Question 1

What is an example of luminous efficacy?

Accepted Answer

Luminous efficacy, also known as luminous efficiency, has a significant relationship with energy efficiency. A lamp with higher efficacy is more efficient because it uses less electricity to illuminate. Therefore, the importance of light efficiency in terms of power saving is very great. For example, a 100W MH street light may emit 10000 lumen, which leads to a luminous efficacy of 100 lm/W. The same luminous flux could be generated with a lamp with more efficient light emitting diodes (LEDs). For example, a LED street light 60W can emit 10000 lumen as well , since it has great luminous efficacy which is about 170lm/W.

Question 2

Why is luminous efficacy important?

Accepted Answer

Luminous efficiency, also known as luminous efficiency, is closely related to energy efficiency. High-efficiency luminaires use less electricity to provide effective lighting, so they are significant in terms of power savings. High-efficiency LED luminaires produce brighter light with less energy, resulting in lower energy consumption, lower electricity bills, and a more sustainable and economical lighting solution.

Question 3

Why luminous efficiency of LED is higher than other solutions?

Accepted Answer

LED efficiency is the best because of two reasons as we think.

High spectral efficiency: LED lamps can precisely adjust the spectrum according to the needs, making it closer to the human eye's perception of light, so that the LED has a high luminous efficiency and will not produce other useless spectra.

Low energy loss: LED lamps waste very little energy on heat, concentrating electricity on the production of light. However, traditional lamps such as high-pressure sodium lamps and metal halide lamps have relatively large energy losses, such as heat loss.
