照度标准

Three LEDs biology light sources with different intensity for cell or tissue culture have been developed in the third part of this thesis. A concave lens to expand the beams of light, to focus the rays of light and an array of LEDs being set in the sphere connected with Fresnel lenses are three newly-designed in our systems.

实际测试数据表明：低强度光源输出的辐射照度范围为0.0021—0.9961(W／m~2)，在直径20mm的照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=40，Mean：0.71 W／m~2)；中等强度光源输出的辐射照度范围为0.3579—11.2286(W／m~2)，在直径30mm照射面积内所测辐射照度的标准偏差为0.02W／m~2n=60，Mean：6.37 W／m~2；较高强度光源输出的辐射照度范围为17—110(W／m~2，在直径40mm照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=80，Mean：71.54 W／m~2)。

The best of comprehensive efficiency between natural lighting and heat insulation is Low-E glass, the best performance of natural lighting is clear glass, but performance of heat insulation is bad, the best performance of heat insulation is green semi-reflective glass, average daylight factor is about 1% over, 0.7% of residential standards, but its illuminance is not suitable about 200 Lux.

平均昼光率与室内玻璃表面温度标准差之比值的综合效能评估中，Low-E玻璃为采光与隔热综合效能最优异之材质，而清玻璃为采光效能最优异之玻璃材质，但清玻璃隔热效能不佳，绿色半反射玻璃的隔热效果最好，而采光方面的昼光率平均为1%，采光虽然还符合住宅的昼光率标准0.7%，但照度普遍不佳，平均室内照度约200 照度。

This paper mainly studies the illuminance level of the road lighting in campus areas and recommends the lighting standards.

本文主要对影响高等学校校园道路照明质量的照度水平进行了定量地评价，建议了高等学校校园道路照明的照明标准。

The researchers found that luminance exceeded recommended levels in 88 per cent of the classrooms they investigated.

研究者发现，在他们的调查中，有百分之八十八的教室灯光亮度过高，超过了推荐的照度标准。

The irradiance on the earth synchronous orbit and median orbit in the standard atmosphere was computed.

对地球同步静止轨道、中轨道卫星标准大气下的核爆光辐射探测器的接收照度进行了计算，得出了理想状态下探测器的动态范围及灵敏度。
