摘要： Methods, systems and devices associated with an electronic candle are disclosed. One example includes an electronic candle includes an outer shell including a through-hole, a light-emitting assembly including a flame sheet configured to protrude through the through-hole, an inner shell positioned within the outer shell, and a self-locking device positioned within a cavity of the inner shell. The self-locking device is configured to operate in (1) a locked state when a switch locks a spring in a compressed state and (2) an unlocked state when the switch releases the spring to be in a relaxed state. The electronic candle also includes a bottom case such that the bottom case is enclosed within the outer shell when the self-locking device is in the locked state and the bottom case is exposed to an external environment beneath the outer shell when the self-locking device is in the unlocked state.

摘要： The present invention addresses the problem of providing a video display device that projects and displays video including starry sky images onto a target surface, that can reproduce the twinkling of stars and that can more faithfully reproduce an actual starry sky. Provided are a light source, a projection lens, a starry-sky projection negative plate, a twinkling negative plate with uneven light-transmitting properties, a starry-sky-end support unit that supports the starry-sky projection negative plate in a location onto which light from the light source is radiated, a twinkling-end support unit that supports the twinkling negative plate between the starry-sky projection negative plate and the projection lens or between the light source and the starry-sky projection negative plate, and an actuation mechanism that rotationally actuates, by power from an actuator, the starry-sky projection negative plate in a state of being supported by the starry-sky-end support unit and the twinkling negative plate in a state of being supported by the twinkling-end support unit. Light that has penetrated the starry-sky projection negative plate and the twinkling negative plate is radiated onto the target surface via the projection lens.

摘要： A vehicle comprises: an interior; a light assembly capable of emitting light with both a first beam pattern and a second beam pattern to the interior, the light assembly comprising a light source, capable of emitting light in multiple colors, that emits light that exits the light assembly and enters the interior of the vehicle with either the first beam pattern or the second beam pattern; and a controller that controls whether the light that exists the light assembly and enters the interior of the vehicle has either the first beam pattern or the second beam pattern and controls which color of the multiple colors the light source emits. The vehicle can further comprise a user interface in communication with the controller, wherein the user interface is usable from the interior and allows a passenger of the vehicle to select a color of the multiple colors of the light.

摘要： The invention describes a laser-based light source (100) which is adapted to use the angular dependence of the reflection of polarized laser light (10) at a surface of a conversion material to control especially the color point of light emitted by means of the laser-based light source (100). The reflected laser light is within a first wavelength range and the converted light is in a second wavelength range different from the first wavelength range such that the color point of the light emitted by means of the laser-based light source (100) in a defined solid angle depends on the ratio between reflected and converted light. The invention further describes a corresponding method of light emission control, a vehicle headlight (200) comprising such a laser-based light source (100) and a lighting system comprising such vehicle headlights (200).

摘要： A flame simulator includes a light beam source that projects a beam of light, a flame screen, a light beam mover that imparts movement to at least a part of the light beam source, and a range limiter. The light beam source includes a light source adapted to produce light and at least one light conditioner adapted to act on the light from the light source to produce the beam of light with a color, size and shape that mimics a flame when the beam strikes the flame screen. The range limiter is operatively associated with the light beam source so that the beam of light, when being projected, strikes at least a portion of the flame screen and causes illumination of the flame screen by the beam of light.

摘要： An iris diaphragm comprises a stationary ring, a rotatable adjusting ring, and a plurality of shutter blades. The plurality of shutter blades forms a diaphragm aperture inside the stationary ring and rotation of the adjusting ring moves the shutter blades inside the stationary ring whereby the size of the diaphragm aperture can be changed. The shutter blades are formed as a flat opaque surface and at least one of the shutter blades comprises at least one transparent region formed in said opaque surface. A light fixture comprises such iris diaphragm arranged between a light source generating a light beam and an optical assembly configured to project the light beam along an optical axis.
