LED lamps and lanterns of significant parameters

Unit (2) the light efficiency: the luminous efficiency of lamps and lanterns, is how much power can light, LM/W (3) light intensity, luminous intensity, luminous flux in unit Angle how many known as light intensity, unit for candela ( cd) 。 (4) intensity of illumination, intensity of illumination is the most commonly used evaluation

(2) the light efficiency: the luminous efficiency of lamps and lanterns, how much power can light is unit, unit LM/W

3. Light intensity: is the luminous intensity, LED street lamp, luminous flux in unit Angle how many known as light intensity, unit for candela ( cd) 。

(4) intensity of illumination, intensity of illumination is the most commonly used evaluation index of street light effect, refers to the amount of the flux per unit area, the unit for lux ( LX） 。 : the average illuminance computing area, all the selected point average illuminance.

5 color temperature: it is said the scale of the light source the light color, simple said is the color of the light, color temperature from low to high performance for yellow - respectively White - Blue. Usually road lighting to yellow ( Below 3000 k) , warm white ( 3000 - 5500 k) Is white ( 5500 k - 6500 k) And so on.

6 illumination uniformity, road lighting, a measure of road lighting integral effect, within the scope of evenness refers to calculate the minimum intensity of illumination and the ratio of the average illuminance. The higher evenness, illustrate the less dark space pavement, it looks more comfortable.
