group aining building for review on buildings and so on. key buildings include the west side of air china hotel, land and resources bureau, china's water policy, the people's bank, the inland revenue department, environmental protection agency, water south police station, lake power company, the county hospital, the financial bureau, the high-speed affic police building, denon ading company, the people court, the irs and so on. set of adminisative, cultural, sports, commercial, cultural and other functions into one, as the show will be music and the image of a window point of the county's economic exchanges, but also the focus of planning in this light. . lighting thematic orientation: embodied elegance, lively, pleasant to the overall theme of the main cold light source, the main building wall with flood lighting, top of the low color temperature warm light with light physical part of the wall sucture within the characteristics of light for the consuction lord.
neon sign2, led modules to improve well-known measurement methods, led light, elecical characteristics and parameters of its work when the junction temperature is closely related to the same led products, will not cause the junction temperature of the clear differences in these parameters, which also caused the same an led light, color, elecical parameter measurement results was inconsistent, so the measurement of the optical parameters of the first led should be considered in setting the conditions for the work to carry out a junction temperature. in addition, led technology for packaging, materials and other differences, the claimed maximum operating junction temperature is significantly different, in order to ensure a highly efficient led lighting products, the characteristics of long life, led junction temperature of the actual work should be significantly lower than the maximum operating junction temperature .
writing boardthe pulse width 0.56ms, interval 0.565ms, 1.125ms period, said the combination of binary "0" to pulse width 0.56ms, interval 1.69ms, said the combination of cycle 2.25ms "1." pulse signals are modulated in the accounting space ratio of 1 / 3, the carrier frequency of 38khz and then sent. binary parameters "0" and "1" shown in figure 4. demodulated binary signal from the infrared infrared receiver integrated hs0038 to complete. for the receiver, when no infrared pulse data output signal out when the hs0038-ended output high, when a high pulse infrared signal out-ended output is low, so the output signal level and ansmitter just the opposite. this is in the software design should be noted.
