Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of warning equipments, and more particularly to a portable multi-functional light emitting device with a small volume, full functions and easy-to-carry features, and having a light guide member with different functions for different purposes.

2. Description of the Related Art

For outdoor activities, we generally carry various types of illumination devices with us for the illumination and emergency situations, and the illumination devices of this sort include head lamp, flash light and spot light or any other neon lamp with special illumination functions. These illumination devices come with different sizes and volumes. For the large-sized spot light or neon light, it is inconvenient to carry, and most of the present portable illumination devices are primarily head lamps and flash lights.

As disclosed in U.S. Pat. No. 7,740,368 B2 entitled “Cap with a light emitting diode (LED) for illuminating a beverage container”, the LED illuminating cap applied in the beverage container comprises a lens, an LED light source, a battery, a control circuit board, a control button and a transparent chassis. The LED light source is installed between the cap and the lens, so that the LED light source is positioned downwardly for projecting light towards the lens, and the control circuit board is powered on by the battery to drive the LED light source, and the control button is installed at the cap, and the transparent chassis serves as the base of the lens. The transparent chassis is detachably coupled to the beverage container for the illumination purpose.

However, the LED illuminating cap is applicable to a general beverage container only. With the concave-and-convex design of the surface of the beverage container and the refraction/reflection of the beverage, light is illuminated. However, such arrangement still has the drawbacks of low power endurance and inconvenient change of battery. In addition, users need to carry a beverage container for its use, and thus causing inconvenience to users.

In view of the aforementioned problems of the prior art, it is a primary objective of the present invention to provide a portable multi-functional light emitting device, wherein a first cover and a second cover are engaged with each other, covered by an illumination module, and installed onto a light guide member such as a PET bottle or a circular rod. The illumination module generates different lights for the purposes of illumination, warning or decoration and projects the lights to the light guide member, so as to improve the convenience of use significantly. In addition, a keychain is installed to a surface of the first cover to facilitate users to carry the keychain. The second cover may have a rib disposed on a surface of the second cover to facilitate users to change to a different light guide member.

To achieve the aforementioned objective, the present invention provides a portable multi-functional light emitting device, comprising: a first cover, including a first connecting portion disposed at an end of the first cover, a second connecting portion disposed at the other end of the first cover, and a ring-shaped retaining wall disposed between the first connecting portion and the second connecting portion; a transparent waterproof cover, including a ring-shaped flange corresponsive to the ring-shaped retaining wall and provided for embedding into the first cover, and a waterproof silicon ring clamped between the ring-shaped flange and the ring-shaped retaining wall, so that an accommodating space is formed after the first cover and the transparent waterproof cover are combined; an illumination module, installed in the accommodating space, and comprised of at least one LED light source, a control circuit board and a power supply, and the LED light source and the power supply being electrically coupled to the control circuit board, and the control circuit board having a switch for controlling an illumination status of the LED light source; a second cover, including a third connecting portion disposed at an opening of the second cover and corresponsive to the first connecting portion and provided for covering and sealing a side of the first cover, and the second cover, and a penetrating hole corresponsive to the switch; and a light guide member, including a fourth connecting portion disposed at an end of the light guide member and corresponsive to the second connecting portion and provided for combining the light guide member and the first cover as a whole, and the illumination module is provided for driving the light guide member to emit light.

In a preferred embodiment, the light guide member is a PET bottle, and the third connecting portion is a thread corresponsive to the PET bottle and provided for screwing the first cover onto the PET bottle. With the waterproof design of the present invention, the PET bottle provides illumination light for camping after it is filled with water. In addition, the present invention also provides a design with an adapter ring to fit different sizes of the PET bottles, wherein the adapter ring has an outer thread portion disposed at an outer portion of the adapter ring and corresponsive to the third connecting portion, an inner thread portion disposed at an inner portion of the adapter ring and corresponsive to the PET bottle, so that the adapter ring may be screwed between the first cover and the PET bottle for installing the PET bottle of a different size.

In another preferred embodiment, the light guide member is a circular-rod structure and made of a translucent material, and the light guide member includes a light collecting portion disposed at an end of the fourth connecting portion, and a refracting/reflecting portion disposed at the other end of the fourth connecting portion. The light guide member provides an illumination effect like a flash light or a warning effect like a warning rod.

In the portable multi-functional light emitting device of the present invention, a charging port is provided for the charging purpose, wherein the charging port is installed on a surface of the second cover and electrically coupled to the power supply for charging the power supply without the need of changing the battery frequently, and the charging port may be combined with a general mobile power supply for use. The charging port is one selected from the collection consisting of USB, MINI USB and MICRO USB ports.

To facilitate users to carry, the portable multi-functional light emitting device of the present invention further adds a keychain, and a holding portion is protruded from the second cover, and the holding portion has a through hole for coupling the keychain, so that the keychain may be worn onto a user's body or backpack. In addition, the keychain is comprised of a first collar, a winding box and a second collar, and the first collar is coupled to a surface of the winding box, and an extending sling is disposed around the interior of the winding box, and the second collar is coupled to an end of the extending sling, so that the second collar is capable of stretching or retracting with respect to the winding box to facilitate users to extend the length of the keychain for use or reduce the length for an easy storage.

The illumination module includes a first LED light source, a second LED light source and a third LED light source, and the switch is provided for switching to a different LED light source to emit a different light. For example, the first LED light source is a white light LED for emitting white light, the second LED light source is a yellow light LED for emitting a yellow light, and the third LED light source is a polymorphic LED for emitting different color lights alternately.

To facilitate users to change to a different light guide member, at least one rib is formed at an outer surface of the first cover for increasing the resistance of the rotation, so as to facilitate the users to change the light guide member.
