Let’s discuss the factors that need to be considered when choosing the right LED street light. Here is a comprehensive guide to help you choose the right LED street lights.

      ◢  Brightness and lighting requirements factors

Confirming the required brightness and lighting needs is an important step in selecting the appropriate LED street light. Here are some guided steps:

• 1. Understand lighting standards and codes:

  Check local and national lighting standards and codes. These documents usually specify the lighting levels and requirements required for different types of roads and sites.

• 2. Consider the usage scenario:

  Different scenarios require different lighting levels. For example, urban arterial streets, alleys, parking lots and industrial areas may have different lighting needs. Consider uses such as pedestrian areas, vehicular circulation areas, or other special needs.

• 3. Use lighting calculation tools:

  Take advantage of online lighting calculation tools that can help you calculate the required brightness levels based on the area’s size, use, and lighting standards. These tools often provide detailed input parameters such as photometric distribution, position and height of luminaires, etc.

• 4. Consider reflection and environmental factors:

  Consider the surrounding environment and terrain. Some locations may require higher lighting levels to compensate for trees, buildings or other objects that block the spread of light.

• 5. Consult a professional lighting designer:

  If you are unsure about your lighting needs, you can consult a professional lighting designer. They can provide customized advice based on specific scenarios, ensuring compliance with local and national lighting standards.

• 6. Field testing:

  During the field testing phase, sample lamps can be used for experiments. This helps to visually understand the brightness, uniformity and adaptability of the fixture. During field testing, observe the lighting effects to ensure that requirements are met.

• 7. Dimming and intelligent control:

  Consider whether dimming and intelligent control functions are needed. With the dimming function, lighting levels can be adjusted according to actual needs, improving energy efficiency. The intelligent control system can automatically adjust according to different times and usage scenarios, further improving the flexibility and efficiency of the lamps.

• 8. Review actual application cases:

  View actual application cases for similar scenarios or projects. Learn about other projects’ lighting designs and types of fixtures used to gain lessons learned to ensure a better fit for your lighting needs.

        ◢  Color temperature and color index factors

Confirming the color temperature and color index of LED street lights is an important step to ensure ideal lighting effects. Here are some suggestions for confirming these two parameters:

• 1. Understand the color temperature range:

  Understand the characteristics of different color temperature ranges. Color temperature is expressed in Kelvin (K). Common color temperatures include warm white light (about 2700K to 3000K), natural white light (about 4000K to 4500K) and cool white light (about 5000K to 6500K). Understanding these ranges can help you choose a color temperature that works for your specific environment.

• 2. Consider the usage scenario:

  Different scenarios and applications require different color temperatures. For example, residential areas may be better suited to warm white light, while highways may require cool white light to improve visibility. Consider the nature and purpose of the scene to determine the most appropriate color temperature.

• 3. Understand the color index (CRI):

  The color index measures the ability of a light source to restore the color of an object. Generally speaking, the higher the CRI value, the more realistic the color reproduction. Choose LED street lights with high CRI values to ensure more accurate color display of objects in the lighting environment.

• 4. Refer to similar scenarios:

  refer to actual application cases of similar scenarios or projects. Knowing the color temperature and CRI values chosen in other projects can help understand how colors will behave in different environments.
