BACKGROUND
The present disclosure relates to a safety light.
Individuals are frequently in situations in which a light may facilitate the individual'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's hand. Conventional wearable lights, such as head lamps, free up the individual'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.

Correspondingly, the port 34 can be configured as a communication port. The communication port 34 can be configured to allow an external device (e.g., a computer, a portable electronic device, a data storage device, etc., not shown) to communicate with the PCBA 24, e.g., to control a lighting element 36, 40 or another function of the safety light 10, or to transfer data between the PCBA 24 and the external device). Alternatively or additionally, the power coupling 35 can also be configured to communicate with the PCBA 24 to allow for wireless communication with the PCBA 24 (e.g., to wireless transmit data or other types of signals between the safety light 10 and an external device) or to control of one or functions of the safety light 10 (e.g., to control a lighting element 36, 40, or another function).
In an embodiment, the PCBA 24 is configured to provide Global Positioning System (GPS) capability to the safety light 10.
In an embodiment, the PCBA 24 is configured to generate, collect, store, and/or transfer data. Nonlimiting examples of data that the PCBA 24 may be configured to generate, collect, store, and/or transfer include safety light 10 usage data (e.g., duration of battery life; duration of time that a light, such as the plurality of light elements 36 and/or the beacon light element 40, is emitting light; location information, such as locations derived from GPS; and combinations thereof); testing analytics of the safety light 10 (e.g., detection of faulty components, detection of light outages, detection of software errors, and combinations thereof); biometric data (e.g., heartrate, temperature, facial recognition, and/or facial expression information on a user wearing the safety light 10 and/or an individual in proximity to the safety light 10); camera images; video; sound recordings; and combinations thereof.
In an embodiment, the PCBA 24 is configured to wirelessly connect, including sending and receiving wireless communications, with a wireless device, such as a cell phone, a remote (e.g. a central control system or main server), signal repeaters, or another safety light, or other external devices. In that regard, the PCBA 24 can include at least one communication module 25 (see FIG. 83) that can be configured to send and receive wireless communications via one or more wireless connections. Nonlimiting examples of suitable wireless connections include GPS, Bluetooth, radio frequency (RF), and Wireless Fidelity (WiFi).
In an embodiment, the PCBA 24 is configured to energize the plurality of light elements 36 and/or the beacon light element 40 via (e.g., in accordance with) a wireless communication from a wireless device. As one particular non-limiting example, the PCBA 24 can pair with an external device, such as a cell phone. tablet, or other mobile device, to allow a user to control the safety light 10 (e.g., to energize or deenergize one or more lighting elements 36, 40) from the external device. That is, an external device can run an application that can allow a user to interact with the device, for example, by displaying a virtual device to the user, which may mimic a control button layout, of the connected safety light 10, as described in greater detail below. Additionally, a PCBA 24 can be configure to pair with an external device to allow automatic control of the safety light 10 using one or more sensors of the external device. For example, a PCBA 24 may be configured to energize one or more lighting elements in response to a signal from an accelerometer or GPS module of the external device (e.g., a signal indicative of a braking or slowing event, or upon entering or exiting a geofenced area). Similarly, a PCBA 24 may be configured to communicate with an external device (e.g., a vehicle) to determine a proximity to the external device, and to control one or more lighting elements 36, 40 accordingly, for example, to energize a lighting element upon exiting a vehicle and to deenergize a lighting element when entering a vehicle.
In an embodiment, software, firmware, usage data, testing analytics of the safety light, biometric data, camera images, video, sound recordings, and combinations thereof may be wirelessly transferred as a wireless communication. As one particular non-limiting example, a PCBA 24 of a safety light 10 can be configured to communicate geolocation data of the safety light 10 to a central server or another external device, which can allow a user to see location data of the safety light 10, as well as any other safety lights that are in communication with the central server (e.g., each safety light in a network of safety lights). Relatedly, where a safety light 10 is in communication with a central server, a user can upload, for example, (custom) firmware or software) to the safety light 10, as a well as any other safety lights that are connected to the server, either individually or simultaneously.
The PCBA 24 may comprise two or more embodiments disclosed herein.

In an embodiment, the beacon light element 40 coupled to the top surface 26 of the PCBA 24 emits a light directed away from, or in opposite direction from, the bottom housing 94. In an embodiment, the beacon light element 40 coupled to the top surface 26 of the PCBA 24 emits a light at an angle of from 75°, or 80°, or 85° to 90°, or 95°, or 100°, or 105° relative to the top surface 26 of the PCBA 24. In another embodiment, the beacon light element 40 coupled to the top surface 26 of the PCBA 24 emits a light at an angle of 90° relative to the top surface 26 of the PCBA 24.
In an embodiment, the beacon light element 40 emits a light in the opposite direction from the light emitted from the plurality of light elements 36.
The beacon light element 40 is electrically connected to the PCBA 24.
In an embodiment, the safety light 10 includes from 1 to 2, or 3, or 4 beacon light elements 40. In an embodiment, the safety light 10 includes one and only one beacon light element 40.
The beacon light element 40 may comprise two or more embodiments disclosed herein.
E. Control Button
The safety light 10 includes at least one control button 42, as shown in FIGS. 1, 16 and 17.
In an embodiment, the safety light 10 includes a plurality of control buttons 42. In an embodiment, the safety light 10 includes from 1, or 2 to 3, or 4, or 5, or 6 control buttons 42.
Each control button 42 is connected to the PCBA 24 via a mechanical connection, an electrical connection, or a combination thereof.
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'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. For example, a touch switch can be configured as a capacitive switch, a resistive switch, a piezo switch, etc.
In an embodiment, the PCBA 24 is programmed to energize the plurality of light elements 36 following depression of a first control button 42a. In another embodiment, the PCBA 24 is programmed to energize the beacon light element 40 following depression of a second control button 42b. 
In an embodiment, the PCBA 24 is programmed to energize a first group of the plurality of light elements 36a following depression of a first control button 42a and a second group of the plurality of light elements 36b following depression of a second control button 42b. In an embodiment, the first group of the plurality of light elements 36a are those light elements 36 near the front surface 30a of the PCBA 24 and the second group of the plurality of light elements 36b are those light elements 36 near the rear surface 30b of the PCBA 24, as shown in FIG. 13. In another embodiment, the PCBA 24 is programmed to energize the beacon light element 40 following depression of a third control button 42c. Alternatively or additionally, the PCBA 24 is programmed to energize the flashlight light element 41 (see FIG. 83) following the depression of the third control button 32c. The flashlight light element 41 can be configured to emit a light out of the lens 64 or a separate flashlight lens (not shown). Relatedly, the lens 64 can be shaped differently around the flashlight element 41 to provide a specific light output or beam pattern. For example, the lens 64 can be configured to provide a beam of light from the flashlight light element 41, while providing a diffuse light from the first group of the plurality of light elements 36a. 
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 to cause the light element (36 and/or 40) to emit a certain type of light, a certain color of light, or combinations thereof.
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 to cause the light element (36 and/or 40) to emit light in a pattern, such as in a strobe pattern, a timed flash pattern, a running pattern, an alternating color pattern, or combinations thereof.
In an embodiment, the PCBA 24 is programmed to energize the plurality of light elements 36 and the beacon light element 40 following depression of a single control button 42.
In an embodiment, the PCBA 24 includes a control button 42 that is an emergency button 44, as shown in FIG. 1. An “emergency button” is capable of energizing all light elements (36 and/or 40) following a depression and stopping all energy to all light elements (36 and/or 40) following a second depression. 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.
In an embodiment, a control button 42, in conjunction with a PCBA 24, can be configured to provide a different function or control a safety light in a specific way depending on how the button 42 is pressed (e.g., depending on sequence of button presses or a duration of a button press). For example, when at least one lighting element 36, 40 is powered, a “short” press (e.g., a press duration of less than one second) of the power saver button 46 can (sequentially) energize the at least one lighting element 36, 40 from 10%, or 20%, or 30%, or 40% to 50%, or 60%, or 70%, or 80%, or 90%, or 100%. Alternatively, if no lighting elements are energized a “short” press of the power saver button 46 may do nothing, while a “long” press (e.g., a press duration of greater than or equal to one second) may cause one or more lighting elements 36, 40 to become energized, for example to flash in an “S.O.S.” pattern.
In an embodiment, the PCBA 24 may also include one or more buttons 42 that are configured to control one or more functions that may or may not be related to energizing one of the lighting elements 36, 40. For example, as shown in FIG. 84, an embodiment includes a control button 42 that is configured as a multi-function control button 47 that can be configured to carry out one or more functions of the safety light 10. As one particular nonlimiting example, a “short” press of the button 47 can energize or deenergize the beacon light element 40, while a “long” press can control the PCBA 24 to control one or more communication modules 25 (e.g., to enter a Bluetooth pairing mode, or to send another type of wireless communication, or wirelessly transmit data).
Relatedly, in an embodiment, buttons 42 can be symmetrically arranged (e.g., mirrored about plane M, see FIG. 84) with one or more types of symmetry, or non-symmetrically arranged (see FIG. 16).
The control buttons (e.g., 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 button pad 48 has an integral design such that the control buttons (42, 44, 46) are formed from one piece of flexible material. The button pad 48 has two opposing surfaces, including a top surface 50 and a bottom surface 52. As shown in FIG. 16, the control buttons (42, 44, 46) protrude from the top surface 50 of the button pad 48.
The button pad 48 has a cross-sectional shape. The cross-sectional shape may be any cross-sectional shape disclosed herein. The cross-sectional shape of the button pad 48 is the same cross-sectional shape as the top housing 12. FIGS. 16 and 17 depict a button pad 48 with a rectangle cross-sectional shape.
In an embodiment, the button pad 48 includes a plurality of threaded openings 56, as shown in FIGS. 16 and 17. A “threaded opening” is a void in the button pad 48 sized to receive a threaded fastener 114, such as a screw. The threaded opening 56 allows the threaded fastener 114 to extend through the button pad 48. In an embodiment, the threaded openings 56 of the button pad 48 align with the threaded openings 38 of the PCBA 24, which align with the threaded connector 22 of the top housing 12 such that a threaded fastener 114 may extend through the PCBA 24 and the button pad 48 and connect to the top housing 12. In an embodiment, the button pad 48 includes from 2, or 3 to 4, or 5, or 6 threaded openings 56. In an embodiment, the button pad 48 includes four threaded openings 56.
In an embodiment, the button pad 48 has a top portion 48a and a bottom portion 48b, as shown in FIG. 16. In an embodiment, the top housing 12 is sized to receive the top portion 48a of the button pad 48.
In an embodiment, the top housing 12 includes a plurality of button openings 54, as shown in FIG. 2. A “button opening” is a void in the wall 14 of the top housing 12 such that a control button (42, 44, 46) may extend through the wall 14, as shown in FIGS. 1 and 59. 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 48b 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 methacylate, 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 telephthaleate, 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 60a and a bottom portion 60b, as shown in FIG. 18. The top portion 60a has a diameter that is less than (<) the diameter of the bottom portion 60b. 
In an embodiment, the beacon light lens 60 has a reflective surface 61 in the bottom portion 60b, 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 60a 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 60a of the beacon light lens 60, but not the bottom portion 60b of the beacon light lens 60. Consequently, the bottom portion 60b 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 60b 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 60b of the beacon light lens 60 is positioned between the button pad 48 and the top housing 12, and the top portion 60a 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 is a monolithic lens, but can also be configured differently, for example, as a hollow lens.
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” 66a, as shown in FIGS. 21-29. However, it is understood that the first angled reflective surface 66a 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 66a and a second angled reflective surface 66b, 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” 66b, as shown in FIGS. 21-29. However, it is understood that the second angled reflective surface 66b 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 66a and the second angled reflective surface 66b, and the angle, Z, between the first angled reflective surface 66a and the second angled reflective surface 66b 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 66a and the second angled reflective surface 66b, and the angle, Z, between the first angled reflective surface 66a and the second angled reflective surface 66b is 90°.
The first angled reflective surface 66a and the second angled reflective surface 66b may or may not be continuous around the perimeter 74 of the lens 64. FIGS. 21-29 depict a first angled reflective surface 66a and a second angled reflective surface 66b 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 66a and the angle, X, between the bottom surface 72 and the first angled reflective surface 66a is 135°. In another embodiment, the lens 64 includes a second angled reflective surface 66b and the angle, Y, between the top surface 70 and the second angled reflective surface 66b is 135°. In a further embodiment, the angle, Z, between the first angled reflective surface 66a and the second angled reflective surface 66b 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 that extends generally between the top housing 12 and the bottom housing 94. In an embodiment, the lens 64 includes a front side surface 68a, a rear side surface 68b, a left side surface 68c, and a right side surface 68d, 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 an approximately 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 (e.g., from the top housing 12 and toward the bottom housing 94) and the light reflects off of the first angled reflective surface 66a 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, HS, that is the distance between the lens top surface 370 and the spacing post top surface 379. Each light post 376 has a height, HP, that is the distance between the lens top surface 370 and the light post top surface 379. Each spacing post 377 has a height, HS, that is greater than the height, HP, 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, not in direct contact with 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.
In an embodiment, each light post 376 has a height, HP, that is from 1 mm, or 1.5 mm, or 1.9 mm to 2.0 mm, or 2.5 mm.
In an embodiment, each spacing post 377 has a height, HS, that is from 2.6 mm, or 2.7 mm, or 2.8 mm to 2.9 mm, or 3.0 mm, or 3.2 mm, or 3.5 mm.
In an embodiment, each light post 376 has a height, HP, that is from 1 mm, or 1.5 mm, or 1.9 mm to 2.0 mm, or 2.5 mm; and each spacing post 377 has a height, HS, that is from 2.6 mm, or 2.7 mm, or 2.8 mm to 2.9 mm, or 3.0 mm, or 3.2 mm, or 3.5 mm. In a further embodiment, each light post 376 has a height, HP, that is from 1.9 mm to 2.0 mm; and each spacing post 377 has a height, HS, that is from 2.8 mm to 2.9 mm.
In an embodiment, the lens 364 includes from 2, or 3, or 4 to 5, or 6, or 7, or 8, or 10 spacing posts 377. In a further embodiment, the lens 364 includes 8 spacing posts 377, wherein each spacing post is positioned between a light post 376.
The lens 364 may comprise two or more embodiments disclosed herein.
H. Rubber Seal
In an embodiment, the safety light 10 includes a rubber seal 78, as shown in FIGS. 1 and 30-39.
The rubber seal 78 serves as a rubberized gasket that forms a watertight or semi-watertight seal between the lens 64 and the bottom housing 94.

In other embodiments, in particular, where the safety light 210 is configured for inductive charging, the recharging port 234 and the corresponding charging portion cover 290 may not be included, or they may be provided on another portion of the safety light (e.g., on the top housing 212 or a sidewall that extends between the top housing 212 and the bottom housing 294).
In an embodiment, the safety light 210 can be provided with one or more attachments 293 that can be configured to allow the safety light 210 to couple to a support structure, such as a mounting accessory (e.g., a bracket, clip, or strap) or an external device (e.g., an electrical device such as a computer or charger). In that regard, the attachments can be configured to provide one or both of a physical connection and an electrical connection. Accordingly, the attachments 293 can be configured to orient the safety light 210 relative to an attached mounting accessory or external device, to provide a secure connection between an attached mounting accessory or external device (e.g., electronic devices including, general purpose computers, phones, vehicles, docking terminals, etc.), and to allow for the communication of a data (e.g., communication signals, software, and firmware) and electrical power (e.g., electrical current). Relatedly, an attachment 293 can be provided as an insert that is embedded (e.g., inserted into or integrally formed in) the safety light 210, or it can be formed as a protrusion or other structure that extends from the safety light 210. The one or more attachments 293 can be provided anywhere along an outer surface of the safety light 210 and the specific arrangement may vary depending on the particular application. In some cases, attachments can be arranged to provide a universal mounting area as part of lighting system that allows the safety light 210 to couple to a wide array of mounting structures and external devices.
As shown in FIG. 81, in an embodiment, the bottom housing 294 includes a plurality of attachments 293 disposed along a bottom surface 298 (e.g., an external surface) of the bottom housing 294, which can be configured to provide one or more physical attachment points. Specifically, each of the attachments 293 is a threaded attachment 295 having an exposed end 297, as shown in FIG. 81. The exposed end 297 is open to the environment and is configured to receive a threaded article (not shown). A “threaded attachment” is a component sized to receive a threaded article, such as a screw or a post. The threaded article may be any threaded fastener disclosed herein, including threaded articles that are part of a mounting accessory or external device. The threaded attachment 295 enables the safety light 210 to be releasably attached to a threaded article. As one particular nonlimiting example, in an embodiment, the threaded article is a post attached to a bicycle or a boat.
A threaded attachment 295 can be integrally formed with the bottom housing 294 or a threaded attachment 295 can be a separate component that is coupled to the bottom housing 294 (e.g., by a press fit connection, a threaded connection, adhesives, co-molding, ultrasonic welding, or other types of connections as known in the art). As illustrated, the threaded attachments 295 are formed from one or more rigid materials, such as metals (e.g., brass, stainless steel, etc.) and polymers, which are embedded within the bottom housing 294 so that the respective exposed ends 297 are open along the bottom surface 298 or another exterior surface (e.g., a side or top surface) of the bottom housing 294. Specifically, the threaded attachments 295 can be optionally disposed within ears 213 formed as part of a bracket 211 for a magnet 108. In accordance with the positioning of the ears 213, the threaded attachments 295 are shown being (symmetrically) spaced around a perimeter of the magnet 108 (e.g., equally and/or and circumferentially spaced). In other embodiments, the threaded attachments 295 may be arranged differently and their arrangement may not depend on a position of a magnet. For example, the threaded attachments 295 may be provided in separate projections extending from the bottom housing 294 (e.g., along the bottom surface 298), or they may not be disposed within any projection at all, and may instead be provided in one or more recesses. Additionally, the threaded attachments 295 can be spaced symmetrically or non-symmetrically along the bottom surface 298 of the bottom housing 294. In some cases, the arrangement of the threaded attachments 295 can provide for specific mounting orientations or configurations (e.g., a first orientation and a second orientation rotated approximately 90 degrees from the first orientation, or at another angle from the first orientation). Accordingly, in an embodiment, the bottom housing 294 includes from 1, or 2 to 3, or 4, or 5, or more than 5 threaded attachments 295. FIG. 81 shows a bottom housing 294 with two threaded attachments 295.
As mentioned above, in an embodiment, attachments 293 can also be configured as electrodes (e.g., electrical attachments) that are configured to provide an electrical connection between the safety light 210 and a mounting accessory or another electrical device. As one particular example, the threaded attachment 295 can be brass threaded attachments that can provide both a physical connection and an electrical connection. As another example, in an embodiment shown in FIG. 85, the attachments 295 can be configured as electrodes 302 that are embedded into a bottom surface 298 of a bottom housing 294, such that an exposed end 304 of the electrode 302 is exposed to the environment. In the embodiment shown in FIG. 85, the there are four electrodes that are symmetrically spaced along the bottom surface 298 of the bottom housing 294, but the electrodes 302 can be arranged differently as required by a specific application. The electrodes 302 can extend through the bottom housing 294 to connect with a PCBA (not shown) and/or a rechargeable power source (not shown) of the safety light 210 (e.g., that are disposed within the safety light 210. In this way, the electrodes can be in electrical communication with one or both of the PCBA and a rechargeable power source, allowing an external device (e.g., a computer or charging delivery device) to communicate with safety light 210 and to charge the rechargeable power source. Relatedly, as shown in FIG. 86, in some cases, in particular, where electrodes can charge a rechargeable power source and allow an external device to communicate with the safety light, a separate recharging or communication port (e.g., recharging port 234, see FIG. 71) may not be included.
In an embodiment, a safety light may be provided with both attachments that are configured to provide a physical connection (e.g. a physical attachment, for example, a snap-fit, threaded, or magnetic connection) that secures the safety light to a mounting accessory, external device, other support structure (e.g., to a vehicle, a hard hat, a building, etc.), and attachments that are configured to provide an electrical connection (e.g., to send communication signals, to transfer electrical power, or to send data, including software and firmware). In that regard, attachments can be arranged into different groups to facilitate different types of connections when coupled to different type of mounting structures or external devices. As used herein, a “group” is defined to include one or more structures or elements. For example, in an embodiment, shown in FIG. 86, a bottom housing 294 includes two groups of attachments 293. In particular, the bottom housing 294 includes a first group of attachments 293a that includes threaded attachments 295 and a second group of attachments 293b that includes electrodes 302. In other embodiments, attachments can be grouped differently and may include, for example, both electrodes and threaded attachments.
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 66a of the lens 64, 264 and projects through the plurality of side surfaces 68, 268 of the lens 64, 264.
