The second type LED chips integrated with the first fluorescent layer and the second fluorescent layer emit a second light. The first light and the second light have more than 30% overlapping.

An illuminated sensing edge assembly has an axially elongate, triple tiered body including a first track, a second track and a third track. The first track is configured to connect with a swing gate barrier arm such that the body underlies the barrier arm when mounted thereto. The second track is constructed of an at least translucent material. An LED strip axially extends through the second channel and is configured to emit light to notify individuals of the barrier arm. A sensing edge underlies the body and is secured to the third track. The sensing edge is configured to elicit a stoppage or reversal of a closing operation of the barrier arm upon a force being applied to the sensing edge.

A light emitting diode, LED, filament (110), configured to emit LED filament light, comprising an array of a plurality of light emitting diodes (120), LEDs, configured to emit LED light, a carrier (130) arranged to support the plurality of LEDs, at least one heat sink (140) arranged in thermal connection with the carrier for a dissipation of heat from the plurality of LEDs during operation, wherein the at least one heat sink comprises a base portion (150) extending parallel to the carrier, and a plurality of fins (160) projecting from the base portion, and an encapsulant (170) comprising a translucent material, wherein the encapsulant at least partially encloses the plurality of LEDs, the carrier and the at least one heat sink.

A mountable light may comprise: a light body having a clamping arrangement and a compartment with an opening at an end thereof; a light head assembly including a source of light, the light head assembly being configured to cover the opening of the compartment; the light body and the light head assembly each having a feature that engages the feature of the other for pivoting the light head assembly relative to the light body, e.g., for covering and uncovering the opening of the compartment; and a latch for retaining the light head assembly against the light body to cover the opening of the compartment. A source of electrical power can be placed into and/or removed from the compartment of the light body when the mountable light is mounted to an object, e.g., a firearm or other object or device, by the clamping arrangement.

Methods, systems, and devices for a vehicle light. The vehicle light may include a housing and a substrate coupled to the housing. The vehicle light may further include a plurality of LEDs coupled to the substrate. The plurality of LEDs may include at least two LEDs of a first color and at least two LEDs of a second color. The plurality of LEDs may be positioned on the substrate such that a left half or portion of the substrate mirrors a right half or portion of the substrate and/or a top half or portion of the substrate mirrors a bottom half or portion of the substrate with respect to a position and a color of each LED of the plurality of LEDs.

An emitter module for a light-emitting diode (LED) light source may comprise a substrate, and a plurality of emitters mounted to the substrate, where each emitter is configured to produce illumination at a different wavelength, and the number of emitters is greater than four (e.g., five emitters). The emitter module may also comprise a dome mounted to the substrate and encapsulating the plurality of emitters. Each of the plurality of emitters is arranged such that a center of the emitter is located on a circular center line that has a center that is the same as a center of the dome. Each of the plurality of emitters is located on a different primary radial axis of the emitter module. Each of the primary radial axes of the emitter module is equally spaced apart by an offset angle. The emitter module may also comprise an additional one of each of the emitters at each of the different wavelengths (e.g., ten total emitters).

A warning light having light sources for emitting light of different colors via at least a lens, where one of the colors is violet and other of the colors is non-violet along a spectrum of visible illumination. A controller selectably activates the light source(s) emitting non-violet light to provide visible warning signals, and the light source(s) emitting violet light to provide fluorescent inducing signals dominantly along the spectrum of visible illumination which causes any object or surface having phosphors to fluoresce in order to enhance their visibility in low or zero ambient light environments. The lens and/or optional filter, or coating along the lens, filters or blocks ultraviolet light to shift the peak wavelength of violet light source(s) so that fluorescent inducing signals are dominantly or more dominantly of higher wavelengths along the spectrum of visible violet illumination to human eyes. Single and dual warning light housings embodiments are provided.
