Beschreibung
Zusammenfassung:	The utility model discloses an LED light source module with asymmetric light distribution, which comprises a heat dissipation base plate, a plurality of LED chips and encapsulating colloid which covers the LED chips and the heat dissipation base plate. The LED light source module is characterized in that the encapsulating colloid has a combined curved lens structure which is integrally formed and can provide eccentric rectangular light spots, so no secondary optical lens is necessary to be installed and the LED light source module is simple in structure and high in light extraction efficiency and is particularly suitable to be used as the light source for a street lamp. Furthermore, the LED chips directly contact with the metal plate of the metal chip PCB base plate and the heat emitted by the LED chips during operation can be quickly dissipated to the outside. Therefore, compared with the conventional light source, the LED light source has better heat dissipation effect.
