Abstract:
An LED bulb (10) includes a metal lead frame (50) on which is directly mounted a low beam set of first LED dies (14), a high beam set of second LED dies (16), and a high beam set of third LED dies (16). The lead frame (50) is bent so that the first LED dies (14) face upwards and the second and third LED dies (16) face sideways and in opposite directions. A thermally conductive opaque plastic body is molded around the lead frame and exposes the LED dies. The body includes light-blocking features (26, 32, 40) to cause the light emission pattern of the first LED dies (14) to be limited in lateral and vertical directions for a low beam of a headlight. The light-blocking features also cause the light emission pattern of the second and third LED dies (16) to be less limited in the lateral and vertical directions for a wider high beam of the headlight.
