Abstract

The utility model relates to a novel LED street lamp reflecting cover which comprises a rectangular plate, a plurality of Y-direction grooves are arranged along the length direction of the rectangular plate, the section of each Y-direction groove is a Y-direction parabola, a plurality of pointed bulges which are formed by crossing two surfaces are arranged in the Y-direction grooves at intervals, a space which is clamped by the two adjacent bulges forms an X-direction groove in the width direction of the rectangular plate, the section of the X-direction groove is an X-direction parabola, the focuses of the X-direction parabola and the Y-direction parabola are coincided, the cross points of the X-direction grooves and the Y-direction grooves are provided with lamp holes which are used for installing light-emitting diodes (LED) positioned in the focuses of the parabolas, and the surfaces of the X-direction grooves and the Y-direction grooves are coated with high reflecting layers. The utility model can obtain a rectangular light spot after the light of the LED is reflected; because an X-direction parabola opening is larger, the long edge of the rectangular light spot is longer, the light spot can irradiate a long distance, thus, the distance between adjacent electric poles can be increased, and consequently, the engineering investment is reduced.

Description

The Novel LED street lamp reflection shield

Technical field

The utility model is a kind of reflection shield of lighting, particularly a kind of Novel LED street lamp reflection shield, and it can be widely used in and adopt in the illuminator of LED as light source.

Background technology

LED is a light emitting diode, having long service life, little, the no poisonous metal of heating, pollution-free, light almost all is advantages such as visible light, but LED also has weak point, if mainly be that the light that sends of LED is without secondary light-distribution, the hot spot of its formation is a circular light spot, the distance that circular light spot covered is very limited, so LED should not be directly used in the illumination of road.In the illumination of road, the face that we need hot spot to cover can be long as much as possible on the bearing of trend of road, so just can increase the distance of adjacent electric pole, thereby reduce the investment on the engineering.How improving the illumination coverage rate of LED, is problem to be solved in the utility model.

Summary of the invention

The utility model purpose is in order to overcome the narrow defective of existing LED illumination coverage rate, invent a kind of Novel LED street lamp reflection shield that can improve LED illumination coverage rate, LED is arranged in the lamp hole of this reflection shield, the light of LED can obtain a rectangular light spot after the reflection shield reflection, the long limit of this rectangular light spot can extend to far place.

The utility model purpose realizes as follows: described Novel LED street lamp reflection shield, comprise a rectangular slab, length direction along rectangular slab has many Y to groove, Y is that Y is to parabola to the section of groove, be provided with a plurality of pointed projectioies that form by two hand-deliver forks in that Y is equally spaced in groove, the X that the folded space of two adjacent protrusion constitutes the rectangular slab width is to groove, X to the section of groove be X to parabola, X overlaps to parabolic focus to parabola and Y; Have lamp hole to groove and Y to the crosspoint of groove at X, lamp hole is used to install LED, and LED is positioned on the parabolic focus; X has high reflector layer to groove and Y to the surface-coated of groove.

Described X respectively is four to groove and Y to groove, constitutes 16 identical little reflection shields altogether.

Described X is bigger to parabolical opening, and 120 degree that LED is sent can directly penetrate from the reflection shield edge with interior light.

Described Y is less to parabolical opening, and 60 degree that LED is sent can directly penetrate from the reflection shield edge with interior light.

Good effect of the present utility model is as follows: the utility model can make the light of LED obtain a rectangular light spot after reflection, because X is bigger to the opening of parabolic, so the long limit of rectangular light spot is very long, make hot spot can shine far place, so just can increase the distance of adjacent electric pole, thereby reduce the investment on the engineering.

The specific embodiment

As shown in Figure 1, described Novel LED street lamp reflection shield, comprise a rectangular slab 1, length direction along rectangular slab 1 has many Y to groove 2, Y to the section of groove 2 be Y to parabola, Y in groove 2 the equally spaced X of folded spaces formation rectangular slab 1 width of a plurality of pointed protruding 3, two adjacent protrusion that form by two hand-deliver forks 3 that is provided with to groove 4, X to the section of groove 4 be X to parabola, X overlaps to parabolic focus to parabola and Y; Have lamp hole 5 to groove 4 and Y to the crosspoint of groove 2 at X, lamp hole 5 is used to install LED, and LED is positioned on the parabolic focus; X has high reflector layer to groove 4 and Y to the surface-coated of groove 2.

Described X respectively is four to groove 4 and Y to groove 2, constitutes 16 identical little reflection shields altogether.

Described X is bigger to parabolical opening, and 120 degree that LED is sent can directly penetrate (see figure 2) with interior light from the reflection shield edge.

Described Y is less to parabolical opening, and 60 degree that LED is sent can directly penetrate (see figure 3) with interior light from the reflection shield edge.
