Problems solved by technology

The light distribution form obtained by the above two light distribution processes is a symmetrical batwing light distribution, that is: the C0-180 light distribution curve is a symmetrical batwing shape, and the C90-270 light distribution curve is a symmetrical approximately elliptical or approximately conical shape , but for street lighting applications, this form of light distribution is unreasonable, especially for motor vehicle lanes, this form of light distribution is lower than the utilization rate of lighting luminous flux of asymmetrical batwing light distribution

Abstract

The invention discloses a light-emitting diode (LED) light source and a LED light source module formed by a plurality of LED light sources. The LED light source comprises a LED lighting body and a reflector, wherein the reflector is a side wall closed cavity. The structural mode of the LED light source is: a C0-180 section cutaway view outline is a curvilinearfigure outline with the center being the highest point and gradually reducing the height toward the left side and the right side. The C0-180 section cutaway view outline is symmetrical on the left and the right. A C90-270 section cutaway view outline is a curve type outline with the left side or the right side being the highest point and gradually reducing the height toward the other side or first reducing and then heightening. The C90-270 section cutaway view outline is unsymmetrical on the left and the right. A horizontal cross section cutaway view outline of the reflector is a closed curve, and the closed curve is provided with a section or multiple sections of cove arc lines. The LED light source can achieve a plurality of unsymmetrical light distribution, and improves lighting light flux use ratio.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED light source and an LED light source module composed of a plurality of such LED light sources. Background technique [0002] LED is easy to realize various forms of light distribution, and the corresponding LED light source can be formed through the primary light distribution process and the secondary light distribution process. The primary light distribution process is to package the lens on the packaging bracket in the process of making the LED package single lamp, so that it is integrated with the light-emitting chip, fluorescent glue and packaging bracket to form an LED single lamp. The common types of LED single lamps are: In-line type, SMD type, high-power package type, etc. Among them, the surface of the light-emitting chip is coated with fluorescent glue, and the lens is generally a silicone lens; this process is equivalent to a one-time realization in the pro...
