先来看看这个由上述两个学会，联同14家手电筒或者是照明工具（特指携带用照明工具）的生产商，于2009年制定的 - ANSI/NEMA FL 1-2009 手电基本性能标准 - 的内容全文。我会把当中的重点，翻译成中文，然后供大家讨论的。

然后，我会就这个标准的定义、六大重点：

Definitions 定义
1. Beam Distance 光束射程
2. Peak Beam Intensity 峰值光束强度
3. Run Time 续航时间
4. Light Output 光输出
5. Impact Resistance 耐冲击性

SCOPE 范围

This Standards Publication covers basic performance of hand-held/portable flashlights, spotlights, and headlamps providing directional lighting.

本标准（指ANSI标准），涵盖了提供定向照明的手持/便携式手电筒、聚光灯和头灯的基本性能。

1.2 DEFINITIONS 定义

1.2.1 Beam Distance 光束距离 / 射程

Beam distance is defined as the distance from the device at which the light beam is 0.25 lux (0.25 lux is approximately the equivalent of the light emitted from the full moon “on a clear night in an open field”).

光束距离 / 射程被定义为：从测试样本，到该光束终止照度为0.25勒克斯（Lux）

或者这样理解，射程，是发光体发出来的光，到0.25LUX时距光源的距离

（0.25勒克斯，大约是相当于在一个晴朗的夜晚、开放的领域中，满月发出来的光，让人在该领域中感受到的距离。）

1.2.2 Peak Beam Intensity 峰值光束强度

Peak Beam Intensity is the maximum luminous intensity typically along the central axis of a cone of light.

The value is reported in candela and does not change with distance.

峰值光束强度是最大发光强度（ luminous ）的光，通常是指沿一光锥的中心轴线。

该值是用烛光（candela）来记录的，并不会被距离改变。

1.2.3 Run Time 运行时间 / 续航

Run Time is defined as the duration of time from the initial light output value—defined as 30 seconds after the point the device is first turned on—using fresh batteries, until the light output reaches 10% of the initial value.

运行时间的定义为，使用新的电池，从设备第一次打开的30秒之后算（此定义为最初的光输出值），直到光输出达到刚开始时的光输出值（初始值）的10％的持续时间。

1.2.4 Light Output 光输出

Light Output is the total luminous flux. It is the total quantity of emitted overall light energy as measured by integrating the entire angular output of the portable light source. Light output in this standard is expressed in units of lumens.

光输出是指总光通量（total luminous flux）。它是整体发射光能的总量，是用结合整个便携式（指手电或者是测试物，如头灯）光源角度输出来测量的。

在这一个标准，光输出是以流明（Lumens）为表示单位。

1.2.5 Impact Resistance 耐冲击性

Impact resistance is the degree to which a device resists damage from dropping on a solid surface.

耐冲击性在这个标准中，是指一个抵抗损伤的程度，代表一个设备跌落在坚实的表面时，这个抵御力的强度。

1.2.6 Enclosure Protection Against Water Penetration Ratings 外壳保护 - 防止渗水评级

Based on the ANSI/IEC 60529 standard, the following enclosure ratings for the devices covered by this standard have been defined:

根据 'ANSI/IEC 60529' 标准，下列对设备的防水评级，是受此标准所涵盖的并被定义的

Water Resistant—IPX4—Water splashed against the device from any direction shall have no harmful effects.

防水 - IPX4级 - 装置对来自任何方向的水泼，应无有害影响

Water Proof—IPX7—Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.

防水 - IPX7级 - 在一个一定标准量化的压力和时间下，设备的外壳暂时浸泡在水中，在有一定数量的进水时，不容许对设备造成有害影响。

Submersible—IPX8—Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is continuously immersed in water under conditions which shall be stated by the manufacturer, but which are more severe than for IPX7.

潜水 - IPX8级 - 根据制造商说明的条件（肯定是比IPX7级更为严峻的环境），设备的外壳持续地浸泡在水中，在有一定数量的进水时，不容许对设备造成有害影响。

1.2.7 Hand-Held/Portable 手持式/便携

A hand-held/portable device is small enough to be operated when held in one or both hands (like flashlights, headlamps, spotlights, and bicycle lights) and light enough to be easily carried from place to place.

一个手持式/便携设备，是指足够小到可以在用一到两只手把持住时操作（像手电筒、头灯、射灯及自行车灯），及这设备是可以很容易地携带，由一个地方到另外一个地方。

1.2.8 Spectroradiometer 光谱仪

A spectroradiometer is an instrument capable of dividing light into its constituent wavelengths. For the intent of this standard, a spectroradiometer is used for measuring the total spectral flux and luminous flux of the device under test in the visible spectral range (380 to 790nm).

光谱仪，是一种能够分化光的组成波长的仪器。就本标准的意图，光谱仪是用来测量光谱的总流量和设备的光通量，在可见光的光谱范围(380 to 790nm)下测试。

1.2.9 Light Measuring Device 光测量装置

A light measuring device is a commercially available device that is used to measure the amount of light striking a surface from a given source. Typically, this device is calibrated during manufacture to ensure a certain level of accuracy for the user. Also known as “light meters,” “photometers,” and in some cases can be systems based on CCD cameras or other technologies. The device should be calibrated to the CIE eye response curve.

光测量设备，是一个在商业上应用的终端设备，用于测量一个光源照射到一个表面。通常情况下，此设备是在制造过程中已经被校准，以确保提供给用户一定水平的准确度。此设备也被称为“照度计”，“光度计”，并在某些情况下，可以是CCD相机或其它技术为基础的系统。该设备应以国际照明委员会（CIE）眼响应曲线进行校准。

Surface Light Intensity is defined in this standard as surface illuminance and is measured in units of lux.

表面光强在这个标准的定义，是在一个表面上，以勒克斯（lux）为衡量单位的照度标准。

1.2.11 Integrating Sphere 积分球

For the intent of this standard, an integrating sphere is a measurement device with an entrance port that can accept all the directional light output of the device under test, or can totally enclose the device itself.

The walls of the sphere should be highly diffuse with high reflectivity (>80%) and the spectroradiometer should be shielded from direct view of the device under test by a baffle system.

就本标准的出发点，积分球是一个具有入口端口，在测试时，可以接受测试设备所发出的，定向的光输出，或者可以完全包围测试设备本身的测量设备。

积分球的墙壁，应该是高度漫射及高反射率(>80%)，积分球内的光谱仪，应该由挡板系统屏蔽来自被测设备的直接照射。

2.7.4.3 Submersible 潜水

As described in ANSI/IEC 60529, Section 14.2.8 for IPX8. The duration shall be 4 hours at manufacturer specified depth.

等于在ANSI / IEC 60529，第14.2.8对IPX8所描述的标准。整个过程，将会在生产商声称的防水深度下，维持四个小时。

2.7.5 Passing Criteria 通过标准

2.7.5.1 Water Resistant 防水

All test samples shall function normally immediately after the test and 30 min after the test. Water ingress is allowed as long as the above conditions are met.

所有测试样本，必须在测试完毕的当时和三十分钟后，均功能正常。适量的被水进入是可以容许的，但必须符合以上条件。

2.7.5.2 Water Proof and Submersible 防水及潜水

All test samples shall function normally immediately after the test and 30 min after the test.

所有测试样本，必须在测试完毕的当时和三十分钟后，均功能正常。

The sample passes the water proof and submersible test if there is no ingress of water in any functional area that contains unprotected electrical components (contacts, batteries, PCB, wires) or light sources.

如果在测试设备的功能区，包含没有受保护的电子零部件（接触点、电池、电路板。电线等等）或光源部件，均没有被发现进水，那么测试样品就算是通过防水及潜水测试。

Protection shall provide exclusion of water from the components above.

保护应提供从上面的组件中，排除水的进入和存在。

2.7.6 Enclosure Protection Against Water Penetration Rating 外壳保护 - 防止渗水评级

The submersible rating shall be expressed in meters and rounded down to the nearest whole meter. All five samples must pass the rated depth.

防水评级，应当报与向下调整至最接近的整米的值。所有五个样品，都要通过额定防水深度。

1.2 DEFINITIONS 定义

1.2.1 Beam Distance 光束距离 / 射程

Beam distance is defined as the distance from the device at which the light beam is 0.25 lux (0.25 lux is approximately the equivalent of the light emitted from the full moon “on a clear night in an open field”).

光束距离 / 射程被定义为：从测试样本，到该光束终止照度为0.25勒克斯（Lux）

或者这样理解，射程，是发光体发出来的光，到0.25LUX时距光源的距离

（0.25勒克斯，大约是相当于在一个晴朗的夜晚、开放的领域中，满月发出来的光，让人在该领域中感受到的距离。）
