| 摘要： | The present study was designed to update the market-weighed database of current U.S. low-beam headlamps for model year 2004. The main features of this study were as follows: The lamps to be photo metered were directly purchased from vehicle dealerships, thus avoiding the potential problem of self-selection with donated lamps; The selected lamps were designed for use on 39%of all passenger vehicles currently being sold in the U.S.; and The obtained photometric data were weighted by the current sales figures for the respective vehicle models. |
