In one aspect, an exterior lighting insect zapper includes a photosensor configured to sense an amount of light for turning on or off an exterior light and an insect zapper coupled to the photosensor. The exterior lighting insect zapper also includes a twist-lock plug compatible with a receptacle of an exterior light for a photosensor unit plug, such that the exterior lighting insect zapper can replace existing photosensors of exterior light fixtures.

A light source for a spotlight (100) for illuminating a film, studio, stage event and/or theatre environment comprises a carrier (10), which is designed at least in part as a single-layer circuit board, a plurality of LEDs (12) with N>2 different colour types and a current line system (14) with a plurality of lines (141, 142) with N line types for supplying the LEDs (12) being arranged on the carrier (10).

The skin therapy device combines the mechanical stimulation and cleansing in the form of vibration with optical stimulation from LEDs. The device combines these two elements without sacrificing the effectiveness of either the mechanical cleansing/stimulation or optical stimulation by passing the light through the mechanical elements that are in contact with the skin. The light from the LEDs does not pass around the mechanical elements, such as around opaque brush fibers, but passes through the mechanical elements.

A lighting apparatus for bacterial, fungal and viral disinfection is provided comprising: at least one first element that emits light comprising a peak emission wavelength between at least about 411 nm to up to 419 nm; and at least one second element that outputs and/or converts at least a portion of the light emitted by the first element.

A light fixture, e.g., as an artificial skylight, in which light within a region defined by x, y color coordinates (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14) exits a first light engine, and light within a region defined by coordinates (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits a second light engine. Also, light fixtures in which a second light engine comprises a sidewall, and light exiting a first light engine passes through space defined by the sidewall; light fixtures in which first and second light engines are able to output light providing different CS values at a luminance; light fixtures in which light incident on a surface of the fixture and cumulative light exiting the fixture have different color points; light fixtures in which light distribution characteristics of light engines differ; and/or other features. The invention also relates to corresponding methods.

The disclosure relates in general to illuminated panels resembling windows, and more particularly, to a system containing a light source, a diffuser and a panel combined in such a fashion as to resemble a window, skylight or curtain wall.

A light-emitting seat, comprising a chair frame, a furniture light-emitting assembly, and a skin layer. The furniture light-emitting assembly comprises a fixing part, a strip light, a light guide material layer, and a power supply assembly. The strip light is disposed on the fixing part, the light guide material layer covers the strip light, and the power supply assembly is electrically connected to the strip light. In addition, the fixing part of the furniture light-emitting assembly may cover the chair frame, and the skin layer covers the chair frame and the furniture light-emitting assembly; or, the fixing part may be disposed on the light guide material layer, and the light guide material layer covers the chair frame, the skin layer covers the chair frame and the furniture light-emitting assembly. And, at least an area of the skin layer covering the furniture light-emitting assembly is a light-transmitting material.

Lighting system including visible-light source, optical system, mounting system, and control system. Visible-light source includes plurality of semiconductor light-emitting devices (SLEDs) and selectably generates: visible-light emissions having cyan-ish color point; and visible-light emissions having orange-ish color point. Optical system and mounting system are integrated with visible-light source. Optical system is arranged to combine together, into combined light emissions, visible-light emissions from SLEDs among plurality of SLEDs. Mounting system is arranged for directing combined light emissions as up-light emissions. Control system is coupled with visible-light source and selectably causes visible-light emissions to have cyan-ish color point or orange-ish color point. Control system and optical system cooperatively form combined up-light emissions as having dynamic spectrum for emulating orange-ish sky color at time of day selected to represent sunrise sky or to represent sunset sky, changing over time for emulating cyan-ish sky color at another time of day selected to represent mid-day sky.

A makeup mirror display with multiple cameras and variable color temperature light source includes an adjustable makeup mirror, a makeup mirror display, at least two cameras, and at least one variable color temperature light source. The makeup mirror display is arranged at one end of the adjustable makeup mirror surface and includes at least one control button and a control circuit arranged therein. The at least two cameras are respectively arranged on a left side and a right side of the makeup mirror display and electrically connected with the makeup mirror display. The at least one variable color temperature light source is disposed on one side of the makeup mirror display and electrically connected with the makeup mirror display. Therefore, the user can perform makeup more efficiently and finish a more perfect makeup, so as to enhance the overall practicability and convenience.

A light emitting device includes one or more light emitting elements and a plurality of fluorescent materials, and emits a first light, a second light, and a third light, wherein the first light has a correlated color temperature between 1,500 K and 3,500 K and a color rendering index R9 of 50 or more, the second light has a correlated color temperature between 3,500 K and 5,500 K and a color rendering index R9 of 50 or more, the third light has values of X and Y coordinates in the chromaticity diagram of the CIE1931 color system smaller than the values of X and Y coordinates at a color temperature of 5,500 K on the black body radiation locus, and a light having a correlated color temperature of 6,500 K has a color rendering index R9 of 50 or more and a melanopic ratio of 1.0 or more.
