Title
(EN) Method and system for luminance characterization
(ZH) 用于亮度表征的方法和系统
Abstract
(EN)
Methods and corresponding systems for controlling a light fixture include a memory for storing data and software. A multi-tap capacitor has a plurality of tap capacitors integrated into a capacitor housing. A plurality of switches are each coupled to one of the plurality of tap capacitors for selectively coupling the tap capacitors together to produce a variable multi-tap capacitance. A processor is coupled to the memory and the switches to facilitate: detecting a trigger for changing a lumen level output by the light fixture; determining a new lumen level in response to the trigger; determining a capacitance value that corresponds to the new lumen level; and configuring the plurality of switches to produce the multi-tap capacitance that corresponds to the new lumen level. The processor can record data in the memory that represents times of lumen changes and switch settings, which data correlates to power consumption.

包括镇流器线圈和与镇流器线圈串联的多抽头电容器的照明器的亮度表征系统。多抽头电容器具有集成在电容器外壳内的多个抽头电容器。多个开关的每一个与多个抽头电容器之一耦合,以便有选择地将抽头电容器耦合在一起,以产生与多个开关的配置相对应的多抽头电容。灯与多抽头电容器和镇流器线圈串联。光度计被定位成测量灯的光强度并产生流明输出测量结果。存储器用于存储具有多个流明输出测量结果的数据库,多个流明输出测量结果的每一个对应于与多个开关的所有配置相对应的多抽头电容。
