What are the outdoor area lighting design considerations? Lighting experts say

Rely on the lighting design excellence to improve the safety and efficiency of the outdoor area, several examples of common street, lane, parking lot and pedestrian area. In outdoor lighting, LED lighting is rapidly becoming a high intensity discharge lamp (HID) strong competitors. What are the LED and HID outdoor lighting, as well as the main considerations for outdoor lighting design?

Q: outdoor lighting, how to measure color? What is the scope of outdoor lighting?

Answer: industry standards tend to correlated color temperature (CCT), 4000K color index (CRI) 70. The acceptable range is usually CCT3000K-5000K, CRI is 70 or 80.

Q: street lighting and parks or other outdoor space lighting in the design?

Answer: each application represents a group of different visual tasks that need to be solved by the application of design technology and optical technology. The speed of different environment on security, identification and identification of objects have different requirements.

Q: in the planning of outdoor lighting design, what factors should be considered?

Answer: in the planning of outdoor lighting design, should consider the following five points:

1. consider the space required for navigation or visual tasks;

2. determine the lighting level and the consistency required to execute the task;

3. ensure the whole lamp lumen output and high installation, to reduce glare and improve the visibility;

4. respect the land red line, reduce light intrusion;

5. in order to prevent light pollution can be minimized, selection of lamps light on the horizon.

Q: what is the role of the light distribution and glare in outdoor lighting design?

Answer: careful selection of lighting distribution will help ensure that the visual environment can be uniformly illuminated lamps with sufficiently low angular distribution of light, to prevent light and glare. This increased visibility and a sense of security.

Q: in terms of energy efficiency, HID lamp or LED better? Why the outdoor area lighting is very important?

Answer: in the energy consumption and the utilization rate of light, LED lighting has more than HID light efficiency, thereby reducing the cost of ownership of each lighting lumens. Today, the education market of LED light source more deeply, so that the end user can safely choose LED lighting.

Q: lumen maintenance for any light source is not a concern? How to influence the durability of LED outdoor lighting?

Answer: HID lamp lumen maintenance rate for every three to five years to replace the lamp. In contrast, LED lamp can be extended to 20 years. LED low failure rate, low lumen maintenance, prolong lamp replacement maintenance cycle, reduce maintenance costs.

Q: in general, HID lamp or LED, which in the outdoor area lighting is more cost-effective?

Answer: Modern LED lighting provides control options, can turn off lighting or power down in no lighting, which can save energy and protect the environment. If you are considering the low cost of ownership, then LED is a better choice. (compiled: LED James)
