Abstract

The invention discloses a light-emitting diode (LED) lighting module with a light guiding device. The LED lighting module with the light guiding device comprises an LED lighting unit which comprises a lamp head and a pin for supplying power for the lamp head. The light guiding device is arranged above the LED lighting unit and connected with the LED unit in a buckled mode. Due to the light guiding device connected with the LED lighting unit in a buckled mode and a first light guiding portion and a second light guiding portion of a cone of the light guiding device are used at the same time, the LED lighting module can greatly improve light guiding effect and light gathering effect of the whole light guiding device, enable light of the LED to be gathered effectively and reduce light leakage rate.

Description

technical field [0001] The invention relates to an illuminating device, more specifically, an LED illuminating module with a light guiding device. Background technique [0002] LED is an abbreviation taken from the three words Light Emitting Diode, which translates as "light emitting diode" in Chinese. As the name suggests, a light emitting diode is an electronic device that can convert electrical energy into light energy and has the characteristics of a diode. The light leakage rate of existing LED lamps remains high, resulting in a great waste of light sources and electric energy. [0003] Chinese invention application 200810087113.4 discloses an LED spotlight including: RGB-LED light source composed of red, green and blue light-emitting diodes and a concentrator for converging the mixed-color light beam projected from the RGB-LED light source to the incident end surface of the rod lens A lens; a tapered rod lens whose cross-section converges from an incident end face to ...
