And a case in which the LED is turned on and off by contacting the outer periphery of the distal end of the spring with the conductive cylindrical portion due to the swing of the spring in the outer peripheral direction.

According to the present invention, it is possible to obtain a light emitting device in which the LED flickers irregularly even if the period of the shake is fast and the shake is made in the horizontal direction, so that the usable range can be expanded.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has a conductive tubular portion having one end connected to a battery and a shape which is loosely fitted into the conductive tubular portion, and a tip end portion connected to an LED at a base side can swing freely. And a connection plate that connects the other end of the battery and the other end of the LED, and a case that covers these members and that can be illuminated when the LED is turned on. The outer periphery of the spring is brought into contact with the conductive cylindrical portion at the outer periphery of the distal end of the spring, and
When the case swings sideways, the tip of the spring provided inside swings, and the outer circumference of the tip of the spring vibrates in a fast cycle state and the The LED is flickered irregularly when it comes and goes, and it has the effect that the range of use can be expanded.

An embodiment of the present invention will be described below with reference to the drawings.

[0010]

(Embodiment 1) As shown in FIG. 1, one end is electrically connected to a battery 1 and the other end is loosely fitted in a conductive tubular portion 3 held by an insulator 2. The LED 4 is electrically connected to the root 5a, and the spring 5 having a tightly wound state of the distal end 5b is held by only the root 5a so that the distal end 5b can swing freely. 3, a connection plate 6 for connecting the other end of the battery 1 and the other end of the LED 4 is provided, and the battery 1, the insulator 2, the conductive cylinder 3,
These members such as the LED 4, the spring 5, and the connection plate 6 are covered with a case 7 in a watertight state. The LED 4 side is formed of a material that can emit light from the LED 4, and the hanging side 8a or a magic tape (see FIG. Mounting means 8 such as not shown)
Is provided.

In the above configuration, when the case 7 swings in the horizontal direction, the distal end 5b of the spring 5 provided in the case 7 swings, and a part of the outer periphery of the distal end 5b of the spring 6 is LE that uses battery 1 as a power source when it contacts inside
The electric circuit of D4 is closed and the LED lights up.

The swing cycle of the spring 5 is fast, and a portion of the outer periphery of the distal end 5b of the spring 6 is immediately disconnected from the inside of the conductive tubular portion 3 to turn off the LED. Of the conductive tube 3 on the opposite side
The LED 4 is turned on by contacting the inside, the LED 4 continues to blink irregularly due to the lateral swing of the spring 5, and the LED is turned off when the swing of the case 7 stops.

[0013] Further, since the winding state of the distal end 5b of the spring 5 is densely formed, the weight of the distal end 5b of the spring 5 is increased, and even small vibration applied to the case 7 is amplified and increased. It operates more sensitively and irregular flickering is more effective.

Further, since the case 7 is formed in a watertight state, it can be used even in the water, and by flashing the LED 4 irregularly in the water, the fish 4
, And can be used as a lure.

Further, since the attachment means 8 is provided in the case 7, it can be provided with an eye-catching decorative effect by being attached to a part of the human body such as ears, wrists, clothes, belongings (sticks and bags), and the like. Not only can it be done, but also the nighttime safety can be ensured by informing the car driver of the presence of a person.

Further, by attaching the LED 4 to various moving objects, irregular blinking of the LED 4 can be effectively used.

According to the light emitting device of the first embodiment, the wound state of the distal end 5b of the spring 5 is described as being dense, but a weight may be attached instead of making the wound state dense. Needless to say.

[0018]

As is clear from the above embodiments, according to the present invention, one end is connected to the conductive tube, and the other end is connected to the LED. A spring connected so that the tip side can swing freely, a connection plate for connecting the other end of the battery and the other end of the LED, and a case that covers these members and can be irradiated when the LED is turned on. And the LED is turned on and off by contacting the outer periphery of the distal end of the spring with the conductive cylindrical portion by the swing in the outer circumferential direction of the spring, so that the cycle of the swing is fast, and the LED is turned by the transverse swing. A small and low-cost light-emitting device that can blink irregularly can be provided.

Further, since the winding state at the tip end side of the spring is made dense, irregular blinking of the LED can be increased and increased.

Further, since the case is constructed in a watertight state,
By moving underwater, the irregular blinking of the LED can attract fish and can also be used as a lure.

Further, since the case is provided with the mounting means, the presence of a person on the car can be shown by mounting the case on the human body, clothes, belongings, etc., and safety at night can be ensured, and it can also be used for eye-catching decoration. .
