Utilization of simulated annealing method for optical design of a thin rectangular small-size edge-type hollow-cavity LED luminaire
In this paper, we present the simulation results using simulated annealing method in the preliminary optical design for the hollow cavity of a thin rectangular small-size edge-type hollow-cavity LED luminaire. The simulation results demonstrated its feasibility of commercial use with both illuminance uniformity and light extraction efficiency of above 80% on the emission surface of its hollow cavity.
An illumination apparatus
The present invention discloses a lighting apparatus comprising a lamp vessel (1), located in the lamp tube (1) across the end cap (2), provided in the lamp light assembly (3) in (1) and with to the lighting assembly (3) of the drive (6), characterized by: further comprising an antenna for wireless communication (4) and the wireless communication circuit (5), said antenna (4) disposed in the end cap within the cap (2), the wireless communication circuit (5) connected to a side of the lamp tube (1) or at least partially and the wireless communication circuit (5) (2) is provided to the said drive (6) and the other side is connected to the antenna (4). Maintaining the shape of conventional lighting apparatus lighting apparatus according to the present invention, wireless communication can be performed well and higher brightness.
Symptomatic Trans-sexualism
A 24-year-old male schizophrenic had a delusion that he was female and had lived his life as a woman for almost two years. Unlike the only other reported case, his ‘symptomatic transsexualism’ responded to the effective treatment of his schizophrenia.
