Abstract
Disclosed is an LED-based bulb-type lamp, including a cooling structure and a plurality of LEDs thermally connected to the cooling structure. The lamp includes at least three separate LED arrays oriented substantially parallel to its central longitudinal axis, such that the LEDs are interspersed among a plurality of light-transmission sub-areas of the LED-based lamp. One or more portions of the cooling structure of the lamp extend to its outer surface, as assembled, such that light-transmissive and heat-dissipating areas are spread over the outer surface, for example, in an alternating manner.
