  An indicator lamp called a row lamp mounted on the roof of a vehicle such as a taxi is illuminated with a light bulb or the like inside. These mechanisms are a mechanism in which a fluorescent lamp or an LED bulb board is covered with an acrylic milk plate to emit light.

  Here, when a fluorescent lamp is used for the row lamp described above, there is a problem that flickering or blinking occurs due to deterioration of the fluorescent lamp bulb. In addition, when LED bulbs are used for the above-mentioned lamps, the deterioration of fluorescent lamp bulbs can be avoided, but the lighting of buildings and vehicles at night has almost been replaced with LEDs, and the luminance of the lamps is insufficient. There is. In other words, because the brightness of the lighting of buildings at night and the brightness of the lights of taxis, etc. are equal, even if a taxi at night runs with the lights on, it will be mixed with the lighting of surrounding buildings, From the user's point of view, there is a problem that it is difficult to distinguish. In addition, current taxi lamps have a problem that they simply shine and lack novelty to attract users.

  Therefore, the present invention has been made to solve the above-described problem, and provides a row lamp that can easily attract the user's eyes by shining with a unique color at an appropriate timing at night. For the purpose.

  The row lamp according to the present invention includes an exterior, a phosphorescent body, a light source unit, and a light source control unit. The exterior is arranged on the roof of the taxi and is made of a light transmissive material. The phosphor is incorporated in the exterior. The light source unit is provided inside the exterior and emits light in a specific wavelength region that causes the phosphorescent body to emit light. At night, the light source control unit turns on the light source unit while driving in an empty vehicle or in standby, and turns off the light source unit during driving of an actual vehicle, in conjunction with the indicator light of the taxi fare meter.

  The phosphor is a phosphor layer having a plurality of voids obtained by dispersing and fixing a plurality of phosphor particles having a specific range of particle diameters on the inner surface of the exterior. The phosphor layer has a thickness in the range of 1 mm to 5 mm. The phosphorescent body emits blue light in response to ultraviolet light, and the light source unit emits ultraviolet light.

  According to the row lamp according to the present invention, it is possible to easily attract the eyes of the user by causing the original color to shine at an appropriate timing at night.

  Below, with reference to an accompanying drawing, an embodiment of a line light concerning the present invention is described, and it serves for an understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  As shown in FIG. 1, the row lamp 1 according to the present invention includes an exterior 10, a phosphorescent body P, a light source unit 11, and a light source control unit 12. The exterior 10 is disposed on the roof 13a of the taxi 13 and is made of a light transmissive material. The phosphor P is incorporated in the exterior 10. The light source unit 11 is provided in the exterior 10 and emits light in a specific wavelength region that causes the phosphor P to emit light. At night, the light source control unit 12 interlocks with the indicator light 13b of the taxi 13 to turn on the light source unit 11 during running or standby, and to turn off the light source unit 11 during actual vehicle running. .

  Here, at night, the light source 11 can be turned on in conjunction with the indicator lamp 13a of the toll meter, and when the vehicle is running or on standby, the luminous substance P can be illuminated with a unique color. Here, the color of light emitted from the phosphor P has a feature that it is more likely to attract the user's eyes at night compared to the color of light from a fluorescent lamp or LED. Therefore, when the user looks at the row lamp 1 that is running or waiting at night, the user can easily watch the color of the phosphor P of the row lamp 1 and can find the taxi 13 immediately. If the user wants to take a taxi 13, he can immediately find the row lamp 1 shining with the phosphor P and raise his hand to call the taxi 13.

  On the other hand, when the vehicle is traveling at night, the light source unit 11 is turned off in conjunction with the indicator lamp 13b of the charge meter. Here, when the light source unit 11 is switched from the lighted state to the lighted state, the phosphor P, which has been received until now, dimly emits a unique color due to the afterglow. In this case, since the row lamp 1 is difficult to touch the user's eyes, it is possible to prevent the user from accidentally raising his / her hand on the taxi 13 that is traveling in the actual vehicle. Further, turning off the light source unit 11 contributes to energy saving.

  In addition, although the light emission luminance, the afterglow luminance, the afterglow time, and the like vary depending on the type of the phosphor P, in the specific period, the taxi 13 has a higher frequency of running or waiting than an actual vehicle. In such a case, the light source unit 11 is frequently turned on. Then, since the phosphor P also frequently remains after receiving the light from the light source unit 11, the phosphor P shines with afterglow at an appropriate frequency during actual vehicle travel.

  As described above, according to the present invention, it is possible to easily attract the eyes of the user by making the original color shine at an appropriate timing at night.

  In the daytime (daytime), if the light source unit 11 is not turned on, the sunlight includes light in any wavelength region (infrared light, visible light, ultraviolet light, etc.). And the phosphor P normally emits light in response to the light in the specific wavelength region in the sunlight. Thereby, even in the daytime, it becomes possible to shine the row lamp 1 weakly without power.

  Next, each configuration will be described in detail. Although the material of the exterior 10 is not particularly limited, for example, a transparent resin (methacrylic resin, acrylic resin, etc.) having heat resistance and light resistance is adopted. The shape of the exterior 10 is not particularly limited. For example, as shown in FIGS. 2A and 2B, a hemisphere having a hollow inside is employed.

  Here, the phosphorescent body P is not particularly limited as long as it is a phosphorescent body P that receives light in a specific wavelength region for a certain period of time and then retains after receiving light (self-emission). For example, known visible light Or a known ultraviolet light, or a known visible light and ultraviolet light accumulator. Moreover, although there is no limitation in particular in the form of the luminous body P, For example, the coating material, the pigment, luminous body particulates, etc. which contained the luminous body P can be mentioned. Moreover, although there is no limitation in particular in the luminescent color of the luminous body P, For example, the color which produces a human's visual interest easily at night, specifically, blue, yellowish green, etc. can be mentioned.

  The method for incorporating the phosphorescent body P into the outer package 10 is not particularly limited. For example, a method of coating the inner surface or the outer surface of the outer casing 10 with a paint containing the phosphorescent body P, the phosphorescent body P (fine particles) Examples thereof include a method of kneading and molding the material, a method of including the phosphorescent body P in an adhesive tape, and affixing the tape to the inner surface or the outer surface of the exterior 10 and the like. As shown in FIGS. 2 (A) and 2 (B), the phosphor P is made to disperse and fix a plurality of phosphor particles 14 having a specific range of particle diameters on the inner surface of the exterior 10. It is good also as the luminous body layer P which is obtained by this and has the some space | gap O. By providing the phosphorescent layer P on the inner surface of the exterior 10, the phosphorescent layer P is prevented from falling off the exterior 10 due to wind pressure while the taxi 13 is traveling. The film thickness of the daylight layer P may be uniform or nonuniform at any location on the inner surface of the exterior 10. By deliberately providing a plurality of gaps O in the phosphor layer P, the joy of the lamp 1 at night is emphasized.

  In addition, you may combine the fluorescent substance P of this invention with a fluorescent whitening agent (for example, rhodamine of a fluorescent pigment | dye). The fluorescent whitening agent is not particularly limited as long as it is self-luminous while being irradiated with light, and visible light fluorescent whitening agent, ultraviolet light brightening agent, or visible light and ultraviolet light. And a fluorescent brightening agent. The form of the fluorescent brightening agent is not particularly limited, and examples thereof include paints, pigments and fluorescent brightening agent fine particles containing the fluorescent brightening agent.

  In addition, a lid portion 15 made of, for example, a heat-resistant material (ABS resin or the like) is provided on the bottom surface of the exterior 10, and a light source that causes the phosphor particles 14 to emit light on the top surface of the lid portion 15. A portion 11 is arranged, and an adsorption portion 16 that can be adsorbed to the roof 13 a of the taxi 13 is arranged on the lower surface of the lid portion 15.

  The number of the light source units 11 is appropriately designed depending on the shape and size of the exterior 10. For example, when the shape of the exterior 10 is hemispherical, the six light source units 11 are provided radially with respect to the center of the lid 15. Thereby, the light of the light source part 11 can be uniformly irradiated to the luminous layer P of the inner surface of the exterior 10. In addition, the number of the light source units 11 may be 1, 2, 3, 4, 5, etc. in addition to six. For example, as shown in FIG. 2C, the three light source parts 11 may be provided radially with respect to the center of the lid part 15. Further, the number of the light source units 11 is related to the irradiation angle (beam angle) of the light emitted from the light source unit 11. For example, when the light irradiation angle of the light source unit 11 is 120 degrees, the number is shown in FIG. As described above, it is preferable to install the six light source units 11 because the light storage layer P can be uniformly irradiated with light.

  Further, the type of the light source unit 11 is not particularly limited as long as it emits light in a wavelength region that can excite the excitation substance of the phosphor (and the fluorescent whitening agent described later). Known lamps such as incandescent bulbs, fluorescent lamps, LEDs, and black lights can be used.

  Moreover, although there is no limitation in particular in the structure of the light source part 11, as shown in FIG.2 (D), the light source part 11 has the LED part 11a which emits the light of a specific wavelength range, and has heat dissipation, A base part 11b for fixing the LED part 11a and a wiring 11c electrically connected to the LED part 11a are provided. By imparting heat dissipation to the base portion 11b, it is possible to prevent heat from being stored even when the LED portion 11a is lit while the vehicle is running for a long time or in standby. The light source unit 11 is composed of an electrostatic protection diode, and the DC forward current, the pulse forward current, the reverse voltage, the allowable power, the operating temperature range, and the storage temperature range can be applied to either a dry battery or a taxi battery. It is a range. The light source unit 11 has a DC forward voltage, a DC reverse current, a radiant flux, a dominant wavelength, and a half-value angle within a range where the phosphor P can be illuminated. As shown in FIGS. 2A and 2B, the wirings 11 c of the plurality of light source units 11 are inserted through through holes provided in advance in the base portion 11 b and the lid portion 15, for example, and the lid portion 15. And is bundled and electrically connected to the light source controller 12 provided in the vicinity of the indicator lamp 13b of the fare meter of the taxi 13. For example, the wiring 11c extends from the roof of the taxi 13 to the vicinity of the indicator lamp 13b along a door frame on which a rear seat door or a front seat door is mounted.

  Further, the number of the suction portions 16 is appropriately designed according to the shape and size of the exterior 10. For example, when the shape of the exterior 10 is hemispherical, the six suction portions 16 are radial with respect to the center of the lid portion 15. , Provided along the (circular) peripheral edge of the lid 15. Thereby, it becomes possible to fix the row lamp 1 to the roof 13a of the taxi 13 firmly. Further, by making the suction part 16 a suction cup, for example, the row lamp 1 can be easily attached to the existing taxi 13 later, and it can be easily removed when not needed. Further, the adsorbing portion 16 is not limited to a suction cup, and for example, a magnet member such as a rubber magnet or a permanent magnet, a mechanical fixing member such as a screw, or a chemical adhesive member such as an adhesive may be used.

  Here, the phosphor layer P is composed of a plurality of phosphor particles 14 having a specific range of particle diameters, as shown in FIG. The plurality of phosphor particles 14 may all have a uniform particle diameter or a non-uniform particle diameter. Moreover, the particle diameter of the phosphor particles 14 fixed to the inner surface of the exterior 10 is preferably in the range of 0.6 mm to 5.0 mm, for example. Thereby, the light of the light storage unit 11 can be effectively diffused and reflected by the light storage layer P to make the light of the light storage layer P stand out. Even if the phosphor layer P is formed by a plurality of phosphor particles 14 in which various particle sizes are mixed, for example, the phosphor is composed of a plurality of phosphor particles 14 having a particle diameter in the range of several mm to several tens of mm. The layer P may be formed.

  For example, at night, when the vehicle is running or on standby, the light source unit 11 is turned on, and the light L from the light source unit 11 is stored in each phosphor layer P of the phosphor layer P as shown in FIG. 14 is irradiated. Here, since there are a plurality of voids O in the phosphor layer P, the light L is diffused and reflected on the surface of the phosphor particles 14, and each phosphor particle 14 emits light of unique color PL1, The light will shine. Further, not all the light L is irradiated and reflected on each phosphor particle 14, but a part of the light L leaks from the gap O and the leaked light L is irradiated to the outside.

  Then, the entire lamp 1 shines by mixing the light L of the light source unit 11 and the light PL1 having a characteristic color of the phosphor layer P. Therefore, the brightness of the entire row lamp 1 becomes very strong as compared with the brightness of light of a normal fluorescent lamp or LED, and the user's eyes are easily attracted. On the other hand, when the light source unit 11 is turned off, only the afterglow PL2 of the phosphor layer P is dimly lit, which is very weak compared to the light of a normal fluorescent lamp or LED. In this way, at night, the brightness of the light of the row lamp 1 varies greatly depending on whether the vehicle is running empty (standby) or running on the actual vehicle. It can be clearly distinguished.

  Further, the film thickness of the phosphor layer P is not particularly limited, but is preferably in the range of 1 mm to 5 mm, for example. As a result, when the phosphor layer P is irradiated with the light from the light source unit 11, the light can be diffused and reflected by the phosphor particles 14 and can be appropriately transmitted. Is possible.

  Further, the light source control unit 12 is provided in the vicinity of the indicator lamp 13 a of the fare maker of the taxi 13. Here, the indicator lamp 13a of the charge maker 17 is supplied with electric power (current) from the battery 18 of the taxi 13 via the switching unit 19 of the charge maker 17 as shown in FIG. The switching unit 19 functions as a power supply switch, and in conjunction with the stop (empty or standby) or operation (actual vehicle) of the charge maker 17, supplies power to the indicator lamp 13 a (ON state) or cuts off ( Off state). For example, when the charge maker 17 stops (empty or standby), the switching unit 19 supplies power (ON state) to turn on the indicator lamp 13a. On the other hand, when the charge maker 17 operates (actual vehicle), the switching unit 19 cuts off the power (OFF state) and turns off the indicator lamp 13a.

  Here, as shown in FIG. 4A, the light source control unit 12 electrically connects the wiring 11c of the light source unit 11 to the wiring 19a between the switching unit 19 and the indicator lamp 13a. The connection unit 12 functions as the light source control unit 12. For example, when the charge maker 17 stops (empty or standby), the switching unit 19 is turned on, so that the power of the battery 18 is supplied to the indicator lamp 13a and the connection unit 12 The power of the battery 18 is also supplied to the light source unit 11. Therefore, both can be lit. On the other hand, when the charge maker 17 operates (actual vehicle), the switching unit 19 is turned off, so that the power supply of the indicator lamp 13a is cut off and the power of the light source unit 11 is connected via the connection unit 12. Supply is also cut off. Therefore, both can be turned off. In the case of daytime, for example, the taxi driver can turn off the light source unit 11 by disconnecting the connecting unit 12 from the wiring 19a between the switching unit 19 and the indicator lamp 13a.

  Further, the configuration of the light source control unit 12 may be other configurations. For example, as illustrated in FIG. 4B, the light source control unit 12 is electrically connected to the light sensor 20 that detects external light and the battery 18, and when the external light is detected by the light sensor 20, When the outside light is not detected by the light sensor 20 when the light sensor 20 is in the cut-off state (OFF state), the first switch 21 that is energized (ON state), and between the first switch 21 and the light source unit 11 And a second switch 22 that is in a cut-off state when the charge maker 17 is operated and is in an energized state when the charge maker 17 is stopped. Even if comprised in this way, it functions as the light source control part 12. FIG.

  Moreover, you may provide the cutting character and the painting character different from the said cutting character in the outer surface or inner surface of the exterior 10. FIG. When the light of the light source unit 11 is projected onto the exterior 10 provided with cutting characters, the color of the exterior 10 is different at night due to the density of the wall surface of the phosphor P (or fluorescent brightener) and the cutting characters. The cutting characters can be raised. In addition, when a normal painting character is provided on the outer surface or the inner surface of the exterior 10, the painting character is displayed during the daytime, and another cutting character different from the daytime painting character is displayed at night. It can be made. Therefore, different advertising characters and messages can be displayed during the daytime and at night.

  EXAMPLES Hereinafter, although an Example etc. demonstrate this invention concretely, this invention is not limited by this.

  First, a plurality of phosphor particles having a particle diameter in the range of 1.2 mm to 2.2 mm, which is made of a transparent acrylic plate and constitutes the hemispherical exterior 10 shown in FIGS. 14 was produced. The phosphor particles 14 emit blue light in response to ultraviolet light. Further, using a known transparent adhesive (epoxy resin), a plurality of phosphor particles 14 are fixed to the inner surface of the exterior 10 by a known method to form a phosphor layer P having a plurality of voids O. It was. At this time, the thickness of the phosphor layer P was set to 2 mm to 3 mm. On the other hand, six light source portions 11 that emit ultraviolet light were prepared and arranged radially from the center of the upper surface of the lid portion 16 as shown in FIG. The light source unit 11 is composed of an electrostatic protection diode, has a DC forward current of 400 mA, a pulse forward current of 500 mA, a reverse voltage of 5 V, an allowable power of 1600 mW, and an operating temperature range. It is in the range of -40 degrees to 100 degrees, and the storage temperature range is in the range of -30 degrees to 85 degrees. The light source unit 11 has a DC forward voltage of 3.3 V, a DC reverse current of 10 μA, a radiant flux of 250 mW, a dominant wavelength of 405 nm, and a half-value angle of 120 degrees. The light source control unit 12 is configured by bundling the wiring 11c of the light source unit 11 and electrically connecting to the wiring 19a between the switching unit 19 of the charge meter 17 of the taxi 13 and the indicator lamp 13a. The row lamp 1 of the Example of invention was created. In this configuration, the taxi driver removes the light source control unit 12 from the wiring 19a during the daytime.

  In the daytime, as shown in FIG. 5 (A), the phosphor layer P of the row lamp 1 reacts with the ultraviolet light contained in the sunlight, and is shining lightly. In addition, as shown in FIG. 5 (B), it is understood that the phosphor layer P of the row lamp 1 emits light with a unique color by ultraviolet light in sunlight, and the presence of the row lamp 1 can be understood slightly. Is done.

  Further, at night, when the vehicle is running empty (standby), the light source unit 11 is turned on, so that the phosphor layer P of the phosphor layer P of the lamp 1 emits blue light as shown in FIG. 6A. And it shines in beautiful blue as a whole. Moreover, ultraviolet light leaks from the space | gap O of the luminous layer P, the brightness | luminance is high as the whole row lamp 1, and the whole row lamp 1 shines strongly and shines. Since the voids O of the phosphor layer P are present in some places, the blue light forms a mottled pattern. In addition, as shown in FIG. 6B, the phosphor layer P of the row lamp 1 shines more strongly in blue than the indicator light of the toll meter, and the brightness of the entire row lamp 1 is clearly high. Understood. Thus, combining the phosphorescent body P with the row lamp 1 makes it easier to attract the user's eyes to the light of the row lamp 1 as compared with other illuminations.

  On the other hand, at night, when the vehicle is running, the light storage unit P is lit by the light-emitting layer P afterglow with a unique color as shown in FIG. It is understood that In addition, as shown in FIG. 7 (B), it is understood that the entire row lamp 1 is difficult to touch the user's eyes because the phosphorescent layer P only shines dimly as shown in FIG. 7B.

  In this way, it can be seen that, at night, the row lamp 1 of the present invention shines completely differently when the vehicle is running empty and when the vehicle is running, and thus has a novelty that attracts the user.

  As described above, the row lamp according to the present invention is useful for a row lamp arranged on the roof of a taxi, and can be easily attracted to the user by making it shine in a unique color at an appropriate timing at night. It is effective as a lantern.
