AN LED LIGHTING ASSEMBLY AND AN LED RETROFIT LAMP HAVING THE LED LIGHTING ASSEMBLY

摘要

The present invention relates to an LED lighting assembly, having a printed circuit board (3) carrying an LED chip (4), a heat sink (2) thermally connected with the printed circuit board (3), wherein the LED lighting assembly further comprises a light guide body configured as a bulb (5), the light guide body having an inner surface (6), an outer surface (7) as a light emergent surface and an end surface (8) as a light input coupling surface of light from the LED chip (4), and wherein the inner surface (6) is structured so as to form a reflecting surface (10) towards the outer surface (7) to make at least part of light from the end surface (8) to be reflected and exit through the outer surface (7). In addition, the present invention further relates to an LED retrofit lamp having the LED lighting assembly of the type above.
