1, led tree lights exist in the form of diffuse light, diffuse light and direct light is different from the shadow will not produce too much, so that the color brightening and darkening are more soft. But the diffused light form led tree lights need to solve an important problem is that the surface temperature of the emitting body is too high. As far as the popular led tree lights are concerned, few products can solve such problems.
2, elevation Angle, shoulder distance calculation. The calculation of elevation Angle and shoulder distance can achieve a good balance between the functional role and the landscape role. For example, if the elevation design takes into account the corresponding landscape design, it can better reflect the role of the landscape, but also meet the needs of people in the function.
When there are extremely high brightness bright spots or strong brightness contrast in the field of vision, it will make people's pupils shrink, forming light spots in the eye, destroying people's visual system to the surrounding physical space adaptation state, thus causing discomfort or visual decline. First of all, glare is caused by the high brightness of the surface of the light source. The higher the brightness of the light source, the more serious the glare. If the brightness of the light source is certain, then: the darker the surrounding environment, the more significant the glare; The closer the distance between the light source and the viewing point, the more significant the glare; The larger the apparent area of the light source, the more the number of light sources, the more significant the glare.
