机器视觉检测设备LED光源的特点

目前机器视觉检测设备的光源主要采用LED,也称发光二极管,由于其形状自由度高,使用寿命长、响应速度快、单色性好、颜色多样、综合性价比高等特点在行业内广泛应用,那么机器视觉检测设备LED光源的特点有哪些呢,综合下来包含一下几点。
At present, the light source of machine vision testing equipment mainly uses led, also known as light-emitting diode, because of its high freedom of shape, long service life, fast response speed, good monochrome, color diversity, comprehensive cost-effective characteristics in the industry widely used, then machine vision testing equipment LED light source characteristics of what? Combine to include a few points.

形状自由度,一个LED光源是由许多单个LED组合而成的,因而跟其他光源相比,可做成更多的形状,更容易针对用户的情况,设计光源的形状和尺寸。

Shape freedom, an LED light source is a combination of many individual LEDs, so compared with other light sources, can be made into more shapes, more easily for the user's situation, design the shape and size of the light source.

使用寿命长,为了使图像处理单元得到精确的,重复性好的测量结果,照明系统必须保证相当长的时间内能够提供稳定的图像输入。LED光源在连续工作10,000到30,000小时后,亮度衰减,但远比其他型式的光源效果好。此外,用控制系统使其间断工作,可抑制发光管发热,寿命也将延长一倍。
Long service life, in order for the image Processing unit to obtain accurate, reproducible measurement results, the lighting system must ensure a considerable amount of time to provide stable image input. LED light source after 10,000 to 30,000 hours of continuous operation, brightness attenuation, but far better than other types of light source effect. In addition, the use of control system to make it discontinuous work, can inhibit the heat of the luminescent tube, life will be extended one times.

响应速度快,LED发光管响应时间很短,响应时间的真正意义是能按要求保证多个光源之间或一个光源不同区域之间的工作切换,采用专用控制器给LED光源供电时,达到最大照度的时间小于10s
Fast response speed, LED luminescent tube response time is very short, the real meaning of response time is to ensure that the requirements of multiple light sources or a different area of a light source between the work switch, the use of dedicated controller to the LED light source power, to achieve the maximum illumination time is less than 10s

颜色多样,除了光源的形状以外,得到稳定图像输入的另一方面就是选择光源的颜色。甚至相同形状的光源,由于颜色的不同得到的图像也会有很大的差别。实际上,如何利用光源颜色的技术特性得到最佳对比度的图像效果一直是光源开发的主要方向。
Color diversity, in addition to the shape of the light source, to obtain stable image input on the other hand is to choose the color of the light source. Even the same shape of the light source, due to the different colors of the image will also be a great difference. In fact, how to use the technical characteristics of light source color to obtain the best contrast image effect has been the main direction of light source development.

综合性运营成本低,选用低廉而性能没有保证的产品,初次投资的节省很快会被日常的维护、维修费用抵消。其他光源不仅耗电是LED光源的2-10倍,而且几乎每月就要更换,浪费了维修工程师许多宝贵的时间。而且投入使用的光源越多,在器件更换和人工方面的花费就越大,因此选用寿命长的LED光源从长远看是很经济的。
The savings from the initial investment will soon be offset by daily maintenance and maintenance costs, with low comprehensive operating costs and inexpensive and non-guaranteed performance products. Other light sources not only consume 2-10 times as much power as LED light sources, but also change almost every month, wasting a lot of valuable time from maintenance engineers. And the more light sources put into use, the greater the cost of device replacement and labor, so the choice of long life LED light source in the long run is very economical.
