As shown in these figures, the light-emitting hula hoop includes a tubular hula hoop body 10 forming a circular ring, a battery 30 installed in the hula hoop body 10, and a longitudinal direction of the hula hoop body 10. A light emitting diode (LED) 20, which is a light emitting element disposed in a plurality of places, and a power supply unit 40 for supplying and cutting off power from the battery 30 to the LED 20.

Hula hoop body 10 may be formed by the combination of the tubular body forming a circular ring, in the embodiment of the present invention, the engaging jaw and hook not shown formed in the battery 30 in a predetermined area along the circumferential direction It is elastically coupled and separated by the piece through the locking and unlocking process.

As shown in FIG. 1, the battery 30 is housed in a battery accommodating portion 31 in which a rectangular cylindrical upper surface provided in the hula hoop body 10 is opened. At both ends of the battery accommodating part 31, ground pieces 37 are formed to elastically contact the battery 30, and each ground piece 37 has a conductive wire 35 connected to the positive electrode of the battery 30. Is provided. The conductive wire 35 transmits power from the battery 30 to the LED 20 to emit the LED 20.

As shown in FIG. 3, the semi-permanent and low power consumption LED 20 includes first and second LED chips emitting an intrinsic color, and an ellipsoid to form an appearance and a carrier 25 to protect each LED chip. ) And a lead 27 for electrically connecting the conductive wire 35 and the LED chip to each other.

The first and second LED chips emit light of different colors. For example, the first LED chip 21 may be formed of a green LED chip emitting green light, and the second LED chip 23 may be formed of a red LED chip emitting red light.

Lead 27 is provided as a conductor, one side is connected to the LED chip and the other side is connected to the conductive wire 35 to transfer the power of the battery 30 to the LED chip. In the present invention, the LED 20 includes the first and the second LED chip, the lead 27 is provided in three strands, the lead 27 in the center is a common terminal, one red terminal, the other one Green terminal. Therefore, each light is red and green are radiated. When both LED chips are energized, red and green are combined to emit orange.

On the other hand, the power supply unit 40, the vibration switch 50 for controlling the on-off of the hula hoop main body 10, and the control unit 41 for supplying and blocking the power from the battery 30 to flash each LED chip It is composed of

The vibration switch 50 is provided between the battery 30 and the controller 41 to be described later to interrupt the power supplied from the battery 30. The vibration switch 50 is interposed between the fixed terminal 51 provided on one side of the conductive wire 35 connected to the ground piece 37 and the conductive wire 35 connected to the control unit 41 to contact the fixed terminal 51. And a movable contact spaced apart and selectively blinking each LED chip.

The fixed terminal 51 has a cylindrical fixed contact 53 for accommodating the movable contact on the inside, an insulating base 45 for supporting the fixed contact 53 and the movable contact, which is manufactured in a disc shape, and the fixed contact 53. It is formed to protrude in the lower region of the fixed contact 53 and includes a grounding portion 43 for electrically connecting the battery.
