Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates generally to a lighting apparatus and mounting assembly for mobile vehicles, and more particularly to a pivotable light apparatus with light emitting diodes (LEDs), integral USB charger and universal mounting assembly which is mountable in various configurations of a mobile vehicle including the method of illuminating, making and operating the same. 
         [0002]    The primary purpose of a light assembly on mobile vehicles such as bicycles is to provide illumination and conspicuity for the cyclist. Light assemblies aid the cyclist in seeing the road ahead of them at times of day and night when there is not enough ambient light to safely ride a bicycle and also allow the cyclist to be seen by oncoming motorists. 
         [0003]    In the prior art, light assemblies have used a single beam of light, which limited the field of vision due to the small size of the single beam of light. For cyclists riding at night, particularly at higher speeds, it is advantageous to have more light and a wider-angle beam than that of a single beam. 
         [0004]    Another disadvantage of the prior art was the difficulty of charging the power supply to the light assembly. The cyclist would have to carry spare batteries as a backup in case of power loss. 
         [0005]    Another important feature in light assemblies is the ease with which the apparatus can be mounted and dismounted on a mobile vehicle, such as a bicycle. This is often necessary when a cyclist has two or more bicycles and does not want to purchase a dedicated light for each bike or if the cyclist wants to remove only the light assembly from the bike for example due to fear of theft of the light assembly. 
         [0006]    Therefore it is desirable to provide a pivotable LED light apparatus with light emitting diodes, integral battery charger and a universal mounting assembly which is mountable in various configurations of a mobile vehicle, as provided by the present invention. 
       SUMMARY OF THE INVENTION 
       [0007]    The present invention provides a lighting apparatus usable with a mobile vehicle such as a bicycle. In one embodiment, the lighting apparatus includes a first housing, which includes a power source such as rechargeable batteries and a switch mechanism. A second housing is also included which is comprised of light emitting elements such as LEDs. The advantages of LEDs are their smaller size and weight, increased power efficiency, durability, longer life and instant on-off capability. The limitation is that the LEDs provide stationary beams and the cyclist could not easily manipulate the emitting angle of the resultant beam. However, the housings in the present invention are connected by a pivoting mechanism, which allows relative movement between the two housings and permits electrical communication between the light emitting diodes and the batteries. The pivoting mechanism allows the lighting apparatus to provide illumination at different emission angles. The switch mechanism further allows for multiple configurations of the LEDs. The LEDs may be selected to all turn on; all turn off, turn on in a predesignated configuration or turn on in a sequential or nonsequential flashing mode. 
         [0008]    The first housing also includes an integral charging port in order to recharge the batteries. The USB charger is integrated into the unit, and therefore obviates the need to externally couple the charger with the light assembly in order to charge the batteries. 
         [0009]    According to one aspect of the present invention, the lighting apparatus is adapted to a universal mounting assembly. The mounting assembly may be interchangeably attached and detached on different bicycles or on different mounting positions on a particular bike. In the prior art, one disadvantage was that each mount was specific to one specific diameter of handlebar due to the fastener assembly. The problem was that the mount was not adaptable to be used in different configurations: on the top or bottom of the handlebars or on the stem. The mounting assembly of the present invention comprises of a polymeric fastener, such as a TPE or rubber strap for example. In one embodiment, various sizes of straps are provided in order to properly fit various sizes of bicycle stems and handlebars. Alternatively, the fastener can be a universal strap with cutouts in preconfigured locations to allow the mounting assembly to be sized to fit various configurations of a mobile vehicle. In the prior art, the fasteners were often cumbersome to use and required additional accessories like screwdrivers to affix the fastener to the bike. The mounting assembly of the present invention requires no additional tools and improves the ease of attaching and detatching the mounting assembly from a mobile vehicle.
