The lifespan of a lamp depends on its power factor, heat dissipation conditions, and driving power supply. Take a look at the overall 'power factor of the lamp'. The low power factor indicates that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp. With low power factor, the lifespan of the lamp will not be long even if the lamp beads are used well. Secondly, look at "Heat dissipation conditions of lighting fixtures - materials and structures". Heat dissipation of LED lamps is also very important. If the heat dissipation conditions are not good for lamps with the same power factor and lamp beads of the same quality, the lamp beads will work at high temperatures, resulting in significant light attenuation and reduced lamp life. Looking at the driving power supply used by 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. The theoretical lifespan of the lamp bead is between 50000 and 100000 hours, while the lifespan of the power supply is between 20000 and 30000 hours. The design and material selection of the power supply will determine the lifespan of the power supply.
