Teach you choose integrated ceiling LED Panel Light

Principle 1: look at the overall lighting power factor

Power factor is low, indicating that the drive power supply circuits for use poorly designed and thus greatly reduce the life of lighting. How to detect? - Power factor meter general export LED panel light required to achieve a power factor above 0.85. If the power factor is less than 0.5, the product is defective. Not only life is short, and power consumption than ordinary energy-saving lamps is about doubled. Therefore, LED panel lights must be equipped with high-quality high-efficiency drive power. If there is no power factor meter for monitoring LED lighting power factor of consumers, it can be used to monitor the ammeter. Current, the greater the power, the more expensive electricity. Current instability, the shorter the life of the lighting.

Principle 2: Look lighting conditions --- cooling structures, materials,

LED lighting heat dissipation is critical, the same lighting and power factor with quality lamp beads, heat dissipation is not good if the lamp beads at high temperatures, light will be large, thereby reducing the service life. Heat sink material according to the effect from the high points in the end to copper, aluminum, PC, radiating materials currently on the market is the main choice of aluminum, is currently the best aluminum inserts, followed by aluminum car, the worst is cast aluminum, compared , the best cooling effect aluminum inserts.

Principle 3: Look lighting drive

The power of life relative to the rest of the lighting is much shorter life span of the lighting power of the overall life expectancy. Theoretically, lamp beads life 5-10 million hours of battery life at 0.2 to 3 million hours. Therefore, power supply design and material selection will directly affect the life of the power supply. Choose the appearance of an aluminum alloy material is recommended for the purchase of power-driven. Because aluminum than plastic heat, and in the long-distance transport can protect the internal parts are not damaged or loose, thus a lower failure rate.

Principle 4: see lamp beads quality

Quality lamp beads determines the quality and chip packaging technology. And in turn determines the quality of chip brightness and lamp beads light fades. Generally good lamp beads only bright lighting, and the light fades is small.

Principle 5: see the light effect

Equal power lamp beads, the higher the luminous efficiency, higher brightness; the same illumination, power consumption smaller, more energy-efficient.
