The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify.
As shown in Figure 1, the structure improved preferred embodiment of the utility model light fixture, these embodiment only supply the usefulness of explanation, in patent application, do not receive the restriction of this structure.Said fitting structure comprises:
One lamp housing 70, for having the hollow housing kenel of a ray cast mouth 71, these lamp housing 70 outsides are provided with an installing and locating portion 72, and lamp housing 70 inside then have one and are installed with space 73;
One light penetrating panel 80, assembling is positioned the ray cast mouth 71 of this lamp housing 70, and this light penetrating panel 80 has light transmission, by glass plate is constituted;
One reflector A is installed with and is positioned being installed with in the space 73 of this lamp housing 70, comprising:
One projection end epistylium 10 is established rectangular (comprising square, rectangle), is positioned at the predetermined light ejecting end of this reflector A;
One curved reflecting surface 20, curved aspect, this curved reflecting surface 20 comprises an arc inner edge portion 21 and is the oblique relatively two expansion edge portions 22 that extend out mutually that these two expansions edge portion, 22 outer ends are connected with wherein relative two sides of this projection end epistylium 10 mutually;
Most convex arc-shape reflection strips 30 are integrally formed at the arc inner edge portion 21 of this curved reflecting surface 20 and expand edge portion 22 inner surfaces, are parallel interval and arrange kenel, and respectively the section of this reflection strip is convex arc-shape;
Two tiltedly expand shape reflecting surface 40; Be the inclined-plane aspect that extends out relatively; This two oblique outer end of expanding shape reflecting surface 40 is connected with wherein relative in addition two sides of this projection end epistylium 10 mutually, and this two oblique inboard of expanding shape reflectings surface 40 is connected with relative two sides of this curved reflecting surface 20 mutually, and this at least one oblique expansion shape reflecting surface 40 offers an illuminator perforating 41; It is inner to penetrate reflector A when using illuminator 42 (like based on halogen bulb, LED bulb etc., only the being shown in shown in Figure 1) assembling for light fixture;
Prevent dazzling light lines 50, be integrally formed at these two oblique shape reflecting surface 40 surfaces of expanding and be matrix or convex lines aspect, in order to reach the effect that prevents to dazzle light;
Wherein, the relative angle X1 (being shown in shown in Figure 4) between this two oblique expansion shape reflecting surface 40 is between 80 ° to 100 °.
As shown in Figure 1; Several positions spaced apart, the outside of the ray cast mouth 71 of this lamp housing 70 are provided with the movable buckle assembly 74 that colludes; Ray cast mouth 71 places are formed with ring-type indent shoulder 75; For light penetrating panel 80 embedding groups wherein, and through each movable collude buckle assembly 74 inwardly collude the button be resisted against light penetrating panel 80 end faces so that this light penetrating panel 80 is reached the assembling positioning states.
As shown in Figure 1; Projection end epistylium 10 positions spaced apart of this reflector A are provided with several positional punches 11; Space 73 each opposite position that are installed with of this lamp housing 70 are convexly equipped with and are formed with a screw hole column 76; Utilize bolt 77 to wear the said positional punch 11 multiple screw locks of group with this, make reflector A reach positioning states in screw hole column 76.
Wherein, this prevents that dazzling light lines 50 is made as irregular grid type lines kenel (as shown in Figure 2); The anti-light lines 50B that dazzles perhaps as shown in Figure 8 is set as the grid type lines kenel of regular shape, like well word, grid, honeycomb etc.
