20080203423 | LIGHT-EMITTING DIODE - A light-emitting diode is provided which includes: a sheet-like substrate; a pair of electrode patterns formed to wrap round and cover substantially entire upper and lower surfaces of the substrate, said pair of electrode patterns comprising an upper electrode portion, a lower electrode portion and a side electrode portion; a light-emitting element mounted on at least one of the electrode patterns; and a translucent sealing resin body that seals the light-emitting element. The pair of electrode patterns are separated by spaces formed therebetween, and substantially the entire surfaces of the substrate, except the spaces, are covered with the electrode patterns. | 08-28-2008 |
20080218470 | DISPLAY APPARATUS - A display apparatus includes an image display body having a front surface that rewritably displays image information and a light unit that illuminates the front surface of the image display body. The light unit has a light source and a light-transmitting sheet-shaped first lighting member superimposed over the front surface of the image display body. The first lighting member receives light from the light source and emits the light toward the front surface of the image display body to illuminate the front surface. | 09-11-2008 |
20100284194 | LENS MEMBER AND OPTICAL UNIT USING SAID LENS MEMBER - A plate-shaped lens member has concentric annular prisms each including an inner annular surface divided from a light-entrance surface of a conventional TIR lens and an outer annular surface divided from a light-reflection surface of the TIR lens in which the light-entrance surface has a concave shape provided in a lower portion of the TIR lens and the light-reflection surface has a convex shape positioned at a peripheral side of the TIR lens to surround the light-entrance surface. The light-entrance surface and light-reflection surface of the bulky TIR lens are Fresnel-ized or divided into a set of concentric annular prisms on a surface of the plate-shaped lens member and positions of divided portions from the TIR lens are efficiently arranged on the surface of the plate-shaped lens member. | 11-11-2010 |
20120075870 | LENS MEMBER AND OPTICAL UNIT USING SAID LENS MEMBER - A lens member includes a central axis, a light-incident side including a Fresnel-lens surface provided with a plurality of annular prisms concentrically arranged with respect to the central axis, and a light-exit surface opposite to the light-incident side. The Fresnel-lens surface further includes an annular lens portion that is concentrically arranged with respect to the central axis and that is extended to be longer and wider than the plurality of annular prisms. Provided is an optical unit in which a light source and a lens member are combined, and parts are disposed in a space provided in an outer periphery of the annular lens portion. | 03-29-2012 |
20120250313 | PLANAR LIGHT-EMITTING DEVICE - A planar light-emitting device includes a first reflecting surface, a rectangular support disposed adjacent to the first reflecting surface, light sources each including a light-emitting surface and disposed along, at least one side portion of the rectangular support, and a lens including a light-receiving surface disposed to face the light-emitting surfaces of the light sources, and configured to introduce light emitted from the light sources into a space that is demarcated by at least the first reflecting surface and the rectangular support. | 10-04-2012 |
20130033186 | LIGHT EMITTING DEVICE - Provided is a light-emitting device that aims not to affect a service life and characteristics of light emission by releasing heat from a substrate on that a plurality of LED elements mounted, and the LED elements generate the heat. | 02-07-2013 |
20130037847 | LAYERED SUBSTRATE, LIGHT-EMITTING DIODE INCLUDING THE LAYERED SUBSTRATE AND LIGHTING DEVICE USING THE LIGHT-EMITTING DIODE - A layered substrate includes a first substrate including an upper surface, a lower surface, a peripheral surface between peripheral edges of the upper surface and the lower surface, and a cut portion cut into the peripheral surface and passing through the upper surface and the lower surface, and a second substrate including an upper surface, a lower surface, and a peripheral surface between peripheral edges of the upper surface and the lower surface, and the lower surface of the second substrate layered on the upper surface of the first substrate and closing the cut portion of the first substrate from above. The second substrate includes a heat conductor that is thermally connected to an element to be mounted on the upper surface of the second substrate, the heat conductor configured to thermally extend to the cut portion of the first substrate. | 02-14-2013 |
