the attenuation problem of laser head has a long history, and there is no good solution at present. Moreover, in the smart car competition, the laser head is not loaded with constant continuous voltage, so the attenuation speed is faster than normal use. We can only extend its normal service life as much as possible without completely avoiding attenuation. Therefore, we strongly recommend that you use the laser head pin connection method we advocate (what we need to suggest here is, do not completely copy all kinds of circuit diagrams obtained through various ways. Each team should appropriately increase or decrease the current limiting electronic resistance according to its own actual situation and experience)!

Use pay attention to matters

1. since the laser is a polar diode, the polarity cannot be reversed, and the power supply voltage is constant DC 2.5-3.1V (the voltage after modulation by the modulation tube is not constant, according to our circuit connection method, the voltage at both ends of the laser head measured by voltmeter is about 0.7V. Therefore, 2.5-V refers to the voltage displayed by the oscilloscope rather than the voltage measured by the voltmeter during measurement). Please use 3V for long-term use, and the current cannot exceed 25mA!;
2. due to the special working principle of the laser transmitter, try to avoid human body contact and objects with static electricity contact the laser tube to avoid electrostatic burning.
3. With the rise of temperature, the laser emission tube will have phenomena such as decreasing luminous efficiency or even not working; Generally, hot raw glue welding will not damage the laser, but avoid overheating of welding and overheating for a long time.
4. Summarizing the above precautions, the solution is: Wash your hands before welding to release the static electricity of human body; The soldering iron should be energized first, and the power supply should be removed during welding. If it is fixed, try to use 502 glue or AB glue, check the polarity and voltage before power-on, and adopt the test touch method to ensure the safe use of laser.
