Title: Safety light

Description:
BACKGROUND 
     The present disclosure relates to a safety light. 
     Individuals are frequently in situations in which a light may facilitate the individual&#39;s safety. For example, safety workers (e.g., law enforcement officers, firefighters, medical personnel, military personnel, and security personnel) walking on the side of a road may carry a light to warn oncoming traffic of their presence. Workers in other industries, such as construction, transportation, power, airports, crossing guards, and towing are also known to carry and wear lights and/or reflective gear to make themselves more visible in the dark. Additionally, individuals engaged in outdoor activities, such as hunting, fishing, boating, camping, rock climbing, and hiking are known to carry and wear lights and/or reflective gear to make themselves more visible. 
     However, the need to carry a light, such as a flashlight or a lantern, is a hindrance because it requires use of an individual&#39;s hand. Conventional wearable lights, such as head lamps, free up the individual&#39;s hand, but are limited in the direction it can project light. Namely, head lamps only project light in front of the user. However, a need exists for a light that can project light in multiple directions at one time. 
     Conventional wearable lights are also bulky due to replaceable batteries and a light source directed out towards the front lens of the wearable light. Bulky lights tend to cause discomfort for a user because of their weight and high likelihood of becoming displaced on a user. 
     The art recognizes a need for a multi-directional safety light that is portable and small in size, and has a low weight. 
     The art further recognizes the need for a multi-directional safety light that is wearable and small in size, and has a low weight.

     Nonlimiting examples of suitable control buttons  42  include depression buttons, depression switches, toggle switches, touch switches, wireless switches, and combinations thereof. In an embodiment, each control button  42  is a depression button. 
     In an embodiment, the PCBA  24  is programmed to energize the plurality of light elements  36  and/or the beacon light element  40  following depression of a control button  42 . In an embodiment, the PCBA  24  is programmed to stop energy to the plurality of light elements  36  and/or the beacon light element  40  following another depression of the control button  42 , such that a first depression energizes the light element ( 36  and/or  40 ) and a second depression stops energy to the light element ( 36  and/or  40 ). When energy is stopped, the light element ( 36  and/or  40 ) does not emit light, i.e., the light element is “off” When a light element ( 36  and/or  40 ) is energized, it emits a light, i.e., the element is “on.” 
     In an embodiment, the control button  42  is a touch switch. A “touch switch” enables a user to tap the safety light  10 , such as on the top housing&#39;s top surface  16 , to activate or de-activate a sensor, thereby energizing or stopping energy to (respectively) the plurality of light elements  36  and/or the beacon light element  40 . 
     In an embodiment, the PCBA  24  is programmed to energize the plurality of light elements  36  following depression of a first control button  42   a .

In an embodiment, the emergency button  44  is centrally positioned in the top housing  12 , as shown in  FIG. 1 . 
     In an embodiment, the PCBA  24  includes a control button  42  that is a power-saver button  46 , as shown in  FIG. 16 . A “power-saver button” energizes only a portion of the light elements ( 36  and/or  40 ) to energize. In an embodiment, the power-saver button energizes from 10%, or 20%, or 30%, or 40% to 50%, or 60%, or 70%, or 80% of the light elements ( 36  and  40 ) of the safety light  10 . 
     The control buttons ( 42 ,  44 ,  46 ) are formed from one or more flexible materials. A nonlimiting example of a suitable flexible material is rubber. 
     In an embodiment, the control buttons ( 42 ,  44 ,  46 ) are formed from a button pad  48 , as shown in  FIGS. 16 and 17 .

In an embodiment, the top housing  12  includes a plurality of button openings  54 , wherein each button opening  54  is aligned with a control button ( 42 ,  44 ,  46 ) of the button pad  48 . The number of control buttons ( 42 ,  44 ,  46 ) on the button pad  48  is the same number of button openings  54  in the top housing  12 . 
     In an embodiment, the button pad  48  includes a beacon opening  58 , as shown in  FIGS. 16 and 17 . A “beacon opening” is a void in the button pad  48  sized to receive the beacon light element  40  such that the beacon light element  40  may extend through the button pad  48 . 
     In an embodiment, the bottom portion  48   b  of the button pad  48  serves as a rubberized gasket that forms a watertight or semi-watertight seal between the lens  64  and the top housing  12 . 
     The control button  42  may comprise two or more embodiments disclosed herein. 
     The button pad  48  may comprise two or more embodiments disclosed herein. 
     F. Beacon Light Lens 
     In an embodiment, the safety light  10  includes a beacon light lens  60 , as shown in  FIGS. 1, 18-20, and 70 . The beacon light lens  60  is coupled to the beacon light element  40 . 
     The beacon light lens  60  is formed from one or more rigid materials through which light may pass through. Nonlimiting examples of suitable rigid materials include high impact polymers, thermoplastic polymers, thermoset polymers, composites, glass, ceramics, cellulose, acrylics, combinations thereof, and/or the like. In an embodiment, the beacon light lens  60  is formed from glass, polymethyl methacrylate, a polycarbonate resin, a polystyrene resin, a styrene-acrylonitrile resin, cellulose acetate, polypropylene, nylon, polychlorotrifluoroethylene, ethylene-tetrafluoroethylene copolymer, polyvinylidene chloride, fluorinated ethylene/propylene copolymer, polyethylene terephthalate, silica class, or combinations thereof. In an embodiment, the beacon light lens  60  is formed from a transparent material or a translucent material. A “transparent” material allows all light, or 100% of light, to pass through the material, A “translucent” material allows from greater than 0% to less than 100% of light to pass through the material. 
     The beacon light lens  60  has a cross-sectional shape. The cross-sectional shape may be any cross-sectional shape disclosed herein.  FIG. 19  depicts a beacon light lens  60  with a circular cross-sectional shape. 
     In an embodiment, the beacon light lens  60  is coupled to the beacon light element  40  and the button pad  48 . In a further embodiment, the beacon light lens  60  is coupled to the beacon light element  40  and the top surface  50  of the button pad  48 . 
     The beacon light lens  60  is aligned with the beacon light element  40  such that light emitted from the beacon light element  40  passes through the beacon light lens  60 . 
     In an embodiment, the top housing  12  has a beacon light lens opening  62 , as shown in  FIG. 2 . A “beacon light lens opening” is a void in the wall  14  of the top housing  12  sized to receive the beacon light lens  60  such that at least a portion of the beacon light lens  60  may extend through the top housing  12 . 
     In an embodiment, the beacon light lens  60  has a top portion  60   a  and a bottom portion  60   b , as shown in  FIG. 18 . The top portion  60   a  has a diameter that is less than (&lt;) the diameter of the bottom portion  60   b.    
     In an embodiment, the beacon light lens  60  has a reflective surface  61  in the bottom portion  60   b , as shown in  FIG. 18 . A “reflective surface” is a plane capable of reflecting light. In an embodiment, the plane is coated with a reflective material, such as a metal (e.g., nickel, chromium, aluminum, gold, silver, and combinations thereof) or a polymeric material to form a reflective surface. In an embodiment, the reflective material is vacuum-deposited on the plane to form a reflective surface. In an embodiment, the reflective surface  61  has a conical shape, as shown in  FIG. 18 . Light emitted from the beacon light element  40  reflects off of the reflective surface  61  and projects through the top portion  60   a  of the beacon light lens  60 . 
     In an embodiment, the top housing  12  has a beacon light lens opening  62  sized to receive the top portion  60   a  of the beacon light lens  60 , but not the bottom portion  60   b  of the beacon light lens  60 . Consequently, the bottom portion  60   b  of the beacon light lens  60  is contained within the safety light  10  below the bottom surface  18  of the top housing  12 . In an embodiment, the bottom portion  60   b  of the beacon light lens  60  is contained within the safety light  10  below the bottom surface  18  of the top housing  12  and above the top surface  50  of the button pad  48 . In other words, the bottom portion  60   b  of the beacon light lens  60  is positioned between the button pad  48  and the top housing  12 , and the top portion  60   a  of the beacon light lens  60  extends through the wall  14  of the top housing  12 . 
     The beacon light lens  60  may or may not protrude past the top surface  16  of the top housing  12 . In an embodiment, the beacon light lens  60  protrudes past the top surface  16  of the top housing  12 , as shown in  FIGS. 1, 60, and 68 . 
     The safety light  10  includes the same number of beacon light elements  40  and beacon light lenses  60 . In an embodiment, the safety light  10  includes from 1 to 2, or 3, or 4 beacon light lenses  60 . In an embodiment, the safety light  10  includes one and only one beacon light lens  60 . 
     The beacon light lens  60  may comprise two or more embodiments disclosed herein. 
     G. Lens 
     The safety light  10  includes a lens  64  coupled to the bottom surface  28  of the PCBA  24  and the plurality of light elements  36 , the lens  64  having an angled reflective surface  66  and a plurality of side surfaces  68 , as shown in  FIGS. 1 and 21-29 . 
     The lens  64  may be formed from any lens material disclosed herein. In an embodiment, the lens  64  is formed from a transparent material or a translucent material. 
     In an embodiment, the lens  64  has two opposing surfaces, including a top surface  70  and a bottom surface  72 , as shown in  FIGS. 21 and 22 . The top surface  70  of the lens  64  is oriented parallel to the bottom surface  72  of the lens  64 . The term “parallel,” as used herein, indicates the top surface  70  extends in the same direction, or substantially the same direction, as the bottom surface  72  of the lens  64 .  FIG. 29  depicts a top surface  70  and a bottom surface  72  that are parallel to one another. 
     In an embodiment, the lens  64  has a bottom surface  72  that is a reflective surface. A “reflective surface” is a plane capable of reflecting light. In an embodiment, the plane is coated with a reflective material, such as a metal (e.g., nickel, chromium, aluminum, gold, silver, and combinations thereof) or a polymeric material to form a reflective surface. In an embodiment, the reflective material is vacuum-deposited on the plane to form a reflective surface. 
     The lens  64  includes an angled reflective surface  66 . An “angled reflective surface” is a plane extending at an angle other than 90° from the top surface  70  of the lens  64 , the bottom surface  72  of the lens, or combinations thereof, the plane capable of reflecting light emitted from the plurality of light elements  36 . The angled reflective surface  66  may be flat or curved. In an embodiment, the angled reflective surface  66  is flat, or is not curved.  FIGS. 21-29  depict a lens  64  with a flat angled reflective surface  66 . 
     In an embodiment, the angle, X, between the bottom surface  72  and the angled reflective surface  66  is from 110°, or 115°, or 120°, or 125° to 130°, or 135°, or 140°, or 145°, or 150°, as shown in  FIG. 29 . In an embodiment, the angle, X, between the bottom surface  72  and the angled reflective surface  66  is 135°. 
     In an embodiment, the lens  64  includes from 1 to 2, or 3, or 4, or 5, or 6, or 7, or 8, or 9, or 10, or 12, or 14, or 16, or 18, or 20, or 22, or 24, or 26, or 28, or 30, or 40 angled reflective surfaces  66 . For purposes of this disclosure, each angled reflective surface  66  having the same angle, X, of from 110°, or 115°, or 120°, or 125° to 130°, or 135°, or 140°, or 145°, or 150°, between the bottom surface  72  of the lens  64  and the angled reflective surface  66  shall constitute a “first angled reflective surface”  66   a , as shown in  FIGS. 21-29 . However, it is understood that the first angled reflective surface  66   a  depicted in  FIGS. 21-29  includes 18 individual flat angled reflective surfaces  66 , as shown in  FIG. 26 . 
     In an embodiment, the angle, Y, between the top surface  70  and the angled reflective surface  66  is from 110°, or 115°, or 120°, or 125° to 130°, or 135°, or 140°, or 145°, or 150°, as shown in  FIG. 29 . In an embodiment, the angle, Y, between the top surface  70  and the angled reflective surface  66  is 135°. 
     In an embodiment, the lens  64  includes the first angled reflective surface  66   a  and a second angled reflective surface  66   b , as shown in  FIGS. 21-29 . For purposes of this disclosure, each angled reflective surface  66  having the same angle, Y, of from 110°, or 115°, or 120°, or 125° to 130°, or 135°, or 140°, or 145°, or 150°, between the top surface  70  of the lens  64  and the angled reflective surface  66  shall constitute a “second angled reflective surface”  66   b , as shown in  FIGS. 21-29 . However, it is understood that the second angled reflective surface  66   b  depicted in  FIGS. 21-29  includes 14 individual flat angled reflective surfaces, as shown in  FIGS. 21 and 25 . 
     In an embodiment, the lens  64  includes the first angled reflective surface  66   a  and the second angled reflective surface  66   b , and the angle, Z, between the first angled reflective surface  66   a  and the second angled reflective surface  66   b  is from 80°, or 85° to 90°, or 95°, or 100°, as shown in  FIG. 29 . In an embodiment, the lens  64  includes the first angled reflective surface  66   a  and the second angled reflective surface  66   b , and the angle, Z, between the first angled reflective surface  66   a  and the second angled reflective surface  66   b  is 90°. 
     The first angled reflective surface  66   a  and the second angled reflective surface  66   b  may or may not be continuous around the perimeter  74  of the lens  64 .  FIGS. 21-29  depict a first angled reflective surface  66   a  and a second angled reflective surface  66   b  that are not continuous around the perimeter  74  of the lens  64 , rather, they are discontinuous. 
     In an embodiment, the lens  64  includes a first angled reflective surface  66   a  and the angle, X, between the bottom surface  72  and the first angled reflective surface  66   a  is 135°. In another embodiment, the lens  64  includes a second angled reflective surface  66   b  and the angle, Y, between the top surface  70  and the second angled reflective surface  66   b  is 135°. In a further embodiment, the angle, Z, between the first angled reflective surface  66   a  and the second angled reflective surface  66   b  is 90°. 
     The lens  64  has a plurality of side surfaces  68 . In an embodiment, the lens  64  includes from 4 to 5, or 6, or 7, or 8 side surfaces  68 . In an embodiment, the lens  64  includes four side surfaces  68 . In an embodiment, the lens  64  includes a front side surface  68   a , a rear side surface  68   b , a left side surface  68   c , and a right side surface  68   d , as shown in  FIGS. 21-24, 27 and 28 . Each side surface  68  extends perpendicular to the top surface  70  and the bottom surface  72  of the lens  64 , as shown in  FIG. 29 . A side surface  68  that extends “perpendicular” to the top surface  70  and the bottom surface  72  of the lens  64  is at a 90° angle with the top surface  70  and the bottom surface  72  of the lens  64 . Each side surface  68  may be flat or curved.  FIG. 29  depicts a lens  64  with flat side surfaces  68 . 
     The side surfaces  68  extend in a continuous manner around the perimeter  74  of the lens  64 . 
     The side surfaces  68  are not reflective. In other words, light is not reflected by the side surfaces  68  of the lens  64 , but rather transmits, or projects, through the side surfaces  68 . 
     In an embodiment, the plurality of light elements  36  emit a light directed away from the bottom surface  28  of the PCBA  24  and the light reflects off of the first angled reflective surface  66   a  of the lens  64  and projects through the plurality of side surfaces  68  of the lens  64 . It is understood that the angle of incidence (i.e., the angle a light hits a reflective surface) is equal to the angle of reflection (i.e., the angle at which the light reflects off of the reflective surface). Thus, the present safety light  10  may advantageously direct its light elements  36  downward, such as at a 90° angle with the top surface  70  of the lens  64 , and still project the light outward through the plurality of side surfaces  68  of the lens  64  in a direction that is parallel, or substantially parallel, to the top surface  70  of the lens  64 . This configuration allows for light elements  36  to be located above the lens  64 , rather than behind (i.e., parallel to) the lens, allowing for a safety light  10  with a smaller length and width compared to conventional safety lights. 
     In an embodiment, the lens  64  includes a plurality of light posts  76  coupled to the top surface  70  of the lens  64 , as shown in  FIGS. 21, 27 and 28 . The lens  64  and the light posts  76  may have an integral design or a composite design. A lens  64  with light posts  76  having an “integral design” is formed from one piece of rigid material, such as a molded piece. A lens  64  with light posts  76  having a “composite design” is formed from more than one distinct piece (or part), which upon assembly are combined. Each light post  76  is coupled to a light element  36 . Thus, the safety light  10  includes the same number of light elements  36  and light posts  76 . The light posts  76  advantageously reduce the separation between the lens  64  and the plurality of light elements  36 , and thus reduce the amount of air present between the lens  64  and the plurality of light elements  36 . Reduced air between the lens  64  and the plurality of light elements  36  reduces the amount of light dissipation and attenuation that occurs in air, resulting in more light entering the lens  64 . 
     Each light post  76  has a shape. Nonlimiting examples of suitable shapes include square prism, rectangular prism, cylinder, frustum, pentagonal prism, trapezium prism, and combinations thereof.  FIG. 21  depicts light posts  76  with a rectangular prism shape. 
     The lens  64  may comprise two or more embodiments disclosed herein. 
     In an embodiment, the lens  364  includes a plurality of spacing posts  377  coupled to the top surface  370  of the lens  364 , as shown in  FIG. 80 . The lens  364  and the spacing posts  377  may have an integral design or a composite design. A lens  364  with spacing posts  377  having an “integral design” is formed from one piece of rigid material, such as a molded piece. A lens  364  with spacing posts  377  having a “composite design” is formed from more than one distinct piece (or part), which upon assembly are combined. The spacing posts  377  are positioned between the light posts  376 , as shown in  FIG. 80 . Each spacing post  377  has a height, H S , that is the distance between the lens top surface  370  and the spacing post top surface  379 . Each light post  376  has a height, H P , that is the distance between the lens top surface  370  and the light post top surface  379 . Each spacing post  377  has a height, H S , that is that is greater than the height, H P , of each light post  376 , as shown in  FIG. 80 . The PCBA bottom surface is in contact with the top surface  379  of each spacing post  377 . When the PCBA bottom surface is in contact with the top surface  379  of each spacing post  377 , a gap (i.e., a void) is present between the top surface  375  of each light post  376  and each light element. In other words, the light elements are not in direct contact with the lens  374 , and further the light posts  376 . The gap protects the light elements from potential damage that may be caused by direct contact between the light elements and the lens  364 . As used herein, “direct contact” refers to a configuration whereby the light element is located immediately adjacent to the lens  364 , the light element touches the lens  364 , and no intervening structures, or substantial voids, or voids, are present between the light element and the lens  364 .
