Abstract
The present invention relates to a luminous means comprising an enveloping bulb, a base, a first LED and a second LED, which are assembled on a planar printed circuit board, to be precise on the opposite side thereof in relation to a thickness direction, wherein a first diverging lens is mounted on the first side of the printed circuit board in a manner assigned to the first LED and a second diverging lens is mounted on the second side of the printed circuit board in a manner assigned to the second LED for the purposes of homogenizing the light distribution generated by the luminous means, and the light emitted by the respective LED has a widened luminous intensity distribution downstream of the respective diverging lens in comparison with upstream of the respective diverging lens.
