Description

  The present invention relates to a vehicular indicator lamp that is attached to the exterior of a vehicle body such as a taxi and displays a company name, advertising characters, and the like.

  On the taxi roof, a vehicle indicator lamp is displayed on the surface of a translucent cover body on which signs such as letters and figures indicating company names and advertisements are displayed. Among these, the indicator lamp indicating the company name is turned on when the vehicle is running. Therefore, taxi users can find empty taxis even at night. In the conventional indicator lamp, a light bulb and a fluorescent lamp are installed inside to light up. Patent Document 1 discloses an example of this type of vehicle indicator lamp.

  This indicator lamp is generally equipped with a light source such as a light bulb or a fluorescent lamp inside a synthetic resin cover body, and the company name or company mark using colored paint that does not easily fall on the surface of the cover body. Or, advertisement characters are drawn. Various colors are used as the color of the colored paint, and a company-specific color is used. Alternatively, the entire cover body may be colored blue or yellow. Therefore, when the light source installed inside the cover body emits light, the colored light of the cover body is irradiated to the outside.

Utility Model Registration No. 309181.

  However, the conventional technique has the following problems. For example, FIG. 6 shows a conventional vehicle table indicator lamp 20. In the conventional vehicular indicator lamp 20, light from a light source 27 such as an LED is irradiated toward the cover body 22, but since the light source 27 is installed upward, the light from the light source is directed upward. There is a problem that the amount of light directed toward the direction of the white arrow that is originally desired to be irradiated with light is small and the light is turned on weakly. Further, if the amount of light is increased, the number of light sources must be increased, and the width of the substrate 25 is increased, resulting in an increase in the size of the vehicle surface indicator lamp.

  Accordingly, an object of the present invention is to provide a vehicle surface indicator lamp that can efficiently use light from a light source to reduce the thickness of the vehicle surface indicator lamp itself.

  In order to solve the above-mentioned problem, the vehicle surface indicator lamp (1) according to claim 1 is provided with a pedestal (3) for mounting the vehicle indicator lamp (1) on the roof of the vehicle. In the vehicle indicator lamp (1) that emits light from the light source (7) provided on the board, a plurality of light sources (7) are mounted on both sides, and a circuit board (5) provided with a circuit for lighting the light source (7). The substrate (5) is attached perpendicularly to the pedestal (3).

The vehicle surface indicator lamp (1) according to claim 2 is provided with a reflector (10) mounted on the pedestal (3) and reflecting light from the light source (7) upward.

The vehicle surface indicator lamp (1) according to claim 3 is characterized in that the light sources (7) mounted on both surfaces of the substrate (5) are provided symmetrically with respect to the substrate (5).

The vehicle surface indicator lamp (1) according to claim 4 is characterized in that the substrate (5) is attached at a substantially central position of the pedestal (3).

  The vehicle indicator lamp according to claim 1 includes a plurality of light sources and a substrate for turning on the light sources, and the substrates on which light sources are mounted on both sides are provided perpendicular to the pedestal. The surface on which is displayed is irradiated with light, and the display can be clearly confirmed even from a distance.

  In addition to the effect of the vehicle indicator lamp according to claim 1, the vehicle surface indicator lamp according to claim 2 is provided with a reflecting plate that is mounted on the base and reflects light from the light source upward. Since not only the light directly irradiating the surface on which is displayed but also the light obtained by reflection can be used, the light can be efficiently emitted in all directions.

  In addition to the effects of the vehicle indicator lamp according to claim 1 or 2, the light for the vehicle surface according to claim 3 is mounted on both sides of the board, and the light source is provided symmetrically with respect to the board. Since the light is evenly applied to the surface on which the characters and the like are displayed, the characters and the like can be displayed neatly without unevenness.

  In addition to the effects of the vehicle indicator lamps according to claims 1 to 3, the vehicle surface indicator lamp according to claim 4 is attached to the surface of the pedestal so that characters and the like are displayed on the surface. On the other hand, since light is evenly irradiated, it is possible to display characters and the like neatly without unevenness.

  FIG. 1 is a perspective view showing a vehicular indicator lamp 1 according to this embodiment, in which a company name is displayed on the front surface of a cover body 2. In the present embodiment, the company name part and the hatched part are, for example, parts colored in blue and have translucency. Further, the part other than the company name part and the hatched part are milky white and translucent. Details of the embodiment of the present invention will be described with reference to FIGS.

  2 is a front view of the vehicular indicator lamp 1 according to the present embodiment, FIG. 3 is a cross-sectional view taken along the line AA, FIG. 4 is a front view when the cover body 2 is removed, and FIG. It is a top view in the case.

  As described above, the front and back surfaces (not shown) of the cover body 2 are translucent with the company name and the hatched portion displayed by, for example, blue coloring. Although the both side surfaces, the upper surface, and the front portion of the cover body 2 are translucent, they are milky white so that the inside of the cover body 2 cannot be seen. The cover body 2 is installed so as to cover the periphery of the pedestal 3, and a reflection plate 10 that reflects light is laid on the upper surface of the pedestal 3 so as to be substantially one surface of the pedestal 3.

  Further, as shown in FIG. 3 or 4, two L-shaped angle bodies 6 are attached to the pedestal 3 on the left and right sides of the pedestal 3, and the lower part of the angle body 6 is indicated by a wavy line in FIG. 3. Further, the angle body 6 is embedded and fixed to the pedestal.

  Next, the printed circuit board 5 is fixed to the angle body 6 by screws 9 and attached so as to stand upright by the angle body 6.

  On the printed circuit board 5, a three-color light emitting diode (hereinafter referred to as a three-color LED) 7 and a lighting circuit component 4 for lighting the three-color LED 7 are mounted in a circuit pattern arrangement (not shown). . As shown in FIGS. 3 to 5, the three-color LEDs 7 are mounted on both surfaces of the printed circuit board 5 and are provided symmetrically with the printed circuit board 5 interposed therebetween. As shown in FIG. 4 or FIG. 5, the three-color LEDs 7 are evenly arranged in a line on the surface of the cover body 2 on which the company name portion is described.

  Moreover, the printed circuit board 5 is attached to a substantially central position of the base 3 so that the three-color LEDs 7 are evenly spaced from the front and rear surfaces of the cover body 2 on which the company name portion is described.

  The power cord 8 coming out from the component 4 of the lighting circuit is connected to the vehicle body side (not shown) via a switch or the like.

(Operations and effects in this embodiment)
Next, the operation and effect of this embodiment will be described.
By providing the printed circuit board 5 so as to stand upright with respect to the pedestal 3, light from the three-color LEDs 7 mounted on both surfaces of the printed circuit board 5 is directly in the direction of the white arrow as shown in FIG. Since it can be irradiated, light is directly irradiated onto the surface on which characters (company name portion) are displayed, and the display of characters (company name portion) can be clearly confirmed even from a distance. Moreover, since the printed circuit board 5 including the three-color LEDs can be made thin, the thin vehicle display lamp 1 can be made.

  Further, as shown in FIG. 3, the upper surface of the pedestal 3 is provided with a reflecting plate 10 that reflects light, so that light emitted from the three-color LED 7 is directly reflected toward the reflecting plate 10, The light is reflected by the cover 2 and again reflected by the reflecting plate 10, and the light is reflected upward as indicated by a black arrow. Therefore, not only the direction in which the three-color LED 7 is facing but also light can be efficiently emitted in all directions.

  Moreover, since the printed circuit board 5 including the three-color LEDs 7 is thin as described above, it is possible to provide a space for reflecting light, and it is possible to efficiently use light.

  Further, as shown in FIG. 5, the three-color LEDs 7 are mounted on both sides and are provided symmetrically so as to sandwich the printed circuit board 5, so that light is evenly applied to both sides on which characters are displayed. Since it is irradiated, the characters of the company name on both sides seen before and after the cover body 2 are displayed with uniform brightness without unevenness.

  Further, the printed circuit board 5 on which the three-color LEDs 7 are mounted is mounted at a substantially central position of the base 3 so that the three-color LEDs 7 are evenly spaced from the front and rear surfaces of the cover body 2 on which the company name portion is described. Therefore, the light is evenly applied to both sides of the cover body 2 where the characters of the company name are seen before and after the characters are seen, and the characters and the like are displayed with uniform brightness without unevenness.

(Examples of changes to other embodiments)
The present invention is not limited to the above-described embodiment, and various applications are possible without departing from the scope of the present invention.

In the above embodiment, the three-color LED 7 is used as the light source. However, a fluorescent lamp, a neon tube, a lamp, or the like may be used as long as it emits light.

In the above embodiment, the three-color LEDs 7 are arranged in a straight line, but are not particularly limited, and may be arranged alternately.

In the above embodiment, the three-color LED 7 is installed, but the number is not limited to this. In addition, various dimming controls can be performed by separately providing a dimming circuit or the like, which belongs to the content of the present invention.
