Standard LED light source module for generating rectangular light distribution

Abstract

The invention relates to the technical field of LED light source modules, in particular to a standard LED light source module for generating rectangular light distribution. The standard LED light source module has a base; one or more LED module components are mounted on the base; each LED module component mainly consists of an LED chip and a lens matched with the LED chip for use; and the LED chips form the rectangular light distribution under the effects of corresponding lenses. The standard LED light source module for generating rectangular light distribution is prominent in energy saving effect and large in illumination area.

Description

technical field [0001] The invention relates to the technical field of LED light source modules, in particular to a standardized LED light source module that produces rectangular light distribution. Background technique [0002] See attached figure 1 And attached figure 2 , traditional street lamps are widely used in traffic road lighting, the existing ordinary LED light source light distribution usually can only present a circular light on the road surface, there will be shadows without light and overlapping parts of light, resulting in two adjacent circles It is easy to produce double images between the shapes and lights, and the overlapping parts have too strong light effects and the highest brightness, which causes a great waste of light sources and energy consumption.

Problems solved by technology

[0002] See attached figure 1 And attached figure 2 , traditional street lamps are widely used in traffic road lighting, the existing ordinary LED light source light distribution usually can only present a circular light on the road surface, there will be shadows without light and overlapping parts of light, resulting in two adjacent circles It is easy to produce double images between the shapes and lights, and the overlapping parts have too strong light effects and the highest brightness, which causes a great waste of light sources and energy consumption

[0003] See attached image 3 , at the same time, the light distribution area of ​​the existing ordinary LED light source is small, that is, the light span is small. Under the condition of light poles with a height of H, the distance between light poles can only reach W meters. In order to meet the lighting requirements of traffic roads, traditional The distribution distance between street lamps is also small, which invisibly increases the construction cost and maintenance cost of traditional street lamps, which is very uneconomical and environmentally friendly
