Abstract:
A light-emitting diode road lamp structure includes a seat body and a plurality of tube bodies. The seat body includes an accommodation space to accommodate a circuit unit. The tube bodies are juxtaposedly connected to an outside of the seat body, a plurality of light-emitting (LED) units accommodated in the tube bodies are electrically connected to the circuit unit, and an interspace is formed between each of the tube bodies and the tube body abutted therewith, thereby providing the road lamp with a better heat-dissipation efficiency by the air flow passing through the interspace, maintaining the luminous efficiency of the LED units, and extending the life span of the LED units.
Abstract:
Disclosed are a semiconductor nanowire solid state optical device and a control method thereof. The device comprises a nanowire, a first electrode, a second electrode, an electrical circuit and a mechanical micro device. The nanowire has a first end and a second end. The first electrode is coupled to the first end. The second electrode is coupled to the second end. The electrical circuit is coupled to the first electrode and the second electrode. The mechanical micro device is conjuncted with the nanowire for applying an external force to the nanowire to form highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) in the nanowire. The HOMO and LUMO are employed as an n-type semiconductor and a p-type semiconductor, respectively. The nanowire is a semiconductor when an external force is applied thereto.
