DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signal light for use in traffic control, road construction sites, parking lots, and the like.

[0002]

2. Description of the Related Art In a conventional signal lamp, a transparent cylinder having a light source which emits light by the power supply is continuously provided at a gripping portion containing a power supply such as a battery. A red retroreflective synthetic resin sheet is attached to the inner peripheral surface of the body so that the transparent cylinder shines reddish by the transmitted light from the light source.

However, it has been found that it is difficult for a driver of a vehicle or the like to actually confirm the presence of a single red-colored brilliance by such a signaling light, and that the signaling is not sufficiently transmitted.

The present invention has found such a problem, and the distal end of the transparent cylindrical body is configured to shine red, and the base end of the portion shining red is configured to shine white. The present invention provides an epoch-making signal light in which the red bright portion is very conspicuous and the visibility is extremely good.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

A light transmitting cylinder 4 having a light source 3 illuminated by the power supply 1 is continuously connected to a tip end of a grip portion 2 having a power supply 1 such as a battery therein, and the light source 3 is attached to the light transmitting cylinder 4. In the signaling lamp in which the light-transmitting cylinder 4 forms a red luminous portion 5 that shines in a red color due to the transmitted light from the light-transmitting cylinder 4, the light-transmitting tube 4 does not have the red luminous portion 5 formed on the entire surface. The intermediate portion or the base end of the cylindrical body 4 forms a white brilliant portion 6 in which the intermediate portion or the base end of the light-transmitting cylindrical body 4 shines in a white color by the transmitted light from the light source 3. The distal end of the cylindrical body 4 is configured to shine in red by the red brilliant portion 5, and the base end side of the portion shining in red is brilliant in white by the white brilliant portion 6. It is related to a signal light to be performed.

[0007] A transparent cylinder 4 having a light source 3 for emitting light from the power supply 1 is continuously connected to a front end of a grip portion 2 containing a power supply 1 such as a battery. A red retroreflective synthetic resin sheet 7 attached to the light source 3
In the signaling lamp in which the transparent tube 4 forms a red brilliant portion 5 in which the transparent tube 4 shines in a red color by transmitted light from the transparent tube 4, the transparent tube 4 is not formed on the entire surface of the transparent tube 4, A white retroreflective synthetic resin sheet 7 is attached to the inner peripheral surface of the intermediate portion or the base end of the transparent cylindrical body 4 so that the intermediate portion or the base end of the transparent cylindrical body 4 is white based on the transmitted light from the light source 3. Forming a white brilliant portion 6 shining on the transparent cylindrical body 4
The front end portion is configured to shine in red by the red brilliant portion 5, and the base end side of the portion shining in red shines in white by the white brilliant portion 6. It relates to the signal light described in 1.

[0008]

Conventionally, the entire surface of the light-transmitting cylinder shines in a single red color due to the transmitted light of the light source. However, in the present invention, the tip of the light-transmitting cylinder 4 is formed in a red luminous portion 5 shining in a red color. Since the middle portion or the base end portion of the light transmitting cylinder 4 is formed in the white brilliant portion 6 that shines in white color, when the light source 3 emits light, the transmitted light of the light source 3 causes the light transmitting cylinder 4 to emit light. The red glitter portion 5 at the distal end of the light-transmitting cylindrical body 4 shines red, and the white glitter portion 6 at the middle or base end of the light-transmitting cylindrical body 4 shines white.
Therefore, the red glitter portion 5 and the white glitter portion 6 on the base end side of the red glitter portion 5 simultaneously shine, so that the glitter of the red glitter portion 5 on the distal end is closer to the proximal end compared to the single-color glitter. Of the white brilliant part 6 of the luminous body 6, the surface becomes very conspicuous, and the visibility becomes extremely good.

[0009]

In the drawing, a battery (power supply 1) is accommodated in a grip portion 2, and a circuit board for driving a light source 3 (not shown) is provided at the tip of the grip portion 2. A light source mounting plate connected to the substrate is protruded into a light transmitting cylinder 4 connected to the grip portion 2, and a plurality of LEDs as light sources 3 are provided on the light source mounting plate.

The "light source 3 is included" in the first embodiment means that the light source 3 is provided inside the light-transmitting cylinder 4 as in this embodiment, and the light source 3 3 is fixed, and the light from the light source 3 is guided or reflected into the light-transmitting cylinder 4 to be guided into the light-transmitting cylinder 4, and the light-transmitting cylinder 4 may be illuminated in an indirect case. It is a thing.

The translucent cylinder 4 is preferably a plastic cylinder.
A locking flange is formed on the outer periphery of the base end of the light-transmitting cylindrical body 4, and a plastic tightening cylinder 8 is fitted and adhered on the locking flange, and the tightening cylinder 8 is attached to the distal end of the grip portion 2. Light transmitting cylinder 4
Is shown in the case of being detachably provided on the grip portion 2.

The drawing shows a case where the retroreflective synthetic resin sheet 7 is formed in a cylindrical shape, and the cylindrical retroreflective synthetic resin sheet 7 is adhered to the inside of the light transmitting cylinder 4. A red retroreflective synthetic resin sheet 7 that shines red by the transmitted light of the light source 3 is disposed on the front end side of the light transmitting cylinder 4 at a substantially middle portion as a boundary, thereby forming a red luminous portion 5. On the base end side, a white retroreflective synthetic resin sheet 7, which also shines white by the transmitted light of the light source 3, is arranged to form a white brilliant portion 6.

The "white system" described in claim 1 includes not only white but also those belonging to the yellow system. When the white system comes into contact with the red system, the red system shines. Things.

Accordingly, when the light source 3 emits light, the red glitter portion 5 at the tip of the light transmitting cylinder 4 shines red, and the white glitter portion 6 on the base end side of the red glitter portion 5 becomes white. It will shine.

The red glitter portion 5 and the white glitter portion 6 can be formed without using the retroreflective synthetic resin sheet 7 as in this embodiment.
The light transmitting cylinder 4 itself may be made of a retroreflective resin material used for tail lamps of automobiles or the like, and the tip may be of a red type and the base may be of a white type.

Further, in the present embodiment, the ratio of the arrangement area of the red luminous part 5 and the white luminous part 6 is configured to be approximately 1: 1.
The area of the red glittering portion 5 may be increased, and the ratio of the arrangement area of the red glittering portion 5 and the white glittering portion 6 occupied in the light transmitting cylinder 4 can be appropriately designed. Further, for example, as shown in the explanatory view of FIG.
May be arranged in “red / white / red”, “white / red / white”, etc., but a white luminous portion 6 is always arranged at the base end side of the red luminous portion 5, and this white The red brilliant part 5 by the brilliant part 6
Make it stand out.

[0017]

Since the present invention is constructed as described above, when the light source emits light, the red brilliant portion of the light-transmitting cylinder shines red, and the white brilliant portion shines white. The brightness of the red shining part on the tip side becomes very conspicuous due to the shine of the shining part, and the visibility is significantly improved compared to the conventional product that shines only one red color, and good signal transmission is possible. An epoch-making signal light can be provided.
