The 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 capability

  1. Luminous flux: mainly refers to the brightness of the product. The luminaire emits light energy by consuming electric energy. The greater the luminous flux, the more light energy is emitted. Therefore, it is an indicator of the ability of the light source to illuminate. When the power consumption of the two lamps is the same, the larger the luminous flux, the better the lamp. General LED lamps can reach 90-110LM/W in time, and even lamps can reach 120-150LM/W. (Traditional incandescent lamp is 10-15LM/W and energy saving lamp is 30-65LM/W)
  2. 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. A comparison of the appearance color of an object with a reference to the same color temperature or a reference light source (incandescent or painted). Reducing the percentage of the true color of the object, the correct expression of the original color of the material requires the use of a light source with a high color rendering index, the value is close to 100, and the color rendering is best. Incandescent lamp 97-100 , LED lamp 85-12
  3. Color temperature: refers to the color of light, the higher the color temperature, the light blue; the lower the color temperature, the light is reddish. It is based on sunlight. There are three kinds of conventional color temperatures. Warm light (yellow light) 2700-3500K Representative symbol: RN. Neutral white 4300-5000K represents: RZ white light (cold white) 5800-6500K representative symbol: RR.
  4. Power factor: and power compensation of the power conversion source. The magnitude of the power factor depends on the power factor of the drive power source. The greater the power factor, the better the conversion efficiency
  5. Heat dissipation capability: The heat dissipation capability of LED products directly affects the service life of the product and the light decay rate. Products with higher power and longer lighting times require higher heat dissipation. Conventional LED products use a metal enclosure with internal or external heat sinks to dissipate heat from the lights.
