Abstract

The present invention is characterized by that in the front of LED light source a transparent plastic plate is placed, on said transparent plastic plate several through holes are cut, and formed into array light rod, the light rod is the through hole on the transparent plastic plate, its number and position are correspondent to the LED light source, a connection component is used for connecting the transparent plastic plate and light source seat into one body.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a light rod homogenizing device using a light emitting diode as a light source. Background technique [0002] Most of the various LED lamps sold in the market are similar to point light sources, or are area array light sources composed of similar point light sources. Bright spots in the middle and relatively dark spots on the sides and their superposition affect the lighting effect. Contents of the invention [0003] The object of the present invention is to provide a kind of uniform light device with LED as light source, which is composed of many lighting units, each lighting unit is composed of an LED light source and a light bar, and the light bar is arranged on the LED light source. The through hole on the front transparent plastic board, each LED light source is an approximate point light source, the light emitted by it passes through the principle of multiple reflections of the ligh...
