In recent years, LED lamps have been widely used. What are the characteristics of LED street lights? How to choose the right LED street lights.
1. LED street lamp is different from conventional street light. LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN based power blue LED and yellow. It has unique advantages of high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index, etc. it can be widely used in the road. LED street lamp has no light diffusion to ensure light efficiency.
However, compared with LED street light, the solar street light is powered by crystalline silicon solar cell, and the maintenance free valve controlled sealed battery (gel battery) stores the electric energy. The super bright LED lamp is used as the light source and controlled by the intelligent charge and discharge controller, which is used to replace the traditional public electric lighting street lamp.
1. LED street lamp has a unique secondary optical design, which irradiates the light of LED street lamp to the required lighting area to achieve the purpose of energy saving. The overall light efficiency of LED street lamp is stronger than that of high-pressure sodium lamp. LED street lamp can be used with lens, and the light range can be flexibly controlled after the lens is added, further improving the light efficiency.
2. The light color rendering of LED street lamp is higher than that of high-pressure sodium lamp. The color rendering index of high-pressure sodium lamp is only about 23, while the color rendering index of LED street lamp is more than 75. From the perspective of visual psychology, to achieve the same brightness, the light intensity of LED street lamp can be reduced by more than 20% on average compared with high-pressure sodium lamp. Small light decay is also the advantage of LED street lamp. The light decay in one year is less than 3%, and it still meets the road requirements after 10 years of use. However, the The high-pressure sodium light has declined by more than 30% in a year or so. The design of LED street lamp can be lower than that of high-pressure sodium lamp.
3. LED street lamp has automatic control energy-saving device, which can achieve the maximum possible power reduction and power saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time-sharing control, light control, temperature control, automatic inspection and other humanized functions. Long service life: can use more than 50000 hours, provide three years of quality assurance.
The selection of LED street light shall take the light distribution of LED street light into account. Light distribution refers to the light intensity distribution of light sources (or lamps) in all directions of space. LED street lamps with the same power usually have a wider range of illumination and more uniform light.
