Beschreibung
Zusammenfassung:	The utility model discloses an LED linear light source. The LED linear light source comprises a shell, a condensing lens and LED lamp bars installed in the shell, wherein the condensing lens is a combined lens, the combined lens comprises two bar-shaped convexo-plane convex lenses separately arranged along the LED lamp bar light path, and the planes of the two convexo-plane convex lenses face the LED lamp bars. The LED linear light source adopts the two convexo-plane convex lenses and uses double lenses light condensation mode to perform secondary light condensation, the light rays are centralized, and the light intensity utilization rate is remarkably improved; compared with a single cylinder light condensation structure, the light intensity utilization rate can be improved by one time or above, therefore, on the same light outputting condition, the smaller driving current can be used, and the service life of the LED light source is improved.
