A candle device with a solid candle wax and a permanent display is provided. In preferred embodiments the candle device is reusable. In other preferred embodiments the candle device contains an LED device capable of providing LED light to the candle device.

Systems and methods for improving the brightness of a transparent display are disclosed herein. One embodiment collects ambient light using an array of diffraction gratings disposed on an external surface of a vehicle to produce filtered ambient light; collects internal light from the vehicle's headlights; filters the internal light to produce filtered internal light; generates primary-source light using a light-emitting-diode (LED) light source; and injects, into a transparent edge-lit liquid crystal waveguide display deployed in at least a portion of a window of the vehicle, the primary-source light, the filtered ambient light, and the filtered internal light in a color-synchronized manner. The filtered ambient light and the filtered internal light improve the brightness of the transparent edge-lit liquid crystal waveguide display.

A structure and method for utilizing natural light indoors or in the interior in a moving space are disclosed. The structure includes: at least one natural light condenser configured to reflect the natural light; a natural light transmitter configured such that the natural light reflected by the at least one natural light condenser is moved to the natural light transmitter; a smart lamp unit including an artificial light generator; a smart lamp driver located adjacent to the smart lamp unit and configured to move the smart lamp unit; and a controller connected to the at least one natural light condenser, the natural light transmitter, the smart lamp unit, and the smart lamp driver so as to transmit and receive information therewith. The controller is configured to combine artificial light with the natural light in response to a user request signal to radiate a combination of the artificial and natural light.

The invention relates to a lighting device for at least one plant, comprising an artificial lighting unit for providing artificial light for lighting the plant; a sunlight unit for providing sunlight for lighting the plant; a mixing unit for generating a mixed light consisting of the artificial light and the sunlight; a distributing unit for distributing the mixed light and lighting the plant with the distributed mixed light; and an adjustment unit for adjusting a property of the mixed light. The invention provides a lighting device for at least one plant, i.e., one or more plants, wherein the device can be used in an energy-saving manner for indoor farming.

One example embodiment is a photosensitive candle comprising: (a) a candle container comprising an opening; (b) a candle component disposed in the candle container, comprising: a candle body having a surface proximate to or substantially aligned with the opening; a wick with an exposed portion protruding out of the surface of the candle body; and an optical fiber embedded in the candle body and positioned juxtapose to the wick for transmitting flame lights of the wick, wherein the optical fiber comprises a first end proximate to the exposed portion of the wick and an opposing second end; (c) a lighting control component disposed in the candle container, comprising: a casing comprising an interior cavity; a controller and a power source disposed within the interior cavity; and a light sensor connected to the controller, comprising a photosensitive element proximate to the second end of the optical fiber to detect light transmitted therefrom; and (d) at least one light-emitting device connected to the controller. In some embodiments, the controller is configured to receive light signals associated with the flame lights of the wick from the light sensor, and control the at least one light-emitting device based on the received light signals.

A solar mounting frame for a ventilator apparatus includes: a solar mounting frame having four sides mounted to the ventilator; and a side solar mounting frame having two L-shaped angle rails to mount a solar panel.

An ignitable electronic candle including a candle body and an electronic luminous part is provided. The electronic luminous part that includes a light-transmitting shield, a first luminous body, an electronic control unit and a power supply is set below the candle body. The first luminous body is located near the center of the lower surface of the light-transmitting shield. A light guide body wrapped in an ignitable sleeve is installed in the middle of the upper surface of the light-transmitting shield. The light guide body and the ignitable sleeve pass through the candle body above the light-transmitting shield and extend out of the upper surface of candle body. The first luminous body is electrically connected with the power supply through the electronic control unit. The ignitable sleeve can be lit like a candle wick to make the electronic candle function as a traditional candle.

An interior lighting system has arrangement of lighting panels mounted around a window for providing lighting around the outside of the window. The light provided depends on the exterior lighting which passes through the window. In this way, contrast between the window and the wall around the window can be reduced.
