Abstract (en)
[origin: WO02052524A1] The invention relates to an optical signalling device, whereby a particular given radiation property or light density distribution is achieved merely by means of an arrangement of a number of light elements (2) on a baseplate (1). Complicated optical structures are thus not necessary for production of said light distribution. The invention further relates to an optical signalling device with an outwardly bowed lens (3) for improvement of the light concentration property.
