Description

Self-illuminating device {LIGHT SELF-EMITTING APPARATUS}

The present invention relates to a self-light emitting device that can serve as a night light or a safety light using a light source, in particular an LED, which is emitted by a self-emitting assembly that generates electricity by contacting and rotating a rim of a bicycle wheel.

More specifically, even if the road surface is uneven or the road surface is uneven, the impact surface of the light-transmissive shell in which the self-luminescent assembly is integrated is always in constant contact with the rim. A pair of crown gears which are constantly engaged by elastic means are provided in the mounting means connected to the fixed object such as the bicycle fork and the light-transmissive outer shell, respectively.

In addition, when the self-light emitting device is not used during the day, the outer shell may be detached from the rim by changing the engagement position of the pair of crown gears.

Furthermore, the present invention relates to a self-light emitting device that can be used semi-permanently by using a LED as a digital light source to improve the visibility due to the afterimage effect and to easily configure a protection circuit to block the energization when an overcurrent occurs in the self-emitting assembly.

The technology that is used as night light by self-power generation and light emission by receiving rotation power of bicycle wheel rim,

In Korea, many improved technologies have been proposed, including Utility Model Registration No. 0006896 (1986.08.10), “Generator Lubricant Case for Bicycles,” based on the principle of power generation using magnet stators and rotors.

In addition, the technology that allows the roller and the wheel rim of the self-luminescent assembly, which is mainly connected to the clamp fixed to the fork of the bicycle, to be in contact or non-contact, is published in Utility Model Publication No. 1990-0001360 (1990.02.26). As shown in Fig. 2, it was common to use a torsion coil spring fitted to a coupling pin connecting the clamp and the self-luminescence assembly.

On the other hand, with the development of technology and diversification of leisure culture, self-luminous devices have achieved miniaturization, light weight and durability.

The development of such a self-luminous device is engaged with the activation of inline skating on one side, and a number of in-line skating, including patent registration No. 0291213 (2001.03.08) `` Small wheel generator and light-emitting wheel with the same and its manufacturing method ''. Industrial property rights related to the light emitting wheel are shown.

As a safety or lighting technology applied to bicycles, utility model registration No. 0271638 (2002.03.29) related to being installed on the rear wheel or front wheel shaft of bicycle, `` Bicycle light emitting device using inertial disc '' and patent registration No. 0731612 (2007.06.18) ) "Light emitting device for rotating body"

5) Referring to FIG. 4, the contact surface portion 10 is in contact with the rim 1 according to the surface curvature of the rim 1 which is impacted by the surface curvature or the ground condition of the rim 1 itself of the bicycle. To be maintained,

5-1) When the first mounting means (A) is mounted on the rim (1) of the bicycle, the engagement relationship between the fixed bundle 30 and the crown gears 32 and 41 of the tension arm 40 is a normal interlocking relationship with each other, That is, each mountain is in a state of being engaged with each other so as not to be displaced. (See FIG. 4A).

5-2) In the convex area of the rim 1, the fixed bundle 30 and the crown gears 32 and 41 of the tension arm 40 are staggered from each other. That is, the crown gear 32 of the fixed bundle 30 in the crown gear 41 of the tension arm 40 is staggered in the outward direction of the rim. The staggered crown gears 32 and 41 are exerted in the direction in which the crown gears 32 and 41 are engaged by the elastic means (B).
