LED Flexi

 3. Precautions

  MR16

        (1) check if dim glow, indicating that the device has been aging, the luminous efficiency is too low. If the display of the pen incomplete, indicating that digital tube has been partially damaged.

  T8 Tube

        (2) For the model is unknown, nor pin arrangement diagram of LED digital tubes, with a digital multimeter h from the block to be completed by the following test: ① determine the digital control structure (common cathode or common anode); ② recognition tube feet; ③ Check the full light strokes. Advance an electrode can be assumed as a public pole, then the strokes emit light or not be verified. When the pen segment electrode pole reversal, or public misjudgment, this amount can not shine paragraph.

Digital LED tube (LED) is a semiconductor light emitting device, the basic unit is a light emitting diode. Digital tube divided by the number of segments and eight seven-segment digital tube digital tube, eight digital tube more than a seven-segment digital tube light emitting diode unit (one more decimal point); press to show the number "8" can be divided into 1, 2, 4, and so digital pipe; press emitting diode unit connection into common anode and common cathode digital tube digital tube.
