Systems and methods for determining lighting fixture arrangement information (e.g., position and/or orientation). A lighting beam from the lighting fixture is directed among three discrete locations on a reference surface (e.g., by a controller). The fixture's position is determined using perspective inversion based on angular changes of the lighting fixture and coordinate data of the discrete locations (e.g., determined using a camera and a reference point on the surface). Distances from the fixture to the three discrete locations are estimated based on perspective inversion. The position of the lighting fixture is trilateralized based on the distances. Spherical coordinates of the fixture's orientation relative to the reference surface are determined, and yaw, pitch, and roll of the fixture are extracted.

An LED candle light includes an outer housing, a battery pack provided at an inner bottom portion of the outer housing and controlled by a power control board, a coil provided above the battery pack, a mounting frame fixed in the outer housing, an LED light fixed on the mounting frame, the LED light being electrically connected with the battery pack, a flame cover covering an outer periphery of the LED light, a pendulum connected with a lower portion of the flame cover through a rotating shaft, and a magnet provided at a bottom portion of the pendulum, the magnet being located directly above the coil. The present disclosure can simulate a candle and is energy-saving, environmentally friendly, greatly amusing, highly ornamental, safe and harmless.

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.

Disclosed are a candlewick and an electronic candle. The candlewick includes a candle flame sheet, a light-emitting element, a left support, and a right support. The left support and the right support are assembled to constitute a flame sheet support. The light-emitting element is mounted in the flame sheet support. A first support beam for supporting the candle flame sheet is disposed in the left support. An upward-facing first support portion is formed at one end of the first support beam. A downward-facing limiting opening is formed at a lower portion of the candle flame sheet. A top end of the first support portion abuts against a top wall of the limiting opening.

A flameless candle includes a candle body, a light source, and a flame element. The candle body includes an inner region and an upper surface including an aperture. The light source is energized and de-energized selectively to control whether or not a light is emitted. The light emitted by the light source is emitted towards the interior region of the flame element, such that it passes through the interior region and onto the interior surface. The flame element is at least partially transparent or translucent, such that it permits the light to propagate through the flame element and outwardly from the exterior surface. While the light is emitted, the flame element moves with respect to non-moving portions of the candle body. While the light is emitted, at least a portion of the flame element extends through the aperture in the upper surface.

The invention relates to the field of illumination technology and provides an electric scented candle, which comprises the base, the hollow filled body having two ends respectively formed with the opening, the fragrance assembly and the candle tip, wherein the fragrance assembly is arranged in the receiving cavity of the base, the fragrance assembly comprises the solid perfume and the heating mechanism for heating the solid perfume, the base is detachably connected with the filled body, the holding plate is arranged in the filled body, and the candle tip is arranged in the filled body and extends through the though-hole to a position above the holding plate. Real burning flames can be simulated by the candle tip, and wax surface of real burning candles adjacent to the candle tip can be simulated by the layer of paraffin arranged on the holding plate, providing better simulation effect of the scented candle.

Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame piece or element that extends upwardly from a body of the device. A light source can be disposed with respect to the flame piece such that the flame piece is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame piece with respect to the body or housing. The flame piece can be coupled to a body or housing of the device using various components to suspend at least a portion of the flame piece within the body or housing.

The present invention relates to a movable flame assembly comprising: a simulated flame element; a transmission element for disposing and actuating the simulated flame element; an elastic element directly or indirectly connected to the simulated flame element and supporting the simulated flame element and the transmission element; and a power source for driving the transmission element. The invention further relates to a simulated flame device comprising the movable flame assembly.

An electric candle device that resembles a real was candle includes an outer shell with an uneven edge around the top of the outer shell. The device includes one or more light emitting elements positioned within a cavity inside the outer shell and that emit beams at a non-zero angle with respect to a longitudinal axis of the electric lighting device to provide illumination from within the cavity in an upward direction and reaching above the top surface after passing through the opening. An optical element is positioned to receive light from the one or more light emitting elements and to direct the received light toward the top surface. The optical element has a focal point to change one or both of a size and direction of the light received prior to projecting the light in the direction of the top surface.

Various embodiments of electric lighting devices and, in particular, electric candles are described. The devices can include a flame element onto which light can be projected from a light source. Preferably, the light is projected within a focal area on the flame element. The housing of the devices can include projections that help maintain a vertical position of a circuit board within the housing.
