Abstract: According to an embodiment, a lighting device includes a light source configured to irradiate light, a reflector configured to reflect the light from the light source, and a supporter disposed at a first end of the reflector and configured to support the light source, wherein the light source irradiates the light toward a second end of the reflector, and a reflection area of the reflector becomes larger from the second end of the reflector to the first end of the reflector.

Abstract: Provided is a light emitting diode (LED) lamp having a broad and uniform light distribution. The LED lamp having a broad and uniform light distribution includes a printed circuit board (PCB) on which a plurality of LEDs for emitting a light are mounted, a light transmitting unit that faces opposite to a side of the PCB on which the LED is mounted and forms a predetermined angle such that a light emitted from the LED is diffused in a different direction of a major light distribution corresponding to the predetermined angle, a PCB support unit that supports the PCB, and a power supply unit that supplies a power to the LED. The LED lamp according to the present invention is capable of evenly radiating a wide area, thereby replacing a conventional lamp not only in indoors such as a home or an office but also in outdoors.

Abstract: Disclosed is a field emission display device which can prevent mixing of colors between the phosphor elements of the field emission display device. In the field emission display device, an upper substrate and a lower substrate are spaced apart with a predetermined gap and opposed to each other. Cathode assemblies are formed in a shape of stripes on the lower substrate. Anodes are formed on the upper substrate, and black matrices are formed on the anodes. The black matrices are disposed at locations respectively corresponding to every space between the cathode assemblies, so as to respectively have a shape of a partition. R, G, and B phosphor elements are formed in spaces between the black matrices, so as to respectively correspond to the cathode assemblies.
