Next, Xinzhao photoelectric small series to give you a detailed introduction
What is a shadowless lamp?
The principle of no shadow lamp is
The principle of diffuse reflection of light is used.
The shadowless light emits light in all directions. When it is shot on the surface of the object, there will be different directions of light being fired, so that the shadowless lamp can be shadowless
Shadows are formed by light. The shadows on earth are different. Carefully observe the shadow under the light of the electric lamp, and find that the middle part of the shadow is particularly dark and slightly shallow around. The dark part in the middle of the shadow is called the original shadow, and the gray part around it is called the shadow. These phenomena are closely related to the linear propagation of light. If a column of tea is placed on the table, and a candle is lit next to it, the barrel will cast a clear shadow. If two candles are lit near the tea barrel, two overlapping and non coincident shadows will be formed. The overlapping part of the two shadows has no light, it is completely black, which is the original shadow; There is only one candle next to the shadow, which is half light and half dark. If three or four candles are lit, the shadow part will gradually shrink and the shadow part will appear many levels. It is also true that an object can generate a shadow composed of the original shadow and the half shadow under the light of the electric lamp. Obviously, the larger the area of the luminous object, the smaller the original image. If we put a circle of candles around the above tea barrel, the shadow will disappear completely and the half shadow will be too light to see. Scientists have made the operation light according to the above principle. It arranges the lamps with high luminous intensity into a circle on the lamp panel, and synthesizes a large area of light source. However, we also used this principle to make the camera lights, which reduced the workload for the later shooting personnel. The products that were shot with the camera can be used directly without cutting the pictures. Therefore, it is loved by the majority of photography friends.
