Fog and haze conditions cause lighting effects which are not very good to the users. Therefore, it is highly recommendable to try as much as possible to reduce these lighting effects. One can achieve this by doing various things such as the following.

Lighting penetration performance in the haze condition

Light normally penetrates in the air and this is seen by the scattering effect of the particles. Rayleigh and Mie light scattering theory explanation is widely recognized all over and mainly analyzes the scattering effect of the different particle sizes. The Rayleigh scattering theory states that the molecular and very small particles of between 1 and 10 light wavelength, their scattering effect is usually determined by the wavelength of the light. The Mie scattering states that the particle diameter is larger than the wavelength of the light. This indicates the scattering of light in fog and haze by the Mie scattering theory judgment.

The wavelength of the light does not affect the performance of the amount of light penetrating. Therefore, the fog and haze conditions in the light are throughout the performance and wavelength of both the light and color temperature regardless of anything else. However, this is not true and it is just a misunderstanding of the Rayleigh scattering theory.

The key factor of the lighting design in fog and haze conditions

The primary conditions of the lighting design are non others but the security issues. The lighting design has particular emphasis on this issue. By the theoretical analysis, the wavelength of the illumination light colors as well as lighting effects in the haze weather conditions does not affect. Therefore, the light color rendering index is usually considered as a very important indicator of the lighting effects. In the haze and fog, the colored lighting is seen easily in the white haze and thus the lighting design selected should be high color reproduction lighting with higher visibility.

Here are reasons why people think lighting effects are better in the fog and haze of the red light and yellow light. In the conventional applications, the high pressure sodium street lighting designers prefers it since it is the best choice for the haze conditions. This is because of the yellow lights and white haze surrounding the environment. However, this is not satisfactory in the lighting effects.

Recommendations for the LED streetlight

According to the theory with the actual situation, it is concluded that the lighting effects under the haze and fog is not actually determined by the wavelength of the light source, color rendering index as well as the color temperature. This can greatly help to improve the lighting effects. In addition to this, due to the low color temperature of the lighting, the light can easily be found. This plays an important role in signal lighting to help pedestrians and drivers advance warning in front of the presence of dangerous environment.

In the fog and haze conditions, the LED streetlight is required to achieve the desired lighting effect. Thus, it is upon the buyer to select a LED streetlight which has high color rendering index as well as low color temperature.
