The present disclosure describes a liquid crystal display device. The liquid crystal display device includes a substrate and a plurality of light sources disposed on the substrate and configured to generate excitation light. The liquid crystal display device includes a quantum dot film disposed in a light-emitting direction of the plurality of light sources and a plurality of stereoscopic reflecting plates disposed on the substrate. The liquid crystal display device includes an optical layer disposed between the plurality of light sources and the quantum dot film. The plurality of stereoscopic reflecting plates and the plurality of light sources form a plurality of cavities arranged in an array. The plurality of light sources are located on bottoms of the plurality of cavities respectively. The optical layer is disposed between the plurality of cavities and the quantum dot film, and configured to partially transmit and partially reflect the excitation light. The quantum dot film is configured to be excited by the excitation light to generate excited light.

An industrial electronic apparatus includes a display panel that includes a design portion including a character or a graphic, and a light source provided behind the display panel. The display panel includes: a transparent plate having a back face located on the light source side and a front face located on a side opposite to the light source side; a light shielding portion that is located on the back face side of the transparent plate, covers a portion, of the back face, that does not correspond to the design portion, and includes a window that is formed at a portion, of the back face, that corresponds to the design portion, and a light diffusing portion that is located on the back face side of the transparent plate, and covers a portion, of the back face of the transparent plate, that corresponds to the design portion.

A light distribution method for an advertising lamp box and an advertising lamp box are disclosed. The light distribution method comprises a step of edge lighting and a step of middle lighting, comprising: lighting from an inner wall of a frame to the middle, and lighting on two sides in the middle of the inner portion of the advertising lamp box. With the same effect as conventional lighting tools, the light distribution method of the present invention has the advantages of environmental friendliness, firmly fixed lenses which are not easy to fall off, high structural strength enough to be applied to large lamp boxes, low labor cost of mounting, and so on.

Systems disclosed herein are directed to a powered retail signage assembly having, inside a housing, a multi-layer translucent indicia panel and a light source panel emitting light to the rear of the multi-layer translucent indicia panel. The multi-layer translucent indicia panel includes a front tinted layer forming an indicium exposed on a front surface of the housing and a rear diffusion layer laminated with the front tinted layer at the back of the front tinted layer. The light emitted from the light source panel is diffused by the diffusion layer and transmitted through the tinted layer. The indicium appears brighter or darker than the front surface of the housing based on an external light condition.

The invention relates to a retractable lighting fixture, comprising an elongated drum rotatable over a length axis; and a flexible multilayer lighting sheet movable between a retracted position and a protracted position, with the multilayer lighting sheet in the retracted position being at least partially retracted in one or more windings around the drum and with the multilayer lighting sheet in the protracted position being fully unwound from the drum; the multilayer lighting sheet being composed of at least one LED layer and at least one diffusing optical layer, the at least one LED layer having a first LED layer edge mounted at a first mounting position of the drum and the at least one diffusing optical layer having a first optical layer edge mounted at a second mounting position of the drum, the first mounting position being located at an arc length from the second mounting position.

A lighting label that adheres on a curved surface of a container. The lighting label includes a translucent layer, an illuminating layer, a flexible printed circuit and a waterproof sealant. The illuminating layer includes a plurality of light emitting diodes (LEDs) and a light guide panel. The light guide panel connects to the LEDs and includes dots that scatter the light generated from the LEDs. The waterproof sealant seals an edge of the lighting label and is transparent to illuminate with the light around the edge of the lighting label.
