Abstract: A three-dimensional light box includes a light source including a light guide panel and a light-emitting device for emitting light into the light guide panel, and a signboard including multiple signboard sheet members arranged in a stack on the light-emitting surface of the light guide panel. Each signboard sheet member includes a positioning sheet made of a light-emitting material and a picture layer coated on the positioning sheet. When the light-emitting device emits light through the light guide panel and the signboard, the picture layers of the signboard sheet members create a sense of three-dimensional hierarchy.

Abstract: A combination signboard having the characteristics of low cost, ease of fabrication, maintenance and replacement is disclosed to include a signboard body having multiple through holes, multiple display devices detachably mounted on the signboard body, each display device including a mount having a recessed portion and multiple countersunk holes located in the recessed portion, a light guide plate positioned in the recessed portion, a light source module sandwiched between the light guide plate and the recessed portion and connection members made in the form of a screw bolt and respectively mounted in the countersunk holes of the mount, and locking members made in the form of a screw nut and respectively threaded onto the screw bolt-shaped connection members to detachably lock the display devices to the signboard body.

Abstract: A light-emitting signboard includes a light guide plate having a light-emitting region on a front surface thereof and a plurality of light diffusing portions located in the light-emitting region and configured to refract and diffuse light, and a light source configured to emit light into the light guide plate through one peripheral edge thereof. The total surface area of the light diffusing portions is larger than or equal to one half of the surface area of the light-emitting region, and, the density of the light-emitting regions in the light diffusing portion at the area adjacent to the light source is smaller than the density of the light-emitting regions at the area far from the light source.

Abstract: A light guide panel includes a panel body having incident edges extending around the periphery thereof and a strong light region defined in a front surface thereof, and a light guide structure including a plurality of transversely extended first light-guiding grooves located in the front surface of the panel body and longitudinally spaced from one another at a predetermined interval, each first light-guiding groove having a first peak value area facing toward said strong light region and two first valley value areas located at two opposite ends of the first peak value area, each first peak value area curved in direction from the incident edges of the panel body toward the strong light region, the gap between the first peak value areas of each two adjacent first light-guiding grooves being gradually reduced in direction from the incident edges toward the strong light region.

Abstract: A lighting device with uniform illumination includes a lamp holder including an electric connector, a heat sink mounted at the electric connector and a light-emitting diode located in the heat sink, and a light guide prism including a reflective layer and a light-incident surface respectively located at two opposite ends thereof, a light-emitting surface extending around the periphery thereof and a plurality of recessed refractive surface portions located in the light-emitting surface for refracting and diffusing light that is emitted by the light-emitting diode through the light-incident surface and then reflected by the reflective layer so that the light guide prism can provide enhanced uniformity and brightness of lateral illumination. Further, the lighting device is easy to fabricate.

Abstract: A light-emitting clothing structure includes a clothing body, a light emitting unit movably coupled to the clothing body, and a connecting unit disposed between the clothing body and the light emitting unit. The connecting unit is configured to mount the light emitting unit on the clothing body. The light emitting unit emits light to achieve an anticipated aesthetic appearance and alert effect, when the light-emitting clothing structure is worn by a user.

Abstract: A lamp includes a frame; a light emitting mechanism coupled to the frame, the light emitting mechanism comprising a carrier, a plurality of dents disposed on the carrier, light-emitting diodes disposed in the dents, respectively, and series-connected to each other, and a power supply unit connecting with the light-emitting diodes; a lampshade coupled to the frame and configured to hermetically seal the light emitting mechanism; and a plurality of lenses coupled to the lampshade, or coupled to the dents and configured to hermetically seal the light-emitting diodes, respectively. The light-emitting diodes generate light directed to a required position by the lenses due to the directivity of the light-emitting diodes and focused by the lenses, such that the lamp is advantageously characterized by a large illumination angle and capable of saving power.
