Described herein is an earplug having a lighting element. The earplug comprises a first end with a removable tip and a second end having a light source configured to illuminate the second end and at least the ear, wherein the light source illumination indicates the presence of the earplug being worn and placed properly. The light source is preferably a color changing light emitting diode (LED).

A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

A light-emitting system (1000) removably attachable to headgear is provided, which comprises: a form factor (1010) configured to surround a portion of the headgear when the light-emitting system (1000) is removably attached to the headgear for use; a plurality of halo lighting elements (1100) configured to selectively generate at least a partial halo of light that radiates outwardly away from the light-emitting system; and at least one task lighting element (1120) aligned in a direction along a task light axis (1130) that is fixed and oriented downwardly at an oblique angle (α) relative to a transverse plane (TP) of the light-emitting system (1000), the at least one task lighting element (1120) being configured to selectively generate flood task lighting in an area in front of a user.

A handheld flashlight includes a hollow cylinder having a first end and a second end, and a rechargeable battery therein. The handheld flashlight further includes a lamp head with a light source, a window breaker, a charging port and a discharging port, selectively connected to an external power source or an external load; a connection port, selectively connected to positive and negative terminals of a vehicle battery through external cables; and a management circuit, selectively applying power from the battery to one or more of the light source, the discharging port, and the connection, and selectively charging the battery from the external power source through the charging port; wherein the handheld flashlight is of such compact size and low weight as to be suitable for single-handed portable operation by a user.

A multi-purpose illumination, self-defense and glass-breaking tool, the tool comprising: a tool body; a handle projecting from the tool body; a flashlight carried by the tool body; a pepper spray unit carried by the tool body; and a glass breaker carried by the handle.

A light emitting apparatus including a first light emitter including at least one first light emitting diode and a wavelength converter, and a second light emitter including at least one second light emitting diode, in which the first light emitting diode emits light having a central wavelength in a range of violet or blue, the second light emitting diode emits light having a central wavelength in a range of about 400 nm to 420 nm, the wavelength converter includes green and red phosphors to convert light of the first light emitting diode into the white light, in the white light, an irradiance of light emitted from the first light emitting diode is less than that from the red phosphor, and an irradiance of light emitted from the second light emitting diode is greater than that of the white light emitted from the first light emitter at the same wavelength.

A lamp assembly having a light source and a sanitizing system. The assembly can be formed of various differing configurations to correspondingly provide one or more systems for sanitizing the surrounding air. Some of the applicable sanitizing systems are configured to be adaptable to provide differing levels of performance in order to provide the warranted sanitizing effectiveness in efficient manners when using the assembly.

An LED (light-emitting diodes) light hose reel is disclosed, comprising a housing (10); a reel (12) inside the housing (10); a transparent hose (20), the hose (20) being retractably reeled on the reel (12) inside the housing (10); an LED light strip (22) arranged inside the hose (20); an electric power cable (34) for the LED light strip (22); and an electric connection (36) between the LED light strip (22) and the electric power cable (34). A method of storing an LED light strip is disclosed, comprising storing the LED light strip on a retractable reel. A method of using the LED light hose reel is disclosed. The method comprising the following steps in any order: withdrawing the hose (20) from the LED light hose reel; selecting light colour and selecting blinking or constant light by activating the control element (32); attaching the hose (20) to an object; and retracting the hose (20) into the LED light hose reel.

A lighting device includes a plurality of LED light sources, a plurality of lens parts respectively disposed on front surfaces of the plurality of LED light sources to collect and irradiate light emitted from each of the plurality of LED light sources, and a controller for controlling operations of the plurality of LED light sources, wherein the plurality of LED light sources include visible-light LEDs and at least one ultraviolet LED and each of the plurality of lens parts includes a condensing lens disposed on the front surface of each of the plurality of LED light sources to decrease a divergence angle of light emitted from each of the plurality of LED light sources and a fly eye lens part disposed on a front surface of the condensing lens to stack the light on a light receiving surface.

A light tube apparatus includes a tubular housing, a first light source, a second light source, a driver and a controller. The tubular housing having a first light passing window and a second light passing window. The first light source is for emitting a white light from the first light passing window in an illuminating mode. The second light source is for emitting an ultraviolet light from the second light passing window in a sanitizing mode. The driver is for converting an external power source to a first driving current to the first light source and a second driving current to the second light source. The controller is for determining when to enter the sanitizing mode or the illuminating mode based on a stored criterion.
