What are the main considerations of LED street light and HID for outdoor lighting ?
The outdoor areas that rely on superior lighting design to improve safety and efficiency are common examples of streets, lanes, parking lots, and pedestrian zones. In outdoor lighting, LED street lights are rapidly becoming a contender for high intensity discharge (HID) lamps.
What are the main considerations of LED street light and HID for outdoor lighting ?
Question（Q）: what is the scope for outdoor lighting?
Answer(A): industry standard tends to color temperature (CCT) 4000K, color rendering index (CRI) 70. The acceptable range is usually cct3000k-5000k, and CRI is 70 or 80. The color temperature range of LED street light is 3000-6500k, which meets the requirement of color temperature in different zones.
Q: what are the different between street lighting and parks or other outdoor lighting in design?
A: each application represents a different set of visual tasks that need to be solved by applying design techniques and optical techniques. Different environments have different requirements for security, identification, and speed of identifying objects.
Q: what factors should be considered when planning outdoor lighting design?
A: when planning outdoor lighting design, consider the following five points:
1,Consider the visual tasks required for navigation or occupancy;
2,Determine the lighting level and consistency issues required to perform the task;
3,Make sure the overall lumen output and installation are high to reduce glare and improve visibility;
4,Respect the red line of land and reduce light invasion;
5,To avoid light pollution, choose lamps that minimize light on the horizon.
Q: what role does light distribution and glare play in outdoor lighting design?
A: carefully selecting the lighting distribution will help ensure that the visual environment is evenly illuminated, and LED street light is distributed in a sufficiently low angle to prevent too bright and glare. This increases visibility and security.
Q: HID lights or LED street lights in terms of energy efficiency, which do better? Why is important for outdoor lighting?
A: LED street light is already more efficient than HID lamps in terms of energy consumption and light utilization, reducing the cost of each lighting. Today, the market has a deeper investment in LED light source, so that end users can choose LED street light safely.
Q: is the lumen maintenance rate a concern for any light source? How does the durability of LED street light affect outdoor lighting?
A: the lumen maintenance rate of HID lamps that every two to three years. By comparison, LED street light can be extended beyond five years. The low failure rate of LED street light, low maintenance rate, prolonged change of lamp maintenance cycle, reduced maintenance cost.
Q: in general, HID lamp or LED street light, which are more cost-effective in outdoor areas?
A: modern LED street light provide control options that can be turned off or reduced when lighting is not needed, which can save energy and protect the environment. If you also consider low ownership costs, LED street lighting is a better option.
