本文通过对德国家庭进行的具有全国代表性的大型调查，量化了从白炽灯（ILs）或卤素灯泡转向更节能的紧凑型荧光灯（cfl）或发光二极管（led）的直接反弹效应。直接反弹效应是衡量能源需求的弹性照明相对于节能灯具的变化。特别是，反弹效应分解为灯光度和燃烧时间的变化。对于普通灯泡，相关的总直接反弹效应估计约为6%。这种反弹效应的大部分（约60%）来自灯泡亮度的增加。对于最频繁的（模态）灯泡开关，即更换客厅或餐厅的主灯泡，总直接反弹效应略低于3%，其中约60%可归因于燃烧时间的增加。球的平均和模态差异表明，反弹效应的大小可能随着初始球的使用强度而减小。直接回弹的大小以及光度变化和燃烧时间的相对贡献也因初始灯泡类型和更换灯泡类型而异。
This paper quantifies the direct rebound effects associated with the switch from incandescent lamps (ILs) or halogen bulbs to more energy efficient compact fluorescent lamps (CFLs) or light emitting diodes (LEDs) using a large nationally representative survey of German households. The direct rebound effect is measured as the elasticity of energy demand for lighting with respect to changes in energy efficient lamps. In particular, the rebound effect is decomposed into changes in lamp luminosity and burn time. For the average bulb, the associated total direct rebound effect is estimated at about 6%. The larger part (around 60%) of this rebound effect results from increases in bulb luminosity. For the most frequent (modal) bulb switch, i.e. the replacement of the main bulb in the living or dining room, the total direct rebound effect is just below 3%, with around 60% attributable to an increase in burn time. Average and modal bulb differences suggest that the magnitude of the rebound effect may decrease with intensity of initial bulb use. The magnitude of the direct rebound and the relative contributions of changes in luminosity and burn time also differ by initial bulb type and by replacement bulb type.
