| 20120069579 | Direct-lit light guiding structure, direct-lit light guiding panel and lighting device - A direct-lit light guiding structure, a direct-lit light guiding panel and a lighting device are disclosed. The light guiding structure includes a light transmissive body and microstructures; the light transmissive body includes an upper conical groove and a lower accommodating groove, and the upper conical groove has a curved surface with a continually varied slope; the microstructures are disposed on the light transmissive body. The lighting device includes a circuit board, a light source and the aforesaid light guiding structure; the light source and the light guiding structure are disposed on the circuit board, and the light source is accommodated within the lower accommodating groove. With these arrangements, the direct-lit light guiding structure can receive the light rays emitted from the light source, and then output the lights uniformly. Further, a plurality of direct-lit light guiding structures can be connected with one another to form the direct-lit light guiding panel. | 03-22-2012 |
| 20120069575 | LIGHT CONVERTING OPTICAL STRUCTURE AND LIGHTING DEVICE UTILIZING THE SAME - Embodiments of the present invention include a light converting structure, a light accommodating structure, and a lighting device. The light converting structure includes a bottom conical recess to accommodate a light source, and a top conical recess to distribute the lights emitted from the light source. The light accommodating structure includes a through hole with a small opening and a large opening. A light source is accommodated in the through hole at the large opening, and the lights emitted from the light source output at the small opening. The lighting device utilizing the light converting structure and/or the light accommodating structure obtains a thinner configuration. | 03-22-2012 |
| 20110292655 | LIGHT REFLECTIVE STRUCTURE AND LIGHT PANEL - A light panel is disclosed. The light panel comprises a circuit assembly, a plurality of light sources, a light reflective structure, and a diffuser layer. The light reflective structure has a plurality of concaves, which are continuously connected to form a plurality of ridges. Each of the concaves has an opening formed on the bottom surface thereof, and each of the light sources is disposed corresponding to each of the openings of the concaves. The diffuser layer is supported by the ridges of the light reflective structure. In some aspects of the present invention, the diffuser layer may have a sloping inner surface or is coated with patterned diffuser coatings on the top surface. Each light source can be added with a lens. | 12-01-2011 |
| 20110069496 | LIGHTING DEVICE, LIGHT SPREADING PLATE AND METHOD FOR MANUFACTURING THE SAME - A lighting device, a light spreading plate for the lighting device and a method for manufacturing the same are provided. The lighting device comprises a light source plate and the light spreading plate. The light source plate comprises a plurality of light sources. The light spreading plate comprises a light travelling layer formed with a plurality of light spreading units. Each of the light spreading units is formed with a main body being defined with a top surface, a bottom surface and a peripheral. The main body has a thickness being tapered towards the peripheral. The main body comprises a top surface having a cone-shaped recess and a bottom surface having a bowl-shaped recess. The cone-shaped recess and the bowl-shaped recess of each of the spreading units are opposite to each other, and one of the cone-shaped recess and bowl-shaped recess is fitted for one of the light sources. | 03-24-2011 |
| 20110068709 | LIGHTING DEVICE, LIGHTING PANEL AND CIRCUIT BOARD THEREOF - A lighting device, a lighting panel and a circuit board thereof are provided. The circuit board comprises a substrate; a plurality of light sources disposed on the substrate and at least one circuit layer, being patterned onto the substrate to form a plurality of traces for electrically connecting the light sources. Therein, the circuit board is capable of being assembled with other circuit boards to construct the lighting panel. The lighting device is capable of having the lighting panel of a large size by assembling a plurality of the circuit boards and individually controlling each light source disposed on the lighting panel so as to provide the function of local dimming. | 03-24-2011 |
| 20110006316 | LIGHTING DEVICE, DISPLAY, AND METHOD FOR MANUFACTURING THE SAME - A display, a lighting device and a method for manufacturing the lighting device are provided. The lighting device comprises a substrate, an electrode layer, a plurality of light source units and a light scattering layer, which is covered by a transparent layer and a reflector layer to create a uniform surface light within an ultra thin format. A yellow phosphor layer is disposed above the reflector layer to create white light when a blue LED or UV LED is used. The lighting device also provides a unique electrode layout design which can be applied for local dimming control and can be easily applied for large size product applications. | 01-13-2011 |
