Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held light emitting device which is used mainly for improving the visibility of a user in darkness or dusk, and in particular, the light emitting portion is formed in an annular shape. It relates to a light emitting ring.

[0002]

2. Description of the Related Art Conventionally, a grip member is attached to a rod-shaped luminous body in order to give a warning to a passerby by a police officer or to improve the visibility of an actor in a dark stage.
A club-shaped handheld light emitting device is known. In addition, a light bulb is hung on the display fence to illuminate it in order to display the recesses formed on the road at night due to road construction.

[0003]

However, since the conventional light emitting device itself is large and the light is directly emitted from a large light source, there is a problem that the dry battery serving as a power source is largely consumed. Also, in the case of using a commercial power source to prevent the consumption of dry batteries, it is necessary to connect the electric wires at the time of use, which makes it inconvenient to carry and handle. Furthermore, there is a problem that it takes time and effort to install them, such as the need for a support and wiring to install them on the ground.

[0004]

The above-mentioned problems are solved by supporting a power source, a light source, and a switch connecting and disconnecting them inside a supporting housing, and transmitting light from one side and the other side of the supporting housing. This is solved by inserting one end and the other end of a light emitting bar made of a conductive material, and making both ends thereof face the light source inside the support housing. In particular,
The light emitting bar is composed of an elongated tube made of a flexible synthetic resin and a diffusely reflecting filling material filled therein. A battery is used as the power source and an LED is used as the light source. The light source is not limited to the light emitting element, and may be a miniature electric bulb, but the light emitting element is superior in that it consumes less power.

[0005]

The transparent light-emitting bar has both ends supported by the support housing or is connected to form a ring. When the switch provided on the support housing is operated to emit light and the light source emits light, the entire amount of the light immediately enters the inside of the light emitting bar from the end, diffusely reflected by the filling material filled therein, and the rod-shaped member itself emits light. It becomes a light emitting ring. Also, by hooking the ring-shaped light emitting bar on a support such as a pylon installed on the ground, the bar can be installed at a desired location.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In the figure, 10 is a light emitting ring according to the present invention.
The light emitting ring 10 includes a support housing 20 and a ring-shaped light emitting bar 30 attached to the support housing 20. The support housing 20 is made of a synthetic resin by injection molding to have a small box shape, and its opening is closed by a lid 21 so as to be openable and closable.
Reference numeral 22 denotes a locking tongue, which is provided inside the lid body 21. Thus, when the lid 21 is put on the support housing 20,
The locking tongue 22 is pressed into the inner surface of the support housing 20 in a compressed state, and presses the locking tongue 22 so that the lid 21 is supported by the frictional force.
It is locked at 0.

Inside the support housing 20, two AA batteries 23 as a power source and an LED (light emitting element) 24 as a light source are provided.
Also, the switch 25 and the like are housed in an electric wire (not shown) that connects them. Switch 2
5 is a snap type, elastic hook 25a provided on the side surface
Is locked to the edge of the through hole provided on the wall surface of the support housing 20, and the operation surface is directed to the outer surface.

The light emitting bar 30 is made of a transparent material, that is,
Diameter of about 10m made of transparent and flexible synthetic resin
It is composed of an elongated tube 31 of m and a light-diffusive reflective material 32 filled inside. As the light diffusely reflecting filler 32, a gel-like (or agar-like) silicone rubber 33 having a light transmitting property is used. Since the silicon rubber 33 is almost transparent and has a light scattering property, when it is irradiated with light, it emits light as a whole. Therefore, when light is applied to the end face of the elongated tube 31 which is the light emitting bar 30, the light is emitted from the tube 31.
Emits light of the same color as the light source over the entire length of.

In this embodiment, the light emitting ring 10 is formed by bending the light emitting bar 30 into a circular shape having a diameter of about 10 to 15 cm, and inserting the ends of the light emitting bar 30 from one side and the other side of the support housing 20 to fix the same. There is. That is, as shown in FIG. 2, through holes 26, 26 having a diameter slightly smaller than that of the tube 31 are provided on one side and the other side of the support housing 20, and the end portion of the light emitting bar 30 is pressed and contracted therein. It is pushed in in the closed state. In addition, if necessary, insert a retaining tube 27 shown by a chain double-dashed line in the drawing from the inside, and loosely contact the end surface of the tube 31 with the side surface of the light emitting element 24 through the retaining tube 27. is there.

Thus, when the switch 25 is turned on,
The LED 24, which is a light source, emits a predetermined color such as red, green, or yellow. The light emitted from the light source 24 enters from the end surface of the elongated tube 31, and is reflected by the inner surface of the tube 31, and travels in the longitudinal direction. That is, the silicone rubber 33
While traveling in the interior of the tube, a part thereof is diffusely reflected according to the characteristics of the silicone rubber 33, and a part of the tube 13 which is bent at an angle close to a right angle to the inner surface of the elongated tube 31 is included in the tube 13.
The light is emitted to the outside without being reflected on the inner surface of the
0 is emitted.

FIG. 4 shows an example of use of the light emitting ring 10. That is, the light emitting ring 10 is turned on, and the light emitting ring 10 is lit and hung on the pylon P or other support installed on the road to display a road construction site or a road surface frozen spot.

[0012]

As described above, according to the present invention, since the main part of the light emitting ring 10 is composed of the support housing 20 made of synthetic resin and the light emitting bar 30, the light emitting ring 10 is lightweight and easy to carry. . Further, since the light emitted from a small light source is emitted from a large area by the light emitting bar 30 formed of the synthetic resin thin tube 31 and the filling material 32, it is possible to provide effective illumination and signal means with low power consumption. In addition, it can be easily hooked to and supported by a support such as a pylon due to its annular shape, and since no expensive parts are used for manufacturing these, it can be manufactured inexpensively as a whole. There is an effect such as being able to.
