Abstract:
The invention concerns a circuit board with electrical components which are inserted, together with their insulating elements (3), in throughbores (10) in the circuit board (9). The components project out slightly beyond the upper and lower surfaces of the circuit board. The projecting ends have contact surfaces which are soldered to conductions tracks on the circuit board. The lower ends of the components have hemispherically domed or rounded conical tips with contact surfaces which fit into conductor tracks designed as soldering eyes (7) on the circuit board (9) and are soldered to these soldering eyes . The upper ends of the components have several contact surfaces (1.1, 1.2) which are insulated from each other and which are joined to contact elements (2.1, 2.2) projecting out away from the insulating elements (3), the contact elements (2.1, 2.2) being joined by solder (5) at intervals round the bores (10) to conductor tracks (6) on the upper surface of the circuit board.

The electronic components of an electrical switching and control apparatus (10) are arranged on a hybrid board (11) which is connected with plug contacts (14). To achieve a compact, extremely simple design in which the heat losses at the output components (13) of the hybrid circuit (11) are dissipated, the flat areas (14b) of the plug contacts (14) inside the housing of the device lie against the rear face of the hybrid board (11) to which the output components (13) are contiguously secured. The ends (14c) of the contact parts (14) are in direct contact with the connectors (12) of the hybrid board (11). An apparatus of this type is suitable for switching and control applications and is particularly advantageous when used in motor vehicles.

Abstract:
A light emitting diode (LED) has an integrated heat sink structure for removing heat from an LED junction and for dissipating heat from the junction to the ambient air. The anode and the cathode both either act as or are coupled to a thermally conductive material which acts as the heat sink. In one embodiment, the heat sink forms a mounting configuration that allows air to circulate around multiple surfaces to maximize heat dissipation. As a result, the LED junction temperature remains low, allowing the LED to be driven with higher currents and generate a higher light output without adverse temperature-related effects.
