Built-in Lithium Battery LED Street Light

2021-08-05

Power factor

Useful power divided by total power, this is the power factory. Normally higher power factory, the useful power is higher, and more power are saved. Meanwell LED lighting driver power factory, PFC is always 0.97-0.98. Less power is loosed.

Usually the LED light driver will have 8%-10% loose on the power.

Basic knowledge for lighting.

Luminous flux, LM.

If we add all the lights up for one lamp, that emit in a specific time, or we say, to add up all lights that emit per second, this is called luminous flux, LM.

Illuminance

In a specific area, how much light it is lighted. The unit is LUX or LX.

Color temperature, CCT.

The color of the light we can see is called color temperature.

For outdoor LED lighting, like LED street light, the color temperature is always 5000-5500K, this is very comfortable white, if make it 6000k, it is miserable white, make people uncomfortable.

Color renting index, CRI

All objects have its own color, when different CCT light source light up one object, it reflect different color, higher CRI, the ability to present object’s natural color is higher. In different working condition, the required CRI will be totally different.

Luminous efficiency

If you want to know how much your LED lamp can save you electricity bill, this is very important.

Luminous efficiency means the lamp’s ability to turn electricity power into light. Higher luminous efficiency, the less lamp we will require. The unit is LM/W.
