Abstract
The utility model is composed of a case, a circuit board that is equipped in the case and an optical system. The optical system includes at least a photochromic lens or at least a photochromic euphotic layer that is attached to the surface of the lens. The photochromic lens can be a convex lens, a concave lens and a plano lens. The photochromic lens or the euphotic layer is applied to the optical system, which enables the optical system to adopt the design of a bigger fixed aperture. When stronger light shines on the lens that is provided with photochromic characteristic, the color of the lens becomes dark completely or partly to prevent excessive light from passing through. On the contrary, when weaker light passes through, the color of the lens becomes light completely or partly to let a great deal of light pass through, playing the role of adjusting light exposure automatically. The utility model doesn't need to change the structure of the original photographic equipment. The utility model adopts a lens that is provided with photochromic characteristic to replace the original lens that is provided with corresponding functions. The utility model is low in cost, low in failure rate, convenient in use and easy for popularity and generalization.
