082] In the left-rear rotation warning light BL, the irradiation regions Ac, Ad, and Ae that are continuous in the circumferential direction CC with each other are the irradiation regions of the first group G1. The passenger area JA is arranged within the irradiation regions of the first group G1, that is, within at least one of the irradiation regions Ac, Ad, and Ae. Also in the construction machine 90P, it is possible to suppress the passengers from being affected by discomfort.

[0083] FIG. 18 is a schematic plan view of a drone 90Q as a moving body. For the drone 90Q, a right-front rotation warning light FR, a left-front rotation warning light FL, a right-rear rotation warning light BR, and a left-rear rotation warning light BL having the same configuration as the construction machine 90P in FIG. 17 are applied. The drone 90Q includes a device arrangement area KHA where a device 70 (such as a camera, an optical sensor, etc.) having a light receiving portion 71 is arranged. The device arrangement area KHA is a three-dimensional area including the space occupied by the device 70. The device arrangement area KHA is arranged within the irradiation regions of the first group G1 of each rotation warning light FR, FL, BR, BL. Therefore, in the drone 90Q, it is possible to suppress the rotation warning lights from affecting the device 70 having the light receiving portion 71.

[0084] The present invention is not limited to the above-described embodiment. For example, although not shown, a manually operable mode setting switch may be provided as a mode setting signal generator connectable to the signal lines L1, L2. Also, the LED substrate may be arranged in a polygon having four or more sides. Further, the LEDs may be arranged on a cylindrical surface.

[0085] Also, although not shown, in the white van, when the rear rotating warning lamp is arranged singly at the center in the left - right direction, the plurality of irradiation regions may be divided into a first group of irradiation regions centered on the 12 o'clock direction and a second group of irradiation regions centered on the 6 o'clock direction.

[0086] Also, the rotating warning lamp is not limited to a moving body, and may be attached to and used on a fixed body such as mechanical equipment or the wall of a building. In addition, the present invention can be variously modified within the scope described in the claims.
