A lighting device comprising at least one non-white light source, at least a first supplemental light emitter and at least a second supplemental light emitter. The non-white light source(s) is outside an area from 0.01 u′v′ above to below the blackbody locus, and within an area defined by curves between saturated light of wavelength 430-480 nm and 560-580 nm and line segments between saturated light of wavelength 430-580 nm and 480-560 nm. The first supplemental light emitter(s) have dominant emission wavelength of 465-540 nm. The second supplemental light emitter(s) have dominant emission wavelength of 600-640 nm.

A lighting device comprises a serpentine shaped CCFL, a driver driving the CCFL, a connector that allows the device to connect to and receive power from conventional power sockets, and a fixture that connects them into a single device. Such device can be used for general lighting purposes and replaces incandescent and other fluorescent lamps in current use without having to change electrical sockets. The fixture mechanically connects the CCFL, the driver and the connector to form an unitary mechanical structure. Preferably an air gap is maintained between the CCFL and the driver.

Light emitting systems and method of fabricating the same are disclosed. The light emitting system includes two or more monolithically integrated luminescent elements. Each luminescent element includes an electroluminescent device and a dedicated switching circuit for driving the electroluminescent device. At least one luminescent element includes a potential well for down converting light emitted by the electroluminescent device in the luminescent element.

A light bulb includes a bulb body, a light guide, and at least one light-emitting diode (LED). The bulb body includes a light-transmitting shell and a conductive base. The light-transmitting shell is mounted to the base. A circuit board is fixed at one side of the base and is in electrical connection with the base. The LED is mounted to the circuit board that is arranged at one side of the base, and the LED is in electrical connection with the circuit board to provide an internal light source. The light guide is arranged inside the bulb body and has an end forming a cavity that receives the LED therein, whereby the light guide is set erect on the base. As such, advantages of easy manufacturing, reduced costs, operation safety, increased angular range of illumination, and extended lifespan can be provided.

A double-sided display device includes a pair of substrates, on which self-emitting elements are formed respectively, being bonded to each other. A lead wiring section of the self-emitting element area formed on one of the substrates and a lead wiring section of the self-emitting element area formed on the other substrate are formed on the same side of the substrates. Each of the lead wiring sections is formed in a part of the side of each of the substrates. In addition, cutout portions are formed in parts of the sides of the substrates where the lead wiring sections are not formed. Thus, in the double-sided display device, the lead wiring sections formed on ends of substrates can be easily connected with a driving circuit component, a wiring substrate or the like, while the space for the double-sided display device can be reduced.

A circle type LED lighting flood lamp using a nano spreader is provided, which can provide a double heat dissipation structure formed by mounting an extended nano spreader having high heat diffusion on the inside of a circular type upper cover and making the extension parts of the nano spreader in contact with a heat dissipation portion in both directions, and prevent a heat dissipation plate from exposing to an outside by fixedly putting the upper cover on the outside of a heat dissipation member to improve the heat dissipation efficiency and the life span of the lamp. The circle type LED lighting flood lamp using a nano spreader includes LEDs, an LED mounting substrate on which the LEDs are mounted, a nano spreader having one side that is in contact with the LED mounting substrate and the other side that is extended for a specified length to form extension parts, an upper cover having inner heat dissipation pins that are in contact with the extension parts of the nano spreader, an upper cap fixed to an upper end of the upper cover, a lower heat dissipation member inserted into the inside of the upper cover and having an inner surface that is in contact with the extension parts of the nano spreader and an outer surface that is in contact with an inner surface of the upper cover, and a lower lens fixed to a lower part of the lower heat dissipation member.
