LED assembly has several circuit boards each with several mountings for LEDs, each circuit board being mounted on baseboard with electric connections

摘要

The baseplate (30) has an electric connector (40). Several parallel circuit boards or mounting boards (10) are connected to the baseboard and carry various numbers of LEDs (20). Each led has a contact pin (21) and a heat conductor disk or tongue (22) for cooling the LED. The assembly of LEDs may have a standard screw fitting of the pattern normally used on incandescent electric light bulbs.
