In above-mentioned LED Grille lamp, the angle of inclination of described middle reflector is 70 °～85 °.

In above-mentioned LED Grille lamp, described cavity bottom is fixed with 1-4 bar LED module, and setting parallel to each other between LED module.

In above-mentioned LED Grille lamp, place, the relative LED module fixed position, bottom of described lamp body offers bar shaped heat radiation through hole.The radiator of LED module is arranged on bar shaped heat radiation through hole, facilitates the back of LED module to contact with outside air through bar shaped heat radiation through hole, accelerates radiating rate.

In above-mentioned LED Grille lamp, the sidewall of described lamp body offers groove, and LED module two ends are embedded in groove.LED module two ends embed in cavity side walls, and LED module and lamp body are fixed.

In above-mentioned LED Grille lamp, described LED module is connected mutually by screw and lamp body bottom.By screw, make LED closely be connected in lamp body bottom, be not easy to come off.

In above-mentioned LED Grille lamp, described LED module comprises radiator, aluminium base and is connected in the some LED light sources on aluminium base, and described aluminium base is embedded in radiator inner side, and described radiator outside is also connected with the diffuser that is circular arc.Diffuser can be eliminated a part of dazzle, and sealing LED light source reaches good efficient light output; Heat in module is directly delivered on radiator by aluminium base, good heat dissipation effect.

Compared with prior art, the LED light source of this LED Grille lamp emits beam through after diffuser, part dazzle is eliminated, effect by reflector afterwards all reflexes to face to be illuminated light, realize secondary light-distribution object, make Luminaire efficiency >=95%, effectively eliminate dazzle and reach good distribution curve flux.
