LED light-emitting diode overcurrent prevention measures

LED light-emitting diode overcurrent prevention measures
 
1, can not have over-current or over-voltage during use.
 
2. In order to use the diode under stable conditions, it should be connected with the protection resistor in series. The resistance value is determined according to the provided limit voltage or current limit. It is recommended to use the IF range 3-18mA.
 
3, the instantaneous pulse will destroy its internal fixed connection, so the circuit must be carefully designed so that when the circuit is opened and closed, the device will not be subjected to overvoltage (current) impact.
 
Brightness requirements
 
1. For uniform brightness, use the same current for the same batch.
 
2. Under the rated current and voltage conditions, the brightness increases with the increase of the current intensity.
 
3. Uniform brightness is more likely to be obtained at IF=20mA.
 
4. When visually inspecting, keep the eye LED to a distance of 30cm.
 
Note: Pure blue, pure green, violet. The white light tube should be well-prevented in the process of transportation, IQC, production and use.
