Thermally efficient led bulb |
摘要 |
A solid-state light source 10 compatible with existing sockets normally reserved for filamented lamps may be formed with a hollow base 12 formed to mechanically and electrically adapt to a socket. A sub-assembly 14 adapted to cooperate with and fit into the hollow base 12 comprises a metal core 16 having a bulbous body 18 and a narrow, depending foot 20. A circuit board 22 substantially surrounds the metal core 16 on two sides. The board 22 is preferably formed from a flexible printed circuit board material capable of sustaining a bend radius of at least 0.25 inches (6 mm). Solid-state light sources 30, for example, light emitting diodes (LEDs) are mechanically and electrically connected to one side of the circuit board by suitable electrically conductive traces. A glass dome 34 covers the sub-assembly 14 after it is inserted into the hollow base 12 and is sealed thereto. |
