Embodiment 1

[0079]As shown in Figure 5, an asymmetric light distribution LED anti-glare lighting module AM ​​consists of multiple LED lighting units U with asymmetric light distribution and anti-glare characteristics that are repeatedly arranged along the axis direction of the composite reflector 2 get. The LED lighting unit U constituting the LED anti-glare lighting module AM, its light distribution characteristic perpendicular to the axis direction of the composite reflector 2 is provided by the composite reflective surface of the composite reflector 2, which is a wing-type light distribution; The glare in the axial direction of the type reflector 2 is suppressed by the shielding grid bar 3 . The light distribution of the LED anti-glare lighting module AM ​​with asymmetrical light distribution is similar to the light distribution of a single LED lighting unit Ud, which is a flank light distribution.

Embodiment 2

[0083] As shown in Figure 6, another LED anti-glare lighting module AM ​​with asymmetric light distribution consists of a plurality of LED lighting units U with asymmetric light distribution and anti-glare characteristics repeated along the axis direction of the compound reflector 2. Arranged to get. The LED lighting unit U constituting the LED anti-glare lighting module AM, its light distribution characteristic perpendicular to the axis direction of the composite reflector 2 is provided by the composite reflective surface of the composite reflector 2, which is a wing-type light distribution; The glare in the axial direction of the type reflector 2 is suppressed by the shielding grid bar 3 . The light distribution of the LED anti-glare lighting module AM ​​with asymmetrical light distribution is similar to the light distribution of a single LED lighting unit U, which is a wing-type light distribution.

Abstract

An anti-glare LED illuminating apparatus belongs to the semiconductor illuminating technology field and is characterized by being provided with an anti-glare LED illuminating unit U, which comprises an LED light source 1, a combined type reflector 2 and a shielding lace bar 3, or an LED anti-glare illuminating module or an LED anti-glare illuminating die set consisting of the anti-glare LED illuminating unit, the LED light source is arranged between two adjacent shielding lace bars 3, the inner wall of the combined type reflector 2 is an asymmetry reflection plane, optical intensity is distributed asymmetrically along the direction vertical to the combined type reflector 2 axes, a light distribution curve is of lateral wing type, the shielding lace bar 3 limits the glare generated by the LED light source 1 along the axial direction of the combined type reflector 2. The invention has scientific design, reasonable structure, easy production, convenient assembly and good anti-glare effect, reduces the difficulties of manufacturing, processing and assembly and production cost, thus being beneficial to large-scale application.

Description

technical field [0001] The invention relates to an anti-glare LED lighting device of an LED lighting unit with asymmetrical light distribution and anti-glare characteristics, and belongs to the technical field of semiconductor lighting. Background technique [0002] In the design of lighting optics, there are many places where the light distribution requirements of lighting devices are flank-type light distribution. (As shown in Figure 1A) this light distribution feature is that the light intensity is distributed asymmetrically on one side of the 0° direction axis; There are also many places where the light distribution requirements for lighting devices are batwing light distribution (as shown in Figure 1B). light intensity value. [0003] The LED light source is different from the traditional electric light source. The light intensity distribution of the LED light source in the three-dimensional space has a certain directionality. At present, the light intensity distributi...
