Street lights are widely used in various places that require lighting. With the advancement and development of science and technology, it has changed from metal halide lights to LED street lights.
LED street light is a kind of road lighting equipment that uses LED (Light Emitting Diode) as the light source. Compared with traditional street lights, LED street lights have higher energy efficiency, longer lifespan and better light quality.
what are the advantages of led street lights
A.High luminous efficacy and low energy consumption
Traditional street light sources generally emit light to the entire space, but only the road surface for driving and pedestrians needs to be illuminated by street lights. Therefore, in the design of street lights, in order to make the light as uniform and concentrated as possible on the road surface, it is necessary to use curved reflectors. Collect light and direct it in the desired direction. In the process of light propagation, due to the blocking of the light source and the absorption of the reflective surface, the light output efficiency of the street light is only 65%-70%. In contrast, LED street lights, because of their good directionality, when using secondary optical lenses, the efficiency of lights can reach about 80%. If the optical design is carried out three times, the light output efficiency of the LED street light can reach 85%-90%.
High-intensity discharge (HID) street lights can generally only be dimmed in a small range, while LED street lights can achieve dimming control from 0% to 100%, and can flexibly adjust light output according to ambient light and traffic conditions. Reduce unnecessary energy consumption while ensuring lighting needs. It can be seen that for road lighting, which accounts for about 15%-20% of the total lighting power consumption, the large-scale implementation of LED street lights is of great significance for energy saving and carbon reduction.
The lifespan of street lights directly affects the maintenance cost of the entire road lighting. At present, the lifespan of high-pressure sodium lights is generally about 20,000 hours, the lifespan of high-pressure sodium lights for road lighting is only about 5,000 hours, and the lifespan of high-power LEDs is generally 50,000-70,000 hours.
The CRI of LED can reach about 80, which is basically close to natural light, and the presentation of color is more realistic, and it can better reflect the color of the object itself. The high CRI of LED will undoubtedly help drivers and pedestrians identify targets, and provide better traffic conditions under the same road surface brightness.
The incandescent light is turned on at one point, but the actual start-up time is 0.1-0.2 seconds. Gas discharge lights such as high-pressure sodium lights and metal halide lights take tens of seconds or even ten minutes from starting to stable light output. After being turned off, it takes 3 to 6 minutes to cool down before starting. The start-up time of LED is only tens of nanoseconds (ns), and there is no waiting time for restart, and LED lights can normally work in a continuous on/off state.
E.Easy for optical design
LED is small in size and can emit light directionally on a half-plane. It is very suitable for optical design with lenses or reflectors to obtain ideal light distribution and high light efficiency.
F.Strong shape plasticity, firm structure
The shape of LED street lights has strong plasticity, and can reflect decorative and local cultural characteristics through shape design, adding the value of urban imagery. LED lights can be made very strong in structure through reasonable design.
In addition to the above advantages, LED street lights also have some other characteristics. Firstly, LED street lights can be used with NEMA or ZHAGA bases to realize intelligent lighting in cities, making energy consumption lower and maintenance more convenient. Secondly, the color temperature of LED street lights can be adjusted as needed to meet different lighting needs. Moreover, LED street lights have no ultraviolet and infrared radiation, and are not harmful to the environment and human health.
Due to the various advantages of LED street lights, more and more cities and roads have begun to use LED street lights for lighting. LED street lights can not only provide better lighting effects, but also save energy and reduce maintenance costs, which is of great significance to the sustainable development of cities and environmental protection.
