Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Example 1.

Referring to Fig. 1, Fig. 2, Fig. 3, a kind of LED grille lamp for subway station, its structure includes grille lamp profile 1, LED light source 2, profile end 3, grille reflector 4, face shield 5, installation lamps and lanterns Fixed plate 6, LED driver 7.

Grille lamp profile 1 is a stretchable shell, the length of which can be adjusted according to actual needs. There are comb-shaped heat dissipation fins on the outer side of the housing, slots 9 are provided at the lower end, and U-shaped grooves 10 are provided at the top. Grille lamp profile 1 provides structural support for other components of the lamp.

The LED light source 2 is located inside the grille light profile 1 and is fixed on the U-shaped groove 10 of the grille light profile 1 by screws.
