Main parameters of LED lighting products: luminous flux (unit: LM), color rendering index (unit: Ra), color temperature (unit: K), power factor (unit: PF), heat dissipation capacity

Luminous flux: mainly refers to the brightness of the product. Lamps emit light energy by consuming electrical energy. The greater the luminous flux, the more light energy is emitted. Therefore, it is an indicator of the luminous ability of the light source. When the power consumption of the two lamps is the same, the greater the luminous flux, the better the lamp. General LED lamps can reach 90-110LM/W, and good lamps can even reach 120-150LM/W. (traditional incandescent lamps 10-15LM/W; energy-saving lamps 30-65LM/W)

Color rendering index: Color rendering index refers to the ability to reproduce a color. The higher the color rendering index, the more positive the color. By comparing the apparent color of an object with a reference or benchmark light source (incandescent lamp) of the same color temperature. To restore the percentage of the original color of the object, it is necessary to use a light source with a high color rendering index to correctly represent the original color of the material. The value is close to 100, and the color rendering is the best. Incandescent lamps 97-100, LED lamps 85-12.

Color temperature: refers to the color of light. The higher the color temperature, the bluer the light, the lower the color temperature, the redder the light. is the sunlight as the reference standard. There are 3 kinds of conventional color temperature: warm light (yellow light) 2700-3500K representative symbol: RN; neutral white 4300-5000K representative symbol: RZ white light (cool white) 5800-6500K; representative symbol: RR.

Power factor: and power compensation of power conversion light source. The size of the power factor depends on the power factor of the driving power supply. The larger the power factor, the better the conversion efficiency

Heat dissipation capacity: The heat dissipation capacity of LED products directly affects the service life and light decay rate of the product. Products with higher power and products with longer lighting time have higher requirements for heat dissipation. Conventional LED products will use metal casings with built-in or external heat sinks to dissipate heat from lamps.
