How to identify the quality of integrated ceiling LED panel light
First, look at the overall "power factor of the lighting": a low power factor means that the power supply of the drive system we use, and the circuit structure design is not good, which will greatly reduce the service life of the lighting. Generally, the power factor of ceiling LED panel lights exported through enterprise development requires training students to reach 0.85 or more, and the power factor is lower than 0.5. Such a problem belongs to their own unqualified and cultural products.
Secondly, look at "Lighting Design Heat Dissipation Technical Conditions - Materials and Structure": LED panel light lighting heat dissipation is also very important, the same lighting power factor and the same lamp bead quality, if there is no heat dissipation environmental conditions, the development is not good, under high temperature When working, the light will be attenuated greatly, and the lighting life will be reduced. Generally speaking, copper conducts heat better than aluminum, and aluminum conducts heat better than pc.
Third, look at the "quality of lamp beads": The quality of lamp beads depends on chip quality and packaging technology, and chip quality determines the brightness and light decay of lamp beads. A good lamp bead not only regulates the high luminous flux, but also has a small light decay.
Fourth, look at the use of lighting power: the life of the power supply is much shorter than the rest of the lighting, and the life of the power supply affects the overall life of the lighting. The theoretical life of the bulb is 5-10w hours, while the life of the power supply is 0.2-3w hours. The design and material selection of the power supply will determine the longevity of the power network.
Five, look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting control brightness, the lower the power consumption cost, the more energy-saving.
Sixth, look at the technical efficiency of power management: The higher the level of power work and learning efficiency, the better, the higher the power consumption of a power control system itself, the greater the output power.
