How to Determine the Quality of LED Beads.p5 outdoor rental led display

　　Looking at the overall "power factor of lighting fixtures": low power factor indicates that the poor design of the driving power supply and circuit used will greatly reduce the lifespan of the lighting fixtures. Low power factor means that even with good use of the lamp beads, the lifespan of the lighting fixtures will not be long. Looking at "Luminaire Heat Dissipation Conditions - Information, Structure": LED lamps are also very important for heat dissipation. Luminaires with the same power factor and lamps of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures, and the light attenuation will be large, and the lifespan of the lamp will be reduced.

　　Look at "Lamp bead quality": Lamp bead quality is determined by chip quality and packaging technology. Looking at the driving power supply used in the lamp, the lifespan of the power supply is much shorter compared to other parts of the lamp. The lifespan of the power supply affects the overall lifespan of the lamp, with the theoretical lifespan of the lamp bead ranging from 50000 to 100000 hours and the lifespan of the power supply ranging from 20000 to 30000 hours. The design and selection of the power supply will determine the lifespan of the power supply.
