A light emitting device includes a package body, a light emitting diode, a transparent resin material, and a wire. Each load carrier foot has a fixed clamping jaw and a movable clamping jaw configured to be arranged on an upper side and an opposite lower side of the respective roof rails and to cooperate with a clamping device that is configured to move the movable clamping jaw towards the fixed clamping jaw. When carriers flow, scattering of impurity ions in the active region is reduced, and the channel mobility increases. The filter is adapted to receive at least one signal within a frequency range.
