What Kinds Of LED Lamps Is Good LED Road Light?

There are many kinds of LED lamps on the lighting market.If you want to buy led road light,which is the best lamp?In general, there are issues to consider, such as wattage, power consumption, and whether it is bright enough.These common-sense concepts affect the choice of LED lighting lamps, and also affect the comparison of good and bad points.

It's easy to misunderstand that the higher the wattage, the brighter the light.Of course, the same wattage of LED street lamps is also the cheaper the better, which is also a confusing concept.Wattage and brightness are not necessarily the same, brightness is also called luminous efficiency, we should pay attention to the luminous efficiency.

The luminous efficiency is the ratio of the luminous flux emitted by an electric light source to its power, in lumens/watts (LM /W), which is the most important technical parameter to evaluate the luminous efficiency of an electric light source.Luminous flux is the amount of light emitted per unit of time, expressed in lumens.The greater the luminous flux of the light source per unit of power, the higher the conversion efficiency of electric energy, that is, the higher the luminous efficiency.

Firstly,average brightness and average illuminance

From the driver's point of view, the driver's judgment of road conditions mainly depends on the average brightness and average illumination of the road.At night, the human eye is in the middle vision state, and the color difference of the object is low. It mainly depends on the brightness and background of the object to distinguish, so the brightness and illuminance of the road will affect the driver's contrast, as well as the contrast between the brightness of the object and the road.

Secondly,the uniformity of brightness and illumination of road surface

If the road brightness and illumination are not uniform, too bright road will cause visual glare, while too dark road will become a visual dark area, so that drivers can not recognize nearby obstacles, causing safety problems.

Thirdly,glare restrictions

In other words, glare is the result of high brightness or brightness contrast in the visual range.Glare can be divided into two types: destructive glare and unpleasant glare.The former affects the normal visual function of the human body, but the human eye does not necessarily feel uncomfortable.The latter is the opposite: it does not necessarily affect the visual function of the human eye, but it can make the eye feel uncomfortable.

Fourthly,visual guide

For the safety and convenience of road users, road lighting is densely arranged along the road alignment to improve visual guidance.At some curves and intersections, visual guidance is more important.

The above points are based on the view of driver's night drive to analyze our led road light.In addition, there are more standards and requirements about the performance of lamp to be considered.Different application scenarios have different quality requirements for LED street lamps.Adapting measures to local conditions is the purpose of our street lamp design.
