What are the problems in LED luminaire for road and street lights?

LED luminaire for road and street lights refers to the lighting set up for the road and its ancillary facilities. 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. So what are the problems in LED luminaire for road and street lights? Let's take a look together next.

This is the content list:

l Problems of LED luminaire for road and street lights in road lighting application standards

l LED luminaire for road and street lights in the road lighting color rendering index and color temperature issues

l LED luminaire for road and street lights spectral issues on human health and safety

l The problem of vicious competition and actual energy saving of LED luminaire for road and street lights

Problems of LED luminaire for road and street lights in road lighting application standards

As a new light source, LED luminaire for road and street lights in road lighting standards, there are not unified mandatory standards in China, but this does not mean that there is no standard for road lighting applications. Motor vehicle road lighting is designed for the visual operation of the driver, LED luminaire for road and street lights should be selected "urban road lighting design standards" cJJ45-2006 "luminance standards", that is, the road surface Average brightness, total uniformity of road brightness, longitudinal uniformity, glare limit, environmental ratio and induction as evaluation indicators. There are semiconductor experts and street light enterprises to promote the illumination uniformity of LED street lights, rectangular spot formation uniform illumination, etc., widely spread, resulting in misguided, wasting a lot of humans, financial and material resources there is no real understanding of the nature of LED luminaire for road and street light needs.

LED luminaire for road and street lights in the road lighting color rendering index and color temperature issues

LED luminaire for road and street lights has a low value of CRI and the light color quality can be very good.  Conversely, high CRI values do not necessarily guarantee good color light quality. For LED luminaire for road and street lights, traditional lighting based on the blackbody radiation theory to develop the color rendering evaluation criteria CRI has great limitations.

LED luminaire for road and street lights spectral issues on human health and safety

LED luminaire for road and street lights emits a lot of blue light, which is poorly absorbed by the human eye and can easily cause glare. At the same time, the blue light emitted by LED luminaire for road and street lights may inhibit the body's ability to produce melatonin, which helps people fall asleep.  Melatonin is a very important neuroendocrine hormone, can regulate human physiological rhythm (biological clock) so that people adapt to changes in the external environment, there are such as sedation, hypnosis, immunity, excitement, anti-aging, anti-tumor, and other effects are being studied. Therefore, LED luminaire for road and street lights on the evaluation of the quality of the lighting source can not only take visual cognition as the standard but also evaluate from the visual cognition and non-visual perception of two aspects, in-depth study of the size of the impact of non-visual.

The problem of vicious competition and actual energy saving of LED luminaire for road and street lights

LED luminaire for road and street lights market is the meat and potatoes in the eyes of every LED enterprise, but a time the impulsive behavior of applicants blindly low prices procurement is paying a painful price. Many LED luminaire for road and street lights enterprises blind investments, quick success, just buys the module assembly, not to talk about innovation. Some of the LED luminaire for road and street lights application enterprises with R & D investment are also carried out on heat dissipation, optical, structural, electrical and other technically repetitive R & D, and the science of lighting, the impact of light on people research is not involved. Many enterprises generally on the common technology of repeated research and development, resulting in a waste of resources, LED luminaire for road and street lights cost remains high, and then the "vicious circle" affect the application of market development. Inferior quality LED products to flood the market, many enterprises can't improve the technology content with heart, in the process of fighting price led to China's LED luminaire for road and street lights industry go downhill.

LED luminaire for road and street lights will be tested before leaving the factory to maintain the healthy development of LED luminaire for the road and street lights market. If you are interested in LED luminaire for road and street lights, you can contact us at www.latticelighting.com.
