Question 1

How many types of LED light distributions are there?

Accepted Answer

The light distribution of LED lamps can be divided into symmetrical light distribution and asymmetrical light distribution according to symmetry, see the above for details. According to the installation beam angle, there are VN: very narrow, N: narrow beam, M: medium beam, W: wide beam, VW: very wide beam, among which medium includes medium narrow and medium wide. IES (Illuminating Engineering Society) subdivides different light distribution types according to the lateral light distribution and vertical light distribution of street lamps.

Question 2

Can you tell me about the different light distributions of street lights?

Accepted Answer

According to the characteristics of lateral light distribution of street lamps, IESNA divides the light distribution of street lamps into type I, type II, type III, type IV and type V. At the same time, according to the characteristics of vertical light distribution, it divides the light distribution of street lamps into VS (very short), S (short), M (medium), L (long), VL (very long). When we combine two light distributions together, we can get many combinations, such as type IS, type IIM, Type IIIM, etc. For example, narrow roads are suitable for street lamps with type I light distribution, and wide roads are suitable for street lamps with type II or type III. For another example, luminaire arrangement with small lamp spacing is suitable for type xS light distribution, and luminaire arrangement with large lamp spacing is suitable for type xM or type xL light distribution. According to these application scenarios, we often need a variety of different light distributions. In actual applications, we often use lighting simulation to help confirm which light distribution is most suitable.

Question 3

Can light distribution of post top light be customized?

Accepted Answer

Yes, we can customize the light distribution for post top lighting. It often depends on the design and use of different optical components such as lenses, reflectors, diffusers and lighting shields. In ZGSM's post top light, we often achieve the desired light distribution through the design and use of lenses and lighting shields. LED module+LED lens allows users to customise the post top lights with special lenses by combining optics to create customized lighting solutions.
