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.

A 3-dimension facet light-emitting source device including a transparent container, an anode plate, a cathode plate, a plurality of transparent plates and a low-pressure gas layer is provided. The transparent container has a sealed space. The transparent plates are disposed between the anode plate and the cathode plate, and have a fluorescent layer thereon respectively. The lower pressure gas layer is filled in the sealed space to induce electrons emitting from the cathode plate, and the electrons fly in a direction parallel to the transparent plates and hit each fluorescent layer to emit light, so as to form a set of 3-dimension facet patterns.
