Compared With Traditional:What Are The Advantages Of LED Streetlights?

As the fourth generation of light source, the unique structure and luminous principle of LED is of great significance for daily lighting and efficient utilization of resources.Traditional street lamps are significantly less lighting effective than LED lamps on the street lighting.The main reason is that the LED light source used by LED streetlights has good unidirectional and high light output rate. Conventional emit light in all directions, relying on the reflector to concentrate the light in a single direction, with large loss and light output rate much lower than LED streetlights.

On the surface, The price of LED streetlights is more expensive than traditional, but compared with the long life, maintenance-free and high energy saving rate of LED lighting, in fact, traditional street lighting is more expensive, while LED is more economical and efficient.Compared with traditional, LED streetlights have obvious cost performance advantages, mainly reflected in the following 7 aspects:

1. Power supply system

The traditional street lamp needs a large power supply system, and the power type transformer is very expensive. Because the grid voltage is high at night, the energy consumption of the traditional light source will be higher at night(the power of the high-pressure sodium lamp can be 50% higher).And the voltage of the traditional lamp can not fluctuate too much, otherwise it will seriously affect the life of the lamp.The LED streetlights do not need large transformer. When the voltage fluctuates, the brightness of the LED street lamp does not change. When the voltage changes from 90V to 260V, the whole driver can realize constant current drive, ensuring the brightness of the high-power LED street lamp.

2. Service life

At present, the street lighting light source in circulation of lighting market is mainly high-pressure sodium lamp.Due to quality and technical problems, its service life is short, generally less than 3000 hours.While the single LED has a life of more than 50,000 hours, equivalent to more than 15 times the life of high-pressure sodium lamp, which greatly reduces the cost of streetlights maintenance and replacement.

3. Light emitting effect

The color rendering index of the single yellow high-pressure sodium lamp is very low (about 23), and the object under the irradiation is obviously distorted.While the integrated LED streetlights has a high color rendering index, which is close to sunlight, making the irradiated object more realistic in color.

4. Lighting efficiency

High pressure sodium lamp adopts spherical luminescence design, so its lighting efficiency is low.But LED uses directional light emitting, the lighting efficiency of LED streetlights is high.LED street lighting makes full use of light efficiency so as to improve the lighting efficiency.

5. Intelligent dimming system

Traditional street lamps can only achieve a small range of dimming control, such as turning off one side of the street lamp or turning off the street lamp at intervals, which will inevitably bring about the change of lighting form and easily cause safety risks.LED streetlights can achieve continuous dimming, which can flexibly adjust light output according to environmental illumination and traffic conditions, so as to ensure lighting quality and reduce unnecessary power consumption.After midnight, the whole current of LED street lamp is lowered to achieve low power operation and achieve the effect of secondary energy saving.

6. In terms of safety

Traditional lamp tubes are easy to crack under high temperature and high pressure.While LED street lighting fixtures impact resistance, earthquake resistance, no filament and glass shell, will not appear broken.No ultraviolet (UV) and infrared (IR) radiation, no harm to human body.

7. Energy conservation and environmental protection

Traditional street lamps contain lead, mercury and other polluting elements, which pollute the environment.While LED streetlights almost have no pollution from the production process to the use process until scrap, in a real sense to achieve green energy saving environmental lighting.LED streetlights save more than 60% energy than traditional high pressure sodium lamp, and has high cost performance.

LED streetlights are very good lighting fixtures of environmental protection and energy saving.The main advantages of LED streetlights is to greatly reduce the power consumption and protect the environment, which is of far-reaching significance for the promotion of efficient and energy-saving intelligent lighting equipment, effective use of light energy according to the actual lighting situation, and saving lighting electricity.Because of its many advantages, LED has gradually entered people's field of vision, become the world's best energy-saving light source, replacing the traditional street lamp.It is also the best choice for road lighting!If you need to buy LED streetlights, it is suggested to choose a regular led street light manufacturer or factory to ensure the product quality and your lighting project progress!
