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.

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
