| 20090128004 | LIGHT-EMITTING DEVICE - A light-emitting device comprises a substrate, at least one light-emitting structure configured to emit light beams and positioned on the substrate, and a ring-shaped photonic crystal structure positioned in the light-emitting structure. The ring-shaped photonic crystal structure includes a plurality of pillars positioned in the light-emitting structure and a plurality of ring-shaped openings surrounding the pillars. The distance between the ring-shaped openings is preferably between 0.2λ and 10λ, and λ represents the wavelength of the light beam. | 05-21-2009 |
| 20090316412 | LAMP APPARATUSES - A lamp apparatus include a lamp body, at least an alternating current light-emitting diode and a plug. The alternating current light-emitting diode is disposed on a lamp body. The plug is electrically connected to the alternating current light-emitting diode. In lamp apparatuses utilizing AC LED, heat generated thereby is almost concentrated on chips. Compared with conventional lamp apparatuses utilizing DC LEDs, heat generated thereby is distributed on chips and outer rectifier. In lamp apparatuses utilizing AC LEDs, heat generated thereby is almost concentrated on chips because AC LEDs operate directly with AC electric power, omitting a rectifier and preventing power loss during operation of power rectification. Therefore, the heat accumulated on the chips of the AC LEDs is enough to be used to evaporate essential oil. In another embodiment, the invention utilizes low-resistance pure water surrounding the AC LED to dissipate its heat. | 12-24-2009 |
