optical tubes 中文意思是什麼
optical tubes
解釋
光學鏡筒-
The dome - top, plane - top ; large - reflective bowl, small - reflective bowl ; wild - degree bowl, narrow - degree bowl ; deep assembling, middle assembling and low assembling led tubes were simulated and experimentally measured for comparison. some conclusions can be drawn that the simulation results fit the experimentation results well in the light distribution. this testified that monte carlo method is one of the effective tools for led light ' s optical design
根據驗證和分析比較不同led光學結構的需要，製作了有代表性的19種管型的樣管，分別對其模擬模擬輸出配光曲線圖和測試，在模擬光子數設定為10000000個， 1000次反射無出射視為光子被吸收等參數條件下，得到模擬和測試所得配光曲線在一定的誤差范圍內是相同的。 -
For the measurement of lens parameters, traditional method is based on pure mechanical and optical system, or just simply assisted by nixie tubes. this brings many inconveniences in adjusting and measuring, and it can hardly ensure the measurement precision and efficiency
對于光學透鏡參數的測量，傳統的手段是使用純機械和光學器件構成的系統，或者輔以簡單的數碼管顯示，調試、測量過程較為繁瑣，精度和效率都不能得到很好的保證。 -
