The specific embodiment
Below in conjunction with accompanying drawing, further explain is done in preferred embodiment of the present invention.
Airport vertical type with error-proof structure provided by the invention advances low beam; Shown in Fig. 1 to 9; Comprise transparent member 3 that lamp housing 4, exiting surface be made up of several rectangle bead faces 32, transparent member 3 is fastenedly connected light cover 1 at lamp housing 4 openends, is nested in the sealing ring 2 that transparent member 3 edges are used to seal light cover 1 and lamp housing 4 through screw 6, and install reflector 5 at lamp housing 1 inner chamber; Wherein, offer fool proof recess 11 at the madial wall of light cover 1, this fool proof recess 11 is along this light cover 1 longitudinal direction setting, and its width is about 20mm, the degree of depth is about 2mm; Be provided with grooved fool proof projection 21 at sealing ring 2 lateral walls, also be provided with fool proof projection 31 at the lateral wall of transparent member 3; When advancing the low beam assembling, in the fool proof projection 31 adaptive insertion grooved fool proof projections 21, and grooved fool proof projection 21 adaptive snapping in the fool proof recess 11.Like this; This airport vertical type with error-proof structure advances low beam; Through the fool proof recess being set on the light cover, on transparent member and seal, being provided with and the suitable fool proof projection of fool proof recess, and be arranged on the light cover the fool proof alignment pin be arranged on the fool proof alignment pin on the lamp housing open end; Like this, when this light fixture of assembling, just can guarantee that transparent member keeps the luminous intensity distribution fitting limit, reaches the illuminance and the hot spot uniformity that improve light fixture.Simultaneously, adopt the transparent member of the little sphere of rectangle, can optimize the into illuminance and the hot spot uniformity of low beam.
Better go out light effect in order to reach; The present invention has done further technological improvement; Shown in Fig. 2 and 9; Inner surface at light cover 1 is provided with a fool proof alignment pin 12, on the end face of lamp housing 4 openends, is provided with a fool proof locating hole 41, and the fool proof recess 11 of light cover 1 and the angle between the fool proof alignment pin 12 are 135 ± 0.5 °.
For making things convenient for the installation between light cover 1, transparent member 3 and the lamp housing 4 and reaching better sealing effectiveness; Shown in Fig. 3 and 4; Sealing ring of the present invention 2 adopts the flute profile sealing rings, and the outer surface up and down of sealing circle respectively is provided with annular groove 22, and is as illustrated in Figures 5 and 6; This annular groove 22 rotates at light cover 1 will provide a deformation space for the horizontal interference of sealing ring 2 when fastening, and then the reverse torsion that sealing ring 2 produces when reducing light cover 1 rotation.
Shown in Fig. 7 and 8, on the one hand, the light-entering surface of transparent member 3 is the plane, can guarantee that like this incident ray horizontal linear injects, to reach the effect that improves luminous flux; On the other hand, the spherical radius of rectangle bead face 32 is set to 37 ± 0.5mm, and rectangular length is 24mm, and width 12mm can guarantee that light reaches preferable spotlight effect when penetrating.
As shown in Figure 7, the long limit of each rectangle bead face 32 is parallel with the diameter that passes fool proof projection 31, and the long limit of each rectangle bead face 32 is parallel to the ground.Like this, guarantee that transparent member keeps the luminous intensity distribution fitting limit, reaches the illuminance and the hot spot uniformity that improve light fixture.
Whole when advancing low beam and installing; Earlier the fool proof projection of transparent member is aimed at the grooved fool proof projection place of sealing ring, in the seal groove of packing into then, made sealing ring be nested in the transparent member edge; Simultaneously reflector and sealing ring surface are fitted, transparent member, sealing ring and reflector form an integral body at this moment; Then, the grooved fool proof projection of sealing ring is aimed at light cover fool proof indent, the lamp holder of packing into together lid; Then as a whole with transparent member, sealing ring, reflector and light cover; The fool proof alignment pin of light cover is aimed at the fool proof locating hole of lamp housing; One reinstates screw accomplishes the lamp body assembling; Can guarantee that sealing effectiveness is good this moment, and the sphere longer sides that guarantees transparent member simultaneously guarantees light distribution effect at horizontal level.
