What will affect the service life of LED engineering light band

The poor toughness of copper wire or flexible printed circuit board of LED engineering light strip leads to the fracture of LED engineering light strip when it is bent, which also affects the service life of LED engineering light strip. Power factor, LED technology lamp is usually powered by constant voltage power supply (DC switching power supply). If the power supply output is unstable or without overvoltage protection, if the external power supply voltage fluctuates, it will output unstable voltage and current.

If the size of the radiator is to be determined, the same luminous efficiency should be used for calculation. Generally speaking, at present, the optical efficiency of 100 LM / W, the actual electro-optic efficiency (that is, the efficiency of electric energy converting into light energy) is only about 30%, that is to say, only 30% of the electric energy is converted into light energy, and the remaining 70% of the electric energy is converted into heat energy, which must be distributed through the radiator. For 1W high-voltage led and ordinary low-voltage led with the same luminous efficiency, the part of heat energy is 0.7W, which must be cooled by cooler. Therefore, under the same input power and driving power efficiency, there is no difference in the radiator size required for the high-voltage led.

The LED strip usually has a high voltage of 220 volts, so it is covered with thick flame retardant rubber. Wires and circuit boards are usually made of copper. Led beads confirm that there is no lead. For safety reasons, the service life of LED high-voltage lamps must not be inferior, because they are cheap, which may have security risks! Of course, you will find that high quality products and reasonable prices are not without problems, but this opportunity is not everywhere! Since the high-quality LED technology entered the market, it has a broad market.
