Description

  The present invention mainly relates to a running light that is preferably used as an advertisement light, a sign light, or an illumination light.

Conventionally, as this type of running horselight, there is an illumination lamp such as a light bulb, a gas lamp, and an arc lamp on a required base, and a translucent inner cylinder with a rotatable running horse picture surrounding the illumination lamp, A translucent outer cylinder surrounding the inner cylinder is sequentially arranged concentrically, and the inner cylinder has a basic structure in which a top plate provided with an exhaust port and a blade is attached to the upper end of the inner cylinder. (See Japanese Utility Model Publication Nos. 62-164312, 2-37700, and 4-25105).
The conventional running light having the basic configuration as described above turns on an illuminating lamp such as an electric lamp to generate light and heat in the inner cylinder, and the generated heat causes an upward air flow in the inner cylinder and rises. The inner cylinder is rotated by applying airflow to the blades in order to cause the inner cylinder to rotate, and a running horse picture is rotated and projected onto the outer cylinder.

  By the way, the above-mentioned conventional running light uses the heat generated by an illumination lamp such as a light bulb, gas lamp, arc lamp, etc., to rotate the inner cylinder. This takes time, and not only the initial rotation of the inner cylinder is slowed down, but also when the inner cylinder is rotated, the rotation speed depends on the temperature of the outside air and is always stable at a constant speed. It is difficult to rotate. In addition, illumination lamps such as a light bulb, a gas lamp, and an arc lamp have high heat generation characteristics, and thus have problems in terms of energy saving and life. For this reason, it is conceivable to use low heat generation lighting lamps such as recent low heat generation bulbs and low heat generation fluorescent lamps, but these low heat generation lighting lamps are suitable for the inner cylinder because of their low heat generation. Ascending air current cannot be generated and it cannot be adopted and used.

  The present invention solves the problems of the prior art, and not only can the initial rotation operation of the inner cylinder be performed quickly and surely, but also the inner cylinder is always at a constant speed regardless of the temperature of the outside air. It is possible to stably rotate, project a running horse picture on the outer cylinder, and to save energy and increase the life by using a low heat-generating lighting such as a low heat-emitting fluorescent lamp if necessary. It is intended to provide a running horse light.

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention comprises a required illuminating lamp on a hollow base, a rotatable translucent inner cylinder with a running horse picture surrounding the illuminating lamp, A translucent outer cylinder surrounding the inner cylinder is sequentially arranged concentrically, a top plate having an exhaust port and a blade body is attached to the upper end portion of the inner cylinder, and a ventilation hole is provided in the base The gist of the present invention is a running lamp characterized by having a fan that blows air into the inner cylinder and rotates the inner cylinder while being applied to the blades.

  The invention according to claim 2 is characterized in that the base is formed with a required air intake hole in order to allow air between the inner cylinder and the outer cylinder to be sucked in by the fan. This is a summary of the running horse light.

The invention described in claim 3 is the running horse light according to claim 2, characterized in that a closing plate is attached to the outer cylinder so as to close the upper end portion thereof.

Since the invention according to claim 1 is configured as described above, the illuminating lamp is turned on, the fan is rotated, the air is blown into the inner cylinder through the blower holes, and the inner air is exhausted while sequentially hitting the blades. Compared to the conventional example in which the cylinder is rotated, and the running horse picture can be rotated and projected on the outer cylinder. Not only can the initial rotation of the inner cylinder be performed quickly and reliably, but the inner cylinder can be stably rotated at a constant speed regardless of the outside air temperature. It can be projected onto the outer cylinder, and if necessary, low heat generation lamps such as low heat generation fluorescent lamps can be used to not only save energy but also significantly increase the life of the lamps. It is.

Since the invention according to claim 2 is configured as described above, the air between the inner cylinder and the outer cylinder is sucked into the base from the intake hole to smoothly rotate the fan. I can do it.

Since the invention according to claim 3 is configured as described above, the air flow can be circulated among the base, the inner cylinder, and the inner and outer cylinders by the air blowing operation of the fan. The hot air flow generated by the heat generated by the illuminating lamp can be used effectively without escaping to the outside, and the load on the fan can be reduced.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on an embodiment shown in the drawings.

1 to 3 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a substantially elliptical hollow base having a required width and height, and 2 denotes a center on the base 1. An illumination lamp made of a tube-type fluorescent lamp standing upright and having a required height, 3 is a translucent inner cylinder having a required outer diameter fitted to surround the illumination lamp 2, The cylinder 3 is provided with a required running horse picture (not shown) such as a cutout on its outer surface, and is supported on the top of the illuminating lamp 2 via a pivot bearing mechanism 4 so as to be rotatable concentrically. 5 is a top plate constituting the inner cylinder 3, 6 is an exhaust port formed radially on the top plate 5 at a predetermined pitch, and 7 is a blade formed upright along one side edge of each exhaust port 6. The body 8 is a translucent outer cylinder that is erected on the outer peripheral edge of the base 1 through a pair of pillars 9 on both sides to surround the inner cylinder 3, and 10 is a base that is positioned below the inner circumference of the inner cylinder 3. The required number of air blowing holes 11 formed concentrically on the upper wall of the base 1, and the required number of air holes 11 formed concentrically on the upper wall of the base 1 to be positioned between the inner cylinder 3 and the outer cylinder 8. The intake holes 12 are fans that are rotatably disposed in the base 1 in order to suck air from the intake holes 11 and blow the air into the inner cylinder 3.

Next, the operation of the embodiment configured as described above will be described.
First, the illumination lamp 2 is turned on and the fan 12 is rotated. As the fan 12 rotates, the air is sucked into the inner cylinder 3 through the air holes 10 while being sucked from the air holes 11, and the inner cylinder 3 is rotated in a predetermined direction while being sequentially applied to the blade body 7 and exhausted from the exhaust port 6. The running horse picture of the inner cylinder 3 is rotated and projected onto the outer cylinder 8.
At this time, the inner cylinder 3 is rotated through the blade body 7 by the air blowing action of the fan 12, so that the initial rotating operation of the inner cylinder 3 can be performed quickly and reliably as compared with the conventional example. In addition, the inner cylinder 3 can be stably rotated at a constant speed without being influenced by the temperature of the outside air, and a running picture can be projected and projected onto the outer cylinder 8 at a constant speed. The lamp 2 can be effectively selected and used not only with high heat generation but also with low heat generation.

  FIG. 4 shows another embodiment of the present invention, which is different from the above embodiment in that a closing plate 13 is attached to close the upper end portion of the outer cylinder 8, and the other portions are the same and the same. The code | symbol shows the same part.

  In the embodiment configured as described above, the illuminating lamp 2 is turned on, and the fan 12 is rotated to suck air from the air intake hole 11 and into the inner cylinder 3 from the air blow hole 10 in the same manner as the above embodiment. The inner cylinder 3 is rotated in a predetermined direction while being blown and sequentially applied to the blade body 7 and exhausted from the exhaust port 6, and a running horse picture of the inner cylinder 3 is rotated and projected onto the outer cylinder 8. At this time, since the upper end portion of the outer cylinder 8 is closed by the closing plate 13, the rotation of the fan 12 causes the inside of the base 1, the inner cylinder 3, and the inner and outer sides to pass through the blower hole 10, the exhaust port 6, and the intake hole 11. The air flow can be circulated between the cylinders 3 and 8, and the thermal air flow generated by the heat generated by the illumination lamp 2 can be effectively used without escaping to the outside, and the load on the fan 12 is reduced. It can be damned.

  In the above embodiment, the illuminating lamp 2 is made of a tube fluorescent lamp. However, the illuminating lamp 2 is not limited to this, and a known illuminating lamp such as a light bulb or a light using an LED can be adopted and used. In addition, such an illumination lamp can be appropriately used not only with a high exothermic property but also with a low exothermic property. The running horse picture to be formed on the inner cylinder 3 is not limited to a cutout picture, but a similar running horse picture or a required picture or pattern may be engraved on the outer surface of the inner cylinder 3 itself.
