As the LED anti-dazzle modules A M of Fig. 5 and embodiment 1 described asymmetric luminous intensity distribution, contain two monoblock type parts a that are applied to the reflector overall package of LED lighting module.In the described LED anti-dazzle of present embodiment module, there is the monoblock type parts a of two reflector overall package to be machined directly to a monoblock type parts A who is applied to the reflector overall package of LED illumination module.Simultaneously, the LED anti-dazzle modules A M of two asymmetric luminous intensity distributions, its shielding glazing bar 3 that is positioned at same LED lighting unit U position also directly is processed into an integrally assembled type shielding glazing bar B who is applied to LED anti-dazzle illumination module, and acts on the LED anti-dazzle modules A M of two asymmetric luminous intensity distributions simultaneously.
The monoblock type parts A of the reflector overall package of the described LED of being applied to illumination module is that specular aluminium sheet material material is made; The integrally assembled type shielding glazing bar B of the described LED of being applied to anti-dazzle illumination module is that transparent PC material is made, and surperficial frosted is handled.
Above drawings and Examples are to cover the included content of the present invention fully for the present invention being further specified, should not be construed as.
