Using solar cell to absorb solar energy and store into battery by DC-DC charger during daytime. When in the night, battery will be discharged to white LED by optical sensor and control circuit. Since the weather maybe cloudy or rainy, there is a spare AC power supply loop consist of transformer, bridge rectifier, filter and voltage regulator to prevent battery undercharge or circuit maintain. When the output current of battery is less than the preset value, the power source of white LED lamp will be switched over to spare AC power supply loop by the comparative and switching circuit.

用太阳能板,在日间吸收太阳光,将能源用DC-DC充电器储存於蓄电池中,夜间时由光感测控制电将蓄电池放电,提供白光LED灯所需的电源,为预防阴雨天蓄电池充电足或电故障维修,将使得灯无法点,另有市电经变压器与整稳压后之预备供电回,於蓄电池输出电低於预设值时,将白光LED灯电源换至市电预备回。

Recombinant plasmid pSVH 7 DNA of avian influenza virus H7 subtype heamagglutinin gene was encapsulated with DC-chol/DOPE liposomes and PC/chol/SA liposomes separately. Two-week old SPF chickens were intramuscularly inoculated with 50 μ g/0.2ml of the liposome entrapped PSVH 7 DNA. Four-weeks later, each chicken was challenged with 0.1ml 〓 AIV . One week after the challenge, the secretion of the cloacas was collected and transfected to chicken embryos to isolate the virus. The virus was isolated from 6/6 of the control group, 1/6 of the naked DNA group, 1/6 of the PC/chol/SA entrapped DNA group and 0/6 of the DC-chol/DOPE liposome entrapped group. The HI antibody titers (log2) of the four groups were 6. 83±0.98, 7. 0±1. 26, 7. 83±1. 17 and 8. 00±0.89 respectively 1-week after challenge, and 8. 5±0.55, 8. 17±0.82, 8. 68±0.45 and 9. 33±0.54 respectively 2-week after challenge. The results showed that inoculation of liposome entrapped DNA significantly enhanced resistance to virosis in animals.
