LED luminaire for road and street lights is used to improve the safety of vehicle driving and pedestrian walking at night and prevent traffic accidents. Properly set, it can improve traffic conditions, reduce driving fatigue, improve road capacity and effectively reduce traffic accidents. So how to judge the quality of LED luminaire for road and street lights lighting? Let's take a look at it next.


This is the content list:

  • lumination Criterion

  • Brightness requirements

lumination Criterion

LED luminaire for road and street lights Illuminance is an objective physical quantity that represents the amount of luminous flux per unit area of the road surface that is illuminated. It can be seen that the value of LED luminaire for road and street lights illuminance and all the characteristics of the observer (such as eyesight, observation angle, age, etc.) and the traits of the road surface is not related, only with the choice of lamps, lamps, and lanterns layout and road width and other circumstances. It is a quantity that is invisible to the eye. Sometimes LED luminaire for road and street lights illumination is very high, but the surface color is very dark, looks rather dark, and not as bright as the low illumination but light color surface, easy to produce illusion and misleading, from the other hand, LED luminaire for road and street lights illumination of, On the other hand, the calculation and measurement of LED luminaire for road and street lights is very simple and easy to carry out.

LED luminaire for road and street lights calculation is to uses the inverse cubic theorem of cosine to calculate its size. LED luminaire for road and street lights measurement is to use illuminance meter can be very convenient to measure.

Because of such characteristics, the illuminance of LED luminaire for road and street lights as an evaluation indicator should be objective and applicable in the case of many targets on the road of pedestrian walkways and non-motorized vehicles, the direction and object of observation are uncertain, and the age and height of the observer are uncertain. For this reason, countries on non-motorized roads and sidewalks are using LED luminaire for road and street lights as the technical parameters of the lighting quality level assessment.

Brightness requirements

The visual object of the motorway is the driver of the car, see the LED luminaire for road and street lights on the road surface and the brightness of the road, to LED luminaire for road and street lights as a criterion is closer to the eye to see the actual situation of the objective physical quantity. The brightness of a point on the road surface is related to many factors, in general, the driver's position from the observation point, eye height, and direction of vision, angle of view and road surface material (reflection characteristics), and the wet condition of the road surface, etc. The state or data of these factors all affect the brightness data and subjective feeling of the road surface, which is a far more complex physical quantity than illumination. LED luminaire for road and street lights is more realistic to reflect what the eye sees and expresses the feeling of the eye. Therefore, countries around the world use LED luminaire for road and street lights as an indicator in the evaluation of LED luminaire for road and street lights to measure and calculate, for this reason, the various variables mentioned above are unified or standardized, to produce a unified evaluation and calculation method.
