In urban lighting, road lighting system is the indispensable important constituent, the quality of the road lighting not only can reduce the driving safety at night problems, also can add light for the night.
Can through the observation, the most of the street lamp light source in urban lighting system still adopts the traditional high pressure sodium lamp, rather than LED lights, therefore exists low light efficiency, low color temperature, color rendering index lower three low problem.
With the development of LED lighting, three low problem is expected to be resolved, lighting quality is higher.
At the same time, promote the development of road lighting energy saving technology, is the main trend of lighting industry, here we come to the simple explore the solution of for your reference.
LED street light solution compared with the traditional light source, LED light source with high light efficiency, adjustable color temperature, color rendering index is higher, smaller, less heat, and many other advantages, the current as the fourth generation light source has to consolidate the position of the mainstream of lighting.
LED lights on the drive power set also need special attention, at present there are ac type power LED street light and solar LED two forms.
Among them, the LED driver power supply are often able to convert ac voltage into dc voltage, at the same time pay attention to and the current match.
Under the background of street lamps use fewer, operation and design of drive power supply is relatively easy, in the street lamps use quantity is large, the feedback control of the driving power supply should be strengthened.
LED road lighting problems which lead to the user for the LED lighting lamps and lanterns is confused problems mainly from two aspects: (
1)
The lack of lighting engineering quality control in the new road lighting project, tend to sacrifice quality of road lighting energy saving utility maximization problem.
This kind of question is, is mainly due to the completion inspection and acceptance period, only consider the lanes of illuminance and the level of uniformity, and ignore the quality of the actual lighting.
The various problems caused by the problems emerged, disability glare, environment than is not up to standard, the phenomenon such as pavement vertical illumination is not up to standard.
(
2)
Glare problem while the LED lamps and lanterns of light more high quality, but if not doing a very good job anti-dazzle, or lighting design of cloth lamp is not reasonable, will cause the user's visual induced decline, at the same time accompanied by causing problems such as discomfort glare.
LED street lamp light distribution problem: (
1)
Vertical illumination problem due to the LED light source in the process of light distribution design tend to point source alternative, easy to implement accurate light distribution, makes the vehicle inside and outside illumination difference is obvious, the light energy utilization rate and the intensity of illumination uniformity which embodies the outstanding performance of LED lighting light source.
However, if you consider the lanes lateral sidewalk lighting and other factors, such as face recognition, this kind of light and shade of light source with light but not easy to meet the requirements.
(
2)
Discomfort glare problems cause discomfort glare problems mainly by the observation Angle, observation distance and the choice of the surface brightness of lamps and lanterns.
In terms of street lamps, viewing Angle and observation distance both are changed, only the surface brightness of lamps and lanterns to choose from.
Actually, these problems mainly due to problems with the LED street lamp light distribution, business drivers are the manufacturer and user of energy drive, a contradiction caused by the phenomenon.
LED lights can realize the energy saving of road lighting, but the one-sided emphasis on energy conservation will bring other problems.
In a word, road lighting quality standards is a comprehensive evaluation system, unilateral pursue lighting energy-saving inevitably leads to the loss of lighting quality.
So have to say, rather than unilateral emphasis on energy conservation, it is better to choose can both illumination and energy saving, but also can control the glare of the product, its use in the lighting solution.
