A lighting device capable of improving yield by relaxing a selection requirement for turquoise blue and making chromaticity uniform is provided. The lighting device (100) includes a first light-emitting element (12a) that emits first light belonging to a first chromaticity rank, a second light-emitting element (12b) that emits second light belonging to a second chromaticity rank, and a light mixing unit (20) that mixes the first light and the second light and radiates the light as radiated light to an outside, wherein the first chromaticity rank and the second chromaticity rank are different from each other, and the radiated light is within a chromaticity range of turquoise blue.

A dynamic display apparatus is provided, including a simulation unit and a control unit. The simulation unit comprises a plurality of light-emitting elements (e.g. light-emitting diode beads) that are spatially arranged on a platform (e.g. flexible circuit board) to form one or more simulated moving tracks of one or more objects to be simulated. The control unit is communicatively coupled to the light-emitting elements, and controls an ON/OFF state, an ON/OFF frequency, an ON/OFF duration, and/or a light intensity of each light-emitting element such that lights emitted therefrom compositely mimic at least one motion state of the objects. The dynamic display apparatus can be used to mimically display complex effects, such as the flying and flashing effects of fireflies.

A multispectral illumination device includes a main housing configured to be secured to a helmet and an illuminator head comprising a plurality of light sources, the plurality of light sources operable to emit light in multiple spectral regions. A selector is located on the main housing for actuating one or more of the light sources within the plurality of light sources that emit light in a selected one of the multiple spectral regions. A stalk passes through an opening in the main housing and has a first end coupled to the illuminator head and a second end opposite the first end received within the main housing. The stalk is slidable within the opening in the main housing to extend and retract the illuminator head toward and away from the housing, the stalk being slidable between a fully extended position and a fully retracted position.

A light source device includes: a first light emitting element having a maximum junction temperature at a first temperature; a second light emitting element having a maximum junction temperature at a second temperature higher than the first temperature; a third light emitting element having a maximum junction temperature at a third temperature equal to or higher than the second temperature; a first heat sink to which the first light emitting element is thermally connected; and a second heat sink to which the third light emitting element is thermally connected.

An illuminated bike horn includes a ring attached to a mouth of the bike horn. The illuminated bike horn further includes a light source and sound sensor coupled between the bike horn and the ring. The light source provides illumination in response to the bike horn emitting sound generated in response to movement of a diaphragm coupled to a bell of the bike horn. The light source is a light emitting diode (LED) configured to provide illumination in a plurality of colors. The LED provides illumination for a predetermined period of time during and after the bike horn emits sound. The light source and sound sensor are powered by batteries. The batteries, light source, and sound sensor are secured to bay of a back side of the ring between the bay and a cover. The illuminated bike horn further includes a clamp to attach the bike horn to a handlebar.

A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area.
