Outdoor areas that rely on excellent lighting design to improve safety and efficiency, a few common examples are streets, driveways, parking lots and pedestrian areas. In outdoor lighting, LED lighting is rapidly becoming a strong competitor of high-intensity discharge lamps (HID). What are the main considerations for LED and HID outdoor lighting sources and outdoor space lighting design?
Q: How to measure the color of outdoor lighting? What is the scope of application of outdoor lighting?
Answer: The industry standard tends to correlated color temperature (CCT) 4000K, color rendering index (CRI) 70. The acceptable range is usually CCT3000K-5000K, and CRI is 70 or 80.
Q: What is the design difference between street lighting and park or other outdoor space lighting?
Answer: Each application represents a different set of visual tasks, which need to be solved by applying design technology and optical technology. Different environments have different requirements for safety, identification and speed of identifying objects.
Q: What factors should be considered when planning outdoor lighting design?
Answer: When planning outdoor lighting design, the following five points should be considered:
1. Consider the visual tasks required for navigation or taking up space;
2. Determine the lighting level and consistency issues required to perform the task;
3. Ensure that the overall lumen output and installation of the lamp are high to reduce glare and improve visibility;
4. Respect the red line of the land and reduce light intrusion;
5. In order to prevent light pollution, choose lamps that minimize the light on the horizon.
Q: What role do light distribution and glare play in outdoor lighting design?
Answer: Careful selection of lighting distribution will help ensure that the visual environment can be evenly illuminated. The lamps distribute light at a sufficiently low angle to prevent over-brightness and glare. This increases visibility and a sense of security.
Q: In terms of energy efficiency, does HID lamp or LED perform better? Why is this important for outdoor area lighting?
Answer: In terms of energy consumption and light utilization, LED lighting is already more efficient than HID lamps, thereby reducing the cost of ownership per luminous lumen. Today, the market has more in-depth education on LED light sources, so that end users can choose LED lighting with confidence.
Q: Is lumen maintenance a concern for any light source? How does the durability of LED affect outdoor lighting?
Answer: The lumen maintenance rate of HID lamps requires replacement of lamps every three to five years. In contrast, LED lamps can be extended to more than 20 years. The LED has a low failure rate and low lumen maintenance rate, which prolongs the lamp replacement maintenance cycle and reduces maintenance costs.
Q: In general, HID lamp or LED, which is more cost-effective for outdoor lighting?
Answer: Modern LED lighting fixtures provide control options, which can turn off the lighting or reduce the power when the lighting is not needed, which can save energy and protect the environment. If you also consider low cost of ownership, then LED is a better choice.
