Comparison Between High-Pressure Sodium Lights And LED Street Lights
Combined with the current road lighting design features, road lighting with high-pressure sodium lamps has the following shortcomings:
Under the high-pressure sodium lamps, the light is very high. But at the middle of two adjacent poles, the illuminance only reaches about 10-20% of the direct illumination direction, which cannot effectively meet the lighting demand, there will be a big darkness between two poles.
The efficiency of the high-pressure sodium lamp emitter is only about 50-60%, which means that in the illumination, nearly 30-40% of the light is illuminated inside the lamp, the overall efficiency is only 60%, there is a serious waste phenomenon.
Theoretically, the lifetime of high-pressure sodium lamps can reach 15,000 hours, but due to grid voltage fluctuations and operating environment, the service life is far from the theoretical life, and the damage rate of lamps per year exceeds 60%.
The LED street light have the following advantages:
As a semiconductor component, in theory, the effective life of an LED street light can reach 100,000 hours, which is far higher than high-pressure sodium lamps.
Compared with high-pressure sodium lamps, the CRI of led street light fixture can reach ＞80, which is quite close to natural light.
Under such illumination, the recognition function of the human eye can be effectively utilized to ensure road safety.
When turn on the street light, the high-pressure sodium lamp needs a certain time from dark to bright, which not only causes waste of electric energy, but also affects the effective development of intelligent control.
In contrast, led street light fixture can achieve optimal illumination at the moment of opening, so that good intelligent energy-saving control can be achieved.
From the perspective of the illuminating mechanism, the high-pressure sodium lamp uses mercury vapor luminescence. If the light source is discarded, if it cannot be effectively treated, it will inevitably cause corresponding environmental pollution.
The LED street light adopt solid-state lighting, and there is no harmful substance to the human body. It is an environmental friendly light source.
From the aspect of optical system analysis, the illumination of high-pressure sodium lamp belongs to omnidirectional illumination. More than 50% of the light needs to be reflected by the reflector to illuminate the ground. In the process of reflection, part of the light will be lost, which will affect its utilization.
The LED outdoor street light belong to one-way illumination, and the light is intended to be directly directed to the illumination, so the utilization rate is relatively high.
In high-pressure sodium lamps, the light distribution curve needs to be determined by a reflector, so there are great limitations.
In the LED street light, a distributed light source is adopted, and the effective design of each electric light source can show the ideal state of the light source of the lamp, realize reasonable adjustment of the light distribution curve, control the distribution of light, and keep the illumination relatively uniform within the effective illumination range of the lamp.
At the same time, the LED street light have a more complete automatic control system, which can adjust the brightness of the lamp according to different time periods and lighting conditions, which can achieve good energy saving effect.
In summary, compared with the use of high-pressure sodium lamps for road lighting, LED outdoor street light are more energy-efficient and environmentally friendly.
24/48V solar led street light alsoavailable, our led street light is 100% suitable for solar system.
