Description

Technical Field

[0001] The utility model relates to a protective device, in particular to a protective device for a photometer. Background Art

[0002] A light meter is an instrument that is specifically used to measure light intensity and brightness. It measures the light intensity (illuminance), which is the degree to which an object is illuminated, that is, the ratio of the luminous flux obtained on the surface of the object to the illuminated area. A light meter is usually composed of a selenium photocell or a silicon photocell and a microammeter. A light meter consists of a photosensitive element and a display device. The photosensitive element displays the light intensity through the display device, so that people can clearly understand the intensity of the light. However, the screen of the display device is relatively fragile. Once a collision occurs, the display screen will shatter and become unusable. Ordinary light meters do not have the function of protecting the screen. Therefore, it is necessary to design a protective device for light meters to solve this problem. Utility Model Content
