卤素灯的照度管理影响着能耗和照明效果。本文介绍了一种基于HL的光源照度智能控制方法。在照度分析模型和实验工作的基础上，得到了光源功率、照度和光源深度之间的关系，即单个光强和组合光强。计算了不同类型光源的照度均匀性。揭示了两个HL模块间距（DBM）对照度均匀性的影响机理。讨论了单体氢氧化氢和复合氢氧化氢的能量转换效率。通过模型测量结果与人工测量结果的比较，分析了照度分析模型的测量精度。结果表明，基于图像的深度测量方法在高强度条件下效果良好。对于单个HL，离照度中心越远，照度越低。发现功率与照度之间存在良好的相关性，验证了通过调节功率精确改变HL照度的可行性。随着DBM的增大，HL的照度均匀性先增大后减小。在DBM 0.6 m处，HL的照度均匀度最高，达到66.1%。该照度测量方法适用于HL工况，导致模型测量结果与人工测量结果存在相对误差。基于高宝贵度的照度测量，可进一步实现高照度控制。HL的智能控制不仅有利于为地下开采中的人或机器提供适当的照明，而且可以促进能源消耗与自然资源之间的平衡。
Illuminance management of halogen lamp (HL) affects energy consumption and lighting effect. A smart control methodology of illuminance for light sources based on HL was described in this study. Based on the illuminance analysis model and experimental works, the relationship between power, illuminance and depth of light sources, i.e. single HL and combined HLs is obtained. The illuminance uniformity of different types of light source was calculated. The influence mechanism of interval distance between two HL modules (DBM) on illuminance uniformity was revealed. The energy conversion efficiency of single HL and combined HLs was discussed. By comparing the model measured results and the manual measured results, the measurement accuracy of the illuminance analysis model was analyzed. The results show that the image-based depth measuring method works well under the HL condition. For single HL, the farther away from the illuminance center, the lower the illuminance. It is found that there is a good correlation between power and illuminance, which verifies the feasibility of accurately changing HL’s illuminance by adjusting power. With the increase of DBM, the illuminance uniformity of HL increased at first and then decreased. The illuminance uniformity of HL at DBM 0.6 m is the highest, which is 66.1%. The illuminance measurement method is suitable for HL condition, which leads to the relative error between the model measured results and the manual measured results. The illuminance control of HL can be further realized based on high-precious illuminance measurement. Smart control of HL is not only conducive to providing appropriate illuminance for humans or machines in underground mining, but also can promote the balance between energy consumption and natural resources.
