• Feasa LED测试仪的使用Using the Feasa LED Tter(yser)：

 目前LED检测的方法有分析仪和人工目测，仪器配置多、成本高、，对使用者的要求高，主要面对大型企业的研发部门；一些技术实力和资金有限的小型企业普遍采用人工目测的方法，其缺点显而易见，对检测人员的经验有所要求，工作量大，容易视觉疲劳，导致漏检和误判，终导致效率低下。

Feasa LED测试仪可以充分发挥在PCBA组装制程控制中的作用，在组装有LED的PCBA生产过程中，通过对标准品PCBA的LED的颜色和亮度进行学习，读取一个相对值作为标准值，并设置标准值的上下限，然后批量读取待测PCBA上的LED相对值与标准值进行比对，从而判断良品和不良品，地测试测，结合I在线测试和功能测试，不用增加测试工位，了效率，快速、全自动化，避免人为漏判。

Feasa LED测试仪是一个测量系统，能够实现快速和自动测试LED的颜色和亮度。每个LED分析仪能同时测量多达20个通道的不同颜色和强度的LED光源。从光纤 采集光源，进行测量和分析。该装置是专为LED和液晶显示器等设计的自动测试装置。

The Feasa LED yser is a measurement system that allows fast and automatic tting of both the color and intensity (Brightns) of Light Emitting Diod (LEDs). tting of both the color and intensity (Brightns) of Light Emitting Diod (LEDs). Each LED yzer can simultaneously measure up to 20 different light sourc for Color and Intensity. Light from the LEDs is colleed by Plastic Optical Fibers (POF) and carried to the LED yzer board for measurement and ysis. The unit has been digned for tting LED's and other lighting devic such as LCD Displays automatically.

该分析结果可以通过并行接口、RS232串行接口或U接口读取，读回所需信息的时间小于1.5秒，这使得它适合集成在自动测试设备（ATE）。对于过20个 通道的LED测量，可以串联多个LED测试仪同时使用。

The rult of the ysis can be read out via the parallel interface, RS232 serial interface or U. The time needed to read back the information is ls than 1.5 seconds, which mak it very suitable to integrate in automatic tt equipment (ATE). For applications with more than 20 LEDs multiple LED ysers can be used together.

LED测试仪可用于功能测试 系统和I在线测试系统的应用程序。测试的应用范围从LED的显示器和移动电话，汽车照明等，在电子行业生产线检查系统中也被应用于替代人工视觉。

The LED yser can be used for both Funional tting and for In-Circuit tt applications. The applications range from tting LED’s and Displays in mobile phon, lighting systems in the automobile industry or position checking of eleronics components in produion lin. It has also been implemented in artificial vision applications.

Feasa LED测试仪是一个大，高度，高重复性，适应，使用方便，快速，全自动化LED颜色和强度测量 仪器，广泛应用于PCB业界和测试设备。

In summary the Feasa LED yser is a powerful, highly accurate, highly repeatable, adaptable, easy to use, fast and fully automated LED color and intensity measurement sensor which has found many applications in the PCB industry on both funional and In-Circuit tt equipment.

• Feasa LED测试仪的参数SPECIFICATIONS

INTERFAC接口:

注：

1、U接口可以直接为LED测试仪供电，不需要额外提供外部电源。波特率达460800。

Uoffers a very simple interface to the LED yser with requirement for an additional power supply. Very high baud rat, up to 460800 baud, are available.

2、RS232串口波特率达115200，需要额外提供外部电源。

TheRS232 Serial Portis easy to use with a max baud rate of 115200. It requir the use of an external power supply.
 The 20pin I Port can be used in either Frequency Out or Synchrous Serial Mode.

3、Frequency Out应用于RS232串口不能访问的情况下，用三个频率表示LED的颜色与亮度。

The Frequency Out protocol can be used where accs to an RS232 Serial Port is t available. Three frequenci are used to reprent the Color and Intensity of the LEDs.

4、Synchrous Serial应用于当使用者的资源受限或者没有其它端口可供选择的情况下。

The Synchrous Serial protocol is suitable when tter rourc are limited or other options are available. 

5、Daisy Chain接口可以将多个LED测试仪使用菊花链连接器连接在一起，要一个RS232串行端口或U端口连接多达30个LED测试仪。

Multiple LED ysers can be conneed together using the Daisy Chain Conneors. Only one RS232 Serial Port or U Port is required to conne up to 30 LED ysers.

TT TIME测试时间:

测试速度取决于LED的亮度，亮度高的测试时间短，亮度低的测试时间长。根据LED的光强（亮度）同时测试20个LED的时间快达1.2ms。从光纤中读取数据，平均每根光纤大约5ms。见下面举例：

The speed of the tt is dependent on the intensity of the LEDs being tted, i.e. Bright LEDs have a shorter Tt Time, Dimmer LEDs have a longer Tt Time. The capture (measurement) of up to 20 LEDs is done in parallel and can be achieved in tim as fast as 1.2ms depending on the Intensity (Brightns). The data is read back from each fiber sequentially and tak approximately 5ms per fiber, for example:

Ultra High Brigh LEDs:

1 LED    ---捕捉时间2ms加上数据读取时间5ms，总共7ms。

1 LED    ---Capture Time is 2ms and Read Back is 5ms, Total 7ms

20LED's---捕捉时间2ms加上数据读取时间100ms，总共102ms。

20LED's---Capture Time is 2ms and Read Back is 100ms, Total 102ms

Dim LEDs:

1 LED    ---捕捉时间650ms加上数据读取时间5ms，总共655ms。

1 LED    ---Capture Time is 650ms and Read Back is 5ms, Total 655ms

20LED's---捕捉时间650ms加上数据读取时间100ms，总共750ms。

20LED's---Capture Time is 650ms and Read Back is 100ms, Total 750ms

U、RS232端口测试捕捉时间   U / RS232 SERIAL PORT – TT CAPTURE TIM

每根光纤读取时间一般保持在5ms时间左右。

The Read Back Time per fiber is always approximately 5ms.

I捕捉时间与U/RS232串口相同。但是，数据读取时间取决于于被测量的频率。使用安捷伦i3070的读取的时间大约是400ms至700ms。

For I the Capture Tim are the same as U/RS232 Serial Port. However, the Read Back Tim are dependent on the frequenci being measured. Using an Agilent i3070 the Read Back Tim are 400ms to 700ms approximately.
