Abstract:
A light system is provided that can be removably coupled to a layer of material, such as clothing, to provide hands-free illumination for tasks and activities (e.g., while walking, running, reading, writing) at low level light conditions. The light system includes a light module with one or more light sources, a power source and one or more magnetic elements or magnetically responsive modules. The light system also includes a backing plate removably coupleable to the light module so that the layer of material is interposed between the light module and the backing plate. The backing plate has one or more magnetic elements or magnetically responsive modules. When removably coupled to said layer of material, the light module and backing plate remain substantially in place even when the layer of material is under motion.

INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
     Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57. 
     BACKGROUND 
     Field 
     This invention relates to the field of portable lighting systems. More specifically, the invention comprises a lighting system that provides hands-free illumination for activities in low level light conditions, e.g. at night. 
     Description of the Related Art 
     There are many known devices that attach to a person that provide illumination for activities in low level light conditions. Generally, they fall into 2 categories: 
     A) Lighting systems that allow the user to safely conduct their activities by illuminating their field of vision. These systems are usually lights that the person is holding in their hands or attach to the person&#39;s body or garments via straps and/or clips. 
     B) Devices that alert another person(s) approaching the first person of their presence. This is done usually through flashing and/or constant illumination of a light source, most commonly of a RED colored light for maximum distance visibility with the purpose of avoiding being struck by a vehicle. 
     Of the lighting systems in Category A that provide hands-free illumination, the most popular systems attach to the user&#39;s head via straps, or attach to a bill of a hat. Both of these options are less than desirable as one may not want to have to wear anything on their head when pursuing certain activities. They also require the lighting system to be mounted close to the person&#39;s eyes, resulting in the adverse effect of blinding the user. Additionally, these systems move with the head, so when a user looks up at an approaching vehicle, there&#39;s a potential of temporarily blinding the oncoming driver. 
     SUMMARY 
     An LED light system that is removably coupleable to a layer of material (e.g., running apparel, hiking apparel, tents, bags) or other components to provide hands-free illumination (e.g., while walking, running, reading) at low level light conditions. 
     The system is comprised of two separate housings, an LED light module and a backing plate. The backing plate contains a magnetic element and removably couples to a magnetic element in the LED light assembly, whereby the material layer can be sandwiched between the backing plate and the light module, thus mounting the LED light system on any position where a layer of material is present. 
     This allows for hands-free illumination of a desired area which is the focus of an activity or a task. 
     By freely being able to place the light on different areas of the user&#39;s garment, the illuminated area can be changed seamlessly. The advantage of this configuration is that the person&#39;s hands are free to pursue activities, and that it is not necessary to use straps or clips that limit the available positions for mounting, or mandating the use of additional garments and accessories (e.g. hats, glasses, helmets) that may not be desired for the chosen activity. 
     The light emitted by the LED light system is directed downwards at an angle, thus avoiding shining in the user&#39;s or approaching persons&#39; eyes. 
     In accordance with one embodiment, a light system is provided that is removably coupleable to a layer of material to provide hands-free illumination at low level light conditions. The light system comprises a light module comprising one or more light sources, a power source and one or more magnetic elements or magnetically responsive modules. The light system also comprises a backing plate removably coupleable to the light module so that the layer of material is interposed between the light module and the backing plate, the backing plate comprising one or more magnetic elements or magnetically responsive modules. When removably coupled to said layer of material, the light module and backing plate remain substantially in place even when the layer of material is under motion. 
     In accordance with another embodiment, a light system is provided that is removably coupleable to a layer of material to provide hands-free illumination at low level light conditions. The light system comprises a light module comprising one or more light sources, a power source and one or more magnetic elements or magnetically responsive modules. The light system also comprises a backing plate removably coupleable to the light module so that the layer of material is interposed between the light module and the backing plate, the backing plate comprising one or more magnetic elements or magnetically responsive modules. The one or more light sources are operable to provide one or both of: a lower intensity, but wider dispersed ambient light to illuminate the peripheral vision and to help alert potential approaching persons and vehicles by illuminating a wider range of the environment; and a higher intensity, more focused task light helping to illuminate an area from the person&#39;s feet to about 6-10 feet ahead, if the light is mounted centered on the person&#39;s chest. When removably coupled to said layer of material, the light module and backing plate remain substantially in place even when the layer of material is under motion.

In another embodiment, the Power Switch  211  can be triggered by a photo detector. In another embodiment, the Power Switch  211  can be activated by a motion sensor. 
     In one embodiment, the light module  200  can contain a mask layer  230  of a light fast material, such as a polymer with one or more apertures  231  to allow for the light to penetrate through the mask layer in at least one specified location. Such layer can, in one embodiment, be spatially affixed to the optic  220 . 
     In one embodiment, the PCB  240  can have one or more light sources, such an 5050 SMT LED; it can have a charging interface such as a Micro USB module  242 . 
     In one embodiment, the light module  200  can also contain a power source  250 , such as a rechargeable Lithium Polymer Battery. This power source  250  can be electrically connected to the PCB  240  and can be recharged by connecting an external cable to the Micro USB module  242 . 
     In one embodiment, the PCB  240  can also contain indicator LEDs that indicate status of the power source while charging and/or when the power source is fully charged. 
     In another embodiment, the light module  200  can contain a wireless induction charging module, and or a charging module with an interface protruding through the housing of the light module. 
     In another embodiment, the light module  200  can also contain a data transfer module, and/or a Global Positioning System (GPS) module, and/or a motion sensing module, and/or an altitude sensing module, and/or a module to emit a distress signal (e.g., an audible alarm, a personal locator beacon signal). 
     In one embodiment, the light module can contain a magnetically responsive element  260 , such as a Neodymium Disk with a pull force of at least about 4 lbs., in another embodiment a pull force of at least about 6 lbs., in still another embodiment a pull force of at least about 8 lbs (i.e., a pull force of 8 lbs.), and in another embodiment a pull force of at least about 10 lbs, and still in another embodiment a pull force of at least about 12 lbs. 
     In one embodiment, the front housing  210  and back housing  270  can contain features such as reinforcement walls and bosses to help locate and affix internal components and to help in attaching the front housing  210  to the back housing  270 . 
     In one embodiment, the light module  200  can be assembled in a fashion where it provides a water resistant module. This could be achieved with including an gasket feature at the seams where the housing parts come together. In another embodiment, forming the front housing  210  and back housing  270  with two or more materials of varying durometer. In another embodiment, the internal components can be treated with a coating to provide water resistance. 
       FIGS. 4A-5  show one embodiment of the back plate  300 . The back plate  300  can contain at least one magnetically responsive element  320 , such as a N52 Neodymium Disk with a pull force of at least about 4 lbs., at least about 6 lbs., or at least about 8 lbs; a front housing  310 ; a back housing  330 . In another embodiment, one or both housing modules  310  and  330  can be omitted. 
     The front housing  310  and back housing  330  can contain features such as reinforcement walls and bosses to help locate and affix internal components and to help in attaching the front housing  310  to the back housing  330 . In one embodiment, the magnetically responsive element  320  can be fully enclosed. In another embodiment, the magnetic element can protrude through an orifice in the front housing  310  and/or back housing  330 . 
       FIGS. 6A-6B  show one embodiment of the light module  200  and the backing plate  300 . They are held together by magnetic force but can be pulled apart with sufficient force. By spatially aligning the magnetically responsive modules, the light module  200  and back plate  300  can align in a similar fashion every time they are coupled. 
       FIGS. 7A-7E  show schematic views of one embodiment of the LED light system. 
       FIGS. 8A-8B  show schematic views of one embodiment of the light module  200  and backing plate  300 .  FIG. 8A  shows how, by aligning the light module  200  and back plate  300 , a layer of material (e.g., running shirt, tent, bag) can be sandwiched. The magnetically responsive modules engage the pull forces. The pull force can be strong enough to hold the light system in place, even when physically moving the material layer (e.g., while walking, running, hiking, jumping). When grabbing the light module  200  and/or back plate  300  the light system can be moved and repositioned on the material layer without disengaging the pull force.

       FIG. 9A  shows one embodiment, where the light emitted is projected downward at an angle of between about 15-45 degrees. However, the emitted light can be projected at other suitable angles. There can be two light types emitted when the LED light system is powered on: A higher intensity light beam, task light  280 ; and a lower intensity but wider spread, ambient light  281 . 
     In one embodiment, pressing repeatedly on the power button will cycle through the following modes:
         1. Both task light  280  and ambient light  281     2. Only task light  280  is on   3. Task light  280  is blinking perceivably to the human eye   4. Unit is off.       

       FIG. 9A  also shows how the light system can be used in a physical activity such as running. 
       FIG. 9B  shows how the projection angle of the light can also work for illumination of detailed tasks closer to the person&#39;s body.
