The light source structure of the x ray collimator is the point light source structure. Let’s see what the point light source structure is.
The light source structure of the x ray collimator is the light characteristic of the beam limiter. When the beam limiter is installed at the required distance from the focus to the installation plane, the light illumination field indicator indicates the exact illumination area. In the light source structure of the x ray collimator, there is a switch to control the on-off of the indicator lamp on the beam limiter. The self-closing lamp device is used to automatically close the lamp at a predetermined time after opening. It will reduce the operation steps, avoid forgetting and prolong the lamp life. There are two kinds of common automatic shut-off devices: mechanical and electronic. Mechanical automatic light-closing device is divided into knob type and button type. The duration of the light is determined by the degree of turning the knob or pressing the button. Electronic automatic light-closing device uses an electronic timer. After adjusting the time limit, the light is automatically turned off by a button until a predetermined time. Halogen lamp was used as the light source structure of the x ray collimator, but now there are more products using LED lamp.
