高棚灯（工矿灯）和低架灯的区别
高棚和低湾灯具都是较低安装高度的理想选择，如仓库，健身房，装配区，食品加工厂和机库。标准高架或低架灯具通常使用HID（高强度放电）灯泡，这是一种特别类型的照明，比大多数其他光源强得多。金卤灯物最常用于室内应用，因为它发出蓝白色亮光，比HPS（高压纳气灯）更让眼睛舒服。

低架灯具应用于灯具底部距离地面不到20英尺（6米左右）的地方。低架灯具直径通常为22 - 28英寸（60公分左右），以便均匀地传播光。低架HID灯具具有包裹和减少眩光的反光罩，它们的广泛分布改善了垂直照明，并允许间隔多达两个或更多此外，当需要高垂直照度时，它们可以安装高达25英尺（7米左右），荧光灯具也适用于低棚灯照明，因为它们具有优异的均匀性和与HID相比相对较低的流明封装。

高架照明灯具应用于灯具底部高于地面20英尺（6米左右）以上的区域。典型的高架灯具具有15-18英寸（40公分左右）开口反光罩，允许更加集中的光束扩散，并具有明显的向下分量。通常需要高功率的荧光灯和HID源以便更好地照亮空间。

High Bay & Low Bay Lighting Fixtures
High Bay and Low Bay light fixtures are perfect for low mount applications such as warehouses, gyms, assembly areas, food processing plants and hangars. Standard high bay or low bay fixtures normally use HID (High Intensity Discharge) bulbs which is a special type of lighting that is much more intense than most other light sources. Metal Halide is most commonly used for indoor application since it emits a bluish white bright light that is much more pleasant to the eyes than HPS.

Low bay fixtures should be used in areas where the bottom of the luminaire is less than 20 feet above the floor. Low bay fixtures are usually 22 - 28" in diameter in order to spread the light evenly. Low bay HID lighting fixtures have optical refractors that cover the lamp and reduce glare. Their widespread distribution improves vertical illumination and permits spacings as much as two or more times their mounting height. In addition, they can be mounted up to 25' when high vertical illuminance is required. Fluorescent fixtures are also good for low bay lighting due to their excellent uniformity and relatively low lumen package compared to HID.

High bay lighting fixtures should be used in areas where the bottom of the light fixture is more than 20 feet above the floor. Typical high bay fixtures have a 15 - 18" open reflector allowing for a more concentrated beam spread with a prominent downward component. High wattage sources in fluorescent and HID are usually required in order to properly illuminate the space.


关于金卤灯简介：
名称：金属卤化物灯，简称金卤灯，英文名为Metal Halide Lamp

金卤灯是交流电源工作的，在汞和稀有金属的卤化物混合蒸气中产生电弧放电发光的放电灯，金属卤化物灯是在高压汞灯基础上添加各种金属卤化物制成的第三代光源。照明采用钪钠型金属卤化物灯，金卤灯具有发光效率高、显色性能好、寿命长等特点，是一种接近日光色的节能新光源，广泛应用于体育场馆、展览中心、大型商场、工业厂房、街道广场、车站、码头等场所的室内照明。

优缺点：
金属卤化物灯的最大优点是发光效率特别高，光效高达80～120Lm/W。由于金属卤化物灯的光谱是在连续光谱的基础上迭加了密集的线状光谱，故显色指数特别高，即彩色还原性特别好，Ra可达90。另外，金属卤化物灯的色温高，可达5000～6000K，专用投影机灯可达7000～20000K。在同等亮度条件下，色温越高，人眼感觉越亮。由于材料、工艺的限制，目前国产金属卤化物灯寿命在8000小时。

High bay light,是工矿灯，我们大家都知道!
客户不太懂，他想买低功率的工矿灯，于是Low bay light问世了。。。大家想想看我这个思路对不对
