The Life Of LED Lamp Is Related To Those Factors

- May 11, 2018 -

In general, the four main factors of LED lamp life are:

LED is an electrostatic sensitive element. If the LED lamp is not equipped with anti-static measures, it will burn the LED and cause waste. Of course, the life of the LED lamp is not guaranteed.

The poor toughness of the copper wire or flexible circuit board of LED lamp will cause the LED lamp to break when bending, which will also affect the life of LED lamp belt.

Power supply, LED lights belt is generally USES the constant voltage power supply (dc switching power supply) power supply, if the output of the power supply is not stable, there is no surge protection, or will the outer net voltage fluctuation voltage and current output is not stable, lead to LED lights work under non standard voltage, may also affect its service life.

Since LED is a constant current element, the constant current effect of LED lamps produced by different manufacturers is different, and of course, the life span is different.

In addition to the heat dissipation of the most common adverse, according to the experiences on the application of LED die light or droop, the cause of the discoloration and caused by chemical pollution in manufacturing process, for the application of the downstream side, except for proper cooling solution, in the process of the assembly of lamps and lanterns, or production process of chemical additives are required to avoid the so-called chemical incompatibilities.

The incompatible volatile organic compounds in LED lighting can quickly damage any manufacturer's LED. This chemical incompatibility is often a local phenomenon occurring at elevated temperatures and in sealed lamps with little or no air flow. After the test of LED sealing factory, some chemicals known to easily affect the normal function of LED are found. It is better to establish a perfect chemical incompatible test evaluation system. With appropriate precautions, design and testing, the effects can be minimized or eliminated.

The most obvious adverse effects of chemical incompatibility are blue, dark blue and white LED, with few observations of red or green leds. Designers should give full consideration to minimize impact between chemicals (mainly LED a Molding plastic optical lenses and used in the electronics assembly and lamps and lanterns of various chemicals) for these items match together may damage the LED light output efficiency, make even with leds, gave birth to a permanent failure phenomena (such as dead light, color, dark, etc.). Because of chemical incompatibility and high LED packaging temperature, the result of LED failure is the same: that is, light flux attenuation and color temperature drift.
