XPL-V6在1050mA时是480lm,1000lm时的电流是2600mA,TB某家说明了竟然称1000lm时的续航是2.5小时。好像商家 ...
2.4 RUN TIME 续航
2.4.1 Purpose 目的
To provide a procedure to determine the amount of time elapsed (under continuous operation) at which the device’s light output reaches a level when users will commonly replace the batteries.
提供一个程序,以确定续航的时间(在连续工作下),这个时间是指,测试设备的光输出,达到一个水平时,用户通常就会更换电池的时间。
2.4.2 Power Source 电源
All tests are conducted with fresh batteries or fully charged batteries/energy storage devices.
所有的测试,都应该是用新的电池,或经过充满电的电池或者是能源储存装置为电源。
Batteries used for testing and claim substantiation shall be of the same type and/or brand as those offered for sale with the product.
用于测试和声明使用的电池,应是同一类型,和/或与该品牌产品一同出售的电池
If the product is sold without batteries and a beam distance claim is made, a specific battery type and chemistry shall be recommended with the package. The batteries recommended by the manufacturer are to be used for testing.
如果产品销售不包括电池,但有标明续航时间,设备制造商应该在包装上,推荐一个具体类型的电池和电池种类。由制造商建议使用的电池,将被用于测试。
2.4.3 Conditions 测试环境
Tests will be conducted at lab conditions—see clause 2.1.1.
测试将会根据上列第2.1.1的测试环境来进行
Testing should be performed in a dark environment where the ambient conditions are determined to be less than 1 lux in the entire test area prior to taking an actual measurement with a light measuring device.
测试将会在一个全黑的环境下进行,而在测试及使用照度计量度准确的数据之前,该测试环境应被定义为是少于1 lux的一个环境。
If the device offers multiple output levels, the run time will be measured at the maximum level or as otherwise identified.
如果该设备提供多档输出亮度,峰值光束强度将会量度最高档的亮度,或者是说明那一个档位的亮度。
The device shall be securely mounted for testing after the batteries have been inserted.
测试设备应该在放入电池后,牢牢地固定着。
2.4.4 Apparatus 仪器
A timing device and a light measuring device shall be used.
测试将会使用一个计时装置,及一个对光的测量设备(比如照度计)。
2.4.5 Initial and End Point 初始及结束点
The initial reading is taken at 30 s of continuous operation. When using a light measuring device, ensure that the distance from the front surface of the device to the sensor is identical for initial and end point measurements.
开始读数是在测试设备打开后的三十秒内。当使用照度仪的时候,必须确保在初始及结束其间,仪器的探测头和测试设备之间的距离,是一致的。
The light is operated continuously without any off time. (NOTE—If the device has an auto shut off mechanism, the operator must restart the light within 15 s for the test to be valid.)
测试设备必须是连续操作,并没有任何的关闭时间。(注意 - 如果测试设备是有自动关闭的机制,测试操作者必须在15秒内重新启动设备,测试方为有效。)
Periodic light measurements and corresponding time values are recorded, and the end point is reached when the output value reaches 10% of the initial value for each sample.
在测试其间,周期性的光测量和相应的时间值,应该被记录下来;当每个样品,到达最初亮度(初始值)的10%亮度时,定义为到达完结点。
Record run time for each sample.
记录每个测试样本的续航时间。
2.4.6 Final Calculation 最后计算方法
Run Time is the average run time of the 3 samples. A run time less than one hour is reported in minutes; more than 1 hour but less than 10 hours is reported in hours and minutes, rounded to the nearest 15 min.
续航是指三个样本的续航时间的平均值。如果续航是少于一个小时,应该以分钟为记录单位;多于一个小时而少于十个小时的,小时和分钟两个单位都要记录,并四舍五入至最近的15分钟内。
For 10 hours or more, report the run time only in hours. Standard rounding rules apply.
如果是多于十个小时的,使用四舍五入法,只记录“小时”一个单位。
