发明名称 LED light source for a dwarf signal
摘要 The arrangement has a lamp provided with an LED base (1) in a plexiglass pipe by LED sources (6). The light is emitted by a collimator lens (2) and passed to a front lens (19) of the lamp through a dull disk (10). A control logic (11) supplies electrical power around the LED sources, and is connected with an energy balance (18) for modeling power consumption of an incandescent lamp, where energy supplied to a load resistor (20) i.e. load resistor ring, is not required for the LED sources arranged outside of a dwarf signal.
