Abstract

The invention relates to an LED illumination device, in particular to an LED light source module comprising an LED light emitting module and a module base. The LED light source module is characterized by also comprising an optical cover plate which is fixedly arranged on the module base to define a closed space, wherein the LED light emitting module is arranged in the closed space; the outer surface of the optical cover plate is a plane or a smooth arc surface; the inner surface of the optical cover plate is provided with a plurality of inner sunken faces; the LED light emitting module is provided with a plurality of LED illuminants, an inner sunken face is correspondingly distributed at the front of each LED illuminant. The invention provides an LED light source module which is simple instructure and convenient to use.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED light source module. Background technique [0002] Compared with traditional street lights, LED street lights not only have the characteristics of good chromaticity, maintenance-free, and long life, but also are more energy-efficient than traditional street lights. [0003] Chinese utility model patent document CN201242086Y discloses a slot-type secondary optical lens that produces a rectangular spot. The slot-type secondary optical lens that produces a rectangular spot is a strip-shaped light-transmitting plate made of a light-transmitting material. A front transmission surface and a rear transmission surface are arranged on the strip, and the rear transmission surface includes a bottom projection surface parallel to the front transmission surface and a side reflection surface with an oblique angle to the front transmission surface, and a light source is formed on the main transm...
