A digital broadcast transmittingreceiving system and a method for processing data are disclosed. The sensors may include any suitable type of sensor, including for example a proximity sensor, an ambient light sensor, or any other suitable type of sensor that emits or receives radiation from the environment. The camera system further generates a temporally filtered image signal corresponding with a temporal characteristics of the image signal over a selected number of prior image frames. The spectral purity of normal incidence radiation may be enhanced, such that DUV radiation is diminished relatively stronger than EUV radiation. By this method, LED bulb and secondary optical lens can contact directly and be located precisely. The second internal conductor is connected to the first internal conductor at the end surface.
