Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blinking light driven by a solar cell, and can be used to indicate a dangerous place at a road construction site, for example.

[0002]

[Prior art]

 Conventionally, blinking lights using dry batteries have been used at road construction sites and the like. This type of battery has the disadvantage that the dry battery is consumed quickly and the maintenance cost is high. Moreover, it is troublesome to operate the power switch in the morning and evening.

[0003]

[Problems to be solved by the device]

 The purpose of this invention is to obtain a flashing lamp that does not require battery replacement by using a solar cell.

[0004]

[Means for Solving the Problems]

 The flashing light of this invention has a solar panel facing up inside an umbrella in a mushroom-shaped case. The storage battery that stores the electric power obtained from the solar cells when the surroundings are bright is housed in the handle of the mushroom-shaped case. A light-emitting element that blinks with the power supplied from the storage battery when the surroundings become dark is placed inside the umbrella under the solar cell panel so that light can be emitted from around the umbrella.

A spring, which is compressed by the inner wall of the tubular body, can be attached to the lower end of the handle so that the handle of the mushroom-shaped case does not come out easily when it is inserted into the tubular body. It is advisable to place a scattering plate around the light emitting element, the surface of which has fine irregularities. It is preferable that the upper surface of the umbrella of the mushroom-shaped case is formed in a dome shape, that is, a hemispherical shape so that bird droppings do not adhere to it.

[0006]

With this signal light, the electric power obtained from the solar cell is stored in the storage battery when it is bright in the daytime. When the surroundings get dark, the light-emitting element blinks with the power supplied from the storage battery.

[0007]

【Example】

 An embodiment of this invention will be described with reference to the drawings. The case 1 of the flashing lamp is formed by adhering a dome-shaped cover 1c via a ring 1b on a cylindrical main body case 1a, and is shaped like a mushroom. The main body case 1a is made of red acrylic resin and has a light-transmitting property. A very small hole 3 is formed in the portion corresponding to the back side of the mushroom umbrella 2 in order to allow the gas from the storage battery to escape.

The dome-shaped cover 1c is made of transparent acrylic resin, and four receivers 4 are integrally molded inside the dome-shaped cover 1c, and the solar cell panel 5 is adhesively supported on these receivers.

The inside of the main body case 1 a is partitioned by two circular plates 7 and 8 to form a light emitting chamber 9, and a light emitting diode 10 is placed therein. A scattering plate 11 is attached to the inside of the wall surrounding the light emitting chamber 10. The scattering plate 11 is a transparent plastic plate in which grooves are cut vertically and horizontally (FIG. 2), and light emitted from the light emitting diode is scattered in all directions. A substrate 12 on which electronic components are placed is arranged below the lower disk 8.

Two nickel cadmium storage batteries 14 are housed in the handle 13 of the main body case. An operation switch 15 is attached to the bottom of the handle 13. Further, the W-shaped leaf spring 16 is screwed.

FIG. 4 is a block diagram of an electric circuit. When the surroundings are bright, a charging current flows from the solar cell 5 through the backflow prevention diode 17 to the nickel-cadmium storage battery 14. When the surroundings become dark and the electromotive force of the solar cell 5 drops, the sunshine discrimination circuit 18 detects this, activates the transmission output circuit 19, and the light emitting diode 10 blinks. When the light emitting diode 10 blinks, the light hits the scattering plate 11 and is refracted and reflected in a complicated manner, and the light spreads uniformly in the direction of 360 degrees and goes out. If the operation switch 15 is turned off, the battery can be charged, but the light emitting diode does not blink.

As shown in FIG. 5, for example, this blinking lamp is installed at a construction site or the like by inserting a portion of the handle 13 into a stand-type cylindrical body 21. When inserted into the tubular body 21, the W-shaped leaf spring 16 contracts as shown by the chain line in FIG. 1 and cannot be easily removed.

[0013]

[Effect of device]

 As explained above, this invention has the following effects. The flashing lamp according to claim 1 has a mushroom-shaped case, and the handle portion can be inserted into a tubular shape and simply installed anywhere. Moreover, since the solar cell is housed in the mushroom-shaped case under the umbrella, the sunlight can be received efficiently. Further, since the light emitting element is arranged in the umbrella under the solar cell, the blinking light can be sent out to 360 degrees around and no blind spot occurs. Also, since the storage battery is housed in the handle, the volume in the case can be used without waste.

In the blinking lamp of the second aspect, the spring is attached to the lower end of the handle, so that when the handle is inserted into the tubular body, it is difficult to easily remove and also theft is prevented. In the blinking lamp of claim 3, a light-emitting element is provided with a scattering plate around the surface of which fine irregularities are formed. The light emitted from the light-emitting element is scattered in all directions, and the light around the light-emitting element is surrounded. The case wall can be illuminated evenly. Further, it can be manufactured at a lower cost as compared with the case where unevenness is formed on the wall of the main body case itself.

According to a fourth aspect of the present invention, the upper surface of the umbrella of the mushroom-shaped case is formed into a dome shape, and bird feces are less likely to adhere to the umbrella than in the case of a flat surface.
