INCORPORATION BY REFERENCE 
       [0001]    This application claims the benefit of Chinese Patent Application No. 201320625763.6, filed Oct. 11, 2013, which is incorporated herein by reference in its entirety. 
       FIELD OF THE INVENTION 
       [0002]    The present invention generally relates to lighting technology, and, more particularly, a work light. 
       BACKGROUND OF THE INVENTION 
       [0003]    Work lights are widely used in automotive repair shops and other repair settings and construction settings. Such work lights are often in a form that can alternatively be handheld or hung from a suitable elevated object such as a raised automobile hood. 
         [0004]    Currently, on the market, most of the work lights require a fixed running power source to power the light bulbs. In the situations such as underwater adventure, camping, road-side car fixing, outdoor living, etc., where a fixed running power source is not available, a self powered and portable work light is desired. 
         [0005]    Even in the traditional settings where work lights have been used, the power cord is a drawback users want to eliminate because it clutters the already cluttered workspace, knocking down and tangling with tools and/or objects in the workspace. Furthermore, running power cord is a hazard if it tangles with and is damaged by a tool. Clearly, a work light without a power cord is desirable. 
         [0006]    Furthermore, unlike incandescent and fluorescent work lights which often comprise at least one glass light bulb, LED work lights are better able to survive falls than are work lights that have glass bulbs. Furthermore, LEDs do not generally operate with parts hot enough to ignite flammable materials, so even falls that do result in breakage are less likely to cause fires than are similar falls of work lights that have glass bulbs. 
         [0007]    The prior art has LED work lights, but because of the running power source requirement, their uses are limited to certain settings, i.e., automobile repair shop, indoor work, etc. Thus, they mostly produce one solid white or yellowish light. Therefore, they are inadequate to use in other settings, such as camping, outdoor games, road-side emergency, outdoor emergency, etc., where a multiple color or blinkable light source is desired to be used as a signal. 
         [0008]    Moreover, in a submerging setting like an underwater adventure, a submerging electrical current is a hazard and a tangled power cord is a serious problem. Thus, most applications of current work lights are on land. Clearly, a cordless, self powered, and portable work light is desirable in these settings. 
       OBJECT OF THE INVENTION 
       [0009]    Accordingly, one objective of this invention is to provide a self powered work light. 
         [0010]    Another objective of this invention is to provide a convenient portable work light. 
         [0011]    Yet another objective of this invention is to provide a versatile work light. 
         [0012]    Yet another objective of this invention is to provide a multiple color work light. 
         [0013]    Yet another objective of this invention is to provide a blinkable work light. 
         [0014]    Yet another objective of this invention is to provide a waterproof work light.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0020]    The following detailed description of the preferred embodiments presents a description of certain specific embodiments as examples of a plurality of ways to practice this invention. As such, one may practice the present invention in a multitude of different embodiments as defined and covered by the claims. 
         [0021]    In some instances, certain features are described in less or more detail. The level of detail associated with each of the elements or features should not be construed to qualify the novelty or importance of one feature over the others. 
         [0022]    Certain marks referenced herein may be trademarks, whose use is to provide an enabling disclosure by way of example and shall not be construed to exclusively limit the scope of the disclosed subject matter to material associated with such marks. 
         [0023]    References in this specification to “an embodiment”, “one embodiment”, “one or more embodiments” or the like, simply mean that the particular element, feature, structure or characteristic being described is in at least one embodiment of the disclosed subject matter. The occurrences of such phrases do not necessarily refer to the same embodiment, nor do they necessarily to mutually exclusive embodiments with respect to the discussed features or elements. 
         [0024]    Various exemplary embodiments disclosed herein are directed to a work light that is convenient, versatile, and waterproof. 
         [0025]    Referring to  FIG. 1 , in one embodiment, a work light comprises a switch cover  1 , which prevents the switch from flipping in the event of a drop. The work light further comprises a strong magnetic ring  3  and a powerful magnet  2 , which are positioned inside the female threaded cavity of the switch cover  1 . The strong magnets can attach the work light to metal objects, fixtures or auto frames. The work light further comprises a Printed Circuit Board (PCB) light board  4 , which is positioned inside a color tube  5 , and their one ends are attached to the switch cover  1  such that the attachment is waterproof, using attaching methods appreciated by a person ordinarily skilled in the art. At the other ends of the PCB board  4  and color tube  5  are attached a powerful magnet  6 , a strong magnetic block  7 , and a handle end  8 . Similarly, the attachment is made waterproof, and the magnets are positioned inside the cavity of the handle end  8 . The strong magnets can also be used to attach the work light to metal objects, fixtures or auto frames. The other end of the handle end  8  is male threaded to receive an O-ring seal  9 , and a female threaded end cap  10 . The O-ring  9  and end cap  10  seal the work light from water and the elements. The cavity of the handle end  8  houses a rechargeable lithium battery. 
         [0026]    Referring to  FIG. 2 , in one embodiment, a work light comprises a switch cover  1 , a color tube  5 , a handle end  8 , and a battery discharge indicator  11 , that has a red, yellow, and green color indicators for a low, half power, and fully charged battery, respectively. The work light further comprises a USB charging jack  12  positioned in the cavity of the handle end  8  and facing the end cap  10 . The USB charging jack  12  is used to charge the rechargeable lithium battery also positioned in the cavity of the handle end  8 . 
         [0027]    Referring to  FIG. 3 , in one embodiment, the work light comprises a switch cover  1  and a push-button switch  13 , which is positioned inside the cavity of the switch cover. It is appreciated that the push-button switch  13  is made waterproof and seals the work light from water and the elements. In one embodiment, the push-button switch  13  can be long pressed to toggle the work light on and off. 
         [0028]    In one embodiment, the PCB LED board  4  has eight light modes, where the first push-button switch  13  click produces a white light, the second click a red light, the third click a green light, the fourth click a blue light, the fifth click a red blinking light, the sixth click a red burst flash light, the seventh click a yellow blinking light, and the eighth click a yellow burst flash light. 
         [0029]    In one embodiment, the PCB LED board  4  has five light modes, where the first click of the push-button switch  13  produces the strongest light in terms of brightness, the second click produces the normal light in terms of brightness, the third click generates mild light to save energy, a fourth click causes blinking light and the fifth click causes excess bright blinking light. 
         [0030]    In one embodiment, the work light can be 6, 8, 10, 12, 15, 18, 24 inches, or longer. It is appreciated that the longer or larger the work light is, the more battery capacity may be required. 
         [0031]    Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement that is calculated or designed to achieve the same purposes may be substituted for the specific embodiments shown. Many adaptations of the disclosure will be apparent to those of ordinary skill in the art. Accordingly, this application is intended to cover any adaptations or variations of the disclosure.
